Your Sage 50 P11D software update includes the updated legislation for the 2025/2026 tax year.

Key changes include:

• Class 1A NI rate 15%
• Official Interest Rate increased to 3.75%, affecting beneficial loans
• Updated Co2 and zero emissions mileage tables

Fully electric car charging

You need to record mileage for fully electric cars based on whether employees charged at home or with a public charger.

HMRC planned changes

We're working with HMRC on their planned changes affecting P11D submissions from 2027.

HMRC postponed these changes from 6 April 2026 to 6 April 2027.

This doesn't affect v31 of Sage 50 P11D, and you need to process 2025/2026 benefits as normal using v31.
