Employers must act now to meet the deadline for paying Class 1A NICs for 2024–25 to avoid HMRC penalties. These contributions are due by 19 July 2025 if paying by post, or by 22 July 2025 for electronic payments. Class 1A NICs apply to most taxable benefits given to employees and directors, including company cars and private medical cover. Employers should ensure payments are correctly referenced using their Accounts Office reference number and clearly mark the relevant tax year. Importantly, July payments always relate to the previous tax year, even if made in the new tax year.

Class 1A NICs are payable by employers on the value of most taxable benefits offered to employees and directors, such as company cars and private medical insurance. They also apply to any portion of termination payments exceeding £30,000, provided Class 1 NICs have not already been deducted.

To ensure payments are correctly allocated, employers should use their Accounts Office reference number as the payment reference and clearly indicate the relevant tax year and month. Note that Class 1A NICs paid in July always relate to the previous tax year.

These contributions typically apply to benefits provided to company directors, employees, individuals in controlling positions, and their family or household members.
