Offsets and deductions both reduce how much tax you pay, but they work at different points in the calculation — mixing them up is one of the more common sources of confusion at tax time.
Deductions vs Offsets
A deduction reduces your taxable income — the number your tax is calculated on. Its value depends on your marginal tax rate: a $100 deduction saves someone on the 30% bracket $30, but someone on the 37% bracket $37. An offset instead reduces the tax payable directly, dollar for dollar, regardless of your tax bracket, up to whatever the offset's cap is.
Low Income Tax Offset (LITO)
The most widely applicable offset. In 2026–27, it's worth up to $700 for anyone with a taxable income of $37,500 or less, phasing out in two stages until it reaches zero at about $66,667. It's applied automatically — see exactly how much it saves you with our Income Tax Calculator Australia.
Seniors and Pensioners Tax Offset (SAPTO)
Available to eligible senior Australians and pensioners who meet age and income tests, SAPTO can significantly reduce or eliminate tax payable for people in that group, on top of the tax-free threshold and LITO. Eligibility depends on your age, whether you receive an Australian Government pension or allowance, and your (and your spouse's, if applicable) income — check current eligibility directly with the ATO, since the tests are more involved than LITO's.
Private Health Insurance Rebate
Depending on your income and age, the government subsidises part of your private health insurance premium, either as a reduced premium upfront or as a tax offset claimed through your return if you paid the full premium during the year. The rebate percentage is income-tested and reduces (or disappears entirely) above certain thresholds.
Invalid and Invalid Carer Tax Offset
Available if you maintain an invalid or carer who is your spouse, child or sibling and who receives a disability support pension, carer payment, or similar. It's a smaller, more specific offset than LITO, with its own eligibility and income tests.
Zone Tax Offset
For people who live or work in remote areas of Australia for more than half the year, recognising the higher cost of living and isolation in those zones. The offset amount depends on which zone (ordinary or special) you're in, with the special zone — covering the most remote areas — offering a larger amount than the ordinary zone.
Superannuation-Related Offsets
A couple of offsets sit at the intersection of tax and super. The spouse super contributions tax offset rewards someone who contributes to a low-income or non-working spouse's super fund, worth up to $540 a year depending on the spouse's income and the contribution amount. There's also a small offset available for some early-stage investors and venture capital arrangements, though these are far less commonly relevant to typical employees than LITO, SAPTO or the private health insurance rebate.
Beneficiary Tax Offset
Available to people who received certain government payments during the year, such as JobSeeker Payment, Youth Allowance or Parenting Payment, which count as taxable income. The offset helps ensure that receiving a taxable government payment doesn't itself push someone into an unexpectedly large tax bill for a year with otherwise low income.
Can You Claim More Than One Offset?
Yes — offsets aren't mutually exclusive, and many people are entitled to more than one at once. A low-income senior, for example, could potentially qualify for both LITO and SAPTO in the same year. There's no need to choose between them: the ATO applies every offset you're eligible for when your return is assessed, though the combined total still can't reduce your tax payable below zero.
Worked Example: LITO in Practice
On a $35,000 taxable income, tax before any offset is a modest amount under the 15% bracket. LITO reduces that further, since $35,000 sits below the offset's first taper point — meaning the full offset applies and noticeably lowers the effective tax rate on a lower income, which is exactly the policy intent. Try your own numbers with our Income Tax Calculator Australia to see LITO applied automatically alongside your bracket-by-bracket breakdown.
What Offsets Don't Do
Offsets don't reduce the Medicare levy — that's calculated separately from your income tax and offset entitlements. They also can't create a refund larger than the tax you'd otherwise owe; if your tax payable is already zero, an offset simply has nothing left to reduce. And unlike a deduction, an offset has no effect on your taxable income itself — it only changes the final tax bill calculated from it, which matters if your taxable income is used elsewhere, such as for HELP repayment or Medicare levy surcharge calculations.
Our Income Tax Calculator Australia automatically applies LITO to your result, alongside a full bracket-by-bracket breakdown of your tax.
