The new pension and salary sacrifice changes, announced in the Autumn 2025 Budget,will significantly change the National Insurance treatment of workplace pension contributions from 6 April 2029.
Under the new rules, only the first £2,000 of employee pension contributions made through salary sacrifice each year will remain exempt from National Insurance contributions.
In this article, we explain what is changing, who will be affected, how the new rules will work in practice, and what steps you should consider taking now.
Pension Salary Sacrifice Changes: An Overview
Despite widespread speculation ahead of the Autumn 2025 Budget, the government chose not to introduce a cap on pension salary sacrifice contributions. Consequently, this means the Annual Allowance, currently £60,000 for most individuals, remains the main limit on tax-relieved pension savings
Instead, the New Pension and Salary Sacrifice Changes focus on tightening the rules around:
What Is Salary Sacrifice?
A Salary Sacrifice arrangement is where an employee agrees to surrender part of their gross salary in return for a non-cash benefit. In most cases today, this benefit is an employer pension contribution, as HMRC has largely restricted salary sacrifice for other types of benefits.
This method is widely used because it reduces both income tax and employee National Insurance contributions (NICs).
The pension contribution is normally made directly by the employer and is generally deductible when calculating the company's taxable profits, subject to the usual rules.
However, HMRC requires clear evidence that these arrangements are properly implemented and not used artificially. As a result, we expect increased scrutiny once the New Pension and Salary Sacrifice Changes take effect, particularly where:
We discuss directors in more detail below.
How the Pension Salary Sacrifice Changes Work from April 2029
From 6 April 2029, a new limit will apply to the National Insurance savings generated through pension salary sacrifice.
The key change
Employees will be limited to £2,000 per tax year in employee National Insurance savings arising from salary sacrifice pension arrangements.
This is not:
Once the £2,000 NIC saving limit is reached, any further sacrificed salary will become subject to Class 1 National Insurance for both the employee and the employer.
An example Employee on £60,000 salary
Let’s take John, who earns £60,000 a year and chooses to sacrifice £5,000 of his salary into his workplace pension.
Before 6 April 2029
Under the current rules, the full £5,000 salary sacrifice can generally be made free of employee and employer National Insurance, provided the salary sacrifice arrangement is valid.
From 6 April 2029
Under the new rules:
Therefore, larger pension salary sacrifice arrangements will become less National Insurance-efficient from April 2029, although salary sacrifice will continue to offer benefits.
Who Will Be Affected by the Pension Salary Sacrifice Changes?
These changes will not impact everyone equally. Those most likely to notice a difference include:
However, employees making modest contributions are unlikely to see any material change.
Do the Pension Salary Sacrifice Changes Affect Directors?
Importantly, the new £2,000 limit relates to employee pension contributions made through salary sacrifice. It should therefore be distinguished from a company making an employer pension contribution directly for a director.
For many owner-managed companies, direct employer pension contributions may continue to form part of remuneration planning without involving salary sacrifice at all. However, the normal rules governing employer pension contributions, including the Corporation Tax rules and pension annual allowance, still need to be considered.
In these situations, there may be no salary sacrifice at all, meaning the new NIC cap may not apply.
Directors are office holders rather than employees, and HMRC often views their remuneration differently. However, HMRC has not yet issued detailed guidance on how the New Pension and Salary Sacrifice Changes will apply to director-owners.
We expect HMRC to pay closer attention to:
Consequently, careful structuring and documentation remain essential.
What action should you take now?
Although the new rules do not take effect until 2029, investing in pensions is a long-term strategy. Therefore you should consider:
Pension Salary Sacrifice Changes: Key Takeaways
The New Pension and Salary Sacrifice Changes do not introduce contribution caps. Although, they do significantly change how National Insurance savings will be treated from April 2029.
For most employees making regular pension contributions, the impact will be limited. However, higher earners and businesses using salary sacrifice extensively will need to review their approach
Additionally, director-owners should continue to ensure pension contributions reflect commercial reality and are properly structured, particularly as HMRC scrutiny is likely to increase.
