The 12% to 10% employees national insurance rate cut first announced in the Autumn Statement came into effect in January. This means that many employees will have seen a boost in their take home pay in their January pay packet.
HM Revenue and Customs launched a tool (https://www.tax.service.gov.uk/estimate-jan-24-nic-changes) that enabled workers to estimate how the changes will affect them.
The government is naturally keen to emphasise its generosity in this measure and have claimed that a household with two average earners will be starting to see a yearly benefit from the cut of almost £1,000. Naturally, how much benefit earners actually receive will depend on how near the average their earnings are.
The rate reduction only applies to employees’ national insurance, and not employers’ national insurance. This means there is no direct saving for businesses. However, with many businesses under stress to grant pay rises that will combat the increasing cost of living, the reduction may prove to be a helpful component of pay strategy.

UK businesses are facing a “cost of business crisis”, according to the British Chambers of Commerce (BCC). Its new cost-stack calculator shows government policy alone has pushed up an average firm's expenses by 70% over the past decade, adding roughly £827,000 a year in costs for a typical mid-sized business. About a quarter of the rise stems from the increase in employer National Insurance contributions, with the higher minimum wage and mandatory pension auto-enrolment also major contributors.
Under Making Tax Digital (MTD) for Income Tax, sole traders and landlords with income of more than £50,000 have been required to keep digital records and send quarterly updates to HMRC since 6 April 2026.
