What are the different National Insurance contribution rates?

An employee’s Class 1 contributions are made up of two parts – those paid by the employee themselves (deducted from their wages and known as Employee’s National Insurance) and those paid by their employer (known as Employer’s National Insurance). How much is deducted depends on the category letter applied to the employee and how much of their earnings fall into each category.

The National Insurance rates for employees in tax year 2020/21 are currently set as:

Once a year, employers have to pay Class 1A and Class 1B National Insurance on any expenses or benefits that they give to their employees. The current rate for this (for tax year 2020/21) is 13.8%.

What are the different category letters and what do they mean?

Every employee is issued with a National Insurance category letter which tells their employer’s payroll how much National Insurance to deduct from their wages. You can find out your category letter by checking your payslip – it will be shown on there. Most employees have the category letter A.
