1. Identify every employee who received a taxable benefit in 2025/26.
2. Confirm cash equivalents: company cars, private medical, gym, interest-free loans, professional subscriptions.
3. Check whether you voluntarily payrolled any benefits already.
4. File P11D and P11D(b) by 6 July.
5. Pay Class 1A National Insurance by 19 July (post) or 22 July (electronic).
