P11D & Benefits in Kind UK 2025/26

Common Taxable Benefits

EV Salary Sacrifice — The Tax Sweet Spot

Electric company cars have the lowest BIK rates in UK history. 2025/26 schedule:

• 2024/25: 2% BIK
• 2025/26: 3% BIK
• 2026/27: 4% BIK
• 2027/28: 5% BIK
• Petrol/diesel: 17-37% BIK depending on emissions

A £45,000 Tesla Model 3 in 2025/26: BIK = £45k × 3% = £1,350. Higher-rate tax on this = £540/year (£45/month). Compare with personal lease of £500/month — salary sacrifice EV could be £200/month cheaper after tax savings.

Tax-Free Benefits

• Workplace pension contributions (employer\'s contribution)
• Cycle to Work scheme bikes (up to RRP via salary sacrifice)
• One mobile phone per employee
• Workplace nursery (employer-provided)
• Job-related training
• Free meals in staff canteen (open to all)
• Eye tests (DSE users)
• Trivial benefits under £50 (e.g. flowers, Christmas hampers)
• Parking at or near workplace
• Long-service awards (after 20 years, up to £50/yr)

Company Car BIK in Detail

A company car's annual taxable value is calculated as list price (P11D value) × appropriate percentage. The list price includes VAT, delivery charges and any factory-fitted options costing £100 or more, before any discounts the employer negotiated. The appropriate percentage is set by CO2 emissions:

• 0 g/km (pure EV): 3% in 2025/26, rising to 4% in 2026/27 and 5% in 2027/28
• 1-50 g/km plug-in hybrids: 5%-19% depending on electric range
• 51-54 g/km: 15%
• 55+ g/km: scales by 1% per 5 g/km up to a maximum of 37%
• Diesel without RDE2: add 4% surcharge (capped at 37%)

If the employer also provides free fuel for private mileage, the fuel benefit charge is £28,200 × the same percentage for 2025/26. For most company-car drivers this only makes sense if they do over 10,000 private miles per year.

Payrolling Benefits — Mandatory from April 2026

HMRC confirmed at Autumn Budget that payrolling of most Benefits in Kind becomes mandatory from April 2026. Instead of reporting on P11D after year-end, the cash equivalent of each benefit must be added to taxable pay each pay period and taxed in real time through PAYE. Employer-provided loans and accommodation are the only major exceptions in the first wave.

For employers this means registering for payrolling before 5 April 2026 and updating payroll software. For employees, it means BIK tax comes out of each payslip rather than being collected via an adjusted tax code later. Class 1A NI (15%) is unaffected — still paid annually by 22 July.

Reporting Timeline

• 5 April: end of tax year — benefits crystallised
• 31 May: P60 issued to employees
• 6 July: P11Ds filed with HMRC; copy issued to employees
• 19 July: Class 1A NI must be paid by post; 22 July by electronic transfer
• HMRC adjusts the employee's tax code at the next available point to recover BIK tax (where benefits are not payrolled)

Late or incorrect P11Ds attract penalties starting at £100 per 50 employees per month, escalating quickly. Employers should keep BIK records for at least 3 years after the relevant tax year.

Trivial Benefits Rules

Small employer-provided perks can be tax-free if they meet all four trivial benefits conditions:

• Cost £50 or less per recipient (including VAT)
• Not cash or a cash voucher
• Not provided as a reward for work or performance
• Not stipulated in the employment contract

There is no annual limit for general staff, but directors of close companies are capped at £300/year of trivial benefits. Typical examples: birthday flowers, a Christmas hamper, a meal out to celebrate completing a project.

Class 1A NI — Employer\'s Cost

Employers pay Class 1A NI at 15% (from April 2025; was 13.8%) on most taxable benefits. Due by 22 July following the tax year, paid through PAYE. This is on top of the income tax employees pay on the benefit value.

Common Mistakes

• Forgetting beneficial loans: any cumulative employer loan above £10,000 at any point in the year triggers BIK on the HMRC official rate (currently around 2.25% for 2025/26)
• Adding all options to list price incorrectly: only factory-fit options of £100+ count; dealer-fit accessories follow different rules
• Forgetting to claim back days the car was unavailable (over 30 consecutive days reduces the BIK pro-rata)
• Treating gym membership as health benefit: only employer-provided medical screening and certain rehabilitation expenses are exempt
• Missing the trivial benefits cap on directors — £300/year limit, easy to breach with multiple small gifts
