How tax offsets differ from deductions

The terms get mixed up constantly, but offsets and deductions work at completely different stages of your tax calculation — and understanding where each one hits matters for getting the most out of both.

A tax deduction reduces your taxable income before tax rates are applied. If you claim a $1,000 deduction and you're in the 30% bracket, you save $300. The saving depends on your marginal rate.

A tax offset (also called a rebate) reduces the actual tax you owe after it has been calculated. A $700 offset cuts your tax bill by $700, regardless of which bracket you're in.

How you claim itManually, with records/receiptsMost are automatic (ATO calculates)
Important: Most tax offsets are non-refundable — they can reduce your tax to zero but won't generate a cash refund. If your tax liability is already $0 (because your income is below the tax-free threshold), offsets like LITO and SAPTO have nothing to reduce.

Low Income Tax Offset (LITO)

LITO is the most widely used tax offset in Australia. It applies automatically to every resident taxpayer earning up to $66,667 — you don't need to claim it or tick any box. The ATO calculates it when you lodge your return.

2025-26 LITO rates and thresholds

The thresholds and rates have remained the same since 2020-21:

Taxable incomeLITO amount
$0 – $37,500$700 (full offset)
$37,501 – $45,000$700 minus 5 cents for every $1 over $37,500
$45,001 – $66,667$325 minus 1.5 cents for every $1 over $45,000
$66,668+$0 (no offset)

How the phase-out works

LITO phases out in two stages. Between $37,501 and $45,000, you lose 5 cents of offset for every additional dollar of income — that's a fast reduction that strips $375 of offset across just $7,500 of income. By the time you reach $45,000, your LITO has dropped from $700 to $325.

The second stage is gentler. Between $45,001 and $66,667, you lose 1.5 cents per dollar — so the remaining $325 tapers away over $21,667 of income.

What this means in dollars

On a $40,000 salary (2025-26)

$575 LITO offset

$700 − ($40,000 − $37,500) × 0.05 = $575. This is applied after your base income tax of $3,688 is calculated, reducing your income tax to $3,113.

Why LITO causes tax refunds

Your employer's PAYG withholding doesn't account for LITO. Your payslip tax is calculated without it, meaning more tax is withheld throughout the year than you actually owe. When you lodge your return and the ATO applies LITO, the overpayment comes back as a refund. This is why many people earning under $66,667 get a refund even without any deductions.

The “real” tax-free threshold

The official tax-free threshold is $18,200, but LITO effectively extends it. A resident earning $21,884 owes $589 in base income tax ($18,200 at 0% + $3,684 at 16%), but the full $700 LITO more than wipes that out. In practice, a resident with no other income pays zero income tax up to about $21,884 — and if SAPTO also applies, the effective tax-free threshold rises to $33,532.

Try this scenario

Enter a $35,000 salary to see the full $700 LITO applied — then change it to $55,000 to watch the offset phase out.

Seniors and Pensioners Tax Offset (SAPTO)

SAPTO is a tax offset for older Australians that can significantly increase the amount of income you can earn before paying tax. Combined with the tax-free threshold and LITO, an eligible single person can earn up to $33,532 completely tax-free.

Who is eligible

You qualify for SAPTO if, on 30 June of the financial year, you meet both of these conditions:

  1. You have reached Age Pension age — that's 67 years old (since 1 July 2023). For the 2025-26 financial year, you must turn 67 by 30 June 2026.
  2. You meet one of these pension-related conditions:
    • You received an Australian Government pension or allowance (Age Pension, Disability Support Pension, Carer Payment, etc.) at any time during the year
    • You would qualify for such a pension except that your income or assets are too high (this is the “self-funded retiree” pathway — you don't actually need to receive a pension)
    • You received a qualifying pension from the Department of Veterans' Affairs

The second condition is deliberately broad — most Australians aged 67+ qualify, including self-funded retirees who have never applied for a pension.

2025-26 SAPTO amounts and thresholds

StatusMax offsetTax-free up toOffset cuts out at
Single$2,230$33,532$50,119
Couple (each)$1,602$28,974$41,790
Illness-separated (each)$2,040$32,279$48,599

“Tax-free up to” figures include the tax-free threshold, LITO, and SAPTO combined. “Offset cuts out at” is the rebate income where SAPTO reduces to $0.

The shade-out mechanism

SAPTO reduces by 12.5 cents for every $1 of rebate income above the shade-out threshold. For a single person, the full $2,230 offset applies below $33,532 in rebate income. Above that, the offset decreases until it reaches zero at $51,372.

The formula for a single person is:

SAPTO = $2,230 − (rebate income − $33,532) × 0.125

What counts as “rebate income”

SAPTO uses rebate income, which is broader than taxable income. It's calculated as:

  • Your taxable income
  • Plus reportable superannuation contributions (salary sacrifice, personal deductible contributions)
  • Plus total net investment losses (negative gearing losses are added back)
  • Plus adjusted fringe benefits totals

This means you can't reduce your rebate income by salary sacrificing into super or claiming investment losses to get a bigger SAPTO.

Spouse transfer

If both you and your spouse are SAPTO-eligible and one of you has unused offset (because their tax is already zero), the unused portion can transfer to the other partner. The ATO works this out automatically when both people lodge. This can be particularly valuable when one partner has significantly higher income than the other.

What this means in dollars

Single retiree earning $40,000 (2025-26)

$1,422 SAPTO offset

$2,230 − ($40,000 − $33,532) × 0.125 = $1,422. Combined with LITO ($325 at this income), total offsets of $1,747 reduce your tax from $3,488 to $1,741.

Try this scenario

Enter a $40,000 income with SAPTO enabled to see how the offset stacks with LITO and the tax-free threshold.

Try this scenario

Other common tax offsets

Beyond LITO and SAPTO, there are several other offsets that may apply depending on your circumstances. Unlike LITO and SAPTO (which are automatic), some of these need to be claimed on your tax return.

Spouse super contribution offset

If you make after-tax super contributions to your spouse's super fund, you may be able to claim a tax offset of up to $540. To get the full $540, you need to contribute at least $3,000 and your spouse's income must be below $37,000. The offset phases out between $37,000 and $40,000 of spouse income, reaching zero at $40,000.

“Income” for this test includes assessable income, reportable fringe benefits, and reportable employer super contributions. Your spouse doesn't need to be working — this offset is often used when one partner is on parental leave, studying, or retired below Age Pension age.

Zone tax offset

If you live in a designated remote or isolated area of Australia for at least 183 days during the year, you may be eligible for the zone tax offset. The amount depends on which zone your usual place of residence falls in:

ZoneFixed amountExamples
Zone A$338Most of NT, remote WA/QLD/SA
Zone B$57Regional NSW/QLD/WA/SA
Special area (within Zone A)$1,173Very remote locations 250km+ from towns of 2,500

The offset is based on your usual place of residence, not where you work. FIFO workers who live in a capital city but fly to a remote mine site generally don't qualify. The ATO maintains a searchable zone list where you can check your postcode.

Low Income Super Tax Offset (LISTO)

LISTO is a government contribution paid directly into your super fund if your adjusted taxable income is $37,000 or less. It effectively refunds the 15% tax charged on your employer's super contributions, up to a maximum of $500 per year.

You don't need to apply — the ATO calculates LISTO when you lodge your return and pays it into your super fund automatically. Note that LISTO goes into your super account, not your bank account, and you must earn at least 10% of your income from employment or carrying on a business.

Private health insurance rebate

If you hold a complying private health insurance policy, the government pays a percentage of your premium. The rebate percentage depends on your age and income — it ranges from 8.202% to 32.812% for 2025-26. You can receive the rebate in two ways:

  • As a premium reduction — your insurer applies it and you pay less each month
  • As a refundable tax offset — claim the full amount when you lodge your return

This is one of the few refundable offsets — any excess beyond your tax liability is paid to you as a cash refund.

Invalid and invalid carer tax offset

If you maintain an invalid person aged 16 or over, or their carer, you may claim this offset. Your combined adjusted taxable income (you and your spouse) must be $117,194 or less. This is a less commonly claimed offset that applies in specific care situations.

Refundable vs non-refundable offsets

This distinction catches people out. Most offsets are non-refundable, which means they can only reduce your tax to zero — any leftover offset is lost.

Non-refundable offsetsRefundable offsets
LITO, SAPTO, zone offset, spouse super offset, invalid carer offsetPrivate health insurance rebate, franking credits, LISTO (paid into super)
Can reduce tax to $0 onlyExcess paid as a cash refund
Unused amount is forfeitedNothing is wasted
Franking credits note: If you receive dividends from Australian companies with franking credits attached, those credits are a refundable tax offset. If your total franking credits exceed your tax payable, you receive the excess as a cash refund — even if your taxable income is below the tax-free threshold. This is why some retirees with share portfolios receive tax refunds despite paying no tax.

Worked examples

Example 1: Full-time worker on $42,000

Sam is 30, a resident, with no HECS debt and private health insurance.

Step 1 — Base tax: ($42,000 − $18,200) × 16% for the first $26,800, then ($42,000 − $45,000) = $0 in the 30% bracket. Wait — $42,000 is below $45,000, so all $23,800 above $18,200 is taxed at 16%.

Income tax = $23,800 × 0.16 = $3,808

Step 2 — LITO: $42,000 is between $37,501 and $45,000, so LITO = $700 − ($42,000 − $37,500) × 0.05 = $700 − $225 = $475

Step 3 — Medicare Levy: $42,000 × 0.02 = $840

Total tax: $3,808 − $475 + $840 = $4,173

Effective rate: $4,173 ÷ $42,000 = 9.9%

Without LITO, Sam's tax would be $4,648 — so the offset saves $475.

Example 2: Retired couple, one earning $38,000

Margaret is 71 and earns $38,000 from a mix of super pension and part-time work. She qualifies for SAPTO as a single (her husband passed away).

Step 1 — Base tax: ($38,000 − $18,200) × 0.16 = $19,800 × 0.16 = $3,168

Step 2 — LITO: $38,000 is just into the phase-out: $700 − ($38,000 − $37,500) × 0.05 = $700 − $25 = $675

Step 3 — SAPTO: Rebate income of $38,000 is above $33,532, so: $2,230 − ($38,000 − $33,532) × 0.125 = $2,230 − $558 = $1,672

Step 4 — Medicare Levy: $38,000 × 0.02 = $760

Total: $3,168 − $675 − $1,672 + $760 = $1,581

Without SAPTO, Margaret's tax would be $3,253 — so SAPTO saves her $1,672. If her income were $33,532 or less, she'd pay zero income tax.

Try this scenario

Enter $38,000 with SAPTO enabled to see Margaret's combined LITO + SAPTO offsets.

Example 3: Very low income — the “wasted” offset trap

Jake earns $20,000 as a part-time worker. His base income tax is ($20,000 − $18,200) × 0.16 = $288. LITO would give him $700, but because it's non-refundable, it can only reduce his tax to zero — the remaining $412 of offset is lost. His Medicare Levy of $400 is still payable, so Jake's total tax is just the $400 Medicare Levy.

Common traps and mistakes

  1. Confusing offsets with deductions on your tax return
    You can't “claim” LITO or SAPTO the way you claim a work expense. These are calculated automatically by the ATO. There is no label on the tax return for them.
  2. Thinking SAPTO uses taxable income
    SAPTO is assessed on rebate income, not taxable income. If you have negatively geared investments or salary sacrifice into super, those amounts get added back when calculating your rebate income. This catches retirees who think their investment losses will help them access a larger SAPTO.
  3. Assuming LITO is included in PAYG withholding
    It isn't. Your employer withholds tax as though LITO doesn't exist. Don't adjust your withholding to “compensate” unless you've lodged a PAYG withholding variation with the ATO.
  4. Missing SAPTO because you didn't tick the box
    While LITO is fully automatic, SAPTO requires you to indicate your eligibility on your tax return (item T1). If you're eligible and don't claim it, you miss out.
  5. Non-residents expecting LITO
    LITO and SAPTO are only available to Australian residents for tax purposes. If you're a non-resident or on a working holiday visa, neither offset applies — and you also don't get the $18,200 tax-free threshold.
  6. Forgetting the LMITO is gone
    The Low and Middle Income Tax Offset (LMITO) — the temporary “lamington” offset of up to $1,500 — ended after the 2021-22 financial year. It no longer applies. Only LITO remains for low-income earners from 2022-23 onwards.
