In September 2021 the government published its proposals for new  investment in health and social care in England. The proposals were intended to  lead to a permanent increase in spending not only in England but also by the  devolved governments. To fund the investment the government introduced a  UK-wide 1.25% Health and Social Care Levy based on the National Insurance  contributions (NICs) system but ringfenced for health and social care.
The Health and Social Care Levy Act provided for a temporary 1.25%  increase to both the main and additional rates of Class 1, Class 1A, Class 1B  and Class 4 NICs for 2022/23. From April 2023 onwards, the NIC rates were  intended to revert back to 2021/22 levels and be replaced by a new 1.25% Health  and Social Care Levy.
However, the new Chancellor has decided to:
    - reverse  the temporary increase in NICs from November and
- cancel the  Health and Social Care Levy completely.
The Health and Social Care Levy was expected to raise around £13  billion a year to fund health and social care and the Chancellor has confirmed  that funding will be maintained at the same level as if the Levy was in place,  funded from general taxation.
Comment
According to the government, not proceeding with the Levy will    reduce tax for 920,000 businesses by nearly £10,000 on average next year.
For SMEs, the government predicts that the savings will be around    £4,200 on average for small businesses and £21,700 for medium sized firms    from 2023/24.
In addition, it will help almost 28 million people across the UK    save £330 on average in 2023/24, with an additional saving of around £135 on    average this year.
More detail for  employees and employers
The  changes take effect for payments of earnings made on or after 6 November 2022,  so:
    - primary  Class 1 NICs (employees) will generally reduce from 13.25% to 12% and 3.25% to  2% and
- secondary  Class 1 NICs (employers) will reduce from 15.05% to 13.8%.
The  effect on Class 1A (payable by employers on taxable benefits in kind) and Class  1B (payable by employers on PAYE Settlement Agreements) NICs will effectively  be averaged over the 2022/23 tax year, so that the rate will generally be  14.53%.
Comment
The government hopes that most employees will receive the NICs    reduction directly via the payroll in their November pay but acknowledges    that some will have to wait until December or January, depending on the    complexity of their employer's payroll software.
More detail for the  self-employed
Following  the principle detailed above, the changes to Class 4 NICs will again be  averaged across 2022/23, so that the rates will be 9.73% and 2.73%.
