HMRC Introduces New Tax Rules Impacting Thousands of Company Car Drivers
This week, HMRC has implemented significant changes to Benefit-in-Kind tax rates, affecting thousands of company car drivers across the UK. The new rules, which came into effect on April 6, 2026, introduce higher tax rates for petrol, diesel, and electric vehicles, with some rates reaching up to 37%.
Major Shift in Tax Reporting and Payment Systems
From April 6, 2027, all employers will be required to payroll benefits in kind, marking a substantial departure from the traditional P11D and P11D(b) reporting cycle. This change necessitates that employers include the taxable value of benefits through payroll in real time, rather than reporting them annually.
Employers who have not yet adopted voluntary payrolling must prepare for significant operational and cash-flow adjustments. They will need to include the cash equivalent of each benefit on employees' payslips, calculate tax and National Insurance contributions (NICs), and report these details via the Full Payment Submission (FPS).
Immediate Financial Implications for Employees and Employers
Employees will now pay income tax on benefits included in each pay cycle, eliminating the previous methods of PAYE coding adjustments or self-assessment. This means that tax deductions will occur more frequently and directly from their salaries.
Employers, on the other hand, will pay Class 1A NICs in real time, rather than in July following the tax year. This shift aims to streamline the tax process but requires immediate financial planning and system updates for many businesses.
