Provisional tax, explained for agents

2 Apr 2026 · Realty AI

Provisional tax confuses a lot of self-employed agents, but the idea is simple: instead of one big bill at year end, you pay your income tax in instalments through the year.

How it works

Once your tax to pay passes a threshold in a year, Inland Revenue expects you to pay the next year in instalments — usually three. Each instalment is an estimate toward your eventual bill.

Why agents feel it

Because commission is variable, a big year pushes your provisional payments up — and they can land in a slower season. Planning for the dates is everything.

  • Know your instalment dates in advance
  • Keep the cash set aside so dates are non-events
  • Re-estimate if your year is tracking very differently

Realty AI tracks your provisional dates and tells you what to pay and when — no letters that catch you out.
