Key Person Insurance Explained

Most businesses insure their premises, their stock and their vehicles without a second thought, yet leave uninsured the one asset they could least afford to lose: a person. Key person insurance fills that gap. It is a policy a company takes out on an individual whose death or serious illness would do real financial harm, the founder who holds the client relationships, the developer who wrote the software, the director whose name is on the bank facility. If the worst happens, the payout gives the business the cash and the time to survive the shock.

This guide explains what key person insurance actually covers, how to decide who to insure and for how much, the tax rules that catch out the unwary, and how it fits into a wider succession and exit plan. It is information rather than personal advice: the right structure depends on your company’s circumstances, and the tax treatment in particular rewards getting proper guidance before you buy.

What key person insurance is

Key person insurance, sometimes called key man insurance, is a policy owned and paid for by a business on the life, and often the health, of an individual central to its success. The company is the policyholder and the beneficiary: if the insured person dies, or in most modern policies suffers a specified critical illness, the insurer pays a lump sum directly to the business. That money is the company’s to use as it sees fit, to keep paying staff and suppliers, to recruit and train a replacement, to reassure a nervous bank, or simply to buy the time needed to steady the ship.

The distinction that matters is who benefits. Personal life cover pays a family; key person cover pays the company. It exists to protect the business itself against the operational and financial damage of losing someone irreplaceable, which is a very different risk from protecting a household or buying out a departing shareholder. That second risk, funding the purchase of a deceased owner’s shares, is dealt with by shareholder protection, a related but separate arrangement covered elsewhere in our business owners hub and easy to confuse with key person cover.

Who counts as a key person

A key person is anyone whose absence would materially hurt the company’s profits, cash flow or ability to function. In a small owner-managed firm that is very often the founder, who may embody the brand, hold the key relationships and personally guarantee the borrowing. But it is not only owners: a business can depend just as heavily on a star salesperson who brings in a large share of revenue, a technical specialist whose knowledge cannot easily be replaced, or a managing director whose leadership holds everything together.

• Owner-managers and founders whose relationships, reputation or guarantees underpin the business.
• Directors and senior managers responsible for strategy, leadership and lender confidence.
• Top sales or business-development people who personally generate a large slice of income.
• Technical experts, developers or designers whose specialist knowledge would be slow and costly to replace.
• Anyone named on, or relied upon for, key contracts, bank facilities or supplier relationships.

A useful test is to ask, bluntly, what would happen to next year’s profit if this person were gone tomorrow. If the honest answer is a serious dent in revenue, a threatened loan, or months of disruption while you scramble to replace them, that person is a candidate for cover. In practice most small companies identify one, two or three genuinely key individuals rather than a long list, and the exercise of naming them is valuable in its own right, because it forces owners to confront just how concentrated their business risk really is.

What it pays for

The payout is deliberately flexible, but it is bought to meet a handful of predictable pressures. The first is the straightforward loss of profit while the business absorbs the blow and rebuilds. The second is the cost of replacement, recruitment fees, a premium salary to attract a successor quickly, and the training and lead time before that person is fully productive. The third, often overlooked, is protecting borrowing: many lenders lend on the strength of a particular individual, and some loan agreements can even be called in if that person dies.

Cover is normally written to include critical illness as well as death, since a key person surviving a serious illness but unable to work leaves the business facing exactly the same gap. Policies are typically term assurance, cover for a set number of years matched to the period of risk, such as the term of a loan or the years until a planned succession, which keeps premiums proportionate rather than paying for whole-of-life cover the company does not need. It is worth distinguishing this from relevant life cover, which is a tax-efficient death-in-service benefit for an individual employee’s family; key person cover, by contrast, pays the business itself.

How much cover to take

There is no single right figure, but there are recognised ways to arrive at a defensible one. A common starting point is a multiple of the person’s contribution to gross profit, for example, twice or three times the profit reasonably attributable to them. Another is the cost to replace the individual, from recruitment through to the point of full productivity. A third simply sizes the cover on the specific borrowing or contracts that hinge on them. Whichever route you use, the aim is enough to keep the business trading and give it real breathing space, not to over-insure and waste premium.

The tax treatment

This is where key person insurance most often trips people up, because the tax on premiums and payout are linked. HMRC has never set the rules in statute; instead they flow from a 1944 parliamentary statement by the then Chancellor, Sir John Anderson, which is why advisers refer to the “Anderson rules”. In broad terms, premiums may be treated as a deductible trading expense only where three conditions are met: the insured is an employee rather than a substantial shareholder, the policy is intended solely to cover loss of profits (not a capital purpose such as repaying a loan or buying shares), and the term is short, usually meaning annual or short-term cover.

The catch is the mirror image: if the premiums are deducted, the payout is normally taxable as a trading receipt, whereas if the premiums are not deducted, the payout is usually received tax-free. So the tax “saving” on premiums can be clawed back many times over on a large payout. For cover on an owner who is also a significant shareholder, extremely common in small companies, premiums are typically not deductible, but the trade-off is that the lump sum is generally free of tax when it is needed most.

Because the position turns on the individual’s role and the policy’s purpose, this is not an area to guess at. It is worth reading alongside our wider personal tax planning guide and taking specific advice, ideally confirming the treatment with the insurer and, where the sums are large, with HMRC. Getting the structure right at outset avoids a nasty surprise at the very moment the business can least absorb one, and it ensures the payout does exactly the job you bought it for rather than being partly swallowed by an unexpected tax charge.

Fitting it into an exit plan

Key person cover is one piece of a broader resilience and succession plan, and it works best alongside the others. It sits naturally next to shareholder protection, which funds the purchase of a deceased owner’s shares, and behind both should be up-to-date wills, cross-option agreements and a clear plan for who steps in. For an owner thinking years ahead to a sale, keeping the business insurable and less dependent on any single individual also makes it more valuable and easier to sell, a theme we develop in our guide to selling your business. A buyer pays more, and diligence runs more smoothly, when the company is not perilously reliant on one irreplaceable person.

It also pays to look at the personal side in parallel. The same owners whose lives are insured for the business usually have families and estates of their own, and a serious illness or death has consequences well beyond the balance sheet, which is why reviewing personal protection, wills and inheritance tax planning at the same time is sensible. Vetted Wealth is a free concierge service that matches business owners with independently vetted, FCA-regulated advisers who arrange protection alongside genuine exit and succession planning, including specialists across Devon and Cornwall. This is information rather than personal advice, and the right cover and structure will always depend on your own circumstances.
