Private health insurance goes on a UK tax return only when an employer pays for it: the taxable value of that benefit has its own box on the Employment page, unless your employer has already taxed it through payroll. A policy you fund from your own money has no box and attracts no relief, so there is nothing to enter. Deciding between a company scheme and a personal policy? An FCA-authorised broker will put a price on the personal option during a free call-back, arranged through the request form on this page. This is the general position HMRC and GOV.UK set out, not tax advice; what the benefit costs you in tax has its own page.

Employer-paid cover: a P11D today, payroll reporting from April 2027

GOV.UK’s Tax on company benefits guide (page dated 17 December 2014, read 21 October 2026) puts it plainly: “You usually pay tax on the cost of the insurance premiums if your employer pays for your medical insurance.” HMRC’s National Insurance Manual (NIM13150, updated 8 February 2023) lists medical, dental treatment or insurance that the employer contracts for as carrying no Class 1 liability and a Class 1A liability. So there is no employee National Insurance on the policy when it is in the employer’s name, and the employer pays Class 1A.

For now the value reaches HMRC by one of two routes: on form P11D after the tax year ends, or through payrolling, where HMRC’s guidance (updated 6 April 2026) says: “You do not have to submit a form P11D for benefits and expenses that you payroll.” The employer still works out Class 1A and files form P11D(b). That guidance opens with the notice “The rules on reporting benefits and expenses are changing”, and tells employers: “You can only payroll benefits that you registered to payroll before 6 April 2026.”

What is due to change from 6 April 2027

HMRC’s interim guidance on mandatory payrolling of benefits in kind (last updated 23 September 2026) says real-time reporting will be phased in from 6 April 2027 for company cars, car fuel, vans, van fuel and “employer-provided medical benefits”, with most other benefits following from April 2028. Under that plan the medical benefit will be reported through payroll each pay day, and employers must send you a statement by 1 June after the tax year showing which benefits were payrolled and their value. HMRC expects that “most employers will no longer need to complete P11D or P11D(b) forms”, but the publication is interim: “Both the guidance and legislation may change before final versions are published from Autumn 2026 onwards.”

How the benefit shows in your tax code

GOV.UK’s Tax codes guide (dated 6 November 2024) lists “your employer tells HMRC you have started or stopped getting benefits from your job” among the reasons a code changes. Its illustration starts from the standard Personal Allowance of £12,570: “The medical insurance benefit of £1,570 is taken away from your Personal Allowance, leaving you with a tax-free amount of £11,000. This would mean your tax code is 1100L.” That is GOV.UK’s own example, not your code, and the guide attaches no tax year to it; £12,570 is also the standard Personal Allowance GOV.UK gives for the current tax year, 6 April 2026 to 5 April 2027. Once a benefit is payrolled, the code changes “to take out the adjustment for their benefits in kind” and the tax comes through pay instead.

You can see the company benefits HMRC holds in the Check your Income Tax online service. The company benefits guide adds that you must tell HMRC about benefits you or your family start or stop getting from work, “even if your employer has already taken Income Tax and National Insurance for them”.

Where private medical insurance goes on a UK tax return

If you file, the benefit belongs on the Employment page (SA102), which you complete “for each employment or directorship”. On the 2026 form, for the tax year 6 April 2025 to 5 April 2026 (print code HMRC 12/25), box 11 is “Private medical and dental insurance”, in the benefits section that tells you to use your P11D or equivalent information. HMRC’s Employment notes for that year (HMRC 12/25, page EN 3) say: “Put the figure from section I on your P11D in box 11.” The same page carries the exception: “If your employer has ‘payrolled’ your benefits and expenses (this means the tax was deducted from your pay and included in your P60) do not include them in boxes 9 to 20.”

A director whose company pays the premium uses the same box on that directorship’s page. If you repay a student or postgraduate loan and your benefits were payrolled, box 1.1 takes the payrolled benefits subject only to Class 1A, which the notes say include private medical and dental insurance.

Do you have to file a return at all?

A company benefit is not among the situations in GOV.UK’s Self Assessment guide that require a return, which name things such as sole trading above a set earnings level and being a business partner. The guide also says: “You must send a return if HMRC asks you to.” For the 2025 to 2026 tax year, GOV.UK’s “Check if you need to send a Self Assessment tax return” tool, HMRC or an accountant will settle it.

Cover you pay for yourself: nothing to enter, nothing to claim

The Employment page has no box for a premium you pay from your own money, and there is no relief to claim. HMRC’s Insurance Policyholder Taxation Manual (IPTM1200, updated 11 February 2016) records that relief on private medical insurance premiums existed for people over 60 only, between 1990 and 1997, was abolished for policies taken out or renewed after 1 July 1997, and is now “obsolete”.

That leaves the premium itself as the open question. Request the call-back and a broker can quote cover in your own name, to set against what a company scheme would cost you in tax.

Self-employed, partners and directors: what HMRC’s Business Income Manual says

Sole traders and partners. BIM37900 (updated 16 June 2026) says: “Some forms of expenditure by their very nature have an inevitable non-trade purpose and therefore are always disallowed.” Among the expenses the courts have held to carry that intrinsic duality of purpose, it lists “wishing to enjoy good health”. It also limits its own scope: “Note that the pages in this section of the manual purely relate to the expenses of the self-employed and those trading in partnership. This guidance does not relate to expenses incurred by companies.”

BIM45560 (updated 1 April 2016) says: “Premiums paid by a sole trader or partner to provide life, accident or sickness insurance cover for him/herself or a partner are not allowable deductions in computing trading profits. Such insurance policies are often known as permanent health insurance policies.” Neither page names private medical insurance, so how either applies to your premium is a question for your accountant.

Limited-company directors. For the company, BIM37007 (updated 1 April 2016) sets the test: “S34 Income Tax (Trading and Other Income) Act 2005 for unincorporated businesses and S54 Corporation Tax Act 2009 for companies prevent a taxpayer deducting expenditure in computing their trading profits unless it is incurred wholly and exclusively for the purposes of the trade, profession or vocation.” The director’s own tax is a separate matter: under the Employment Income Manual (EIM21762, updated 30 December 2015), the taxable amount is the premium paid to cover them and their family or household, minus any part they make good. There is more on director health insurance and health insurance for the self-employed.

Check-ups, eye tests and other health benefits HMRC does not tax

HMRC’s Employment Income Manual sets out a few exemptions, each with conditions:

  • Check-ups and screening. EIM21765 (updated 7 April 2026) exempts “no more than one health-screening assessment in any tax year” and “no more than one medical check-up in any tax year”. Checks connected to medical treatment fall outside it, and a check-up for a relative is taxed unless the relative works for the same employer.
  • Eye tests. The same page covers an eyesight test for an employee who must use a screen as part of normal duties, where Health and Safety at Work regulations require the test and it is available generally to all employees; from 6 April 2026 that includes the employer paying or reimbursing the cost.
  • Treatment to help you back to work. EIM21774 (updated 14 February 2023) exempts recommended treatment “up to a maximum cost of £500 in the tax year per employee”. Before the recommendation, a health care professional must have assessed you as unfit for work for at least 28 consecutive days, or you must have been off work that long, through injury or ill health; the recommendation must be made through occupational health services to help you return to work, in writing to both you and your employer, naming the treatment. The exemption “does not apply if the medical treatment is provided under salary sacrifice arrangements.”
  • Work-only cover. Under EIM21770 (updated 12 December 2018), a policy taken out “purely to cover an employee against work-related injury (and/or illness)”, with no family cover, carries no benefit charge; “If the insurance covers injury incurred both at work and outside work, a benefit will result.”

Would a personal policy include a health check of its own? What each plan actually offers is something the broker can lay out once they ring, free of charge.

Tax return questions, answered briefly

Does private health insurance affect my tax return?

Only cover your employer pays for. If you do not file, the tax comes through your tax code or, where the benefit is payrolled, your pay.

Is there a private health insurance offset or statement for a UK return?

Those are terms from other countries’ systems. A UK return takes its figure from section I of your P11D, not from an insurer; for payrolled benefits, your employer’s notice by 1 June after the tax year sets out what was taxed.

What if my P11D has not arrived?

The 2025–26 Employment notes say: “If you do not receive a copy of your P11D by 6 July 2026, contact your employer.” A benefit that was payrolled will not have one.

With the paperwork settled, what remains is price: a broker can quote a personal or company policy at no charge once you complete the request form on this page.
