The latest Australian tax rates for 2026 determine how much money you actually keep and help you make better financial decisions. Even small changes to the tax brackets can influence how you handle investments or think about expanding.

In this guide, we’ll explain the current Australian tax rate in 2026, highlight what’s changed, discuss how it affects business owners, and share practical tax planning strategies to help reduce your tax while staying compliant.

Current Australian Tax Rates in 2026 for Individuals and Businesses

For Australian residents (including sole traders), the tax brackets for the 2025–26 and 2026–27 income years are:

These rates do not include the 2% Medicare Levy.

Sole traders and partnerships pay tax at these individual rates on their business profits after eligible deductions.

Companies continue to pay tax at flat rates:

• 25% for base rate entities.
• 30% for all other companies.

A business qualifies as a base rate entity if:

• Aggregated turnover is under $50 million, and
• No more than 80% of its income is passive income (such as rent, interest, or dividends).

These company tax rates have remained unchanged since the 2021–22 financial year.

Key Updates and Changes in 2026 and Beyond

The Australian tax rate in 2026 introduces the next phase of the Stage 3 tax cuts, along with several measures announced in the 2026–27 Federal Budget.

From 1 July 2026, the tax rate for income between $18,201 and $45,000 falls from 16% to 15%. It is scheduled to reduce further to 14% from 1 July 2027.

For taxpayers earning more than $45,000, these changes are expected to provide annual tax savings of approximately:

• Around $268 in 2026–27.
• Around $536 per year from 2027–28 onwards.

Other key Budget announcements include:

• Permanent $20,000 instant asset write-off for eligible small businesses (turnover under $10 million) from 1 July 2026.
• Permanent two-year loss carry-back for companies with turnover up to $1 billion from 2026–27.
• Loss refundability for eligible start-ups beginning in 2028–29.
• A new $250 Working Australians Tax Offset from 2027–28 for eligible workers, including sole traders.

Important: These Budget measures have been announced but are not yet legislated. Always confirm their status with a qualified tax adviser before making business decisions.

The Treasury Laws Amendment (Tax Reform No. 1) Act 2026, which received Royal Assent on 26 June 2026, also introduces major reforms for property investors and businesses with significant assets.

From 1 July 2027:

• The 50% Capital Gains Tax (CGT) discount for individuals, trusts, and partnerships will be replaced with cost base indexation and a 30% minimum tax rate on capital gains.
• Negative gearing on residential property investments will be limited to new builds only.

Impact on Business Owners

The Australian tax rate in 2026 directly influences your cash flow, investment decisions, and overall business profitability.

Lower tax rates on the first $45,000 of taxable income mean sole traders and business owners who receive wages will retain more of their income. Companies also continue to benefit from the relatively low 25% or 30% company tax rates, which are generally lower than the highest individual tax rate of 45% (plus Medicare Levy).

Positive Impacts

• Improved deductions and loss offsets provide additional cash flow for small and medium businesses.
• The permanent instant asset write-off encourages investment in equipment and business growth.
• Loss carry-back provisions offer valuable support during difficult trading periods.

Challenges

• Bracket creep remains an issue. As wages rise without matching tax threshold increases, more income may be taxed at higher rates.
• Businesses earning significant passive income could lose access to the 25% company tax rate if passive income exceeds 80%.
• High-income business owners earning above $190,000 continue to pay the top marginal tax rate, making strategies such as additional super contributions or business restructuring worth considering.

Overall, the changes create new opportunities, but careful planning remains essential.

Smart Tax Planning Strategies for Business Owners

Effective tax planning should be a year-round activity rather than something left until June.

Consider the following strategies:

Choose the Right Business Structure

Review whether remaining a sole trader or operating through a company is the most tax-effective option. Companies may offer lower tax rates and greater asset protection but also have additional compliance obligations.

Maximise Available Deductions

Take advantage of available deductions by:

• Using the $20,000 instant asset write-off where eligible.
• Prepaying allowable business expenses.
• Exploring Research and Development (R&D) tax incentives.
• Maintaining accurate financial records throughout the year.

Make Super Contributions

Additional concessional super contributions may reduce taxable income while helping build retirement savings.

Time Income and Expenses Carefully

Where appropriate, consider:

• Deferring income into the next financial year.
• Bringing forward deductible expenses.
• Making use of company loss carry-back provisions where available.

Australian tax legislation can become complex quickly. Seeking professional advice can help ensure you claim every available deduction while remaining compliant.
