Sold Your Business in NZ: How to Plan the Proceeds for Retirement

A 2026 guide to turning business-sale proceeds into reliable retirement income in NZ — tax, a safe drawdown rate, KiwiSaver, NZ Super and protecting the money in a relationship and your estate.

Selling a business is the end of one job and the start of another: turning a single large sum into an income that has to last the rest of your life. After years of the business being the plan, the money is suddenly liquid, visible and a little daunting. A good business sale retirement plan in NZ is mostly about structure — separating the money you'll need soon from the money you can leave invested, knowing what (if anything) is taxed, and drawing it down at a pace that doesn't run dry. This guide walks through the practical decisions, with the rules and rates as they stood in early 2026.

TL;DR: Treat the proceeds as a portfolio, not a windfall. Hold one to two years of expenses in cash, invest the rest across diversified funds, and draw down at a sustainable rate — Sorted's guidelines model 4% and 6% options ⁶⁷. NZ has no general capital gains tax, so the basic gain is usually untaxed, though some parts of a sale can be ⁵. NZ Super (about $28,868 a year after tax for a single person living alone ¹) is a base to top up, not a full income.

What changes when your business sale completes?

The day the sale settles, three things change at once. Your income from the business stops. A large sum lands in your account, often the biggest you've ever held in cash. And your money is, for the first time in years, completely liquid — which is both freeing and risky, because cash sitting idle loses value to inflation while you decide what to do.

The temptation is to act fast — pay down everything, help the family, lock something in. A calmer first step is to do very little for a few weeks beyond parking the money somewhere safe (a call account or term deposit) and getting clear on the numbers. Settlements often have moving parts — earn-outs, restraint-of-trade payments, retentions held back for a period — so the figure that lands today may not be the final figure. Mapping what's actually yours, what's still to come, and what (if anything) is taxable comes before any big decision.

How do you turn a lump sum into reliable retirement income?

The core idea is to stop thinking of the proceeds as one pile and start thinking of it as a few buckets, each with a job. A common structure for retirees looks like this:

• An emergency and short-term buffer in cash. The Retirement Income Interest Group of the NZ Society of Actuaries, referenced by Sorted, suggests retirees hold one to two years of expenses in accessible cash so you never have to sell investments in a market dip ⁷.
• A diversified invested portfolio for the medium and long term — spread across NZ and global shares, bonds and similar, sized to your timeframe and tolerance for ups and downs.
• A regular drawdown from that portfolio that tops up NZ Super to cover your living costs.

The point of the cash buffer is sequencing: if shares fall the year after you retire, you spend from cash and leave the portfolio to recover, rather than crystallising losses. People approaching retirement with a single large sum often find this bucketed approach turns an intimidating number into a manageable monthly income. How much sits in each bucket depends on your spending, your other income and how you feel about volatility — which is the heart of a retirement drawdown plan.

Is the sale price taxed in New Zealand?

New Zealand has no general capital gains tax, so the basic gain on selling a business is usually not taxed ⁵. That surprises people coming from other countries, and it's a genuine advantage of selling here. But "usually" is doing real work in that sentence, because specific income-tax rules can apply to parts of a sale ⁵:

How a sale is structured — what's sold, how the price is allocated across assets, whether it's shares or assets — changes the tax outcome, and that's an accountant's and lawyer's job, not ours.

How much can you safely draw down each year?

Once the portfolio is invested, the question becomes how much you can take each year without running out. There's no single correct figure, but Sorted (Te Ara Ahunga Ora Retirement Commission) sets out four "rules of thumb", developed with the NZ Society of Actuaries, for turning a lump sum into income ⁶:

To make these concrete, on a $1,000,000 invested portfolio the 4% Rule produces about $40,000 a year and the 6% Rule about $60,000 ⁶ — figures that illustrate the rules, not a recommendation or a prediction of what your portfolio will earn. A higher draw means more spending now but a greater chance of depleting the fund; a lower draw is more durable but leaves you living on less. The right rate depends on your age, your other income and whether you want to preserve capital for your estate or spend it down. We work through this in detail in our guide to a safe withdrawal rate in NZ.

These are illustrations based on the stated drawdown rules (Sorted / NZ Society of Actuaries), not predictions; returns are not guaranteed, the value of investments can go down as well as up, and actual results will differ. Figures correct as at 19 February 2025.

Figure: From sale proceeds to retirement income (Smiths Financial illustration) — the lump sum first has any tax set aside, then an emergency buffer of one to two years' expenses is carved off, the remainder is invested as a diversified portfolio, and an annual drawdown from that portfolio (alongside KiwiSaver, once accessible) tops up NZ Super to meet your living costs.

What role should KiwiSaver and other funds play now?

If you have a business sale lump sum, it's easy to overlook KiwiSaver — but it stays useful, especially before and around age 65. KiwiSaver is a tax-advantaged retirement vehicle, and if you're still under 65 and have any earned income, contributing keeps you eligible for the Government contribution: up to $521.43 a year, paid as 50c per $1 you put in, up to $1,042.86 of your own contributions, for the KiwiSaver year then running ⁸. The minimum employee and employer rate was 3% of gross pay at that time ⁹. (Both of those settings changed later in 2025 and 2026 — see the note below — so check the current figures before acting.)

Once you reach 65, KiwiSaver becomes another invested pot you can draw from, sitting alongside the rest of your portfolio. For many recent business owners, the practical move is to treat KiwiSaver, any non-KiwiSaver managed funds, and the newly invested sale proceeds as one coordinated portfolio with a single drawdown plan, rather than three separate accounts pulling in different directions. Named NZ providers such as Milford, Booster, Fisher Funds, Generate, Simplicity and Kernel all run funds across the risk spectrum at different fees and styles; the right mix depends on your timeframe and temperament, which is what a KiwiSaver and retirement review is for.

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 19 February 2025 — note the Government contribution was halved to $260.72 from 1 July 2025, and minimum rates are rising to 3.5% from 1 April 2026 and 4% from 1 April 2028. Check current rules at ird.govt.nz, kiwisaver.govt.nz and sorted.org.nz, and the relevant scheme's Product Disclosure Statement.

How do you protect the proceeds in a relationship and your estate?

A large sum sitting in one person's name is also a planning question, not just an investment one. Under the Property (Relationships) Act 1976, relationship property is generally split equally (50/50) after a qualifying relationship of three years or more ¹⁰. Business sale proceeds can become relationship property unless they're kept separate and protected — which is why people in this situation often look at a contracting-out ("section 21") agreement, the formal version of a prenup, and clear, up-to-date wills.

The estate side matters too. A windfall changes what your will and any trusts should say, who's named as beneficiaries on accounts and policies, and whether your enduring powers of attorney are current. None of this is our area to advise on, but it belongs on the checklist so a good outcome on the sale isn't undone later.

Smiths Financial does not provide legal or estate-planning advice. This is general information only — please consult a lawyer about relationship-property agreements, wills and trusts.

What cover do you still need once you're no longer working?

Leaving work changes your insurance picture. Income protection, which replaces a portion of earned income, generally has no purpose once you no longer earn a wage — many people cancel it at retirement. But other needs can remain. Health insurance often matters more in later life, when elective procedures can carry long public waiting times, and keeping a long-held policy avoids new underwriting on conditions you've developed since. Some people keep a modest amount of life cover for estate liquidity or to leave a defined sum, while others self-insure from the proceeds instead. There's no universal answer — 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 any change is worth reviewing properly rather than cancelling on autopilot.

Common mistakes owners make with the windfall

A few patterns come up again and again when a sale completes:

• Spending fast before the plan exists. Big commitments made in the first weeks — a property, generous gifts, a new venture — are hard to unwind and can shrink the income base permanently.
• Leaving it all in cash. It feels safe, but inflation erodes a large cash balance every year it sits undeployed.
• The opposite — chasing high returns. Putting the whole sum into one aggressive bet, a single property, or a friend's start-up swaps one concentrated risk (the business) for another.
• Ignoring the tax detail. Assuming "no capital gains tax" means "nothing is taxable", when trading stock, depreciation recovery and restraint-of-trade payments can be ⁵.
• Forgetting NZ Super. From age 65 it's not income- or asset-tested for most people, so your investment income doesn't reduce it ⁴ — it's a reliable base layer worth planning around, paid fortnightly ³.
• Skipping the relationship-property and estate paperwork, leaving a large sum exposed ¹⁰.

The thread through all of these is structure before action. A windfall handled like the inheritance it functionally is — see our guide to making the most of a lump sum — tends to do far more for a retirement than one spent in a hurry.

Frequently asked questions

Do I pay tax when I sell my business in New Zealand?

There's no general capital gains tax in NZ, so the basic gain is usually not taxed ⁵. However, specific parts of a sale can be taxable — trading stock, depreciation recovered on plant and equipment, accrued income, restraint-of-trade payments, and land bought to resell ⁵. How the deal is structured affects the outcome, so confirm the tax treatment with your accountant before relying on any figure.

How much can I draw from the proceeds each year without running out?

Sorted's guidelines set out four options — a 6% rule, a 4% rule, an inflation-adjusted 4% rule, and a life-expectancy-based rule ⁶. On a $1,000,000 portfolio the 4% rule gives roughly $40,000 a year and the 6% rule roughly $60,000 ⁶. A lower rate lasts longer; a higher rate gives more income now but a greater chance of depleting the fund. The right rate depends on your circumstances.

Will my investment income reduce my NZ Super?

For most people, no. NZ Super is paid from age 65 and is not income- or asset-tested for most retirees, so income from your invested proceeds generally doesn't reduce it ⁴. It's paid fortnightly and taxed at the 'M' code when it's your main income ³. For a single person living alone it was about $28,868 a year after tax in early 2026 ¹ — a base to top up, not a full income.

Should I keep contributing to KiwiSaver after selling?

If you're under 65 with some earned income, contributing keeps you eligible for the Government contribution — up to $521.43 a year as at the post's date, on at least $1,042.86 of your own contributions ⁸. That figure was later halved, so check the current amount. After 65, KiwiSaver simply becomes another invested pot to coordinate with the rest of your portfolio under one drawdown plan.

How do I keep the money safe in a relationship?

Relationship property is generally split 50/50 after a relationship of three years or more under the Property (Relationships) Act 1976 ¹⁰. Sale proceeds can become relationship property unless protected — many people use a contracting-out ('section 21') agreement and update their wills. This is a matter for a lawyer; we can't advise on it, but it belongs on the checklist.

How much should I keep in cash versus invested?

A common approach is one to two years of living expenses in accessible cash as a buffer, with the rest invested in a diversified portfolio ⁷. The cash buffer means you can ride out a market dip without selling investments at a low point. The exact split depends on your spending, your other income and how comfortable you are with short-term ups and downs.
