Keyman Insurance for International Businesses: A Complete Guide

Introduction

For any business that depends on the skills, relationships, or specialist knowledge of one or a small number of individuals, the unexpected death or serious illness of that person is not merely a personal tragedy — it is a financial event with the potential to threaten the viability of the business itself. Lost revenues, broken client relationships, disrupted operations, and the cost of finding and training a replacement can impose costs that are difficult or impossible to absorb without advance planning.

Keyman insurance — also referred to as key person insurance — is a straightforward instrument for managing this risk. This guide sets out how it works, how to size it correctly, how HMRC treats it for UK businesses, and how it applies to the types of international business structures commonly used by UK expats and internationally mobile business owners.

What Keyman Insurance Covers

Keyman insurance is a policy taken out by a business entity on the life of an individual whose loss would materially damage the business. The business is:

• The policyholder (it takes out and owns the policy)
• The premium payer (it meets the cost of the premiums)
• The beneficiary (it receives the payout)

The policy does not benefit the individual or their estate. It is a business asset, not a personal one.

Life cover pays a lump sum if the key person dies during the policy term. This is the most commonly arranged form of keyman cover and the most straightforward.

Critical illness cover pays a lump sum if the key person is diagnosed with one of the specified conditions covered by the policy — typically cancer, heart attack, stroke, and a range of other serious conditions. Critical illness cover is frequently added alongside or instead of life cover, particularly where the business risk arises from the individual's incapacity rather than only their death.

Many policies combine both elements — a joint life and critical illness policy that pays whichever occurs first.

Who Qualifies as a Key Person?

There is no single definition, but the key person test is a financial one: would the loss of this individual cause a quantifiable financial impact on the business? Common examples include:

• A founding director whose personal relationships underpin major client accounts
• A technical specialist whose knowledge or regulatory approvals cannot easily be replicated
• A lead sales professional responsible for a disproportionate share of revenue
• A director who has provided personal guarantees on business borrowing
• A creative professional, fund manager, or professional whose credentials attract clients or investment

The question is not whether the individual is important in an abstract sense, but whether their loss would produce a measurable financial loss to the business.

Calculating the Sum Assured

The sum assured on a keyman policy should reflect the financial exposure the business faces. There is no universally mandated method, but the following approaches are commonly used:

Revenue or profit multiple: Identify the revenue or gross profit attributable to the key person and multiply by the number of years needed to recover. A key person generating £300,000 in annual gross profit, with an estimated 3-year recovery period, would suggest a sum assured of approximately £900,000.

Salary multiple: A simpler approach uses a multiple of the key person's remuneration package — typically 5× to 10× gross salary, depending on the nature of the role and the business's recovery capacity. HMRC does not mandate a specific multiple.

Loan or debt coverage: Where the key person has provided a personal guarantee on a business loan or bank facility, the outstanding debt should be covered. Lenders will often require evidence of keyman cover as a condition of lending.

Shareholder value: Where the policy is intended to fund the repurchase of shares from a deceased director's estate, the sum assured should reflect the agreed or independently valued share value. This is distinct from pure keyman cover and edges into shareholder protection territory — the two policies are often arranged in conjunction.

Underwriters will generally require business accounts and an explanation of the methodology. For high sums assured (above £2 million is a common threshold), more detailed financial evidence may be requested.

UK Tax Treatment of Keyman Insurance

HMRC has published detailed guidance on the tax treatment of keyman policies in its Business Income Manual (principally BIM45525 and BIM45530). The position as of 2026 is as follows.

Premiums are deductible as a trading expense if:

• The sole purpose of the policy is income protection (i.e. compensating for lost profits or revenue), not capital protection
• The key person is an employee or director, not a proprietary director whose departure would affect the capital value of the business
• The policy is a short-term, annually renewable or fixed-term policy with no surrender value or investment element

Premiums are not deductible if:

• The policy is intended, wholly or partly, to fund the repurchase of shares or a capital transaction (this shifts the purpose to capital protection)
• The policy has an investment or endowment element
• The key person is a proprietary director (a director-shareholder whose personal goodwill constitutes a significant capital element of the business)

The payout, if premiums were deductible, is treated as taxable trading income in the year it is received. If premiums were not deductible, the payout is a capital receipt.

This distinction is important and not always straightforward in practice. A mixed-purpose policy — partly income, partly capital — may require apportionment. HMRC does not provide bright-line rules for all scenarios. Obtaining a written technical opinion on the deductibility position before policy inception is advisable for significant policies.

Offshore and International Business Structures

UK businesses are not the only ones with keyman needs. Many UK expats operate through international holding structures — Cyprus holding companies, UAE free zone entities, BVI companies, or Singapore-incorporated businesses. These structures may have directors or key shareholders resident in multiple countries.

International life assurance providers — including major Isle of Man and Guernsey-based companies — can issue keyman policies for non-UK companies. The key points for international business owners:

The company must be the policyholder and premium payer. The policy is a company asset. Corporate documentation confirming the company's entitlement to take out insurance on the key person's life is typically required at underwriting.

Tax deductibility depends on the company's jurisdiction. Cyprus has its own corporation tax rules (a flat rate of 15% from 1 January 2026, raised from 12.5% to meet the OECD global minimum, and still among the EU's lower rates) and its own guidance on the deductibility of insurance premiums. UAE free zone entities may have zero corporate tax on qualifying income under the UAE corporate tax introduced in June 2023. Tax advice from a local specialist is required — UK HMRC guidance does not apply to foreign companies.

Underwriting is on the individual's health, regardless of the company's structure. Medical questionnaires, medical examinations, and financial evidence of the business's need will be required. The process is the same as for personal cover.

Offshore policy providers operating in the Isle of Man and Guernsey are well-equipped to handle keyman policies for international companies, with experience of multi-jurisdiction structures and the ability to issue policies in currencies other than sterling (USD, EUR, and AED are commonly available).

The Process for Arranging Keyman Insurance

1. Identify the key person or persons. Be specific about which individuals the business cannot readily replace and over what timescale.
2. Calculate the financial exposure. Use the revenue, profit, or loan-coverage approaches above, and document the methodology.
3. Determine the cover required. Life only, critical illness only, or both. Fixed term (usually 5 to 20 years) or to a specified age. Currency of the sum assured.
4. Obtain indicative terms. Your adviser will approach the market — or, for international companies, offshore providers — for indicative premiums based on the key person's age, health, and the sum assured.
5. Complete the application and underwriting. The key person completes the personal and medical questionnaire. Medical evidence is obtained where required.
6. Confirm the tax position. If the company intends to claim a deduction for premiums, seek a written confirmation from your tax adviser before policy inception.
7. Keep the policy and business records aligned. As the key person's role, remuneration, or the business's financial position changes, review the sum assured at regular intervals.
