Introduction
Big changes are coming to the National Insurance system in April 2025, and they will have a direct impact on businesses across Scotland. The UK Government has announced a rise in employer National Insurance Contributions (NICs), a reduction in the earnings threshold at which employers start paying, and an increase in the Employment Allowance. These changes will significantly alter how businesses manage their payroll costs. Some firms will see higher tax bills, while others—particularly smaller businesses—might actually end up better off.
So, what does this mean for employers? And how can businesses prepare? Let’s break it down in plain terms.
The Key National Insurance Changes
From 6 April 2025, three key changes will take effect:
- Employer NICs Rate Increase: The rate of employer NICs is rising from 13.8% to 15%.
- Lower Earnings Threshold: Employers will now pay NICs on earnings above £5,000 per year, rather than the current £9,100.
- Employment Allowance Increase: The Employment Allowance, which helps small businesses reduce their NIC bills, will increase from £5,000 to £10,500.
While the first two changes will push up costs for employers, the expanded allowance means many smaller firms will actually pay less National Insurance overall. But to understand this better, let’s look at a practical example.
Case Study: A Small Business with Five Employees
Let’s take the example of a small Scottish business that employs five staff members, all aged 30, working 35 hours per week at minimum wage. From April 2025, the National Living Wage will be £12.21 per hour, meaning each worker earns £22,207 per year.
Before the Changes (2024/25 Tax Year)
- Employers currently pay NICs at 13.8% on any earnings above £9,100 per year.
- For each worker, NIC is due on £13,107 of their earnings.
- That results in £1,809 in employer NICs per employee.
- With five employees, total NICs come to £9,045 per year.
- After applying the £5,000 Employment Allowance, the employer’s net NIC bill is £4,045 per year.
After the Changes (2025/26 Tax Year)
- NICs will now apply to earnings above £5,000 per year.
- That means employers must pay NICs on £17,207 per employee.
- With the new rate of 15%, this results in £2,581 in NICs per employee.
- Across five employees, total NICs rise to £12,905 per year.
- However, with the Employment Allowance increasing to £10,500, the net NIC bill drops to £2,405 per year.
What This Means for the Employer
Despite the increase in NIC rates and the lowered threshold, this small business actually pays less National Insurance under the new system. The increased Employment Allowance more than offsets the additional costs, leading to a tax saving of £1,640 per year.
Impact on Different Types of Employers
- Small businesses (low NIC bills): If your NIC liability is under £10,500 per year, you could see little to no increase or even a reduction in what you pay, thanks to the Employment Allowance.
- Medium-sized businesses (moderate NIC bills): Firms that exceed the £10,500 allowance but have relatively modest payrolls will pay more NIC overall.
- Larger employers (high NIC bills): For businesses that employ many staff or have high wages, the NIC increase will be significant. The extra allowance will make only a small dent in their overall tax bill.
Wider Economic Implications
For sectors with tight margins—such as hospitality, retail, and care services—the rise in NIC costs could put additional pressure on employers. Some businesses may respond by reducing staff hours, hiring fewer workers, or increasing prices to offset higher payroll costs. However, for smaller employers who qualify for the increased allowance, the tax relief will help cushion the impact.
What Employers Should Do Next
- Check Your Payroll Costs: Use payroll software or consult an accountant to work out how these changes will affect your business.
- Plan for Wage Increases: The National Living Wage is also rising in April 2025, so factor that into your payroll budget.
- Claim the Employment Allowance: Ensure your business applies for this automatically through HMRC.
- Consider Adjustments: If your NIC bill is rising, look at ways to manage costs, such as adjusting working patterns or reviewing hiring plans.
Conclusion
The National Insurance changes coming in April 2025 will have a mixed impact on Scottish businesses. While larger employers will face increased costs, smaller firms may actually benefit from the boosted Employment Allowance. Understanding how these changes affect your business now will help you plan ahead and avoid any surprises come the new tax year.
For those running small businesses, the good news is that, despite initial concerns, these tax changes could work in your favour. But for larger firms, it’s time to prepare for higher payroll costs in the years ahead.
