Private health insurance and tax: P11D and benefit in kind — what it costs

Private health insurance meets the tax system in two places. If an employer pays for your cover, HMRC treats the premium as part of your pay and taxes you on it, which surprises people who had filed the scheme under "free perk". If you pay for your own, there is no relief to claim, and the only tax in the picture is the one already built into the premium. Which applies to you turns on who pays the insurer.

The decision underneath the search is usually one of three: join a company scheme you have been offered, buy cover yourself instead, or put a policy through a business you own. The tax is one input and the price is the other, and the price is a quote: an FCA-authorised broker can put current quotes from several insurers beside the scheme you have been offered, or price a policy in your own name. Fill in the form on this page to be put in touch with one; it is free and takes a few minutes.

Said once, because it applies to everything below: this page sets out the general UK position as we understand it. It is not tax advice, we hold no HMRC guidance behind it, and the figures that matter to you — your marginal rate, what your employer actually paid, what your tax code has been adjusted by — are for HMRC, your payroll department or an accountant to settle. What it can do is lay the rules out plainly enough that you know which questions to ask.

Who pays the insurer decides how it is taxed

Three arrangements, three treatments.

Your employer pays. The premium is a benefit in kind. HMRC counts it as though you had been paid the money, and you pay income tax on it. You do not pay National Insurance on it; your employer pays a separate employer's charge on the value, called Class 1A, which is its cost rather than yours.

You pay. A policy bought with your own money comes out of income that has already been taxed, and nothing comes back: no deduction, no allowance, no credit, whether you are employed, retired or self-employed. The premium you are quoted already includes Insurance Premium Tax.

A company you own pays. The company can normally treat the premium as a business expense, but you, as a director and employee, are taxed on it as a benefit in kind like any other employee, and the company pays the employer's charge on top.

Sole traders have no employer to provide a benefit, and a premium for their own cover is personal rather than a cost of the trade, so it is not set against profits.

P11D private medical insurance: the cost to you

The P11D is the form on which an employer reports to HMRC, after the end of each tax year, the benefits it gave each employee that were not taxed through the payroll; private medical insurance is one of the standard entries, and you get a copy. The figure against medical insurance is the "cash equivalent" of the benefit: what it cost your employer to provide it, which for insurance means the premium paid for you, less anything you paid towards it. Three things follow.

It is the premium, not the treatment. The value you are taxed on is what the employer paid the insurer, and it has nothing to do with whether you claimed: a year of no treatment and a year with an operation in it carry the same benefit. Nor are you taxed on the cost of treatment the insurer paid for.

It includes anyone else on your cover. If your employer pays for a partner or children on your policy, their premium is part of your benefit. If you pay for them yourself by a deduction from your net pay, that contribution reduces the benefit, because you have made good part of the cost.

It is taxed at your rate, not taken in full. The cash equivalent is added to your other income and taxed at whatever rate applies to the top slice of it, so what the cover costs you in tax is a share of the premium set by your marginal rate: basic rate for a basic-rate taxpayer, higher rate for a higher-rate taxpayer, the Scottish bands for a Scottish taxpayer. HMRC's income tax pages give the current rates. Paying tax on a premium is not the same as paying the premium, which is why a scheme is rarely worth refusing on tax grounds alone.

How the tax is collected depends on your employer. On the P11D route, HMRC receives the figure after the year end and adjusts your tax code so that the tax comes out of your pay over the following year; a company scheme therefore shows up as a smaller personal allowance on your coding notice rather than as a line on your payslip. On the payrolling route, the employer puts the value through the payroll each pay day, the tax comes out as you go, and nothing appears on a P11D. HMRC has announced that payrolling is to become the standard route for most benefits, though the timetable has changed once already; if you are unsure which applies to you, ask payroll.

A benefit in kind also counts towards the income figure HMRC uses for the personal allowance taper and the High Income Child Benefit Charge, so a premium paid on your behalf can carry you across a threshold your salary alone would not. Your payslip will not warn you; an accountant will.

The two sums in a policy, and which one the tax touches

A policy puts two different sums in front of you. The first is the premium, paid to the insurer whether or not you are ever ill. The second is what you pay at the point of treatment: the excess, any co-payment, and any bill above a benefit limit. Everything above attaches to the first sum only. The second is your own money: not a benefit from your employer, so it is not taxed; not a premium, so it attracts no relief and carries no Insurance Premium Tax. That matters because the dials that lower the first sum raise the second, and on a company scheme it is the employer who sets the dials.

The clauses below are from individual policies, which are what we hold. A group scheme runs on the employer's wording, which we have not read; these show the shape of the dials, not the terms of your scheme.

The excess

Aviva's terms put the first dial in one sentence:

"Benefits covered under this policy will be subject to an excess payable for each member every policy year."

— Aviva, Healthier Solutions terms and conditions (April 2025 issue), page 11, read 4 September 2026.

The same page lists six levels, from £100 to £5,000. The premium falls as the level rises — the shape of the market, not a figure — so on an employer-paid scheme a higher excess means a lower premium and a lower taxable benefit, in exchange for more of each claim coming from your pocket. "For each member" means that on a family policy each person carries their own.

Bupa's policy guide shows where that money goes:

"Helen has some physiotherapy which costs £250. We pay Helen's physiotherapist £150 and we'll let Helen know that she needs to pay the physiotherapist £100 (which is the policy excess). If Helen needs other treatment during the policy year, she doesn't need to pay another excess."

— Bupa, Bupa By You policy guide (BINS 14718, 2024), page 10, read 4 September 2026.

Helen's £100 goes to the physiotherapist, from her own money, and nothing about it passes through an employer or HMRC; if her cover were employer-paid she would be taxed on the premium exactly as before. Freedom's guide has the same mechanism from the insurer's side: the excess is deducted "from the first valid invoice we receive and from any subsequent valid invoices until the excess has been fully applied", after which "you will then need to pay the excess amount to the relevant provider" (Freedom Health Insurance, Freedom Elite Policyholder's Guide to Cover, April 2025, page 31, read 4 September 2026). On both wordings the money is settled with the clinic and never touches your tax position.

Not every use of a policy starts the excess, either:

"If you have a Direct Access phone or video assessment you won't need to pay an excess for it and the cost won't be subtracted from your outpatient benefit allowance (if either of these apply to your policy)."

— Bupa, Bupa By You policy guide (BINS 14718, 2024), page 7, read 4 September 2026.

What you pay yourself in a year therefore varies with how you use the policy; the taxable value does not move at all.

A co-payment

WPA's product summary offers a second way of sharing the cost, alongside the excess:

"Where an excess is chosen, you must pay your excess for eligible treatment up to your chosen level per Policy year before we provide benefit. Where Shared Responsibility (co-payment) has been selected, you must pay 25% of claims for eligible treatment up to your chosen level of Shared Responsibility."

— WPA, Complete Health Insurance Product Information Document (November 2025), page 2, read 4 September 2026.

A quarter of every eligible bill, from the first pound, until your contributions reach a ceiling you chose; it is the only percentage co-payment in the documents we hold, and we have not established whether other insurers offer one. For tax it behaves like the excess: a lower premium, so a lower benefit if an employer pays, and a share of each bill that is yours alone.

Out-patient limits

The third dial caps what the insurer pays for a category of treatment. WPA's summary shows a cap and the option that lifts it:

"Out-patient Treatment Consultations with a Specialist – £250 (increase with the Extra Out-patient Consultations Optional Extra)"

— WPA, Complete Health Insurance Product Information Document (November 2025), page 1, read 4 September 2026.

Once the cap is used, the rest of that year's consultations are yours to pay, and the extra that raises it raises the premium. Aviva's wording shows that a reduced limit can take cover away in places you would not expect:

"If you have chosen a reduced out-patient limit of £500 or £1,000 you are not covered as an in-patient, day-patient, or out-patient for treatment for: complications of pregnancy and childbirth, or surgical procedures on the teeth performed in a hospital"

— Aviva, Healthier Solutions terms and conditions (April 2025 issue), page 8, read 4 September 2026.

A cheaper structure is cheaper because it covers less, and on an employer scheme the thing removed is removed from you, while the tax you save on the lower premium is a fraction of a fraction. To weigh a scheme against a policy of your own, you need the scheme's benefit table alongside the same cover priced in your own name at the same excess and limits. A broker can ask several insurers for the second half of that in one conversation; the form on this page puts you in touch with one.

Buying your own cover: no relief, and Insurance Premium Tax inside the price

"How much tax benefit on health insurance" is a search that mostly arrives from outside the UK. In India, section 80D of the Income-tax Act gives a deduction for health insurance premiums; in the United States, premiums for an employer plan usually come out of pay before tax. Nothing of the kind exists here. A UK resident buying their own cover pays from taxed income and gets no deduction, no allowance and no credit.

The tax that is in the picture is Insurance Premium Tax: a tax on general insurance premiums, charged to the insurer and passed on in the price, which private medical insurance pays at the standard rate. At the time of writing the standard rate is 12%, and it has not changed for several years, 2024 included; a Budget can change it, so treat the rate HMRC publishes as the one that counts. It is already inside any premium you are quoted. It is not VAT, so a business paying a premium cannot reclaim it. And it is charged whoever pays, so the figure on your P11D is the premium with the tax in it.

Cover through your own limited company

The general shape when a company you own buys the policy: the company pays the premium and can normally deduct it in working out its taxable profit, as it would any staff cost. You, as a director on the payroll, receive a benefit in kind of the same amount and pay income tax on it at your marginal rate, and the company pays the employer's National Insurance charge on it. Whether that beats drawing the money out and buying the cover yourself depends on the company's tax position, your own, and the rates in the year in question, which is why it is an accountant's question.

One thing to check: that the policy is in the company's name, with the company contracting with the insurer. If the policy is in your own name and the company simply pays the premium for you, HMRC treats the payment differently for National Insurance; that applies to any employee whose employer pays a personal policy, not only to directors.

Taking a company scheme, or turning it down

If you have been offered cover at work, the tax is usually the smaller consideration; the cover is what tends to decide it. The employer chose the insurer, the excess, the out-patient limit and the hospital list, and a scheme with a reduced limit or a large excess may leave you paying more at the point of treatment than the words "company healthcare" led you to expect. Ask for the scheme's benefit table, and read it the way you would read any policy.

Three more things to settle. Whether you can add a partner or children, and who pays for them, since that changes your benefit. What happens when you leave, since the cover normally ends with the job and a policy you then buy yourself starts afresh unless the insurer offers to continue it individually; ask while you are still a member. And whether the scheme is offered in exchange for giving up salary or alongside a cash alternative: rules introduced in 2017 for optional remuneration arrangements tax you on the higher of the salary you give up and the cost of the cover, so salary sacrifice does not make medical insurance cheaper in tax terms.

Turning the scheme down, where the employer allows it, means no benefit, no tax and no cover; nobody in the UK is required to hold private health insurance.

Common questions

How much is benefit in kind tax on health insurance?

The premium your employer paid for your cover, less anything you contributed, taxed at your marginal rate of income tax. There is no separate "BIK rate" for medical insurance; it is ordinary income tax on an addition to your income, so the answer depends on which band the top of your income falls in. Your P11D or payslip gives the value, and HMRC's rates page gives the rate.

Are group health insurance premiums taxable?

Yes, in two places. The employee is taxed on their share of the premium as a benefit in kind, and the premium itself carries Insurance Premium Tax. For the employer, the premium is normally a deductible cost of employing staff, with employer's National Insurance due on the benefit.

How much tax benefit is there on health insurance?

None, for an individual in the UK. The phrase usually comes from India or the United States, where premiums can attract a deduction. A UK policy you buy yourself is paid from taxed income with no relief, and a policy an employer buys for you adds to your tax rather than reducing it.

Do teachers pay for health insurance?

Not as a condition of the job. The search mostly comes from the United States, where a school district's plan takes a contribution from pay; in the UK the NHS covers teachers like everyone else. A teacher who wants private cover buys it from taxed income with no relief, unless the school or trust provides it, in which case it is a taxable benefit like any other employer-paid cover; your contract or HR department will say.

How much is private health insurance per month for a teacher?

We hold no premium data, so we do not quote one. The price turns on age, where you live, the level of cover, the excess and the underwriting route, and a teacher is quoted on those like anyone else.

Is the excess I pay when I claim tax-deductible?

No. It is your own money, paid to the hospital or clinic, and it is neither a benefit nor a premium: it does not reduce your tax, and it is not taxed. On the wordings quoted above it is settled with the provider, not the insurer.

Is any employer-paid healthcare tax-free?

A few narrow things are, and insurance is not one of them. Our understanding is that an annual health screening, eye tests required for screen work, and treatment recommended by occupational health to get you back to work are exempt within limits HMRC sets; confirm any exemption with HMRC before relying on it.

If you now know which of the three arrangements you are in, the remaining question is the price, and that is a quote. Fill in the form on this page, and an FCA-authorised broker will put current quotes from several insurers in front of you, in your own name or through your company, with the excess and limits you have just read about priced at more than one level.
