Updated October 2026 for the 2026/27 tax year. For the full picture, read our main guide to P11D expenses and benefits.
If your company provided taxable benefits or expenses to employees or directors between 6 April 2026 and 5 April 2027, you will probably need to report them on a P11D. Use this checklist to make sure nothing is missed.
Key dates for 2026/27
- 5 April 2027 – end of the 2026/27 tax year
- 6 July 2027 – submit P11Ds and the P11D(b), and give employees a copy of their P11D information
- 22 July 2027 – pay Class 1A National Insurance (19 July if paying by cheque)
Class 1A National Insurance on benefits is 15% for 2026/27. A late P11D(b) costs £100 per 50 employees for each month or part month it is late.
Checklist: benefits and expenses to review
- ☐ Company cars and private fuel
- ☐ Vans available for private use, and van fuel
- ☐ Private medical or dental insurance
- ☐ Loans to employees or directors, including overdrawn director’s loan accounts, where the total outstanding was more than £10,000 at any point in the year
- ☐ Living accommodation provided to an employee
- ☐ Personal bills paid by the company, such as gym memberships, home utilities or school fees
- ☐ Vouchers and company credit cards used for non-business spending
- ☐ Mileage allowances above HMRC’s approved rates (for cars and vans in 2026/27: 55p a mile for the first 10,000 business miles, 25p after that)
- ☐ Assets given to or used by employees, such as equipment or property for personal use
- ☐ Benefits provided through salary sacrifice, which usually lose their exemption
Usually exempt: no P11D needed
- One mobile phone or SIM card per employee, where the contract is between the company and the supplier
- Trivial benefits costing £50 or less, that are not cash or a cash voucher, not a reward for work and not in the employment contract. Directors of close companies are capped at £300 a year
- Beneficial loans totalling £10,000 or less throughout the whole tax year
- Childcare vouchers up to the exempt limits, but only for employees who joined the scheme on or before 4 October 2018, when the scheme closed to new entrants
- Routine business expenses, such as business travel, covered by an exemption because you reimburse actual costs or pay HMRC’s benchmark rates
Information to gather
Company cars
- Make, model, fuel type and CO2 emissions
- List price when first registered, including accessories
- Date first registered
- Dates the car was available to the employee
- Whether the company paid for private fuel
- Any amounts the employee paid back or contributed
Vans
- Dates available for private use
- Whether private fuel was provided
- Details of any shared vans
Loans
- Balances outstanding during the year and any interest the employee paid
- Any amounts written off
- HMRC’s official rate of interest is 3.75% from 6 April 2026, according to HMRC’s official rates table
Private medical cover
- Premiums or treatment costs the company paid
Payrolling: what changes
- 2026/27: you can only payroll benefits you registered to payroll before 6 April 2026. Everything else goes on a P11D.
- From April 2027: most employers must report medical benefits, company cars, vans and car or van fuel through payroll, deducting the tax in real time. These will no longer go on a P11D after the year end.
- From April 2028: most other benefits follow, except loans and accommodation.
So the 2026/27 P11Ds, due in July 2027, may be the last time you report company cars and medical cover this way. Read more in our P11D guide.
