Tax Information Bulletin

Tax Information Bulletins (TIBs) contain information about changes to tax-related legislation, proposed legislation, judgements, rulings and other specialist tax topics. Inland Revenue provides the TIB as a service to people with an interest in New Zealand taxation.

Review of Public Information Bulletins

To assist taxpayer certainty and compliance, we have completed a review of all tax technical items published in Public Information Bulletins (PIBs).


The Commissioner of Inland Revenue may (or in some cases must) issue determinations about various tax issues such as accrual expenditure, depreciation, financial arrangements, foreign currency, livestock valuations, standard costs for boarding service providers, and childcare providers.

Interpretation guidelines and interpretation statements

The Commissioner of Inland Revenue issues interpretation guidelines and interpretation statements that set out her position on the matters dealt with in them.

Operational statements

An Operational Statement will set out the Commissioner's view of the law in respect of the matter discussed. They are intended to be a preliminary view in the absence of a public binding ruling or an interpretation statement on the subject.

Binding rulings

This section tells you what binding rulings are, and how to apply for a private or product ruling. It also provides information about when we can and can't give rulings.

Product rulings

Product rulings are binding rulings on how the tax law applies to a particular "product", which is an arrangement that is likely to be entered into with a number of people on identical terms.

Public rulings

Public rulings interpret how a tax law applies to taxpayers and specific types of arrangements. Taxpayers whose circumstances match those in a ruling may apply it, but are not obliged to do so.

Standard practice statements

These statements describe how we will exercise a statutory discretion or deal with practical issues arising out of the administration of the Inland Revenue Acts. Since January 2005, a new referencing system has been adopted for all new standard practice statements. Those issued in the same calendar year will be sequentially numbered and prefixed with a 2-digit year to identify the age of the publication. Standard practice statements issued prior to 2005 will retain their original references until they are replaced or re-issued.

Questions we've been asked

"Questions we've been asked" are issued by the Office of the Chief Tax Counsel. They are published items about specific tax issues that set out the answers to enquiries we have received which may be of general interest to taxpayers. A general similarity to the items will not necessarily lead to the same tax result. Each case should be considered on its own facts.

Prosecution guidelines

The Prosecution Guidelines detail the structured approach for all prosecution activity Inland Revenue undertakes.

Legal decisions - case notes

In this section you will find brief notes of decisions made by the Taxation Review Authority, the High Court, Court of Appeal, Privy Council and the Supreme Court. These case notes do not set out Inland Revenue policy, nor do they represent our attitude to the decision.
