National Insurance contributions for self-employed Running your own business means you handle almost everything yourself – including the National Insurance that builds your future State Pension rights. Many self-employed people and company directors leave gaps in their record without realising it, only to discover later that their pension is lower than expected.
In this article, we’re going to be taking a look at National Insurance contributions for self-employed workers in the UK, and how you can protect your qualifying years so you receive the full amount when the time comes. If you would like to find out more, feel free to read on.

What National Insurance the self-employed pay in 2026/27
As a sole trader or partner you pay two main types of National Insurance: Class 2 and Class 4. The rules changed a few years ago, so the system is simpler than it used to be.
If your annual profits are £7,105 or more (the Small Profits Threshold for 2026/27), Class 2 contributions are treated as paid automatically. You do not send any extra money for Class 2. This still counts as a qualifying year towards your State Pension.
If your profits are below £7,105 you can choose to pay voluntary Class 2 contributions. The rate for 2026/27 is £3.65 a week. Paying them keeps your National Insurance record intact and helps you build towards the full State Pension.
Class 4 is the main contribution for most self-employed people. You pay it on profits above £12,570:
- 6% on profits between £12,570 and £50,270
- 2% on profits above £50,270
These amounts are collected through Self Assessment along with your income tax.
You can confirm the latest figures on the official GOV.UK self-employed National Insurance rates page.
How these contributions link to how much is the state pension 2027
National Insurance contributions for self-employed Every qualifying year of National Insurance moves you closer to the full new State Pension. For the 2026/27 tax year the full rate is £241.30 a week (about £12,548 a year). You normally need 35 qualifying years to receive that amount.
If you have gaps – perhaps from low-profit years, time spent building the business, or periods of illness – your eventual weekly payment will be reduced. That is why understanding National Insurance contributions for self-employed people matters so much when you look at how much is the state pension 2027.
You can check your current forecast and any missing years free of charge on GOV.UK. The earlier you spot a gap, the cheaper and easier it is to fill.
Paying voluntary contributions to protect your record
If your profits sit under the Small Profits Threshold, voluntary Class 2 is usually the cheapest way to buy a qualifying year. Class 3 contributions (the general voluntary rate) cost far more – currently around £18–£19 a week – so Class 2 is the better option while you are still self-employed.
You can pay voluntary Class 2 through your Self Assessment return or by contacting HMRC directly. Keep records of any payments so you can prove the years later if needed.
Many business owners also use periods of higher profit to make sure they stay above the threshold and keep the automatic Class 2 credit.
Practical steps for business owners this year
National Insurance contributions for self-employed Review your National Insurance record at least once a year. Log into your personal tax account and download the statement. Mark any years that show as incomplete.
If you are close to State Pension age or already planning your exit from the business, calculate how many more qualifying years you still need. Paying a few voluntary Class 2 contributions now can make a noticeable difference to the weekly amount you eventually receive.
Company directors sometimes take a mix of salary and dividends. Only the salary portion attracts National Insurance, so check that your employment income is high enough to create a qualifying year if you want the State Pension credit.
Finally, treat National Insurance as part of your long-term business plan rather than just another tax. The contributions you make today directly affect how much is the state pension 2027 you will be able to claim.
We hope that you have found this article enlightening in some way and that the clear picture of National Insurance contributions for self-employed people helps you keep your State Pension record on track. Check your forecast, fill any gaps while the cost is still low, and build the rest of your retirement savings on top of a solid foundation.
