One of the first decisions a new business makes is how to be set up. Sole trader and limited company are the two common answers, and neither is automatically the right one. It comes down to how you work, how much risk you carry and how you want to pay yourself.
What a sole trader is
As a sole trader you and the business are the same legal person. You keep the profits after tax, you are responsible for the debts, and there is less administration to keep up with. You report your income through a Self Assessment return, and if you are just starting you register with HMRC by 5 October after the tax year in which you began.
For many freelancers and trades, this is the simplest place to start. It is quick to set up, cheap to run and easy to understand.
What a limited company is
A limited company is a separate legal entity. It has its own name, its own bank account and its own responsibilities. You become a director, and usually a shareholder, which brings duties as well as benefits. The company files accounts and a confirmation statement at Companies House, and deals with Corporation Tax on its profits.
The main draw is that the company is separate from you. That separation can limit your personal liability for business debts, and it can change how you take money out, through a mix of salary and dividends. It also means more paperwork, and more care about the rules on loans and expenses.
How to decide
There is no single test, but a few questions point the way.
- How much financial risk does the work carry, and could a customer claim against you?
- Do clients or contracts expect to deal with a limited company?
- How do you want to be paid, and how much profit do you expect to leave in the business?
- How much admin are you willing to keep on top of each month?
- What are your plans over the next few years?
Answer those honestly and the shape often becomes clear. If the two options still feel close, the deciding factor is usually the risk, not the tax.
Getting the setup right
Whichever you choose, the early housekeeping is the same. Open a separate bank account, keep business and personal spending apart, and set a simple routine for saving receipts. If you are a sole trader, remember that Making Tax Digital for Income Tax applies from 6 April 2026 to sole traders and landlords with qualifying income over £50,000, and to those over £30,000 from April 2027, so digital records will matter soon for many people.
The right answer can also change. A business that is a sole trader today may suit a limited company in two years, and changing then is normal rather than a failure. The important thing is to decide in time, set up cleanly and keep good records from day one.
