From 6 April 2029, HMRC will introduce a £2,000 annual cap on the amount of pension contributions made via salary sacrifice that are exempt from National Insurance contributions (NICs). Amounts above this limit will be subject to both employee and employer NICs, though income tax relief remains.
Key Details Regarding the Cap:
Effective Date: 6 April 2029.
Limit: The first £2,000 of employee pension contributions via salary sacrifice per tax year remains NI-free.
Impact: Over 3 million employees who currently sacrifice more than £2,000 are expected to be affected.
Employer Impact:
Employers will be required to calculate and pay Class 1 NICs on any amounts exceeding the £2,000 limit.
Context: This change aims to curb the rising cost of tax-free salary sacrifice arrangements, which has increased from £2.8 billion to £5.8 billion in NICs from 2016 to 2024.
Current Rules (Before April 2029):
Currently, there is no specific monetary limit on salary sacrifice for pensions, provided the employee's salary does not drop below the National Minimum Wage or National Living Wage.
Other Salary Sacrifice Schemes:
While pension, childcare, and cycle-to-work schemes are commonly supported, most other forms of salary sacrifice (e.g., cars, gym memberships) were removed from tax advantages in 2017.
The £2,000 cap starting on 6 April 2029 could disincentivise retirement saving at a time when many people are already facing a "retirement crisis".
While the government argues this change makes the system "fairer" by targeting relief that disproportionately benefits higher earners, critics have highlighted several significant drawbacks:
Impact on Employees
Reduced Take-Home Pay: Roughly 3.3 million workers currently sacrifice more than £2,000 annually and will see their take-home pay decrease due to new National Insurance (NI) charges.
Disproportionate Hit to Lower/Middle Earners: Because of how NI rates work, those earning below £50,270 may pay 8% NI on contributions above the cap, while higher earners only pay 2% on the excess.
Long-Term Savings Gap: Analysis suggests a 35-year-old earning £50,000 could see their final pension pot reduced by over £22,000 by age 65 as a result of these lost NI savings.
Impact on Employers
Rising Costs: Businesses will face a 15% NI charge on any employee contributions over the £2,000 limit, significantly increasing payroll costs.
Reduction in Benefits: Some employers may respond by reducing their own pension contributions or scaling back other employee benefits to offset the new tax bill.
Administrative Burden: Approximately 290,000 employers will need to update software and training to manage the complex new calculations for each employee.
What Remains Beneficial
Despite the cap, pension saving remains highly tax-efficient. Full income tax relief still applies to all contributions, and salary sacrifice continues to be a primary tool for lowering "adjusted net income" to avoid the 60% tax trap or keep eligibility for Tax-Free Childcare and Child Benefit.
