Is private health insurance a taxable benefit in kind?
If your employer pays for your private health insurance, HMRC treats it as a taxable benefit in kind (BIK). You pay income tax on the value of the cover — roughly the premium your employer pays — at your normal tax rate, and your employer pays Class 1A National Insurance on top. If you buy a policy yourself, there is no benefit in kind and nothing extra to pay. Here is how it works in the UK in 2026, what it costs you, and how it is reported.
The essentials in 30 seconds
- Employer-paid = taxable: private medical insurance provided by your employer is a benefit in kind, so you pay income tax on it.
- What you’re taxed on: the “cash equivalent” — broadly the cost to your employer of the cover (the premium) — taxed at your marginal rate (20%, 40% or 45%; Scottish rates differ).
- Employer National Insurance: your employer also pays Class 1A NI at 15% (2025–26 and 2026–27) on the same value.
- Bought it yourself? No benefit in kind and no extra tax — but individual premiums are not tax-deductible either.
- How it’s reported: via form P11D or through payroll now; real-time payrolling of medical benefits becomes mandatory from 6 April 2027.
Who pays what — at a glance
| Situation | Benefit in kind? | What you pay | What your employer pays |
|---|---|---|---|
| Employer pays your premium | Yes — taxable BIK | Income tax on the cash equivalent at your marginal rate (20% / 40% / 45%) | Class 1A NI at 15% on the same value |
| Employer offers it as salary sacrifice | Yes — taxed on the greater of the salary given up or the cash equivalent | Income tax on the taxable value | Class 1A NI at 15% on the taxable value |
| You buy your own policy | No | Nothing extra — you pay from taxed income; premiums are not deductible | Not applicable |
| Company director buying via the company | Usually yes — treated as a BIK on you personally | Income tax on the cash equivalent | Class 1A NI; the premium may be an allowable business expense for the company |
Indicative summary of the general UK tax treatment for the 2026 tax year, based on HMRC guidance (P11D / CWG5, Class 1A NI). Not tax advice and not a quote. Your own position depends on your income, tax code and how your employer runs the benefit — confirm with your employer, payroll or an accountant.
What it actually costs you
Say your employer pays a £600 a year premium for your cover. That £600 is the cash equivalent — the amount added to your taxable income. You do not pay the £600; you pay tax on it at your highest rate:
- Basic-rate (20%) taxpayer: £600 × 20% = £120 of tax for the year (about £10 a month).
- Higher-rate (40%) taxpayer: £600 × 40% = £240 for the year (about £20 a month).
- Additional-rate (45%) taxpayer: £600 × 45% = £270 for the year.
Separately, your employer pays Class 1A National Insurance of 15% on the £600 — that is £90 — but that is the employer’s cost, not yours. In practice the tax is usually collected by an adjustment to your tax code (if the benefit is reported on a P11D) or deducted through payroll each month if your employer payrolls the benefit. Figures here are illustrative and rounded; swap in your actual premium to gauge your own cost.

Why it’s taxed one way and not the other
A benefit in kind is something of value your employer gives you that is not cash pay — a company car, gym membership or, here, medical insurance. Because it saves you money you would otherwise spend from your own pocket, HMRC taxes it as if it were extra earnings. That is why employer-paid private medical insurance is caught: the company is buying you something worth having, so you are taxed on its value. It is reported to HMRC each year, most commonly on form P11D, or handled through payroll if your employer has registered to payroll the benefit.
When you buy your own policy there is no employer and no benefit in kind, so nothing is added to your taxable income — but you also get no tax relief, as private medical premiums are not deductible for individuals. That is one of several trade-offs between the two routes; company vs personal health insurance weighs them up in full, and the private health insurance hub links the rest of our PMI guides.
P11D now, payroll from April 2027
For the 2025–26 tax year, employers report medical insurance either on a P11D after the tax year ends (with the tax then collected through your code) or by payrolling the benefit, which spreads the tax across your monthly pay in real time. Either way, the employer pays Class 1A National Insurance — currently 15% — on the taxable value.
From 6 April 2027, payrolling most benefits in kind — including private medical insurance — becomes mandatory, so the P11D route for these benefits is being phased out. The change was originally planned for April 2026 but was put back a year to give employers and software providers time to prepare. It does not change whether the benefit is taxable — only how it is reported. If you are weighing up whether workplace or personal cover is right for you, is private health insurance worth it? works through the decision.
