1. What Are National Insurance Contributions (NICs) ?

National Insurance Contributions (NICs) are mandatory payroll taxes that fund the UK’s welfare system. The NICs support public services like the state pension, the National Health Service (NHS), unemployment benefits, and parental leave.

Who Pays NICs and What Are the Classes?

Both employees, employers, and self-employed individuals are required to contribute to the NICs system. Contributions vary depending on the employment status, and they are classified by different NIC categories:

• Class 1 (Employee): Paid by employees through deductions from their salary on earnings above the Primary Threshold.
  
  
• Class 1 (Employer): Paid by employers on top of wages paid, for earnings above the Secondary Threshold.
  
  
• Class 2 and Class 4 (Self-employed):
  • Class 2 is typically a flat weekly rate, applicable when annual profits exceed a set threshold.
  • Class 4 is a percentage of annual profits, paid once earnings exceed a specified amount.

To explore the full list of NICs thresholds, rates, and additional classifications, visit the official GOV.UK website for the latest updates. Meanwhile, Slasify has a complete guide for UK employment to help you get started on what needs to be done before making a first hire in the UK. 

Why NICs Matter to Employers?

Staying on top of employer National Insurance Contributions is more than a compliance task, as NICs are a mechanism to fund essential safety net programs. For employers, NICs can also affect recurring payroll costs that significantly impact budgeting and staffing decisions. 

NICs vs Income Tax and International Comparisons

NICs are different from income tax because they fund specific benefits like pensions and healthcare, rather than going into the UK's general budget. Many other countries have similar systems, like the Social Security Contributions in the U.S., but the structure, rates, and thresholds vary widely.

2. Key Changes to Employer National Insurance Contributions in 2026

The changes that took effect on April 6, 2025, are now the strict baseline for companies executing their 2026 payroll planning. The UK government introduced four key adjustments:

• The Class 1 secondary NICs rate (your primary employer contribution) increased from 13.8% to 15%.

• The Secondary Threshold was lowered from £9,100 to £5,000 per year.

• The Employment Allowance was raised from £5,000 to £10,500.

• The £100,000 eligibility cap for the Employment Allowance was completely removed.

These adjustments align with the UK’s Autumn Budget 2024, focusing on boosting national revenue and providing targeted relief for smaller enterprises. 

These updates to employer NI rates also represent one of the most significant increases in recent years, and the lower threshold means a larger portion of employee earnings will now be subject to NICs.

What to Expect in the 2026/2027 Tax Year

While the heavy-hitting 15% employer rate and the £5,000 secondary threshold remain strictly in place for 2026, employers must adjust their payroll systems for several new April 2026 updates:

• National Living Wage Increase: The minimum wage for workers aged 21 and over rises to £12.71 per hour, amplifying the overall payroll burden when combined with the 15% NIC rate.
  
  
• Lower Earnings Limit (LEL) Adjustment: The LEL increases to £6,708 per year ( £129 per week), slightly altering the threshold at which employees build entitlement to state benefits.
  
  
• New NIC Exemptions for Reimbursements: In a welcome move for employee benefits, from April 2026, employers can reimburse staff for home working equipment, eye tests, and flu vaccinations completely free of Tax and National Insurance liabilities.

3. Implications for Your Business

Employers need to consider how higher employer NI rates and shifting thresholds affect different parts of their business. From budgeting and compensation to workforce structure and commuNICsations, the ripple effects are real. Here are some of the challenges that businesses may face:

Rising Employer Costs

At first glance, the rate hike (from 13.8% to 15%) might not sound drastic, but the impact of these updated employer ni rates grows quickly when scaled across your workforce. Here are concrete examples to illustrate the impact:

• A 10-person team with £35,000 salaries costs the business around £4,200 more annually.
  
  
• A high earner making £70,000 adds about £840 to your yearly payroll burden.

Employee Expectations

While employer National Insurance Contributions increases are paid by employers, employees may still have questions, especially if their take-home pay looks different due to other payroll deductions, slower bonus or raise cycles. Make sure to commuNICsate clearly about what’s changing and why, to avoid confusion among the team. 

HR Budgeting and Forecasting Considerations

As a result of rising employer National Insurance Contributions, HR leaders must reassess impact in all areas of the workforce:

• Compensation strategy
• Headcount targets
• Talent mix (full-time vs. part-time contractor)
• Pay band structures

Some companies may also rethink staffing altogether. There’s also increased interest in flexible models, such as hiring contractors. This allows companies to maintain workforce capacity while reducing exposure to employer-based payroll obligations like NICs.

Multi-Country Employers

For companies hiring in multiple countries, NICs change in the UK require careful separation in global payroll systems. Even small misalignments in classification or thresholds can lead to overpayment or compliance risk.

Global Employers & EOR Impact

If you're hiring UK-based talent through an Employer of Record (EOR), your provider is responsible for executing compliant NICs payments. However, since you still carry the legal liability, it’s critical to ensure your provider is up to date.

Slasify’s EOR service handles UK tax registration, applies the correct NICs thresholds, and helps you claim Employment Allowance if eligible. This reduces risk, simplifies cross-border compliance, and ensures payroll accuracy for your teams.

4. Recommended Actions for Employers

To minimize risks and impact, we recommend that employers take the following actions:

1. Confirm Employment Allowance eligibility: Many firms that were previously disqualified can now benefit from the increase.
   
   
2. Review payroll software and NI calculators: Make sure the software & tools have the latest NICs thresholds and rates updated.
   
   
3. Consult with your payroll provider or EOR partner: Ask if their platforms and advisory teams are NICs-ready to provide support and guidance on current & any upcoming changes.
    
4. Review your 2026 payroll budgets: You must factor these elevated NICs baselines directly into your 2026 global hiring and compensation forecasts.
   
   
5. Adjust salary projections or HR budgets: You can take actions such as increasing pension contributions or equity to offset rising payroll taxes.
   
   
6. CommuNICate changes clearly to staff: Be sure to let your employees know of the changes made to their salary structure, so there’s no misunderstanding. 

Keeping your HR and payroll teams up to speed is especially important if your company operates in multiple countries. A common mistake companies make is intentionally misclassifying workers as contractors to avoid paying the mandatory employer contribution. Always ensure you understand the boundaries by reviewing our guide on Contract of Service vs Contract for Service to prevent severe HMRC penalties.
