P11D
Employee expenses and benefits
Our P11D filing services help businesses manage reporting obligations efficiently, including preparation of P11D forms and P11D(b) returns.
What is a P11D?
A P11D form is used to report employee benefits and expenses that have not been processed through payroll. Common examples include company cars, private medical insurance and reimbursed expenses.4 5Employers must submit these details to HMRC annually and provide relevant information to affected employees.
It reports any benefits your staff have received and any expenses payments that have been made to them other than those put through payroll.
Depending on the size of your business, this can be a substantial bureaucratic burden, especially as you need to ensure those employees who file a self-assessment tax return also receive a copy for their records.

Our service includes:
• Preparation of P11D forms
• Completion of P11D(b) returns

Horsfield & Smith can take this task off your plate, tackling the paperwork and filing on your behalf, including the subsidiary P11D(b) form recording any additional National Insurance contributions (NICs) due. Proper reporting of benefits can also support wider tax planning and compliance objectives.
We’ll ensure you meet government deadlines and that tax code errors are avoided.
We can also help you understand what can and cannot be claimed as a business expense, what counts as a ‘taxable benefit in kind’ and how you can avoid incurring additional tax obligations through incorrect administration of employee benefits.
