Salary Sacrifice NI Relief Capped at £2,000 from 2029
The government has announced one of the most significant pension changes in recent years — and it’s aimed squarely at working professionals, higher earners and anyone who contributes more than the minimum into their pension.
From April 2029, the amount of pension contribution you can make through salary sacrifice without paying National Insurance will be capped at £2,000 per year. This is a major shift in tax policy and will reduce the efficiency of one of the most powerful long-term planning tools available to UK workers.
While you will still receive income tax relief on pension contributions, this change removes the NI advantage on contributions over £2,000 — making retirement planning more expensive for millions of responsible savers.
Below, we break down what the new rules mean, who will be affected, and the practical impact on your take-home pay.
What Is Salary Sacrifice — And Why Is It Changing?
Salary sacrifice allows you to give up part of your salary, which your employer then pays into your pension instead. Currently, this benefits you in two important ways:
-
You avoid income tax.
-
You avoid National Insurance.
-
Your employer also saves NI and often shares some of these savings with you
From 2029, that NI advantage will be limited to the first £2,000 of NI sacrificed each year.
Anything above that will still qualify for income tax relief but will now be subject to NI, removing a key financial planning advantage.
The New Rules From April 2029
Beginning 6 April 2029:
-
The first £2,000 of pension contributions made via salary sacrifice will continue to be NI-free
-
Any contributions above £2,000 will now be subject to employee and employer NI
-
The cap applies per tax year
-
You can still contribute up to your annual allowance — you just won’t get the NI benefit on the excess
This is effectively a significant tax rise on those who save more for retirement.
The New Rules From April 2029
This change will hit:
-
Mid-to-high earners contributing over £2,000/year via salary sacrifice
-
Public-sector professionals (teachers, NHS staff, civil service), although only a small amount of workers.
-
Senior employees and managers
-
Directors using salary + dividend structures
-
Anyone making meaningful additional voluntary pension contributions
Examples - Salary Sacrifice NI Relief Capped
1. Middle Earner Example: James (£50,000 salary)
Salary sacrifice: £4,000 per year
-
First £2,000 → NI-free
-
Remaining £2,000 → NI now payable
James will pay extra NI every year, reducing take-home pay and pension efficiency.
2. Higher Earner Example: Priya (£90,000 salary)
Salary sacrifice: £9,000 per year
-
First £2,000 NI-free
-
Remaining £7,000 now attracts NI
Over 10 years, Priya could lose thousands in additional NI, unless she restructures her contributions.
Could Your Employer Change Their Pension Structure?
Yes — and many likely will.
Employers currently save NI on salary sacrifice contributions. From 2029:
-
Their NI savings shrink or disappear
-
Some may reduce contributions
-
Some may stop passing NI savings back to staff
-
A small number may restructure the entire scheme
Employees should expect updated employer guidance before 2029.
What Should You Do Now?
This change makes proactive planning essential. Clients should:
✔ Review pension contributions
If you contribute more than £2,000, your NI costs will rise.
There may be better ways to structure contributions.
✔ Check employer policy
Understand how your workplace pension will treat NI savings after 2029.
✔ Rebalance your tax wrappers
ISAs, pensions, GIA and investment bonds may need re-evaluating.
✔ Protect your long-term plan
Strategic planning can retain most of the benefits salary sacrifice currently provides.
Conclusion: Smart Savers Need a Smarter Strategy
From 2029, the government is fundamentally reshaping how tax-efficient pension saving works. The new £2,000 NI relief cap will reduce the benefits for many working professionals — particularly those who save responsibly or contribute above the minimum.
While the tax system is becoming more restrictive, good advice and structured planning can still help you reduce the impact, protect your income, and build a strong retirement strategy.
