A P11D is a form your employer uses to report taxable expenses and benefits provided to you during the tax year. It usually applies when those benefits have not already been taxed through payroll.
Your employer submits the P11D to HMRC and gives you a copy. You should check it carefully, especially if you receive benefits such as a company car, private healthcare, accommodation or interest-free loans.
A P11D is a form used to report certain expenses and benefits you receive from your employer on top of your normal salary.
That might include things like a company car, private medical insurance, accommodation, season ticket loans, fuel, vouchers or other benefits in kind. Your employer uses the P11D to tell HMRC what taxable benefits you received during the tax year, so HMRC can work out whether extra tax is due.
For employees, a P11D can feel confusing because it is not a payslip, a P60 or a tax return. It is a record of taxable benefits. The important thing is that the information on it can affect how much tax you pay, often through your PAYE tax code.
Form P11D is all about employment benefits.
These are the extras you may receive because of your job, on top of your ordinary pay. Some benefits are taxable, which means HMRC needs to know about them.
For example, you might receive:
Not every workplace benefit is taxable, and not every expense needs to appear on a P11D. The rules depend on what the benefit is, how it is used and whether it has already been taxed through payroll.
That is why a P11D is worth checking properly. If the information is wrong, you could end up paying too much or too little tax.
💡 RIFT Recommends: Check your P11D against your real situation. A P11D can affect your tax code, so never just file it away without reading it. Check that the benefits listed are correct, that the dates make sense and that you actually received what the form says you received. If you had a company car for only part of the year, changed roles, gave up a benefit or started paying towards something yourself, those details matter. A small error can follow you into your tax code and affect your take-home pay.
A P11D usually includes basic details about you and your employer, plus information about any taxable benefits provided during the tax year.
That can include:
HMRC uses this information to work out whether extra tax is due.
The form can include many different categories, such as cars, fuel, medical treatment, accommodation, mileage allowances, vouchers, credit cards, loans and other benefits.
Your employer files the P11D, not you.
Employers must report taxable expenses and benefits provided to employees. GOV.UK explains that this can be done either through payroll or online at the end of the tax year. If benefits are not payrolled, employers must complete a P11D for each employee who received taxable expenses or benefits. (GOV.UK)
This can also matter for directors. If you are a director of a limited company and receive benefits from the company, a P11D may be needed.
It is possible to be both employer and employee in your own company, so limited company directors should not assume P11D rules do not apply to them.
The P11D deadline is usually 6 July after the end of the tax year.
For example, for a tax year ending on 5 April, the P11D deadline falls on 6 July.
Employers also need to report Class 1A National Insurance due on taxable expenses and benefits. Where benefits are not payrolled, GOV.UK says employers must submit a P11D and a P11D(b) at the end of the tax year. (GOV.UK)
If an employer misses the deadline or submits inaccurate information, penalties can apply.

A benefit in kind is a non-cash benefit you receive from your employer.
In simple terms, it is something valuable you get because of your job, but not as salary.
Common examples include:
Some benefits are taxed because HMRC treats them as part of your overall reward from work. You may not receive the value as cash in your bank account, but the benefit still has a taxable value.
No, not all work benefits are taxed.
Some benefits and expenses can be exempt, depending on the circumstances. For example, genuine business travel, some business expenses and certain small “trivial” benefits may not create extra tax.
However, the rules are detailed. Something that looks work-related may still be taxable if it has a personal element or does not meet HMRC’s conditions.
That is why employers need to be accurate when reporting benefits, and why employees should check the details they are given.
A P11D can cover a wide range of taxable benefits and expenses.
Common examples include:
As a general rule, if something is provided because of your job and is not simply normal salary, it may need to be considered for P11D reporting.
Yes, it can.
If HMRC knows you receive taxable benefits, it may adjust your PAYE tax code so the tax is collected through your wages.
For example, if you receive private medical insurance through work, HMRC may reduce your tax-free allowance to collect the tax due. This means your monthly take-home pay could change.
If the benefit stops but HMRC is not updated, your tax code may stay wrong. That is one reason people sometimes overpay tax without realising.
Some employers report and tax benefits through payroll instead of using a P11D for each employee at the end of the year.
This is called payrolling benefits in kind.
When benefits are payrolled, the taxable value is added through payroll and tax is collected during the year. GOV.UK says that if a benefit is payrolled, the employer does not need to use form P11D for that benefit, although they must still work out Class 1A National Insurance and complete P11D(b). (GOV.UK)
This can make tax collection feel more immediate, because the benefit is reflected in pay during the year rather than being adjusted later.
However, not all benefits can currently be payrolled. GOV.UK says living accommodation and interest-free or low-interest loans cannot be payrolled under the current guidance. (GOV.UK)
Yes. The alternative is payrolling benefits, where tax on eligible benefits is collected through payroll.
However, the rules are changing. GOV.UK guidance updated in April 2026 says the rules on reporting benefits and expenses are changing, and employers can no longer use the online service to register or cancel registration to payroll benefits and expenses. (GOV.UK)
For employees, the key point is this: whether benefits are reported on a P11D or taxed through payroll, you should still understand what benefits you are receiving and whether the tax looks right.
If your P11D does not look right, raise it with your employer first.
You should check:
If the employer has made a mistake, they may need to correct the P11D. GOV.UK confirms employers can correct errors or report earlier years using online correction forms for P11D and P11D(b). (GOV.UK)
Possibly.
Most people think about P11Ds only when they owe extra tax on benefits, but they can also reveal wider tax code issues.
You might have overpaid tax if:
If your tax code has been wrong because of benefits information, you could be owed money back.
Tax forms are rarely straightforward when you are trying to work out what they mean for your own pay.
A P11D can affect your tax code, your take-home pay and sometimes whether you have paid too much tax. If you are unsure whether your P11D is right, or whether your tax code has been adjusted correctly, RIFT can help you understand what is going on.

A P11D is a form employers use to report taxable expenses and benefits provided to employees or directors during the tax year.
Usually no. Your employer submits the P11D to HMRC and gives you a copy.
Common examples include company cars, private medical insurance, fuel, accommodation, loans, vouchers and certain non-business expenses.
Not always, but it may mean extra tax is due on benefits you received. HMRC may collect this through your tax code.
The usual deadline for employers to submit P11Ds is 6 July after the end of the tax year.
A P60 summarises your pay and tax for the year. A P11D reports taxable benefits and expenses provided by your employer.
Contact your employer and ask them to check it. If they made an error, they may need to correct the form with HMRC.
Yes. If benefits have been reported incorrectly, or your tax code has not been updated properly, you may have paid too much tax.
