Should I register as a sole trader vs limited company?

Aug 18, 2025

When you’re starting your own business, choosing the right structure is a big step. Get it right and you’ll save time, money, and stress. Here’s a plain-English guide to help you choose between becoming a sole trader or setting up a limited company.

Legal Setup

Sole Trader
You and the business are the same. You keep all the profits, but you’re also personally responsible for any debts.

Limited Company
The business is its own legal entity. You’re a director and shareholder. Profits belong to the company first, and you decide how to pay yourself.

Pros & Cons

Sole Trader

Pros

  • Easy and cheap to set up
  • Fewer rules and admin
  • Keep all the profits
  • Full control of decision-making

Cons

  • You’re personally liable for business debts
  • Less tax-efficient once profits grow
  • May be seen as less professional by some clients

Limited Company

Pros

  • Limited liability protects your personal assets
  • Can be more tax-efficient
  • Easier to attract investment and funding
  • Seen as more established and professional

Cons

  • More admin: register with Companies House, file annual accounts
  • Financial info is public
  • Costs more to run (e.g. accountant, fees)

Tax: What You Pay

Sole Trader
You pay Income Tax plus National Insurance on your profits.

Limited Company
The company pays Corporation Tax on its profits. You pay yourself through salary (taxed) and dividends (lower tax rates).

If you’re making under £25–30k profit a year, staying as a sole trader might be more cost-effective. Over that? You might save money with a limited company.

When to Choose What

Ask yourself:

  • Want full control and fewer rules? Sole Trader
  • Need liability protection? Limited Company
  • Planning to grow or raise investment? Limited Company
  • Just starting out or testing an idea? Sole Trader

Can You Switch Later?

Yes. Many people start as a sole trader and move to a limited company when things grow.

To switch:

  • Pick a company name
  • Register with Companies House
  • Let HMRC know
  • Transfer business assets
  • Open a business bank account
  • Tell your clients and suppliers
