All Income tax dates

If you are not a provisional taxpayer but expect your residual income tax (RIT) will be more than $5,000, you may choose to be a provisional taxpayer. If you want to change the normal start date for interest, you would also need to estimate your provisional tax for that year.

Electing to be a provisional tax payer

If you are filing by paper, attach a letter to the return. If you are filing in myIR, select that you elect to be a provisional taxpayer when you file your return.

To become a provisional taxpayer, you will need to:

have paid at least $5,000 by the final instalment date (7 May for most people)
have been reasonably sure, on the day you made the 1st payment, that you would be liable to pay provisional tax for the year
send your request to be a provisional taxpayer at the same time as you file that year's income tax return.
