Sole trader or limited company
Which is right for you?
This is one of the questions we get asked most, usually from someone who started out freelancing or running a small side business and is now doing well enough that the question feels urgent. There isn't a single right answer, but there is a right answer for your situation, and it comes down to understanding what changes between the two.
Sole trader, in plain terms
As a sole trader, you and your business are the same legal entity. You register for Self-Assessment, keep records of your income and expenses, and pay Income Tax and Class 4 National Insurance on your profits, after allowable expenses. The admin is relatively light. There's no separate company to register, no Companies House filings, and no requirement for statutory accounts in the way a limited company has.
The trade-off is personal liability. If the business runs into debt or gets sued, there's no legal separation between the business and you personally. Your own assets are, in principle, on the line.
Limited company, in plain terms
A limited company is a separate legal entity from you. It can own assets, owe debts and be sued in its own right, which means your personal liability is generally limited to what you've invested in the company, hence the name. This protection is one of the main reasons people incorporate.
The company pays Corporation Tax on its profits. Currently that's 19 percent on profits up to £50,000, 25 percent on profits over £250,000, and a tapered rate in between through what's called Marginal Relief. As a director, you then typically pay yourself through a combination of a salary and dividends, rather than simply drawing profit the way a sole trader does. Dividends come with their own tax rules, including a £500 tax-free dividend allowance and dividend tax rates on anything above that.
You'll file a Confirmation Statement and statutory accounts with Companies House each year, plus a Company Tax Return with HMRC, on top of running payroll if you take a salary.
Where the tax difference sits
Historically, running profits through a limited company and drawing them as dividends was often more tax-efficient than taking the same amount as sole trader profit, because dividends aren't subject to National Insurance. That gap has narrowed in recent years as dividend tax rates have risen, so it's worth running the comparison for your own profit level rather than assuming incorporation automatically saves you money. For some businesses it still does, quite comfortably. For others operating at lower profit levels, the extra admin of a limited company may not be worth it purely on tax grounds.
Reasons beyond tax
Tax is rarely the whole story. A limited company can look more established to bigger clients or suppliers, some of whom simply prefer, or require, dealing with a limited company. Limited liability matters more if your work carries financial or legal risk. Some people also find it easier to separate “business money” from “my money” psychologically once there's a company in between, which sounds small but genuinely helps some business owners manage cash flow better.
On the other side, some people value the simplicity of sole trader status while they're building up the business and aren't ready for the extra filing obligations.
Making the switch later
If you start as a sole trader, you're not locked in. Plenty of businesses incorporate once they've grown, once the liability protection starts to matter more, or once the tax numbers tip in favour of it. The transition itself is a process worth planning properly, covering things like transferring assets, closing off your Self-Assessment position, and getting your bookkeeping switched over to the new entity cleanly.
The bottom line
There's no universal right choice, only the right choice for your numbers, your risk, and where your business is heading. It's a decision worth working through properly rather than guessing, because the wrong structure can cost you more in the long run than the accountancy fees ever would.
