How do I maximise my tax refund in Australia? It’s a question worth asking carefully, because many Australians leave genuine money on the table every tax year, not through fraud or complicated schemes, but simply through not knowing what the ATO actually allows. At Tax NextGen, we speak with hundreds of Australians each financial year who are genuinely surprised at what they’ve been missing: straightforward work deductions they’ve never claimed, offsets the ATO applies automatically, and timing moves that most people never consider.

This article gives you a direct answer for the 2025, 26 financial year (ending 30 June 2026). We’ll cover deductions, offsets, the timing strategies that require action before 1 July 2026, the records you actually need to keep, and the mistakes that quietly shrink refunds before a return is even lodged.

How to maximise your tax refund in Australia: work-related deductions

The biggest misconception is that deductions are only worth pursuing if your situation is complicated. The ATO’s core rule is straightforward: the expense must be work-related, not reimbursed by your employer, and you must keep a record to support it. Many Australians, full-time, part-time, and casual employees, have more legitimately claimable expenses than they realise, particularly once they look beyond the obvious categories.

One critical point for this year: the $1,000 standard deduction does not apply to 2025, 26. That measure starts from 2026, 27. For the current financial year, there is no standard $1,000 deduction, so every dollar you claim must be substantiated with the records required under ATO rules.

The working from home fixed rate: 70 cents per hour

The ATO’s fixed rate method allows you to claim 70 cents for every hour you work from home in 2025, 26. That rate covers electricity and gas, internet, mobile and home phone usage, and stationery and computer consumables like printer ink and paper. What it does not cover is the decline in value of office furniture or technology, so a work laptop, ergonomic chair, or standing desk used for work may still be claimable separately under depreciation rules.

The key condition is that you must record your actual hours worked from home across the full year. A diary, calendar entries, or a spreadsheet all satisfy the requirement. Estimates are not acceptable to the ATO under this method. That point is explicit in their guidance.

Uniforms, tools, vehicle and self-education expenses

The other major claimable categories include occupation-specific or protective clothing (not ordinary work attire), tools and equipment used for your role, vehicle expenses for work-related travel between sites or to clients, and self-education costs directly connected to your current position. Union fees and professional membership fees remain fully claimable in 2025, 26 and are specifically preserved even as the standard deduction regime changes in future years.

For vehicle claims, you choose between the cents-per-kilometre method (no logbook required, capped at 5,000km) and the logbook method (12-week continuous logbook applied to all car running costs). On substantiation: total work-related claims under $300 don’t require written receipts, but you still need to show how you calculated the amount. Above $300, written evidence is mandatory.

Tax offsets that directly reduce what you owe

A deduction reduces your taxable income. An offset reduces the actual tax you pay, dollar for dollar. Many Australians overlook offsets entirely, either because they’re unaware they exist or because they assume they won’t qualify. Checking your eligibility costs nothing and takes minutes.

The Low Income Tax Offset and who qualifies

The Low Income Tax Offset (LITO) provides up to $700 for Australian residents with taxable income of $37,500 or less. It phases out progressively: by 5 cents per dollar between $37,501 and $45,000, then by 1.5 cents per dollar from $45,001 to $66,667. Above $66,667, the offset disappears entirely. The ATO applies LITO automatically. You don’t need to claim it.

Understanding where you sit relative to those thresholds matters for planning. If a legitimate deduction brings your taxable income below $37,500, the full $700 offset applies. That’s a meaningful difference in your final refund, and it’s one reason that every claimable deduction matters, even if individually it seems small.

Seniors, private health insurance and other specialist offsets

Eligible seniors and pensioners may qualify for the Seniors and Pensioners Tax Offset (SAPTO), worth up to $2,230 for single individuals. It’s means-tested against rebate income and phases out depending on relationship status, so the actual amount varies. The private health insurance rebate can be claimed as a tax offset at return time if you haven’t already taken it as a premium reduction; specific income thresholds and phase-out rates apply for 2025, 26, so check the current ATO guidance for the figures relevant to your situation.

If you’re in a remote or regional area, the Zone Tax Offset is worth checking. If you support an eligible invalid or carer dependant, the Invalid and Carer Tax Offset may also apply. These are more specialised, but they exist precisely for people in those circumstances, and they’re frequently overlooked.

Pre-30 June moves to maximise your tax refund in Australia

Most Australians don’t think about tax strategy until after 30 June. By then, the opportunities for 2025, 26 are gone. Two moves in particular are legal, ATO-sanctioned, and time-sensitive, action is required before 1 July 2026.

Prepaying deductible expenses before 1 July

Under the ATO’s 12-month prepayment rule, if you prepay a deductible expense before 1 July 2026 and the service period is 12 months or less, ending no later than 30 June 2027, you can claim the full deduction in 2025, 26. Common qualifying prepayments include professional subscriptions, professional indemnity or income protection insurance premiums, work-related course fees, and relevant memberships.

This is not a loophole. It’s an established ATO rule designed for this purpose, available to individual taxpayers with deductible non-business expenditure. The payment must be for services or a benefit to be provided, not for capital items, and the timing conditions above must be satisfied.

Personal super contributions and the $30,000 concessional cap

If you make an after-tax personal super contribution before 1 July 2026 and lodge a notice of intent to claim a deduction with your fund, that contribution becomes tax-deductible. Your fund must acknowledge the notice in writing before you lodge your tax return. The ATO requires the notice to be given on or before the earlier of the day you lodge your return for that year or the end of the following financial year, and certain events, such as withdrawals or rollovers, can invalidate the notice. Check the ATO’s super deduction guidance for the precise timing rules relevant to your circumstances.

The concessional cap for 2025, 26 is $30,000, rising to $32,500 from 1 July 2026. The practical effect is a dollar-for-dollar reduction in taxable income. Your super fund pays 15% contributions tax on the deductible amount, but for most taxpayers on the 19% or 32.5% marginal rate, the net benefit is clear. Age-based eligibility rules apply: if you’re between 67 and 74, a work test or work test exemption may apply, and above 75 the deduction is generally not available. Confirm the current ATO rules for your age group before acting.

The records the ATO expects you to keep

Most refund problems don’t come from the claim itself. They come from the absence of evidence to support it. Good record-keeping doesn’t need to be complicated, it needs to be consistent and cover the right things.

Home office, phone and internet evidence

Under the fixed rate WFH method, you need a record of every hour worked from home across the full year, plus at least one document per expense type the rate covers, for example, an electricity bill and a stationery receipt. All records must be kept for five years from the date you lodge your return.

One mistake worth flagging specifically: if you use the WFH fixed rate, your phone and internet costs are already included in that 70 cents per hour. Claiming them separately on top is a common error the ATO actively looks for. If you want to claim phone and internet costs separately under an actual-cost approach, you need bills plus a four-week representative diary showing the work-related percentage, and you cannot also use the fixed rate for those same items.

Vehicle: logbook versus cents per kilometre

The logbook method requires a 12-week continuous logbook recording dates, destinations, purpose of travel, and odometer readings. That logbook establishes a business-use percentage applied to all car running costs throughout the year. It generally produces the highest deduction for people with significant work travel. Update the logbook whenever your work travel patterns change materially. An outdated logbook that no longer reflects actual use won’t hold up under review.

The cents-per-kilometre method is simpler: no logbook is required, but you must be able to demonstrate how you calculated the kilometres claimed, such as through a work calendar or client diary. The method is capped at 5,000km. Regardless of which method you use, keeping fuel, maintenance, and registration receipts provides useful supporting documentation.

Mistakes that quietly shrink your refund

These are errors we see regularly on returns people bring to Tax NextGen after lodging through generic online platforms or completing their return themselves. Some create audit exposure. Others simply leave legitimate money uncollected.

Overclaiming and underclaiming: both cost you

Claiming 100% of a mobile phone as work-related when it’s also used personally, or claiming working from home costs without keeping records of actual hours, creates the kind of red flags the ATO’s data-matching systems are specifically designed to detect. An audit that unravels an overclaimed deduction can also disturb correctly claimed items in the same return.

Underclaiming is equally costly and far more common. Many Australians miss income protection insurance premiums, bank fees on investment accounts, or tax agent fees from the prior year, all legitimately deductible. Not claiming these items isn’t caution; it’s simply leaving your money behind.

Procedural errors that void legitimate claims

The super contribution notice of intent is the most consequential procedural error: if you don’t lodge it and receive written acknowledgment from your fund before you file your return, the deduction is lost. It’s also worth confirming your fund accepts the notice and processes it correctly before you assume the deduction is locked in.

Other common procedural errors include claiming phone and internet costs separately while also using the WFH fixed rate (they’re already included), using estimated WFH hours rather than recorded hours (the ATO explicitly disallows estimates under this method), and not updating a vehicle logbook when work travel patterns have shifted significantly during the year.

Is it worth getting a registered tax agent to handle this?

You know what’s possible. The question is whether you want to navigate it alone or have a qualified professional in your corner.

What a registered tax agent finds that a DIY return often misses

A registered tax agent asks questions that software tools don’t. Did you work from home this year? Did you make personal super contributions? Do you hold income protection insurance? Do you have carried-forward investment losses? For anyone with employment income alongside a rental property, a side income, or significant deductible expenses, a tax agent can identify claims that outweigh the cost of the service. Tax agent fees are also deductible in the following year’s return, so the cost partially offsets itself, worth factoring into the decision.
