When it comes to payroll and employee benefits, businesses are already navigating rising employment costs, increasing compliance requirements, and ongoing legislative change. While 2027 may still seem some way off, one significant reform is already on the horizon and employers should start preparing now.

From April 2027, the Government plans to make the reporting of Benefits in Kind (BiKs) through payroll mandatory, fundamentally changing how employers manage employee benefits and expenses. For many organisations, this will effectively signal the end of the traditional P11D process as we know it.

While the change is designed to simplify tax reporting and improve accuracy, it will require businesses to review their processes, systems, and payroll operations well in advance.

What is a P11D?

A P11D is the form employers currently use to report Benefits in Kind provided to employees. These benefits can include company cars, private medical insurance, fuel benefits, low-interest loans, and other perks provided in addition to salary.

Under the current system, employers submit P11Ds after the end of each tax year. HMRC then uses this information to adjust employees’ tax codes and collect any tax owed on those benefits.

For payroll and finance teams, the annual P11D process can be time-consuming. Gathering information, validating benefit data, calculating values, and meeting submission deadlines often creates a significant administrative burden during an already busy period.

What’s Changing in 2027?

The Government’s proposal will make the payroll reporting of Benefits in Kind mandatory from April 2027.

Many employers already choose to payroll benefits voluntarily, but from 2027 it is expected to become the standard reporting method for most taxable benefits.

Rather than reporting benefits after the end of the tax year, employers will process the taxable value through payroll during the year. Employees will therefore pay the correct tax in real time through their monthly pay, removing the need for HMRC to make adjustments later through tax codes.

The aim is to create a more efficient and transparent system that benefits employers, employees, and HMRC alike.

Why Is This Change Being Introduced?

The move forms part of HMRC’s wider digitalisation strategy and ongoing efforts to modernise the UK tax system.

By collecting tax on benefits through payroll, HMRC hopes to improve accuracy, reduce administrative complexity, and minimise situations where employees receive unexpected tax code changes months after receiving a benefit.

For employees, this should mean fewer surprises and a clearer understanding of how workplace benefits affect their take-home pay. For employers, it has the potential to remove a significant year-end reporting exercise and streamline compliance processes.

What Will This Mean for Businesses?

Although the change should ultimately simplify reporting, it will require organisations to rethink how benefit information is managed.

Many businesses currently record benefits across multiple systems, spreadsheets, finance functions, or external providers. In some cases, payroll teams only receive benefit information once a year during the P11D process. That approach will no longer be sufficient.

Benefit information will need to be captured accurately and shared with payroll throughout the year to ensure the correct tax is applied at the right time.

Data Accuracy Will Be Critical

The quality and timeliness of benefit data will become even more important. Incorrect information could result in employees paying too much or too little tax, creating additional administration and potentially damaging employee confidence.

Businesses should review how benefit data is currently captured and whether existing processes provide the accuracy required for real-time reporting.

Greater Collaboration Between Teams

Payroll cannot manage this change alone.

HR teams, finance departments, payroll professionals, and benefit providers will all need to work together to ensure information flows efficiently throughout the year.

Organisations with disconnected systems or heavily manual processes may need to review how information is shared across departments.

Technology Will Play a Key Role

Modern payroll software will be central to managing the transition successfully.

Businesses should engage with their payroll providers early to understand how systems will support mandatory payrolling requirements and what changes may be needed before implementation.

Integrated payroll and HR systems can help reduce manual administration while improving compliance and visibility.

Employees Will Need Clear Communication

As benefits begin appearing differently within payroll calculations, employees are likely to have questions about changes to their payslips and tax deductions.

Clear communication will help employees understand what is changing and why, reducing confusion and unnecessary payroll queries.

Why Employers Should Start Preparing Now

Although April 2027 may feel distant, major payroll reforms take time to implement successfully.

Businesses that start planning now will have the opportunity to review processes, identify risks, test systems, and train teams gradually rather than facing a rushed implementation closer to the deadline.

We have seen this before with pension auto-enrolment and Real Time Information (RTI). The organisations that achieved the smoothest transitions were those that prepared early and treated compliance changes as strategic projects rather than last-minute administrative tasks.

More Than a Compliance Requirement

While much of the focus will be on compliance, this change also presents an opportunity.

Mandatory payrolling of benefits encourages businesses to modernise processes, improve data quality, reduce manual administration, and strengthen collaboration between payroll, HR, and finance teams.

At PayEscape, we are already helping clients understand the impact of the upcoming reforms and assess their readiness for the transition. Our advice is simple: don’t wait until 2027 to start planning.

The move away from traditional P11Ds represents one of the most significant payroll reporting changes in recent years. With the right preparation, businesses can not only remain compliant but also create more efficient, accurate, and future-ready payroll operations.

The end of P11Ds may be approaching, but for prepared businesses, it could mark the beginning of a smarter way of managing employee benefits.
