IRD Number Guide for Indian Arrivals in New Zealand

Step-by-step guide to obtaining your IRD (Inland Revenue Department) number in New Zealand — the essential tax identifier needed before starting work, enrolling in KiwiSaver, and filing income tax returns.

Overview

The IRD (Inland Revenue Department) number is New Zealand's primary tax identifier — an 8 or 9-digit number issued by Inland Revenue (IR) upon application. It is the New Zealand equivalent of a tax identification number and is required before you can be paid correctly by an employer, enrol in KiwiSaver, file income tax returns, or access certain government services. For Indian professionals arriving in New Zealand on an AEWV or any other work visa, obtaining an IRD number is one of the first and most time-sensitive tasks upon arrival.

The IRD number is different from the identity systems used in other countries you may have heard about. Unlike a universal social security number that gates all government services from day one, the New Zealand IRD number is primarily a tax identifier. You can open a bank account, rent a flat, access public healthcare (if eligible), and navigate most day-to-day life without one. However, every week you are employed without an IRD number, your employer is required to withhold income tax at the no-notification rate — currently 45% of all earnings — which is substantially higher than your correct marginal tax rate. This makes prompt IRD number registration a direct financial priority from the moment you start work.

This guide covers who needs an IRD number, exactly how to apply, what documents are required, how long it takes, and what to do in the meantime.

How the System Works

Inland Revenue administers the New Zealand tax system and issues IRD numbers to individuals who need to interact with the tax system — whether as an employee, a self-employed person, a KiwiSaver member, or someone receiving investment income. Every natural person in New Zealand who works, earns income, or claims any tax credit needs their own individual IRD number.

The IRD number is issued under the Tax Administration Act 1994. It is a permanent identifier — once issued, your IRD number stays with you for life. If you leave New Zealand and return years later, you use the same number. The format is either an 8-digit number (displayed as XX-XXX-XXX) or a 9-digit number (displayed as XXX-XXX-XXX).

When you start employment in New Zealand, your employer must collect your IRD number and your tax code from you. The tax code tells your employer which tax rate to apply to your income. The most common tax code for a main employment job is 'M' (main income, no student loan). If you have a student loan, you would use 'M SL'. If you have a second job, the second employer uses code 'S' or 'SH' depending on your income level. Without an IRD number, your employer cannot enter a valid tax code and must deduct at the no-notification rate.

Inland Revenue manages your tax account via myIR — the online portal at ird.govt.nz. After receiving your IRD number, registering for myIR allows you to view your tax account, file returns, update your details, manage KiwiSaver, and access Working for Families tax credits if you have dependent children.

Step-by-Step Process

Step 1: Arrive in New Zealand with a valid visa. You cannot apply for an IRD number before arriving in New Zealand. A valid New Zealand visa and a New Zealand address are required for the application.

Step 2: Secure a New Zealand address. You will need a physical address in New Zealand for the IRD number application. This can be a short-term rental, a serviced apartment, or the address of a friend or family member you are staying with initially. The address is used for correspondence and to confirm your presence in New Zealand.

Step 3: Open a New Zealand bank account (recommended, not required). Inland Revenue asks for a New Zealand bank account number on the IRD number application form (IR595). Having a bank account open before applying streamlines the process. Most major banks — ANZ, ASB, BNZ, Westpac — will open an account for a new arrival with a passport and visa. ASB has a specific international arrival program worth investigating before you land.

Step 4: Complete the IRD number application (IR595). The fastest method is the online application via the myIR portal at ird.govt.nz. You do not need an existing myIR account to apply for an IRD number — the application form is accessible without logging in. Alternatively, download and complete form IR595 and post it to Inland Revenue.

Step 5: Provide required documents. For the online application, you will upload scans of: your passport (main photo page and the page showing your current New Zealand visa stamp or entry), your visa approval letter from INZ (or your electronic travel authority if applicable), and proof of your New Zealand address (bank statement, tenancy agreement, or a letter from whoever you are staying with).

Step 6: Submit and wait. Most online applications are processed within 8–10 working days. Postal applications typically take 10–15 working days. Inland Revenue will post your IRD number to your New Zealand address. You can also check the status of your application via myIR or by calling Inland Revenue on 0800 775 247.

Step 7: Provide your IRD number to your employer immediately. As soon as you receive your IRD number, give it to your employer's payroll team along with your completed tax code declaration (IR330 form). Your employer will then apply your correct tax code, and the appropriate marginal tax rate will be used from your next pay period.

Key Rules and Constraints

Your IRD number application requires a valid New Zealand visa — tourist visas or expired visas do not qualify. Applications on certain temporary visa types may require additional documentation. Inland Revenue staff can advise on your specific visa category.

The IRD number is individual — each family member needs their own. If you are bringing a spouse or dependent children to New Zealand, each person who will earn income, receive Working for Families credits, or enrol in KiwiSaver needs their own IRD number application. Applications for children can be made by the parent.

Your IRD number is sensitive information. Do not share it with anyone except your employer, Inland Revenue, your KiwiSaver provider, your bank (for interest income reporting), and authorised tax agents. Identity theft involving IRD numbers does occur — be particularly cautious about sharing it via email or in unsecured documents.

KiwiSaver enrolment requires an IRD number. When you start a new job in New Zealand, your employer is required to auto-enrol you in KiwiSaver (unless you opt out within 56 days or are already enrolled). The KiwiSaver contribution is linked to your IRD number. If your employer cannot match your IRD number to a KiwiSaver account, contributions may be held by Inland Revenue until the number is confirmed.

Costs and Timelines

The IRD number application is free. There is no charge for obtaining your IRD number from Inland Revenue.

Online application processing time: 8–10 working days from a complete application.

Postal application processing time: 10–15 working days.

If you have not received your IRD number after 15 working days, contact Inland Revenue on 0800 775 247. Processing delays occasionally occur during high-volume periods (typically around the April tax year start).

If your employment starts before your IRD number arrives, instruct your employer in writing that you have applied and provide them with evidence of the application (such as a screenshot of the submission confirmation). Some employers will accept this and hold the excess tax deducted for correction once the IRD number is received, although they are not legally required to do so under the no-notification rule.

Common Pitfalls

Delaying the application after arrival. The most common and costly mistake is treating the IRD number as something to sort out in the first few weeks. Apply on your first full day in New Zealand — you have your passport, your visa, and your address. The 8–10 working day wait starts from the day you submit.

Using an overseas address on the application. The IR595 requires a New Zealand address for delivery of the IRD number letter. If you enter an overseas address, the processing may be delayed or the number may be sent to an address you no longer have access to.

Not providing the IRD number to your employer immediately. Receiving your IRD number and not informing your employer's payroll team quickly means continued deduction at the no-notification rate. Tax over-deducted in this way is recoverable via your end-of-year income tax assessment, but you will have less take-home pay in the interim.

Confusing the IRD number with a universal settlement number. Unlike some other countries' systems, the IRD number does not unlock healthcare eligibility, housing applications, or driving licence processing. These processes have their own requirements.

Practical Tips for Indian Professionals

Apply online via myIR rather than by post — online applications are processed faster, and you can track the status. Have your passport scan, visa approval letter, and proof of address document ready as PDFs before starting the application; the process takes under 20 minutes with documents prepared.

If you have a job start date before your IRD number arrives, speak with your employer's HR or payroll team early. Some large employers — particularly in technology, healthcare, and engineering — have processes to hold excess withholding and apply the correct rate retrospectively once the IRD number is received. Get this agreement in writing.

After receiving your IRD number, register for myIR immediately. The myIR portal is your primary interface with Inland Revenue for everything from tax code declarations to checking your KiwiSaver balance to lodging a tax return. Register at ird.govt.nz/myir.

If you have other sources of income (freelance work, rental income from Indian property, interest income), discuss these with a New Zealand tax accountant. The India–New Zealand Double Taxation Agreement (DTAA) provides relief against double taxation, but you may still need to declare certain foreign income in New Zealand depending on your residency status.

For families: apply for IRD numbers for your spouse and any income-earning dependents at the same time as your own application. Each application is independent; submit them together to minimise the delay in getting all family members onto correct tax codes before they start work.
