P11D UK 2026/27 — Benefits in Kind, Tax Codes and Deadlines

A P11D is the form or statement used to report certain taxable benefits and expenses provided by an employer to an employee. It is relevant when your total reward is more than salary: for example, a company car, private medical insurance, an employer-provided loan or another benefit that is taxable under the UK rules. It helps HMRC calculate or reconcile Income Tax, and it helps you check whether the benefits shown on your tax record are reasonable.

The P11D is not the same as a P60, payslip or tax return. A P60 summarises pay and deductions through one PAYE employment or pension for the tax year. A payslip shows what payroll processed for a particular pay period. A P11D concentrates on reportable benefits and expenses. The employer also has a separate P11D(b) process for declaring the Class 1A National Insurance due on benefits. Employees do not complete the employer's P11D(b).

For 2026/27, the tax year runs from 6 April 2026 to 5 April 2027. An employer normally gives the employee the relevant benefits information by 6 July 2027, after the tax year ends. The exact treatment depends on the benefit, exemptions, payroll method and your employer's reporting. Use this guide to understand the document and the checks around it, not as a substitute for your own HMRC record or specialist advice.

What a P11D tells an employee

The useful question is not simply “Do I have a P11D?” but “Which benefits did my employer provide, how were they reported, and has the value been reflected correctly in my tax record?” A P11D normally identifies the benefit categories and the taxable value used for reporting. The amount is not necessarily cash paid to you. It may be the tax value of having private use of an asset, receiving insurance cover or accessing a loan on favourable terms.

If you have a company car, the P11D value can be affected by the car's list price, its CO2 emissions, the fuel benefit rules and private availability. The UK company car tax guide→ explains that calculation as its own decision. If the benefit is private medical insurance, read the employer's description and compare it with the UK private medical insurance tax guide. An employer-provided loan has different valuation and reporting questions, covered in the beneficial loan tax guide. A P11D is therefore a record to reconcile, not a universal benefit calculator.

The figure on a P11D can affect your PAYE tax code or a later HMRC calculation. That does not mean the figure itself is the tax you owe. The taxable benefit is generally added to your taxable income for Income Tax purposes, while the actual tax depends on your circumstances, tax bands, tax code and other income. National Insurance treatment is also not identical to employee Income Tax treatment: Class 1A is normally an employer liability on relevant benefits.

P11D, P11D(b), P60 and payslip: the difference

The documents can legitimately show different numbers because they answer different questions. A P60 is not supposed to reproduce every benefits-in-kind detail as a separate line. A payslip may show a payrolled benefit each month, whereas a separate P11D may show only benefits that were not payrolled. HMRC may use a benefit value to adjust a later tax code rather than collect all of the related tax in one payment.

This is why a simple comparison such as “P11D amount equals P60 pay” is not a valid error test. Compare like with like: the benefit description and period, the employer's calculation, any payroll entries, the tax-code notice and the HMRC Income Tax account.

Which benefits may appear on a P11D?

Common reportable categories include company cars and fuel, employer-provided private medical insurance, beneficial loans, living accommodation and certain expenses or assets made available for private use. The precise result depends on the facts and statutory exemptions. An employer may also use a PAYE Settlement Agreement for certain minor or irregular benefits, in which case the employee treatment can differ from a benefit that is reported directly on a P11D.

Some payments or benefits are exempt when the conditions are met. Examples can include qualifying workplace parking, certain staff benefits, business expenses and other items described in HMRC's non-taxable-benefits guidance. “It was a work expense” is not enough on its own: the purpose, amount, availability, business necessity and the relevant exemption all matter. If an item is exempt, it may not belong on your P11D, but the employer should still keep the evidence needed to support its treatment.

Salary sacrifice needs particular care. It can change the amount of salary you receive and can create a benefit-in-kind question, but not every salary-sacrifice arrangement has the same tax outcome. Cars, pension contributions, bicycles, childcare history and workplace services can sit under different rules. Check the employer's payroll description and the specific HMRC treatment rather than assume that every salary reduction is tax-free.

How payrolling changes the document

Under voluntary payrolling, an employer can normally collect Income Tax on selected benefits through payroll during the year instead of reporting those benefits on a year-end P11D. The benefit is reflected in taxable pay on payslips, and the employee may not receive a separate P11D for benefits that were payrolled. The employer must still follow the registration, notification and valuation rules. Current official guidance also identifies benefits such as beneficial loans and employer-provided living accommodation that cannot be payrolled through the existing service in the same way.

Payrolling does not make a taxable benefit disappear. It changes when and how the Income Tax is collected. It also does not mean the employer's Class 1A National Insurance process can be ignored. The employer must check the relevant Class 1A reporting even when Income Tax has been collected through payroll.

Official interim guidance says that from 6 April 2027, mandatory payrolling is planned for a range of taxable benefits and expenses, including company cars, car fuel, vans, van fuel and employer-provided medical benefits. Loans and accommodation are described as voluntary in that future guidance. That change falls in the 2027/28 tax year, not the 2026/27 year covered by this page. Employers and employees should not backdate the future process into a current P11D decision; they should follow the latest HMRC instructions for the relevant tax year.

The 2026/27 reporting timeline

For a benefit provided during 2026/27, start with the tax-year dates rather than the calendar year. The year ends on 5 April 2027. The employer generally gives the employee the P11D information and reports the benefits by 6 July 2027. The employer's P11D(b) and Class 1A payment have separate deadlines: HMRC's guidance gives 19 July for a cheque or 22 July for electronic payment following the end of the tax year. These are primarily employer deadlines, but they explain why a P11D-related correction may still be moving through payroll or HMRC after the employee first receives the benefit statement.

The deadline does not mean that every employee will receive a document in exactly the same format. An employer may provide a paper form, a secure digital statement or payroll information explaining that a benefit was payrolled. Save the record and the related payslips rather than relying on a single screenshot of a tax code.

How to check your P11D step by step

The first check is completeness. Did you have more than one job, a company car, medical cover, a loan, accommodation or another taxable benefit? The second is accuracy. Was the benefit available for the whole period, or did you join, leave or change the car during the year? The third is method. Was tax collected through payroll, or was a P11D issued after year-end? These three checks catch more problems than comparing one total with one payslip.

If the benefit was available for only part of the year, do not automatically divide the annual figure by twelve. The official valuation method may use days, periods of availability, payments made by the employee or a statutory formula. Ask payroll for the calculation basis. Keep evidence of the date a car was returned, cover ended, a loan was repaid or accommodation stopped.

What to do when the P11D is wrong or missing

Start with the employer because payroll or the benefits team owns the underlying provision record. Give a precise correction request: identify the benefit, the period, the reported value and the evidence that supports your position. Ask whether the error affects the P11D, payroll, the HMRC submission, Class 1A reporting or all of them. A corrected employee statement is useful, but it is not proof by itself that HMRC's record has already changed.

If the employer cannot correct the issue, check your HMRC Income Tax account and tax code. HMRC may need the employer's correction before it can update the record. Do not simply remove a benefit from a tax-code estimate because it looks high, and do not ignore a missing benefit if you know it was taxable. A wrong code can produce underpayment as well as overpayment.

If the P11D is missing after the employer's reporting deadline, ask when and how the benefit was reported. It may have been payrolled, included in a replacement statement or handled through another approved process. If the explanation does not match your payslips or HMRC record, escalate with the dates and documents. Keep copies of the original and corrected information for your own tax records.

Common mistakes to avoid

Treating every benefit as taxable

Some benefits and expenses can be exempt when every condition is met. Others are taxable but may be dealt with through payrolling or a PAYE Settlement Agreement. The label “benefit” is not enough to determine the result.

Treating every benefit as already payrolled

A benefit appearing on a payslip does not necessarily mean every related reporting obligation is complete. Ask which benefits were payrolled and which remain in the year-end return. This matters especially where different benefits use different systems.

Confusing employee tax with employer National Insurance

The employee's P11D value and the employer's Class 1A liability are connected but not interchangeable. P11D(b) is not an extra employee tax return, and an employee should not calculate their take-home pay by adding the employer's Class 1A amount to the benefit value.

Applying the 2027 rule to 2026/27

The planned mandatory-payrolling changes are important for future planning, but they do not rewrite the current 2026/27 record. Use the process that applied to the benefit in the tax year being checked.

Checking only the P60

A P60 is essential evidence of PAYE pay and deductions, but it is not a complete benefits statement. Keep your P60, P11D or payrolling details, relevant payslips and HMRC notices together.
