Can I dispute an Inland Revenue tax assessment in New Zealand myself?
Yes. New Zealand's tax disputes resolution process under the Tax Administration Act 1994 is designed to be accessible to taxpayers without legal representation. The process involves several formal steps — a Notice of Proposed Adjustment, a Statement of Position, and if needed a referral to the Disputes Review Unit or the Tax Court. Most disputes are resolved before reaching the courts.
What is a Notice of Proposed Adjustment and when should I file one?
A Notice of Proposed Adjustment (NOPA) is the document that initiates the formal disputes process with Inland Revenue. If you disagree with an IRD assessment, you must file a NOPA within four months of the date of the assessment. The NOPA must state the adjustment you are seeking, the facts supporting your position, and the legal basis for your claim. Inland Revenue also issues NOPAs when it intends to adjust your tax position.
What happens after I file a Notice of Proposed Adjustment with IRD?
Inland Revenue has two months to respond to your NOPA with a Notice of Response (NOR). If IRD rejects your adjustment, you then have two months to file a Statement of Position (SOP) setting out the facts and law you rely on in full detail. IRD then files its own SOP. After this, either party can refer the dispute to the Disputes Review Unit for an independent review before any court proceedings.
What is the Disputes Review Unit and what does it do?
The Disputes Review Unit (DRU) is an independent unit within Inland Revenue that reviews disputes after the Statement of Position phase. A DRU conference officer reviews the positions of both parties and provides a recommendation. The DRU process is free and confidential. Many disputes are resolved at this stage. If the DRU does not resolve the dispute, the case proceeds to the Taxation Review Authority or High Court.
What is the Taxation Review Authority in New Zealand?
The Taxation Review Authority (TRA) is a specialist tribunal that hears tax disputes in New Zealand. It operates similarly to a court and hears appeals from taxpayers who disagree with Inland Revenue decisions after the disputes process. TRA cases can be heard in private (unenclosed hearings) or in public. The TRA's decisions can be appealed to the High Court on questions of law.
What are the time limits I must observe in a tax dispute with IRD in New Zealand?
Time limits in the tax disputes process are strict and non-extendable in most cases. You have four months from the date of assessment to file your NOPA. After IRD issues a Notice of Response, you have two months to file your Statement of Position. Missing these deadlines generally means you lose your right to dispute the assessment. Set diary reminders immediately upon receiving any IRD assessment you intend to dispute.
Can I use the disputes process for all types of IRD assessments in New Zealand?
The disputes process applies to most types of tax assessments including income tax, GST, PAYE, and FBT assessments. It does not apply to some matters such as requests for discretionary relief, disputes about tax debt collection, or Child Support assessments. For tax debt hardship, you can apply for instalment arrangements or write-off of penalties under the Tax Administration Act at ird.govt.nz.
Does disputing an IRD assessment require notarization or legal documents?
No. The Notice of Proposed Adjustment, Statement of Position, and other disputes process documents are formal tax documents but do not require notarization or sworn affidavits. They must be submitted to Inland Revenue in writing — by post, in person, or through myIR. Templates and guidance are available at ird.govt.nz. The process is designed to be completed without a lawyer.
What can and cannot be done without a lawyer in a tax dispute with IRD in New Zealand?
Filing a NOPA, Statement of Position, and attending Disputes Review Unit conferences can all be done without a lawyer. Tax agents such as accountants are commonly used for their technical expertise in tax law. Legal representation is most valuable for Taxation Review Authority hearings or High Court appeals involving complex points of tax law or large amounts of tax at stake.
