If you run a business in Australia, “big tax changes are coming” is a warning you’ve heard before. This year, it’s real. The Australian tax changes 2026 touch payroll timing, income tax brackets, asset deductions, and how capital gains will eventually be taxed, and relying on last year’s settings is no longer safe.
Here’s a clear rundown of the ATO updates 2026 business owners need on their radar, what’s already law, and what to do about it.
What Are the Biggest Tax Changes for Australian Businesses in 2026?
Several changes deserve immediate attention as part of the broader business tax changes Australia 2026 brings:
- Payday Super commenced from 1 July 2026, and super must reach an employee’s fund within 7 business days of each payday, not quarterly.
- The super guarantee rate holds at 12%, now the permanent, final rate.
- Concessional super caps rose to $32,500, with flow-on increases elsewhere.
- The 15% income tax rate now applies on earnings between $18,201–$45,000 (down from 16%).
- Company tax is unchanged: 25% for base rate entities, 30% for others.
- The $20,000 instant asset write-off is now permanent for eligible small businesses, effective 1 July 2026; Parliament passed this into law on 19 August 2026.
- A permanent two-year loss carry-back regime for eligible companies also passed into law on 19 August 2026.
These small business tax changes Australia has introduced this year are some of the most consequential in over a decade, so it’s worth working through each one properly.
Payday Super: The Biggest Shift for Employers
Payday Super Australia is arguably the single most significant operational change on this list. As of 1 July 2026, employer super contributions must generally land in an employee’s fund within seven business days of payday, replacing the old 28-days-after-quarter-end rule.
This removes a cash flow buffer many businesses were quietly relying on, and it raises the compliance stakes: missing the window can trigger the non-deductible Superannuation Guarantee Charge, plus interest and a per-employee admin fee.
Check now:
- Does your payroll software process super within the 7-day window automatically?
- Do you have a SuperStream-compliant clearing house? (The ATO’s Small Business Clearing House has closed.)
- Are cash flow forecasts built around weekly/fortnightly super outflows, not one quarterly lump sum?
Has the Super Guarantee Rate Changed in 2026?
No. It reached 12% of ordinary time earnings from 1 July 2025, and there’s no further legislated increase. What changed is when you pay it via Payday Super, not the rate itself.
Contribution caps did move for 2026–27, which matters for Australian tax compliance 2026 if you or your staff are making additional contributions:
| Cap | 2026–27 Amount |
| Concessional (pre-tax) contribution cap | $32,500 |
| Non-concessional (after-tax) contribution cap | $130,000 |
| Bring-forward cap (3 years) | $390,000 |
| General transfer balance cap | $2.1 million |
| Division 293 threshold | $250,000 (unchanged) |
The New Income Tax Rate for 2026
The $18,201–$45,000 bracket dropped from 16% to 15% from 1 July 2026 (falling again to 14% from 1 July 2027). For business owners, this affects two things:
- PAYG withholding accuracy for staff on lower incomes
- How much sole traders and partners keep from distributed profit
Make sure your payroll software has been updated to reflect this new rate. If it hasn’t, you risk either withholding too much or too little tax from employee pay. Both create extra reconciliation work later. This is also a good time to revisit your tax planning Australia 2026 strategy, particularly if you distribute profit to individuals.
The $20,000 Instant Asset Write-Off is Now Permanent
Parliament passed the Treasury Laws Amendment (Tax Reform No. 2) Bill 2026 on 19 August 2026, making the $20,000 instant asset write-off permanent. No more year-by-year renewal, and no more uncertainty about whether it will survive the next Budget.
Eligible businesses with aggregated annual turnover below $10 million can immediately deduct the business-use portion of qualifying depreciating assets costing less than $20,000 each, provided the asset is first used or installed ready for use for a taxable purpose from 1 July 2026 onward.
Depending on the circumstances, this could include:
- Computers and technology
- Tools and equipment
- Machinery
- Office equipment
- Other eligible business assets
The threshold applies on a per-asset basis, so multiple eligible purchases in the same year can all qualify. Assets costing $20,000 or more still go into the small business depreciation pool, written off at 15% in the first income year and 30% each year after.
Tax Loss Carry-Back Returns for Eligible Companies
The same Bill that made the instant asset write-off permanent also locked in a permanent two-year loss carry-back regime for eligible corporate tax entities, for income years starting from 1 July 2026.
In practice, this means a company that has paid tax in a previous profitable year and then experiences a loss may be able to carry that loss back against profits from up to two earlier income years, generating a refundable tax offset, subject to eligibility rules and the entity’s franking account balance. This can be particularly useful for businesses investing heavily in growth, recovering from a downturn, or managing a temporary dip in profitability.
GST, BAS Reporting Changes and What the ATO Is Watching
GST compliance Australia wide now runs on far more automated data matching. Marketplace sales, POS systems, and bank feeds are increasingly checked against your BAS, and the ATO’s reporting requirements are tightening as a result.
Do I need to register for GST? Yes, once turnover reaches (or is likely to reach) $75,000 a year ($150,000 for non-profits); it’s voluntary below that.
Mixed-use expenses (vehicles, phones, home office) remain a common audit trigger when private use isn’t clearly separated, and reconciliation mismatches are picked up faster than before as part of the wider ATO compliance updates rolling out this year. Treat GST as money held on the ATO’s behalf, not working capital.
Capital Gains Tax: What’s Changing (and What Isn’t Yet)
The 50% CGT discount isn’t disappearing this year. Reform legislation has passed, replacing it with CPI cost-base indexation plus a minimum tax on real gains, but it only applies to gains accruing from 1 July 2027 onwards. Existing assets aren’t affected yet, but any decisions about buying, restructuring, or eventually selling appreciating assets should account for the new rules in advance.

What Should Businesses Do Before EOFY?
The best approach to EOFY tax changes Australia businesses face this year is not to wait until June. Before EOFY, run through your core business tax obligations Australia requires and confirm:
- Payroll is Payday Super-ready, including a compliant clearing house.
- PAYG withholding reflects the 15% bracket.
- Super contribution caps are checked against your own and staff contributions.
- The instant asset write-off is applied correctly to any eligible purchases.
- GST is reconciled regularly and kept in a separate account.
- Your business structure is reviewed against the new loss carry-back rules and the future CGT changes.
- Asset registers and expense records are clean and current.
Treat tax compliance for small business as an ongoing habit rather than a once-a-year scramble. This is the single biggest predictor of a smooth EOFY.
