Private Medical Insurance as a Benefit in Kind 2026/27: Complete Guide
Employer-paid private medical insurance is one of the most common employee benefits — and one of the most commonly misunderstood for tax purposes. This guide explains exactly how the benefit-in-kind charge is calculated, how it is reported through a P11D or payrolled through PAYE, and the narrow exemptions that apply to health screenings and overseas treatment.

Key Facts
Taxable value:Cost to employer of providing cover
Employee NI on the benefit:None
Employer charge:Class 1A National Insurance
P11D deadline:6 July following the tax year
Why It Is Taxable
HMRC treats employer-funded private medical insurance as a benefit in kind because it is something of monetary value provided to the employee outside their normal salary. Unlike some benefits that are specifically exempted (such as employer pension contributions or certain workplace nursery provision), general private medical insurance has no blanket exemption, so its value is added to the employee's taxable income for the year, typically without any employee National Insurance, but with employer Class 1A National Insurance.
Calculating the Taxable Value
For a standard commercial group policy, the taxable value is simply the premium the employer pays for that employee's cover (including any family members insured under the same policy). This figure is usually provided directly by the insurer or broker as part of the annual policy renewal documentation, making it straightforward for payroll or the P11D preparer to apply.
Where an employer operates a self-insured scheme rather than buying commercial cover, the calculation is more complex and is based on an appropriate proportion of the actual cost of providing the benefit, which may need actuarial input to determine fairly.
Reporting: P11D vs Payrolling
Employers have two ways to report and collect tax on this benefit. The traditional route is to include the premium value on each employee's P11D after the tax year ends, and HMRC then usually amends the employee's tax code for the following year to collect the tax gradually through PAYE — meaning there is often a delay between receiving the benefit and paying the tax on it.
Alternatively, an employer that has registered with HMRC to payroll benefits can add the taxable value of the medical insurance to the employee's pay each period and deduct tax in real time through PAYE. This removes the need for a P11D for that specific benefit and means the tax is collected in the same year the benefit is provided, which many employees find easier to understand.
Salary Sacrifice Restriction
Private medical insurance sits on the list of benefits excluded from the favourable tax treatment normally available under salary sacrifice arrangements (known as Optional Remuneration Arrangements). Where an employee gives up salary in exchange for PMI, they are taxed on whichever is higher: the amount of salary sacrificed, or the normal benefit-in-kind value of the insurance. In practice this usually means there is no tax saving from structuring medical insurance through salary sacrifice, unlike benefits such as pension contributions or ultra-low emission company cars, which remain outside this restriction.
Exemptions
One health screening assessment and one medical check-up per employee per tax year, if offered generally to staff
Emergency or necessary medical treatment (or insurance covering it) needed while the employee is working outside the UK
Treatment for injuries, illnesses or disabilities caused by the employee's work, in certain limited circumstances (recommended by a healthcare professional as part of a return-to-work plan, subject to a monetary cap)
These exemptions are narrowly defined. A general private medical insurance policy providing ongoing cover for the employee's health does not fall within any of them and remains fully taxable.
Worked Example
An employer pays a £900 annual premium for an employee's private medical insurance, which also covers the employee's partner, bringing the total premium to £1,400. The full £1,400 is the taxable benefit value for that employee.
A basic-rate taxpayer pays 20% income tax on this benefit — £280 — either via a tax code adjustment (P11D route) or through payroll if the employer payrolls benefits. The employer separately pays Class 1A National Insurance on the £1,400 value. The employee pays no National Insurance on the benefit itself.
Common Pitfalls
Forgetting dependants' cover increases the value. The taxable benefit includes cover for a spouse or children insured on the same policy, not just the employee's own portion.
Assuming salary sacrifice saves tax on PMI. It normally does not, because private medical insurance is excluded from the beneficial salary sacrifice rules.
Missing the P11D or payrolling registration deadline. Employers must register to payroll a benefit before the start of the tax year it applies to — it cannot be added retrospectively partway through the year.
Frequently Asked Questions
Is employer-paid private medical insurance taxable?
Yes. When an employer pays for, or contributes to, an employee's private medical insurance (PMI) policy, it is treated as a taxable benefit in kind. The employee pays income tax on the value of the benefit, and the employer pays Class 1A National Insurance on it, unless a specific exemption applies (such as insurance covering treatment needed solely because of work duties abroad, or certain health screening and check-ups).
How is the taxable value of private medical insurance calculated?
The taxable value is normally the cost to the employer of providing the cover — typically the premium the employer pays to the insurer for that employee (and any dependants covered), not a value estimated by the employee. If the employer runs a self-insured or partially self-insured scheme rather than buying a standard commercial policy, the taxable value is based on the appropriate proportion of the cost of providing the benefit, which can be more complex to calculate.
How is the tax on private medical insurance actually collected?
There are two main methods. Under the traditional method, the employer reports the benefit on a form P11D after the end of the tax year, and HMRC adjusts the employee's tax code to collect the tax, usually the following year. Alternatively, if the employer has registered to payroll benefits, the taxable value of the medical insurance is added to the employee's pay each period and taxed through PAYE in real time, removing the need for a P11D for that benefit and avoiding the tax code adjustment.

Does the employee pay National Insurance on private medical insurance?
No, employees do not pay Class 1 National Insurance on the value of employer-paid private medical insurance, because it is a benefit in kind rather than cash earnings. However, the employer pays Class 1A National Insurance on the value of the benefit, currently at the same main rate that applies to employer secondary Class 1 contributions, which increases the true cost of providing the benefit to the business.
Can private medical insurance be provided through salary sacrifice?
Private medical insurance is one of the benefits excluded from the beneficial tax and National Insurance treatment normally available under salary sacrifice (Optional Remuneration Arrangement) rules, alongside company cars (except ultra-low emission vehicles), accommodation and school fees. This means that even if provided via a salary sacrifice arrangement, PMI is taxed on the higher of the salary given up and the normal benefit-in-kind value — so there is no tax advantage in sacrificing salary specifically to fund private medical insurance.
Are annual health screenings or check-ups taxed the same way as full medical insurance?
No. HMRC allows an exemption for one health screening assessment and one medical check-up per employee per tax year, provided these are made available to employees generally (not selectively) and meet the specific conditions in the exemption. A full private medical insurance policy providing ongoing treatment cover is a different, taxable benefit and does not fall within this narrow screening exemption.
Is medical insurance provided while working abroad always taxable?
There is a specific exemption for medical treatment or insurance provided to an employee (and, in some cases, accompanying family members) where the need for treatment arises while the employee is working outside the UK, to cover emergency or necessary treatment abroad. General UK private medical insurance provided to employees who happen to travel for work does not automatically qualify for this narrower overseas treatment exemption — the conditions are specific and should be checked carefully.
Does the value of medical insurance for a spouse or family member also count as a benefit?
Yes. If the employer-paid policy also covers the employee's spouse, partner or children, the cost of that extended cover is also a taxable benefit in kind for the employee, added to the value reported on the P11D or payrolled through PAYE. Employers typically receive a single combined premium figure per employee, which already reflects the cost of any dependants covered under the policy.
What is a P11D and when is it needed for medical insurance?
A P11D is the form employers use to report the cash equivalent value of benefits in kind, including private medical insurance, provided to each employee during the tax year, where those benefits have not already been payrolled. It must normally be submitted to HMRC by 6 July following the end of the tax year, with a copy given to the employee, and any Class 1A National Insurance due on the P11D benefits must be paid by 19 July (or 22 July if paying electronically).
Is it worth having employer-paid private medical insurance despite the tax charge?
For most employees, yes, because the benefit-in-kind tax charge is normally significantly lower than the cost of buying an equivalent policy personally, since employer group schemes typically get better rates than individual policies and there is no need to gross up for the fact that private purchases are made from after-tax income. Whether it makes sense for a particular individual depends on their marginal tax rate, whether they value the specific cover offered, and whether they already have adequate NHS or other provision.
