# National Insurance Rates and Categories

What are National Insurance Contribution rates and category letters? Employee earnings and a National Insurance category letter determine the amounts deducted and the rates you must pay.

NI CONTRIBUTION RATES: Find out what National Insurance rates and category letters mean for your situation.

This guide explains how Class 1 National Insurance contribution rates work for the current tax year 2021 to 2022.

All Class 1 National Insurance rates for employees are made up using two separate contributions:

1. An amount deducted from employee pay (called employee NI).

2. An amount paid by an employee's employer (called employer NI).

The table shows the employee National Insurance category letter flowchart. This is useful for employers to use when they run off the payroll. It can also help employers and employees work out how much they both need to contribute.

## Self-employed National Insurance Rates and Exemption

As a rule, National Insurance contributions for those who are self-employed are:

• Class 2: Self employed with profits £6,515 or more a year.
• Class 4: Self employed with profits £9,569 or more a year.

Note: You can work out your annual profits by deducting your total expenditure from your self-employed income.

### How Much is Class 2 National Insurance?

• Class 2 Rate for tax year 2021 to 2022: £3.05 a week.
• Class 4 Rate for tax year 2021 to 2022: 9% on profits between £6,515 and £50,270 (2% on profits over £50,270).

There are times when you do not need to pay NICs or cannot qualify for NI credits. But, you can choose to pay voluntary National Insurance contributions. You would be topping up any gaps that exist in your NI record.

Paying voluntary National Insurance counts towards many state benefits and towards the UK State Pension.

Employees usually pay Class 3 contributions whereas those who are self-employed or living abroad may choose to pay voluntary contributions instead.
