The extra costs of the increase in employers' NICs  could cause businesses to respond in ways the government did not intend, the  Chartered Institute of Taxation (CIOT) has warned.
At the Autumn Budget, Chancellor Rachel Reeves  announced an increase to the rate of employer NICs by 1.2 percentage points, to  15% from 6 April 2025.
The CIOT says that the increase extends the  differential in the burden of tax and NICs borne by those in employment  compared to those engaged as self-employed.
The higher employers' NICs goes, the greater the  likelihood employers may seek ways to mitigate or absorb the burden, which  could include potential alternative arrangements to taking on people as  employees, adds the CIOT. Alternatives could include outsourcing or offshoring  services and reducing the numbers of employees.
Eleanor Meredith, Chair of CIOT's Employment Taxes  Committee, said:
'While employers must pay  employer NICs on their employees' earnings, no employer NICs is due where  someone is genuinely self-employed. 
'We are concerned that the  increase in employers' NICs could lead to an increase in 'false  self-employment', where businesses trying to save money turn to arrangements  where the worker is not directly employed by them, without necessarily  appreciating the rules and risks of such arrangements. 
'A worker's employment  status for tax is notoriously difficult to judge, as we have seen from recent  complex litigation involving some TV presenters. HMRC will need to be  sufficiently resourced to tackle potential increases in 'false  self-employment'.'
