How much National Insurance do I pay?

This comprehensive guide looks at National Insurance for individuals and employees, the rates applicable and how much they should expect to pay.

How is National Insurance calculated? 

As a full or part-time employee, you will have a National Insurance category letter which employers use when submitting payslips and handling their payroll. This helps employers to calculate how much you both need to contribute. Most employees are in category A. However, there are additional categories that you could find yourself placed depending on your individual situation, including: 

In addition, there are different ‘classes’ of NICs that you must pay, depending on your income situation: 

What is the NI threshold? 

There is a National Insurance threshold for paying Class 1 National Insurance. In fact, there are six thresholds for paying Class 1 NICs. You must only pay NICs on earnings above the lower earnings limit. 

Class 1 NIC thresholds Monthly Weekly
Lower Earnings Limit £533 £123
Primary Threshold £1,048 £242
Secondary Threshold £758 £175
Upper Earnings Limit £4,189 £967
Upper Secondary Threshold £4,189 £967
Apprentice Upper Secondary Threshold £4,189 £967

 

National Insurance rates 

The rate of NIC you pay is a percentage of your overall weekly or monthly income. Your employer will deduct Class 1 NICs from your pay. 

The government announces the annual changes to National Insurance rates each year in the Budget. If you are wondering how much National Insurance Contributions for employees are in the current tax year, read on: 

From 6th April 2024 to 5th April 2025

Income (monthly) Class 1 NIC rate
£1,048 - £4,189 8%
Above £4,189 2%

 

How much NI does an employer pay? 

Employers’ National Insurance contributions are covered under ‘secondary’ Class 1 contributions. The ‘primary’ contributions being the employees’ National Insurance contributions. Both are collected by HMRC through the Pay As You Earn (PAYE) system. 

How much an employer pays in Class 1 NICs depends on their employees’ salary and their NI category letter: 

Income (monthly) Class 1 (secondary) NIC rate
Above £758 13.8%

Employers can use the employment allowance to lower their National Insurance payments by up to £5,000 per year. This reduction is available exclusively to small businesses with total NIC bills of less than £100,000. 

All employees under the age of 21 and apprentices under the age of 25 are exempt from employer Class 1 NICs, unless they earn £4,189.01 a month or higher.

How much National Insurance do I pay if I am self-employed? 

From April 2024, if your self-employed profits are £6,725 or more per annum, you will be treated as having paid Class 2 NICs to protect your National Insurance record. You do not have to make any Class 2 NIC payments. If your profits are less than £6,725 per annum, you can choose to make voluntary Class 2 NIC payments.

Those with self-employed profits above £12,570 in the 2024/25 tax year will also incur Class 4 NICs, paid at 6% on profits above this threshold. NICs are payable at a rate of 2% on profits above £50,270 in 2024/25. 

There are some who may opt to make voluntary contributions instead. Religious ministers, exam invigilators, investors and property business owners are exempt from Class 2 NICs, but these individuals may not qualify for certain state benefits like a state pension if they do not make sufficient contributions. That’s where voluntary NICs come in to play – allowing exempt individuals to make up any missing years if necessary. 

If you are both employed and self-employed 

If you are employed and self-employed, you will pay: 

Every year, you must send a self-assessment tax return to declare your earnings from self-employment and employment.
