This includes income that will be taxed before you get paid like salary or wages. Use the amount before tax.

You can use our Tax on annual income calculator to work out how much residual income tax (RIT) you'll pay.

Work out tax on your yearly income

Take away any PAYE and other income tax credits you’ll be entitled to. The remaining amount is your estimated residual income tax. This is your provisional tax for the year.

You’ll need to tell us how much residual income tax you expect to pay. You can estimate:

• using the Estimate provisional tax service in myIR
• sending us a message in myIR
• by calling us
• by writing to us.

You can estimate your residual income tax as many times as you like up until your final instalment due date.

• If you’re estimating before your first due date, then divide your residual income tax by 3. If you have a standard balance date of 31 March, your 3 equal instalments will be due on 28 August, 15 January and 7 May.
• If you're a 6-monthly GST filer, divide your residual income tax by 2. You'll pay 2 equal instalments when your GST returns are due.

Pay your instalments in full by the due dates. If the payments are late, you may get penalties and interest.
