NZ tax blog

IRD-sourced reference content for New Zealand individuals, sole traders and small businesses.

How we write

Every blog post on TaxAccountants.co.nz is written to the same rule-set:

Each $ figure, % rate, threshold and due date is sourced from a public NZ authority — IRD, ACC, Companies Office, Charities Services or legislation.govt.nz — and the source is linked at the bottom of the post.
Each cited fact carries an ISO "verified" date. When a post has not been re-checked in 90 days we flag it; past 180 days an audit script blocks it from publishing.
We do not use prohibited superlatives that violate the Fair Trading Act 1986. See our methodology page for the full list and rule-set.
We do not give tax advice. Tax advice is provided by CAANZ-member Chartered Accountants and IRD-registered tax agents. Every post ends with a referral to our partner firm, Lynch & Associates, who do.

Posts are written by the TaxAccountants.co.nz editorial team and reviewed against the IRD source pages quarterly. If you spot a stale rate or a broken link, email hello@taxaccountants.co.nz.
