When Are the National Insurance Changes? Everything Employers and Employees Need to Know
National Insurance (NI) is a vital part of the UK’s tax system, funding state pensions, healthcare, and social security benefits. However, major changes to National Insurance contributions (NICs) are set to take effect from April 2025, impacting employees, employers, and the self-employed.
If you’re a business owner, payroll manager, or employee, understanding these upcoming changes is essential to avoid unexpected tax costs and optimize your financial planning.
- When are the National Insurance changes happening?
- What are the new NIC rates and thresholds?
- How will these changes impact employers, employees, and self-employed individuals?
- How businesses can prepare and reduce NIC liabilities
1. When Do the National Insurance Changes Take Effect?
The new National Insurance rates and thresholds will come into force from 6 April 2025, at the start of the 2025/26 tax year.
These changes were introduced as part of the government’s long-term plan to increase public revenue while supporting small businesses.
Key Date: 6 April 2025 – New National Insurance rates apply.
Who is affected?
Employees – Changes to Class 1 NICs.
Employers – Higher employer NIC rates and a lower threshold.
Self-Employed Individuals – Changes to Class 2 and Class 4 NICs.
2. National Insurance Changes for Employees (Class 1 NICs)
Current (2024/25) Employee NIC Rates
Employees pay Class 1 National Insurance at the following rates:
| Annual Salary | NIC Rate (2024/25) |
|---|---|
| Up to £12,570 | 0% (No NICs Paid) |
| £12,571 – £50,270 | 10% |
| Above £50,270 | 2% |
Example: If you earn £40,000 per year, you currently pay:
- 0% on the first £12,570
- 10% on £27,430 (£40,000 – £12,570) = £2,743
What Changes from April 2025?
Employee NIC rates will remain the same, but an increase in employer NICs could impact salary structures and job security.
Some businesses may adjust salaries or shift to non-salary compensation (e.g., bonuses, benefits) to offset employer costs.
3. National Insurance Changes for Employers (Class 1 Secondary NICs)
Employers pay Class 1 secondary NICs on employee wages above a certain threshold.
Current (2024/25) Employer NIC Rates
| Annual Salary | Employer NIC Rate |
|---|---|
| Up to £9,100 | 0% (No NICs Paid) |
| Above £9,100 | 13.8% |
What Changes from April 2025?
Employer NIC Rate Increases from 13.8% to 15%
Lower Employer NIC Threshold from £9,100 to £5,000
Impact:
- Employers will start paying NICs on salaries from £5,000 instead of £9,100.
- Increased payroll costs could impact hiring decisions, employee benefits, and salary adjustments.
4. Employment Allowance Increase (Good News for Small Businesses!)
To support small businesses, the Employment Allowance (which reduces employer NIC liability) will increase from £5,000 to £10,500 per year.
What This Means for Employers
More small businesses will qualify for the Employment Allowance.
Employers can offset £10,500 of their NIC liability each year.
Companies previously restricted from claiming due to high NIC liabilities will now qualify.
Example: If your business owes £9,000 in employer NICs, the new allowance would completely eliminate this cost.
5. National Insurance Changes for the Self-Employed (Class 2 & Class 4 NICs)
Current (2024/25) Self-Employed NICs
| Self-Employed Profit | Class 2 NICs | Class 4 NICs |
|---|---|---|
| Up to £12,570 | £3.45 per week | 0% |
| £12,571 – £50,270 | N/A | 10% |
| Above £50,270 | N/A | 2% |
What Changes from April 2025?
Class 2 NICs will be abolished for those with profits above £12,570.
Class 4 NICs will remain unchanged at 10% and 2% on higher profits.
The self-employed will still need to make voluntary contributions to qualify for state pensions.
6. How Businesses Can Prepare for the National Insurance Changes
The upcoming NIC increases mean that businesses must act now to prepare for rising costs.
A. Review Payroll Costs and Budgeting
Adjust cash flow projections to account for higher NICs.
Consider payroll restructuring to minimize NIC burdens.
B. Utilize the Higher Employment Allowance
Ensure your business claims the £10,500 NIC relief.
Optimize hiring strategies to stay below NIC liability thresholds.
C. Offer Tax-Efficient Employee Benefits
Salary Sacrifice Schemes: Reduce NICs by offering pension contributions, cycle-to-work schemes, and private healthcare.
D. Seek Professional Tax Planning Support
Work with an accountant to ensure NIC compliance and cost efficiency.
Identify payroll solutions that minimize employer tax burdens.
