Our UK employer national insurance comparison calculator helps you assess the impact to your business of the April 2025 changes to employer national insurance contributions.
From April 2025, employer’s national insurance contributions are increasing from 13.8% to 15%, while the threshold above which contributions are made is decreasing from £9,100 to £5,000 annually.
