Running a business means keeping a close eye on costs, and one expense that can quickly add up is employer National Insurance. Since employers pay Class 1 National Insurance contributions on employee earnings above certain thresholds, the total bill can become significant as a team grows.
The good news is that there are legitimate ways to reduce employer National Insurance costs. Some involve taking advantage of government incentives, while others require careful workforce planning. Understanding the available options can help improve profitability without compromising the quality of your workforce.
What Is Employer Class 1 National Insurance?
Employer Class 1 National Insurance, often referred to as secondary National Insurance contributions, is paid by employers on employee earnings above the relevant threshold.
For many businesses, this represents a substantial payroll expense. While it is a necessary cost of employing staff, there are several reliefs and exemptions available that can reduce the amount payable.
Understanding these reliefs is the first step towards lowering payroll costs and improving cash flow.
Claim the Employment Allowance
One of the most effective ways to reduce employer National Insurance is by claiming the Employment Allowance.
Eligible employers can reduce their annual employer National Insurance bill by up to £10,500. This relief is particularly valuable for small and medium-sized businesses looking to control employment costs.
The allowance is not applied automatically. Employers must actively claim it through their payroll software.
However, there are restrictions. Companies where the only employee earning above the secondary threshold is also a director generally cannot claim the allowance.
For owner-managed businesses, it may be worth reviewing employment arrangements to determine whether eligibility exists. In some cases, employing another qualifying worker may open access to the allowance.
Can Hiring More Part-Time Workers Reduce National Insurance?
The answer is yes, in certain situations.
Employer National Insurance is calculated separately for each employee. This means every employee benefits from their own earnings threshold before contributions become payable.
As a result, two part-time employees may generate a lower National Insurance bill than one full-time employee earning the same combined amount.
Example of the Saving
Suppose one employee earns £4,000 per month.
The employer pays National Insurance on earnings above the monthly secondary threshold.
If the same payroll cost is split between two employees earning £2,000 each per month, both employees benefit separately from the threshold.
The result is a lower overall National Insurance liability and an annual saving for the employer.
Of course, staffing decisions should always be based on operational needs first, with tax efficiency viewed as a secondary benefit.
Employ Workers Under the Age of 21
Businesses employing workers under 21 can benefit from a higher secondary threshold.
For the 2026/27 tax year, employer National Insurance is not generally payable until earnings exceed £50,270 per year.
This can produce substantial savings when compared with employing someone over the age threshold.
For businesses in retail, hospitality and service sectors where younger workers often form part of the workforce, this relief can significantly reduce payroll costs.
Take On Apprentices
Apprentices can create value for both employers and employees.
From a business perspective, apprentices help develop future talent while potentially reducing payroll taxes.
Where an apprentice is under 25 and meets the statutory definition required by National Insurance legislation, employers can benefit from the apprentice upper secondary threshold.
As with younger workers, this higher threshold means reduced employer National Insurance contributions.
In addition to the tax advantages, apprenticeships can help address skills shortages and improve long-term workforce development.
Employ Armed Forces Veterans
Another often overlooked relief applies to armed forces veterans.
Employers hiring veterans in the first twelve months after they leave military service can benefit from a higher National Insurance secondary threshold.
The measure supports veteran employment while helping businesses reduce payroll costs.
For employers facing recruitment challenges, this can represent both a commercial and social benefit.
Consider Freeports and Investment Zones
Businesses located in designated Freeports and Investment Zones may benefit from additional incentives.
One of these incentives is a higher employer National Insurance threshold for eligible new employees working within Special Tax Sites.
For qualifying businesses, this can lead to meaningful savings during the employee’s first years of employment.
While relocation should never be based solely on National Insurance savings, businesses planning expansion may wish to include these incentives when evaluating potential locations.
Don’t Forget the Corporation Tax Benefit
Although employer National Insurance is a cost, it is also a deductible business expense.
This means that employer contributions reduce taxable profits when calculating Corporation Tax or business profits for tax purposes.
While this does not eliminate the National Insurance bill, it does soften the overall financial impact.
Key Takeaways
Reducing employer National Insurance is not about avoiding obligations. It is about ensuring you claim every relief and incentive available.
The Employment Allowance remains one of the most valuable opportunities for eligible businesses. Beyond that, workforce planning, apprenticeships, younger employees, veterans and location-based incentives can all contribute to lower payroll costs.
Used together, these measures can improve cash flow, strengthen profitability and free up resources for future growth.
Conclusion
Employer National Insurance is a significant business expense, but it should not be viewed as an unavoidable burden that cannot be managed. By understanding the available allowances, exemptions and workforce incentives, businesses can legally reduce costs while continuing to invest in their people.
