Class 1 National Insurance

Class 1 National Insurance is deducted at source from salaried income.

There are two types of Class 1 National Insurance, Employees Class 1 National Insurance and Employers Class 1 National Insurance. Employees National Insurance is paid by the employee on salaried/bonus income received. Employers National Insurance is paid by the employer on salaried/bonus income paid to the employee.

As a contractor it is possible to reduce the level of Class 1 National Insurance paid by claiming legitimate business expenses incurred in the course of a temporary site based contract. The value of such expenses reduces the gross level of salary and consequently reduces the amount of Class 1 National Insurance payable.

What is Class 1 Employees National Insurance?

Class 1 Employees National Insurance is payable by an employee on salaried income. It is levied at a rate of 11% between the primary threshold and the upper earnings limit. Any Income above the upper earnings limit is taxed at a rate of 1%. Therefore a ‘cap’ is in place to reduce the level of national insurance paid by high earners.

Employees Class 1 National Insurance is applied as detailed below:
  1. 0% below the Primary threshold of £110 per week
  2. 11% between the Primary threshold (£110 pw) and the Upper Earnings Limit (£844 pw)
  3. 1% on earnings above the Upper Earnings Limit of £844 per week

What is Class 1 Employers National Insurance?

Employers National Insurance is payable by the employer on an employees salary and benefits. Employers National Insurance is levied at a flat rate of 12.8% above the secondary threshold; there is no upper limit or ‘capping’.

Employer Class 1 National Insurance is applied as detailed below:
  1. 0% below the Secondary threshold of £110
  2. 12.8% above the Secondary threshold of £110

Why do Contractors pay Employers National Insurance?

An Umbrella Company provides a ready made structure to deal with contract income. Invoices are raised, expenses are processed, and net payments are made etc all in return for a certain margin of gross billings. The margin an Umbrella Company receives either includes or excludes Employers National Insurance. Do not be fooled by Umbrella Companies who offer a low margin but exclude Employers National Insurance from it, you still have to pay Employers NI. See ‘Umbrella Companies and Employers NI’ for further details.
