The 2024 Autumn Budget introduced significant changes to employer National Insurance (NI) contributions, set to take effect in April 2025. With payroll costs rising for employers of all sizes, it’s vital for businesses to prepare for these sweeping changes now to mitigate their impact.

This article outlines the key changes, their implications, and additional considerations for employers.

What Are the Changes?

From April 2025, businesses will face three major changes to National Insurance:

  • Higher Employer NI Rate: The contribution rate will increase from 13.8% to 15%.
  • Lower Earnings Threshold: Employers will begin paying NI on employee earnings above £5,000, reduced from the current threshold of £9,100.
  • Removal of the £100,000 Eligibility Cap for Employment Allowance: Businesses with an employer NI liability exceeding £100,000 will now qualify for the Employment Allowance, enabling more employers to benefit from the increased allowance of £10,500.

These adjustments represent the largest shift in employer NI contributions in recent years, designed to generate £25 billion annually for public services.

How Will These Changes Affect Businesses?

The combined effect of the higher rate and lower threshold will significantly increase employer payroll expenses.

Additional Costs per Employee

  • Full-Time Minimum Wage Workers: An additional £770 annually per employee.
  • Median Salary Employees: An additional £900 annually per employee.

Impact on Small Businesses

The doubling of the Employment Allowance to £10,500 will provide relief to smaller employers. With the removal of the £100,000 cap, more businesses will now qualify for the allowance, helping to offset rising NI costs. However, businesses that do not qualify or have higher wage bills will still face significant increases.

Broader Economic Implications

The rise in employer NI contributions is part of a broader fiscal strategy aimed at bolstering public finances. Revenue from these changes will be directed toward public services, including the NHS and contributory benefits like the State Pension.

However, these measures come with potential economic challenges:

  • Business Confidence: Surveys show declining confidence among UK employers, with many citing increased tax burdens as a key concern.
  • Stagflation Risks: The combination of rising costs, slowing economic growth, and persistent inflation could lead to stagnation in the economy, as businesses delay investments or cut back on hiring.

These factors underline the importance of strategic planning for employers navigating this evolving economic landscape.

What Sectors Will Be Most Affected?

Certain industries are expected to feel the impact of these changes more acutely:

  • Retail and Hospitality: Sectors with high employee headcounts and lower average wages will see steep increases in payroll costs.
  • SMEs (Small and Medium-Sized Enterprises): Businesses with moderate payrolls may benefit from the Employment Allowance but still face challenges from higher wage bills.
  • Part-Time Workforce: The lower earnings threshold will disproportionately affect businesses employing part-time workers, increasing costs for roles previously below the NI threshold.

What Are Business Leaders Saying?

Several prominent business leaders have expressed concern about the pace and scale of these changes:

  • Currys CEO Alex Baldock described the changes as contributing to “depressed hiring” and noted the likelihood of increased automation and offshoring to manage rising costs.
  • Sainsbury’s CEO Simon Roberts highlighted that the changes would drive inflation, particularly in essential goods like fresh food, and urged the government to phase in the changes more gradually.

These comments reflect widespread apprehension about the changes’ impact on employment, investment, and pricing across multiple industries.

Recommendations for Employers

Given the complexity and financial impact of these changes, employers are encouraged to take proactive steps to prepare:

  1. Review Payroll Budgets: Assess the financial implications of the NI changes on your workforce and forecast future costs.
  2. Consult with Advisors: Work with financial advisors or tax professionals to understand the specific impact on your business and explore potential cost-saving strategies.
  3. Stay Informed: Monitor government updates and resources to ensure compliance with the new regulations.

By planning ahead, businesses can better navigate these challenges and minimise disruption.

Final Thoughts

While the 2025 National Insurance changes mark a significant shift for UK employers, proactive planning and informed decision-making can help businesses adapt successfully. By staying ahead of these changes, you can minimise disruption and position your company for resilience in a challenging economic landscape.
