For HMRC, the first question about a health cash plan is whether your employer provides it. HMRC's guidance on medical or dental treatment and insurance tells employers what to report and pay, and the answer turns on who arranges the cover, who pays the provider and whether an exemption fits. That guidance is written for employers, so for a plan you buy yourself, HMRC or an accountant can tell you where you stand. Weighing a plan offered at work against one in your own name? An FCA-authorised broker can explain how each would be set up and who would hold the policy; a free call-back is one submission of the form on this page away.
What follows is general information, not tax advice; for your own position, HMRC, your payroll department or an accountant is the place to settle it.
Health cash plan tax: the questions HMRC asks of an employer
HMRC's Employment Income Manual sets the starting rule. EIM21774 (updated 14 February 2023) says that what an employer spends on an employee's medical treatment "is generally chargeable to income tax", either as earnings or as a taxable benefit.
That leaves an employer three things to settle:
- Does an exemption fit? If one does, there is nothing to report and no tax or National Insurance to pay on that benefit, though salary sacrifice changes this. The exemptions, each with its conditions, come further down.
- Who arranges it, and who pays the provider? Each answer leads to a different route.
- What is it worth? That value is what gets reported or put through payroll.
Whose name the contract is in can decide the route, so ask for the plan's paperwork before assuming either way.
When a health cash plan from work is taxable: the guide's three routes
For treatment or insurance that is not exempt, HMRC's employer guide on GOV.UK, "Expenses and benefits: medical or dental treatment and insurance" (last updated 27 May 2015 and still current when read on 21 October 2026), gives three routes, quoted in the right-hand column. The National Insurance split matches HMRC's National Insurance Manual table NIM13150 (updated 8 February 2023): Class 1A where the employer contracts for the treatment or insurance, Class 1 where the employee does.
| How it is arranged | What the guide says the employer must do |
|---|---|
| The employer arranges the cover and pays the provider directly | "report it on form P11D" and "pay Class 1A National Insurance on the value of the benefit" |
| The employee arranges it, but the employer pays the provider | "report it on form P11D" and "add the value of the benefit to the employee’s earnings when deducting and paying Class 1 National Insurance (but not PAYE tax) through payroll" |
| The employer reimburses the employee's costs | "This counts as earnings, so:" "add the payments to your employee’s other earnings" and "deduct and pay PAYE tax and Class 1 National Insurance through payroll" |
Source: HMRC, GOV.UK, "Expenses and benefits: medical or dental treatment and insurance", section "What to report and pay".
The guide then adds a line that matters to anyone given money towards health costs rather than a plan: "The same rules apply whether you provide your employee with a cash allowance or additional salary to meet medical costs."
HMRC's Employment Income Manual looks at the insurance route from the employee's side. EIM21762 (updated 30 December 2015) makes a director or employee chargeable where "the employer, or somebody acting on behalf of the employer, contributes to a medical insurance scheme such as those operated by BUPA and PPP" and the employee, or members of their family or household, are covered by the policy. The charge is on the premium paid for them and their family or household, less any part of it they make good. Whether a particular cash plan counts as a medical insurance scheme in that sense is a question about the plan, best put to HMRC or an accountant with the policy in hand.
Class 1A National Insurance and the value of the benefit
Class 1A belongs to the first route, where the employer arranges and pays the provider, and it is the employer's charge rather than a deduction from your pay. On the second and third routes the guide puts Class 1 National Insurance through payroll instead, with PAYE tax added on the third. How the P11D and Class 1A work for private medical insurance in particular is covered in our page on private health insurance and tax.
On value, the guide's rule is short: "The value to use is the cost to you of providing the treatment or insurance." Where the employer reimburses the employee, the value is the amount reimbursed. Where one premium covers a group, EIM21763 (updated 22 February 2022) says the amount for each employee or category of employee will usually be clear from the policy terms, and where exceptionally it is not, any reasonable method the employer adopts and the employees generally accept can be used. Under salary sacrifice, the guide has the employer report the salary given up instead, where that is more than the cost of the treatment or insurance.
Exemptions HMRC lists, and the conditions on each
The Employment Income Manual sets out the exemptions, each with its conditions, and they are narrow. Those nearest to what a cash plan pays for:
- Health screening and check-ups. EIM21765 (updated 7 April 2026) limits the exemption to one health-screening assessment and one medical check-up per tax year; check-ups for an employee's family or household are a chargeable benefit unless that person is also an employee of the same employer, and medical checks connected to the provision of medical treatment fall outside the exemption.
- Eye tests and glasses for screen work. EIM21765 also exempts an eyesight test required under health and safety regulations for an employee who uses a screen as part of their normal duties, and glasses or contact lenses needed solely for that use where the test shows them to be necessary, provided these are available generally to all employees. From 6 April 2026 the exemption extends to the employer paying or reimbursing those costs, on the same conditions.
- Flu vaccinations. HMRC's employer guide lists these as exempt whether the employer provides them or reimburses the cost.
- Treatment to help an employee return to work. EIM21774 (updated 14 February 2023) says: "The exemption applies to expenditure up to a cap of £500 per tax year per employee." Before the treatment is recommended, the employee must have been assessed by a health care professional as unfit (or expected to be unfit) for work because of injury or ill health for at least 28 consecutive days, or have been absent from work because of injury or ill health for at least 28 consecutive days. The recommendation must come from a health care professional as part of occupational health services, be made to help the employee back to work, be in writing, go to both employer and employee, and name the treatment. Costs above the cap are taxed in the normal way.
Two narrower exemptions sit alongside these. Under EIM21766 (updated 2 October 2015), treatment outside the UK carries no charge where the need for it arises while the employee is abroad to carry out their duties; insurance for that treatment is covered too, but family members are not. Under EIM21770 (updated 12 December 2018), an employer's policy that insures an employee only against injury or illness at work, with no family or household members on it, is not a taxable benefit; one that also covers injury outside work is. Salary sacrifice cuts across all of these: "You do have to report your employees’ medical or dental treatment or insurance if they are a part of a salary sacrifice arrangement." EIM21774 likewise says the return-to-work exemption does not apply to treatment provided under salary sacrifice.
Whether any benefit on a given plan falls inside one of these exemptions turns on the plan's terms read against each condition; what health cash plans pay and cost goes through the usual benefits.
A cash plan you pay for yourself, and what it pays out
HMRC's guidance on medical benefits covers what employers provide. For a plan you pay for yourself, and for the money such a plan pays back to you, ask HMRC or an accountant how it applies to you.
Either will want the set-up, which you can pin down first:
- Whose name is the plan in, yours or your employer's?
- Who pays the provider, and is anything taken from your pay towards it? Under EIM21762, a share of the premium you make good reduces the charge.
- When you claim, does the plan pay you, or does your employer reimburse you? Reimbursement is the third route in the table above.
- Is any of it arranged through salary sacrifice?
If the plan is a Bupa one, our page on Bupa health cash plans covers the product itself, and for medical insurance rather than a cash plan, putting a number on an employer-paid Bupa benefit and which private health insurance is cheapest for tax take the question further. Torn between a cash plan and medical cover bought privately? An FCA-authorised broker can ring to explain how either would be set up, once you have asked for a call with the form on this page.
Cash plan tax questions, answered briefly
Is a health cash plan a taxable benefit?
From an employer, it can be: unless an exemption fits, it has to be reported, and tax or National Insurance may follow depending on the route in the table above. For a plan you fund yourself, HMRC or an accountant can confirm the position.
Is a health cash plan a benefit in kind?
Not on every route. In the guide, cover the employer pays the provider for, whoever arranges it, goes on form P11D, whereas costs the employer pays back to you count as earnings through payroll. Your payroll department can tell you which applies to your plan.
Is a cash plan taxed differently from private medical insurance?
HMRC's guide deals with medical or dental treatment and insurance under one set of routes rather than separate rules for each. Whether a specific cash plan counts as treatment or insurance for that purpose is something HMRC or an accountant can confirm.
Is a cash plan payout taxable?
Ask an accountant or HMRC, who can look at how your own plan is set up and paid for before saying how its payouts are treated.
