Class 2 NI for the Self-Employed 2026: Why Still Pay Voluntarily?
Class 2 NI is now optional if profits exceed £12,570. At just £3.45/week, here is why many self-employed people should still pay voluntarily to protect State Pension credits and Maternity Allowance.
When the government abolished the compulsory nature of Class 2 National Insurance in April 2024, many self-employed people breathed a sigh of relief -- £179.40 a year saved with no apparent downside. But for a significant number of sole traders, freelancers and partners, not paying Class 2 NI is a costly mistake that quietly erodes future State Pension entitlement and can strip access to Maternity Allowance entirely. The sums involved make it one of the best-value financial decisions available to the self-employed.
What changed in April 2024
Before 6 April 2024, every self-employed person with profits above the Small Profits Threshold (£6,725 in 2023/24) was required to pay Class 2 NI at a flat weekly rate. The Spring Budget 2023 announced the abolition of compulsory Class 2 NI from 6 April 2024 as a simplification measure.
From 2024/25 onwards:
- If your self-employed profits are above £12,570 (the Lower Profits Limit), you no longer have to pay Class 2 NI. However, you can choose to pay voluntarily.
- If your profits are between £6,725 and £12,570 (the Small Profits Threshold and the Lower Profits Limit), you get a free National Insurance credit -- a qualifying year without paying anything. This is sometimes called "treat as paid" Class 2 NI.
- If your profits are below £6,725, you can pay Class 2 NI voluntarily at £3.45/week to secure a qualifying year.
The rate for 2026/27 is £3.45 per week, giving a full qualifying year's cost of £179.40.

The full new State Pension in 2026/27 is £221.20/week (£11,502.40/year), requiring 35 qualifying years. Each qualifying year is worth one thirty-fifth of the full pension: approximately £6.32/week or £328.63/year for life.
Compare that to the cost of securing a qualifying year via Class 2:
- Cost of Class 2 NI: £179.40 for a full year
- State Pension value gained: £328.63/year for life (from State Pension age)
- Break-even: less than 7 months of drawing State Pension
Put another way: for every £1 spent on voluntary Class 2 NI, you will receive approximately £1.83/year in State Pension for life once you start drawing it. There is virtually no other financial product available that offers this return at this safety level.
For a 40-year-old self-employed person with 10 years to State Pension age, one missed qualifying year could cost them over £8,000 in total State Pension (25 years of drawing x £328.63/year). The £179.40 is trivially small by comparison.
Maternity Allowance: the other big reason to pay
Self-employed women who are pregnant or have recently given birth can claim Maternity Allowance from DWP -- but only if they meet the NI contribution test.
To qualify for the standard rate of £184.03/week for up to 39 weeks (the 2026/27 rate), you must:
- Have been self-employed (or employed) for at least 26 weeks in the 66-week test period before your baby's due date.
- Have paid (or be treated as having paid) Class 2 NI for at least 13 weeks in that 66-week period.
If you did not pay Class 2 NI voluntarily and your profits were above £12,570 (so no automatic credit applies), you may fail the contribution test and receive only £27/week (the minimum rate) instead of £184.03/week.
The difference: £184.03 vs £27/week = £157.03/week, over 39 weeks that is a potential loss of £6,124 in Maternity Allowance from not paying £179.40 in Class 2 NI.
Other contributory benefits protected by Class 2 NI
Beyond State Pension and Maternity Allowance, Class 2 NI also counts towards:
- New Style Employment and Support Allowance (ESA): a contributory benefit for people unable to work due to illness or disability. You need Class 2 NI payments in at least one of the last two full tax years before claiming.
- Bereavement Support Payment: a lump sum plus 18 monthly payments for surviving spouses or civil partners. The deceased must have paid sufficient NI (including Class 2) to qualify.
- New Style Jobseeker's Allowance: technically, Class 2 NI credits can contribute, though most self-employed people closing a business also have employee NI credits.
Who might reasonably not pay Class 2
There are cases where not paying Class 2 makes sense:
- Already have 35+ qualifying years: check your NI record. If you have 40 qualifying years from employment, there is nothing to gain from paying Class 2 NI.
- Not planning to stay in the UK: if you will not draw the UK State Pension (perhaps moving abroad permanently), the benefit may not apply.
- Very short self-employment period: if you are self-employed for only a few months and the year is already covered by employment NI from earlier in the year, you may already have a qualifying year.
- Auto-credited years: parents claiming Child Benefit for children under 12 receive automatic NI credits and may not need Class 2 to protect their qualifying year.
How to pay voluntarily via Self Assessment
Class 2 NI is collected via Self Assessment. On your return for 2026/27 (filed by 31 January 2028), you will see a prompt asking whether you want to pay voluntary Class 2 NI. Select yes and £179.40 (if you have a full year of self-employment) is added to your January payment on account bill.
You can also pay outstanding Class 2 NI for previous years -- up to six years back, or further using the State Pension top-up scheme if you are approaching pension age. Contact HMRC on 0300 200 3500 or use the online NI record service.

Frequently asked questions
Is Class 2 NI compulsory in 2026/27?
No. Since April 2024, Class 2 NI is no longer compulsory for self-employed people with profits above £12,570. But voluntarily paying it (£3.45/week) still counts as a qualifying year for State Pension and other contributory benefits.
What does Class 2 NI cost in 2026/27?
£3.45 per week, or £179.40 for a full qualifying year. It is collected via Self Assessment alongside your income tax and Class 4 NI bill.
What happens if I do not pay Class 2 NI?
You will not get a qualifying year towards your State Pension for that year (unless you have another source of credits, such as employment). Over a career this can reduce your State Pension by up to £11.02/week permanently.
How many qualifying years do I need for the full new State Pension?
35 qualifying years. You need at least 10 qualifying years to receive any State Pension at all.
Does paying Class 2 NI entitle me to Maternity Allowance?
Yes. Self-employed women who have paid Class 2 NI (or been treated as paying it) for at least 13 weeks in the 66-week test period can claim Maternity Allowance of £184.03/week for up to 39 weeks.
What if my profits are below £12,570?
If your profits are between £6,725 (Small Profits Threshold) and £12,570, you get Class 2 NI credits automatically without paying -- giving you a qualifying year for free. Below £6,725, you can pay Class 2 voluntarily at £3.45/week.
Can I pay voluntary Class 3 NI instead of Class 2?
Yes, but Class 3 costs £17.45/week (2026/27) -- more than five times the cost of Class 2. Self-employed people eligible for Class 2 should always use Class 2 to fill gaps, not Class 3.
What other benefits does Class 2 NI support?
Class 2 NI counts towards contributory Employment and Support Allowance (New Style ESA) and bereavement benefits (e.g. Bereavement Support Payment), in addition to State Pension and Maternity Allowance.
How do I pay Class 2 NI voluntarily?
Simply complete your Self Assessment return as normal. The system will ask whether you want to pay Class 2 NI. Select yes and the £179.40 (full year) will be added to your January tax bill.
Can I fill old gaps with Class 2 NI?
Yes -- you can pay voluntary Class 2 NI for gaps in your self-employment record going back six years (or further in some cases via the State Pension top-up scheme). Contact HMRC or the Future Pension Centre to check your NI record and identify gaps worth filling.
