Simplifying provisional tax is something we are always working on. Our new provisional tax calculator helps you by removing the time and strain of calculating your provisional tax payments.

Update: See below our live calculator walkthrough

Key developments

  • This is a new tool to calculate provisional and terminal tax liabilities. As we detail below, you just need a few details to work out what your provisional tax payments are.
  • We help you choose the best time to file. Toggle potential tax filing dates to see if there’s an impact on your tax bill. 
  • One step payment arrangements. Once you know the liability, you can set up a payment plan with Flexitax®.

The information you need to use the provisional tax calculator

All that you require is:

  • Your IRD number
  • Your residual income tax (RIT) for your last two tax years, the dates the income tax returns for those years were filed and the expected/final RIT for the current year.
