Private medical insurance through your Limited Company
Understanding the tax implications
Private medical insurance can be an attractive perk for directors and employees alike. Faster access to treatment, reduced waiting times and peace of mind are all valuable benefits, especially for business owners where time away from work can have a direct impact on the company.
However, one of the most misunderstood areas is how the tax works when private medical insurance is paid for by a limited company.
In particular, many business owners ask:
- Why is it taxable?
- How is the Benefit in Kind (BIK) calculated?
- Who actually pays the tax?
Let’s break it down in plain English.
What Is a Benefit in Kind (BIK)?
A Benefit in Kind is a non-cash benefit provided by a company to an employee or director. HMRC treats many of these benefits as part of your overall remuneration package, even though you are not receiving extra salary.
Private medical insurance falls into this category because the company is paying for something that personally benefits the individual.
In HMRC’s eyes, this is effectively additional income.
Why Is Private Medical Insurance Taxable?
If a company paid you an additional £1,000 salary, you would pay Income Tax on it.
HMRC therefore applies similar principles when the company pays £1,000 towards a personal benefit such as private healthcare.
Even though you do not physically receive the cash, you still receive a personal benefit with a financial value attached to it. That is why it becomes taxable as a Benefit in Kind.
How Is the Benefit in Kind Calculated?
The calculation itself is actually fairly straightforward.
The taxable Benefit in Kind is usually based on:
The total annual insurance premium paid by the company.
This includes:
-
- The director or employee’s cover
- Partner or family cover included on the policy
- Any additional medical benefits included within the package
For example:
| Annual premium paid by Company | Tax Band | Personal Tax Cost |
| £500 | 20% taxpayer | £100 |
| £1,000 | 40% taxpayer | £400 |
| £1,500 | 45% taxpayer | £675 |
The company-paid premium is added to the employee or director’s taxable income, and tax is charged at their marginal tax rate.
Who Pays the Tax?
This is where confusion often arises.
The Employee or Director
The individual receiving the benefit pays the Income Tax.
Usually, HMRC collects this by adjusting the person’s PAYE tax code, meaning the tax is spread across the tax year through payroll.
So while the company pays the insurance premium itself, the individual pays tax on the value of the benefit.
The Limited Company
The company also has a tax cost.
In most cases, the company must pay:
-
- Class 1A National Insurance Contributions (NIC)
- Currently charged at 15% on the value of the benefit
So if the company pays a £1,000 annual premium:
-
- The employee/director may pay £200–£450 in Income Tax depending on their tax band
- The company may also pay £150 in Class 1A NICs
Does the Company Get Corporation Tax Relief?
Usually, yes.
Private medical insurance is generally treated as an allowable business expense for Corporation Tax purposes, provided it is wholly and exclusively for the purposes of the business remuneration package.
This means the company can usually claim Corporation Tax relief on:
- The insurance premium
- Employer’s Class 1A NIC
So although there is a Benefit in Kind charge, there is still often an overall tax-efficient outcome compared to paying additional salary.
How Is It Reported to HMRC?
Traditionally, Benefits in Kind are reported on a P11D form after the end of the tax year.
The company must:
-
- Submit P11Ds for affected employees/directors
- File a P11D(b)
- Pay Class 1A NIC to HMRC
Some employers now “payroll” benefits instead, meaning the tax is collected in real-time through payroll rather than via tax code adjustments. This is coming in to effect for all employers from April 2027 so watch this space!
Is private medical insurance worth it?
For many directors and business owners, the answer is still yes.
Although there is a tax charge, the actual personal tax cost is usually significantly lower than the cost of purchasing equivalent cover personally from post-tax income.
For example:
- A £1,200 company-paid policy may only create a personal tax cost of:
- £240 for a basic rate taxpayer
- £480 for a higher rate taxpayer
The company still receives Corporation Tax relief on the premium, making it a commonly used and valuable director benefit.
Key things to remember
-
- Private medical insurance paid by a company is usually a taxable Benefit in Kind
- The taxable value is normally the annual premium paid by the company
- The employee/director pays Income Tax on the benefit
- The company pays Class 1A National Insurance
- The company can usually claim Corporation Tax relief on the cost
- The benefit must normally be reported to HMRC via P11D or payroll benefits
