How the Comparison Works
What the estimator is doing behind the scenes
Sole Trader Route
Your full profit is taxed as personal income, using Income Tax bands plus Class 4 and Class 2 National Insurance, regardless of how much you draw out of the business.
Limited Company Route
The company pays Corporation Tax on its profits after deducting a director’s salary, then whatever is left can be paid out as dividends.
Salary + Dividends
Your salary uses your tax-free Personal Allowance, and dividends are taxed separately at lower dividend tax rates, with a small tax-free dividend allowance.

Key Differences at a Glance
The core distinctions that usually decide which structure is right for a UK business owner.
| Factor | Sole Trader | Limited Company |
|---|---|---|
| Legal Status | You and the business are the same legal entity. | A separate legal entity from its director(s) and shareholder(s). |
| Liability | Unlimited — personal assets are at risk if the business owes money. | Limited to what you’ve invested in shares, in almost all cases. |
| Tax on Profit | Income Tax (20% / 40% / 45%) plus Class 4 & Class 2 National Insurance on all profit. | Corporation Tax (19%–25%) on company profit, then dividend tax only on what you withdraw. |
| Admin & Filing | Register for Self Assessment; file one tax return a year. | File statutory accounts, a Corporation Tax return, a confirmation statement and payroll if salaried. |
| Public Disclosure | Financial details stay private. | Accounts and director details are public via Companies House. |
| Setup Cost & Speed | Free, register with HMRC any time before 5 October after your first tax year. | Small Companies House fee; can be incorporated online within 24 hours. |
| Perception | Can appear less established to larger clients or lenders. | Often seen as more credible for contracts, tenders and finance applications. |
| Profit Extraction | All profit is yours as soon as it’s earned. | Profit belongs to the company until paid out as salary or dividends. |

Sole Trader vs Ltd FAQ
Answers to the most frequently asked questions about choosing between a Sole Trader and a Limited Company in the UK.
It depends on your profit level and priorities. Sole trader status is simpler and cheaper to run, which suits lower profits or businesses just starting out. A limited company is usually more tax-efficient once profits rise above roughly £30,000 to £40,000 a year, because profits can be extracted as dividends taxed at lower rates than income tax, but it comes with more admin, filing duties and public disclosure.
Often, yes, at higher profit levels. A limited company pays Corporation Tax on profits, then the owner pays dividend tax only on what they draw out, and dividends are not subject to National Insurance. A sole trader pays Income Tax and Class 4 National Insurance on the full profit, regardless of how much is withdrawn from the business, which can mean a higher combined tax rate as profits grow.
As a sole trader there is no legal separation between you and the business, so you have unlimited personal liability. If the business cannot pay its debts, runs into a legal dispute, or is sued, your personal assets such as savings, your car, or even your home can be used to settle what is owed.
Registering a limited company with Companies House costs a small statutory fee and can be done online within 24 hours. The larger ongoing cost is typically accountancy support, since limited companies must file statutory accounts, a Corporation Tax return and a confirmation statement every year, which most owners pay an accountant to handle.
Yes, this is common and is usually called incorporation. You register a new limited company, transfer the trade, assets and any contracts across, and deregister as self-employed once the switch is complete. Many businesses start as sole traders to test an idea cheaply, then incorporate once profits justify the extra admin.
