Do You Pay Tax on Private Health Insurance from Work?

Yes, you pay tax on it. If your employer provides private health insurance, HMRC treats it as a benefit-in-kind (BIK) — essentially extra pay that happens to come as a perk instead of cash. You owe income tax on the value of the policy, and your employer owes Class 1A National Insurance on it too.

Most employees don't notice because the tax is collected through their tax code rather than as a separate bill. But it's worth understanding how it works, because the amount varies and there are ways to reduce the hit.

How the tax is calculated

The taxable amount is whatever your employer pays for your health insurance policy. Not the theoretical market value — the actual premium.

Say your employer pays £600 a year for your cover:

Tax band	Tax rate	Tax you pay on the benefit
Basic rate	20%	£120/year (£10/month)
Higher rate	40%	£240/year (£20/month)
Additional rate	45%	£270/year (£22.50/month)

If your policy also covers your partner or children, the full premium is taxable — not just the portion that covers you.

How HMRC collects the tax

In most cases, your employer reports the benefit on a P11D form (submitted to HMRC by 6 July each year). HMRC then adjusts your tax code to collect the extra tax. You'll see this on your coding notice as something like "medical insurance £600."

Some employers handle it through payrolling benefits instead, which means the tax is deducted directly from your monthly pay. Either way, the amount of tax is the same.

Your employer also pays 15% Class 1A National Insurance on the benefit value — that's their cost, not yours.

Check your tax code

Your tax code should reflect the benefit. Look for a reduction in your tax-free amount that roughly matches the insurance premium. If the number looks wrong (or if you've left a job that provided health insurance and the old benefit is still in your code), contact HMRC to get it corrected. Otherwise you'll overpay.

Family cover costs more in tax

This catches people out. If your employer's scheme covers your spouse and children, the entire premium is taxed as your benefit. A family policy might cost £1,500–£2,000 a year, which means a higher-rate taxpayer could pay £600–£800 extra in tax annually.

Ask your employer (or HR) what the actual premium is for your level of cover. Some people opt for individual-only cover through work and arrange separate policies for family members if it works out cheaper overall.

Salary sacrifice and health insurance

Some employers offer health insurance through a salary sacrifice arrangement. You give up a portion of your gross salary equal to the premium cost, and the employer pays for the insurance from that amount.

Here's the catch: since April 2017, most salary sacrifice arrangements for benefits-in-kind are taxed the same way as direct provision. Health insurance isn't one of the exempted benefits (pensions, childcare, cycle-to-work, and ultra-low emission cars are). So salary sacrifice won't save you tax on health insurance specifically, though it might save on National Insurance in some cases — check with your payroll team.

Employer-paid tax ("grossing up")

Some employers choose to pay the tax on your behalf. This is called grossing up. It's generous, but it creates a slightly odd loop: HMRC treats the employer's tax payment as another benefit, which itself is taxable. In practice, your employer handles the calculation, and you don't have to find the cash yourself.

Check your contract or ask HR whether your employer grosses up health insurance tax. It's more common at senior levels or in companies that really want the benefit to feel free to employees.

When health insurance isn't taxable

There are a few narrow exceptions:

• Medical treatment to help you return to work — if you're off sick and your employer pays for treatment (up to £500 per year) to get you back, this can be tax-exempt under certain conditions
• Health screening and eye tests — routine workplace health checks and DSE eye tests are exempt
• Overseas assignments — health cover for employees working abroad temporarily may be partially or fully exempt, depending on the tax treaty and the specifics

These are limited cases. For the vast majority of employees with standard workplace private health insurance, the benefit is taxable.

Is it still worth having?

Almost always, yes. Even at the higher rate, the tax on a £600 policy is £240 a year — £20 a month. Try buying equivalent private health insurance as an individual and you'd pay the full £600+ yourself, with no tax relief at all. Employer-provided cover is still significantly cheaper than going it alone, even after tax.

The real question is whether you need it. If you do, getting it through work is the most cost-effective way.
