What happens if you are a little late on taxes?
Quick Answer
Yes, being late on your taxes in Australia has real consequences. The ATO applies automatic penalties (Failure to Lodge penalty), charges interest (General Interest Charge), and can take enforcement action including garnishing wages or intercepting tax refunds. The sooner you lodge and pay, the less it will cost you.
What Happens If You Are Late on Your Taxes
Being even a few days late on your tax obligations in Australia is not a trivial matter. The Australian Taxation Office (ATO) operates an automated penalty system that kicks in the moment your return or activity statement becomes overdue. There is no grace period — the penalties start accumulating from day one.
Failure to Lodge (FTL) Penalty
The primary penalty for late tax returns is the Failure to Lodge on time penalty. This is applied automatically by the ATO’s systems and is calculated as:
- $312 per 28 days (or part thereof) that the return remains un lodged
- Cap of 5 penalty periods, totalling $1,560 per return
This penalty applies to income tax returns, activity statements, and other document lodgments. It is purely administrative — the ATO does not need to issue a manual notice for it to apply.
General Interest Charge (GIC)
On top of the FTL penalty, if you owe tax and do not pay by the due date, the ATO charges the General Interest Charge. The GIC is a compounding daily interest rate set by the ATO. As of the 2024-25 financial year, the GIC rate sits at approximately 11.38% per annum — this is significantly higher than typical bank interest rates and compounds daily.
For example, if you owe $5,000 in tax and pay 90 days late, you would accumulate approximately:
- GIC: ~$140 for 90 days at 11.38% p.a.
- FTL penalty: $312 (one 28-day period)
- Total additional cost: ~$452 on top of the original $5,000 owed
Impact on Future Refunds
If you are owed a tax refund, the ATO may use it to offset any outstanding tax debts, activity statement liabilities, or other ATO-administered debts. This means your refund could be reduced or eliminated entirely if you have prior outstanding lodgments or debts.
Enforcement Actions
If you consistently fail to lodge or pay, the ATO can escalate enforcement, including:
- Director Penalty Notices (DPNs) — for company directors who fail to meet PAYG withholding obligations
- Garnishee notices — directing third parties (such as banks or employers) to pay money owed to the ATO
- Legal action — court proceedings to recover the debt
- Personal insolvency — in extreme cases, the ATO can initiate bankruptcy proceedings
The “ReasonableExcuse” Escape Hatch
The ATO can remit FTL penalties if you have a reasonable excuse. However, you must demonstrate that:
- The circumstance was genuinely beyond your control
- You acted promptly once the circumstance was no longer an issue
- You had no awareness (or reasonably should have had no awareness) of the obligation
Acceptable excuses typically include natural disasters, serious illness, or being overseas without access to records.
What To Do If You Are Already Late
If your tax is already overdue:
- Lodge immediately — stopping further FTL accumulation
- Contact the ATO — before they contact you
- Set up a payment plan — the ATO offers structured payment plans for genuine financial hardship
- Request remission — if you have a reasonable excuse, lodge a request to have penalties remitted
Summary
Being late on your taxes costs money — in FTL penalties ($312 per 28 days, up to $1,560) and GIC interest (currently ~11.38% p.a., compounding daily). The ATO has enforcement powers that can escalate to legal action and insolvency. If you are behind on lodgments, act now: lodge and pay as soon as possible, and contact the ATO proactively to discuss payment options or penalty remission.
