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 government has:
    - reversed  the temporary increase in NICs and
- cancelled the  Health and Social Care Levy completely.
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 took  effect for payments of earnings made on or after 6 November 2022, so:
    - primary  Class 1 NICs (employees) generally reduced from 13.25% to 12% and 3.25% to 2%  and
- secondary  Class 1 NICs (employers) reduced 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%.
NICs thresholds
A similar principle to that outlined above  for income tax thresholds will be followed in respect of the NICs upper  earnings limit and upper profits limit. From July 2022, the NICs primary  threshold and lower profits limit were increased to align with the personal  allowance and will be maintained at this level from April 2023 until April  2028. The Class 2 lower profits threshold will also be fixed from April 2023  until April 2028 to align with the lower profits limit. They will again be  £12,570 and £50,270 as appropriate.
In addition, the government will fix the  lower earnings limit and the small profits threshold at 2022/23 levels in  2023/24, namely £6,396 and £6,725 per annum respectively.
The government will uprate the Class 2 and  Class 3 NICs rates for 2023/24 to £3.45 per week and £17.45 respectively.
Finally, the government will fix the level at  which employers start to pay Class 1 NICs for their employees at £9,100 from  April 2023 until April 2028.
Comment
The government states: 'It is fair that    businesses play their part in reducing the UK's debt. The Employment    Allowance means that 40% of businesses do not pay NICs and will be unaffected    by this change, and the largest employers contribute the most.'
