How Much National Insurance Do I Pay If I’m Self-Employed?


As a self-employed individual in the UK, managing your finances includes understanding and handling your tax and National Insurance responsibilities. This can seem like a maze at times, but don’t worry—we’re here to simplify things. Let’s look into what National Insurance contributions you need to make, why they matter, and how to go about it all.

What is National Insurance?

National Insurance is not merely an additional tax—it’s crucial for securing your entitlements under the UK’s social security system. The money you pay towards National Insurance goes into building your rights to the state pension and other benefits like maternity and job seekers’ allowance. Essentially, your National Insurance contributions ensure you are covered for future needs.

Types of National Insurance Contributions for Self-Employed People

As a self-employed individual, there are mainly two types of National Insurance you’ll deal with: Class 2 and Class 4. What you pay depends on your business profits, the income you have left after your expenses.

1. Class 2 National Insurance Contributions

Starting from April 2024, if your business profits are £6,725 or more annually, you must pay Class 2 contributions, which are set at £3.45 a week. These contributions are vital as they count towards your state pension and other entitlements.

If your earnings are below this threshold, you can pay voluntary Class 2 contributions. Opting for voluntary contributions is wise as they ensure your National Insurance record is maintained, which helps safeguard your entitlements to certain state benefits. 

2. Class 4 National Insurance Contributions

Once your profits exceed £11,909 for the tax year, you’ll need to pay Class 4 contributions. This is how it breaks down:

– You’ll pay 10.25% on any profit between £11,909 and £50,270.

– Profits above £50,270 are charged at a lower rate of 3.25%.

These contributions do not count towards your state pension but are required as part of your overall tax and National Insurance obligations.

Paying Your National Insurance

Self-employed individuals handle their National Insurance through Self Assessment. You must complete a self-assessment tax return each year, which captures your income and expenses. This return is used to calculate not only your income tax but also how much National Insurance you owe. If you’ve opted to make voluntary contributions, these are handled via your Self-assessment tax return.


It’s essential to get this right, as payments towards Class 2 and Class 4 contributions are treated as having been paid only once they are reported and calculated through this process.


Why Paying National Insurance is Crucial

While it might seem like an additional burden, paying into National Insurance secures your access to the state pension and other benefits, which can prove essential during different stages of life or in times of need, employed people have these contributions automatically deducted from their wages, but when you’re self-employed, it’s all on you to ensure these are paid correctly.

Helpful Tips for Managing Your Contributions

– Keep Detailed Records: This will simplify your Self Assessment tax return and ensure you’re paying the correct amounts.

– Budget for Contributions: Set aside money regularly to cover your tax and National Insurance. This avoids any surprises come the deadline.

– Seek Professional Advice: If you’re ever in doubt, consulting with a financial advisor or accountant can help clarify your obligations and ensure you’re taking advantage of any available benefits.

Staying Informed

Remember, rates and thresholds may change with each budget, so it’s essential to stay updated through official channels like the HM Revenue and Customs (HMRC) website.


Navigating tax and National Insurance when you’re self-employed can be tricky, but with the proper knowledge and preparation, you can handle it like a pro. By maintaining your National Insurance record and making the appropriate contributions, you’re investing in both your present and your future, ensuring you’re covered no matter what comes your way. Now, it’s time to get back to business, knowing your financial bases are covered!
