Tax and Benefits Checklist After a Death in New Zealand

Tax and benefits administration after a death in New Zealand sits in months two through six — after the funeral, after the initial grant applications, and after most of the immediate emotional crisis has passed. That's exactly why it gets neglected. Executors who managed the first month correctly often stall here, unsure what Inland Revenue needs, when benefit cancellations have to happen, and whether the estate needs its own tax return.

Missed IRD steps can result in overpayment debts recovered from the estate, penalties for late returns, and delays in final distribution to beneficiaries. This checklist covers the tax and benefits obligations in the sequence they should be completed.

Step 1: Cancel Government Benefit Payments to the Deceased

Before dealing with IRD, stop any ongoing payments to the deceased. If myTrove was used, some notifications may already be complete — but check each agency because myTrove does not automatically cancel all payments.

Work and Income: NZ Superannuation, Jobseeker Support, Supported Living, or any other benefit must be formally cancelled with Work and Income. Any overpayment beyond the authorized 28-day extension window becomes a debt owed by the estate. Contact Work and Income promptly and provide the identity and payment details it requests.

Veterans' Affairs: If the deceased received a Veteran's Pension or Veteran's Support payments, notify Veterans' Affairs separately. Payments belonging to the deceased cease after 28 days; ask how any continuation for a surviving spouse must be authorised.

ACC: If the deceased was receiving ongoing ACC weekly compensation or rehabilitation payments, ACC will have been notified via myTrove. Confirm in writing that all payments have stopped to avoid clawback complications.

Private insurers and employer superannuation: Cancel any employer income protection, private life insurance payments, or employer-administered superannuation that was being paid directly to the deceased. These require individual notification with a certified death certificate.

Step 2: Apply for an Estate IRD Number

The deceased's estate is a separate legal entity for tax purposes. You cannot use the deceased's personal IRD number to file estate income or distribute estate assets involving IRD.

Apply for a new estate IRD number using Inland Revenue Form IR596 (Resident non-individual). Classify the entity as a Trust/Estate. This can be done via the IRD online portal or by paper post. The IRD number is free to obtain.

You need this number to file estate tax returns and report post-death estate income. It is not a prerequisite for using Form IR625 to request release of a qualifying refund under $40,000.

Step 3: File the Deceased's Final Personal Tax Return

The executor is legally responsible for filing a final income tax return for the deceased. This return covers:

• Period: From 1 April of the current tax year through to the date of death
• Income included: All salary, wages, interest, rental income, dividends, and NZ Super received up to the date of death
• Form: Standard IR3 individual income tax return, or request a personal tax summary from Inland Revenue if the deceased's income was from wages/salary only

If the deceased is owed a tax refund and the refund is under $40,000, the executor can apply for release of those funds without probate using Inland Revenue Form IR625 (Refund Declaration). Processing takes up to 10 weeks after submission.

If the deceased had outstanding tax debt, that debt becomes a priority obligation of the estate — it must be settled before distribution to beneficiaries.

Step 4: File Estate Income Tax Returns (IR6) If Required

After the date of death, any income generated by estate assets — bank interest, rental income from a property still held by the estate, share dividends — must be reported separately using the IR6 Estate or Trust Return.

The estate IR6 covers income generated between the date of death and the date the estate is fully wound up and distributed. Most simple estates with minimal income-generating assets have a short filing period. Estates that take more than 12 months to administer, or that hold rental properties or share portfolios, may need to file multiple IR6 returns across successive tax years.

Tax treatment of estate income depends on the estate's circumstances and the type and timing of the income. Consult an accountant if the estate holds complex assets and follow Inland Revenue's current estate guidance.

Step 5: Withdraw KiwiSaver Funds

KiwiSaver balances do not automatically transfer. The executor must formally claim the funds from the KiwiSaver provider.

If the balance is under $40,000: The provider can release funds via a statutory declaration signed in front of a Justice of the Peace, solicitor, or Notary Public. The declaration states that the claimant will distribute the funds in the due course of estate administration and indemnifies the provider against future claims.

If the balance is over $40,000: The KiwiSaver provider requires formal High Court authority before releasing funds. If there is a will this is generally a Grant of Probate; if there is no will, the administrator generally needs Letters of Administration.

If there is a dispute: If multiple family members claim entitlement to the KiwiSaver balance, or if children from a previous relationship are involved, the provider may refuse a statutory declaration and require formal High Court authority. Seek legal advice before distributing the funds.

KiwiSaver funds become part of the estate on death — they do not pass directly to a nominated beneficiary in New Zealand the way they do in some other jurisdictions.

Step 6: Assess GST and Business Tax If the Deceased Was Self-Employed

If the deceased ran a GST-registered business, the executor must:

• File a final GST return covering the period up to the date of death
• Cancel the GST registration with Inland Revenue (unless the estate will continue trading)
• Notify the Companies Office if the deceased was a company director, and arrange for share transmission through the estate

An estate that continues operating a business is subject to normal business tax obligations. If winding down, the executor must formally deregister any business registrations and file final returns for all tax types.

Step 7: Distribute the Estate and Close Accounts

Before distributing estate assets, the executor should address all known IRD obligations and debts and retain enough funds for unresolved liabilities.

Distributing before settling IRD debts exposes the executor to personal liability for any tax shortfall. If the executor paid out a beneficiary before receiving an unexpected tax bill, they may be personally required to make good the deficit.

Final steps before closing:

• Obtain written confirmation from Inland Revenue that all outstanding tax matters are resolved
• Close the estate bank account once estate transactions and tax matters are complete
• File any final estate tax return covering the distribution period
• Retain records for seven years in case of future IRD audit

The Executor's Ongoing Obligation

Most executors underestimate how long the tax phase takes. A simple estate with a final personal return and a KiwiSaver claim might be wrapped up in three to four months. An estate with rental income, business interests, or share portfolios can require professional accounting support for well over a year.

The New Zealand Survivor Benefits Navigator includes the complete executor checklist for IRD obligations, KiwiSaver claim templates, and the step-by-step process for applying for an estate IRD number and filing both the IR3 and IR6 returns. It is designed for executors navigating this process without a professional accountant.
