National Insurance for Self-Employed Delivery Drivers: Class 2 & Class 4 Explained (2025/26)
National Insurance for Self-Employed Delivery Drivers: What You Actually Owe
National Insurance is one of the most misunderstood taxes for UK gig workers. Unlike Income Tax, which most people have heard of, National Insurance contributions (NICs) catch many delivery drivers off guard — often resulting in unexpected bills or, worse, gaps in their State Pension record.
If you're self-employed as an Uber Eats, Deliveroo, or Amazon Flex driver, you may owe two types of National Insurance: Class 2 and Class 4. This guide explains both, shows you exactly how much you'll pay, and reveals how they affect your future pension.
What Is National Insurance and Why Does It Matter?
National Insurance is a tax on earnings that funds:
- The State Pension (you need 35 qualifying years for the full amount)
- Maternity Allowance
- Bereavement Support Payment
- The NHS (partially)
If you don't pay enough NI, you could miss out on qualifying years for your State Pension — which is currently worth up to £221.20 per week (2025/26). That's over £11,500 a year in retirement.
The Two Classes of NI for Self-Employed Workers
Employed workers pay Class 1 NI (deducted by their employer). Self-employed workers pay different classes:
| Class | Who Pays | Rate (2025/26) | Threshold |
|---|---|---|---|
| Class 2 | Self-employed with profits above Small Profits Threshold | £3.45 per week | Profits above £6,725/year |
| Class 4 | Self-employed with profits above Lower Profits Limit | 6% on £12,570–£50,270; 2% above £50,270 | Profits above £12,570/year |
Class 2 National Insurance: The Pension Builder
Class 2 NI is a flat-rate contribution that costs £3.45 per week (£179.40 per year). You pay it if your self-employed profits exceed £6,725.
Why it matters: Class 2 is what builds your State Pension entitlement. Each year you pay Class 2 counts as a "qualifying year." You need 10 years minimum to get any State Pension, and 35 years for the full amount.
What If Your Profits Are Below £6,725?
You won't be required to pay Class 2, but you can choose to pay voluntarily. At just £179.40 per year, it's one of the cheapest ways to build pension entitlement. Consider this carefully if you're just starting out or working part-time.
If you also have a PAYE job where you already pay Class 1 NI, you may already be building qualifying years through your employment. Check your NI record at gov.uk/check-national-insurance-record.
Class 4 National Insurance: The Profits Tax
Class 4 is the bigger one. It's calculated as a percentage of your annual profits:
- 6% on profits between £12,570 and £50,270
- 2% on profits above £50,270
Unlike Class 2, Class 4 doesn't count towards your pension — it's purely a tax on profits.
Worked Example: Delivery Driver Earning £18,000
| Calculation | Amount |
|---|---|
| Gross gig income | £18,000 |
| Allowable expenses (mileage: 12,000 miles) | -£5,900 |
| Net profit | £12,100 |
| Class 2 NI (£12,100 > £6,725) | £179.40 |
| Class 4 NI (£12,100 is below £12,570) | £0 |
| Total NI | £179.40 |
Worked Example: Higher-Earning Driver (£30,000 Profit)
| Calculation | Amount |
|---|---|
| Net profit | £30,000 |
| Class 2 NI (annual) | £179.40 |
| Class 4 NI: 6% on (£30,000 – £12,570) = £17,430 | £1,045.80 |
| Total NI | £1,225.20 |

How NI Works If You're Employed AND Self-Employed
Many gig workers also have a regular PAYE job. In this case:
- Your employer deducts Class 1 NI from your salary
- You pay Class 2 and Class 4 NI on your self-employed profits via Self Assessment
- There's an annual maximum for NI — if you earn a lot from both sources, HMRC may refund overpaid NI
The good news: your Class 1 contributions from employment already count towards your State Pension. So the Class 2 contributions from self-employment provide additional cover but won't give you "double" pension.
When and How to Pay NI
Both Class 2 and Class 4 are calculated and paid through your Self Assessment tax return. You don't need to make separate payments — they're included in your January 31st tax bill.
If HMRC asks for Payments on Account, your NI will be estimated and included in those advance payments too.
Common Mistakes to Avoid
- Ignoring NI in your tax budget: Many drivers calculate Income Tax but forget NI. Class 4 at 6% adds up quickly on higher profits.
- Assuming PAYE covers everything: Your employer's NI deductions don't cover your self-employed profits — you'll owe additional NI via Self Assessment.
- Not paying voluntary Class 2: If your profits are low, you might miss building pension years. The cost is small for significant long-term benefit.
- Overpaying when employed too: If you pay Class 1 and Class 4 on combined high earnings, check whether you've exceeded the annual maximum.
Frequently Asked Questions
Do I have to pay National Insurance if I only earn £5,000 from gig work?
If your profit (income minus expenses) is below £6,725, you don't have to pay Class 2. Below £12,570, you don't pay Class 4. But you should consider voluntary Class 2 to protect your pension.
Is Class 4 NI the same as Income Tax?
No. They are separate taxes calculated on the same profit figure. You pay Income Tax AND Class 4 NI — they're not alternatives.
Can I reduce my NI bill by claiming more expenses?
Yes. NI is calculated on your net profit, so legitimate expenses reduce both your Income Tax and your NI bill. Try our Deliveroo calculator to see how expenses affect your total tax.
Will I get a State Pension if I only do gig work?
Yes, provided you pay Class 2 NI (or voluntary Class 2 if below the threshold) for enough qualifying years. You need at least 10 years for any pension and 35 years for the full amount.
What happens if I don't pay National Insurance?
HMRC will charge interest and potentially penalties on unpaid NI. More importantly, you'll develop gaps in your pension record that could cost you thousands in retirement.
Conclusion
National Insurance might feel like an afterthought compared to Income Tax, but it's equally important — both for your legal obligations and your future pension. The key takeaways: Class 2 builds your pension (and it's cheap), Class 4 is calculated on profits above £12,570, and both are paid through Self Assessment.
