Chloe KennedyAustralia's Federal Budget 2026-27, delivered by Treasurer Jim Chalmers on 12 May 2026, landed four changes that every small business owner should act on before 30 June. The $20,000 instant asset write-off is now permanent. R&D tax incentives are expanding. CGT rules are changing in ways that will affect anyone selling a business or investment property from July 2027. And a new $1,000 instant deduction for individuals requires no receipts and no itemisation.
These aren't talking points. They are live legislative changes with specific eligibility conditions and strict deadlines that determine whether you benefit or miss out.
The $20,000 Instant Asset Write-Off: Now Permanent
For the past several years, the instant asset write-off has operated as a temporary measure — extended budget by budget, creating uncertainty for business planning. Budget 2026 changes that permanently for eligible businesses with annual turnover under $10 million.
From 1 July 2026, those businesses can immediately deduct the full cost of eligible assets costing up to $20,000 against taxable income in the year of purchase, rather than depreciating the cost over multiple years. This has a direct and measurable impact on cash flow and tax payable.
The key word is "eligible." Not all assets qualify, and the timing of when an asset is "first used or installed ready for use" determines which income year the deduction falls in. A vehicle purchased in late June 2026 but not registered or available until July will fall into the 2026-27 year, not 2025-26. A tax adviser can help structure the timing of capital purchases to maximise the benefit within the right income year.
R&D Tax Incentive: Major Expansion From July 2028
For tech businesses, startups, and companies conducting eligible research and development, the budget delivers a significant restructure taking effect from 1 July 2028. The core R&D offset rate rises by approximately 4.5 percentage points (to approximately 48%). The refundable offset turnover threshold jumps from $20 million to $50 million, bringing more mid-size companies into eligibility.
The maximum R&D expenditure cap also rises from $150 million to $200 million, and the minimum spend threshold moves from $20,000 to $50,000 — meaning smaller experimental claims no longer qualify, while larger operations gain headroom.
According to the Australian Taxation Office, the R&D Tax Incentive is one of the most complex areas of Australian tax law, with strict requirements around "core" vs "supporting" R&D activities, record-keeping, and registration timelines. Claiming incorrectly — or failing to register by the 30 April deadline following the income year — can result in complete loss of the entitlement.
If your business conducts any activity that could meet the R&D definition, a qualified tax specialist should assess your eligibility before the next income year begins.
CGT Reform: Timing Matters for Business Owners
The capital gains tax changes announced in Budget 2026 take effect from 1 July 2027 — giving business owners and investors just over one year to assess their position. The 50% CGT discount for individuals holding assets longer than 12 months will be replaced by a cost-base indexation system combined with a 30% minimum tax on net capital gains.
For many small business owners planning an exit, the timing of a sale around this threshold will have a significant financial impact. The difference between completing a business sale in June 2027 versus July 2027 could be measured in tens of thousands of dollars depending on the gain size.
This is also relevant for investment property owners who have relied on the 50% discount as a retirement planning tool. As explored in the 2026 budget's impact on Australia's middle class, the changes reshape how capital gains feed into broader financial planning strategies.
The $1,000 Instant Work Deduction
For individuals, Budget 2026 introduces a $1,000 standard work-related deduction, available from 1 July 2026 without receipts. This replaces the old system where small work-related claims required documentation and itemisation.
For employees, this means most standard work deduction claims under $1,000 are now simpler. For those with legitimate work-related expenses above $1,000 — home office claims, professional development, tools, and equipment — the standard rules and documentation requirements continue to apply for the excess amount.
The interaction with salary packaging arrangements requires care. Some packaging agreements may affect how the deduction applies. A tax accountant can confirm the correct treatment for your specific situation.
Act Before 30 June — Not After
Budget measures create a specific problem that many Australian small business owners face year after year: the changes are announced in May and take effect in July, leaving a narrow window for tax planning before the financial year closes.
The businesses that benefit most from measures like permanent instant asset write-offs are those who know their eligibility conditions, understand their income year timing, and have professional support to act decisively. An ExpertZoom accountant or tax adviser can provide a structured review of your 2025-26 position and your readiness for the changes taking effect from 1 July 2026.
