Mandatory BIK payrolling: What the new phased approach means for employers

The government’s plans to modernise the way Benefits in Kind (BIK) are reported have taken another important step forward, with confirmation that mandatory payrolling will now be introduced in phases rather than as a single wholesale change.

For employers, the revised timetable provides additional time to review processes, systems and reporting requirements ahead of implementation.

A more gradual transition

Rather than bringing almost all taxable benefits into payroll from April 2027, the government has now confirmed a staged approach.

• From April 2027, mandatory payrolling will apply to some of the most commonly provided employee benefits, including company cars, vans, fuel benefits and private medical insurance.
• Other taxable benefits will follow from April 2028, while employment-related loans and living accommodation will remain outside the mandatory regime for the foreseeable future.

The phased approach introduces the changes in stages, giving employers an opportunity to focus on specific benefit categories before wider requirements are introduced.

Why mandatory payrolling matters

For decades, many employers have relied on the annual P11D process to report employee benefits after the end of the tax year.

Mandatory payrolling changes this approach by moving benefit reporting closer to real time. Instead of waiting until year-end, taxable benefits will be processed through payroll during the tax year, allowing tax liabilities to be collected as earnings are paid.

The long-term objective is a more streamlined system that reduces year-end administration and improves the accuracy of employee tax deductions.

However, achieving that outcome requires changes to payroll systems, data collection processes and internal controls.

The benefits most employers should focus on first

The first phase of the rollout targets benefits that are generally easier to value and track throughout the year.

Company cars, vans, fuel benefits and private medical insurance are already widely reported and supported by established payroll processes, making them logical starting points for mandatory payrolling.

For employers that provide these benefits, the next twelve months present an opportunity to review existing reporting methods, assess payroll software capabilities and identify any process gaps before implementation begins.

Early preparation can help employers identify potential process changes and ensure systems are ready ahead of the new requirements.

How employers can prepare

Although the first phase does not begin until April 2027, preparation should start much sooner.

Key areas to review include:

• Current benefit reporting arrangements
• Payroll software readiness
• Data accuracy and benefit valuation processes
• Internal payroll and HR workflows
• Employee communications and education

Organisations with large company car fleets or extensive healthcare benefit schemes may need to begin planning particularly early to ensure a smooth transition.
