⚡ Key Takeaways
- The Low and Middle Income Tax Offset (LMITO) — worth up to $1,500 a year — ended on 30 June 2022. More than 10 million Australians received it in its final year. There has been no replacement for 2023–24, 2024–25 or 2025–26. The ATO’s own guidance (updated April 2026) lists this as the first reason people receive tax bills. [3][2]
- The other major drivers in 2026: multiple jobs and side income causing under-withholding, HECS/HELP not disclosed to employers leading to lump-sum repayment demands, and the ATO’s expanded data-matching catching bank interest, dividends, ETF distributions and gig income that was previously “forgotten.” [3][1]
- The Stage-3 tax cuts that came into effect from 1 July 2024 (and further cuts from 1 July 2026) do not increase your refund — they simply mean less tax is deducted from each pay throughout the year. As etax.com.au puts it, the cuts “have no effect on your tax return and won’t increase your tax refund at all.” [6]
- In 2024, media reported individuals receiving surprise tax bills of $3,000–$7,000, with tax agents attributing the shock to LMITO’s end combined with unchanged withholding settings and undisclosed HECS debts. [4][1]
- Future relief is coming but not yet here. The 2026–27 Budget introduces a $1,000 standard work-expense deduction from 1 July 2026 and a $250 Working Australians Tax Offset from 1 July 2027. These will help from 2026–27 onwards — but they don’t change the reality for the 2025–26 return you’re lodging now. [10][11]
Why You Got a Tax Bill Instead of a Refund in 2026 — And How to Make Sure It Doesn’t Happen Again
By The Fine Print editorial team | Last updated: June 2026 | 13 min read | ⚠️ Not financial advice
For years, Australians could reliably expect a tax refund every July. For millions of people, that refund was baked into their annual budget — a predictable lump sum that covered a holiday, a car service, or a credit card bill. Then, quietly, the system changed. The Low and Middle Income Tax Offset ended in June 2022. No one made a big announcement. There was no new letter from the ATO. Your withholding settings stayed the same. But $1,500 of annual support silently disappeared — and the first time most people noticed was when they lodged their tax return and found a bill instead of a refund. Four financial years later, the pattern is now well established and the causes are well documented. This guide explains exactly what happened, what’s still causing bills in 2026, and three concrete steps to avoid the same problem next year.📋 What’s in This Guide
What Changed — The End of LMITO and What Replaced It
The Low and Middle Income Tax Offset was introduced in 2018 as a temporary measure and extended repeatedly until it finally ended on 30 June 2022. In its last year, it was worth up to $1,500 for individuals earning between $48,001 and $90,000, and a lesser amount for those earning up to $126,000. More than 10 million Australians received it. When it ended, it was not replaced by a direct equivalent for 2022–23, 2023–24, 2024–25 or 2025–26. [2][3]⚠️ The LMITO wasn’t visible in your pay packet. It didn’t appear as a line item on your payslip. It was quietly applied against your assessed tax when you lodged your return — which is exactly why its removal went unnoticed until refund time. People with the exact same salary, the exact same withholding, and the exact same spending suddenly found themselves with a smaller refund or an outright bill. Nothing obvious had changed. But $1,500 of hidden support had vanished. [2][4]
The ATO’s updated guidance “Why you may receive a tax bill” (April 2026) identifies this explicitly as its first reason: “A tax offset is no longer available or you are no longer eligible for a tax offset — for example, the low and middle income tax offset ended 30 June 2022.” The guidance notes this can apply even when your income and withholding settings haven’t changed — which is exactly what millions of Australians experienced. [3]Five Reasons Australians Are Getting Tax Bills in 2026
1. You lost a hidden $1,000–$1,500 boost and didn’t realise
For years, LMITO quietly inflated refunds or absorbed under-withholding. Many people got used to a $1,000–$1,500 annual refund and built it into their financial planning — treating it as reliable income. With LMITO gone and no replacement in 2023–24, 2024–25 or 2025–26, the same withholding pattern now produces a small refund, zero refund, or an outright bill. UNSW academic analysis published in October 2023 noted that millions of taxpayers were “suddenly getting bills rather than refunds” because up to $1,500 of hidden support had vanished overnight. [2][4][3]2. Multiple jobs and side income push you into under-withholding
If you work more than one job and claim the tax-free threshold on more than one of them, each employer withholds tax as though they’re your only employer — which means each withholds too little. Add in side income from gig work, freelancing, rental income, or bank interest (where no tax is withheld at source at all) and your total tax liability at year-end easily exceeds what was deducted from your pays throughout the year. SBS’s 2024 explainer specifically flagged that people with multiple jobs or who have not updated their HECS status are “especially likely to owe tax at year-end.” Media in 2024 reported surprise bills of $3,000–$7,000 for individuals with these circumstances. [1][4]3. Not telling your employer about HECS/HELP is now brutally exposed
HECS/HELP repayments are calculated on your total income across all sources — not just your main job. If you don’t tick the HECS/HELP box on your Tax File Number declaration when starting a new job (or starting a second job), your employer doesn’t withhold anything for your student debt repayment. When your return is lodged, the ATO calculates your total income, determines your HELP repayment rate, and issues a lump-sum demand for the full year’s repayment that no employer withheld. This can be thousands of dollars — appearing as a sudden bill that feels like a penalty, even though it’s simply a predictable arithmetic outcome that could have been avoided by checking a box. [1][3]4. Stage-3 tax cuts increased your pay, not your refund
The Stage-3 tax cuts (in force from 1 July 2024, with further cuts from 1 July 2026) lowered marginal tax rates, which increased take-home pay throughout the year. But lower tax rates mean less tax is withheld — which means less over-withholding to come back as a refund at year-end. Many workers saw a pay rise from July 2024 but also a lower refund (or a small bill) at tax time — and understandably felt worse off, even though their net annual position was roughly neutral. etax.com.au is explicit on this: the Stage-3 cuts “have no effect on your tax return and won’t increase your tax refund at all in the future.” [6][5]5. Data-matching means “forgotten” income now shows up
The ATO’s expanded data-matching programs in 2025–26 pull in bank interest, dividends, ETF distributions, gig-economy platform income, share sale proceeds, and rental income — and compare them to your lodged return. If you leave out that “small” term-deposit interest, the dividend from your ETF, or a few hundred dollars from Airbnb, the ATO can issue an amended assessment with the missing income added back plus a shortfall penalty and general interest charge. A small omission that would once have gone unnoticed can now flip a modest refund into a bill. [9][3]The Stage-3 Tax Cuts and the Refund Myth
One of the most persistent misconceptions in 2024 and 2025 was that the Stage-3 tax cuts would produce bigger refunds. They don’t — and can’t, by design. A tax cut reduces the rate at which tax is withheld from each pay. Over 52 weeks, that means substantially less tax is collected throughout the year. But if you actually owed that lower amount of tax, there’s less over-collection to return. For people who were relying on over-withholding to generate an annual refund, lower rates are counterproductive — they reduce the pile of money the ATO was temporarily holding on your behalf. Further rate cuts took effect from 1 July 2026 (the lowest rate dropped to 15%) with another round coming from 1 July 2027. Each round reduces over-withholding. The net financial position may be the same or better — but refund psychology takes time to adjust. [6][7][14]✅ Three Actions to Avoid a Bill Next Year
Action 1: Fix your withholding settings in myGov right now
Log into ATO Online via myGov and go to Employment. Check that only one of your jobs has the tax-free threshold ticked — if two employers are both withholding as though they’re your main job, you’re under-withheld all year. Also confirm that your HECS/HELP status is correctly recorded with every employer you currently work for. If either of these is wrong, contact your employer’s payroll team and ask them to update your withholding — they can do this via a new Tax File Number declaration. If you had a tax bill in 2024 or 2025, also ask your primary employer to withhold an additional flat amount each fortnight — typically $30 to $80 covers most side-income and HECS shortfalls, and is usually enough to convert a bill back into a modest refund at year-end. [3][1]Action 2: Stop planning around offsets that no longer exist — model your actual tax
LMITO is gone and there’s no equivalent for 2025–26. The $250 WATO doesn’t arrive until 2027–28. Stop building a refund expectation into your budget and instead calculate your real tax liability using the ATO’s tax rate tables or a reputable 2025–26-aware tax calculator. Add up all income sources: primary salary, second job, side-hustle income, bank interest, dividends and rental income. Calculate the tax on the total without assuming any automatic offset. If the result shows you’ll owe extra, start setting aside 10–20% of your side-income and second-job payments now into a separate savings account labelled for the ATO — so the bill doesn’t shock your cashflow when you lodge. [3][12]Action 3: Clean up “invisible” income before you lodge — use the ATO’s pre-fill
Before lodging your 2025–26 return, download the ATO’s pre-fill report in myTax and cross-check it against every income source you had during the year. The pre-fill should include all PAYG summaries from employers and government agencies, bank interest reported by your financial institution, share and ETF dividends and distributions, and gig/platform income reported under SERR. If any income you earned during the year is missing from the pre-fill, add it yourself — deliberately — before you submit. It is far less costly to declare income voluntarily than to have the ATO’s data-matching identify it after lodgement and issue an amended assessment with additional tax, shortfall penalties and interest. If you’re unsure what needs to be included, a quick session with a registered tax agent before lodgement is usually cheaper than fixing an amended assessment afterward. [9][3]❓ Frequently Asked Questions
Why did I get a tax bill instead of a refund?
Most likely: LMITO ended (removing up to $1,500), under-withholding from multiple jobs or side income, undisclosed HECS/HELP, or data-matched income you didn’t declare. [3][2][1]Will Stage-3 tax cuts give me a bigger refund?
No — they reduce tax withheld per pay, meaning less over-collection to return. They increase take-home pay, not refunds. [6][5]How do I fix my withholding settings?
Log into myGov → ATO Online → Employment. Ensure only one job claims the tax-free threshold and HECS status is declared to all employers. Ask payroll to withhold an extra $30–$80/fortnight if needed. [3][1]Is LMITO coming back?
No. Ended permanently 30 June 2022. The new $1,000 standard deduction (from 2026–27) and $250 WATO (from 2027–28) are separate measures and not direct replacements. [10][11]What income does ATO data-matching pick up?
Bank interest, dividends, ETF distributions, share sales, gig/platform income (via SERR), rental income and all PAYG summaries. Anything not declared can trigger an amended assessment with penalties and interest. [9][3]⚖️ The Fine Print Verdict
The shift from refunds to bills didn’t happen because Australians are doing anything wrong — it happened because a system that was quietly subsidising millions of returns for years simply stopped, with no fanfare and no immediate adjustment to withholding rates. LMITO is gone, it’s not coming back in any equivalent form until at least 2027–28, and the ATO’s data-matching is now thorough enough that the old strategy of “hope it doesn’t come up” no longer works for undeclared income. The good news is that all three causes — wrong withholding settings, undisclosed HECS, and missing income — are entirely fixable. None of them require complex planning. They require about an hour of checking, a conversation with your payroll team, and a disciplined look at your income before you lodge. If you do those three things before you lodge your 2025–26 return, next year’s tax time is unlikely to surprise you.
👉 Log into myGov now, check your withholding settings, and download your pre-fill before you lodge. It takes an hour and can save you thousands.
