Corporate Tax 2026 Comparisons

Overview

In Australia, the company is the most common corporate form for businesses. Companies can be registered as proprietary companies or public companies, with proprietary companies being most prevalent for small to medium businesses.

Corporate Forms and Company Types

Proprietary companies may be limited by shares or unlimited with share capital, while public companies may be limited by shares, limited by guarantee, unlimited with share capital, or operate as no-liability companies. The legislation also permits the registration of corporate collective investment vehicles (CCIVs) limited by shares. A company comes into existence as a body corporate at the beginning of the day on which it is registered, establishing its status as a separate legal entity from that moment.

Proprietary companies are the most common corporate structure for small to medium businesses, limited to a maximum of 50 non-employee shareholders and prohibited from engaging in activities that would require lodging a prospectus with the Australian Securities and Investment Commission. These naming requirements serve to warn third parties about the nature and limitations of the corporate structure with which they are dealing.

A company is a separate legal entity distinct from its members. This principle is preserved even where there are multiple companies in a group. This means that creditors of a subsidiary company can look only to that company for payment of their debts, and cannot seek payment from the holding company in the absence of contractual arrangements creating additional rights.

Taxation of Corporate Structures

Companies are taxed as separate legal entities under Australian income tax law. This tax treatment reflects their status as distinct legal persons. However, this also means that tax losses are trapped within the company and cannot be utilised directly by shareholders.

In contrast, companies constituting consolidated groups and multiple entry consolidated groups (“MEC groups”) are not taxed as separate legal entities. Under the single entity rule, subsidiary members of a consolidated group are taken to be parts of the head company, rather than separate entities, for the purposes of working out income tax liability. The head company becomes solely responsible for the group’s tax obligations, and subsidiary members lose their separate income tax identities for periods when they are part of the consolidated group. MEC groups, which are consolidated groups formed by foreign-owned Australian entities, are treated identically to consolidated groups, meaning the single entity rule applies equally to them.

CCIVs are not taxed as separate legal entities in Australia. Instead, they are flow-through entities whereby each sub-fund of a CCIV is treated as a separate unit trust for taxation purposes. While a CCIV is legally structured as a company limited by shares, the tax regime deems the CCIV to be the trustee of each sub-fund, with the sub-fund assets treated as trust property and members treated as beneficiaries. This approach provides CCIVs with flow-through taxation rather than the entity-level taxation that ordinarily applies to companies, allowing income to be attributed to members based on their individual tax attributes.

Overview

Transparent entities in Australia are business structures that are not taxed as separate entities, with income instead flowing through to individual owners or beneficiaries who are taxed at their personal marginal rates. The two primary transparent entities are partnerships and trusts.

Sector-Specific Transparent Structures

Different transparent entities serve distinct business sectors based on their specific characteristics and benefits. Partnerships are the most common form of legal vehicle for professional services businesses, such as accounting practices, legal practices and engineering practices, being most ideal where the business provides specialist professional services and the business owners are the core of the business employees.

The advantages of partnerships include:

• income splitting;
• joint control among partners;
• sharing of workload and losses;
• flexibility in sharing profits and losses; and
• tax advantages such as the ability to income split and the ability of partners to access the 50% capital gains tax discount. 

While partnerships lodge tax returns, they are not liable to pay the tax, with this liability resting with the individual partners, and the partnership and property ownership can be controlled by the terms of the partnership deed, making this arrangement suitable for continuing business transactions.

Discretionary trusts have become important estate planning and business structures, particularly where flexibility in applying income and capital is desired, or where beneficiaries need protection from themselves, creditors or spouses. The tax benefits arise from the fact that income is not taxed within the trust unless accumulated, but rather at the marginal tax rate of the beneficiary receiving distributions, with the particularly effective benefit that children under 18 years of age are entitled to the full adult tax-free threshold on trust income received rather than penalty rates applying to other unearned income received by minors.

Unit trusts, while sharing trust characteristics, provide fixed interests to unit holders with entitlements directly related to their capital contributions, and are typically used to hold major and long-term assets of a business rather than as operating structures themselves.

For investment groups, incorporated limited partnerships are typically used for international venture capital investment. Unlike common law partnerships and limited partnerships, an incorporated limited partnership is a separate legal entity from its partners, with general partners who manage the business and limited partners who contribute investment capital but do not manage the business, and with the liability of the limited partners for debts and obligations accordingly limited. These structures have the legal capacity and powers of a body corporate while maintaining partnership characteristics suitable for venture capital arrangements.

Managed investment schemes also serve the investment sector, pooling contributions from multiple investors to produce financial benefits through collective investment in assets such as real property, shares and mortgages.

Companies incorporated in Australia are automatically resident for tax purposes, while foreign-incorporated companies are resident if they carry on business in Australia and have either their central management and control in Australia or voting power controlled by Australian resident shareholders.

A trust estate is resident if a trustee was resident at any time during the income year or the central management and control of the trust was in Australia at any time during the year.

Partnerships are generally fiscally transparent entities that are not separate taxable entities. While partnership net income is calculated as if the partnership were a resident taxpayer, tax liability falls on individual partners who include their share in their individual returns according to their residency and the source of the income.

The residency of each entity may be modified by the application of an applicable double tax agreement.

In Australia, incorporated businesses are subject to a flat corporate tax rate of 30%, with certain companies qualifying as base rate entities eligible for a reduced rate of 25%.

Individuals operating businesses directly as sole traders, or through transparent entities such as partnerships and trusts, are taxed at progressive marginal rates ranging from nil (for income up to AUD18,200) to 45%, plus a Medicare levy of 2%.

Partnerships are transparent entities, with partners individually taxed on their proportionate share of partnership net income at individual rates. Similarly, trust beneficiaries presently entitled to, or attributed, trust income are taxed at individual rates.

Overview

Corporate taxable income in Australia is calculated using a statutory formula that differs fundamentally from accounting profit. Taxable income is calculated by deducting allowable deductions from assessable income. While accounting principles inform the calculation method for trading businesses, which must use an accruals basis, accounting profit does not determine taxable income. Accordingly, substantial adjustments are required, including differences in depreciation, the exclusion of capital expenditure and entertainment expenses, and various timing differences.

Substantial Adjustments Required for Tax Purposes

Significant adjustments are required to convert accounting profit to taxable income. The most substantial relates to depreciation and capital allowances. While accounting standards permit depreciation of assets, tax law provides its own regime allowing deductions for the decline in value of depreciating assets. Division 40 permits taxpayers to deduct amounts equal to that decline using either the diminishing value or prime cost method over the asset’s effective life, often differing materially from accounting depreciation.

Capital expenditure creates a fundamental adjustment. Immediate deductions for capital outgoings are disallowed. Australian courts distinguish capital from revenue expenditure, characterising capital expenditure as strengthening the business structure rather than being part of its ordinary income-earning operations. Many items expensed for accounting purposes must therefore be capitalised for tax purposes, or vice versa.

Entertainment expenses, defined as entertainment by way of food, drink or recreation, are generally non-deductible regardless of business purpose. Deductions for expenditure incurred in deriving exempt income are also disallowed, requiring adjustments where both taxable and exempt income streams exist.

Accruals Versus Receipts Taxation

The appropriate basis depends on the nature of the business. Trading and manufacturing businesses must use accruals, as profit may be contained in stock and outstandings. However, the method must give a substantially correct reflex of the taxpayer’s true income. For some professional practitioners with simple accounting systems and no circulating capital, a cash receipts basis may be appropriate. Whether receipts or accruals is correct remains a question of fact in each case.

Australia does not operate a patent box regime or provide concessional tax rates for income derived from intellectual property. However, the Australian corporate tax system provides a substantial R&D tax incentive, which offers tax offsets for eligible R&D expenditure. R&D entities with aggregated turnover below AUD20 million receive a refundable tax offset at their corporate tax rate plus 18.5 percentage points, while larger entities receive their corporate tax rate plus an R&D premium for expenditure exceeding specified thresholds.

Intellectual property itself is treated as depreciating assets, allowing standard depreciation deductions without special concessions.

Australia’s corporate tax regime provides targeted incentives to encourage specific activities, support particular industries, and promote innovation and small business growth. The principal incentives include the R&D tax offset, which provides refundable or non-refundable tax offsets for eligible R&D expenditure.

Industry-specific incentives include three film production tax offsets, immediate deductions for mining and petroleum exploration expenditure, and shipping income exemptions.

Small business entities with aggregated turnover below AUD10 million have access to multiple concessions, including simplified depreciation, capital gains tax concessions, and an income tax offset, while investors in early-stage innovation companies receive tax offsets and capital gains tax exemptions.

Under Australian law, companies may carry forward tax losses indefinitely to deduct against future assessable income, provided they satisfy either the continuity of ownership test or the business continuity test. 

Eligible corporate tax entities with aggregated turnover below AUD5 billion may also carry back losses incurred between 2019–20 and 2022–23 to earlier years (but not before 2018–19) to generate a refundable tax offset. However, capital losses are strictly quarantined and can only offset capital gains, not ordinary income, while revenue losses may offset any assessable income including net capital gains.

Interest deductions claimed by local corporations are subject to several layers of limitation. At the general level, interest must satisfy the requirements of deductibility by being incurred in gaining or producing assessable income or necessarily incurred in carrying on a business.

More specifically, Australia’s thin capitalisation rules impose limits on debt deductions where debt levels exceed prescribed safe harbour ratios or arm’s length benchmarks. Additionally, the debt-equity rules determine whether instruments are characterised as debt or equity for tax purposes, affecting whether returns are deductible, while the general anti-avoidance rule may disallow interest deductions where arrangements are entered into for the dominant purpose of obtaining a tax benefit.

Wholly owned groups of resident entities may elect to consolidate for income tax purposes, creating a single entity for tax purposes where subsidiary members are treated as parts of the head company. The head company must make an irrevocable written election, after which the single entity rule applies, allowing losses from across the group to be aggregated and offset against group income.

Where consolidation is not available or not elected, wholly owned groups may transfer losses between member companies by written agreement, while individual companies can only deduct their own prior year losses if they satisfy either the continuity of ownership test or the same or similar business test.

Corporations are taxed on capital gains by including any net capital gain in their assessable income, which is then taxed at the applicable corporate income tax rate. Unlike individual taxpayers and trusts, companies cannot access the 50% capital gains tax (CGT) discount, meaning they must include the full amount of their net capital gain in assessable income.

However, corporations can access various exemptions and reliefs, including:

• exemptions for pre-CGT assets acquired before 20 September 1985;
• rollover relief provisions for corporate restructures and scrip-for-scrip transactions;
• capital loss transfer arrangements within corporate groups; and
• small business CGT concessions if they satisfy the relevant conditions.

Capital Losses and Group Relief

Companies cannot deduct capital losses from normal assessable income, but they can offset capital losses against capital gains in the current income year or carry them forward to reduce capital gains in later years. An important relief mechanism available to companies is the ability to offset a net capital loss against a capital gain in another company by passing either the ownership test or the same or similar business test in relation to the capital loss year, the capital gain year and intervening years.

Additionally, capital losses can be transferred between group companies, providing significant flexibility for corporate groups to manage their overall tax position by consolidating gains and losses across related entities.

Exemptions and Rollover Relief

Several exemptions and relief mechanisms reduce or defer corporate CGT liability. Assets acquired before 20 September 1985 are exempt from CGT.

Rollover relief allows companies to defer capital gains tax from one CGT event to another by replacing a CGT asset with another asset, or where the same asset is subject to the event. Scrip-for-scrip rollover relief is available where a vendor acquires shares in the purchaser entity or an entity within the purchaser’s group as consideration for shares sold, provided the purchaser has acquired at least 80% of the target’s total share capital. In receiving scrip-for-scrip rollover relief, the vendor defers paying CGT until it sells the purchaser’s shares received as consideration. The rollover provisions can apply to transfers of assets between companies, though rollover relief is not available if the asset becomes trading stock or is a depreciating asset.

Small Business CGT Concessions

Companies can access small business CGT concessions if they satisfy the basic conditions for relief. The basic conditions require that:

• a CGT event happens in relation to a CGT asset;
• the event would have resulted in a capital gain;
• the company is a CGT small business entity or satisfies the maximum net asset value test; and
• the CGT asset satisfies the active asset test.

Where the CGT asset is a share in a company, additional conditions must be satisfied, including that, just before the CGT event, either the taxpayer is a CGT concession stakeholder in the object entity or CGT concession stakeholders together have a small business participation percentage of at least 90%.

The available concessions include the 50% active asset reduction, the small business retirement exemption and the small business rollover provisions.

Beyond income tax, incorporated businesses in Australia may be liable for several transaction-based taxes under Commonwealth and state legislation. At the Commonwealth level, goods and services tax (GST) applies at 10% to the transfer of business assets and real property, although transactions can be structured into exemptions.

State and territory governments impose stamp duty (transfer duty) on certain direct and indirect property transfers, though duty on business asset transfers was abolished in New South Wales, Victoria and South Australia from 1 July 2016.       

At the Commonwealth level, companies must charge GST on taxable supplies, and fringe benefits tax (FBT) when providing non-cash benefits to employees.

State and territory governments impose payroll tax on wages exceeding specified thresholds, and annual land tax.

Companies are subject to Pay As You Go (PAYG) withholding obligations for employee wages. Companies that employ staff must also make superannuation guarantee contributions equal to 12% of ordinary time earnings subject to certain limits.

Industry-specific taxes include luxury car tax (LCT) at 33%, wine equalisation tax (WET) at 29%, and customs duties.

Most closely held local businesses in Australia operate in non-corporate form. According to 2019 statistics from the Australian Small Business and Family Enterprise Ombudsman, 62% of Australian businesses are sole traders with no employees.

When examining tax return filings for business entities in 2015–16, non-corporate structures collectively outnumber corporate structures; while 941,166 returns were filed for companies, combined filings for trusts (845,925) and partnerships (321,360) totalled 1,167,285. This indicates that the majority of small businesses in Australia do not operate as, or through, companies.

Australia employs a comprehensive regulatory framework to prevent individual professionals from inappropriately accessing lower corporate tax rates through income diversion arrangements. The primary mechanism is the personal services income rules, which attribute income earned through personal services entities directly to the individual service provider unless genuine business tests are satisfied.

This is supplemented by deemed dividend rules, which treat payments, loans and debts forgiven from private companies to shareholders as dividends. The general anti-avoidance rule also applies to income splitting and profit retention schemes even where personal services business status has been achieved.

Australia’s deemed dividend rules operate as an automatic anti-avoidance regime that deems certain payments, loans and debt forgiveness by private companies to shareholders or their associates to be dividends, thereby ensuring that accumulated profits cannot be distributed in tax-free forms. Additionally, the general anti-avoidance rule targets dividend-stripping schemes where shareholders avoid tax on company profits through arrangements that provide capital sums instead of taxable dividends. These provisions operate to prevent the improper retention and distribution of earnings rather than prohibiting accumulation itself.

Individuals are taxed on dividends from closely held corporations (private companies), with dividends included in assessable income. Australia’s dividend imputation system allows franked dividends to carry franking credits representing company tax already paid, which individual shareholders include in assessable income and receive as tax offsets.

Australia’s deemed dividend rules deem certain payments and loans by private companies to shareholders to be unfranked dividends to prevent profit extraction without proper taxation.

Capital gains on share disposals are taxed subject to CGT, with individuals entitled to a 50% CGT discount if shares are held for more than 12 months. Small business CGT concessions may provide substantial relief, including the 15-year exemption, 50% active asset reduction, and retirement exemption.

Please see 3.4 Taxation of Individuals on Shares in Closely Held Corporations.

In the absence of tax treaties, Australia imposes withholding tax on dividends, interest and royalties paid to non-residents at statutory rates of 30% for unfranked dividends, 10% for interest and 30% for royalties.

However, significant reliefs are available under domestic law – most notably the complete exemption for franked dividends, and the exemption for interest on publicly offered debentures satisfying prescribed public offer tests.

The Australian Taxation Office (ATO) demonstrates particular determination to collect withholding taxes in areas involving cross-border intellectual property arrangements, payment characterisation disputes, and schemes using interposed entities to avoid withholding tax, deploying both specific anti-avoidance provisions and the general anti-avoidance rule.

Foreign investors making inbound portfolio investments into Australian corporate stock or debt primarily utilise double taxation agreements (DTAs) with countries including Singapore, the United States, the United Kingdom, the Netherlands, Switzerland, Japan, New Zealand and Canada.

Under Australian domestic law, dividends paid to non-residents are subject to 30% withholding tax and interest to 10% withholding tax. However, Australia’s DTAs typically reduce the dividend withholding tax rate to 15% while maintaining the 10% rate on interest and royalties.

Fully franked dividends are exempt from withholding tax, and exemptions also apply to interest on publicly offered debentures. These treaty benefits, combined with beneficial ownership requirements and the respect for corporate structures under Australia’s treaty network, make these jurisdictions attractive conduits for foreign portfolio investment into Australian equity and debt securities.

Historically, Australian tax authorities have shown limited success in challenging the use of treaty country entities by non-treaty country residents for inbound investments. In the Resource Capital Fund litigation (2013–2019), the Commissioner challenged treaty entitlement for Cayman Islands limited partnerships with US resident partners, but the Full Federal Court ultimately permitted treaty benefits to flow through fiscally transparent partnerships where underlying partners were treaty country residents.

The Commissioner’s approach changed following these cases, as evidenced by a subsequently revised tax determination, which confirms that treaty benefits may flow through transparent entities even when the entity itself is not a treaty resident. 

While Australia implemented the OECD Multilateral Instrument with its principal purpose test from 1 January 2019, no reported cases yet apply this measure to deny treaty benefits based on treaty shopping concerns.

For inbound investors operating through Australian corporations, the biggest transfer pricing issues arise from Australia’s self-executing transfer pricing rules, which require all cross-border related-party transactions to be conducted on arm’s length terms.

The most significant compliance challenges involve four transaction-specific areas:

• cross-border related-party financing arrangements, where both pricing and debt quantum must satisfy arm’s length principles;
• inbound distribution arrangements, where Australian subsidiaries must demonstrate appropriate profit margins relative to functions performed;
• intangibles-related transactions, particularly the migration of intangible assets offshore and payments for intellectual property use, which face heightened ATO scrutiny regarding substance and characterisation of Australian activities; and
• documentation obligations, where failure to maintain contemporaneous transfer pricing documentation precludes establishing a reasonably arguable position and exposes taxpayers to significant penalties.

The ATO actively challenges related-party, limited risk distribution arrangements for inbound investments through a comprehensive risk-based compliance framework and targeted enforcement actions.

The Commissioner may make determinations negating transfer pricing benefits where conditions between related entities differ from those between independent enterprises. The ATO establishes a three-tiered risk assessment system specifically for inbound distributors, with escalating compliance responses for arrangements falling outside low-risk parameters.

The ATO particularly scrutinises entities characterised as limited risk distributors that perform economically significant functions, assume substantial risks, or generate persistent losses, as demonstrated in publicly available guidance materials.

Australia’s transfer pricing framework for inbound investments incorporates the OECD’s Transfer Pricing Guidelines (the “OECD Guidelines”) through domestic enactment, but significant variations from OECD standards exist in both rules and enforcement. The most substantial departures include:

• mandatory year-by-year assessment without cross-year aggregation;
• retrospective application of the transfer pricing rules to transactions from 2004;
• statutory authority to reconstruct pricing methodologies while prohibiting reconstruction of other contractual terms; and
• a flexible rather than rigid application of OECD Guidelines – Australian courts have established that the OECD Guidelines provide interpretative guidance only and do not override the domestic statutory framework.

The ATO has adopted a more structured and risk-focused approach to transfer pricing enforcement for inbound investments, though this reflects strategic refinement rather than arbitrary aggression.

Recent publicly available guidelines targeting inbound distribution arrangements, cross-border financing, and intangibles migration demonstrate heightened scrutiny, particularly for loss-making entities. Major litigation successes in cases confirm the ATO’s willingness to challenge substantial arrangements.

The Mutual Agreement Procedure (MAP) provides an effective mechanism for resolving transfer pricing disputes, with Australia historically achieving full relief in approximately 95% of MAP cases, though resolution timelines frequently exceed two years for transfer pricing matters.

Compensating adjustments are allowed when transfer pricing claims involving foreign companies are settled in Australia, through multiple mechanisms depending on the context.

Under domestic law, the Commissioner is empowered to make consequential adjustment determinations for disadvantaged entities where it is fair and reasonable to do so, preventing double taxation.

Australia’s DTAs also provide for appropriate adjustments to relieve economic double taxation when a treaty partner makes a primary transfer pricing adjustment on an arm’s length basis. In advance pricing arrangements, compensating adjustments are mandatory when actual results fall outside agreed arm’s length outcomes. However, these adjustments operate as separate procedural mechanisms from primary transfer pricing determinations and require specific requests by taxpayers after resolution of the underlying transfer pricing issues.

Local branches of non-local corporations are taxed differently to local subsidiaries of non-local corporations in Australia. An Australian branch is part of the foreign parent entity and remains a non-resident for tax purposes, meaning it is taxed only on Australian source income.

In contrast, an Australian subsidiary is a separate legal entity that is typically an Australian tax resident (if incorporated in Australia or having central management and control in Australia) and is therefore taxed on its worldwide income.

The most significant practical difference arises in profit repatriation. Subsidiaries must pay dividends to their foreign parent which are subject to dividend withholding tax, whereas branches can remit profits to their foreign parent without incurring dividend withholding tax, as they do not pay dividends but simply transfer funds within the same legal entity.

Non-resident companies can disregard capital gains on the disposal of shares in Australian corporations unless those shares constitute taxable Australian property. Shares in Australian companies are only taxable Australian property if they are indirect Australian real property interests, which requires satisfying both the non-portfolio interest test (holding more than 10% of the company) and the principal asset test (more than 50% of the company’s assets by market value being taxable Australian real property).

The same framework applies to indirect capital gains where a non-resident sells shares in a foreign holding company that owns shares in an Australian corporation, as the principal asset test applies through layered ownership structures.

Australia’s bilateral tax treaties generally do not eliminate these CGTs, as modern treaties typically include provisions that specifically allocate taxing rights to Australia for gains on shares in land-rich companies.

Australia has several change-of-control provisions that can trigger tax or duty charges for foreign companies, and these provisions can apply to disposals of indirect holdings higher up in overseas groups.

At the Commonwealth level, capital gains tax is imposed on foreign residents disposing of indirect Australian real property interests where the interest passes both the non-portfolio interest test (greater than 10% holding) and the principal asset test (where more than 50% of the entity’s value derives from Australian real property).

At the state and territory level, all Australian jurisdictions impose landholder duty on acquisitions of significant interests (typically 50% for private entities, 90% for public entities) in landholders with qualifying land holdings, with linked entity provisions that trace interests through multiple layers of corporate ownership. These provisions expressly apply to foreign companies and can capture indirect change-of-control events occurring overseas.

Australia does not permit the use of global formulary apportionment to determine the income of foreign-owned local affiliates selling goods or providing services. The Australian taxation system applies the arm’s length principle under the domestic transfer pricing rules, which requires the substitution of arm’s length conditions for actual conditions in cross-border dealings.

While the ATO explicitly rejects predetermined formulary allocation methods, limited exceptions exist for case-specific formulas developed through advance pricing arrangements that take into account particular facts and circumstances.

Country-by-country reporting requirements serve only as risk assessment tools and do not involve formulas for determining taxable income.

Australian resident companies claiming deductions for management and administrative expenses paid to foreign affiliated entities must satisfy the arm’s length principle under Australia’s transfer pricing rules.

Deductions are initially tested under the ordinarily deductibility provision, but where the service charge exceeds arm’s length consideration, the deduction is reduced pursuant to the domestic transfer pricing rules. The applicable standard requires that the consideration paid reflect what independent parties dealing at arm’s length would reasonably be expected to agree upon in comparable circumstances, with arm’s length conditions identified consistently with the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations.

Foreign-owned Australian affiliates face three principal taxation constraints on related-party borrowing from non-local affiliates:

• transfer pricing provisions, which require interest rates and loan terms to reflect arm’s length consideration including security and covenants;
• thin capitalisation rules, which limit interest deductions where the debt-to-equity ratio exceeds 30%; and
• withholding tax obligations, which impose a 10% tax on interest payments to non-resident lenders.

These rules operate successively rather than as mutually exclusive regimes, with the thin capitalisation rules not preventing the application of transfer pricing adjustments.

Foreign income of Australian resident companies is not exempt from corporate tax since Australian resident companies are taxed on their worldwide income from all sources, whether in or out of Australia. However, Australia provides relief from double taxation through foreign income tax offsets, and specific exemptions apply to foreign branch profits.

Local expenses of Australian companies are generally treated as non-deductible to the extent that they are attributable to exempt foreign income or non-assessable non-exempt foreign income. The tax code expressly prohibits deductions for losses or outgoings incurred in relation to gaining or producing exempt income or non-assessable non-exempt income. Where expenses relate to both assessable and exempt income, apportionment is required. A narrow exception exists for debt interest costs incurred in deriving certain foreign non-assessable non-exempt income in the thin capitalisation context.

Dividends from foreign subsidiaries received by Australian corporations are generally not assessable income if they constitute non-portfolio dividends (requiring at least 10% voting interest) paid by non-resident companies to Australian resident companies not acting as trustees. However, where the foreign subsidiary is a controlled foreign corporation (CFC), attributable income may be taxed immediately under Australia’s CFC rules, with relief from double taxation when such attributed income is subsequently distributed as dividends.

Intangibles developed by Australian corporations cannot be used by foreign subsidiaries without incurring Australian tax consequences. Transfer pricing provisions require that any transfer or licensing of intangibles to foreign subsidiaries occur at the arm’s length consideration that independent parties would reasonably expect.

Additionally, royalty withholding tax applies at rates of between 5% and 30% on gross payments for the use of intangible property by non-resident entities.

The ATO applies a risk-based compliance framework through its public guidelines to assess intangibles migration arrangements, with higher-risk arrangements subject to audit and potential application of the general anti-avoidance rule.

Australian companies are taxed on the income of their non-local subsidiaries as earned under Australia’s CFC rules. The assessable income of an attributable taxpayer includes their attribution percentage of a CFC’s attributable income for the statutory accounting period, operating on an accruals basis even when income is not distributed.

The position is fundamentally different for non-local branches of Australian companies. In this case, a branch profits exemption is available, treating active foreign branch income as non-assessable non-exempt income, provided the branch carries on business at or through a permanent establishment and passes the active income test.

Both regimes target passive or tainted income, but foreign subsidiaries face attribution while foreign branches receive exemption for genuine active business operations.

Australia applies substance-related rules to the taxation of foreign income derived by Australian companies through controlled foreign affiliates. The primary mechanism is the active income test, which requires CFCs to carry on business through a permanent establishment in their country of residence. Where a CFC fails this test, passive income and other tainted income categories are attributed to Australian resident controllers on an accruals basis. These rules focus on the actual business activities and nature of income earned by foreign affiliates rather than formal legal structures.

Australian resident companies are subject to CGT on their worldwide assets, including gains from the disposal of shares in foreign affiliates.

When an Australian company disposes of shares in a foreign resident company, CGT event A1 occurs, triggering a capital gain if the capital proceeds exceed the cost base. However, a participation exemption may be available which reduces the capital gain or loss by the active foreign business asset percentage of the foreign company. To qualify for this exemption, the Australian company must hold at least a 10% direct voting interest in the foreign company for a continuous 12-month period ending at or before the disposal, and the shares must not be finance shares.

Companies, unlike individuals, cannot access the 50% CGT discount and must include the full amount of any net capital gain in their assessable income.

Australian companies deriving foreign income are subject to multiple overlapping anti-avoidance provisions designed to protect the Australian tax base.

The general anti-avoidance rule in the income tax law, GST law, and state and territory taxation law applies to schemes where there is a tax benefit obtained with a dominant purpose of tax avoidance.

Specific anti-avoidance regimes target particular risks:

• transfer pricing rules;
• CFC rules attribute passive foreign income to Australian controllers to prevent tax deferral in low-tax jurisdictions; and
• thin capitalisation provisions under Division 820 limit excessive interest deductions on foreign debt – see Consolidated Press Holdings Ltd v Commissioner of Taxation (Cth) (1998) 88 FCR 151, Commissioner of Taxation v Consolidated Press Holdings Ltd (1999) 91 FCR 574.

Recent additions include the diverted profits tax at 40% targeting multinational profit shifting through royalty and similar arrangements.

Australia does not have a single routine audit cycle applicable to all entities. Instead, the Australian regulatory framework prescribes annual audit cycles tailored to different entity types under sector-specific legislation.

Public companies and registered schemes must have their financial reports audited annually, and must appoint or ratify their auditors at each annual general meeting.

Self-managed superannuation funds must appoint approved auditors for each income year.

Public sector entities undergo annual financial audits conducted by the Auditor-General, with performance audits undertaken on a discretionary basis according to published work programmes.

Australia has comprehensively implemented the OECD’s Base Erosion and Profit Shifting (BEPS) recommendations through a combination of domestic legislation and treaty modifications.

Key measures include:

• the Multinational Anti-Avoidance Law (MAAL), effective from 1 January 2016, which seeks to redress schemes that limit a taxable presence in Australia;
• the diverted profits tax at 40%;
• hybrid mismatch rules, effective from January 1st;
• country-by-country reporting requirements for entities with global income exceeding AUD1 billion, effective from 1 January 2016; and
• the Multilateral Instrument (MLI), which entered into force for Australia on 1 January 2019 to modify most of Australia’s tax treaties.

Australia has been a consistent and proactive supporter of the OECD BEPS project across successive governments, driven by the policy objective of ensuring that multinationals pay their “fair share” of tax, protecting the revenue base, and levelling the playing field for domestic businesses.

Pillar Two

Pillar Two has been fully enacted, with primary legislation receiving royal assent on 10 December 2024 and subordinate computational rules registered on 23 December 2024. The Income Inclusion Rule and Domestic Minimum Tax apply from 1 January 2024. The Undertaxed Profits Rule applies from 1 January 2025. First returns are due 30 June 2026.  All multinational enterprise (MNE) groups with consolidated revenue exceeding EUR750 million are in scope.

Pillar One

Pillar One remains uncertain globally. The Amount A Multilateral Convention cannot enter into force without US ratification, which the Trump administration has explicitly repudiated. Australian implementation is therefore indefinitely deferred.

The greatest practical impact will fall on inbound MNEs with low-taxed Australian profits, Australian-headquartered outbound groups in resources and finance, and structures reliant on intellectual property holding or related-party financing arrangements in low-tax jurisdictions.

International tax has a distinctly high public profile in Australia, and this has materially accelerated BEPS implementation locally.

The cultural, political and economic settings in Australia mean that tax performance of big business is a community issue that attracts significant political and media interest. Australia has a strong cultural ethos that emphasises the importance of fairness and integrity. Moreover, the ATO publishes an annual corporate tax transparency report informing public debate about the corporate tax system.

Public country-by-country reporting legislation passed by the Australian Parliament requires large multinationals to publicly report taxes paid, profits and employee numbers across a broad list of jurisdictions.

The Australian government considers the impact of foreign investment proposals on tax revenues and ensures that investments align with its objectives, including environmental and economic considerations. Taxation is a factor in foreign direct investment decisions, but it is not the most critical determinant.

The sensitivity of foreign direct investment to taxation depends on host country conditions, corporate tax rates, and other factors. Application fees for foreign investment are assessed to balance compliance costs and preserve Australia’s investment appeal, with fees set below 1% of the investment value to minimise behavioural impacts on investment decisions.

Australia’s international tax rules have evolved to counter tax avoidance and minimise opportunities for tax-driven offshore investments. The deregulation of the Australian dollar and the movement of capital have historically encouraged investments in low-tax jurisdictions, prompting legislative changes to address these issues. The Commissioner has broad powers to obtain information and evidence for the administration of taxation laws, ensuring compliance and addressing tax avoidance.

Australian courts have also addressed issues related to international tax agreements and the allocation of taxing rights between Australia and other countries, ensuring that domestic provisions align with bilateral agreements.

A competitive tax system is characterised by features such as low corporate tax rates, generous tax concessions, flexible transfer pricing rules, and the presence of DTAs that facilitate cross-border business activities.

These features, while attractive for investment, can make the system more vulnerable to BEPS-related risks, including profit shifting, tax avoidance, and erosion of the domestic tax base. For example, the existence of MAPs and reliance on OECD Model Convention principles, as discussed in judicial interpretation, can create opportunities for taxpayers to exploit mismatches between jurisdictions, especially where definitions of income, royalties and permanent establishment are not harmonised or are interpreted flexibly.

The vulnerability arises because competitive tax systems often seek to attract MNEs by offering incentives or by not imposing strict anti-avoidance measures. This can lead to situations where profits are shifted to jurisdictions with lower tax rates or more favourable tax treatment, thereby reducing the effective tax paid in Australia. The use of transfer pricing guidelines and the implementation of the MLI are intended to mitigate these risks, but their effectiveness depends on the robustness of domestic legislation and the consistency of international treaty interpretation.

Regarding constraints such as state aid, Australia does not have a formal state aid regime akin to that of the European Union. However, there are constitutional constraints on discrimination and preference in taxation laws. These provisions prohibit the Commonwealth from enacting laws that discriminate between states or give preference to one state over another in matters of taxation or revenue.

The High Court has clarified that differential treatment or unequal outcomes are not necessarily unconstitutional unless they are the result of distinctions based on state boundaries or are not appropriate and adapted to a proper objective. Thus, while there are no state aid rules per se, there are significant constitutional limitations on the Commonwealth’s ability to favour particular regions or industries through tax measures.

Australia has implemented legislative measures to address the tax challenges posed by hybrid instruments, particularly in response to the OECD’s BEPS Action Plan. Hybrid mismatch rules have been enacted to neutralise tax advantages arising from hybrid arrangements.

The hybrid mismatch rules aim to address mismatches that result in double non-taxation or double deductions. These rules apply to various types of hybrid mismatches, including hybrid financial instrument mismatches, hybrid payer mismatches, reverse hybrid mismatches, branch hybrid mismatches and imported hybrid mismatches. The legislation ensures that such mismatches are neutralised by either denying deductions or including amounts in assessable income, depending on the circumstances.

The hybrid financial instrument mismatch rules, for instance, target situations where a financial instrument is treated differently for tax purposes in Australia and a foreign jurisdiction, leading to a deduction/non-inclusion outcome. These rules also include an integrity provision to address payments made in lieu of hybrid payments and extend to payments subject to concessional tax rates in foreign countries.

The branch hybrid mismatch rules address mismatches arising from payments made to or by a branch hybrid, which is an entity treated as a branch in one jurisdiction and as a separate entity in another. These rules ensure that such payments are appropriately taxed either in Australia or the foreign jurisdiction.

The reverse hybrid mismatch rules deal with payments made to reverse hybrids, which are entities treated as transparent in their jurisdiction of establishment but as separate entities in the investor’s jurisdiction. These rules aim to prevent deduction/non-inclusion mismatches by assuming that the payment was made directly to the investing taxpayer.

The implementation of these rules aligns with the BEPS Action 2 recommendations, which focus on neutralising the effects of hybrid mismatch arrangements. The rules apply to income years starting on or after 1 January 2019.

These legislative developments demonstrate Australia’s commitment to addressing the challenges posed by hybrid instruments and aligning its tax system with international standards to combat BEPS.

Australia does not have a territorial tax regime. Instead, it operates on a worldwide taxation system for Australian residents, meaning that Australian residents are taxed on their global income, while non-residents are taxed only on their Australian-sourced income.

Double taxation conventions (DTCs) play a critical role in determining the tax obligations of both inbound and outbound investors in Australia. These agreements aim to prevent double taxation and fiscal evasion by allocating taxing rights between Australia and its treaty partners. However, limitations on benefits (LOB) provisions and anti-avoidance rules within DTCs can significantly impact investors.

LOB provisions are designed to prevent treaty shopping, where entities attempt to exploit DTCs by routing income through jurisdictions with favourable tax treaties.

Anti-avoidance rules, such as the general anti-avoidance rule, are designed to counteract schemes that aim to obtain tax benefits in a manner inconsistent with the intent of the law. These rules apply to both inbound and outbound investors. For instance, the general anti-avoidance provisions may strike down tax benefits arising from schemes with a dominant purpose of tax avoidance. Additionally, the MAAL and DPT target significant global entities to ensure that profits made in Australia are appropriately taxed. The DPT imposes a 40% tax on diverted profits and aims to prevent the use of artificial arrangements to limit the attribution of profits to Australia.

The BEPS initiative has significantly influenced Australia’s transfer pricing framework, particularly in the context of intellectual property taxation. The changes aim to align Australia’s tax laws with international standards, ensuring that profits are taxed where economic activities and value creation occur.

Australia’s transfer pricing provisions ensure that cross-border transactions, including those involving intellectual property, adhere to the arm’s length principle. This principle requires that transactions between related parties be conducted as if they were between independent entities, ensuring that profits are not artificially shifted to low-tax jurisdictions.

Recent high-profile litigations such as Chevron and Glencore underscore the need for robust documentation and compliance with transfer pricing rules, particularly for transactions involving intellectual property, where valuation can be complex and subjective, and the necessity of basing transfer pricing adjustments on the actual transactions entered into by the parties, provided they are commercially rational. This principle is particularly relevant for intellectual property transactions, where the valuation of royalties, licencing fees and other payments can be contentious.

As mentioned previously, Australia has also introduced the DPT in its general anti-avoidance provisions, which has the effect that it cannot be overridden by tax treaties.

Australia has comprehensively implemented the BEPS transparency framework, with particular emphasis on country-by-country (CbC) reporting under Action 13. Introduced through the Multinational Anti-Avoidance Law on 11 December 2015 and applying from 1 January 2016, the framework adopts the OECD’s three-tier documentation approach, requiring Significant Global Entities (SGEs) – being those groups with annual global income of AUD1 billion or more – to lodge a CbC Report, Master File and Local File within 12 months of the relevant reporting period.

Australia has aligned its CbC reporting requirements directly with the OECD’s Action 13 guidance, adopting Annex III for the CbC Report and Annex I for the Master File. From June 2018, Australia began exchanging CbC reports with partner jurisdictions, contributing to the global minimum standard under which approximately 120 jurisdictions now have CbC obligations in place.

Transparency has been further enhanced through public CbC reporting, effective for periods commencing 1 July 2024, drawing on the GRI 207: Tax 2019 standard to enable public assessment of whether an entity’s economic presence aligns with taxes paid. Separately, under Action 5, Australia has exchanged information on six categories of tax rulings since April 2016, governed by treaty confidentiality provisions.

Most recently, the ATO expanded its short-form Local File requirements in 2024, targeting a broader range of risks beyond transfer pricing, including hybrid mismatches, withholding tax and anti-avoidance provisions, reflecting Australia’s ongoing commitment to robust and evolving BEPS compliance.

Australia has addressed digital economy taxation through several BEPS measures rather than a standalone Digital Services Tax (DST). GST at 10% has applied to digital services supplied by non-resident providers since 1 July 2017. More significantly, Pillar Two legislation received assent on 10 December 2024, imposing a 15% global minimum effective tax rate on MNE groups with consolidated revenue exceeding EUR750 million, through an Income Inclusion Rule, Undertaxed Profits Rule, and Domestic Minimum Tax.

Pillar One, which would reallocate taxing rights to market jurisdictions and supersede unilateral DSTs, remains under negotiation. The OECD’s January 2025 statement confirmed progress but acknowledged that consensus on the Multilateral Convention has not yet been reached.

A traditional DST has been proposed and analysed by the Parliamentary Budget Office, which estimated revenue of AUD3 billion over the forward estimates period, drawing on UK and Canadian models. However, implementation remains uncertain, complicated by the USA withdrawing from OECD negotiations and naming Australia in its February 2025 review of DST retaliatory tariffs.

Australia’s current approach favours multilateral co-ordination over unilateral measures, while continuing to strengthen anti-avoidance provisions, including revised thin capitalisation rules applying from 1 July 2023.

In addition to the Pillar Two and GST measures discussed previously, Australia’s broader position on digital taxation reflects a deliberate preference for multilateral co-ordination over unilateral action. Both major parties have firmly opposed a standalone DST, partly due to US trade policy concerns. The Trump administration specifically named Australia in its February 2025 review of DST retaliatory tariffs. Nevertheless, the Parliamentary Budget Office has analysed a proposed 3% DST on Australian gross revenue exceeding AUD20 million, projecting AUD3 billion over the forward estimates period. That proposal remains unimplemented, with Australia continuing to favour the OECD framework.

Australia’s framework for taxing offshore intellectual property deployed domestically operates primarily through withholding tax rather than direct assessment. The default rate is 30% on royalties paid to non-residents, reduced to 5–10% for intellectual property owners in countries with which Australia has one of its 45+ DTAs. Treaty residents who carry on business through an Australian permanent establishment are instead directly assessed on royalty income.

Recent enforcement measures have significantly strengthened this framework. Draft Taxation Ruling TR 2024/D1 broadens the characterisation of software payments as royalties, the High Court’s PepsiCo decision confirmed that withholding tax applies to embedded royalty components in commercial arrangements, and from 1 July 2026 SGEs face new penalties for mischaracterising or undervaluing royalty payments. Proposed deduction denial rules targeting intellectual property held in low-tax jurisdictions were withdrawn, with the Pillar Two domestic minimum tax considered sufficient to address that mischief.
