Employer NI calculations and legislation is fairly straightforward but there are a number of elements therein which change periodically and affect the overall employer NI calculation and costs. Let's look at the FAQ we receive in regard to employer NI, we have listed the questions in an order which we hope helps to build/consolidate your knowledge of National Insurance from an employer's perspective.

What are employers National Insurance Contributions?

Employer National Insurance Contributions (also referred to as Employer NI, ENIC's, Employer NIC's) are the portion of national insurance contributions which are paid by the employer. The combined national insurance payment consists of employee contributions and employer contributions. The contributions go towards social security costs which include paying for the NHS, Pensions, Benefits and Social Care. National insurance contributions are ring-fenced which means they cannot be used for any other government funded initiatives, they must be used for social security funding only.

How do Employer NI Contributions affect the cost of employment?

Employers NI contributions have quite an impact on the cost of employments as the NI contributions are paid as a percentage of an employees pay. Let's look at a simple example which excludes the employers NI allowance for simplicity. For every £10 that an employer pays an employee, the employer must pay an additional £ 1.38 to HMRC for employer NI contributions. If we consider that against the current minimum wage which is currently £ 8.91 (for the those who are 25 years of age and older), the real cost of that minimum wage when factoring in employers NI is £ 10.14 .

This additional cost that employers pay is often overlooked by the employee as the contributions occurs outside of their influence. The money being paid to HMRC directly by the employer.

To complete the employer cost of employment point, employers are now required to offer a company pension scheme and contribute towards the employees' pension. The U.K. Government defines minimum contributions to company pensions, currently (2024 Tax Year) this is 3 %. Let's use the same example for the company pension cost as we did in our Employer NI example. For every £10 that an employer pays an employee, the employer must pay an additional £ 0.30 into a company pension scheme for employer pension contributions. If we consider that against the current minimum wage which is currently £ 8.91 (for the those who are 25 years of age and older), the real cost of that minimum wage when factoring in employer pension contributions is £ 9.18.

If we combine these two elements our cost of employment for every £10 paid is £ 10.41. The employee on the other hand when considering NICs, PAYE and company pension contributions will see around £ 7.31. (based on a 36-hour working week at £10 per hour with 5% pension contribution). This is of course a simplified overview, but it is important as an employer to understand two key point here:

  1. Employer NI increases your employment costs beyond the basic salary (as do company pension contributions). It is important to factor in those costs when completing financial reviews and salary cost analysis and/or forecasting.
  2. What you pay your employees is not what they have to spend. In our simple example, our employee on a £10 an hour rate cost £11.68 but they received £8.20 in hand. That is approximately 70% take home based on that actual cost of employment. This percentage decreases the more the employee is paid as income tax rates increases as the salary transition through the income tax thresholds.
