From 6 April 2026, payrolling benefits in kind (BIK) is no longer optional for most UK employers; it is mandatory. The P11D form, which has been the standard mechanism for reporting employee benefits to HMRC, is effectively being phased out for the majority of benefit types. Employers who have not already registered to pay their benefits must now do so as the default position.<\/p>

For accounting practices, this is a significant operational change across the employer client base. Clients who have been filing P11D returns annually, often as a year-end task managed by the practice, now need to include the cash equivalent value of their employee benefits included in payroll every single month. This changes the workflow, software requirements, employee communications, and the timing of tax deductions for every affected employer.<\/p>

This guide covers what the change means in practical terms, which benefits are affected, and what accounting practices need to do now to keep employer clients compliant.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Mandatory BIK Payrolling Changes Explained<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Payrolling BIK has been available on a voluntary basis since 2016. Many employers, and the accounting practices that manage their payroll, chose to continue with the P11D approach because it was familiar, their software supported it, and there was no regulatory pressure to change. From April 2026, HMRC has removed that choice for most benefit types.<\/p>

The practical shift is substantial. Under the old P11D model, the tax on most employee benefits was collected once a year, either through a year-end Self Assessment adjustment or via the employee’s PAYE tax code in the following year. Under mandatory payrolling, that tax is collected monthly through the payroll, in real time, as the benefit is provided. For practices providing\u00a0outsourcing for accountants<\/a>, including running payroll on behalf of employer clients, this is a fundamental change to how BIK is processed, reported, and reconciled.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

One important point that catches practices out: Class 1A National Insurance on payrolled benefits is not collected through the payroll. It is still reported and paid via the P11D(b) return by 6 July each year. The P11D form is abolished for most benefits, but the P11D(b) survives. Employer clients need to understand this clearly to avoid a missed payment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Not all benefits in kind fall within the mandatory payrolling requirement. The table below sets out the most common BIK types, their payrolling status from April 2026, and the key calculation point for each:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

This table covers the most common BIK types. Practices should verify the latest HMRC exemption list for less common benefits before advising clients.<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Living accommodation is the key exception<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Living accommodation provided by an employer remains exempt from mandatory payrolling and must still be reported via P11D for the 2026\/27 tax year. HMRC has confirmed this exemption will continue until a future date when the technical infrastructure for payrolling accommodation benefits is in place. Practices with employer clients providing accommodation should ensure P11D reporting for this benefit is maintained correctly alongside the payrolled BIK for other benefits.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

BIK Payrolling Compliance Risks for Accounting Practices<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Beyond the technical setup of payrolled BIK, there are several compliance implications that accounting practices need to work through for each employer client:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

PAYE Tax Code Adjustments<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

When a benefit is payrolled, the tax on it is collected through the payroll rather than through the employee’s PAYE code. HMRC should automatically remove payrolled benefits from the employee’s code, but in practice, practices need to verify that codes have been updated to avoid double-taxing employees on the same benefit. This is one of the most common errors in the transition period and one that generates employee complaints and code correction requests.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Monthly Cash Equivalent Calculation\n<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The annual cash equivalent value of each payrolled benefit must be divided by the number of pay periods in the year and included in the payroll each month. For variable benefits, where the value changes during the year, such as a car benefit where the vehicle changes, the practice needs a mechanism to update the monthly value promptly. Getting this right requires\u00a0payroll benefits<\/a>\u00a0to be recorded and maintained accurately throughout the year, not just at year-end.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

Employee Communication<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Employees who previously saw their benefit tax collected as a code adjustment or Self Assessment payment will now see a change in their monthly net pay. For some employees, particularly those with company cars or private medical insurance, the monthly tax deduction through the payroll may be noticeably different from what they were used to. Employer clients need to communicate this change to staff proactively, and practices should provide them with clear, accessible explanatory material to share.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

PAYE Settlement Agreements\n<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Where employers currently use a PAYE Settlement Agreement (PSA) to cover certain minor or irregular benefits, they need to review whether any of those benefits now fall within the mandatory payrolling requirement. Benefits that must be paid cannot be covered by a PSA. Practices should audit each employer client’s PSA arrangements and advise on any necessary amendments.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

For practices managing payroll for a large number of employer clients, the BIK transition adds meaningful volume to the monthly payroll cycle. Each employer with payrolled benefits requires an updated payroll setup, a monthly value calculation, and ongoing verification that codes and RTI submissions are correct. Practices using\u00a0outsourced payroll services<\/a>\u00a0can manage this transition more efficiently, with specialist payroll teams handling the technical setup, monthly processing, and RTI submissions while the practice focuses on advising clients on the compliance implications.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Managing Monthly Payroll with Payrolled BIK \n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Once the initial setup is complete, payrolled BIK becomes part of the regular monthly\u00a0payroll processing<\/a>\u00a0cycle. Each pay period, the practice needs to:<\/p>

  1. Include the monthly BIK cash equivalent value for each employee and each benefit in the payroll calculation.<\/li>
  2. Deduct the correct amount of income tax on the payroll benefit through the payroll, in addition to tax on salary.<\/li>
  3. Report the payrolled benefit values through RTI on the Full Payment Submission (FPS) each pay period.<\/li>
  4. Monitor for changes to benefit values during the year, new starters, vehicle changes, cover level amendments, and update the monthly values accordingly.<\/li>
  5. Maintain accurate records of each payrolled benefit by employee throughout the year, ready for the P11D(b) Class 1A NI calculation at 5 April.<\/li>
  6. File the P11D(b) by 6 July each year and pay any Class 1A NI due by 22 July (19 July if paying by cheque).<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    A Compliance Deadline That Requires Practice Action Now\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    Mandatory BIK payrolling is not a change that employer clients can manage independently without guidance. Most do not know which of their benefits must now be payrolled, how to calculate the monthly values, how to update their PAYE codes, or what happens to their P11D(b) obligations. The accounting practice is the natural first point of contact, and the quality of the transition depends heavily on how clearly and proactively that guidance is delivered.<\/p>

    For practices managing payroll across a large employer client base, the operational impact of this change is significant. Every employer with active benefits arrangements needs their payroll setup reviewed, updated, and tested before the next pay run. Building that capacity, whether through internal resources or a specialist delivery partner, is the practical challenge that sits behind the compliance requirement.<\/p>

    At\u00a0Befree<\/strong>, we work alongside UK accounting practices to manage exactly this kind of payroll transition, handling the setup, processing, and RTI compliance so that your team can focus on the advisory conversations that employer clients need right now.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Yes, for most benefit types, payrolling BIK is mandatory from 6 April 2026. Employers who have not previously registered to pay their benefits must now do so as the default position. There are a small number of exempt benefit types, most notably living accommodation, that cannot currently be payrolled and must still be reported via P11D. HMRC has confirmed that the P11D form will be abolished for all currently eligible benefit types from this date, though the P11D(b) for Class 1A NI reporting remains in place.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

    The P11D form for reporting individual employee benefits is abolished for most benefit types from April 2026; those benefits must now be payrolled. However, the P11D(b) form, which reports the employer’s Class 1A National Insurance liability on benefits in kind, is not abolished. Employers must still file the P11D(b) by 6 July each year and pay the Class 1A NI due by 22 July. The key distinction is that P11D reports individual employee BIK values; P11D(b) reports the employer’s aggregate Class 1A NI liability. The former is going; the latter is staying.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

    How is the monthly payroll BIK value calculated? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
    \n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    The monthly payrolled BIK value is calculated by taking the annual cash equivalent value of the benefit, as defined by HMRC’s valuation rules for each benefit type, and dividing it by the number of pay periods in the tax year. For monthly-paid employees, that means dividing the annual value by 12. For weekly-paid employees, by 52. Where the benefit value changes during the year, for example, when an employee changes their company car, the monthly value must be updated from the point the change occurs, and the revised figure must be reflected in the payroll and RTI submission for that period.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

    When a benefit is payrolled, HMRC should automatically update the employee’s PAYE tax code to remove the deduction that was previously built in to collect the benefit tax. However, this does not always happen promptly or accurately. Practices should verify, for every affected employee, that the PAYE code has been updated correctly before the first payrolled BIK pay run. If the code has not been updated and the benefit tax is being collected both through the payroll and through the code, the employee will be double-taxed, a situation that generates immediate complaints and requires a correction request to HMRC.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

    Benefits that are subject to mandatory payroll from April 2026 cannot be covered by a PAYE Settlement Agreement (PSA). A PSA is designed to settle tax on minor, irregular, or impracticable-to-allocate benefits, categories that do not include the commonly payrolled BIK types such as company cars, private medical insurance, or gym memberships. Employers with PSAs that currently cover benefits, now subject to mandatory payrolling, should review and amend those agreements. The PSA can continue to cover benefits that remain outside the payrolling requirement, but must be updated to remove those that have moved into payrolling.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

    This is a practical issue for some smaller employers whose payroll software does not support payroll BIK values in the RTI Full Payment Submission. Practices should identify any employer clients in this situation and advise them to either upgrade their payroll software to an HMRC-recognised product that supports payrolled BIK or move to a managed payroll service that handles BIK as part of the standard monthly processing cycle. Running payrolled BIK through a system that cannot properly capture and report the values in RTI creates a compliance risk that HMRC’s real-time data matching will surface quickly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t
