Can you lodge your tax return now? Why the ATO says wait a few weeks

Tax time opened on 1 July, and the 'lodge' button in myGov is already live. If you are expecting a refund, the pull to file on day one is real — and every year, hundreds of thousands of Australians give in to it.

The ATO's advice this year runs the other way: don't lodge yet. Not because there is anything wrong with your return, but because in early July it almost certainly isn't finished — even when it looks like it is.

The numbers behind the warning

Last financial year the ATO adjusted more than 595,000 individual tax returns through its data-matching program — corrections for income left off, or deductions that didn't hold up. Around 142,000 of those were people who lodged in the first two weeks of July and then had to amend, or had the ATO amend the return for them.

The pattern is consistent. The ATO says returns lodged before its systems can pre-fill your information are more than twice as likely to need amending. Filing early doesn't get your money to you sooner if it triggers a correction three weeks later — it usually gets you a second, slower conversation instead.

What 'tax ready' actually means

Your employer, your bank, your health fund and government agencies all report your income data to the ATO — but not instantly. Through July that information flows in and is matched to your record, and for most people it is finalised by late July. Until it lands, the pre-fill in your return is incomplete, no matter how complete it looks on screen.

There is a simple signal to watch for. Once your employer finalises your income statement, it shows as 'tax ready' in myGov or the ATO app. That is the green light. Lodging before it means typing in numbers the ATO is about to replace with the official ones — and if yours don't match, that mismatch is exactly what becomes an amendment.

The claim the ATO is watching this year

Working-from-home deductions are on the ATO's radar again. For the 2025–26 year you can use the fixed-rate method — 70 cents for every hour you actually worked from home — but only if you have a genuine record of those hours. An estimate, or a 'four weeks looks about right' guess applied across the year, is not accepted.

And the hours have to be real work. The ATO has been explicit that checking a few emails or taking the odd call from the couch doesn't turn a day into a working-from-home day. Claim the hours you can substantiate, keep the diary or roster that proves them, and it is a clean deduction that stands up.

One thing not to confuse

You may have read that the tax rate on the $18,201–$45,000 band dropped from 16% to 15%. That cut applies to income earned from 1 July 2026 — the year you are in right now — not to the 2025–26 return you are about to lodge. It will not change this year's refund; it shows up in next year's. Getting the two years straight in your head saves a lot of misplaced expectation.

Waiting until late July isn't procrastination — it is the cheapest insurance in the tax calendar. Let the pre-fill finalise, confirm your income statement is 'tax ready,' and lodge against complete data once.

If your return has moving parts — an investment property, overseas income, a side business, or a year with more than one employer — that is exactly when a registered agent earns their fee: not by lodging faster, but by lodging correctly the first time. That is what our individual tax return service is for, and the right season to talk is now, before you file.
