A: It would be very difficult for the Government to change NIC rates for the self-employed part way through a year. The proposed reduction in Class 4 NIC for the self-employed from 9% to 8% will apply from 6 April 2024 (2024/25 tax year).
On the same date (6 April 2024) the requirement for self-employed workers to pay Class 2 NIC will be abolished. So self-employed workers will only pay Class 4 NIC on profits from tax year 2024/25 onwards.
