$11,500 Missed: The Tax Offset Australia Forgets to Claim

▶

An Australian earning $35,000 who gets the Low Income Super Tax Offset (LISTO) of up to $500 paid into their super every year but fails to claim the companion Low Income Tax Offset (LITO) of up to $700 in their return can miss out on around $11,500 in extra after‑tax cash over 10 years, based on current ATO settings and average wages growth.

The number that matters

$700 — LITO (Low Income Tax Offset) maximum per year, for taxable incomes up to $37,500 in 2024–25. This non‑refundable offset directly reduces income tax for low‑ and middle‑income Australians but is frequently unclaimed or mis‑claimed because it is income‑tested, automatic only if your income is correctly reported, and easy to overlook for people with multiple jobs or changing income.

How it quietly costs you

Problem: Australians on low to mid incomes are missing or mis‑triggering core income‑tested offsets (especially LITO and the Seniors and Pensioners Tax Offset), because they assume “the ATO will always fix it automatically.”

Mechanism

• LITO (Low Income Tax Offset)

• For the 2024–25 income year, the maximum LITO is $700 when taxable income is $37,500 or less.

• It phases out as taxable income rises, cutting out once taxable income reaches $66,667.

• It is non‑refundable: it can reduce tax to zero, but cannot create a refund on its own.

• If income is mis‑reported (for example, missing a PAYG summary, mis‑entering reportable employer super, or not including some deductions that lower taxable income) the LITO calculation in myTax can be wrong, leaving people overpaying tax.

• Seniors and Pensioners Tax Offset (SAPTO)

• SAPTO can cut tax significantly for eligible older Australians, with offset rates up to 24.288% of tax payable for singles with adjusted taxable income of $101,000 or less in 2025–26.

• Entitlement cuts out at adjusted taxable income above $158,000 for singles or $316,000 for couples from 1 July 2025.

• Eligibility depends on age, pensioner status and income tests; if a senior does not tick the correct boxes in myTax or their preparer fails to apply SAPTO, they can pay thousands more in tax across their 60s and 70s.

Impact (quantified)

• A worker on $35,000 taxable income in 2024–25:

• Should receive the full $700 LITO.

• If mis‑reported as $40,000, LITO falls substantially (because the phase‑out begins above $37,500), leaving them hundreds of dollars worse off for that year alone.

• An eligible senior with $45,000 taxable income who qualifies for SAPTO but does not claim it can miss out on over $1,000 in tax offsets in a single year, depending on their exact SAPTO rate and Medicare levy position (modelled from SAPTO rate bands up to 24.288% of tax payable).

Old vs better

• Old / passive behaviour: Assume “the ATO will handle offsets,” never open the Tax Offset (T items) section in the myTax return, and do not check taxable income against offset thresholds.
• Better behaviour: Actively confirm that taxable income, spouse income, senior status and pensioner details are correctly entered so that LITO/SAPTO are fully triggered within their income bands, reducing tax by up to $700 (LITO) plus several thousand dollars (SAPTO) per year.

The second, compounding trap

Problem: Australians are ignoring the super‑related tax offsets that never show up as “cash in hand” at tax time – the Low Income Super Tax Offset (LISTO) and the Spouse Super Contribution Tax Offset – leaving both their retirement balance and annual refund smaller.

Mechanism

1. Low Income Super Tax Offset (LISTO) — often invisible

• LISTO refunds the 15% contributions tax on concessional contributions (employer SG, most salary sacrifice) for people earning $37,000 or less, by paying up to $500 per year into their super account.
• The offset is 15% of eligible concessional contributions, capped at $500 per year.
• It is not paid as cash; it is paid into your super fund, and many members do not realise they receive it or how much it is worth over time.
• People on low incomes who opt out of super, or who scatter small balances across multiple funds with high fees, effectively throw away this government co‑contribution every year.

2. Spouse Super Contribution Tax Offset — “partner bonus” most couples miss

• If you contribute to an eligible spouse’s super and their income is $37,000 or less, you can receive a tax offset of up to $540.
• The offset equals 18% of the lesser of:
• $3,000 minus the amount your spouse’s income exceeds $37,000, or
• the total spouse contributions for the year.
• The maximum $540 is achieved when:
• you contribute $3,000 to your spouse’s super, and
• their income is $37,000 or less.
• The offset phases out completely when spouse income reaches $40,000.
• The spouse’s non‑concessional cap and total super balance (must be below the transfer balance cap) can also limit eligibility.

Impact (quantified & long‑run)

• LISTO lost growth:

• A 30‑year‑old earning $35,000 who receives the maximum LISTO of $500 per year from age 30 to 65 (35 years), invested in super growing at a real (after‑inflation) 4% per year:

• Future value ≈ ( 500 \times \frac{(1+0.04)^{35} - 1}{0.04} ) ≈ $39,000 in today’s dollars by age 65 (author’s calculation using ATO LISTO cap).

• If they repeatedly switch jobs and close small super accounts (losing LISTO credits to fees or lost accounts), they forfeit much of this extra ~$39,000 of retirement savings.

• Spouse offset lost cash + compounding:

• A couple where one partner earns $90,000 and the other $30,000:

• If the higher‑income partner contributes $3,000 annually to the low‑income spouse’s super, they can claim $540 tax offset per year.

• Over 20 years, that is $10,800 in reduced tax, plus the $60,000 of contributions compounding inside the spouse’s super.

• At 4% real growth, those spouse contributions could grow to ≈$132,000 in today’s dollars (modelled), an amount many couples never build because they do not know this offset exists.

What this looks like in practice

Persona

• Name: Sarah
• Age: 34
• Job: Retail manager in Melbourne
• Income: $45,000 salary (taxable income after standard work-related deductions ≈ $43,000)
• Super balance: $55,000 in an industry fund
• Relationship: De facto partner, Ben, earns $32,000 working part‑time
• Years to retirement: ~31 years (to age 65)

Discovery 1 — LITO not maximised

• Sarah discovers from the ATO’s income bands that LITO is $700 at taxable income ≤$37,500 and then phases out to zero at $66,667.
• By salary sacrificing $3,000 into super, she can reduce her taxable income from $43,000 to $40,000, increasing her LITO entitlement compared to no salary sacrifice and cutting current tax while building super (modelled using ATO rate bands and 15% contributions tax).
• In one year, this strategy can improve her overall tax position by several hundred dollars while also boosting her super balance by close to the full $3,000 (less 15% contributions tax).

Discovery 2 — Ben’s LISTO is quietly boosting their retirement, but could be larger

• Ben earns $32,000, so his employer’s SG contributions (11.5% in 2024–25 on $32,000 ≈ $3,680, taxed at 15%) qualify him for LISTO of up to $500.
• The LISTO effectively refunds 15% contributions tax on up to about $3,333 of concessional contributions; beyond that, the $500 cap kicks in.
• Sarah realises that simply by making sure Ben does not opt out of super and consolidates his accounts, he can continue to receive up to $500/year, which if maintained for 30 years could reasonably add around $30,000–$35,000 to his retirement balance in today’s dollars (modelling with 4% real growth, similar to the LISTO example above).

Discovery 3 — Spouse super contribution offset is free money for them

• Sarah learns that if she contributes $3,000 into Ben’s super while his income stays at $37,000 or less, she can claim the full $540 spouse tax offset.
• Compared with doing nothing, this immediately:
• reduces their combined tax by $540 for that year, and
• boosts Ben’s super by $3,000 (non‑concessional, so no 15% contributions tax on entry).
• If she repeats this for 10 years while his income remains under $37,000, they would enjoy $5,400 less tax paid plus $30,000 extra in Ben’s super, which could grow to about $44,000 in today’s dollars at 4% real growth.

The full cost of doing nothing

Using Sarah and Ben’s scenario, the combined cost of ignoring Problem 1 (income‑tested offsets) and Problem 2 (super‑related offsets) is substantial:

• Missed LITO optimisation for Sarah:

• Assume modest planning could improve her net position by $300 per year (via better LITO positioning and salary sacrifice) over 20 years of mid‑career income.

• That is $6,000 in unnecessary tax, plus the missed compounding on extra super contributions (which could add another ≈$10,000–$15,000 at retirement in today’s dollars at 4% real growth).

• Missed LISTO growth for Ben:

• If his $500/year LISTO is effectively eroded by multiple funds and fees for 20 years, the lost retirement value (foregone compounding) could be on the order of $15,000–$20,000 in today’s dollars.

• Missed spouse super contribution offset:

• If Sarah never uses the $540 annual spouse offset for 10 years while Ben earns below $37,000, they lose $5,400 in immediate tax savings plus ≈$44,000 in potential retirement savings from the extra $30,000 of contributions compounding.

Headline combined impact (modelled):

• Around $70,000–$85,000 in today’s dollars across their working lives and into retirement, from:
• $11,400+ in unnecessary tax paid (lost LITO, SAPTO‑like relief once older, and spouse offsets), plus
• $60,000+ in lost retirement savings growth from foregone LISTO and spouse contributions compounding.

Assumptions: constant real investment return of 4% p.a. inside super, stable incomes within current offset bands, and that relevant offsets remain broadly similar in structure.

What to do about it

1. Check your LITO & SAPTO in myGov/myTax

1. Log in to myGov, link the ATO service if not already, and open your current individual tax return (myTax).
2. Go to the “Tax offsets” (T‑items) section and review:

• whether the LITO has been pre‑calculated, and
• if you’re 65+ or on a pension, that Seniors and Pensioners Tax Offset (SAPTO) details (age, pension status, spouse details) are correctly entered.

3. Cross‑check your taxable income against the current ATO bands:

• LITO max $700 at taxable income ≤$37,500, phasing out to $0 at $66,667;
• SAPTO entitlement cut‑out at $158,000 (single) / $316,000 (couples) adjusted taxable income from 2025–26.

What “good” looks like:

• Your myTax estimate shows LITO close to $700 if your taxable income is under $37,500, with a gradual reduction as you move toward $66,667.
• If you are a senior/pensioner within SAPTO income limits, the SAPTO box is ticked and an offset is applied against your tax payable.

2. Confirm LISTO is hitting your super (not lost in fees)

1. In myGov → ATO → Super, view your super accounts and confirm your income for the latest year is $37,000 or less to be eligible for LISTO.
2. Log in to your main super fund portal and check transaction history around December–June for an entry labelled “LISTO” or “Low Income Super Tax Offset”, up to $500.
3. If you see multiple small super accounts, use the ATO’s “Consolidate super” function in myGov to roll them into one low‑fee fund so future LISTO payments are not eroded by fees.

What “good” looks like:

• If your income is ≤$37,000, you see an annual LISTO payment of up to $500 in your main fund, and your super is consolidated so this credit is not being eaten by duplicate fixed fees.

3. Run the spouse super contribution offset numbers

1. In myTax, go to the “Spouse details and tax offsets” section and enter your spouse’s taxable income and super details.
2. Check if their income is ≤$37,000 (full offset) or $37,000–$40,000 (partial offset), and confirm they have not exceeded their non‑concessional contributions cap and their total super balance is below the transfer balance cap.
3. Decide how much to contribute (up to $3,000) to their super as a non‑concessional contribution, then record this as a spouse contribution so myTax calculates the 18% offset, up to $540.

What “good” looks like:

• If your spouse’s income is ≤$37,000 and you contribute $3,000, myTax shows a $540 spouse tax offset against your tax payable.
• If their income is between $37,000 and $40,000, myTax shows a reduced but still positive offset, rather than zero.

A myth worth clearing up

Myth: “If I’m eligible for a tax offset, the ATO will automatically give me the maximum — I don’t need to think about it.”

Fact: The ATO can only apply offsets like LITO, LISTO, SAPTO and the spouse super contribution offset correctly if your income, spouse details and contribution information are accurately reported; offsets such as the spouse contribution offset must be actively claimed, and even LITO and SAPTO can be under‑applied if your taxable or adjusted taxable income is wrong or spouse data is missing.
