From April 2026, the government will mandate the reporting and paying of Income Tax and Class 1A National Insurance Contributions on benefits in kind via payroll software. This represents a significant change to the current system and should reduce the administrative requirements and simplify the tax system for both employers and employees.
This means that the 2025-26 tax year will be the last year that employers will be able to file P11Ds and P11D(b)s with HMRC in most cases. From April 2026, tax on employment benefits will be collected in real time and not through tax codes in arrears. Class 1A National Insurance contributions will also be collected in real time for each pay period rather than at the end of the year. HMRC has said that this change will remove the need for 4 million end of year returns to be submitted.
HMRC has said that they will engage with stakeholders to discuss their proposals to inform design and delivery decisions and draft legislation will be published later in the year as part of the usual tax legislation process. HMRC will also work with industry experts to produce guidance, which will be made available in advance of 2026.
