National Insurance for sole traders: the complete guide
Whatever industry you’re in, keeping on top of personal finances is vital for any sole trader. A vital element to this is monitoring what national insurance contributions you have to make.
National Insurance is a vital framework that underpins your contributions towards social security, healthcare, and state benefits. As a sole trader, you’ll normally need to pay Class 2 and Class 4 contributions, although there are some instances where you may be exempt.
Whether you're just starting your solo venture or seeking clarity on your obligations, this comprehensive guide will illuminate the importance of National Insurance and how it safeguards your business. Let's dive in.
What are the National Insurance Contributions (NICs) for self-employed people?
As a self-employed individual, you will be liable to pay National Insurance Contributions (NICs) between the ages of 16 and the state retirement age. Your state pension age can be determined using the calculator on GOV.UK.
Currently, self-employed individuals earning sufficient profits are required to pay two different classes of NICs: Class 2 and Class 4. The table below provides a summary of these classes. However, if you are a married woman or widow eligible for reduced rate contributions, Class 2 NIC is not mandatory for you. Additional special rules apply to share fishermen, volunteer development workers, examiners, and exam markers, which can be found on GOV.UK. Stay informed and fulfil your NIC obligations for a secure financial future.
Here is a summary of the NICs rates for the 2024/25 and 2025/26 tax years:
Class 2 NIC requirements
Self-employed profits PA | Class 2 NIC requirements | Notes |
£6,725 or below | Not required. Can choose to make a voluntary contribution. 2024/25 - £3.45 per week 2025/26 - £3.50 per week | Can choose to make a voluntary contribution in order to protect certain entitlements |
Between £6,725 and £12,570 | No payment required, treated as if paid | If above Small Profits Threshold - Class 2 NIC treated as if paid |
More than £12,570 | No payment required, treated as if paid | Class 2 NIC treated as if paid |
Class 4 NIC requirements
Self-employed profits PA | Class 2 NIC requirements | Notes |
£12,570 or below | Not required | No Class 4 NICs due, below the Lower Profits Limit |
Between £12,570 and £50,270 | 6% of profits | 6% charged on profits between the Lower Profits Limit (above) and the Upper Profits Limit (below) |
More than £50,570 | 2% of profits | 2% charged on profits above the Upper Profits Limit |
What are Class 2 National Insurance Contributions?
Class 2 National Insurance Contributions play a significant role in the financial obligations of self-employed individuals. Once you embark on your self-employment journey, you become liable to pay Class 2 NICs.
In most cases, individuals pay both Class 2 and Class 4 NICs, along with income tax through Self Assessment payments in January.
Class 2 NICs are payable as the following weekly flat rates:
2024/25 tax year - £3.45
2025/26 tax year - £3.50
From 2022/23, Class 2 NICs are not payable on profit above the NI Small Profits Threshold but below the personal allowance. If your profits are between £6,725 and £12,570 a year, there is no obligation to pay Class 2 NICs, as they are treated as already being paid. However, individuals earning less profit than the threshold can choose to make voluntary Class 2 NI contributions (£3.45 for 2024/25 and £3.50 per week for 2025/26).
This option is available through the Self Assessment tax return. Making voluntary payments can have its benefits, especially if you intend to claim Maternity Allowance before the usual Self Assessment payment date for the tax year.

Stay informed and up-to-date with your National Insurance obligations as a self-employed individual. By understanding the intricacies of Class 2 NICs and how they relate to your business profits, you can manage your finances effectively and ensure compliance with HMRC regulations.
What are Class 4 National Insurance Contributions?
Class 4 National Insurance Contributions are directly linked to taxable profits. For the tax years 2024/25 and 2025/26, you’ll need to pay Class 4 NICs if your self-employed profits exceed the Lower Profits Limit of £12,570 a year. Here are the thresholds:
Profits between £12,570 and £50,270 - 6%
Profits over £50,270 - 2%
If you earn more than £50,270 (the Upper Profits Limit), only profits above this threshold will be charged at the 2% rate. For example, if your self-employed business earned £84,440 in profit, the first £50,270 would be subject to the 6% rate, with the remaining £34,170 being subject to the 2% rate.
Your rate will be calculated by HMRC when you complete the Self Assessment tax return. Your statement will include a calculation for NICs defined by your profit.
For Class 4 NICs, you’ll usually pay the amount due to HMRC every six months as part of your payment on account (31st July each year) and/or your final Self Assessment payment (31st January each year). The payment on account is usually an estimate.
Class 4 NICs are typically paid alongside income tax, with two payment deadlines falling on 31st January and 31st July each tax year. This synchronised payment approach streamlines the contribution process, making it more manageable for self-employed individuals.
Staying informed about Class 4 NICs is paramount, as it ensures accurate and timely contributions to HMRC. Properly managing your tax obligations guarantees a smoother financial journey and compliance with tax regulations.
How do you register for Class 2 and Class 4 NICs?
When becoming self-employed, registering with HMRC covers both income tax and National Insurance contributions (NICs). To initiate the registration process, visit our guide on registering as a sole trader with HMRC.
Remember, failure to register your self-employment with HMRC may lead to rejected Class 2 NIC payments or inaccurately recorded contributions. It's crucial to follow HMRC's specific registration process for the self-employed, even if you already submit Self Assessment tax returns for other purposes.
Ensure you adhere to the proper procedures to avoid any discrepancies and ensure your contributions are appropriately accounted for.
How do you pay National Insurance Contributions?
Class 2 and Class 4 National Insurance Contributions (NICs) are conveniently calculated and paid alongside income tax liabilities, utilising the Self Assessment system.
For those who make payments on account, Class 4 NICs are included in the instalment calculations. Otherwise, Class 4 NICs are due on 31 January after the tax year concludes. Class 2 NICs, regardless of payment on account, are due on the same date.
When Class 2 NICs are essential for certain benefits, like Maternity Allowance, it's advisable to pay them before the Self Assessment deadline. This ensures timely entitlement to those benefits.
Alternatively, you have the option to make regular NIC payments throughout the tax year instead of a lump sum. By understanding the payment process and your entitlements, you can effectively manage your NIC obligations and secure any necessary benefits. Stay informed and plan accordingly to meet your financial responsibilities.
What are the exemptions to paying National Insurance Contributions?
Exemptions to paying National Insurance Contributions (NICs) apply from the 2022/23 tax year onwards for both Class 2 and Class 4 NICs. If your self-employed profits for the 2023/24 tax year fall below £6,725 (Small Profits Threshold), you are exempt from paying Class 2 NICs. Additionally, if your profits are less than £12,570 (Lower Profits Limit), you are exempt from both Class 2 and Class 4 NICs.
These exemptions ensure that individuals with lower profits or earnings below the specified thresholds are not obligated to make National Insurance Contributions, providing financial relief in certain circumstances.

Do you need to pay NICs if you are employed as well as self-employed?
In most cases, individuals who are both employed and self-employed are required to pay National Insurance Contributions (NICs). However, there is an exception: if you already pay the maximum amount of annual NICs through Class 1 and Class 2 contributions, you might not be obligated to pay the full amount of Class 4 NICs. In such situations, a 2% Class 4 NIC rate will apply only to profits exceeding £12,570 (for 2024/25 and 2025/26).
Your Class 4 NIC liability will be automatically calculated if you file your tax return online or submit your paper tax return by the due date (usually 31st October following the tax year end) as part of the Self Assessment process. Ensuring compliance with the Self Assessment process helps you accurately determine your NIC obligations and fulfill your financial responsibilities.
Who is eligible for Reduced Rate Contributions?
To determine if you qualify for the reduced rate, you can inquire using form CF9 (for married women) or form CF9A (for widows). These forms also allow individuals to renounce their right to pay reduced rate contributions if applicable.
