Understanding Class 4 National Insurance Contributions for Self-Employed Professionals



Navigating the landscape of Class 4 National Insurance contributions can be challenging for self-employed professionals. Ensuring compliance and understanding your obligations regarding these contributions is essential. This guide will walk you through the intricacies of Class 4 National Insurance, helping you better manage your finances and obligations to HMRC.


Class 4 National Insurance is typically payable by self-employed individuals who earn profits above a certain threshold. These contributions fund state benefits, including the state pension, maternity allowance, and bereavement benefits. Understanding Class 4 National Insurance will help you stay compliant and make informed financial decisions, ensuring that you only pay what you owe without any overcharges.


Class 4 National Insurance is calculated based on your annual profits. It is essential to keep accurate records and calculate your contributions correctly. Below, we break down the contribution rates, thresholds, and calculation methods to provide a comprehensive guide tailored to your needs.

Contribution Rates Explained

Class 4 National Insurance contributions (NICs) are calculated based on your annual profits. For the 2023-24 tax year, you’ll pay 9% on profits between £11,910 and £50,270. Once your profits exceed £50,270, the rate drops to 2% on any additional earnings.


These contributions apply to self-employed individuals and are in addition to Class 2 NICs. It's important to factor these into your tax planning to avoid any surprises when calculating your total tax liability for the year.

Annual Thresholds

Class 4 National Insurance contributions only apply if your profits exceed the Lower Profits Limit. For the 2023-24 tax year, this threshold is set at £12,570. If your annual profits fall below this amount, you won’t need to make any Class 4 contributions.


However, if your profits surpass this limit, you will need to contribute a percentage based on the established rates for that year. This ensures that lower-earning self-employed individuals are not subject to additional NICs.

How to Calculate Contributions

Calculating Class 4 National Insurance accurately is vital to avoid any surprises when it's time to file your Self-Assessment tax return. The calculations are straightforward and based on your annual profits, but they must fit within the defined thresholds.


The main rate for Class 4 National Insurance applies to profits ranging from the Lower Profits Limit up to the Upper Profits Limit. For the tax year 2023-24, the lower limit is set at £12,570, while the upper limit is £50,270. Profits between these two thresholds are subject to a 9% contribution rate. Profits exceeding the upper limit attract an additional 2%.


Accurate record-keeping is crucial for calculating your contributions precisely. The Pie Tax App and the expert tax assistants available on the Pie app can simplify this process, ensuring you remain compliant and avoid overpaying your contributions.

How to Pay Your Contributions

Paying your Class 4 National Insurance contributions is an integral part of your annual Self-Assessment tax return. Self-employed individuals must complete a Self-Assessment tax return each year, detailing their income and expenses, including their National Insurance contributions.


You can file your Self-Assessment online through the HMRC portal. When filing your return, ensure all your income and expenses are accurately reported to calculate the correct amount of Class 4 National Insurance contributions you owe. The Pie Tax App simplifies this process by guiding you through each step, ensuring accuracy and compliance.


Once your Self-Assessment is complete, HMRC will inform you of the tax and National Insurance contributions due. Make sure you adhere to the deadlines to avoid any penalties. If required, the Pie Tax App can send reminders to ensure you meet all your payment obligations on time.
