As an FCA-authorised broker that has helped arrange over 800,000 policies, we at WeCovr know that understanding private medical insurance (PMI) in the UK goes beyond just the cover. A key question for employees is how company-paid health insurance affects their taxes. This guide demystifies the P11D rules for you.
If your employer provides you with private medical insurance, it's a fantastic perk that offers peace of mind and faster access to treatment. However, because it has a monetary value, HM Revenue & Customs (HMRC) considers it a 'benefit-in-kind'. This means it's treated as part of your overall earnings and is subject to income tax.
The process involves your employer calculating the value of the benefit, reporting it to HMRC on a P11D form, and you paying the corresponding tax. Don't worry, it's a standard process, and we'll break it down step-by-step.
Think of a P11D form as an annual report your employer sends to HMRC. It details the cash equivalent of any benefits and expenses they've provided to you on top of your salary. This isn't just for health insurance; it can include company cars, interest-free loans, and other perks.
Why does it matter to you?
Your employer must provide you with a copy of your P11D form by 6th July each year, following the end of the tax year on 5th April.
A "benefit-in-kind" is anything of value provided by your employer that isn't included in your salary. Because private health cover has a clear cash value—the premium your employer pays—it falls squarely into this category.
The value of the benefit is simply the total cost of the insurance premium your employer paid for you during the tax year. For example, if your company's policy costs £60 per month for your cover, the annual benefit-in-kind value is £720.
Key Points to Remember:
Before we delve deeper into the tax implications, it's crucial to understand what standard UK private medical insurance covers. This knowledge is essential for managing your health and financial expectations.
PMI is designed for ACUTE conditions. An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include joint replacements, cataract surgery, or treatment for hernias.
Standard PMI policies DO NOT cover:
While PMI is invaluable for getting prompt treatment for new, eligible conditions, you will still rely on the NHS for the management of chronic and pre-existing issues.
Calculating the tax you'll owe is straightforward once you know the value of the benefit and your income tax rate.
The Formula:
(Annual Cost of PMI Premium) x (Your Highest Income Tax Rate) = Total Tax Due for the Year
Let's look at some real-life examples.
Example 1: Sarah, a Basic Rate Taxpayer
Calculation:
HMRC will adjust Sarah's tax code to collect this £168 over the following tax year, meaning she'll pay an extra £14 per month in tax.
Example 2: David, a Higher Rate Taxpayer
Calculation:
David will see his take-home pay reduced by £36 per month to cover this tax.
Here’s a table summarising the tax impact at different levels:
| Annual PMI Premium Cost | Annual Tax Due (Basic Rate 20%) | Annual Tax Due (Higher Rate 40%) | Annual Tax Due (Additional Rate 45%) |
|---|---|---|---|
| £600 | £120 | £240 | £270 |
| £900 | £180 | £360 | £405 |
| £1,200 | £240 | £480 | £540 |
| £1,800 | £360 | £720 | £810 |
Note: Tax rates and bands are based on 2024/2025 figures for England, Wales, and Northern Ireland. Scottish income tax rates differ.
For most employees, the process is largely automated, but it's good to know what's happening behind the scenes.
If you complete a Self-Assessment tax return, you must also declare the benefit-in-kind value from your P11D in the relevant section.
This is a common point of confusion. Here’s the simple breakdown:
Using our example of David, whose PMI premium cost £1,080 for the year:
This means the total cost to the employer for providing this benefit is £1,080 (premium) + £149.04 (NICs) = £1,229.04. This is an important factor for businesses when they decide to offer private medical insurance UK wide.
Some company schemes require employees to pay a portion of the premium, or you might choose to upgrade your cover at your own expense. This is known as "making good".
If you contribute towards the cost, the taxable benefit is reduced by the amount you pay.
Example: Maria's Contributory Scheme
Calculation:
By contributing, Maria has reduced her annual tax bill on the benefit from £480 (£1,200 x 40%) down to £336, saving her £144 in tax.
Many employers allow you to add your partner or children to your company PMI policy. This is a fantastic and often cost-effective way to get private health cover for your whole family. However, it's vital to understand the tax rules.
Scenario Comparison:
| Scenario | Employee Covered | Partner Covered | Children Covered | Total Annual Premium | Taxable Benefit for Employee |
|---|---|---|---|---|---|
| Employer Pays All | Yes (Paid by employer) | Yes (Paid by employer) | Yes (Paid by employer) | £2,500 | £2,500 |
| Employee Pays for Family | Yes (Paid by employer) | Yes (Paid by employee) | Yes (Paid by employee) | £2,500 | £900 (Employee's portion) |
| Employee & Employer Split (Employer pays 50% of total) | Yes (50% employer paid) | Yes (50% employer paid) | Yes (50% employer paid) | £2,500 | £1,250 |
Choosing the best PMI provider and understanding the costs for family members is complex. An expert broker like WeCovr can compare the market for you, presenting clear options and explaining the full cost, including the tax implications, at no extra cost to you.
Employers are increasingly offering a wider range of wellness perks. Their tax treatment can vary, which is useful to know.
| Benefit Type | Taxable? | P11D Reporting? | Notes |
|---|---|---|---|
| Private Medical Insurance (PMI) | Yes | Yes | The core topic of this guide. |
| Dental Insurance | Yes | Yes | Treated identically to PMI as a benefit-in-kind. |
| Annual Health Screening | No (if one per employee, per year) | No | HMRC provides a specific exemption for one health screening and one medical check-up per employee annually. |
| Eye Tests for VDU Users | No | No | If you are required to use a screen for work, your employer can provide eye tests tax-free. |
| Employee Assistance Programme (EAP) | No | No | Generally considered a tax-free welfare benefit. |
| Gym Membership | Yes (unless provided in-house and available to all staff) | Yes | A paid-for membership at a public gym is a taxable benefit. An on-site gym for all staff is usually exempt. |
| Wellness Apps (like CalorieHero) | No (Generally) | No | Usually considered a trivial benefit with no P11D implications, especially when provided as a complimentary extra with another service. |
