Below, we highlight updated rules, practical examples, and expert insights to guide you through October tax planning in Australia.

October 2025 Tax Planning: What Every Australian Should Consider

Reviewing Superannuation Contributions Before Year-End

Superannuation remains one of the most tax-effective ways to plan for retirement while reducing taxable income. For 2025, concessional contributions are capped at $30,000 annually. Salary sacrifice arrangements allow employees to contribute pre-tax income into super, taxed at just 15%, instead of their marginal rate. Making additional voluntary contributions before June 30 can provide significant tax savings.

For self-employed Australians, the same concessional contribution limits apply, with deductions claimed directly on the annual tax return. The Australian Taxation Office (ATO) encourages individuals to keep records of contributions through MyGov or fund statements to ensure compliance.

Experience: A Melbourne IT consultant shared that making an extra $10,000 salary sacrifice into super saved them over $3,000 in tax while boosting retirement savings.

Using Tax Offsets and Rebates Available in 2025

Tax offsets and rebates remain an underutilised strategy for many Australians. The Low and Middle Income Tax Offset (LMITO) ended in previous years, but other credits such as the Seniors and Pensioners Tax Offset (SAPTO) remain in place. Families can also benefit from offsets tied to private health insurance and childcare expenses.

Businesses may still claim small business tax offsets if their aggregated turnover is under $5 million. This offset reduces tax payable by up to $1,000 annually, depending on business income.

In addition, energy efficiency rebates tied to home solar installation and electric vehicle purchases remain available in certain states, providing both tax and cost-of-living relief.

Insight: Accountants recommend reviewing state-level rebates in New South Wales, Victoria, and Queensland, as they can add to federal incentives for maximum benefit.

💡 How Can Businesses Optimise Deductions in October 2025?

Businesses in Australia have several strategies to reduce taxable income before year-end. Immediate asset write-offs for eligible equipment purchases remain a major incentive, though thresholds vary. Reviewing expense categories such as travel, staff training, and professional fees can also unlock deductions.

Another key strategy is prepaying certain expenses, such as rent, insurance, or software subscriptions, which allows businesses to bring forward tax deductions into the current year. This can be especially effective for businesses expecting higher income this financial year compared to the next.

Experience: A small café in Sydney reduced taxable income by $15,000 by prepaying supplier contracts and equipment leases, giving them a stronger cash flow outlook.

Comparing Tax Strategies for Individuals vs Businesses

While individuals focus more on super contributions, deductions, and offsets, businesses benefit from depreciation schedules, asset write-offs, and GST credits. Both groups, however, gain from careful recordkeeping and timely tax planning.

Insight: Accountants often advise blending both federal and state-level strategies for maximum impact, especially for dual-income households and SMEs.

👀 Should You Rebalance Investments Before Year-End?

October is a key month for investors to rebalance portfolios before the financial year-end approaches. Realising capital losses on underperforming shares can offset capital gains, reducing tax payable. Many Australians use ETFs and managed funds for diversification, but actively reviewing allocations ensures risk and tax efficiency.

Franking credits on Australian shares continue to provide valuable tax benefits, especially for retirees. Selling shares strategically before June 30 can help align tax outcomes with broader financial goals.

Experience: An investor in Brisbane reduced taxable capital gains by offsetting $8,000 worth of share losses against gains made in the property market.

Common Tax Planning Mistakes to Avoid

Many Australians miss out on deductions by failing to keep receipts or misunderstanding eligibility. Another common mistake is not reviewing super contribution limits, which can result in excess contribution penalties. Businesses often overlook prepaid expense rules or misclassify assets, leading to compliance risks.

The ATO provides clear guidance, but consulting a registered tax agent can ensure strategies are applied correctly. Inconsistent recordkeeping remains one of the top red flags for audits in 2025.

Experience: A Perth family shared that simply consolidating their deductions with a tax agent boosted their refund by $2,500, highlighting the value of professional advice.

• Maximise superannuation contributions before June 30.
• Claim available offsets such as SAPTO and business tax rebates.
