For UK employers, the P11D submission deadline of 6th July 2026 is an important date that shouldn’t be overlooked. If you have provided employees or directors with benefits in kind during the 2025/26 tax year, you may be required to submit P11D forms to HMRC.
Missing the deadline or submitting incorrect information can result in penalties, making it essential to prepare well in advance.
What is a P11D?
A P11D is a form used to report taxable benefits and expenses that have been provided to employees or directors but are not processed through payroll.
Common benefits that may need to be reported include:
- Company cars and fuel
- Private medical insurance
- Interest-free or low-interest loans
- Living accommodation
- Assets transferred to employees
- Certain travel and entertainment expenses
- Other employee benefits not included in payroll
If you have registered for payrolling benefits, some benefits may no longer require reporting on a P11D, but other obligations may still apply.
Who Needs to Submit a P11D?
You may need to submit a P11D if:
- You are an employer who has provided taxable benefits or expenses.
- The benefits have not been taxed through payroll.
- You employed directors or employees who received reportable benefits during the tax year.
Employers are also required to submit a P11D(b) to declare the total amount of Class 1A National Insurance contributions due on these benefits.
Important Dates
Here are the key dates to remember:
- 6th July 2026 – Deadline for submitting P11D and P11D(b) forms to HMRC.
- 22nd July 2026 – Deadline for paying Class 1A National Insurance Contributions electronically (19th July if paying by post).
Leaving your submissions until the last minute increases the risk of errors and unnecessary stress.
What Happens if You Miss the Deadline?
HMRC can charge penalties for late or incorrect submissions. In addition to financial penalties, inaccurate reporting may lead to further enquiries and additional administration.
Submitting your forms correctly and on time helps keep your business compliant and avoids unnecessary costs.
