This website provides general information only. It is not financial advice, tax advice, investment advice or legal advice, and it does not take your personal circumstances into account.
General information, not advice
IRD Tax Guide NZ explains how New Zealand tax and Inland Revenue (IRD) processes works. Its guides are written for New Zealand taxpayers, employees, contractors, sole traders, landlords and students. We are not a tax agent or a person giving financial advice under the Financial Markets Conduct Act 2013, and nothing on this site is a recommendation, an offer, or a personalised statement of what you should do. If you need advice for your own situation, speak to a qualified professional — for New Zealand readers that means an appropriately licensed adviser (the FMA publishes consumer guidance at fma.govt.nz) or, for tax questions, a tax agent registered with Inland Revenue.
Accuracy and currency
We take care to work from official sources, but rates, thresholds, contribution percentages and deadlines change — sometimes mid-year, and sometimes with transitional rules. A page that was correct when it was written can be out of date when you read it. Always confirm the current position with Inland Revenue (ird.govt.nz), Sorted (sorted.org.nz), business.govt.nz and the Financial Markets Authority (fma.govt.nz) before making a decision, particularly where money or a deadline is involved.
Tax filing, penalties and deadlines
Tax outcomes depend on your own facts — entity structure, residency, income sources, deductions and elections. Deadlines and thresholds quoted on this site are the ones published by Inland Revenue at the time of writing; they can change, and late filing or payment can attract penalties and interest. Check your own position with Inland Revenue or a registered tax agent before you rely on a figure from this site.
No liability
To the fullest extent permitted by New Zealand law, IRD Tax Guide NZ and its publisher accept no liability for any loss, damage, cost or expense arising from the use of, or reliance on, any information on this site. Your use of the site is at your own risk.
