MTD IT Series: Insurance Premiums: What Types Are Allowable?

Step 1: Apply the Wholly and Exclusively Test

Every insurance claim is governed by one rule. The expense must be incurred wholly and exclusively for trade purposes for sole traders and companies.

HMRC focuses on purpose, not payment method. The question is simple. Would this cost exist if the business did not operate? If the answer is yes, the expense is not allowable.

A common example is life insurance for a sole trader. It exists regardless of trade activity. Even if paid through a business account, it remains personal.

Mixed-use policies are where most errors occur. Home insurance cannot be claimed in full if a property is used partly for business. Only the business portion is relevant, and that split must be set early and applied consistently.

Vehicle insurance follows the same logic.Where private and business use overlap, only the business element is considered for tax purposes.

Income protection and sickness cover are also problematic for sole traders. These policies usually protect personal income rather than trading profit. They only become relevant in narrow cases, such as locum arrangements under HMRC guidance.

Step 2: Insurance That HMRC Normally Accepts

Some insurance costs are clearly linked to trade activity and are normally allowable. Public liability insurance is fully allowable. It exists purely to cover third-party claims arising from business operations.

Employers’ liability insurance is also allowable and required by law where staff are employed. Its legal requirement reinforces its treatment as a business cost.

Professional indemnity insurance is another common category. It covers negligence claims from clients or third parties and is generally allowable. Classification varies across firms, but consistency is more important than label choice.

Business premises and contents insurance can also be claimed for trading assets. For home offices, only the business portion should be included based on a reasonable apportionment method.

Business interruption insurance is allowable where it protects trading income lost due to insured events. One point often missed is that any payout received later becomes taxable trading income.

Trade credit insurance is also allowable where it protects against customer default.

Locum insurance applies in specific professional fields such as medical and dental practices. Where it protects the continuity of the trade during absence, HMRC accepts it.

Step 3: Insurance That Is Not Allowable

Some policies fail regardless of structure or payment method. For sole traders, personal health, accident, sickness, and life insurance are not allowable. HMRC treats these as private expenditure. Paying through a business account does not change this position.

Key person insurance for sole traders and partnerships is also specifically disallowed. Even if the policy is held in the business name, it cannot be claimed.

Limited companies are treated differently, but only under strict conditions. Key person insurance may be allowable if all requirements are met. The payout must be revenue-based, the insured must be a director or employee, and the policy must not include any investment or endowment element.

If any condition is not met, the deduction is not allowed. Capital protection insurance is not allowable because it relates to capital loss rather than trading activity. HMRC investigation insurance is also not deductible under current guidance.

The principle remains consistent. Insurance must relate to trade risk, not personal or capital protection.

Step 4: Recording Insurance in MTD IT Updates

Most insurance expenses sit under other allowable business expenses in SA103F. Professional indemnity may also be classified under legal and professional fees, provided the same treatment is applied consistently across all quarters.

Consistency is critical. Changing categories between quarterly updates causes year-end mismatches.

Non-allowable insurance must not be entered as a disallowable adjustment. It should be excluded completely from submissions. Including it creates reconciliation issues later in the return.

From 2024/25, the cash basis is the default for many sole traders. Under this method, insurance is deductible in the quarter it is paid, so an annual premium is claimed in full when paid rather than spread over the policy term.

Under accrual accounting, prepayments must be split across the relevant periods. The approach should remain consistent unless a formal change is made.

Step 5: Pre-Submission Review

Before each quarterly update, review every insurance policy against the wholly and exclusively rule.

For sole traders, personal policies such as life, health, and sickness cover should be removed from expense listings. For companies, key person insurance should only be included if all HMRC conditions are satisfied.

Mixed-use insurance requires an agreed apportionment method. That method should be set at the start of the year and applied consistently across all quarters.

Annual insurance premiums should be set up as recurring entries in the accounting system to reduce classification errors.

Final Thought

Insurance is not difficult because the rules are complex. It is difficult because similar-looking policies are treated differently depending on structure and purpose.

Getting this right at the point of entry prevents later corrections and avoids issues during final submission review.
