This cap throws a spanner into the works of private sector pensions, where salary sacrifice is a crucial and valued feature of workplace schemes. At £4.7 billion, the tax take is greater than expected and means the impact of this policy on pensions, pay or businesses – or all three – could be severe.
Restricting salary sacrifice is a tax penalty on people trying to the right thing by saving efficiently for their own retirement and it’s yet another National Insurance cost increase imposed on firms, which may result in reduced pay and pension benefits for private sector employees. Some employers who currently pay more than the auto-enrolment minimum on behalf of their employees will be inclined to reduce their contribution rates or other employee benefits to adjust for these changes.
Under the current minimum auto-enrolment scheme percentage contribution rates, someone earning less than £40,000 a year will not be affected by these changes. For those who earn more, it will depend on how firms react and how they manage their pension systems. It could be that many white-collar workers will just see their monthly NI bill go up and take-home pay go down if they study their payslip.
But one thing this salary sacrifice crackdown won’t do is earn the Chancellor a backlash from the public sector, as a raid on tax-free cash would have done. It is politically convenient that public sector schemes do not generally operate on a salary sacrifice basis but rather operate as ‘net pay arrangements’.
A cap on employee salary sacrifice for pension contributions should therefore have little impact on the public sector, including all of the civil service and government-backed schemes, which will save this Government another run-in with the unions and vested public sector interests.
However, the upshot is that it will put a further wedge in the growing divide between private and public sector pensions. Restricting this sensible tax benefit that makes private sector saving more attractive adds insult to injury in a two-tier pension system where public sector pensions, underwritten by taxpayers, are hugely more generous and reliable than those available in the private sector.
