The changes, which would come into force for the new tax year starting 6 April 2024, would see primary class 1 NICs reduced by 2 percentage points from 10% to 8% (this is the main rate paid by employees) and the main rate for self-employed class 4 NICs reduced from the previously announced rate of 8% down to 6%. This follows earlier NICs reductions announced in the autumn statement and legislated for in the National Insurance Contributions (Reduction in Rates) Act 2023. This reduced primary class 1 NICs from 12% to 10%, starting on 6 January 2024, and had legislated for a reduction in the class 4 NICs from 9% to 8% starting from 6 April 2024. Therefore, as a result of both sets of legislation, class 4 NICs would effectively reduce 3 percentage points for the new tax year.
The government said that the changes would make the tax system fairer and incentivise work. It estimated that they would reduce the NICs paid by 29 million workers. The Office for Budget Responsibility said that the reductions would cost the exchequer £10.3bn a year, but could increase hours worked up to the equivalent of an additional 98,000 full-time workers. However, many commentators, such as the Institute for Fiscal Studies, have highlighted that the changes would have less benefit to some earners and would not counteract the impact of planned tax threshold freezes for most. It said that the majority of workers would still be facing a higher tax burden over the coming years. Concerns have also been raised about future public spending cuts that may be necessary to cover the costs of the government’s tax reduction policies.
The bill passed all its House of Commons stages on 13 March 2024. Labour supported the bill. However, it was not supported by the SNP or the Liberal Democrats. The bill is due to receive its second reading in the House of Lords on 18 March 2024.

This briefing is the fifth of a series on the post-war history of the UK economy. The series proceeds decade-by-decade from the 1950s onwards, providing an overview of the key macroeconomic developments of each decade. This fifth briefing looks at the 1990s. In this decade the UK economy settled into a period of low inflation and steady growth; however, living standards growth was lower and more regionally concentrated than in previous decades.
The Budget Responsibility Bill would require ministers to request an assessment from the Office for Budget Responsibility (OBR) for every major fiscal announcement and give the OBR the power to decide to publish one if the minister failed to request it. This follows the September 2022 ‘mini-budget’. The statement included plans that would have resulted in a projected £45bn reduction in tax income. It did not have an accompanying OBR assessment.
In November 2023, the Harrington review of foreign direct investment made recommendations about how the UK could attract more cross-border investment. The new Labour government has said tackling barriers to investment is a priority.
