Do you have overdue tax? Are you behind with a tax return?

In August and September 2026, we’ll be contacting groups of customers who have overdue tax over $100. Some of these customers also have overdue tax returns.

You may get a pre-recorded call or voicemail message.

If we call you, how do you know it’s not a scam? Our number 0800 951 758 will display on your phone.

The message will remind you to pay your tax or file your tax return. We’ll give you ways to contact us.

If you have any questions, please call us on 0800 951 758.
