When you move to New Zealand, your IRD number is one of the first practical things to organise. It is issued by Inland Revenue and is used for tax, employment, banking and some government services. This guide explains the basics in plain English so you know what to prepare and what questions to ask, without treating it as personalised tax, financial or immigration advice.
What this means for you
An IRD number is your personal tax number in New Zealand. If you plan to work, start a business, earn interest, receive rental income, apply for certain payments, or set up some financial products, you will usually need one.
For most new migrants, the practical reason is simple: your employer uses your IRD number to deduct tax from your wages under New Zealand’s PAYE system. Without an IRD number, you may be taxed at a higher non-declaration rate until your details are updated.
Tax in New Zealand is generally based on what you earn, the type of income, and your tax residency position. Immigration status and tax residency are not always the same thing. If your situation is more complex — for example, you have overseas income, investments, property, a business, or you are unsure when you become a New Zealand tax resident — it is sensible to speak with Inland Revenue or a qualified tax professional.
How it works step by step
The basic process is usually straightforward:
1. **Check whether you can apply online.** Many migrants can apply for an IRD number through Inland Revenue’s online process once they have the right identity and immigration details. 2. **Prepare your identity and visa information.** You may need passport details, immigration status information and other proof depending on your situation. 3. **Submit your application to Inland Revenue.** Inland Revenue will assess the application and issue your IRD number if the requirements are met. 4. **Give your IRD number to your employer or bank.** Your employer also needs your tax code so the correct PAYE deductions can be made. 5. **Keep your details current.** If your address, name, contact details or work situation changes, update the relevant records.
If you are planning your wider move, it helps to organise your IRD number alongside other practical tasks like banking, housing, transport and healthcare. Yimin’s [settling in New Zealand guide](/settling-in-new-zealand/) is a useful next step if you want a broader checklist.
What to prepare
Before you apply, gather your documents and key details so you do not need to pause halfway through. Exact requirements can change, so always check the current Inland Revenue instructions.
Common items may include:
- Your passport details - Your visa or immigration status details - A New Zealand address, if you already have one - Contact details such as email and phone number - Bank account details, if required for your situation - Supporting identity documents if Inland Revenue asks for them
You should also understand a few basic tax terms. **PAYE** is tax deducted from salary or wages by your employer. **Tax codes** tell your employer how much tax to deduct. **GST** is a goods and services tax that applies to many goods and services; it matters more if you run a business. **Tax residency** determines how New Zealand may tax your worldwide income, and it can require careful checking if you have income or assets overseas.
If you are budgeting for your first months in New Zealand, tax is only one part of the picture. Rent, transport, food, childcare, insurance and set-up costs can all affect your plan, so it is worth reading our guide to the [cost of living in New Zealand for migrants](/cost-of-living-new-zealand-for-migrants/).
Mistakes to avoid
The biggest mistake is assuming that immigration approval automatically sorts out your tax position. A visa allows you to be in New Zealand under specific conditions, but Inland Revenue still manages tax separately.
Try to avoid these common issues:
- **Starting work without giving your employer the right details.** This can lead to incorrect tax deductions. - **Using the wrong tax code.** If you have more than one job, student loan obligations, or other income, your code may differ from someone else’s. - **Ignoring overseas income.** Some migrants may need to consider income from overseas employment, investments, property or business activity. - **Leaving it too late.** Apply early so your IRD number is ready when you need it. - **Relying on social media advice.** Tax and immigration rules are technical and change over time.
This page is general settlement information only. For tax questions, Inland Revenue or a qualified tax professional is the right source. For immigration questions — such as whether your visa allows work, whether your partner can work, or whether your pathway can lead to residence — speak with Immigration New Zealand or a licensed immigration adviser.
Where to go next
Once your IRD number is underway, focus on the practical pieces that help your move feel stable: a bank account, housing, phone plan, transport, school or childcare if relevant, and understanding your visa conditions.
If you plan to drive, check whether you can use your overseas licence and when you may need to convert it. Our guide to [converting your driver licence in New Zealand](/settlement-converting-your-drivers-licence/) explains the basics for new arrivals.
You should also keep a folder of important documents, including your passport, visa approval, employment agreement, payslips, tenancy agreement, insurance documents, medical records, translated documents and certified copies where needed. These can be useful for everyday settlement and for future visa or residence applications.
