As the 2025-2026 tax year approaches, UK small and medium-sized businesses (SMBs) are facing some big changes. From higher National Insurance (NI) contributions for employers to rises in the National Minimum Wage (NMW) and National Living Wage (NLW), these updates are set to impact payroll and operational costs.

In this article, we've outlined the key changes coming your way and shared some strategies to help your business stay on top.

1. Employer National Insurance Contributions Increase

What’s Changing?
Starting in April 2025, employers will need to pay 15% National Insurance on salaries above £5,000, up from the current rate of 13.8%. This increase will directly impact payroll costs, particularly those businesses with larger teams or higher-paid employees.

How Will This Affect SMBs?
For SMBs, who often run on tighter budgets, this could be a big hit. The extra costs will depend on the size of your team and the pay structure, but it’s really important to plan ahead for these increases.

2. Changes to Employment Allowance

What’s Changing?
The Employment Allowance, which helps businesses reduce their National Insurance contributions, will be adjusted in April 2025. Employment Allowance will increase to £10,500 per year from 6th April 2025. The £100,000 eligibility threshold (the cap where employers are not eligible for the employment allowance if the amount of employers NIC they pay exceeds £100,000 in the previous year) is being removed. These changes aim to make it easier for more businesses to access the allowance and will be particularly helpful for smaller businesses to avoid the worst impacts of the NI increase.

How Will This Affect SMBs?
If you're running a smaller business, these changes could be a lifeline, which will help offset some of the financial pressures from the rising National Insurance rates.

3. National Minimum Wage (NMW) & National Living Wage (NLW) Increases

What’s Changing?
In April 2025, both the National Minimum Wage for younger workers and the National Living Wage for those aged 23 and over will rise. These increases will push up salary costs for businesses with entry-level or minimum-wage employees, particularly in industries like retail, hospitality, and social care.

How Will This Affect SMBs?
The pay baseline for employees is getting higher, which means businesses in low-wage sectors will face increased salary bills. This could be tough for SMBs trying to manage tight payroll budgets.
