Potential Class 1A National Insurance
Employers usually need to report expenses and benefits by 6 July after the end of the tax year. Class 1A National Insurance is normally payable by 22 July if paying electronically, or 19 July if paying by cheque. For the 2025/26 tax year, HMRC confirms the P11D and P11D(b) filing deadline is 6 July 2026.
Not sure whether a benefit needs to be reported?
Unsure if your company car, medical insurance or director benefit creates a tax charge?
Need your P11D prepared and filed correctly?
We can help.
A P11D is used to report taxable expenses and benefits provided to employees or directors that have not already been payrolled. HMRC says employers may need to report benefits such as company cars, health insurance and interest-free loans.
You may need to submit a P11D if you provided taxable benefits or expenses to an employee or director and those benefits were not taxed through payroll.
A P11D(b) tells HMRC how much Class 1A National Insurance the employer owes on taxable benefits. HMRC states that employers must submit a P11D(b) where Class 1A National Insurance is due.
HMRC says you do not usually need to submit a P11D for benefits and expenses that are already payrolled.
Yes. We can help calculate, review, prepare and file your P11D and P11D(b), with clear fixed-fee support.
