Ni From April 2025

Ni From April 2025. For example, the 2023 to 2025 tax year starts on 6 april 2023 and ends on 5 april. There will be some new national insurance rates and thresholds from 6 april 2025.

From 6 april 2025, the combined effect of measures from both fiscal events is that the main rate of class 4 nics will reduce from 9% to 6%, and class 2 nics will. Ni has already been cut twice in 2025, but previous changes to the way tax is calculated mean the amount many people pay overall has risen.
