Tout savoir sur P11D Benefits in Kind
📋Présentation+
Most non-cash benefits provided to employees and directors are taxable and reported annually on the P11D: private medical insurance, company car and fuel benefit values, beneficial loan benefits, and any other perks. The employee pays income tax on the total at their marginal rate; the employer pays Class 1A NIC (15% for 2025/26) on the same total, reported on the P11D(b).
💡 Bonnes pratiques
- Payrolling benefits (registering with HMRC to tax benefits through payroll instead) removes the need for a P11D for those benefits.
- Trivial benefits under £50 each, and certain exemptions like workplace parking, don't need to be reported at all.
- Class 1A NIC is an annual employer cost — budget for 15% of your total benefits bill each July.
🔢 Exemple concret
£1,200 medical insurance + £1,200 car benefit: £2,400 total taxable benefits, £960 income tax at 40%, and £360 employer Class 1A NIC.
