How much tax does a self-employed barber pay

You are taxed on profit, not on takings

This is the bit that trips people up, and it is worth getting straight before anything else. HMRC does not care what went through the till. It cares what was left after the costs of running the chair.

Takings − the shop's cut − your costs = profit. Tax is worked out on the profit.

So a barber taking £52,000 a year, paying £6,900 in chair rent and another £3,000 on products, clippers and insurance, is taxed on £42,100. Not on £52,000. Getting your costs recorded properly is worth more than any clever planning.

The two things you pay

Income tax, on profit above your personal allowance of £12,570. And Class 4 National Insurance, which is 6% on profit between £12,570 and £50,270, then 2% on anything above that.

Class 2 National Insurance is no longer a compulsory charge. It stopped being mandatory in April 2024 and is now treated as paid to protect your record. If your profit is very low you can still pay it voluntarily to keep the year counting towards your state pension, which is usually worth doing.

The rates, if you live in England, Wales or Northern Ireland

The rates, if you live in Scotland

Scotland sets its own income tax bands, and there are six of them rather than three. This matters more than most barbers realise.

The line that catches people is the fourth one. In Scotland the 42% rate starts at £43,663. In the rest of the UK you are still paying 20% until £50,270. A barber having a very good year in Edinburgh keeps noticeably less of the top slice than one doing the same numbers in Manchester — on a £60,000 profit it is about £1,750 a year.

National Insurance is not devolved, so Class 4 is the same figure either side of the border.

What actually comes off before tax

Anything that is genuinely a cost of running the chair. For most barbers that is:

• Chair rent, or the shop's percentage
• Clippers, scissors, trimmers and their servicing
• Products, towels, gowns, barbicide, blades
• Public liability insurance
• Your accountant's fee
• Laundry, if you pay for it separately
• Card machine fees
• Trade body membership and training courses that keep existing skills current

What is not deductible is the stuff HMRC calls dual purpose — things you would have bought anyway. Ordinary clothes are the usual argument, and the usual loss. HMRC publishes the full list of allowable expenses and it is worth twenty minutes of your time once.

A worked example

Take that barber on £42,100 profit, outside Scotland:

• First £12,570 — no tax
• Remaining £29,530 at 20% — £5,906 income tax
• Class 4 on the same £29,530 at 6% — £1,772
• £7,678 owed, or about 18% of the profit

Over forty-six working weeks that is £167 a week to put by. The same barber in Scotland owes £7,764, which is £86 more.

The first-year trap: payments on account

This is the one that ruins people's Januarys, and almost nobody warns you about it.

If you owe more than £1,000, HMRC does not just want last year's tax. It also wants half of next year's, in advance, on the same day. Then the other half in July. So a first bill of £7,678 arrives as £11,517 due on 31 January — the year you owe, plus half again — and another £3,839 on 31 July.

It settles down after that, because from year two you are always paying ahead. But the first one is roughly half as large again as the number you were expecting, and it is why a barber who put by exactly the right amount still gets caught.

The dates

• 5 October — register as self-employed, by the October after the tax year you started in
• 31 January — file online and pay, for the tax year that ended the previous April. Plus the first payment on account
• 31 July — second payment on account

The tax year runs 6 April to 5 April, so you have roughly ten months between earning the money and paying the tax on it. That gap is exactly why weekly is the only sane way to save for it.

Put it by weekly, in a separate account

Work out your own number rather than using a rule of thumb, then move it on the same day you cash up. A separate account matters more than the amount: money sitting in your current account is money you will spend, and no amount of good intent survives a slow February.

If you want a starting point before you have any figures, a quarter of your profit put by weekly covers most barbers with room to spare. But your own number is better, and it takes a minute to work out.

Where this stops and an accountant starts

Everything above is the shape of it, not your return. It knows nothing about other income, a partner's allowance, a student loan, capital allowances on a big kit purchase, or the year you went VAT registered. A decent accountant costs a few hundred pounds, is itself deductible, and usually finds more than they charge in the first year.

The figures here are the published 2026/27 rates. Check them against HMRC before you act on anything — they change every April, and this is an estimate to plan with rather than advice.
