You've Received an Inheritance in NZ: What to Do With a Lump Sum in 2026

An inheritance is not taxed on receipt in NZ, but what you do with it matters. A clear 2026 plan for debt, mortgage, KiwiSaver, investing and keeping it separate.

Receiving an inheritance is usually tied up with grief, and the worst decisions tend to get made in the first few weeks. The good news is that nothing needs to happen quickly. An inheritance is not taxed when you receive it in New Zealand, so the money is not going anywhere while you take stock. This guide walks through the order most people work in: clearing expensive debt, holding a buffer, the mortgage-versus-invest question, KiwiSaver, and keeping the money separate in a relationship.

TL;DR: New Zealand has no inheritance, estate or gift tax, so a lump sum is not taxed on receipt ¹. A common order is: park it somewhere safe, clear high-interest debt, hold an emergency buffer, then weigh paying down the mortgage against investing. If you are in a relationship, take care to keep it as separate property ³.

Is an inheritance taxed in New Zealand?

No. New Zealand has no inheritance tax, no estate duty and no gift duty. Estate duty was abolished for deaths from 17 December 1992, and gift duty was abolished from 1 October 2011, so money or assets you receive as an inheritance are not taxed on receipt ¹. It is worth knowing, because some people hold off spending or investing for fear of a tax bill that does not exist here.

There is also no general capital gains tax in New Zealand. If you inherit an asset such as a long-held family home or a parcel of shares and later sell it, the capital gain is generally not taxed ². A few exceptions are worth flagging: the bright-line test can apply to residential property, and any income the asset earns while you hold it (rent, dividends, interest) is taxable in the normal way. Tax on a deceased estate is a separate matter handled by the estate before money is distributed.

Because there is no receipt tax, there is no deadline forcing your hand. Leaving the money in a savings account or term deposit for a few months while you decide is reasonable, not wasted.

What's the smartest first move with a lump sum?

The first move is usually to do nothing irreversible. Park the money somewhere safe while the dust settles, then work through the decisions in order of what they cost you.

A rough order many people find useful:

1. Park it safely. A savings account or short term deposit keeps the money accessible and stops it being spent by accident before you have a plan.

2. Clear high-interest debt first. Credit cards, car finance, buy-now-pay-later and personal loans often charge far more than any investment is likely to earn after tax. Paying these off is a guaranteed return equal to the interest rate you were being charged.

3. Hold an emergency buffer. Many people aim for roughly three to six months of essential expenses in an accessible account. A windfall is a natural moment to top this up if it is thin.

4. Then weigh the bigger choices — the mortgage, KiwiSaver and investing — which is where the rest of this guide focuses.

The figure below sketches the same logic as a decision tree.

Should you pay down the mortgage or invest?

This is the question most people get stuck on, and there is no universal answer. It comes down to two things: the interest rate on your mortgage versus a realistic return on investing, and how soon you might need the money.

Paying down the mortgage gives you a certain, tax-free saving equal to your mortgage rate. If your home loan is at 6.5%, every dollar repaid effectively "earns" 6.5%, with no tax and no fees. Investing might earn more over the long run, but returns are not guaranteed and can fall as well as rise. The trade-off is liquidity: money put into the mortgage can be hard to get back out, whereas an investment can usually be sold.

A simple way to frame it:

In practice many people do a bit of both: clear part of the mortgage for certainty and peace of mind, and invest part for long-term growth. The "right" split depends on your rate, your timeframe and how you feel about risk, which is exactly the kind of thing personalised advice works through.

Returns are not guaranteed. The value of investments can go down as well as up and you may get back less than you invested. Past performance is not a reliable indicator of future performance. Smiths Financial does not provide advice on mortgages — for your home loan structure, speak with a mortgage adviser.

Can you put inheritance money into KiwiSaver, and should you?

You can make voluntary lump-sum contributions into KiwiSaver, and there is one clear, low-effort reason to put some in: the Government contribution. If you qualify, the Government pays 50 cents for every $1 you contribute, up to a maximum of $521.43 a year, which means contributing at least $1,042.86 of your own money between 1 July and 30 June ⁵. For most members that top-up is close to free money, so directing enough of an inheritance to capture the full amount is worth considering.

(This rate and maximum are correct as at the date below. From 1 July 2025 the match drops to 25 cents per $1 and a $260.72 maximum under Budget 2025 — check current figures before relying on them.)

The catch is access. KiwiSaver is a long-term, locked-in scheme. Savings are generally tied up until the age of eligibility for NZ Super (currently 65), with only limited early-access exceptions for a first home, significant financial hardship, serious illness or permanent emigration ⁴. So money you might need before 65 is usually better held outside KiwiSaver, where you can actually reach it.

One exception is worth naming. If the inheritance is earmarked for a first-home deposit, KiwiSaver works the other way: you can withdraw your savings to buy a first home, provided you leave at least $1,000 in the account and have generally been a member for at least three years ¹⁰. There, the job is timing the withdrawal and fund settings, not locking new money away.

A few things to weigh up about a KiwiSaver lump sum:

• Upside: the Government contribution match if you would otherwise miss it ⁵; long-term, low-fee growth; out of sight, out of mind.
• Downside: it is locked until 65 with narrow exceptions ⁴; it is an investment, not a savings account, so the balance can fall as well as rise.
• Don't conflate the two: KiwiSaver and managed funds are investments whose value can go down; they are not guaranteed and are not the same as cash in the bank.

KiwiSaver is a long-term savings scheme. Government contributions, contribution rates, withdrawal rules and tax (PIR) settings are set by the Government and can change. Figures are correct as at 4 February 2025. Check current rules at ird.govt.nz, kiwisaver.govt.nz and sorted.org.nz, and the relevant scheme's Product Disclosure Statement.

When the time comes to draw a KiwiSaver balance down rather than build it, our guide on KiwiSaver drawdown options in retirement covers how that works.

How do you keep an inheritance separate from relationship property?

This is the part people most often overlook, and it can matter more than the tax question. Under the Property (Relationships) Act 1976, property you acquire by inheritance (a "gift, devise or succession") is separate property — yours, not shared ³. But that protection is not permanent.

An inheritance can quietly become relationship property if it is intermingled with shared assets to the point that it is unreasonable or impracticable to treat it as separate ³. The classic ways that happens:

• Paying it into a joint bank account.
• Using it on the family home (for example, to pay down the joint mortgage or fund renovations).
• Mixing it with shared savings so the original sum can no longer be traced.

If keeping the inheritance separate matters to you, some practical steps people take are to hold it in an account in their sole name, avoid spending it on jointly owned assets, and keep clear records showing where it came from. Many couples also formalise the position with a contracting-out agreement (often called a "pre-nup" or Section 21 agreement), which is a legal document.

Smiths Financial does not provide legal advice on relationship property. The Property (Relationships) Act is complex and the consequences are significant — please consult a lawyer about your own situation before acting. This is general information only.

What about topping up cover, an emergency fund and a will of your own?

A windfall is a sensible moment to look at three things that often get neglected.

An emergency fund. If you do not have an accessible buffer of roughly three to six months of essential expenses, a lump sum is the easiest time to build one. It sits in a savings account, not an investment, precisely because you need to be able to reach it without selling anything at a bad moment.

Your insurance. An inheritance does not usually create a need for cover, but it is a natural review point, especially if your life has changed. Whether a claim is ever paid depends on the terms, conditions, exclusions, stand-down periods and underwriting of the specific policy, and on your disclosure, so cover is worth checking against your current situation rather than assumed to still fit.

Your own will. Going through someone else's estate is a common prompt to sort out your own. Without a current, valid will, the people you would want to benefit may not, and the process is harder for those left behind. This is a job for a lawyer, but it belongs on the list.

Whether a claim is paid depends on the terms, conditions, exclusions, stand-down periods and underwriting of the specific policy, and on your disclosure. This is a summary only — always read the policy wording or product disclosure statement. We're generally paid by commission from the insurer or provider when you take out a policy through us; this doesn't change the premium you pay, and we manage conflicts of interest in line with our duty to prioritise your interests.

When does a windfall justify getting financial advice?

Not every inheritance needs an adviser. If the sum is modest, you have no debt, a healthy buffer and a clear plan, you can reasonably handle it yourself using free resources such as sorted.org.nz. Advice tends to earn its keep when the stakes and the moving parts rise — when a windfall touches several decisions at once.

Factors that lead many people in this situation to seek advice include:

• A larger sum where the cost of getting the order wrong is meaningful.
• A mix of debt, a mortgage, KiwiSaver and investing to sequence, where the right order is not obvious.
• A wish to keep the money separate in a relationship, which has legal as well as financial angles.
• An inherited asset (a property or share portfolio) rather than cash, which raises tax and structuring questions.

Frequently asked questions

Is an inheritance taxed in New Zealand? No. New Zealand has no inheritance tax, estate duty or gift duty. Estate duty was abolished for deaths from 17 December 1992, and gift duty was abolished from 1 October 2011, so money or assets received as an inheritance are not taxed on receipt ¹. Tax on the estate itself, and any income an inherited asset later earns, are separate matters.

Should I pay off my mortgage or invest an inheritance? It depends mainly on your mortgage rate versus a realistic after-fee, after-tax return, and on how soon you might need the money. Paying down the mortgage is a certain, tax-free saving equal to your interest rate, while investing may earn more over the long run but is not guaranteed and can fall in value. Many people do some of both. Smiths Financial does not advise on mortgages — for your loan structure, speak with a mortgage adviser.

Can I put an inheritance into KiwiSaver? Yes, you can make voluntary lump-sum contributions. Contributing at least $1,042.86 between 1 July and 30 June lets you capture the full Government contribution of $521.43 if you qualify ⁵. The trade-off is that KiwiSaver is locked in until around age 65, with only limited early-access exceptions ⁴, so money you may need sooner is usually better held elsewhere. (These figures are correct as at 4 February 2025; the Government contribution changed from 1 July 2025.)

How do I keep an inheritance separate from my partner? Under the Property (Relationships) Act 1976, an inheritance is separate property, but it can become shared if it is intermingled with relationship property — for example, paid into a joint account or used on the family home ³. Holding it in your sole name, keeping records, and considering a contracting-out agreement are steps people take. This is general information; relationship property is a legal matter, so consult a lawyer.

Do I have to do anything with an inheritance quickly? No. Because there is no tax on receiving an inheritance in New Zealand ¹, there is no deadline forcing a fast decision. Parking the money in a savings account while you make a plan is a sensible first step, not a wasted one.
