What happens if I don't lodge my tax return in Australia?

Answer

If you don't lodge your tax return in Australia, the Australian Taxation Office (ATO) may apply penalties, including Failure to Lodge (FTL) penalties, and you could face prosecution. You may also miss out on a potential refund.

How it works in practice

Consequences of Not Lodging Your Tax Return

Failing to lodge your tax return by the due date in Australia can lead to several penalties from the Australian Taxation Office (ATO). The primary penalty is the "Failure to Lodge (FTL) penalty." This penalty is calculated based on how many 28-day periods, or part thereof, your return is overdue, with a minimum penalty and increasing amounts for larger entities. The ATO may also charge a general interest charge (GIC) on any unpaid tax liabilities.

Other Repercussions

Beyond financial penalties, not lodging your tax return means you could miss out on a tax refund if one is due. The ATO uses the information from your return to determine if you've overpaid tax throughout the year. Persistent non-lodgement can also lead to the ATO issuing a default assessment, which is an estimate of your income and tax liability, often higher than what you would have paid if you had lodged your own return. In severe and repeated cases, the ATO may initiate prosecution.

Impact on Future Dealings

An overdue tax return can also impact your ability to apply for loans, credit, or government benefits, as lenders and agencies often require up-to-date tax records. It's always best to lodge your tax return on time, even if you anticipate owing tax, as this allows you to manage any payment plans or seek extensions before penalties accrue.

Important exceptions

The ATO may remit or reduce penalties in certain circumstances, such as if you have a good compliance history, made an honest mistake, or faced circumstances beyond your control (e.g., serious illness, natural disaster). You can apply for a remission of penalties if you believe you have a reasonable excuse.

However, ignorance of the law or a lack of funds are generally not considered reasonable excuses.

What you should do now

  1. If you have an overdue tax return, gather all necessary income and expense documents immediately.

  2. Lodge your overdue tax return as soon as possible, even if you can't pay the tax you owe.

  3. Contact the ATO directly if you anticipate difficulties lodging or paying, as they may offer extensions or payment plans.

  4. If penalties have been applied, apply for a remission of the Failure to Lodge (FTL) penalty with a valid explanation.

  5. Seek advice from a registered tax agent to help navigate the process and ensure compliance.
