If Key Person Premiums Are Deductible, the Payout Is Taxed

The honest answer to whether key man insurance is tax deductible in the UK is: sometimes, and if it is, the payout is taxed too. HMRC ties the two together deliberately. Where a company is allowed to deduct the premiums as a business expense, the money it receives when the policy pays out is generally treated as taxable trading income. Claim relief on the way in, and you usually pay tax on the way out. Broker pages that promise the deduction and stop there leave out the second half of the sentence.

This matters for a practical reason that goes beyond tidy accounting. If the payout will be taxed, the sum the company actually receives is smaller than the sum assured, and a business that insured for exactly what it needed will find itself short by the tax. The figure has to be grossed up to allow for that, or the cover does not do the job it was bought for. So the question is not just "can we deduct the premiums" but "which side of HMRC's line does this policy sit on, and what does that do to the amount we need to insure for."

Here is what decides whether key person premiums are deductible, why so many owner-manager policies fail the test, and what the reciprocity between relief and tax means for the number you write on the application.

The short answer: relief on the way in, tax on the way out

HMRC does not treat the premium and the payout as two unrelated events. It treats them as two ends of the same arrangement. The logic is straightforward: if the cost of the cover was allowed to reduce the company's taxable profit, then the benefit of the cover — the money that comes in on a claim — should be brought into taxable profit too. Symmetry, in other words. You cannot generally have the deduction and a tax-free receipt at the same time.

The reverse is also true, and it is the part people forget. Where the premiums are not deductible, the proceeds are not normally taxed. So there is no universally "best" answer. A policy set up to protect the company's profits and structured to get the deduction leads to a taxable payout; a policy set up to protect a loan or a shareholding, which typically does not get the deduction, leads to a payout that is not taxed. What you must not do is assume you get the good half of both — relief on the premiums and a tax-free lump sum — because that combination is exactly what the rules are designed to prevent.

When key person premiums can actually be deducted

The conditions HMRC applies are long-standing; they trace back to a statement made in Parliament in 1944 and are set out today in the department's own guidance. You can read them in HMRC's Business Income Manual at BIM45525, which is the reference an accountant will actually turn to. In broad terms, a premium stands a chance of being deductible where all of the following are true.

• The relationship is purely employer and employee. The insured person has no substantial proprietary stake in the business — they are covered because they are a valuable employee, not because they are an owner.
• The policy meets a loss of profit, not a capital loss. It is there to cover the fall in trading income caused by losing the person's services, rather than to repay a loan or buy out a shareholding, which are capital purposes.
• It is short-term term assurance. An annual or short-term policy with no investment element, taken out to cover the risk over a defined period, rather than a whole-of-life or savings-type contract.

Even where all three are met, the deduction is not automatic. It still has to satisfy the general "wholly and exclusively" test — the premium must be incurred wholly and exclusively for the purposes of the trade — and an inspector can look at the facts of the individual case. The conditions open the door; they do not guarantee you walk through it.

Why owner-manager policies so often fail the test

Here is the awkward reality for the typical small company. The person a small business most wants to insure is usually the owner — the director who holds most or all of the shares and generates most of the profit. And that is precisely the person the deduction rules tend to exclude.

The first condition is the sticking point. If the insured person has a substantial stake in the business, the relationship is not purely that of employer and employee — they are an owner as well — and the premiums are unlikely to be deductible on the profit-protection basis. Many one-person and family companies fall at this hurdle without realising it, because the whole point of the cover, for them, is to insure the owner.

The purpose condition catches others. A great deal of what small companies call key person cover is really there to repay a bank facility or to fund the purchase of a deceased owner's shares. Those are capital purposes, not loss-of-profit purposes, so again the premiums usually are not deductible. That is not a failure of the policy; it just means it sits on the non-deductible side of the line, where, importantly, the payout is not taxed either. How much cover an owner-manager needs is itself complicated by the way many of them are paid — a question we look at in whether a low salary and high dividends limits the cover you can get — but the deductibility question turns on stake and purpose, not on pay.

The reciprocity HMRC applies: a deductible premium means a taxable payout

Suppose a policy does clear all the conditions and the company has been deducting the premiums. When the claim is paid, HMRC's position is that the proceeds are a trading receipt of the company, taxable as income in the year they are received. This is the reciprocity in action, and it is stated in the same guidance that sets out the deduction.

It follows that a company relying on key person cover to replace lost profits should expect the payout to be taxed if it took the deduction. The lump sum that arrives is not the amount the company keeps. Corporation tax takes a slice first, and only the remainder is available to do the job the policy was bought for. A business that insured for the exact shortfall it expected to face will find that the tax has eaten into the very margin it was trying to protect.

What tax does to the sum the company really needs: grossing up

This is where the reciprocity stops being an accounting curiosity and starts costing real money. If the proceeds are taxable, the sum assured has to be set higher than the bare figure the business needs, so that what is left after tax still meets the need. Working out that higher figure is called grossing up, and it is a routine calculation a broker or accountant should do as a matter of course — but only if they have spotted that the payout will be taxed in the first place.

How big the uplift needs to be depends on the rate of corporation tax the company pays, which in turn depends on its level of profits.

The main rate of Corporation Tax is 25 per cent, with a lower small profits rate of 19 per cent for companies with smaller profits and marginal relief in between; which applies depends on the company's profits for the period.

The practical consequence is simply this: on a policy whose proceeds are taxable, a company that decides it needs a given net sum to survive the loss must insure for meaningfully more than that, so the figure surviving corporation tax still clears the gap. Get that wrong and the cover is quietly under-sized from the day it starts. Get it right and the after-tax proceeds match the need. It is not a difficult calculation, but it only happens if someone knows the payout is taxable — which is exactly the fact the cheerful version of this topic leaves out.

When the premiums are not deductible, and the payout is not taxed

The other side of the line deserves its own moment, because for many businesses it is where their policy actually sits, and it is not a bad place to be. Where the premiums are not deductible — because the insured person is an owner, or the cover is really for a loan or a shareholding — the proceeds are not normally treated as a taxable trading receipt.

For cover protecting borrowing or a share purchase, that is often exactly what you want. You forgo tax relief on relatively modest premiums, and in exchange the whole payout arrives without a tax charge, so the sum assured and the sum received are the same and no grossing up is needed. That can be the cleaner outcome, particularly where the amount has to match a specific debt or a fixed buy-out price. The right structure depends on what the cover is for, and it interacts with the arrangements that govern a share purchase on death — which is why cover for buying out an owner is usually planned together with the legal side rather than in isolation. Where inheritance tax on business assets is the concern rather than the company's own protection, that is a different policy again, of the kind we describe in life cover written in trust to meet a business inheritance tax bill.

Get it confirmed before you rely on the number

The single most useful thing to take from all this is that you cannot tell, from the outside, which side of the line a given policy falls on. It depends on the insured person's stake, the purpose of the cover, the type of policy and the facts of the case. That is a question for an accountant who knows the business, and it is worth settling before the cover is arranged, not after a claim, when it is too late to change the sum assured.

Two further points are worth holding in mind. First, cover has to be put in place while the person is healthy and insurable; leaving it until the key person is already unwell is a different and much harder conversation, as we set out in arranging key person cover when the key person is already ill. Second, the tax treatment of the payout to the company is a separate question from how any personal cover is taxed in the family's hands, where trusts do much of the work — a topic we cover in why a personal life payout can be taxed and how a trust prevents it.

If you want the cover priced and structured correctly for what it is actually for, you can get life insurance quotes and have an FCA-authorised broker work with your accountant on the deductibility and the grossing up. Our guide to what happens to a business when the owner dies puts this alongside the other decisions a business owner faces.

Scotland and Northern Ireland

There is no regional twist to this one. Corporation tax and the income tax rules that govern the deductibility of premiums and the taxation of proceeds are set at UK level and are not devolved, so the reciprocity in BIM45525 and the grossing-up point apply identically to a company in Edinburgh, Belfast, Cardiff or Manchester. The corporation tax rate that determines the size of the uplift is the same across the UK. What can differ, as always, is the succession and estate machinery around the people involved — but the tax treatment of the key person policy itself does not change with the border.

Frequently asked questions

Is key man insurance tax deductible in the UK?

Sometimes. HMRC guidance allows a deduction where the policy is short-term term assurance, relates only to loss of profits caused by the employee's death, and the person insured has no substantial stake in the business. Many owner-manager policies fail at least one of those conditions, most often because the insured person is also an owner, so the premiums on a great deal of small-company cover are not in fact deductible.

If we get the deduction, is the payout taxed?

Yes, and that is the trade-off. Where the premiums have been allowed as a business expense, the proceeds are generally treated as a taxable trading receipt of the company. Claiming relief on the way in usually means paying tax on the way out, which is why a policy whose payout will be taxed often has to be grossed up so the after-tax sum still meets the need.

What if the premiums are not deductible?

Then the proceeds are not normally treated as a trading receipt either, so the payout arrives without a tax charge. That can suit a business protecting a loan or a shareholding rather than its profits, where you want the full sum assured to arrive intact. The point is to know which side of the line the policy sits on before you rely on the figure, and to confirm it with an accountant.
