Employers must pay Class 1A NICs for 2024–25 benefits by 19 July (post) or 22 July (electronic). These apply to perks like company cars and private health cover—late payment risks penalties from HMRC.

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

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

There are three key dates employers must remember for the 2024–25 Class 1A NICs. Forms P11D and P11D(b) must be submitted by 6 July 2025. Postal cheque payments must reach HMRC by 19 July 2025, and electronic payments must clear into HMRC’s bank account by 22 July 2025.

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