What is a P11D? UK 2026/27 Guide
What it is
The P11D reports 'benefits in kind' (BIK) — non-cash perks of employment that have a taxable cash value. Common items: company cars (taxed on a percentage of list price based on emissions), private medical insurance (taxed on the premium cost), interest-free loans over £10,000, accommodation, fuel benefit, and gym memberships if not exempt. Each benefit type has specific HMRC rules for valuation.
Who needs this
P11Ds are issued only to employees who receive taxable benefits. If your only employment income is salary with no extras, you won't have a P11D. Common P11D recipients: employees with company cars, those on enhanced private medical schemes, executives with various perks, and anyone receiving director's loan benefits. Your employer files one P11D per employee receiving benefits.
When you'll see it
By 6 July after the tax year ends — significantly later than the P60 (31 May) because employers need time to value benefits accurately. The P11D figures then trigger a tax code adjustment (often a new K code) for the current tax year, recovering tax on benefits via PAYE. Some employees also receive a P11D(b) which is the employer's overall benefits return.
How to get it
Your employer issues the P11D directly. If you've not received yours by 6 July, contact HR/payroll. If you've left the employer, they should still send the P11D to your last known address — update your address with their HR or via HMRC personal tax account if you've moved. HMRC also receives a copy and can confirm figures via your tax account.
Common issues
Common P11D issues: (1) wrong company car valuation (CO2 emissions used wrong band — check the registration document), (2) medical insurance figure too high (usually because it includes spouse/family value when it shouldn't), (3) P11D received but no tax code change (HMRC delay — often takes 2-3 months for code to update), and (4) P11D shows benefits you didn't have (employer payroll error — get it corrected, otherwise you'll pay tax on benefits you never received).
Recruiter pro tip
P11D figures often surprise people because the cash value of benefits is higher than perceived. A £35,000 company car might add £8,000-£10,000 to your taxable income. A senior executive's private medical scheme might add £2,000-£4,000. Before accepting a job with benefits, calculate the post-tax cost using our take-home pay calculator. Sometimes a higher cash salary is worth more than the equivalent benefits package.
