If you are thinking about working for yourself, becoming a sole trader is one of the simplest ways to start. It is the most common business structure in the UK, used by everyone from plumbers and hairdressers to freelance designers and online sellers.
A sole trader is a self-employed person who owns and runs their business as an individual. There is no legal split between you and the business, which keeps things simple but also means you carry full responsibility for it.
This guide from the team at Digi Accounting explains what a sole trader is, the pros and cons, how to register, and the tax and admin duties involved. By the end, you should have a clear idea of whether this structure suits you.
Important Summary
Here are the main points:
- A sole trader is a self-employed individual who owns and runs their own business.
- You keep all profits after tax, but you are personally responsible for any debts.
- Setup is quick and cheap, with far less admin than a limited company.
- You pay income tax and National Insurance on your profits through Self Assessment.
- You can change to a limited company later if your business grows.
What Is a Sole Trader?
A sole trader runs their business on their own. Unlike a limited company, the business is not a separate legal entity, so in the eyes of the law you and your business are the same.
This is often summed up by the phrase “you are the business”. You make all the decisions, you keep the profits, and you take on all the risk.
Because there is no legal separation, a sole trader has unlimited liability. If the business runs up debts it cannot pay, your personal assets, such as your savings or even your home, could be at risk.
Setting up is straightforward. You register with HM Revenue and Customs (HMRC) as self-employed, rather than with Companies House, and you report your income each year through a Self Assessment tax return.
Key Features of a Sole Trader
The sole trader model has a few defining features:
- Full control: You make every business decision yourself.
- Simple setup: Minimal paperwork and low start-up costs.
- Personal liability: You are responsible for all business debts.
- You keep the profits: After tax, the money the business makes is yours.
- Taxed as an individual: You pay income tax and National Insurance on profits.
- Less admin: Fewer ongoing reporting duties than a limited company.
- Flexible branding: You can trade under your own name or a business name.
Examples of Sole Traders
The sole trader model suits many lines of work, and it is especially popular with people offering a service directly to customers. Common examples include:
- Plumbers, electricians, builders and decorators
- Hairdressers and mobile beauticians
- Freelance writers, graphic designers and web developers
- Marketing consultants and bookkeepers
- Personal trainers, gardeners and photographers
- Taxi drivers and tradespeople
- Market traders and people selling handmade goods online
Sole traders make up a large share of UK business. Recent figures suggest there are around three million sole proprietorships, making it the single most common way to run a business in the country.
Advantages of Being a Sole Trader
There are good reasons why so many people choose this route. The benefits centre on speed, control and simplicity.
Quick and Easy Setup
You can start trading almost straight away. There is no need to wait for approval from Companies House, and you do not have to register a company or pay a formation fee.
In most cases, registering for Self Assessment with HMRC is all you need to do. This makes the sole trader route ideal for testing a business idea or turning a side project into something bigger.
Full Control and Autonomy
As a sole trader, you answer to no one but yourself. There are no directors to consult, no board meetings to hold and no shareholders to satisfy.
This means you can shape the business around your own goals. From daily tasks to long-term plans, every decision is yours to make.
Flexibility
Having full control gives you the freedom to work on your own terms. You can change direction quickly, take on the work you want, and respond fast when new opportunities come up.
For many people, this flexibility is one of the biggest draws of self-employment. It lets you run the business in a way that fits your life.
Less Admin and Simpler Accounting
Sole traders face far fewer reporting duties than limited companies. There are no annual accounts to file at Companies House and no confirmation statement to submit.
Your main duties are keeping good records and filing one Self Assessment tax return each year. This lighter workload saves time and often reduces accountancy costs too.
Simpler Taxation
Your tax position is more straightforward as a sole trader. You pay income tax on your business profits as part of your personal income, all through a single annual return.
This is simpler than a limited company, where the company pays Corporation Tax and the owner is taxed separately on any salary and dividends. Fewer moving parts means fewer chances to slip up.
Keeping All Your Profits
After you have paid your tax, all the profit your business makes belongs to you. You are free to spend it, save it or put it back into the business.
This is different from a limited company, where profits belong to the company and you must follow set rules to take money out. As a sole trader, the money is simply yours.
Financial Privacy
A limited company must put certain details on the public record, including its accounts and information about its directors. A sole trader does not.
This means your financial information stays private. For people who value discretion about how their business is doing, this is a real plus.
Disadvantages of Being a Sole Trader
The sole trader model is not right for everyone. It is important to weigh up the drawbacks before you decide.
Unlimited Liability and Financial Risk
The biggest downside is unlimited liability. Because you and the business are the same in law, you are personally responsible for every debt the business takes on.
If things go wrong and the business cannot pay what it owes, creditors can pursue your personal assets. A limited company, by contrast, caps the owner’s risk at the amount they have put in.
You can reduce some of this risk with the right business insurance, but cover will not protect your personal assets against business debt.
You Could Pay More Tax
While the tax is simpler, sole traders do not get the same planning options as limited companies. As your profits rise, you may find you pay more tax than you would through a company structure.
For higher earners, this can make a real difference. If your business is growing, it may be worth checking whether incorporating would leave you better off.
Harder to Raise Finance
Lenders often see sole traders as higher risk than limited companies. This can make it harder to borrow money or secure investment, and you may face higher interest rates.
You also cannot sell shares to raise funds, since a sole trader has no shares to issue. That limits how you can bring money into the business.
Managing Everything Yourself
When you are a sole trader, the buck stops with you. You handle the work, the admin, the marketing, the invoicing and the tax, often all at once.
This can be rewarding, but it is also demanding. Taking time off can be difficult, because there may be no one else to keep things running while you are away.
Limits on Growth
Relying on one person can cap how far the business can grow. Without partners, directors or outside investment, scaling up is harder.
You can still take on staff or work with freelancers, but the structure is built around a single owner. Many growing businesses eventually move to a company model for this reason.
How to Set Up as a Sole Trader
Getting started is simpler than most people expect. Here are the main steps to follow.
Check the Sole Trader Structure Suits You
Before anything else, make sure this structure fits your plans. Think about your appetite for risk, since you will be personally liable, and whether you expect to grow quickly or bring in partners.
If you want to keep things simple and start fast, sole trader status often works well. If you need investment or want to protect personal assets, a limited company may suit you better.
Choose a Business Name
You can trade under your own name or pick a business name. If you choose a business name, there are a few rules to follow.
Your name cannot be offensive or misleading, and it must not suggest a link to the government or local authority. It also cannot include terms like “limited”, “Ltd”, “LLP” or “plc”, and it should not copy an existing trade mark. You can check existing trade marks through the Intellectual Property Office.
You must include your own name, and the business name if you use one, on official paperwork such as invoices and letters.
Register with HMRC
To work as a sole trader, you need to tell HMRC you are self-employed so you can pay income tax and National Insurance on your profits. You can do this online through the government website.
Once registered, you will receive a Unique Taxpayer Reference (UTR), which you use to file your tax return. You can find the official steps on the GOV.UK guide to setting up as a sole trader.
Registration Deadlines
You must register if you earned more than £1,000 from self-employment in a tax year, which runs from 6 April to 5 April.
The deadline is 5 October in your business’s second tax year. For example, if you start trading in the 2025/26 tax year, you must register by 5 October 2026. If you miss the deadline, you could face a penalty, so it pays to register promptly.
Set Up a Separate Bank Account
A sole trader is not legally required to have a separate business bank account, but it is strongly advised. Keeping business and personal money apart makes your record keeping far easier.
It also makes filling in your tax return simpler and clearer, and it helps you see how the business is really doing. Many high street and online banks offer accounts aimed at sole traders.
Check Your Insurance Needs
Depending on your work, you may need some form of business insurance. Common types include public liability cover, professional indemnity cover and insurance for tools or equipment.
If you employ anyone other than close family, employers’ liability insurance is a legal requirement. It is worth reviewing your risks early and getting the right cover in place.
Check for Licences or Permits
Some types of work need a licence or permit before you can start. This is common in regulated sectors such as food, childcare, taxis and street trading.
Check with your local authority or the relevant body to see whether your work needs approval. Trading without a required licence can lead to fines or worse.
Tax Responsibilities of a Sole Trader
Tax is where sole traders have the most to keep on top of. The duties are manageable, but you need to understand them to stay compliant and avoid penalties.
Income Tax Rates and Bands
As a sole trader, you pay income tax on your business profits, which count as part of your personal income. You only pay tax on profit, not on your total income, so your allowable expenses reduce the bill.
For the current tax year in England and Wales, the income tax rates are:
- Up to £12,570: 0% (Personal Allowance)
- £12,571 to £50,270: 20% (Basic Rate)
- £50,271 to £125,140: 40% (Higher Rate)
- Over £125,140: 45% (Additional Rate)
These thresholds are frozen for several years, so more people may move into higher bands over time. You can check the latest figures on the GOV.UK income tax rates page.
Self-Assessment Tax Returns
Sole traders report their income through the Self Assessment system. You must file a return for each tax year, showing your income, expenses and profit, then pay any tax due.
The key dates for a tax year are:
- Register by 5 October if you need to file for the first time.
- Submit a paper return by 31 October.
- Submit an online return by 31 January.
- Pay any tax owed by 31 January.
Filing late or paying late can lead to penalties and interest, so it helps to prepare early rather than leaving it to the last minute.
National Insurance Contributions
On top of income tax, sole traders pay National Insurance contributions (NICs), which count towards benefits such as the State Pension. Self-employed people may pay two classes.
Here is how they work for the current tax year:
- Class 2: If your profits are above the small profits threshold of £6,725, you are treated as having paid Class 2 and build up your National Insurance record without making a payment. If your profits are below that, you can pay Class 2 voluntarily to protect your record.
- Class 4: You pay 6% on profits between £12,570 and £50,270, then 2% on profits above £50,270.
You can see the current rates and thresholds on HMRC’s website.
Payments on Account
Many sole traders have to make “payments on account”. These are advance payments towards your next tax bill, based on what you owed the previous year.
They are usually due in two instalments, on 31 January and 31 July. The system can catch people out in their first year, because you may pay your first full bill and an advance payment at the same time. Setting money aside helps you avoid a nasty surprise.
Registering for VAT
You must register for VAT if your taxable turnover goes over the VAT threshold, which is currently £90,000 in a rolling 12-month period. You can also register voluntarily below that level if it suits your business.
Once registered, you charge VAT on your sales, complete regular VAT returns and pay what you owe to HMRC. Keep an eye on your turnover so you do not miss the point at which you need to register.
Allowable Business Expenses
You can deduct legitimate business costs from your income, which lowers your profit and your tax bill. Common allowable expenses include:
- Office and admin costs, such as stationery, software, phone and internet bills
- Travel costs, including fuel, train fares and vehicle running costs for business trips
- Staff costs, such as wages and subcontractor payments
- Marketing and advertising, including your website and online ads
- Professional fees, such as accountancy and legal advice
If you work from home, you can claim a fair share of costs like rent, council tax and utilities. You cannot claim for personal use, so you must work out the business portion.
Budgeting for Your Tax Bill
Because tax is not taken at source, you are responsible for setting money aside to pay it. It is easy to spend money that is really owed to HMRC, then struggle when the bill arrives.
A good habit is to put a percentage of every payment you receive into a separate savings account. That way, the money is ready when your tax and National Insurance fall due in January.
Making Tax Digital for Income Tax
The way sole traders report tax is changing. Making Tax Digital (MTD) for Income Tax is being rolled out, starting with sole traders and landlords who have qualifying income above £50,000.
Under MTD, you keep digital records and send updates to HMRC through approved software during the year, rather than filing one annual return. Lower income thresholds will be brought in over the following years, so it is wise to prepare early and choose suitable software.
Other Ongoing Responsibilities
Beyond tax, running a sole trader business comes with a handful of ongoing duties. None are especially heavy, but they matter.
Keeping Accurate Financial Records
You must keep records that give a true and fair picture of your business, including all your sales and expenses. Unlike a company, there is no set format you have to follow.
Good records make your tax return far easier and help you spot how the business is performing. A spreadsheet or accounting software, plus copies of receipts and invoices, will usually do the job.
Invoicing and Managing Payments
Sending clear invoices and chasing late payments is part of running the business. Steady cash flow keeps you able to pay your own bills and tax on time.
Your invoices should include your name, your business name if you use one, and the details of what you are charging for. Staying on top of who owes you money protects the health of your business.
Business Insurance
The right insurance protects you against things that could otherwise wipe out your business. The cover you need depends on your work.
Public liability insurance is common for anyone dealing with the public, while professional indemnity cover suits those giving advice or a professional service. If you employ staff, employers’ liability insurance is a legal must unless you only employ close family.
Employing Staff
Being a sole trader does not mean you have to work alone. You can take on employees, but doing so brings extra duties.
You must register with HMRC as an employer and run a PAYE payroll, deducting income tax and National Insurance from your staff’s pay. You will also need employment contracts, and you may have to provide a workplace pension and pay employer’s National Insurance.
Data Protection and Regulations
If you handle personal information about customers, you must follow data protection law. Failing to do so can lead to serious fines.
You also need to meet any rules that apply to your trade, including health and safety standards and any industry-specific licences. Staying compliant keeps your business on the right side of the law.
Sole Trader vs Other Business Structures
Choosing how to run your business is an important decision. It helps to see how the sole trader model compares with the main alternatives.
Sole Trader vs Limited Company
A limited company is a separate legal entity from its owners, which changes how risk, tax and admin work. Here are the main differences:
- Setup: A sole trader is quick, free and simple. A company involves registering at Companies House and following more formalities.
- Liability: A sole trader has unlimited liability. A company offers limited liability, capping the owner’s risk at what they invest.
- Tax: A sole trader pays income tax and Class 4 NICs on profit. A company pays Corporation Tax, and directors are taxed on salary and dividends.
- Privacy: A sole trader keeps details private. A company must publish accounts and director details.
- Funding: A company can issue shares and often finds it easier to raise money than a sole trader.
- Continuity: A sole trader business ends if the owner stops. A company can continue under new ownership.
Sole Trader vs Partnership
A partnership involves two or more people running a business together and sharing the responsibility, profits and risk. It suits those who want to go into business with someone else.
A sole trader, by contrast, works alone and keeps full control. If you want shared decision-making and pooled resources, a partnership may fit better, though it also means shared liability.
Is Becoming a Sole Trader Right for You?
Becoming a sole trader gives you simplicity, control and low start-up costs. In return, you take on full responsibility for the business and its debts.
If you value independence, want to start quickly and have a fairly low-risk business, this structure is often a great fit. It is especially popular for freelancers, tradespeople and small service businesses.
If you expect rapid growth, need outside investment, or want to protect your personal assets, a limited company may serve you better. Weigh the pros and cons against your own goals and risk tolerance before you commit.
Changing from Sole Trader to Limited Company
You are not locked into being a sole trader forever. Many people start this way and switch to a limited company once the business grows or their tax position changes.
To make the change, you register a company at Companies House and tell HMRC about your new structure. The most common reasons to switch are improved tax efficiency at higher profits and the protection of limited liability.

Frequently Asked Questions
What is the difference between self-employed and sole trader?
“Self-employed” is a broad term for anyone who works for themselves. A sole trader is one specific type of self-employed person who runs their business alone. So all sole traders are self-employed, but not everyone who is self-employed is a sole trader, since some use partnerships or limited companies.
Do I have to register as a sole trader immediately?
Not the moment you start. Many people run small side projects without registering at first. But once your profits go over £1,000 in a tax year, you must register for Self Assessment, and no later than 5 October in your second tax year.
Do I need to register with Companies House?
No. Sole traders register with HMRC, not Companies House. You only need to register with Companies House if you set up a limited company or a limited liability partnership.
Do sole traders get a company registration number?
No. Company registration numbers are issued by Companies House only when you form a limited company. As a sole trader, you register with HMRC and receive a Unique Taxpayer Reference (UTR) for tax instead.
How much tax will I pay as a sole trader?
It depends on your profit, since you only pay tax on profit, not total income. You pay income tax at the standard rates, plus Class 4 National Insurance. Keeping clear records of your expenses lowers your profit and reduces your tax bill.
What expenses can I claim as a sole trader?
You can claim costs that are wholly for running the business, such as stationery, software, business travel, marketing, professional fees and staff wages. If you work from home, you can claim a fair share of your household running costs. You cannot claim for personal use.
Can a sole trader have employees?
Yes. Being a sole trader means you carry full responsibility, not that you must work alone. If you hire staff, you must register as an employer with HMRC, run a PAYE payroll and arrange employers’ liability insurance.
Can you have another job and be a sole trader?
Yes. You can be employed and run a business on the side. Your employment income is taxed through PAYE, and your self-employed income is reported through Self Assessment if you earn more than £1,000 from it.
Do sole traders need a business bank account?
It is not a legal requirement, but it is highly recommended. A separate account keeps your business and personal finances apart, which makes your bookkeeping and tax return far easier and more accurate.
