Generally, yes. For limited companies, premiums are usually an allowable expense for corporation tax, so £1,000 of premiums costs around £862 net at the 25% main rate. Employees pay income tax on the premium as a benefit in kind, and the company pays Class 1A NIC at 15%. Sole traders can't deduct their own cover.
- ✓Ltd companies: premiums are generally an allowable corporation tax expense; sole traders' own cover isn't.
- ✓Employees pay BIK income tax: roughly £120/year on a £600 premium at basic rate, £240 at higher rate.
- ✓Employers pay Class 1A NIC at 15% of the premium — £90 on a £600 policy.
The short version: relief for the company, BIK for the employee
When a limited company pays for employees' private medical insurance, three taxes are in play. First, the premium is generally an allowable expense, reducing the company's corporation tax bill — because providing staff benefits is a legitimate cost of doing business ("wholly and exclusively" for the trade). Second, each covered employee is taxed on the premium as a benefit in kind (BIK). Third, the employer pays Class 1A National Insurance at 15% on the benefit's value.
The rules differ sharply by business structure, so let's take each in turn. Throughout, remember tax treatment depends on individual circumstances — confirm specifics with your accountant. One thing worth saying early: none of these charges usually makes company-paid cover a bad deal. For the employee, a modest benefit-in-kind bill buys cover that would cost far more to purchase individually; for the company, relief takes a meaningful slice off the gross cost.
Limited companies vs sole traders
Limited companies: premiums for employees — including directors on payroll — are generally deductible against corporation tax. The company claims the expense; the covered person is taxed on the BIK. This applies whether you cover two staff or two hundred.
Sole traders and partners: your own health insurance is treated as a personal expense, not a business one — HMRC's view is that keeping yourself healthy has an intrinsic personal benefit, so it fails the "wholly and exclusively" test. You can, however, generally deduct premiums for any employees you cover. If you're self-employed with no staff, see our self-employed health insurance guide for how personal cover is priced instead.
This structural difference is one reason some contractors and consultants incorporate: through a limited company, health cover becomes a deductible business cost (with the BIK trade-off below), whereas a sole trader pays the whole premium from taxed income. It's rarely a reason to incorporate on its own — but if you already run a limited company, paying for cover through it is usually more efficient than paying personally, once relief and BIK are netted off.
What employees pay: BIK worked examples
The taxable benefit is normally the premium the company pays for that employee (including any family members added). The employee then pays income tax on that amount at their marginal rate — currently collected via a tax code adjustment after P11D reporting, moving to real-time payrolling from April 2027.
| Annual premium paid by company | Basic-rate employee (20%) | Higher-rate employee (40%) |
|---|---|---|
| £600 | ≈£120/year (£10/month) | ≈£240/year (£20/month) |
| £900 | ≈£180/year (£15/month) | ≈£360/year (£30/month) |
| £1,320 (family cover) | ≈£264/year (£22/month) | ≈£528/year (£44/month) |
In other words, a typical employee gets private cover worth £600+ a year for the price of a couple of coffees a month in extra tax. That's why health insurance consistently ranks as the most-valued voluntary benefit.
How the tax is collected is changing. Today the employer reports each employee's premium on a P11D by 6 July after the tax year, and HMRC adjusts the employee's tax code — so the tax arrives with a lag, sometimes catching people out. From April 2027 the benefit moves onto the payslip in real time. Either way the employee should tell HMRC if their circumstances change mid-year (for example, coming off the scheme) so their code stays accurate.

What the company pays: Class 1A and the net cost
On top of premiums, the employer pays Class 1A National Insurance at 15% of the benefit value, reported annually on form P11D(b). On a £600 premium that's £90; on a £10,000 scheme it's £1,500. The good news: both the premiums and the Class 1A NIC are themselves generally deductible for corporation tax.
| Worked example (25% corporation tax) | Amount |
|---|---|
| Annual premiums | £1,000 |
| Class 1A NIC at 15% | +£150 |
| Gross cost | £1,150 |
| Corporation tax relief at 25% on £1,150 | −£287.50 |
| Net cost to the company | ≈£862 |
IPT, VAT and what's already in your quote
Health insurance premiums carry insurance premium tax (IPT) at 12%, not VAT — and it's already included in the premiums insurers quote. There's nothing extra to add on, and equally nothing to reclaim: IPT is not recoverable the way input VAT is, even for fully VAT-registered businesses.
Two related points trip businesses up. First, because IPT applies to premiums rather than VAT, health insurance doesn't appear anywhere on your VAT return — it's simply a cost. Second, when comparing a group scheme against giving staff cash to buy their own cover, remember the cash route suffers employee income tax and employee NIC and employer NIC as ordinary salary, while the benefit route swaps employee NIC for the flat 15% Class 1A charge — one reason the benefit is usually the more efficient structure.
From April 2027, HMRC plans to mandate payrolling of benefits in kind, moving medical insurance BIK from annual P11Ds into real-time payroll. The amounts of tax don't change — just when and how they're collected. Our payrolling benefits guide covers what employers need to do.

Frequently asked questions
Is health insurance tax deductible for sole traders?
Not for your own cover. HMRC treats a sole trader's or partner's personal health insurance as failing the "wholly and exclusively" business test, so it's paid from taxed income. Premiums for employees you cover are generally deductible. Limited company directors are employees, so their company can deduct — with BIK consequences.
Can my business reclaim VAT on health insurance premiums?
No — because there's no VAT on them. Premiums carry insurance premium tax (IPT) at 12% instead, which is included in quoted prices and is not recoverable. Unlike input VAT on goods and services, IPT can't be reclaimed by any business, however it's VAT-registered.
Does benefit-in-kind tax apply if an employee declines the cover?
Generally no. BIK arises when the benefit is made available to and taken up by the employee; someone who formally opts out of the scheme before cover starts has no premium paid for them, so nothing to tax. Get opt-outs in writing and remove the member from the insurer's list.
How is health insurance reported on a P11D?
Currently, the employer files a P11D for each covered employee after the tax year ends (deadline 6 July), showing the premium paid in the medical insurance box, plus a P11D(b) declaring the Class 1A NIC due. HMRC then adjusts employees' tax codes. From April 2027 this moves into real-time payroll for most benefits.
Does health insurance reduce corporation tax?
Generally, yes. Premiums for employee cover are typically an allowable expense, so a company paying 25% corporation tax saves £250 for every £1,000 of premiums; at the 19% small profits rate it saves £190. The Class 1A NIC on the benefit is also deductible. Loss-making companies get no immediate saving.
What is Class 1A National Insurance and who pays it?
Class 1A is employer-only National Insurance charged at 15% on the value of most benefits in kind, including medical insurance. Employees don't pay NIC on the benefit — only income tax. The company declares it annually on the P11D(b) and pays by 22 July following the tax year.
Is insurance premium tax added on top of my quote?
No. IPT at 12% is baked into the premium your insurer quotes, so the price you see is the price you pay. It's worth knowing it exists, though: when governments raise IPT, premiums rise across the market — it's one driver of renewal increases.
Does adding family members to an employee's cover increase their tax?
Yes. The taxable benefit is the total premium the company pays for that employee's membership, including any partner or children on their certificate. If family cover lifts the premium from £600 to £1,320, a higher-rate taxpayer's BIK bill roughly doubles from about £240 to about £528 a year.
If employees contribute towards the premium, does that reduce the benefit-in-kind?
Generally yes. Amounts an employee is contractually required to pay towards the cover ("making good") are deducted from the taxable value, provided they're paid within the deadline — for P11D benefits, by 6 July after the tax year. An employee covering the full premium themselves would typically have no BIK at all.
Is business health insurance a tax-efficient alternative to a pay rise?
Often, yes. A £600 premium costs a higher-rate employee about £240 in tax, but giving them £600 of extra gross salary would lose roughly £252 to income tax and NIC — and the company would pay 15% employer NIC either way. Plus the employee gets cover that costs more to buy individually.
