Budget 2025: New £2,000 Salary Sacrifice Pension Cap — Full UK Guide
Budget 2025: New £2,000 Salary Sacrifice Pension Cap
From 6 April 2029, salary sacrifice pension contributions above £2,000 per employee per year will be subject to employer and employee National Insurance Contributions (NICs). This ends the unlimited NICs relief previously available.
1. What Is Salary Sacrifice and What Has Changed?
How Salary Sacrifice Currently Works (Until April 2029)
Salary sacrifice is an arrangement where an employee agrees to reduce their gross salary in exchange for a non-cash benefit — in this case, employer pension contributions. Both the employee and employer currently save on NICs for the entire sacrificed amount.
Current System (2025-2029):
- Employee reduces gross salary by any amount
- Employer contributes equivalent amount to pension
- No NICs paid on the entire sacrificed amount by either party
- Full income tax relief still applies on pension contributions
- Particularly beneficial for high earners and those receiving bonuses
The New Rules From April 2029
Chancellor Rachel Reeves announced in Budget 2025 that salary sacrifice for pension contributions will be capped at £2,000 per employee annually for NICs relief purposes.
New System (From 6 April 2029):
- First £2,000 of salary sacrifice: No NICs paid (as now)
- Amounts above £2,000: Both employer and employee NICs apply as if it were regular salary
- Income tax relief on pension contributions remains unchanged (still available in full)
- The cap is per employee, per tax year
2. Who Is Most Affected by the £2,000 Cap?
High-Impact Groups
This change particularly affects:
- High Earners Using Bonus Sacrifice
- Financial services professionals (bankers, traders, fund managers)
- Senior executives receiving large annual bonuses
- Anyone sacrificing more than £2,000 annually
- Company Directors & Owner-Managers
- Those taking minimal salary and maximising pension contributions
- Directors using profits for pension funding via salary sacrifice
- Small business owners optimising remuneration packages
- Professional Partnerships
- Law firms, accountancy practices, consultancies
- Partners using salary sacrifice for significant pension funding
- Employees in Flexible Benefit Schemes
- Large corporate employers offering comprehensive flex schemes
- Public sector workers with generous pension matching arrangements
Who Is Protected?
The government designed the cap to shield lower and middle earners:
- 74% of basic rate taxpayers currently using salary sacrifice will be unaffected
- Workers contributing up to £2,000 annually maintain full NICs relief
- Auto-enrolment pension schemes typically won't exceed the threshold
3. Financial Impact: What It Means for Taxpayers
Example 1: £10,000 Bonus Sacrifice
Consider a higher-rate taxpayer (earning £60,000) receiving a £10,000 bonus and choosing to sacrifice it entirely into their pension.
Current System (2025-2029)
| Component | Amount |
|---|---|
| Gross bonus | £10,000 |
| Employee NICs saved (13.8%) | £0 (sacrificed) |
| Employer NICs saved (15%) | £1,500 saved |
| Income tax (40%) | £0 (pension contribution) |
| Net pension contribution | £10,000 |
| Employer potentially adds savings | £11,500 |
New System (From April 2029)
| Component | Amount |
|---|---|
| First £2,000 sacrifice | £2,000 (full NICs relief) |
| Remaining £8,000 | £8,000 (NICs now apply) |
| Employee NICs payable (13.8%) | -£1,104 |
| Employer NICs payable (15%) | -£1,200 |
| Income tax relief (40%) | Still £0 (full relief applies) |
| Net pension contribution | £10,000 |
| Total NICs cost (both parties) | £2,304 |
Additional Cost: £2,304 in NICs that wouldn't have been payable under the old system.
Example 2: Company Director Contributing 30% of Income
A director earning £80,000 who contributes £24,000 annually (30% of salary) via salary sacrifice.
| Item | Before April 2029 | After April 2029 |
|---|---|---|
| Total pension contribution | £24,000 | £24,000 |
| Amount with NICs relief | £24,000 | £2,000 |
| Amount subject to NICs | £0 | £22,000 |
| Employee NICs (13.8%) | £0 | £3,036 |
| Employer NICs (15%) | £0 | £3,300 |
| Total additional cost | - | £6,336 per year |
For higher earners making substantial pension contributions, the loss of unlimited NICs relief represents a significant increase in the effective cost of pension funding. However, income tax relief remains fully available, meaning pension contributions still benefit from 40% or 45% tax relief for higher and additional rate taxpayers.
4. Strategic Alternatives & Tax Planning Options
Option 1: Employer Direct Contributions (Outside Salary Sacrifice)
Employer pension contributions made directly (not via salary sacrifice) remain free from NICs entirely, with no £2,000 cap.
How This Works:
- Employer makes pension contribution as a business expense
- No reduction to employee's contractual salary
- Employer gets Corporation Tax relief on the contribution
- No NICs for employer or employee, regardless of amount
- Employee still receives full income tax relief on the contribution
Ideal for: Company directors, business owners, and high earners employed by their own limited companies.
Option 2: Bonus Restructuring
Instead of sacrificing bonuses, structure remuneration differently:
- Direct employer contribution of bonus amount — avoids NICs entirely
- Split large one-off payments — use first £2,000 via salary sacrifice, remainder as direct employer contribution
- Multi-year planning — spread contributions across tax years to maximise the £2,000 annual allowance
Option 3: Dividend and Profit Extraction Planning (Directors)
Company directors may consider:
- Increasing employer pension contributions instead of taking dividends
- Using retained profits to fund pensions directly (Corporation Tax deductible, no NICs)
- Balancing salary, dividends, and pensions to optimise overall tax efficiency
Example: Director Remuneration Strategy Post-2029
Scenario: Director of profitable limited company, age 45, wants to extract £100,000 from the business.
| Extraction Method | Tax/NICs Cost | Net Received / Pension Value |
|---|---|---|
| All as salary | ~£38,000 | ~£62,000 net |
| Salary + dividends (£12,570 + £87,430) | ~£28,000 | ~£72,000 net |
| Employer pension contribution (£100k) | £0 NICs, £25,000 CT relief | £100,000 in pension |
| Salary £50k + Pension £50k (direct) | ~£15,000 (salary only) | £35k net + £50k pension |
Conclusion: Direct employer contributions remain the most tax-efficient method for funding retirement, even after the salary sacrifice cap is introduced.
Option 4: Lifetime Allowance Considerations
With the abolition of the Lifetime Allowance in April 2024, larger pension contributions can now be made without the previous £1.073 million cap. This makes direct employer contributions even more attractive for wealth accumulation.
Annual Allowance Reminder:
- Standard Annual Allowance: £60,000 per tax year
- Tapered for those earning over £260,000 (minimum £10,000)
- Carry forward available for unused allowances from previous 3 years
- Contributions above the allowance incur tax charges
5. Employer Implications & Action Plan
Impact on Workplace Pension Schemes
Employers offering salary sacrifice pension schemes should:
- Review Current Arrangements
- Identify employees sacrificing more than £2,000 annually
- Calculate the additional NICs cost from April 2029
- Model the impact on both employer and employee costs
- Consider Scheme Redesign
- Offer direct employer contributions alongside or instead of salary sacrifice
- Introduce tiered contribution structures
- Maintain salary sacrifice for amounts up to £2,000, direct contributions for excess
- Communicate Changes
- Begin employee education well before April 2029
- Provide individual impact assessments
- Offer one-to-one financial guidance where appropriate
- Update Payroll Systems

6. What About Other Salary Sacrifice Benefits?
The £2,000 cap applies only to pension contributions. Other salary sacrifice arrangements remain unaffected:
- ✅ Cycle to Work schemes — unlimited NICs relief continues
- ✅ Electric vehicle salary sacrifice — no NICs cap
- ✅ Childcare vouchers (existing schemes) — unchanged
- ✅ Ultra-low emission company cars — exempt from NICs as now
- ✅ Technology schemes (laptops, phones) — no change
Why Only Pensions?
The government identified pension salary sacrifice as disproportionately benefiting higher earners, with costs forecast to rise from £2.8 billion (2016-17) to £8 billion (2030-31) without reform. The £2,000 cap aims to protect lower earners whilst controlling the cost to the Exchequer.
7. Transitional Arrangements & Implementation Date
Key Dates
- 26 November 2025: Budget 2025 announcement
- Finance Bill 2025-26: Legislation introduced to Parliament
- 6 April 2029: New £2,000 cap takes effect
No Grandfathering
Unlike some previous pension changes, there will be no protection for existing arrangements. All salary sacrifice pension contributions above £2,000 per employee per year will be subject to NICs from 6 April 2029, regardless of when the arrangement was set up.
Annual Basis
The £2,000 threshold operates on a tax year basis (6 April to 5 April). It cannot be averaged over multiple years or carried forward.

8. Frequently Asked Questions
Q1: Can I still contribute more than £2,000 to my pension via salary sacrifice?
A: Yes, but you'll pay NICs on the amount above £2,000. Income tax relief remains fully available on the entire contribution.
Q2: Does the £2,000 cap apply per employment or per person?
A: It's per employee, per employer, per tax year. If you have multiple employments, you can use salary sacrifice up to £2,000 with each employer without NICs.
Q3: What if I make a large one-off contribution via salary sacrifice?
A: Only the first £2,000 in that tax year will be exempt from NICs. The remainder will be subject to employer and employee NICs as normal. Consider using a direct employer contribution instead.
Q4: Are employer contributions made directly (not via salary sacrifice) affected?
A: No. Direct employer pension contributions remain entirely free from NICs, with no limit. This is often the better option for large contributions post-2029.
Q5: I'm a company director — what's my best strategy?
A: For directors of limited companies, making direct employer pension contributions (not salary sacrifice) remains the most tax-efficient approach. These attract Corporation Tax relief, avoid NICs entirely, and aren't subject to the £2,000 cap.
Q6: Does this affect auto-enrolment pensions?
A: Most auto-enrolment schemes won't be impacted, as typical contributions (minimum 8% of qualifying earnings) rarely exceed £2,000 annually for average earners. Higher earners making additional voluntary contributions may be affected.
Q7: Can I spread contributions across tax years to stay under the cap each year?
A: Yes, but this may not be optimal. Instead, consider using direct employer contributions for amounts above £2,000 in any given year.
Q8: What happens if I change jobs mid-year?
A: The £2,000 allowance is per employer. If you move jobs partway through a tax year, you can potentially benefit from £2,000 of NICs-free salary sacrifice with each employer (pro-rated if needed).
