Why Is My Tax Refund Lower This Year

Making sense of a smaller refund

Your refund is the difference between the tax you paid during the year and the tax you owed after your return was checked. If that difference is smaller than last year, it's usually because one or both of those amounts changed, not because your return was done incorrectly.

Many people compare this year's refund to last year's and worry if there's a difference. But refunds are supposed to change. They depend on your income, your situation, and the ATO's rules for that year.

The most common reasons refunds shrink

There are a few common reasons why refunds end up being lower than expected.

Bracket creep

If your income has gone up, even by a small amount, more of it might fall into a higher tax bracket. This means you pay more tax overall, which can lower your refund or even lead to a bill at the end of the year.

HECS/HELP repayments

If you earn over $67,000 this year, you'll need to start paying off your HELP debt. The more you earn above that amount, the more is taken from your pay to cover it. If your income passed this threshold for the first time, or increased further past it, more of your pay goes to your HELP debt instead of your refund.

ATO data-matching

The ATO checks your return against information from employers, banks, and other third parties. If something doesn't match, they can change your assessment before it is finalised.

Offsets against other debts

If you have an outstanding balance with the ATO, or a debt with another government agency, your refund can be used to pay off that debt first. You may still be entitled to a refund on paper, but you won't necessarily see the full amount land in your account.

Lower deductions or different income

Sometimes the reason is even simpler. If you spent less on work-related items, changed jobs, or had one-off income last year that didn't happen again, your refund can be lower.

Normal variation versus a genuine problem

It's normal for your refund to change a little from year to year, and it's usually nothing to worry about. But if the drop doesn't match your situation, you get a statement you don't understand, or your refund is much lower without a clear reason, it's a good idea to check in.

The ATO's guidance on your notice of assessment explains how things like offsets, pre-fill corrections, and offset amounts can affect your result. This applies whether you lodge your return yourself or use a registered agent.

Timing can also play a part. If you lodged before your pre-fill data was complete, your original figures may not have matched what the ATO later received, which is one reason we generally recommend waiting until your income statement is marked "tax ready" before lodging.
