The increase in employer National Insurance contributions (NICs) from 13.8% to 15% will have a big impact on contractors across the UK. This 1.2 percentage points rise, starting from 6 April 2025, is one of the biggest tax changes in recent years and will affect different types of contractor setups in different ways. Whether you work through a limited company, an umbrella company, or an agency, this change may put extra financial pressure on you.

What Changes to National Insurance Did the Chancellor Announce?
In the October 2024 Autumn Budget, Chancellor Rachel Reeves announced some important changes to National Insurance (NI) that mainly affect employers and contractors:
- The main rate of employer NICs will go up from 13.8% to 15% from 6 April 2025.
- The Employment Allowance for eligible small businesses will increase from £5,000 to £10,500.
- The secondary threshold (when employers start paying NICs) will decrease from £9,100 per year to £5,000 per year.
- The restriction preventing businesses with payroll costs over £100,000 from claiming the allowance will be removed starting April 2025. All eligible employers can now claim up to £10,500 regardless of payroll size.
- No changes to Class 1 employee NICs or Class 2 and Class 4 NICs for self-employed workers.
These measures are expected to raise substantial revenue – up to £23.7 billion annually by the 2025/26 tax year – to fund public services like the NHS.
Additional Changes Affecting Employers
As part of the upcoming changes, several other adjustments will impact employers starting in April 2025. These changes may introduce additional costs and considerations for businesses:
- National Minimum Wage Increase – Starting in April 2025, the National Minimum Wage will increase to £12.21 per hour. This can put extra financial pressure on businesses that employ staff.
- Class 1A and Class 1B NICs – The rates for Class 1A and Class 1B National Insurance contributions will also rise in line with the increase in secondary Class 1 NICs.
- Veterans’ NIC Relief – Employers who hire veterans will continue to benefit from relief on employer NICs during the first year of their civilian employment.
How Will the National Insurance Increase Affect Different Contractor Structures?
The rise in NI will affect contractors differently depending on how they work. We’ve provided a simple breakdown:
Limited Company Contractors
If you run your own limited company, the NIC increase will apply when you pay yourself (or any employees) a salary over £5,000 per year (down from £9,100). Your company will now pay 15% instead of 13.8% on anything above that amount.
For example:
| Annual Salary | Current NICs (13.8%) | New NICs (15%) | Additional Annual Cost |
| £20,000 | £1,504 | £1,635 | £131 |
| £30,000 | £2,884 | £3,135 | £251 |
| £50,000 | £5,644 | £6,135 | £491 |
| £100,000 | £12,544 | £13,635 | £1,091 |
Umbrella Company Contractors
If you work through an umbrella company, you’ll probably feel the increase more. Umbrella companies often have tight margins and may pass the extra costs on to contractors. This could mean higher fees from your umbrella company, lower take-home pay, and lower assignment rates as umbrella companies negotiate with agencies.
Most umbrella companies use PAYE, so they’ll pay the full 1.2 percentage points increase on all salaries above the £5,000 threshold.
Recruitment Agencies and End Clients
Agencies and clients who directly hire contractors will also feel the increase’s ripple effect. They may face higher costs for hiring temporary workers, pressure on profit margins, lower contractor rates to balance costs, and clients paying more to bring contractors onto their payroll.
What Strategies Can Contractors Use to Mitigate the NIC Increase?
Contractors can explore several approaches to minimise the impact of these changes:
- Salary and Dividend Planning – Limited company contractors may want to review their remuneration strategy, potentially adjusting the balance between salary and dividends
- Pension Contributions – Employer pension contributions are exempt from NICs. This makes them an increasingly valuable way to extract value from your company
- Salary Sacrifice Arrangements – These can reduce the amount of salary subject to NICs while providing benefits to employees
- Review Contracts and Rates – Consider negotiating higher rates with clients to offset the increased costs
- Maximise Allowable Expenses – Ensure you claim all legitimate business expenses to reduce your overall tax burden
Are There Any Opportunities Within These Changes?
Even though the NIC increase is challenging, there may be some opportunities for contractors:
Competitive Edge for Some Businesses
If your company’s payroll costs are under £100,000, you can still use the full Employment Allowance. This could give you an advantage over larger businesses.
Shift to Value-Based Pricing
Instead of charging by the day, some contractors might switch to pricing based on the results they deliver. This focuses on the value of the work, not just the time spent.
Insurance Becomes More Important
With tighter margins, having the right insurance (like professional indemnity) is even more important to protect your business from unexpected costs.
How Can Professional Saver Help Contractors Navigate These Changes?
While we can’t eliminate the impact of NIC increases, Professional Saver offers insurance solutions that can help protect your business during this period of financial adjustment:
- Professional Indemnity Insurance – Starting from £54 per year, this essential cover protects you against claims of professional negligence or mistakes.
- Public Liability Insurance – Protects against claims of property damage or injury to third parties.
- Financial Loss Cover – Safeguards against claims for pure financial loss caused to clients.
For contractors facing tightening margins due to the NIC increase, having the right insurance at competitive rates becomes even more crucial. Our policies can be tailored to your specific trade and requirements, ensuring you’re not paying for cover you don’t need.
What Should Contractors Do Before April 2025?
Before the NIC increase takes effect, contractors should:
- Calculate exactly how the changes will affect your business financially.
- Speak with your accountant about optimising your tax structure.
- Review your contracts and consider rate negotiations with clients.
- Evaluate your insurance coverage to ensure it’s comprehensive and cost-effective.
- Consider joining contractor forums or professional bodies for collective support.
Planning Ahead to Stay Competitive
The rise in employer NI is a big challenge for contractors across the UK. But if you understand how it affects your business and plan ahead, you can reduce the impact and stay competitive.
Even though higher taxes can squeeze your profits, cutting back on insurance isn’t the answer. In fact, having the right insurance is even more important when times are tough.
