The latest HMRC figures for November showed the tax take from employer NI was up 23% at a record £93.7bn haul from April to November 2025, up from £75.9bn the previous year, illustrating the impact of the chancellor’s decision to hike employer NI in her first Budget in October 2024.

There was a big increase in employer national insurance contributions (NICs) year on year, with £2.4bn more being collected in November 2025 compared to the same period the year previous. In 2024, takings stood at £9.2bn, compared with £11.6bn just a year later.

This rise reflects the NI hike announced in the 2024 Budget, which saw increases in the rate of employer NICs from 13.8% to 15% from April 2025 and halving of allowances for lower paid workers.
