How to request adjustment of prepayment in MyTax – individual taxpayer

The Tax Administration will send you the prepayment decision and payment details. The amount of your total prepayments is based on an estimate of taxable income.

You can change your prepayments multiple times in a year.

If your income or deductions change or do not match the original estimate, we recommend that you ask for changes to your prepayments. The total amount of the prepayment and the time at which changes are made determine how many instalments there will be during the tax year. There can be 1–12 instalments.

You can ask for your prepayments to be changed or cancelled up until the completion of your tax assessment. Your prepayment instalments remain in effect until you receive a new decision. If you have not received a new decision by the due date, pay the prepayment in accordance with the previous decision.
