Key-Person Insurance Tax in NZ: Deductible Premiums, Taxable Payouts

Are key-person premiums deductible and is the payout taxed in NZ? It all turns on one thing — IRD's revenue-versus-capital test. Here is how the test works, with a decision flowchart and the records your accountant needs.

Business owners ask two questions about key-person insurance almost in the same breath: can we claim the premiums as a business expense, and will Inland Revenue tax the money if we ever claim? It is tempting to want a yes to both. The honest answer is that the two are linked, and they usually move in opposite directions. The single thing that decides both is the purpose of the cover, tested against a long-standing rule called the revenue-versus-capital distinction.

Small businesses — those with fewer than 20 employees — make up around 97% of all New Zealand enterprises and contribute roughly 42% of the country's economic value ⁵⁶. These are exactly the firms most exposed to losing one person who drives the revenue, holds the key relationships, or simply is the business. This guide explains when a key-person premium is deductible, when a payout is taxable, and how to document the purpose so your tax position holds up.

TL;DR: It depends on purpose. If the cover replaces lost taxable profit (revenue purpose), the premium is generally deductible and the payout is generally taxable. If it protects capital — repaying a loan or funding a buyout — the premium is generally non-deductible and the payout generally tax-free. A taxable payout would be taxed at the company rate of 28% ¹. You cannot have it both ways.

Are key-person insurance premiums tax deductible in New Zealand?

There is no special "key-person insurance" line in the Income Tax Act. The premium is treated like any other business expense, and businesses are taxed on income minus deductible expenses ². So the premium is deductible only if it passes the same test every business cost has to pass: is it a revenue (income-earning) expense, or a capital one?

That test sits in the general permission in s DA 1 and the capital limitation in s DA 2(1) of the Income Tax Act 2007. Revenue expenses are deductible; capital expenses are not ³. In plain terms:

• If the cover is there to replace lost income or profit while the business absorbs the loss of a key person and gets back on its feet, the premium has a revenue purpose and is generally deductible.
• If the cover is there to protect the capital structure of the business — repay a loan, fund a share buyout, replace a capital asset — the premium has a capital purpose and is generally non-deductible.

The catch most owners miss is the trade-off on the other side. Deductibility and taxability of the payout are two ends of the same lever. Claiming the premium as a revenue expense generally means accepting that the payout is taxable income. There is no structure that legitimately gives you a deductible premium and a tax-free payout for the same purpose.

What is IRD's revenue-versus-capital test and why does it decide everything?

The revenue-versus-capital distinction is one of the oldest ideas in tax law, and it governs far more than insurance. The leading guides Inland Revenue relies on are the Hallstroms and Nchanga principles: capital is the cost of creating, establishing, acquiring or enlarging the permanent structure of a business, while revenue is the cost of using that structure to earn income day to day ³.

To apply that to a real expense, IRD and the courts work through the five BP Australia indicia, summarised by the Court of Appeal in McKenzies ⁴:

No single factor is decisive; IRD weighs them together. But for key-person cover the first one — the need or occasion — usually does most of the work. Ask honestly what the policy is for, and the rest tends to fall into line. That is why "why are we buying this cover?" is a tax question as much as a protection one, and why it pays to settle it before the first premium is paid rather than argue it at claim time.

When is a key-person payout taxable income?

Follow the purpose through and the payout side is the mirror image of the premium side.

• Revenue-purpose payout (income replacement). If the cover existed to replace lost profit and the premiums were deducted, the lump sum is generally assessable income in the year it is received. For most companies that income is taxed at the flat company rate of 28% ¹.
• Capital-purpose payout (loan repayment or buyout). If the cover existed to protect capital and the premiums were not deducted, the payout is generally not taxable income. It is a capital receipt, used to clear a capital liability.

A consequence worth planning for: if the payout is taxable, the gross sum insured is not what the business keeps. A revenue-purpose payout of, say, $500,000 leaves roughly $360,000 after company tax at 28% ¹. If the business genuinely needs $500,000 of after-tax income to bridge the gap, the cover has to be sized with the tax in mind. Sizing the sum insured is its own exercise — our guide on how much key-person cover you need works through it.

How does the tax treatment change if the cover repays a business loan?

This is the most common mix-up. Cover arranged to repay a business loan is almost always capital purpose: the loan is part of the business's capital structure, and clearing it is a capital outcome. So the premium is generally non-deductible and the payout generally tax-free — the opposite of income-replacement cover.

The loan itself sits separately in the tax picture. For most companies, interest on business borrowing is deductible under s DB 7 of the Income Tax Act 2007 without having to pass the usual nexus test ⁷. But that deduction is about the interest on the loan, not the premium on the policy protecting it. The two are different costs with different rules. Repaying the loan principal with an insurance payout does not create a deduction, and it does not, on its own, create taxable income either.

Because loan protection is a capital job and income replacement is a revenue job, the cleanest approach is usually to keep them as separate, clearly-purposed policies rather than one vague "business cover". We work through the debt side in business loan protection in NZ. Smiths Financial does not provide tax or accounting advice — confirm the treatment with your accountant before relying on it.

Does it matter whether the company or shareholder owns the policy?

Ownership matters, but it does not override purpose. Who owns the policy affects where the payout lands and how cleanly it can be applied — it does not by itself convert a capital-purpose premium into a deductible one.

• Company-owned cover keeps the premium and any payout inside the business. For revenue-purpose key-person cover this is the usual structure: the company pays a deductible premium and receives the (taxable) payout to shore up its own cash flow.
• Shareholder- or trust-owned cover is more common where the purpose is capital — a buyout, for example — because the proceeds may need to sit outside the company to do their job. The premium is generally non-deductible regardless.

What you cannot do is rely on the ownership label to argue a purpose the facts do not support. If a company owns and deducts a premium but the cover is really there to fund a share buyout, the deduction is exposed and the intended tax-free payout may be in doubt. The ownership, the purpose and the documentation all need to point the same way, which is why this is set up alongside your accountant and lawyer rather than chosen by default at application.

How do you document the policy purpose so IRD agrees with your claim?

Because everything turns on purpose, the purpose has to be evidenced — not assumed. IRD's position under s DA 1 and s DA 2(1) is judged on the facts at the time, so the paperwork that establishes purpose should exist from day one, not be reconstructed after a claim ³.

In practice, well-documented cover usually has:

• A board minute or owners' resolution recording why the cover is held — income replacement, loan repayment, or buyout — and the sum insured tied to that purpose.
• The accounting treatment lined up with the stated purpose — revenue-purpose premiums expensed and deducted; capital-purpose premiums not deducted — so the accounts and the intent agree.
• Sum insured reasoning on file linking the cover amount to lost profit, a loan balance, or a share value, rather than a round number.
• A review trail showing the cover was checked as the business changed, since purpose and amount can drift over a few years.

The figure below shows the decision in one path.

How is this different from shareholder buy-sell cover for tax?

Key-person cover and buy-sell (shareholder protection) cover are easy to lump together, but for tax they usually sit on opposite sides of the line.

Buy-sell funding is a capital exercise: the surviving owners are acquiring an asset (the shares), so the cover behaves like capital-purpose protection. That is precisely why mixing buy-sell funding into a "key-person" policy that is being deducted can create the worst of both worlds — a deduction that may not hold and a payout that arrives the wrong size. We cover the ownership and agreement side in shareholder protection and buy-sell agreement funding. It is also worth keeping employer costs like KiwiSaver and ESCT on employer contributions clearly separate in the accounts, since they follow their own rules.

What records should your accountant keep at claim time?

When a claim happens, the tax treatment will be tested against what the business can show. The records that matter are the ones that establish purpose and tie the numbers together:

• The policy schedule and wording, showing the insured person, the sum insured and the cover type.
• The original board minute or resolution recording the purpose when the cover was put in place.
• The accounting history of the premiums — deducted or not — consistent with that purpose across every year the policy ran.
• The basis for the sum insured (profit calculation, loan balance, or share valuation) and any reviews of it.
• The application of the payout — where the money went and what it cleared — matching the stated purpose.

If the premiums were deducted as a revenue expense, expect the payout to be returned as income; if they were never deducted because the cover was capital, the file should show that consistency. Clean, contemporaneous records are what let your accountant defend the position without arguing it from memory.

Frequently asked questions

Are key-person insurance premiums tax deductible in New Zealand?

Sometimes. There is no special rule — the premium is deductible only if it is a revenue (income-earning) expense under s DA 1 and not caught by the capital limitation in s DA 2(1) ³. Cover held to replace lost trading profit is generally revenue-purpose and deductible. Cover held to repay a loan or fund a buyout is generally capital-purpose and non-deductible. The purpose decides it.

Is a key-person insurance payout taxable in NZ?

It mirrors the premium. If the cover was revenue-purpose and the premiums were deducted, the payout is generally taxable income — for most companies at the flat 28% company rate ¹. If the cover was capital-purpose and the premiums were not deducted, the payout is generally a tax-free capital receipt. You generally cannot have a deductible premium and a tax-free payout for the same cover.

Can we deduct the premium and still get a tax-free payout?

Not for the same purpose. Deductibility of the premium and taxability of the payout are linked through the revenue-versus-capital test ³. Treating a premium as a deductible revenue expense generally accepts a taxable payout. A business can hold separate policies for separate purposes — one revenue, one capital — but each follows its own treatment.

How much tax would the company pay on a taxable payout?

A taxable, revenue-purpose payout received by a company would generally be taxed at the flat company income-tax rate of 28% ¹. So a $500,000 taxable payout leaves roughly $360,000 after tax. If the business needs a particular after-tax amount to bridge the gap, the sum insured has to be set with that in mind.

Does owning the policy through the company make the premium deductible?

No. Ownership affects where the payout lands, not whether the premium is deductible. Deductibility still turns on purpose — a capital-purpose premium is generally non-deductible even if the company owns the policy ³. Ownership, purpose and documentation all need to point the same way, which is best set up with your accountant.
