How to Register as a Sole Trader: The Complete UK Guide

Quick answer: To register as a sole trader, tell HMRC you're self-employed by registering for Self Assessment at gov.uk. You must register if you earned over £1,000 -for more about this check what a side hustle is and how would HMRC treat your income over £1000 in 2026- in a tax year, and the deadline is 5 October in your second tax year. Registration is free and you'll receive a Unique Taxpayer Reference (UTR).

Here's something most people don't realise: you can legally start trading tomorrow without filling in a single form. The sole trader model is the UK's most popular business structure precisely because it's that simple. But "simple" doesn't mean "no rules"-and getting the timing of your HMRC registration wrong can land you with a penalty before you've even made your first sale.

If you're a freelancer, contractor, plumber, hairdresser, or someone who's just started selling on Etsy at the weekend, this guide is for you. We'll walk through exactly how to register as a sole trader, when you actually need to do it, how much tax you'll pay, and the questions that keep new business owners up at night-from bounce back loans to business bank accounts.

Key Takeaways

• You register as a sole trader by registering for Self Assessment with HMRC - there's no separate "sole trader" form.
• The £1,000 rule matters: you must register if you earned more than £1,000 from self-employment in a tax year.
• The deadline is 5 October in your business's second tax year. Miss it and you risk a penalty.
• Registration is free and takes a few hours, though your UTR can take up to 15 days to arrive.
• You keep all profits after tax, but you're personally liable for all business debts—there's no legal separation between you and your business.
• You can be employed and a sole trader at the same time, which is common when starting out.

What is a sole trader?

A sole trader is a self-employed person who owns and runs their business as an individual. It's the simplest business structure in the UK, which is why most people choose it when first starting out.

You are the business, meaning there's no legal separation between you and the work you do. According to GOV.UK, as a sole trader you "work for yourself, are classed as self-employed, and make all the business decisions."

A sole trader business in the UK can cover almost any trade. You'll find plumbers, decorators, hairdressers, consultants, online sellers, and freelancers all operating this way. You keep all the profits after tax-but you also shoulder all the responsibility.

What is the difference between self-employed and sole trader?

People use these terms interchangeably, but they're not quite the same thing.

• Self-employed describes your tax status-it means you're responsible for paying your own tax, rather than having an employer deduct it through PAYE.
• Sole trader describes your business structure-it's how your business is legally set up.

Put simply: all sole traders are self-employed, but not all self-employed people are sole traders (some run limited companies or partnerships instead). When you register as a sole trader, you're really doing two things at once: confirming your business structure and telling HMRC you'll handle your own tax.

Does a sole trader have a company registration number?

No. A company registration number (CRN) is issued by Companies House only to limited companies and LLPs. As a sole trader, you don't register with Companies House at all-so you won't have a CRN.

What you will get instead is a 10-digit Unique Taxpayer Reference (UTR) from HMRC once you register for Self Assessment. Keep this safe; you'll need it every time you deal with the taxman.

Do I need to register as a sole trader?

Yes, if you earned more than £1,000 from self-employment in a tax year (6 April to 5 April), you must register. This is HMRC's golden rule.

You should also register if you need to:

• Prove you're self-employed (for example, to claim Tax-Free Childcare).
• Make voluntary Class 2 National Insurance payments to protect your v.
• Register as a subcontractor under the Construction Industry Scheme (CIS).

Earning under £1,000? You're covered by the trading allowance and don't need to register, though you can choose to register early if you'd like to.

Can I be a sole trader and employed at the same time?

Yes, you can be both employed and a sole trader simultaneously-and it's incredibly common. Plenty of people build a side business while keeping their day job.

Your employer will continue deducting tax through PAYE on your salary. Meanwhile, you'll complete a Self Assessment tax return each year and pay tax on your business profits on top. One tip: check your employment contract for any conflict-of-interest clauses before you start.

For example, you work full-time as a graphic designer for a marketing agency and receive your salary through PAYE. However, you are also passionate about illustration and take on freelance commissions in your spare time. At the end of the tax year, you complete a Self Assessment tax return to report her freelance earnings, while your agency handles your regular employment taxes. By staying organised and keeping track of your business income and expenses, you can balance both roles successfully without any tax complications.

How to register as a sole trader in the UK: a step-by-step guide

Ready to set up as a sole trader? Here's how to register, step by step.

Step 1: Check that being a sole trader is right for you

Before anything else, weigh up whether the sole trader structure suits you. Remember, you'll have unlimited liability, meaning your personal assets could be at risk if the business runs into debt. If that worries you, a limited company might be worth considering (more on that below).

Step 2: Choose your business name

You can trade under your own name or pick a business name. If you choose a name, the rules are clear. Your sole trader name must not:

• Include "limited", "Ltd", "LLP", or "plc".
• Be offensive.
• Be too similar to another company's trademarked name (check the trademark register first).

Whatever name you choose, you must include both your name and your business name on official paperwork like invoices and letters. To find out more about business names, check our guide.

Step 3: Register for Self Assessment with HMRC

This is the actual registration. Head to gov.uk and register for Self Assessment as a sole trader. You can do this through your Government Gateway account (or create one if you don't have it).

You'll need your National Insurance number, and you'll be asked for your name, address, and the nature of your business.

Step 4: Get your UTR and keep records

Once registered, HMRC sends you a Unique Taxpayer Reference (UTR). According to gov.uk, this can take up to 15 days to arrive. After that, you'll file a Self Assessment tax return each year and keep accurate records of your income and expenses (HMRC recommends keeping these for at least five years, see what documents you need to keep as a self employed.)

Important deadline: You must register by 5 October in your business's second tax year. Register late, and you could face a penalty.

Can a sole trader be VAT registered?

Yes, a sole trader can be VAT registered. Here's what you need to know.

You must register for VAT if your taxable turnover exceeds £90,000 in any 12-month period (this threshold rose from £85,000 on 1 April 2024). Below that, registration is voluntary.

Can you be VAT registered as a sole trader voluntarily? Absolutely. Some sole traders register early because their clients prefer dealing with VAT-registered businesses, or because it lets them reclaim VAT.

Can I claim VAT back as a sole trader? Yes—once you're VAT registered, you can reclaim VAT on eligible business purchases. The trade-off is extra admin, since you'll need to file regular VAT returns.

Do I need a business bank account as a sole trader?

Legally, no—a sole trader isn't required to have a separate business bank account, because you and your business are the same legal entity.

In practice, though? It's strongly recommended. Mixing personal and business money makes your Self Assessment a nightmare to untangle. A dedicated account keeps your records clean and your sanity intact. One word of warning: many personal bank accounts ban business use in their terms, so check before relying on yours.

What insurance does a sole trader need?

There's no single answer here—the insurance you need depends on your trade. But here's a rundown of the common types.

• Public liability insurance: Do you need it? It's not a legal requirement, but if you interact with the public or visit client sites, it's highly advisable. It covers claims if someone is injured or their property is damaged because of your work.
• Professional indemnity insurance: Worth having if you give advice or provide a professional service.
• Employers' liability insurance: Do you need it as a sole trader? Only if you employ staff—and then it's a legal requirement (you can be fined for not having it).

Do I need business insurance as a sole trader? It's rarely legally mandatory unless you have employees, but it protects you from claims that could otherwise wipe out your personal assets. Given your unlimited liability, that protection is worth serious thought.

Can a sole trader have employees?

Yes—the name is misleading. Being a "sole" trader means you're the sole owner, not that you have to work alone.

If you take on staff, you'll need to:

• Register as an employer with HMRC before their first payday.
• Set up a PAYE payroll scheme.
• Take out employers' liability insurance.
• Provide a workplace pension to eligible employees.

How to write off a bounce back loan as a sole trader

This is a tough one, so let's be straight with you. Because a sole trader has unlimited liability, a Bounce Back Loan (BBL) is treated as your personal debt. There's no company to shield you.

Will bounce back loans be written off for sole traders? Not easily. According to The Insolvency Experts, "the only way you can write off a self-employed sole trader's BBL debt is to enter a formal insolvency process."

That means your realistic options are:

• An Individual Voluntary Arrangement (IVA): a formal agreement to repay what you can afford over a set period, with the remainder written off.
• Bankruptcy: a last resort that clears the debt but carries serious consequences for your finances and assets.

If you're struggling with BBL repayments, speak to a qualified insolvency adviser before making any decisions. This isn't something to face alone.

How to close a business as a sole trader in the UK

Winding down? Closing a sole trader business is mercifully straightforward compared to dissolving a company. You'll need to:

• Tell HMRC you've stopped being self-employed.
• File a final Self Assessment tax return for your last trading period.
• Pay any outstanding tax you owe.
• Cancel your VAT registration if you were registered.
• Close down PAYE if you employed staff.

Do I need an accountant as a sole trader?

You're not legally required to have one. But with Making Tax Digital for Income Tax arriving from April 2026—bringing quarterly digital updates for sole traders earning over £50,000—the admin is only getting heavier.

A good accountant saves you time, helps you claim every allowable expense, and keeps you on the right side of HMRC's deadlines. For many sole traders, the cost pays for itself in deductions found and penalties avoided.

FAQ on Sole Trader in 2026

Should I be a sole trader or limited company?

This is the big question, so let's break it down. Both structures have their place—the right choice depends on your priorities.

Choose a sole trader structure if simplicity, privacy, and low cost matter most—especially when you're just starting out and testing the waters.

Choose a limited company if protecting your personal assets and tax efficiency are higher priorities, particularly once your profits grow.

Can a sole trader be a limited company?

Not at the same time—they're separate structures. But you can absolutely start as a sole trader and switch later.

How to change from sole trader to limited company

When your business is stable and growing, you can transition by:

• Registering (incorporating) a limited company with Companies House.
• Telling HMRC you've stopped being self-employed.
• Transferring your business assets to the new company.
• Setting up a business bank account in the company's name.

Many business owners make this move once profits reach a level where the tax savings outweigh the extra admin.

Take a look at Debitam`s thorough guide to help you change from sole trader to limited company for more.

How much tax does a sole trader pay?

As a sole trader, you pay Income Tax on your profits (income minus allowable expenses) plus National Insurance contributions. You don't pay Corporation Tax—that's for limited companies.

Here are the current Income Tax bands for England, Wales, and Northern Ireland (Scotland has different rates):

For National Insurance, here's how it breaks down:

Your tax bill is due by 31 January following the end of the tax year. You may also need to make "payments on account"—advance payments towards next year's bill.

How do I pay myself as a sole trader?

Here's where it gets refreshingly simple. As a sole trader, there's no payroll and no separate salary. You simply take money out of the business whenever you need it—these are called "drawings." Just remember: drawings aren't a business expense, and you're taxed on your profits, not on what you withdraw.

You can also check how heavily regulated paying yourself as a limited company director to help you decide what model of business is for you.

How do I invoice as a sole trader?

Your invoices should include your name, your business name (if you have one), the date, a description of the work, the amount due, and your payment terms. If you're VAT registered, you'll also need to show your VAT number and the VAT charged.

As a complicated subject, many small business owners incline to think of VAT as a business killer, check if you`d be on a similar situation.

What expenses can I claim as a sole trader?

Claiming allowable expenses reduces your taxable profit, which means a smaller tax bill. Here's a quick guide to what counts.

Keep every receipt and bank statement to back up your claims. As Debitam notes from filing thousands of Self Assessment returns, good record-keeping is the difference between a smooth tax season and a stressful one.

Bear in mind £312 working from tax relief is no more since April 2026.

How long does it take to register as a sole trader?

The initial setup takes a few hours, but your UTR can take up to 15 days to arrive by post, according to HSBC. Register well before your 5 October deadline to be safe.

Does it cost anything to register as a sole trader?

No—registering with HMRC is completely free. Your only costs come from running the business itself, like insurance or professional advice.

Do I need to be VAT registered as a sole trader?

Only if your taxable turnover exceeds £90,000 in a 12-month period. Below that, it's your choice.

Can I register if I'm only working part-time?

Yes. The £1,000 earnings threshold applies regardless of whether your self-employment is full-time or a side hustle.

What happens if I register for sole trader late?

You may receive a penalty from HMRC. The deadline is 5 October in your second tax year, so don't leave it.

Do I need a business bank account as a sole trader?

It's not legally required, but separating business and personal finances makes managing your money and filing your tax return far easier. For a more thorough response, check if you need a business bank account as a sole trader and what banks in the UK are best for you.
