It’s P11D Week—a critical reminder that Benefits in Kind are more than just numbers on a form. Behind every box ticked lies a complex web of legislation, liability, and responsibility.

And this year, there’s a twist:📅 The deadline falls on a Sunday (7 July 2025)—adding pressure and reducing room for error.

Don’t Let a Form Become a Fine

At TCW, we’ve seen how easily things can go wrong with P11Ds:

Company car calculations incorrectly split
Salary sacrifice schemes misunderstood
Class 1A NICs underpaid or overlooked
Optional remuneration arrangements mishandled

The result?❌ Penalties of £300 per late form, plus £60 per day❌ Interest on unpaid liabilities❌ Frustrated clients or internal chaos
