Starting from 6th April 2025, significant changes to the UK’s National Insurance Contributions (NICs) will come into effect, impacting employers nationwide. It’s essential for businesses to understand these modifications to plan accordingly.
Increase in Employer NIC Rate
The rate of employer NICs will rise from the current 13.8% to 15%. This increase means that for every employee earning above the Secondary Threshold, employers will contribute a higher percentage of their earnings to NICs.

Reduction in Secondary Threshold
The Secondary Threshold—the earnings level at which employers begin paying NICs—will decrease from £9,100 to £5,000 per annum. Consequently, employers will start contributing NICs on employee earnings exceeding £5,000, broadening the scope of NIC liabilities.
Enhancement of Employment Allowance
Additionally, to mitigate the impact on smaller businesses, the Employment Allowance will increase from £5,000 to £10,500 annually. Furthermore, the previous restriction preventing employers with NIC liabilities exceeding £100,000 in the prior tax year from claiming this allowance will be removed. This change allows a broader range of businesses to benefit from reduced NIC liabilities.

Understanding the Employment Allowance
The Employment Allowance is a relief that enables eligible employers to reduce their annual NIC bill by a specified amount. With the upcoming increase to £10,500, businesses can offset a more substantial portion of their NIC liabilities, easing the financial burden associated with employing staff.
Financial Impact on Businesses: Examples
Consider the following scenarios to illustrate the financial implications:
Example: Small & Medium-Sized Business Employer NIC costs
- Current Scenario (2024-25):
- Employee Salary: £36,000 per annum
- NIC Payable: 13.8% on earnings above £9,100
- NIC Calculation: £36,000 – £9,100 = £26,900
- NIC Due: £26,900 x 13.8% = £3,712.20
- Future Scenario (2025-26):
- Employee Salary: £36,000 per annum
- NIC Payable: 15% on earnings above £5,000
- NIC Calculation: £36,000 – £5,000 = £31,000
- NIC Due: £31,000 x 15% = £4,650
- Additional Annual Cost per Employee: £4,650 – £3,712.20 = £937.80
Example: Small Business Utilising Employment Allowance
- Annual NIC Liability Before Allowance: £8,000
- Current Employment Allowance: £5,000
- NIC Payable After Allowance (2024-25): £8,000 – £5,000 = £3,000
- Future Employment Allowance (2025-26): £10,500
- NIC Payable After Allowance: £8,000 – £10,500 = £0 (with £2,500 allowance remaining)
- Impact: The increased Employment Allowance not only covers the entire NIC liability but also leaves an unused allowance, providing significant relief to small businesses.
