NZ Tax Refund 2026 — How to Claim, How Much, and When to Expect It

Every year, hundreds of thousands of New Zealanders receive income tax refunds — and many more are owed money but don’t know how to claim it. Refunds arise when you’ve paid more PAYE tax than your actual income required. Claiming through myIR takes minutes; unclaimed refunds are money left on the table.

Why You Might Be Owed a Refund

PAYE is deducted from your pay during the year based on an estimate of your annual income. If that estimate was too high, you’ve overpaid — and you’re owed a refund.

Common Reasons for a Tax Refund

How to Check If You’re Owed a Refund

Step 1: Log in to myIR

Go to ird.govt.nz and click Log in to myIR. If you don’t have an account, see our myIR setup guide.

Step 2: Go to Income Tax Assessments

• Click Income tax in the main menu
• Click Tax assessments
• You’ll see a list of tax years

Step 3: Open the Relevant Assessment

Click on the tax year you want to check (e.g., 2024–25 covers 1 April 2024 to 31 March 2025).

The assessment shows:

• Total income (wages, interest, dividends) as IRD has recorded
• Tax withheld (PAYE deducted by employers)
• Tax owed on that income
• Result: Refund (if you overpaid) or amount to pay (if you underpaid)

Step 4: Confirm or Update

If the assessment is correct and shows a refund:

• Click Confirm
• IRD processes and deposits the refund within 5–10 working days

If the assessment is incorrect (income is missing or wrong, deductions need adding):

• Click Update this assessment
• Make corrections — this converts it to a self-filed return

If IRD has not yet issued an assessment, you can request one or file an IR3.

Registering Your Bank Account for Refunds

Your refund can only be deposited if you have a bank account registered in myIR. Without one, IRD sends a cheque (slow and easily lost).

To register:

1. Go to Profile → Bank accounts
2. Click Add bank account
3. Enter your account number in the format: 03-0123-0123456-00
4. IRD may send a small test deposit to verify — confirm the amount

Only one bank account can be nominated for refunds at a time. Ensure it’s your current, active account.

How Much Will I Get? — Worked Examples

Example 1: Changed jobs mid-year

Sarah worked at Company A from April to August ($45,000 annualised, correctly taxed). She then worked at Company B from September onwards ($50,000 annualised).

Each employer calculated PAYE as if she worked there all year. Combined actual income: ~$38,000. But PAYE was withheld based on higher assumed annual incomes at each job.

Likely refund: $400–$900 depending on exact timing and amounts.

Example 2: Multiple jobs at the same time

James works two part-time jobs. Main job: $28,000/year. Second job: $18,000/year. Combined: $46,000.

• Main job uses code M: correctly taxed on $28,000
• Second job uses code SH (30%): correctly taxed for the combined income bracket

If James used code S (17.5%) on his second job instead of SH:

• Second job income taxed at 17.5% instead of the correct 30%
• He will owe tax at year end, not receive a refund

If James over-estimated and used code ST (33%) on his second job:

• Over-withheld all year
• Refund: approximately $700–$900

Example 3: Charitable donations

Emma donated $2,400 to Oxfam NZ and the Cancer Society during the year (both are approved donee organisations).

Donation tax credit: 33.33% × $2,400 = $800 refund

Emma needs to claim this in her myIR assessment — it’s not automatic. She uploads her donation receipts and the credit is applied to her tax bill.

Example 4: Independent Earner Tax Credit (IETC)

Tom earned $36,000 from a single job. He used tax code M, not ME. The IETC is worth up to $520/year for earners in the $24,000–$48,000 range.

Tom’s assessment will show the IETC if he claims it — it’s sometimes pre-populated, sometimes requires confirming eligibility.

Refund: up to $520 (depends on how much of the year he was eligible).

Claiming Donation Tax Credits

The donation tax credit is one of the most missed refund opportunities in NZ. You get 33.33 cents back for every dollar donated to approved organisations.

What Qualifies

Any donation to an IRD-approved donee organisation — charities registered with Charities Services NZ, schools, certain hospitals, and organisations specifically listed by IRD. Check ird.govt.nz for the donee list.

What Doesn’t Qualify

• Raffle tickets, merchandise, or goods received in exchange
• Donations to overseas charities (unless the NZ entity is specifically approved)
• Payments that are part church tithing in some structures (check with IRD)

How to Claim

1. In myIR, go to your assessment or IR3 return
2. Find the Charitable donations section
3. Enter the total amount donated during the year
4. Attach receipts from each organisation (most charities email receipts; keep these)
5. The 33.33% credit is applied to your tax bill or added to your refund

Important: You need receipts from each donee organisation. Most NZ charities will issue a receipt automatically or on request. Some issue annual summaries — ask for these in April each year.

Claiming Prior-Year Refunds (Up to 4 Years Back)

You can claim refunds going back four years. As at 2026, you can claim for:

• 2024–25 (1 April 2024 – 31 March 2025)
• 2023–24
• 2022–23
• 2021–22

How to Claim Prior Years

1. myIR → Income tax → File a return → Select the relevant year
2. Complete as you would for the current year
3. Submit — IRD processes prior-year returns the same way as current-year

If you’ve never filed a prior-year return and have been PAYE-only, your refund for that year may already be sitting in an automatic assessment you haven’t confirmed yet. Check myIR for all years going back to 2021.

What Happens if You Owe Tax Instead of a Refund

If your assessment shows you owe tax:

• This happens when you’ve underpaid PAYE — most often from using the wrong secondary tax code or having untaxed income
• Payment is due by the date shown in myIR (usually 7 February for the prior tax year, or at assessment date)
• Use-of-money interest accrues if not paid by the due date

Payment Options

• myIR direct payment (credit/debit card — surcharge applies)
• Bank transfer to 03-0049-0001100-27 with your IRD number as reference and INC as payment code
• Contact IRD to arrange a payment plan if you can’t pay in full immediately

Don’t ignore a tax bill — penalties and interest compound. A payment plan (instalment arrangement) avoids late payment penalties if arranged before the due date.

Avoiding Third-Party Tax Refund Services

Several companies (Tax Refunds NZ, taxback.com, and others) offer to claim your NZ tax refund for a fee — typically 5–15% of the refund amount.

You do not need these services. myIR allows you to claim your own refund for free in 10–15 minutes. These companies take a percentage of money that is entirely yours.

If you used a refund service in the past, you may have given them authority to act on your behalf. To cancel:

• myIR → Profile → Manage access → Remove any agent access you didn’t intend to grant
• Or contact the service directly to revoke authority

Overseas New Zealanders — Claiming Your Refund

If you worked in NZ and then moved overseas, you can still claim your NZ tax refund from anywhere in the world.

1. Log in to myIR online (works from any country)
2. Check your automatic assessment
3. Ensure a valid bank account is registered — it can be any NZ bank account (a friend’s or family member’s, with their permission, if you’ve closed yours)

Note: If you’re a non-resident for NZ tax purposes (generally after 183+ days overseas), different rules apply. Your NZ income may be subject to non-resident withholding tax rather than the standard PAYE assessment. If this applies, consult a tax agent or see IRD’s guidance on non-residents.

Tax Refund Timeframes

If your refund hasn’t arrived after 15 working days, check your bank account details in myIR and send a message to IRD via the secure messaging function.

Frequently Asked Questions

How do I know if IRD has assessed me yet?

Log in to myIR → Income tax → Tax assessments. If there’s an assessment for the 2024–25 year (or earlier), it will appear here. IRD typically issues automatic assessments between May and July each year. If nothing has appeared by August, contact IRD.

My refund is $0 but I think I should get money back. What do I do?

This usually means IRD’s records match your actual tax liability — no over or underpayment. To check: compare the income shown in the assessment to your actual income, and verify the tax withheld matches your employer payslips or P60/pay summaries. If you have unclaimed donation credits or IETC, update the assessment to claim these.

Can I get a refund if I’m also receiving Working for Families?

Yes — your income tax refund and WFF entitlements are calculated separately. However, if your actual income was lower than estimated for WFF purposes, you may receive additional WFF credits at year end (not a separate refund — it’s adjusted in your WFF entitlement). If higher, you may owe some WFF back.

What if I haven’t filed my tax return for several years?

File the most recent year first via myIR, then work backwards through previous years. IRD prefers people to come forward voluntarily rather than ignore late returns. Penalties for non-filing can be waived or reduced if you engage proactively. Call IRD on 0800 775 247 if you’re unsure how to proceed.

Is my tax refund taxable income?

No. A tax refund is a return of tax you already paid — it’s not income and is not taxed again.
