What is P11D Form?

The P11D form is a declaration that employers must report annually, listing all taxable benefits, expenses, and other perks provided to employees. Accurate completion of the P11D form is essential to calculate the correct tax liability for both employers and employees. It must be filed by July 6th of each tax year and is a crucial part of payroll and tax returns. Employers can submit the P11D form online through HMRC's PAYE online service, disclosing employee benefits like company cars and health insurance. Utilizing third-party software or opting for paper returns are also viable options.

The P11D(b) form is a separate declaration that accompanies the P11D form. Due on July 6th each tax year, It summarizes the total Class 1A National Insurance contributions due on all the benefits and expenses reported in the P11D forms. Employers must submit both forms together, ensuring that the correct taxes are paid. Payment of Class 1A NICs is due on 22nd July (online) or 19th July (cheque)

  2. Payroll Software: If you have more than 500 employees, fill in and submit the P11D and P11D(b) forms through your payroll software. These software solutions often offer automatic calculations for Benefits in Kind (BiKs) and National Insurance contributions. Additionally, they provide the functionality to generate reports and letters for employees.

P11D Deadline

The P11D form must be submitted by July 6th each tax year to avoid penalties. The submission can be done online, or using third-party payroll software. It serves as the basis for payrolling benefits or filing the P11D(b) form.

P11D Late Filing Penalties:

  1. For late submission of P11D form, a penalty of £100 is imposed per 50 employees for every full month of delay.
  2. In case of late payments for any National Insurance Contributions (NICs) owed, a penalty charge of 5% is incurred after 30 days of the due date. This penalty increases to 10% after 6 months and further escalates to 15% after 12 months, in addition to any accrued interest.

A penalty may apply if you provide inaccurate information in your tax return either carelessly or deliberately, leading to:

  • underpaying taxes
  • over-claiming tax reliefs

PAYE Settlement Agreements (PSAs)

You can make one annual payment to cover all the tax and National Insurance due on minor, irregular or impracticable expenses or benefits for your employees if you have a PAYE Settlement Agreement (PSA) with HMRC.

Under the PSA, you don't need to:

  • put the expenses and benefits through your payroll to work out tax and National Insurance
  • include expenses and benefits in your end-of-year P11D forms
  • pay Class 1A National Insurance on expenses and benefits at the end of the tax year (you pay Class 1B National Insurance as part of your PSA instead)

Payrolling of Benefits

Payrolling of benefits is a convenient alternative to filing the P11D form. It allows tax deductions through payroll software, eliminating the need for form submission. You won't have to submit a P11D if an employee's expenses and benefits have been included in their regular pay through payrolling. Payrolling of benefits means that payroll software includes the value of benefits and expenses into employees' regular pay, rather than reporting them separately to HMRC at the end of the tax year. It's important to note that certain expenses and benefits cannot be included in payrolling. However, unlike the P11D form, if expenses and benefits have been payrolled, you still must submit a P11D(b) form.

Differences Between P11D and P11D(b) Forms

The main difference between the P11D and P11D(b) forms is their purpose. The P11D form is used to report employee benefits, while the P11D(b) form is used to account for tax. Additionally, the filing deadline for both forms is July 6th. The P11D form is necessary when benefits are not payrolled, whereas the P11D(b) form is required when benefits are payrolled. Furthermore, the P11D form is employee-specific, while the P11D(b) form is company-wide.
