New year, new tax obligations. For Australian business owners, 2026 brings updated ATO compliance requirements, new thresholds, and fresh opportunities to reduce your tax bill. Here are five business tax resolutions every Australian SME should commit to in 2026.
1. Confirm Your Business Status With the ATO
The ATO distinguishes between a genuine business and a hobby based on commercial intent, profit expectation, scale, and repetition. If you earn income from a side activity without a genuine profit motive, the ATO may treat it as a hobby, meaning no deductions apply. In 2026, the ATO is increasing scrutiny of online selling, gig economy income, and digital services. Document your business intentions clearly.
2. Keep Impeccable Records All Year
The ATO requires businesses to retain records for a minimum of 5 years from when you lodge your return. Cloud-based accounting software such as Xero, MYOB, or QuickBooks makes this easier than ever. Reconcile your accounts monthly, not just at EOFY, to avoid costly catch-up work and potential audit exposure.
- Retain all invoices, receipts, and bank statements
- Use separate business and personal bank accounts
- Record the business purpose of every expense over $82.50
- Log all vehicle kilometres with a compliant ATO logbook
3. Maximise the $20,000 Instant Asset Write-Off
The instant asset write-off threshold of $20,000 per asset is now permanent for small businesses with turnover under $10 million. Purchasing eligible depreciating assets before 30 June 2026 allows you to claim the full cost as an immediate deduction rather than depreciating over years. This is one of the most powerful cash-flow strategies available to Australian SMEs.
4. Pay Super on Time Every Quarter
Super Guarantee (SG) payments at 12% of ordinary time earnings must reach employees' super funds by the quarterly due dates. Missing a deadline triggers the Super Guarantee Charge (SGC), a non-deductible penalty including the unpaid SG, 10% interest, and an administration fee. Automate super payments through your payroll software in 2026.
5. Plan Your Tax Before 30 June 2026
Tax planning is most effective before the end of the financial year. Before 30 June 2026, review your profit-and-loss position, potential income deferral or expense pre-payment opportunities, director fees or trust distributions, and whether a tax agent is managing your ATO correspondence proactively.
Frequently Asked Questions

Who qualifies for the $20,000 instant asset write-off in 2026?
Businesses with aggregated annual turnover below $10 million qualify. The asset must be first used or installed ready for use between 1 July 2025 and 30 June 2026. Each asset is assessed individually with no cap on the number of assets claimed.
