Introduction

Millions of UK employees stand to lose out on pension savings following a major change to the tax treatment of salary sacrifice contributions. The Chancellor, Rachel Reeves, has announced that from 2029, National Insurance will be levied on pension contributions made through salary sacrifice arrangements that exceed £2,000 per year.


New government projections indicate that this could reduce the retirement pots of higher earners, raising concerns among pension specialists about its effect on long-term saving incentives.

Overview of Pension Tax Relief Changes

The UK government has introduced a cap of £2,000 on the tax relief available for salary sacrifice pension contributions. From 2029, contributions above this threshold will be subject to National Insurance, reducing the take-home advantage of these schemes.


This measure was detailed by the Chancellor during the recent Budget announcement. The move aims to generate additional revenue by reducing one of the current tax efficiencies used by employees and employers to boost pension savings.


Government figures show that more than three million workers could be affected by this policy alteration.

Impact on High Earners and Pension Savings

Industry analysis suggests that individuals on higher incomes stand to lose substantial sums in their final pension pots under the new rules. According to calculations by investment firm AJ Bell, a 35-year-old earning £50,000 annually could see their retirement fund reduced by £22,000, while someone on a £100,000 salary might lose nearly £50,000 if they adjust their contributions in response to the new charges.


These figures reflect anticipated changes in saving behaviours, with affected individuals likely to reduce pension contributions given the diminished tax relief.

Understanding Salary Sacrifice Arrangements

Salary sacrifice is a voluntary arrangement where employees opt to reduce their gross salary in exchange for non-cash benefits, most commonly pension contributions. In its current form, this mechanism allows employees and employers to save on both National Insurance and income tax, making pension saving more attractive for many workers.


The government estimates that around 7.7 million employees use salary sacrifice for pension saving. Of these, Treasury analysis indicates approximately 44 per cent contribute over £2,000 per year through this method and would be directly impacted by the cap.

Effects on Take-Home Pay and Retirement Savings

With the introduction of National Insurance on higher salary sacrifice contributions, there is concern that take-home pay and incentive to save for retirement could be negatively affected. Pension pot projections are expected to be lower for a significant portion of higher and middle earners as a result of the change.


Government reports have also revealed a broader challenge, with British workers already on course to be around 8 per cent poorer in retirement compared with today’s pensioners, and nearly half under-saving against recommended targets.

Industry Reactions to New Policy

Former Pensions Minister Baroness Ros Altmann described the policy as “another nail in the coffin” for workplace pension schemes, warning that it may discourage saving and prompt some individuals to abandon their pension plans altogether.


“There is no way that this measure can improve pensions. It can only make them worse,” she said. Tom Selby, of financial services provider AJ Bell, commented that workers were being “punished for doing the right thing” by contributing to pensions, according to reports.

Final Summary

The upcoming cap on salary sacrifice pension tax relief will have a pronounced impact on high and middle-income earners, reducing the potential gains from pension saving through this method. While the government aims to enhance tax system fairness and secure additional revenue, critics warn of the potential for decreased pension participation and smaller retirement funds.


The development forms part of a broader context in which households are already facing challenges to maintain adequate retirement savings.
