Tax Offsets vs Deductions: What Actually Saves You More in 2025-26?
At tax time, everyone wants to pay less. But many Australians mix up two very different ways to reduce their bill: tax offsets and tax deductions. They sound similar, but they work in completely different ways – and one is usually worth more to you in dollar terms. This guide explains the difference, shows you the 2025-26 rates, and helps you work out which one gives you the biggest bang for your buck.
What’s the difference?
A tax deduction reduces your taxable income. For example, if you earn $90,000 and claim $1,000 in deductions, you only pay tax on $89,000. The tax saving depends on your marginal tax rate – the more you earn, the more each deduction is worth.
A tax offset (also called a tax credit) directly reduces the tax you owe, dollar for dollar. If you owe $15,000 in tax and have a $1,000 offset, your bill drops to $14,000. Offsets are generally the same value for everyone, regardless of income (though some have income limits).
Simple example:
- Deduction of $1,000 at the 32.5% marginal rate (2025-26): saves you $325
- Offset of $1,000: saves you $1,000
So offsets are usually more generous – but they’re also rarer and often have eligibility criteria.
2025-26 tax offsets you need to know
Here are the main offsets available for the 2025-26 financial year (income year 1 July 2025 to 30 June 2026):
Low Income Tax Offset (LITO)
- For taxable income up to $66,667
- Maximum offset: $700
- Phases out from $37,500 to $66,667
- Automatically applied when you lodge your tax return
Low and Middle Income Tax Offset (LMITO) – not available
The LMITO ended on 30 June 2022. Don’t expect it in your 2025-26 return.
Senior Australians and Pensioners Tax Offset (SAPTO)
- For eligible seniors and pensioners
- Maximum offset: $2,230 (singles), $1,602 (couples combined)
- Income thresholds apply
Private Health Insurance Offset
- For holding eligible private hospital cover
- Claimed as a reduction on your premium or as a tax offset
- Income-based tiers: 8.2% to 24.6% of premiums
Other offsets
- Zone offset for living in remote areas
- Invalidity offset for disability support pensions
- Franking credit offset from dividends
How deductions work in 2025-26
Deductions are claimed for work-related expenses, donations, and other costs. The most common for everyday Australians:
- Work-related expenses (uniforms, tools, home office)
- Self-education (if it relates to your current job)
- Charitable donations over $2
- Income protection insurance premiums
- Interest on investments
Your deduction’s value equals your marginal tax rate. For 2025-26, the ATO rates are:
| Taxable income | Tax on this income | Marginal rate |
|---|---|---|
| $0 – $18,200 | Nil | 0% |
| $18,201 – $45,000 | 19c per $1 over $18,200 | 19% |
| $45,001 – $135,000 | $5,092 + 32.5c per $1 over $45,000 | 32.5% |
| $135,001 – $190,000 | $34,342 + 37c per $1 over $135,000 | 37% |
| $190,001+ | $54,692 + 45c per $1 over $190,000 | 45% |
Plus the Medicare levy of 2% (and possibly the Medicare levy surcharge if you don’t have hospital cover and earn over $93,000 for singles).
So if you’re in the 32.5% bracket, a $500 deduction saves you $162.50. A $500 offset would save you $500.
Which should you chase?
Chase offsets first – they’re worth more. But you can’t usually choose; you either qualify or you don’t. The practical approach:
- Claim every deduction you’re entitled to – they add up, especially if you’re in a higher bracket.
- Check if you qualify for any offsets – LITO and SAPTO are automatic, but private health insurance and zone offsets need action.
- Don’t overclaim – the ATO is cracking down on exaggerated work-related claims. Keep receipts and records.
A common mistake is thinking a deduction is a dollar-for-dollar saving. It’s not. If you’re in the 19% bracket, a $1,000 deduction saves you just $190.
How to calculate your actual tax
Instead of guessing, use our income tax calculator. It handles:
- 2025-26 tax brackets
- Medicare levy and surcharge
- LITO and SAPTO automatically
- Your deductions and offsets
Just enter your taxable income, any deductions, and your offset amounts. You’ll see your estimated tax payable and refund instantly.
Real-world example: Sarah, $85,000 salary
Sarah earns $85,000 in 2025-26. She claims $2,000 in work deductions and qualifies for the LITO.
- Taxable income after deductions: $83,000
- Tax before offsets: $5,092 + 32.5% × ($83,000 – $45,000) = $5,092 + $12,350 = $17,442
- Plus Medicare levy: 2% × $83,000 = $1,660
- Total tax + levy: $19,102
- Less LITO: $700 (phased out from $37,500, so reduced)
- Estimated tax payable: ~$18,402
If Sarah had no deductions, her tax would be higher. But her $2,000 deduction only saved her $650 (32.5% of $2,000). A $700 offset saved her the full $700.

- Use the ATO’s myDeductions app to record expenses.
- If you’re unsure about an offset, check the ATO website or ask a registered tax agent.
