Why commission income needs its own tax plan

15 Apr 2026 · Realty AI

Commission does not arrive in neat monthly slices. You might bank three settlements in a fortnight and then nothing for two months. Tax planning built for a steady salary simply does not fit.

The lumpy-income trap

When a big month lands, it is tempting to treat the whole payment as spendable. But income tax, GST and ACC are all waiting in the wings. Without a plan, the bill arrives when your pipeline is quiet.

Smoothing it out

  • Estimate your effective tax rate across the full year, not per payment
  • Set aside a fixed percentage of every commission as it lands
  • Use provisional tax dates as guardrails, not surprises

We model your year and tell you the exact percentage to hold back — then keep it accurate as your sales change.
