National Insurance (NI) needs to be paid by both employed and self-employed workers. Employers are obliged to pay National Insurance (NI) contribution on the salary as well as benefits given to the employees. Benefits that are liable to contributions may include provision of medical insurance and company cars. An employer is responsible for deducting income tax as well as NI contributions from the salary paid to employees. Apart from an employee’s own contributions, an employer pays their share of the NI contribution (this is an additional cost above the gross salary paid to the employee). In all, there are 6 classes of National Insurance contributions (NICs):

Class 1 – paid by employees through the employer as well as by the employers themselves

Class 2 – paid by self-employed individuals

Class 3 – voluntary contributions by individuals

Class 4 – paid by self-employed persons as a percentage of profit

The other two which apply to employers are Class 1A and Class 1B

How to calculate employers National Insurance for different class

Class 1: These payments are collected by employers and paid through the pay-as-you-earn (PAYE) system. An employer contribution is computed as a percentage of employee earnings over a certain amount and is applied to the benefits provided to an employee. There are a enormous number of Class 1 categories applying to employees in various circumstances. However, a special calculation applies to directors.

  • Class 1A payments are paid by employers and others on benefits provided to employees.
  • Class 1B contributions are paid by those employers who have settled on a PAYE Settlement Agreement with HM Revenue and Customs (HMRC). They are computed on the collective value of the items covered by the agreement and the tax payable by the employer under the agreement. These contributions are paid at the same rate as Class 1A but do not offer any benefit entitlement to individual employees.
  • Class 1A and Class 1B rates

    Employers pay Class 1A and 1B NI once a year on expenses and benefits they give to their employees. The rate for the tax year 2017-18 and 2018-19 is 13.8%

    Tax thresholds and rates

    Let’s understand this through an example. If an employee is in category A and earns £1,000 in a week, the computation for the year 2018-19 will be:

    • No amount payable for the initial £162
    • Between £162.01 and £892 @12% = [£730 * 12% =£87.6]
    • On the remaining earnings above £892 @2% = [£ 108 * 2% = £2.16]
      Hence, an employee’s National Insurance payment, for the week, will be £8.76

    Employers NIC calculation and filing

    Within each class there are many categories of contributions and the rates for each are published in an electronic table form by HMRC. An employer is responsible for allocating the correct table for each employee depending on a lot of criteria. The rate payable by employee and employer is determined by the suitable table. The major responsibility of an employer is to:

    • Deduct employee Class 1 contributions through the payroll
    • Pay employer Class 1A contributions following the end of the tax year on benefits provided to employees and
    • if a pay-as-you-earn settlement agreement has been signed, to pay employer Class 1B contributions after the end of the tax year

    Most filing with the HMRC can be done via the online PAYE system. In addition, all employers are required to file an employer annual return online. Online forms must be filed:

    • when an employee joins or leaves employment
    • when a new employee joins but does not have a P45 form from a previous employer
    • when the employer starts paying a new pension or annuity
