Quick Answer:
Australians commonly miss the Small Business Income Tax Offset (up to $1,000), the Seniors and Pensioners Tax Offset (up to $2,230), and the Private Health Insurance Offset. From 1 July 2026 the bottom individual tax rate also drops from 16% to 15%, and a $1,000 instant work deduction starts from the 2026-27 income year.
Tax offsets reduce your tax bill dollar for dollar. If you are lodging your 2025-26 return now, this is the right time to check you are claiming everything you are entitled to. Unlike tax deductions, which reduce your taxable income, tax offsets reduce the tax you owe directly. That makes them worth checking carefully, especially if you qualify for more than one.
Here are six offsets Australians often miss: the Small Business Income Tax Offset (up to $1,000), the Seniors and Pensioners Tax Offset (up to $2,230), the Private Health Insurance Offset (up to 32.385% of premiums, refundable in 2026), the Zone Tax Offset ($57 to $1,173), and the Invalid and Invalid Carer Offset. From 1 July 2026 the bottom tax rate has also dropped from 16% to 15%, and a $1,000 instant work deduction is legislated to begin from the 2026-27 income year.
1. Small Business Income Tax Offset: The Forgotten $1,000
Maximum benefit: $1,000 per year. Who qualifies: sole traders, and individuals with income from a small business partnership or trust, where the business has an aggregated turnover under $5 million. Calculation: 16% of your net small business income, capped at $1,000.
Example: if your net small business income is $6,250 or more, you get the full $1,000 offset. With $3,000 in business income, you would get a $480 offset.
If you run a business through a company structure rather than as a sole trader, different rules apply. Our guide to small business tax changes for 2026-27 covers rates and concessions at the entity level, and our avoidable business tax mistakes article covers the errors we see most often at tax time.
2. Seniors and Pensioners Tax Offset (SAPTO): Relief for Retirees
Maximum benefit: $2,230 for singles, $1,602 for each member of a couple. Who qualifies: recipients of eligible Australian Government pensions or allowances, including the Age Pension, Disability Support Pension, Carer Payment, and veterans’ pensions and allowances. No application is required; it is calculated automatically if you are eligible.
Income thresholds for 2025-26: singles get the full offset if rebate income is under $34,919, phasing out completely at $52,759; couples get the full offset if each partner’s rebate income is under $30,994, phasing out at $43,810 each; couples separated by illness get the full offset under $33,732, phasing out at $47,599 each. Unused SAPTO can transfer automatically between eligible spouses.
Example: John, 68, receives the Age Pension with $25,000 of rebate income. He gets the full $2,230 SAPTO, which may eliminate his tax liability for the year.
See the ATO’s seniors and pensioners tax offset page for the full thresholds.
3. Private Health Insurance Offset: The Refundable One
Who qualifies: private health insurance holders under the Tier 3 income threshold. This is one of the few refundable offsets, meaning you can get money back even if you do not owe tax. You can take it as reduced premiums throughout the year, or as a refundable offset when you lodge.
Income thresholds and rebate rates for 1 July 2025 to 31 March 2026:
| Tier | Single Income | Family Income | Rebate (under 65) | Rebate (65-69) | Rebate (70+) |
| Base tier | $101,000 or less | $202,000 or less | 24.288% | 28.337% | 32.385% |
| Tier 1 | $101,001 – $118,000 | $202,001 – $236,000 | 16.192% | 20.240% | 24.288% |
| Tier 2 | $118,001 – $158,000 | $236,001 – $316,000 | 8.095% | 12.143% | 16.192% |
| Tier 3 | Over $158,000 | Over $316,000 | No rebate | No rebate | No rebate |
These thresholds rose from the 2024-25 year, so it is worth rechecking which tier you fall into even if nothing else about your income changed.
Pro tip: if you chose the premium reduction method but earned less than expected, you may get an additional refund at tax time.
4. Zone Tax Offset: Remote Area Recognition
Maximum benefit: $57 (Zone B) to $1,173 (Special Areas). Who qualifies: residents of designated remote areas for 183 or more days. Note: FIFO workers are generally no longer eligible unless their usual place of residence is also zoned.
Zone amounts, unchanged for 2025-26: Zone A is $338 base amount, Zone B is $57 base amount, and Special Areas is $1,173 base amount, plus possible dependent amounts.
Your usual place of residence, not just your work location, needs to be in the designated zone for at least 183 days. Check the ATO’s Australian zone list to confirm your postcode.
5. Invalid and Invalid Carer Offset: Support for Caregivers
Benefit amount: variable, use the ATO calculator to work out your entitlement. Who qualifies: those supporting an invalid spouse, parent, or a child, brother, or sister aged 16 or over who is receiving an eligible government payment, including the Disability Support Pension, Carer Payment, Carer Allowance, and Invalidity Service Pension. Income limit: your adjusted taxable income must be under the current threshold.
What Changed From 1 July 2026
Two changes that were “coming” in last year’s version of this article are now in effect or on the way.
The bottom tax rate dropped to 15%. From 1 July 2026, the 16% rate on income between $18,201 and $45,000 fell to 15%, worth up to $268 a year for anyone earning above $45,000. A further cut to 14% is legislated for 1 July 2027.
The $1,000 instant work deduction is legislated, but not yet claimable. This standard deduction for work-related expenses applies from the 2026-27 income year, which means it will first appear on returns lodged from July 2027. It does not apply to the 2025-26 return you are lodging now, and you can still claim your actual work expenses with receipts this year if that gives a larger deduction. Our work from home deductions guide covers what you can claim under the existing rules.
Before You Lodge: A Quick Checklist
- Confirm which private health insurance tier applies to your 2025-26 income, not last year’s.
- Check whether you qualify as a small business entity for the $1,000 offset.
- Confirm your zone classification if you live in a remote area.
- Review SAPTO eligibility if you or your partner receive a government pension.
- Check the invalid/carer offset if you support a family member with a disability.
- If you are a renter with an investment property, our rental property deductions guide and ATO compliance and audit triggers guide cover the areas the ATO is checking most closely this year.
- Recently married or in a new relationship? See how it affects your return in our marriage and tax guide.

Why Professional Help Matters

At ITP, our tax professionals work through this with clients across every income level, from sole traders to retirees to families with more complex situations.
Don’t leave money on the table. Book a consultation with ITP to check every offset you are entitled to, or explore our small business tax services if you run a business.
Frequently Asked Questions
What’s the difference between tax offsets and deductions?
Deductions reduce your taxable income. Offsets reduce your tax bill directly, dollar for dollar, which generally makes them more valuable.
Can I claim multiple offsets?
Yes. You can claim every offset you are eligible for, and they combine to reduce your total tax liability.
Are offsets refundable?
Most are non-refundable, meaning they can only reduce your tax to zero. The private health insurance offset is the exception. It is refundable.
How do I know if I live in a remote zone?
Check the ATO’s zone list tool using your postcode.
Is there a low income tax offset for 2025-26?
No. The low and middle income tax offset (LMITO) ended after the 2021-22 income year and has not applied since.
When can I claim the $1,000 instant work deduction?
Not this year. It applies from the 2026-27 income year, so it will first appear on returns lodged from July 2027. For your current 2025-26 return, you still need to claim actual work expenses with records.
Get Every Offset You Are Entitled To
Tax offsets reward attention to detail. The rules on eligibility, income thresholds, and timing shift a little every year, and this year is no exception with the new 15% tax rate and the incoming $1,000 instant deduction. ITP Accounting Professionals has helped Australians work through offsets like these for decades. If you want a second set of eyes on your 2025-26 return, get in touch with your local ITP office before you lodge.
