Sole Trader vs Limited Company: The Accounting Differences
The practical accounting, tax and reporting differences between operating as a sole trader and a limited company in the UK.
Published 8 October 2026 · The Newcastle Accountants Team
Choosing between operating as a sole trader and a limited company is one of the first big decisions for a UK business. Both are legitimate; they simply suit different situations. Here are the practical accounting and tax differences.
Legal status and liability
A sole trader and their business are legally the same, you keep the profits but are personally liable for any debts. A limited company is a separate legal entity, which generally limits your personal liability, but brings more formality.
Tax treatment
A sole trader pays Income Tax and National Insurance on business profits through Self Assessment. A limited company pays Corporation Tax on its profits (from 19% to 25% depending on profit level), and directors then pay personal tax on the salary and dividends they draw. Depending on your profit level, a company can be more tax-efficient, but not always.
Accounts and filing
- Sole trader: keep records and file a Self Assessment return each year.
- Limited company: file statutory accounts and a confirmation statement at Companies House, a Corporation Tax return (CT600) with HMRC, and each director files their own Self Assessment. Company accounts are also on the public record.
Privacy and admin
Sole traders keep their finances private and have lighter admin. Companies have more filing obligations, and key details appear on the public Companies House register.
Which is right for you?
It comes down to your profits, plans, attitude to risk and appetite for admin. A company can offer tax efficiency and limited liability; a sole trader set-up offers simplicity and privacy. We model the difference for your specific numbers so you can decide with confidence. See our pages on limited company accounts and accountants for sole traders for more.

Related questions
It can be, particularly at higher profit levels, because of how Corporation Tax, salary and dividends interact. But it brings more admin and public filing, so the right answer depends on your circumstances.
Yes. Many businesses start as sole traders and incorporate once profits and plans justify it. We handle the transition and the registrations.
