Check your ACC levy invoice — the check is free, always

Before you start

Go and get these — it makes the rest quick

Two minutes with the invoice in front of you saves ten minutes of guessing.

Your ACC levy invoice: The five-digit classification unit — near the top, under a heading that says "Classification unit"
The date on the invoice — it starts a three-month clock that matters later
The earnings figure the levy was charged on — ACC calls it liable earnings
Roughly when your business changed: Month and year is enough — ACC reassesses from a date, so there has to be one

On a phone? Write the numbers down, or have the document next to you on paper. Swapping between tabs while holding a figure in your head is where people lose their place.

No invoice to hand? Every check still runs on what you do know, and we will tell you exactly which figure was missing and what it would have unlocked.

Takes a few minutes, saves as you go, and you can stop and come back. Checking is free whatever it finds.

The detail, if you want it

How the pricing works: every check and the full result are free, including "nothing found". You only ever see a price if a check finds money owed — and then only if you want it all filled in for you, with a plain guide telling you exactly what to send, where, and in what order ($17.95 self-employed / $39 employer). No finding, no charge, ever.

Businesses change; classifications don't follow by themselves. A builder who now only designs, a manufacturer who now imports, a workshop that became an office — each keeps paying the hands-on rate until someone tells ACC. There is also a set of purely arithmetic mistakes (income caps, part years, redundancy in the earnings figure) that need no judgement at all.

Your answers stay on this device. The result — including whether we found nothing — is free. How it works, in detail.

Look up a classification unit

Every levy invoice is priced off one classification unit. The classification unit reference carries the current rate, the rate history, every BIC code that maps to the unit and written notes on the units it gets mistaken for — for the thirty units where the mistake is most common and most expensive.
