For any small business owner, your team is your greatest asset. Keeping them healthy, happy, and productive is paramount. This is where Private Medical Insurance (PMI) comes in, offering a powerful tool to support your employees' wellbeing and minimise disruption from illness.
But when it comes to the cost, a crucial question arises: "Is business health insurance tax-deductible?"
The short answer is yes, usually. The premiums your business pays for employee health insurance are generally considered an allowable business expense. However, the full story is more nuanced, with different rules for your employees and for you as a business owner.
This comprehensive guide will walk you through everything you need to know, in plain English, about the tax implications of private medical insurance for small businesses in the UK.
Before we dive into the taxes, let's clarify what we're talking about. Business PMI, also known as a group health insurance scheme, is a policy taken out by a company to provide private healthcare access for its employees.
Its primary purpose is to cover the costs of diagnosis and treatment for acute conditions that arise after you take out the policy.
Crucial Point: Standard private medical insurance in the UK does not cover pre-existing conditions (illnesses you already had before the policy started) or chronic conditions (long-term illnesses like diabetes or asthma that require ongoing management rather than a cure). PMI is for new, curable health issues.
The key benefits for your business and team include:
Now, let's connect these benefits to your balance sheet.
Yes, for a limited company, the cost of the PMI premiums you pay for your employees is considered a legitimate business operating cost, just like salaries or rent. This means you can deduct the full cost from your company's revenue before calculating your Corporation Tax bill.
| Expense Type | Tax Deductible? |
|---|---|
| Employee Salaries | Yes |
| Office Rent | Yes |
| Utility Bills | Yes |
| Employee PMI Premiums | Yes |
This deduction reduces your taxable profit, which in turn lowers the amount of Corporation Tax you have to pay. With the main rate of Corporation Tax at 25% (as of 2024/25), this can represent a significant saving.
However, there's a catch. While the business gets a tax break, the provision of health insurance is treated as a 'Benefit in Kind' for the employee. This has tax implications for them and National Insurance implications for you.
Let's break this down based on your business structure.
This is the most common structure for small businesses offering PMI. The process involves three key areas: Corporation Tax for the business, Income Tax for the employee, and National Insurance for the business.
As mentioned, the entire premium cost is an allowable business expense.
Because the employee is receiving a non-cash benefit from their employment, HMRC treats it as additional income.
Because you are providing this benefit, the business must also pay Employer's National Insurance on the value of that benefit.
Let's make this real. Imagine 'Innovate Ltd.', a small tech company with 5 employees. The company decides to offer a PMI policy to its team.
Here’s how the numbers stack up for the business:
| Item | Calculation | Cost / (Saving) |
|---|---|---|
| Initial Premium Cost | 5 employees x £800 | £4,000 |
| Corporation Tax Saving | £4,000 x 25% | (£1,000) |
| Class 1A NICs Cost | £4,000 x 13.8% | £552 |
| Net Cost to Business | £4,000 - £1,000 + £552 | £3,552 |
Conclusion for the Business: The actual cost to Innovate Ltd. is £3,552 for the year, not the initial £4,000. This is a net saving of £448.
And for one of the employees:
| Item | Calculation | Cost |
|---|---|---|
| Value of Benefit | The premium cost | £800 |
| Income Tax Due | £800 x 20% | £160 per year |
Conclusion for the Employee: The employee gets access to private healthcare worth £800 for an annual tax cost of £160 (or about £13.33 per month deducted from their salary).
The rules are different if you are a sole trader or part of a partnership. The key distinction is how the cost of cover for the business owners themselves is treated.
| Person Covered | Premium Deductible? | Tax Implications |
|---|---|---|
| Employees | Yes | The premium is a business expense. However, it's a Benefit in Kind for the employee, who pays income tax on it. The business also pays Class 1A NICs. |
| Sole Trader (You) | No | You cannot claim the premium for your own private health cover as a business expense. It must be paid for out of your post-tax income. |
| Partners in a Partnership | No | Similar to a sole trader, the cost of PMI for the partners themselves is not an allowable business expense. It's considered a personal cost. |
Why the difference? HMRC's logic is that for a sole trader or partner, medical treatment is for the benefit of the individual person, not wholly and exclusively for the business. While your health is vital to your business, the benefit is not seen as purely a business one.
For your employees, however, the rules are the same as for a limited company. You can deduct their premiums as a business expense, but you must also report it as a Benefit in Kind on a P11D form and pay the associated Class 1A National Insurance.
The P11D is a form employers must submit to HMRC for each employee who has received expenses or benefits in addition to their salary. It can seem daunting, but it's a standard part of UK payroll.
If you use payroll software, it can often help you manage and submit P11D information. If you're unsure, your accountant will be your best friend here.
While PMI itself is a taxable benefit, HMRC does allow some specific health and welfare benefits to be provided tax-free. As a business owner, you can offer these without creating a P11D liability for you or a tax bill for your employee.
These include:
Many modern business health insurance plans now include access to services like an EAP or a 24/7 virtual GP service. Sometimes, the cost of these elements can be separated, potentially reducing the taxable BIK value. An expert broker, like WeCovr, can help you understand the structure of different policies.
Seeing that the employee has to pay tax on their benefit might make you pause. Is it still worth it? For most businesses, the answer is a resounding yes. The return on investment (ROI) goes far beyond the tax calculations.
Consider the cost of sickness absence. According to the Office for National Statistics (ONS), an estimated 185.6 million working days were lost because of sickness or injury in the UK in 2022, the highest level in a decade.
Let's revisit 'Innovate Ltd.':
The value of having that employee back at full capacity, contributing to projects and generating revenue, will almost certainly outweigh the £160 in tax they paid for the benefit. It's a classic case of a 'win-win'. You get a productive, valued employee, and they get fast, high-quality medical care.
Once you've decided to proceed, the next step is choosing a policy. The private medical insurance UK market is vast, with options to suit every budget and business size.
