Your P11D checklist: July deadline looms!

If your business provides benefits or expenses to employees or directors — such as company cars, private medical insurance, or interest-free loans — it’s essential that these are reported to HMRC using form P11D. With the 6 July deadline fast approaching, here’s a quick checklist to help you stay compliant and avoid penalties.

✅ 1. Check Who Needs a P11D

Any employee or director earning more than £8,500 annually and receiving benefits in kind needs a P11D.
Don’t forget about company directors, even if they’re the only employee.

✅ 2. Gather Accurate Benefit Details

Ensure you have up-to-date records for:

Company cars or fuel: CO² emissions, list price and availability dates.
Private medical insurance: full cost to the business.
Loans to employees: especially those over £10,000 at any point in the tax year.
Assets made available for personal use: property.
Living accommodation: rent paid, value of the property, and any services provided.

✅ 3. Report Mileage and Travel Expenses

HMRC allows tax-free mileage rates, but excess mileage or reimbursed travel over the approved rates must be reported.
Don’t include business expenses reimbursed with proper receipts unless they exceed HMRC’s approved limits.

✅ 4. Review Payrolled Benefits

If you’ve opted to payroll benefits, they don’t need to be included on P11Ds, but you must still submit a P11D(b) to report Class 1A National Insurance contributions.

✅ 5. Submit the P11D(b)

This form summarises the total benefits you’ve provided and calculates the Class 1A NIC due.
Even if you’re submitting no P11Ds, you must still file a P11D(b) declaration if HMRC has asked you to.

✅ 6. Meet Deadlines

✅ 7. Give Copies to Employees

You must provide employees with copies of their individual P11D forms by 6 July.
