Every year, around
this time, we get a flurry of calls from business owners who have just realised they have a P11D to deal with. Sometimes they have no idea what one is. Sometimes they know roughly what it is but have no idea the deadline is approaching, or that company directors should be included on it.
If you are an employer or a company director and you provided benefits to employees or yourself during the 2025/26 tax year, read on. The 6 July 2026 deadline is less than a month away, and the cost of getting it wrong is not just a fine – it is also Class 1A National Insurance at 15% on benefits you may not even have flagged as taxable.
What is a P11D form?
A P11D is the form employers use to report taxable benefits in kind to HMRC – things provided to employees (or directors) on top of salary that have a monetary value but were not processed through payroll. A separate P11D is required for each individual who received benefits. You also need to submit a P11D(b), which is the summary form that tells HMRC how much Class 1A National Insurance you owe across the whole company.
Benefits in kind are broader than most employers expect. They include things like company cars, private medical insurance, gym memberships, interest-free loans and non-trivial gifts. If your business provided any of these, to employees or to yourself as a director, those benefits almost certainly need to be reported.
The key P11D deadlines
6 July 2026: submit your P11D and P11D(b) forms to HMRC and give each employee their copy.
22 July 2026: pay any Class 1A National Insurance owed (19 July if paying by cheque).
Missing the filing deadline triggers automatic penalties. HMRC charges £100 per 50 employees for every month or part month the P11D(b) is late. That might sound modest for a small business, but interest and further penalties accumulate quickly – and HMRC has no obligation to prompt you.
What you must report: the common benefits in kind
The following are all reportable on a P11D if they were not payrolled during the year:
- Company cars and fuel – one of the most common benefits, calculated using HMRC’s CO2-based percentage scale
- Private medical or dental insurance – the full employer cost is taxable
- Gym memberships – taxable in full if the gym is not on employer premises
- Mobile phones – only one phone per employee is tax-free; a second handset is a taxable benefit
- Non-trivial gifts and vouchers – cash vouchers, gift vouchers and non-branded gifts above £50 per person per year are all taxable (see below)
- Interest-free or beneficial loans above £10,000
- Private use of a company van beyond the business-only exemption
What does NOT need to go on a P11D
Some benefits are exempt and should not appear on your P11D at all:
- Trivial benefits under £50 – provided they are not cash, not a reward for work performance, and not contractual. HMRC allows these without any reporting or tax, but each individual gift or benefit must be under the £50 limit
- The Cycle to Work scheme – provided through a salary sacrifice arrangement, this is generally exempt
- One mobile phone per employee
- Employer pension contributions
- Staff parties costing up to £150 per head per year (across all events combined)
- Use of a gym that is on the employer’s own premises and available to all staff
the gift voucher problem
A construction company director based in Dartford gave each of his employees a £100 Selfridges voucher as a Christmas bonus. He assumed that because the gifts were not cash, they would be fine. They were not.
The vouchers failed the trivial benefits exemption on two counts:
First, at £100 each they were double the £50 limit – and where a benefit exceeds £50, the entire amount becomes taxable, not just the portion above the threshold.
Second, a Christmas bonus framed as a reward for the year’s work risks falling into the “recognition of services” category that HMRC specifically excludes from the exemption.
Small mistake, big impact
With 50 employees each receiving a £100 voucher, that was £5,000 of taxable benefits that had not been reported. The company had to file a P11D(b), pay Class 1A National Insurance at 15% on the full £5,000 – that is £750 – plus interest for late payment. Each employee also had to be notified so they could declare the benefit on their own tax return.
The trivial benefits rules have four conditions, all of which must be met:
- The benefit costs £50 or less (per gift, not in aggregate across the year);
- It is not cash or a cash voucher;
- It is not provided in recognition of services performed; and
- It is not contractual.
A non-cash gift voucher for a high-street retailer can qualify – but only if all four conditions are satisfied. The voucher type alone does not determine the outcome.
Directors, do not leave yourself off the P11D
This is one of the most common mistakes we see. Directors often focus entirely on their employees and forget that they are also employees of their own company. If the company paid for your private health insurance, gave you a company car, or provided any other taxable benefit during 2025/26, you need your own P11D.
If you are already thinking carefully about the most tax-efficient way to pay yourself, through a combination of salary, dividends and pension contributions, it is worth ensuring your benefits are equally well-planned.

Class 1A National Insurance: why the numbers matter
Employers pay Class 1A National Insurance on most taxable benefits in kind. For 2025/26, that rate is 15% – the same as the standard employer NI rate that increased in April 2025.
Take private medical insurance as a common example. If you provide cover worth £1,500 per year to five employees, the total benefit value is £7,500. Class 1A NI at 15% adds £1,125 to your bill, on top of the insurance premium itself. Many employers set up health schemes without fully accounting for this additional cost. The more benefits you provide, the more it adds up.

What is changing from April 2027?
If you have heard talk about P11D forms being abolished, the detail matters. Mandatory payrolling of benefits in kind was originally due to start in April 2026 but was delayed by twelve months following industry feedback. From 6 April 2027, most employers will be required to report and tax benefits in kind through payroll in real time, rather than via an annual P11D.
This means that for the 2025/26 tax year – the one with a filing deadline of 6 July 2026 – the traditional P11D process still applies in full. You cannot ignore it on the basis that it is being phased out. The phase-out comes later, and you still need to manage the current year correctly.
Some employers have already registered to payroll their benefits voluntarily for 2025/26 or 2026/27. If you fall into that category, you will not need to submit a P11D for the benefits you have payrolled – but a P11D(b) is still required to declare the Class 1A NI due.

Frequently asked questions
What benefits must be included on a P11D?
Any taxable benefit provided to an employee or director that was not processed through payroll must be reported on a P11D. Common examples include company cars, private health insurance, gym memberships, non-cash vouchers and beneficial loans above £10,000. The trivial benefits exemption covers individual gifts under £50 that are not cash or vouchers, not a performance reward, and not contractual – but this exemption does not extend to anything that can be exchanged for money.
Do I need to submit a P11D for myself as a company director?
Yes. Directors are employees of their own company for tax purposes. If the company provided you with any taxable benefits during the tax year – a company car, private medical insurance, or anything else that would be reportable for an employee – those benefits must appear on your own P11D. This is one of the most commonly overlooked aspects of the process for small limited company directors.
What is the Class 1A National Insurance rate on benefits in kind for 2025/26?
For 2025/26, employers pay Class 1A National Insurance at 15% on the taxable value of benefits in kind. This is the same rate as standard employer National Insurance contributions following the April 2025 increase. The payment is due by 22 July 2026 if paying electronically, or 19 July if paying by post.
Are all gift vouchers taxable?
Yes, if they can be exchanged for goods or cash. HMRC treats gift vouchers and cash vouchers as equivalent to cash, which means they fall outside the trivial benefits exemption regardless of their value. A £30 voucher for a high-street retailer is taxable in full. The only non-cash gifts that can fall within the trivial benefits exemption are physical items – typically branded merchandise – costing under £50, provided the other conditions of the exemption are met.
