If your company's end of year balance date is 31 March, then your tax return was due on 7 July – unless you’ve been granted an extension of time.

If you have a balance date other than 31 March, the due date might be different. If you’re unsure, you can contact us for more information.

If your company has a tax agent, you may have until 31 March 2022 to file your return. Talk to your tax agent to learn more.

Note: If you're registered for GST, you'll need to file a GST return as well as an IR4. The due date for your GST return will depend on your filing frequency.

Times are tough for businesses right now with the continued impacts of COVID-19. While income tax payment is not required until the prescribed dates, you are still required to file your returns. Continuing to file ensures your information is up-to-date and accurate. It will also help support any applications you make for the Government's COVID-19 relief packages.

If COVID-19 has impacted your ability to pay, there are ways we can help. Including, by setting up an instalment arrangement to pay off your tax over time. You can set up an instalment arrangement in myIR. Or send us a message in myIR to explain the situation and we'll take that into consideration. You will not be charged penalties and interest if you keep to the terms of the arrangement to pay off the outstanding tax. Get in touch as soon as you can.
