Class 2 National Insurance in 2026: What Changed

Class 2 National Insurance is no longer a tax most sole traders pay. Since 6 April 2024, self-employed people with profits at or above the small profits threshold (£7,105 for 2026/27) are treated as having paid it, so they get State Pension credit for free, while those below the threshold can choose to pay voluntary Class 2 at £3.65 a week. From 6 April 2026, a further change removed voluntary Class 2 for most people living or working abroad.

If you are self-employed in the UK, the practical question is no longer "how much Class 2 do I owe?" but "should I pay voluntarily, and does anything need to change on my tax return?" This guide explains the current rules, the April 2026 change for people abroad, who should pay, a worked example, and how Class 2 fits with Class 4. It is general information, not tax or financial advice; for your situation, check your National Insurance record on GOV.UK or speak to an accountant.

What is Class 2 National Insurance?

National Insurance contributions build entitlement to the State Pension and some contributory benefits. Self-employed people historically paid two classes:

• Class 2: a flat weekly amount, giving entitlement to the State Pension, Maternity Allowance, bereavement support and contribution-based Employment and Support Allowance.
• Class 4: a percentage of profits above a threshold, which raises revenue but does not itself add to your record. Our guide to Class 4 National Insurance covers the 2026/27 rates of 6% and 2%.

Class 2 was compulsory for anyone with profits above the small profits threshold until the end of the 2023/24 tax year. From 2024/25, the government abolished the obligation to pay, while keeping the benefit of a qualifying year.

Class 2 rates and thresholds for 2026/27

Item	2026/27 figure
Voluntary Class 2 weekly rate	£3.65 a week
Full year of voluntary Class 2 (52 weeks)	£189.80
Small profits threshold	£7,105 a year
Class 4 lower profits limit	£12,570
Class 4 rate between £12,570 and £50,270	6%
Class 4 rate above £50,270	2%

Figures are from GOV.UK's page on self-employed National Insurance rates.

What changed: compulsory to voluntary

The effect of the 2024 change depends on your profits:

Annual profits (2026/27)	Class 2 position	Class 4 position	Qualifying year?
Below £7,105	Nothing to pay; can pay voluntarily at £3.65 a week	None	Only if you pay voluntarily or get credits/employment elsewhere
£7,105 to £12,570	Treated as paid, free	None	Yes
Above £12,570	Treated as paid, free	6% / 2% on profits above £12,570	Yes

For sole traders between £7,105 and £12,570, this was a pure saving: they used to pay Class 2 and now pay nothing while still building their record.

The April 2026 change for people abroad

Until April 2026, many people who had lived or worked in the UK could pay voluntary Class 2 for years spent abroad, at the same low weekly rate, to build their State Pension. From 6 April 2026, the government removed access to voluntary Class 2 for periods abroad, for employees and most self-employed people, according to the GOV.UK policy paper. Key points:

• Exceptions remain for people treated as gainfully self-employed in the UK under a relevant social security agreement, and for volunteer development workers.
• People abroad who want to fill gaps generally pay Class 3 instead. New Class 3 applications for periods abroad must show at least 10 continuous years of UK residence or at least 10 qualifying years on their record.
• The government states Class 3 costs £767 a year more than voluntary Class 2 at 2026/27 rates, which works out at about £956.80 a year.
• Existing voluntary Class 2 payers abroad can apply for Class 3 without meeting the 10-year test if they apply before 6 April 2027. Contributions for years before 2026/27 are not affected.

If you are a UK freelancer planning to move abroad and keep billing UK clients, consider the National Insurance side before you go, as well as income tax residence.

Should you pay voluntary Class 2? Step by step

1. Check your National Insurance record on GOV.UK to see which years are qualifying and whether any are incomplete.
2. Check your State Pension forecast. You generally need 35 qualifying years for the full new State Pension and at least 10 for any.
3. Look at the year in question. Did you have employment earnings above the lower earnings limit, or credits (for example for Child Benefit for a child under 12, or caring)? If so, the year may already count.
4. Confirm your profits were below £7,105. Above that, Class 2 is treated as paid automatically.
5. If the year would not count otherwise, voluntary Class 2 at £189.80 is usually one of the best-value ways to add a year of State Pension.
6. Choose to pay on your Self Assessment return, and the amount is added to your bill due 31 January.

Voluntary Class 2 can also matter for Maternity Allowance. Self-employed people who want to maximise it can pay Class 2 for at least 13 of the 26 weeks they were self-employed in the relevant test period.

Worked example: three sole traders in 2026/27

These figures are illustrative.

	Aisha (illustrator, part year)	Ben (tutor)	Chloe (web developer)
Invoiced sales	£8,400	£15,800	£62,000
Allowable expenses	£2,100	£2,600	£7,000
Profit	£6,300	£13,200	£55,000
Class 2	£0 due; may pay £189.80 voluntarily	Treated as paid	Treated as paid
Class 4	£0	6% x £630 = £37.80	6% x £37,700 + 2% x £4,730 = £2,356.60
Qualifying year?	Only if she pays voluntary Class 2 (no other earnings)	Yes	Yes

Aisha has no job and no credits, so she ticks the voluntary Class 2 option on her return: £189.80 for a qualifying year. Ben and Chloe do nothing about Class 2, because their profits are above the threshold and the qualifying year is credited automatically. Note how much depends on the profit figure: if Aisha's allowable expenses were overstated, she might wrongly fall below the threshold, so accurate invoices and expense records matter. Our guide to allowable expenses for the self-employed shows what counts.

Common mistakes

• Paying voluntary Class 2 when not needed, because the year already counts through employment or credits.
• Assuming you can still pay Class 2 from abroad after April 2026.
• Using the trading allowance without realising that with no reported profit, you may not have a qualifying year; see our guide to the £1,000 trading allowance.
• Forgetting to register for Self Assessment. You still need to register as self-employed to report profits and pay Class 4; see how to register as self-employed.
• Missing the 31 January deadline, covered in our Self Assessment deadlines guide.

What if you have gaps from earlier years?

You can usually pay voluntary contributions to fill gaps in your record for the past six tax years. For years when you were self-employed in the UK with low profits, voluntary Class 2 at that year's rate is normally the cheapest option. For years when you were not self-employed, Class 3 is the usual route. Before paying anything:

• Check that the year is genuinely incomplete and not already covered by credits.
• Check your State Pension forecast to see whether the extra year actually increases your pension. If you will reach 35 qualifying years anyway, an extra year may add nothing.
• Get the payment reference from HMRC for the specific year, so the money is allocated correctly.

The figures can be striking. One year of voluntary Class 2 at 2026/27 rates costs £189.80, while a qualifying year typically adds around 1/35th of the full new State Pension each year for life. That is why HMRC's April 2026 change for people abroad was significant for expats. If HMRC's records or your forecast look wrong, raise it with HMRC before paying, because a missing credit or unrecorded employment year is cheaper to fix than to buy.

Class 2 for freelancers with overseas clients

Being self-employed in the UK and billing clients abroad does not change your Class 2 or Class 4 position; National Insurance follows where you live and work, not where your clients are. A UK sole trader invoicing US clients still reports the profit on Self Assessment. If you trade through a limited company and US clients request tax forms, our guide to Form W-8BEN-E explains what the company signs; directors of their own company build their record through salary rather than Class 2, as covered in our comparison of sole trader vs limited company.

Class 2 and your tax return

On your Self Assessment tax return, HMRC works out Class 4 from your profits automatically. Class 2 only appears if you choose to pay voluntarily. Your profit figure comes from your business income and expenses, so the quality of your invoicing directly determines your National Insurance position. Sole traders invoicing clients can follow our UK sole trader invoice guide.

Your National Insurance starts with an accurate profit figure, and that starts with your invoices. Create clean, numbered invoices with our free invoice generator, with no sign-up needed, and download them as PDFs for your Self Assessment records.
