EOFY 2026 Tax Planning Checklist for Australian Business Owners

30 June 2026 is almost here — are you prepared? As a business owner, you have a lot to action before your financial year closes. From paying your superannuation on time and claiming the $20,000 instant asset write-off, to writing off your bad debts, scrapping your unused equipment, prepaying eligible expenses, and preparing for the Payday Super transition starting 1 July 2026 — every step matters and every deadline counts. Missing just one of these could mean losing thousands in legitimate tax deductions, or worse, triggering an ATO audit on your business. The ATO\'s data-matching capabilities are more advanced than ever in 2026, automatically cross-referencing your bank data, your industry benchmarks, and your business activity statements to flag inconsistencies. The good news? A little planning now goes a long way for your business. Reviewing your asset register, documenting your staff bonuses, maximising your concessional super contributions, and managing your capital gains before year-end can make a significant difference to your final tax bill. We\'ve put together a comprehensive, step-by-step EOFY 2026 Tax Planning Checklist on our website and it covers everything you need to stay compliant, maximise your deductions, and go into your new financial year with complete confidence.
