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

On 10 and 17 March, we’ll be contacting about 2,000 customers who have overdue tax of over $100, or 1 overdue income tax return.

The taxes involved are:

  • GST
  • income tax
  • employer payments (like PAYE).

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 income tax return. We’ll give you ways to contact us.

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