The Chancellor has announced notable alterations to national insurance contributions (NIC) affecting both self-employed taxpayers and employees. The primary Class 1 NIC rate for employees, applicable to earnings between £12,570 and £50,270 annually, will see a reduction from 12% to 10%, effective from 6.1.24 instead of the usual next tax year commencement. Employers should update payroll software before the January pay run to implement the correct Class 1 NIC deduction.

For self-employed taxpayers, the Class 4 NIC main rate will decrease by 1%, moving from 9% to 8% starting on 6.4.24. Furthermore, self-employed traders with profits exceeding £12,570 will no longer be obligated to pay Class 2 NIC but will retain access to contributory benefits, including the state pension. Those with profits between £6,725 and £12,570 can continue on this basis, while those with profits below £6,725 can voluntarily pay Class 2 NIC to safeguard entitlement to contributory benefits.

The Chancellor anticipates that these NIC adjustments will result in an annual saving of £450 for the average employee and £350 for the average self-employed taxpayer. It is crucial for employers and self-employed individuals to stay abreast of these changes and update financial systems accordingly.
