With mandatory payrolling of Benefits in Kind (BiKs) set to take effect in April 2027, UK employers will soon be required to process and deduct tax through payroll in real-time. While many business owners have interpreted this update as the total abolition of P11D reporting, the reality is a shift in methodology rather than an elimination of compliance. Moving away from traditional year-end reconciliations, businesses must now ensure that employee benefits are accurately calculated and reflected within each regular payroll cycle.
Understanding the Current P11D Framework
P11D is the statutory form employers use to report taxable BiKs and expenses provided to employees during a tax year.
Common examples of reported benefits include:
- Private Medical Insurance
- Company Cars
- Fuel Benefits
- Employer-Provided Accommodation
- Interest-Free or Low-Interest Loans
- Other taxable employee benefits
Under the traditional system, employers submit these forms once the tax year has concluded. HMRC then adjusts employees’ PAYE tax codes to collect the tax due in subsequent tax periods. However, from April 2027, this familiar administrative process will change fundamentally.
What Is Changing in April 2027?
Starting April 2027, the government will phase in mandatory payrolling over two years. In this first phase, key taxable benefits such as company cars and private medical insurance must be reported in real-time through payroll, replacing the traditional year-end P11D submission.
<Example>
For example, suppose an employer provides an employee with private medical insurance worth £3,000 annually.
Current System
Annual Benefit Value: £3,000
Monthly Payroll Impact: None (Reported on a P11D year-end)
Tax Collection: Adjusted via tax codes in the following year
After April 2027
Annual Benefit Value: £3,000 ÷ 12 months
Monthly Payroll Impact: £250 included each month
Tax Collection: Reported and deducted via PAYE in real-time to HMRC
Consequently, employees will pay the tax due on their benefits monthly as the perk is received. From this perspective, it is far more accurate to view this reform not simply as the “abolition of P11D,” but as a fundamental transition to a real-time benefit reporting system.
Key Benefits Subject to Mandatory Payrolling from April 2027
The following Benefits in Kind (BiKs) must be reported and processed directly through payroll (PAYE) starting April 2027:
1. Car and Transport-Related Benefits
- Company Cars
- Car Fuel Benefits
- Company Vans
- Van Fuel Benefits
2. Medical and Health-Related Benefits
- Private Medical Insurance
- Other Employer-Provided Medical Perks
Current Exceptions & Future Timeline
While most remaining benefits are scheduled to come under the PAYE framework in April 2028, the rollout timeline for the two exceptions listed below has yet to be determined.
- Employer-Provided Living Accommodation
- Beneficial Loans (Interest-free or low-interest loans)
The Critical Importance of Real-Time Information Sharing
From April 2027, all relevant data must be communicated well ahead of the monthly payroll cut-off date. For larger organisations in particular, ensuring that the internal finance team or external tax agents receive this information on time will be the ultimate key to compliance.
Under the current framework, confirming benefit details late in the year rarely caused significant issues, as long as the data was consolidated before the year-end P11D submission deadline.
However, starting April 2027, tax on BiKs must be calculated alongside each regular salary payment. Any delays in reporting internally will directly translate into payroll errors and potential legal or financial penalties for the business.
Action Plan: What Employers Should Check Right Now
While April 2027 may seem far off, establishing a robust system requires careful planning. To mitigate compliance risks, we strongly recommend that business owners proactively review the following areas today:
- Audit Current P11D Items
- Review Salary Sacrifice Schemes
- Upgrade Payroll Software
- Streamline Team Workflows
- Consult Your Accountant
Ultimately, the transition away from the P11D in 2027 is not merely the abolition of a statutory form. Instead, it marks the start of a new payroll system that requires the real-time management of taxable expenses and benefits. If your business is unfamiliar with these changes, consulting with specialized corporate accountants like the team at BH1 Accounting is an excellent way to ensure full compliance.
