National Insurance for Self-Employed Beauty Workers
National Insurance is the tax that nobody really understands but everybody pays. As a self-employed beauty worker, you pay two types: Class 2 (a small flat rate that gives you State Pension credits) and Class 4 (a percentage of your profits). This guide explains how both work, what they cost you, and why they matter for your pension and benefits.
Quick rule of thumb: budget for NI on top of your Income Tax - it adds roughly 6-9% to your tax bill on profits between £12,570 and £50,270.
The two types of NI you pay
Class 2 National Insurance
| Detail | Amount (2025/26) |
|---|---|
| Rate | £3.50 per week (2025-26 rate) |
| Annual cost | £182 |
| When you pay it | Through your Self-Assessment tax return |
| What it gives you | Qualifying year for State Pension and certain benefits |
Class 2 NI is a flat weekly charge. It's small, but it's important because it counts towards your State Pension entitlement. You need 35 qualifying years to get the full new State Pension (currently £221.20 per week). Each year you pay Class 2 NI counts as a qualifying year.
If your profits are below the Small Profits Threshold (£6,725 per year): you don't have to pay Class 2 NI, but you can choose to pay it voluntarily. We'd strongly recommend doing this - £182 a year is a tiny price to protect your pension record.
Tip for new starters: Even if you earn very little in your first year while building up clients, pay the voluntary Class 2 NI (£3.50 per week). It protects your State Pension record and keeps you eligible for Maternity Allowance. Skipping it to save £182 could cost you thousands in lost pension and benefits over your lifetime.
Class 4 National Insurance
| Detail | Amount (2025/26) |
|---|---|
| Rate (main) | 6% on profits between £12,570 and £50,270 |
| Rate (additional) | 2% on profits above £50,270 |
| When you pay it | Through your Self-Assessment tax return |
| What it gives you | Nothing directly - it doesn't count towards your pension or benefits |
Class 4 NI is the one that actually costs money. It's calculated on your taxable profits - the same figure used for Income Tax.
Example - beauty therapist with £28,000 profit:
| Calculation | Amount |
|---|---|
| Profits | £28,000 |
| Class 4 threshold | £12,570 |
| Profits subject to Class 4 NI | £15,430 |
| Class 4 NI at 6% | £926 |
| Class 2 NI | £182 (2025-26 rate) |
| Total NI | £1,105 |
That's on top of your Income Tax. At this profit level, your Income Tax would be about £3,086, so your total tax + NI is around £4,191.
How NI is calculated at different earnings levels
Here's what you'd pay at typical beauty earnings (2025/26 rates, assuming no other income):
| Annual profit | Income Tax | Class 2 NI | Class 4 NI | Total tax + NI | Take-home |
|---|---|---|---|---|---|
| £15,000 | £486 | £182 | £146 | £811 | £14,189 |
| £20,000 | £1,486 | £182 | £446 | £2,111 | £17,889 |
| £25,000 | £2,486 | £182 | £746 | £3,411 | £21,589 |
| £30,000 | £3,486 | £182 | £1,046 | £4,711 | £25,289 |
| £35,000 | £4,486 | £182 | £1,346 | £6,011 | £28,989 |
| £40,000 | £5,486 | £182 | £1,646 | £7,311 | £32,689 |
| £45,000 | £6,486 | £182 | £1,946 | £8,611 | £36,389 |
| £50,000 | £7,486 | £182 | £2,246 | £9,911 | £40,089 |
These figures assume you have no other income and use the full personal allowance (£12,570).
How NI affects your State Pension
Your State Pension is based on your National Insurance record. Here's what matters:
- You need 35 qualifying years for the full new State Pension (£221.20/week in 2025/26)
- You need at least 10 qualifying years to get any State Pension at all
- Class 2 NI gives you a qualifying year
- Class 4 NI does NOT give you a qualifying year (it's purely a tax - you get nothing back from it)
- If you're employed and self-employed, your employed NI contributions (Class 1) also count
Check your pension record
You can check how many qualifying years you have at gov.uk/check-state-pension. This shows:
- How many years you've built up
- Any gaps in your record
- Your projected State Pension amount
- When you'll reach State Pension age
Do this today. It takes 5 minutes and it's free. If you have gaps, you might be able to fill them (see below).
Tip for new starters: Check your State Pension forecast at gov.uk/check-state-pension before you file your first tax return. If you had gaps before going self-employed - from time off, travelling, or low-paid work - you may be able to fill them cheaply with voluntary Class 2 contributions at just £3.50 per week per missing year.
Filling gaps in your NI record
If you've had years where you didn't pay enough NI - because you weren't working, were earning below the threshold, or were abroad - you may have gaps in your record.
You can fill gaps by making voluntary NI contributions. You can usually go back up to 6 years (and in some cases further, under transitional rules).
Cost of voluntary Class 2 NI: £3.50/week (2025-26 rate) (2025/26 rate) - so about £182 to fill one year. Cost of voluntary Class 3 NI: £17.45/week (2025/26 rate) - about £907 for one year. This is the rate for people who aren't self-employed.
If you're self-employed, voluntary Class 2 is much cheaper than Class 3 for building your pension record. This is one of the genuine perks of being self-employed.
Is it worth filling gaps? Usually yes. Each additional qualifying year increases your State Pension by about £6.32/week (£329/year). Paying £182 to gain £329/year for the rest of your life after State Pension age is an excellent return.
Contact the Future Pension Centre (0800 731 0175) to check whether filling a specific gap would increase your pension.
NI credits you might be entitled to
Some situations give you NI credits automatically - meaning you get qualifying years without paying:
| Situation | Credit type |
|---|---|
| Claiming Child Benefit for a child under 12 | Class 3 NI credit (automatic) |
| Maternity Allowance / Statutory Maternity Pay | Class 3 NI credit |
| Carer's Allowance | Class 3 NI credit |
| Universal Credit | Class 3 NI credit (usually) |
| Jury service | Class 3 NI credit |
| Approved foster carers | Class 3 NI credit (needs to be claimed) |
If you've been on maternity leave or caring for children, check that you've been getting NI credits. If you claimed Child Benefit (even if you didn't receive the money because of the High Income Child Benefit Charge), you should have credits.
Employed AND self-employed: do you pay twice?
Yes, but there's a cap.
If you have a job where you pay Class 1 NI (employee contributions) AND you're self-employed paying Class 2 and Class 4 NI, you pay both. However, there's an annual maximum amount of NI you can pay.
The annual maximum ensures you don't pay more than someone who earns the same total amount from a single source. If you overpay, HMRC refunds the excess after you file your return.
Example: You work part-time at a salon earning £15,000 (PAYE) and do mobile beauty work earning £12,000 profit (self-employed).
- Your employer deducts Class 1 NI from your salary
- You pay Class 2 NI (£182, 2025-26 rate) and Class 4 NI on your self-employed profits through Self-Assessment
- If the total exceeds the annual maximum, HMRC adjusts it
In practice, most beauty workers with combined employment + self-employment earnings under £50,000 won't hit the cap. You'll pay both, and it'll feel like a lot, but it's correct.
NI and maternity
Self-employed women can claim Maternity Allowance (not Statutory Maternity Pay - that's for employees). To qualify, you generally need to have:
- Been registered as self-employed for at least 26 weeks in the 66 weeks before your due date
- Paid Class 2 NI for at least 13 of those weeks
Maternity Allowance rate (2025/26): up to £184.03/week for up to 39 weeks.
This is why paying Class 2 NI matters even if your profits are low. If you don't pay it, you could lose your entitlement to Maternity Allowance.
You apply through Jobcentre Plus or online at gov.uk/maternity-allowance.
Common questions
"Do I pay NI on my turnover or my profit?" Profit. After deducting all your allowable business expenses. This is the same figure used for Income Tax.
"I earn very little - do I still need to pay NI?" If your profits are below £6,725, you don't have to pay Class 2, and you won't pay Class 4 (it only kicks in at £12,570). But we'd recommend paying Class 2 voluntarily to protect your pension.
"Does NI affect my personal allowance?" No. NI and Income Tax are calculated separately. Your personal allowance (£12,570) only affects Income Tax, not NI. Class 4 NI starts at the same threshold (£12,570) but that's a coincidence of current rates, not a shared allowance.
"I'm over State Pension age - do I still pay NI?" No. Once you reach State Pension age, you stop paying Class 2 and Class 4 NI. You still pay Income Tax on your profits, though.
"I've heard NI is being reformed - what's changing?" There have been discussions about merging NI with Income Tax or simplifying the system. As of 2025/26, the system described in this guide is current. We'll update this guide if changes are announced.
Summary: what you pay and what you get
| NI class | Who pays it | Rate | What you get |
|---|---|---|---|
| Class 2 | Self-employed | £3.50/week (2025-26 rate) | State Pension qualifying year, Maternity Allowance eligibility |
| Class 4 | Self-employed | 6% on £12,570-£50,270; 2% above £50,270 | Nothing directly |
| Class 1 | Employees (for comparison) | 8% on £12,570-£50,270; 2% above | State Pension, Maternity Pay, Jobseeker's Allowance |
Self-employed people get less from their NI than employees do. Class 4 NI doesn't count for anything - it's effectively just extra tax with a different name. The valuable bit is Class 2, which is cheap.
What to do next
- Check your State Pension forecast at gov.uk/check-state-pension - do this today
