Business guide
Sole trader or limited company
the practical differences
It is one of the first questions every new business asks, and the honest answer is that it depends. This guide explains how each structure works day to day so you can have a more useful conversation with an accountant.
Two very different set-ups
As a sole trader, you are the business. There is no legal separation between you and what you do. You keep the profits after tax, and you are personally responsible for any debts.
A limited company is a separate legal person. It is registered with Companies House, it owns its own money, and it has directors who run it and shareholders who own it. In a small business, that is often the same one person.
Partnerships and other structures exist too. GOV.UK has a short guide to choosing a legal structure that covers them all.
The choice is not permanent. You can change structure later, and many businesses do. What matters now is picking the one that fits your current size, risk and appetite for paperwork.
At a glance
| Point | Sole trader | Limited company |
|---|---|---|
| Setting up | Register with HMRC for Self Assessment | Register with Companies House, with identity checks for directors |
| Liability | Personally responsible for business debts | Usually limited to what you put in, with exceptions |
| Tax | Income tax and National Insurance on profits | Corporation Tax on company profits, then tax on what you take out |
| Paperwork | Records and a yearly tax return | Company accounts, confirmation statement and company tax return |
| Public information | Little is published | Some details appear on the public register |
| Changing later | Can incorporate later | Closing a company takes formal steps |
Being a sole trader
Most small businesses in Blackpool start this way because it is quick and cheap. You can trade under your own name or a business name, as long as it follows the naming rules on GOV.UK.
GOV.UK explains that you need to register for Self Assessment if your trading income goes over the trading allowance, and the deadline to register is 5 October after the end of the tax year you started. The trading allowance has been £1,000 a year for some time, but check GOV.UK for the tax year you are in.
- Simple records and one tax return a year.
- Profits are yours to use without formal paperwork.
- Easy to stop if the business does not work out.
The main downside is personal liability. If the business owes money, creditors can pursue you personally. Insurance helps with some risks, but not all.
Running a limited company
A limited company can make sense when profits grow, when you take on bigger contracts, or when customers expect to deal with a company. It also separates business and personal finances more cleanly.
It comes with formal duties. Directors have legal responsibilities. The company must file accounts and a confirmation statement with Companies House and deal with Corporation Tax with HMRC. Since 18 November 2025, identity verification has been a legal requirement for directors, and new companies need a verified personal code for each director when they register.
A company also needs a registered office address. If you rent a unit, ask your landlord before using the unit as your registered office. At The Rock Factory, ask us on WhatsApp and we will talk it through.
The company's bank account, contracts and invoices should all be in the company's name, not yours. Mixing personal and company money causes problems with tax and can weaken the protection that limited liability gives.
Thinking about tax
People often choose a limited company because they have heard it saves tax. Sometimes it does, sometimes it does not, and the answer depends on your profits, how you take money out, your other income and the rates for the year. That is a calculation for an accountant, not a rule of thumb.
VAT works the same way for both structures. You must register once your taxable turnover goes over the VAT threshold. For 2026/27, GOV.UK guidance puts the threshold at £90,000 of taxable turnover over a rolling 12 months, unchanged since April 2024. Check the current figure before relying on it.
Keep your own records clear whatever you choose. Good records make any accountant's advice cheaper, faster and more reliable.
A simple way to decide
- Start with the riskIf your work could lead to large claims or debts, limited liability carries more weight.
- Look at your likely profitSmall or uncertain profits often favour the simplicity of being a sole trader.
- Consider your customersSome trade customers or contracts prefer working with a company.
- Weigh up the adminBe honest about how much paperwork you will keep on top of.
- Ask an accountantTake your rough figures and get a view based on the current tax year.
Many people start as a sole trader and incorporate later once things are established. Either way, our guide to starting a business in Blackpool covers the next steps.
If you are still unsure, a short paid session with an accountant is usually money well spent. Bring a rough forecast of your first year's sales and costs, and a list of the questions in this guide.
Common myths
- "You need a company to look professional." Customers care more about good work, clear prices and reviews than about letters after your name.
- "Sole traders cannot use a business name." They can, within the naming rules on GOV.UK.
- "A company always pays less tax." It depends on profit levels and how you take money out. Get advice with real numbers.
- "Limited liability protects you from everything." Personal guarantees on loans or leases, and some director duties, can still reach you personally.
- "Setting up a company is a big job." Registering is fairly quick online. It is the ongoing filings that take the effort.
Whichever route you choose, keep business money separate, keep good records and diarise your deadlines. Those habits matter more than the structure itself.
Before you act on this

Questions
Can I switch from sole trader to limited company later?
Yes. Many businesses start as sole traders and incorporate later. There are tax and admin steps involved, so it is worth planning the timing with an accountant.
Do I need an accountant to be a sole trader?
Not legally. Many sole traders do their own Self Assessment. An accountant can still save time and help you claim the right expenses.
Does a limited company protect my house?
Limited liability generally means the company's debts are the company's, but there are exceptions, such as personal guarantees or wrongful trading. Take advice if this is a concern.
Can I use my unit address as my registered office?
Ask your landlord first. At The Rock Factory, tenants can receive mail at their unit, but talk to us on WhatsApp before naming it as a registered office.
Do sole traders and companies have different VAT rules?
The VAT registration threshold applies to both. Once your taxable turnover passes it, you must register, whatever your structure.
Do I have to register a business name?
Sole traders do not register a name with Companies House, but GOV.UK sets out naming rules, such as not using sensitive words without permission. Limited company names are registered at Companies House when the company is formed.
