Tax filing in New Zealand for international students is a requirement that applies from the moment you earn your first paycheck. New Zealand uses automatic tax deductions through the Pay As You Earn (PAYE) system, but that does not mean your tax affairs manage themselves. Choosing the wrong tax code, failing to apply for an IRD number, or missing the annual return deadline can leave you either owing money to the Inland Revenue Department (IRD) or missing a refund you are entitled to. This guide explains the full process.
How New Zealand’s Tax System Works for International Students
New Zealand taxes income earned within its borders, regardless of your nationality or visa type. As a student on a visa that allows part-time or full-time work, any wages, salaries, or self-employment income you earn in New Zealand is subject to income tax. Goods and Services Tax (GST) is a separate consumption tax charged at 15% on most purchases — you pay it automatically when you buy goods and services, and you generally cannot claim it back unless you register a business.
Income tax is progressive, meaning each bracket only applies to the slice of income that falls within it. There is no tax-free threshold in New Zealand — tax applies from the first dollar earned.
Income Tax Rates for the 2025–26 Tax Year (1 April 2025 – 31 March 2026)
| Annual Income (NZD) | Tax Rate | Tax on This Band (Cumulative) |
|---|---|---|
| $0 – $15,600 | 10.5% | $1,638 |
| $15,601 – $53,500 | 17.5% | $8,270.50 |
| $53,501 – $78,100 | 30% | $15,650.50 |
| $78,101 – $180,000 | 33% | $49,277.50 |
| Over $180,000 | 39% | – |
In addition to income tax, most employees pay the ACC earner’s levy — set at 1.67% for the 2025–26 year on earnings up to $152,790. These funds support New Zealand’s Accident Compensation Corporation, which covers medical costs for accidental injuries. The ACC levy rises to 1.75% from 1 April 2026.
Getting an IRD Number: Your First Step
An IRD number is a unique tax identifier issued by Inland Revenue. You cannot legally receive wages in New Zealand without one — if you work without providing your IRD number to your employer, they are required to deduct tax at the non-declaration rate of 45%. Applying as soon as you arrive (or before you depart for New Zealand) avoids this.
Which Form to Use
The correct form depends on where you are when you apply:
- If you are already in New Zealand, use the IR595 (IRD number application — currently in New Zealand). Submit online via myIR or take the completed paper form to an AA Driver Licensing Agent for identity verification.
- If you are still overseas, use the IR742 (IRD number application — offshore individual). Email the completed form and scanned ID documents to IRD. Processing takes up to 20 working days.
Once your application is processed, you will receive your IRD number within 10 working days (online) or 12 working days (paper form). Keep this number — you will use it throughout your time in New Zealand and for any future tax obligations.
PAYE: How Tax Is Deducted from Your Wages
Pay As You Earn (PAYE) is the system employers use to deduct income tax, ACC levy, and (if applicable) KiwiSaver contributions directly from your pay before you receive it. Your employer passes these deductions to IRD on your behalf. The amount deducted depends on the tax code you provide.
Choosing the Right Tax Code
You declare your tax code on form IR330 (for employees) or IR330C (for contractors). Choosing the wrong code is one of the most common reasons students either overpay or underpay tax.
- M — for your main job (use this if you have one job and do not receive benefits or a NZ student loan)
- ME — as above, but also claims the Independent Earner Tax Credit (IETC) if you earn between $24,000 and $70,000
- S, SH, ST, or SA — secondary tax codes, used if you have more than one job simultaneously
- Add the SL suffix (e.g. M SL) if you are repaying a New Zealand student loan
If you are working two jobs at the same time, use the secondary code that matches your combined income from all sources — not just the second job alone.
Independent Earner Tax Credit (IETC)
The IETC provides up to NZD 520 per year for individuals earning between $24,000 and $70,000 who do not receive Working for Families, New Zealand Superannuation, or an income-tested benefit. It phases out between $66,000 and $70,000. If you qualify, you claim it by using the ME tax code — IRD applies it automatically through PAYE.
Tax Year Dates and Filing Deadlines
New Zealand’s tax year runs from 1 April to 31 March. For most students whose only income is wages subject to PAYE and who have used the correct tax code, IRD calculates your end-of-year position automatically and issues either a bill or a refund notice — no return is required.
However, you must file an Individual Income Tax Return (IR3) if any of the following apply:
- You arrived in New Zealand partway through the tax year
- You have income from overseas sources
- You were self-employed or had contract income
- You had rental income, dividends, or interest income not already taxed at source
- You used the wrong tax code and need to correct an overpayment or underpayment
The standard deadline for filing an IR3 is 7 July following the end of the tax year. For the 2025–26 tax year (ending 31 March 2026), the deadline is 7 July 2026. If you use a registered tax agent, the extended deadline is 15 March of the following year. Late filing can result in penalties from IRD.
How International Students File Tax Returns in New Zealand
Tax filing in New Zealand for international students can be done entirely online through myIR, Inland Revenue’s secure online portal, or by paper if you prefer.
Filing Online via myIR
Register for a myIR account at ird.govt.nz if you do not already have one. Once logged in, navigate to ‘Income tax’, select the IR3 return for the relevant tax year, and complete the fields with your income details and any supporting information. Submit electronically. IRD processes the return and notifies you of the outcome — typically a refund or a notice of amounts owed — within 10 weeks.
Filing a Paper IR3
IRD posts paper IR3 forms to registered taxpayers in May each year. If you do not receive one, download the form from ird.govt.nz, complete it carefully, attach all supporting documents, and post it to IRD by 7 July. If you need an extension, request one from IRD before the deadline — do not simply miss it.
Documents You Need to File
Whether you file online or on paper, gather the following before you start:
- Your IRD number
- A summary of all income earned in New Zealand during the tax year (payslips or employer-issued earnings summaries)
- Details of any overseas income received while a New Zealand tax resident
- Bank statements showing interest earned
- Records of any business, freelance, or rental income
- Any dividend or Maori authority distribution statements
If you arrived during the year, note your arrival date carefully — income earned before you became a New Zealand tax resident is generally not taxable in New Zealand, though exceptions exist if you have previously been a NZ resident.
When Can International Students Get a Tax Refund?
A refund arises when more tax has been deducted through PAYE than you actually owed for the year. The most common situations for students are:
- Working for only part of the year (e.g., arriving mid-year or leaving before 31 March). PAYE deductions are calculated on the assumption you will work the full year — if you do not, you have likely overpaid.
- Using a secondary tax code when it was not needed, or a secondary code higher than your combined income warranted.
- Earning below the threshold at which a particular rate applies across the full year.
There is a minimum annual income threshold below which small amounts of self-employment or casual income are not taxable — the current figure is $2,340. This applies to genuinely occasional earnings such as babysitting or casual odd-jobs. It does not apply to regular employment income.
Double Taxation: Are You Taxed Twice?
Some international students receive income from their home countries while studying in New Zealand — such as scholarships, family allowances, or investment returns. In some cases, both countries may attempt to tax the same income. New Zealand addresses this through its network of Double Taxation Agreements (DTAs), which allocate taxing rights between countries to prevent double taxation.
Where a DTA applies, you can claim a foreign tax credit in New Zealand for tax already paid overseas on the same income, so that your combined tax burden does not exceed the higher of the two countries’ rates. You claim this credit on your IR3 return.
New Zealand’s Double Taxation Agreement Partners
| Country | DTA in Force |
|---|---|
| Australia | Yes |
| Canada | Yes |
| China | Yes |
| Fiji | Yes |
| France | Yes |

If your home country is not on the list, you may still have some relief through New Zealand’s domestic foreign tax credit rules, but the interaction is more complex. Check the IRD website or consult a tax agent.
Your Student Visa and Work Rights
Whether you are permitted to work in New Zealand depends on the conditions attached to your New Zealand student visa. Most full-time students at degree-level institutions may work up to 20 hours per week during semester and full-time during official vacation periods. Part-time students generally cannot work unless a specific work condition is endorsed on their visa.
Earning income beyond your visa conditions is a breach of immigration law, not a tax issue — but it will still show up in IRD records. Always confirm your work entitlements with Immigration New Zealand before starting employment.
Understanding your tax obligations is part of managing your finances as a student. For a broader overview of what it costs to live and study in New Zealand, see the guide to the cost of living in New Zealand.
Frequently Asked Questions
Do all international students have to file a tax return in New Zealand?
Not necessarily. If your only income is wages taxed through PAYE and you used the correct tax code throughout the year, IRD handles the end-of-year calculation automatically. You only need to file an IR3 return if you had overseas income, arrived or departed mid-year, were self-employed, or need to correct a tax code error.
What happens if I work without an IRD number?
Your employer is legally required to deduct tax at the non-declaration rate of 45% — the maximum rate in New Zealand. This applies to every dollar of earnings until you supply a valid IRD number and correct tax code. Any excess tax deducted can be reclaimed by filing a return, but it ties up money you could otherwise use. Apply for your IRD number before your first day of work.
Can international students claim a tax refund in New Zealand?
Yes. If you worked for only part of the tax year, used the wrong tax code, or had PAYE deducted at a higher rate than your annual income warranted, you are likely eligible for a refund. File an IR3 return through myIR after 31 March and IRD will calculate what is owed to you. Refunds are processed within approximately 10 weeks.
Is scholarship income taxable in New Zealand?
Most scholarships paid to full-time students are not taxable in New Zealand, provided they are for tuition, fees, or living expenses and do not form part of an employment arrangement. However, stipends paid as part of research or teaching contracts may be treated as income. If you are unsure, check with IRD or your institution’s finance team.
What is the difference between the IR330 and IR330C forms?
The IR330 (Tax code declaration) is completed by employees and tells your employer which PAYE tax code to apply to your wages. The IR330C (Tax rate notification for contractors) is for those working as contractors rather than employees — it specifies the withholding rate to apply to schedular payments. If you are paid a salary or hourly wage, use IR330. If you invoice for services, use IR330C.
Does New Zealand tax income I earned in my home country?
Once you become a New Zealand tax resident (generally after being present in New Zealand for more than 183 days in any 12-month period), you are taxed on worldwide income. This includes foreign earnings. However, if New Zealand has a double taxation agreement with your home country, you can claim a foreign tax credit for tax already paid there. New Zealand also offers a temporary tax exemption on most types of foreign income for the first four years of New Zealand tax residency — check your eligibility with IRD.
What if I cannot file by the 7 July deadline?
Contact IRD before the deadline and request an extension. If you have a registered tax agent, they may be able to file on your behalf under the extended 15 March deadline. Filing late without an approved extension can result in a late filing penalty — the amount depends on your total tax liability for the year.
