What this site is

NZ Sole Trader Tax is a set of independent pages about New Zealand sole trader tax dates for the year 1 April 2026 to 31 March 2027, plus a few later dates that are marked Expected or Uncertain. The editor is the site name only. There is no named author and no firm behind the pages.

What this site is not

It is not Inland Revenue and not ACC. It is not a tax agent, an accounting practice, or a financial adviser. Reading a page does not create a client relationship. Nothing here is tax, legal or financial advice.

How to read the dates

A date marked Expected follows a rule the IRD has stated, where the next official calendar was not available on 17 October 2026. The IR3 date of 7 July 2027 is in that group.

A figure marked Uncertain comes from an excerpt, a guidebook that was not read, or a table that was not transcribed. Penalties, the 8.97% interest note, six-monthly provisional dates, and the ex-GST ACC components are in that group.

What is not covered

Income tax brackets, Working for Families, KiwiSaver and the independent earner tax credit are out of scope. Public holidays are applied only where the IRD calendar we read already moved a date. Re-check the next IRD calendar and ACC rates on 1 April 2027.
