Employer's National Insurance is a crucial component of the UK's tax system and a significant cost for businesses. It is a contribution paid by employers for each of their employees, calculated on their earnings. These funds are vital for financing public services, including the NHS, state pensions, and various welfare benefits. For any business with staff, understanding and budgeting for these contributions is a fundamental part of financial management.
The calculation is based on an employee's gross pay. Contributions are only paid on earnings above the 'Secondary Threshold'. For the 2025/26 tax year, the rate is 15% on earnings above £5,000. This means if an employee earns less than the threshold, there is no employer NI to pay. This system ensures that the contribution scales with the employee's earnings. This Calculator Site tool helps you model these costs accurately.
Important: Employment Allowance Rules
The Employment Allowance can reduce your annual employer NICs bill by up to £10,500, but not all businesses are eligible. For instance, companies with only a single director earning above the Secondary Threshold, or those with an employer NICs liability of £100,000 or more in the previous tax year, cannot claim it. Always check official guidance to confirm your eligibility.
Employer NI is a business running cost and is a tax-deductible expense, meaning it can be deducted from profits before calculating your Corporation Tax. To understand the full impact on an employee's salary, use our Take-Home Pay Calculator.
