Sole trader or limited company: a practical starting point
Compare responsibility, administration and growth plans before choosing a route.
Understand this before choosing
Compare what changes in real life
Start with the six differences below, then open one route for the benefits, downsides and exact setup actions.
| What changes | Sole trader | Limited company | Ordinary partnership |
|---|---|---|---|
| If things go wrong | You are personally responsible for business debts and claims. | Company liabilities are normally separate, but guarantees, wrongdoing and director decisions can create personal exposure. | Partners can be personally responsible for business debts and for commitments made for the partnership. |
| How profit is taxed | Income Tax and National Insurance on taxable business profit. | The company pays Corporation Tax; salary and dividends have separate personal tax rules. | Each partner pays tax on their share of profit; the partnership also has its own return. |
| Taking money out | Business money is yours, but drawings are not a business expense. | Company money is not automatically yours: take it through salary, expenses, dividends or a properly recorded director's loan. | Profit shares and drawings should follow the partnership agreement and records. |
| Recurring paperwork | Self Assessment; MTD digital records and quarterly summaries may apply by income band. | Annual accounts, Company Tax Return, confirmation statement and changes to company information. | Register the partnership and partners for Self Assessment; the nominated partner manages records and the partnership return. |
| Owners and shares | One owner; no shares or separate company to transfer. | Shares record ownership and can support additional owners, succession or investment. | Ownership, profit share, decision rights and exits should be set in a partnership agreement. |
| Public information | No company accounts on Companies House, although tax and business records are still required. | Accounts and key company, director, shareholder and control information can appear on the public register. | No ordinary partnership accounts at Companies House, but tax and business records remain required. |

Sole trader in detail
You and the business are legally the same person.
Often worth considering when: One person testing or running a lower-complexity business who accepts personal responsibility and does not need shares.
Potential benefits
- Usually quicker to begin and has fewer company-law formalities.
- You control decisions and keep the remaining profit after tax.
- No annual company accounts or confirmation statement at Companies House.
Trade-offs and extra work
- Your home, savings and other personal assets can be exposed if the business cannot meet its obligations.
- You cannot issue shares to investors, and bringing in another owner changes the route.
- MTD can mean compatible software, digital records and quarterly summaries as well as the annual tax return.
What you would need to do next
- 1Check whether you must register for Self Assessment as a sole trader.
- 2Open a separate account or bookkeeping system and keep evidence from the first transaction.
- 3Estimate gross qualifying income and confirm whether MTD applies now or in a later stage.
- 4Check licences, insurance, contracts, data protection and sector rules before trading.
Do not miss: Simple does not mean informal. You still need records, tax planning, suitable contracts and any required permissions or insurance.
Which route should I explore first?
Tick anything that sounds true. This is a reasoned starting point, not a tax or legal decision made for you.
Starting suggestion
Keep the decision open for now
There is not enough information for a useful starting suggestion. Compare exposure, ownership, expected profit, clients and future funding before registering.
Tax depends on profit, other income and how money is taken out. An LLP, CIC, co-operative, charity or other route may fit specialist circumstances. Use an accountant or solicitor where risk, ownership or the tax outcome is material. Compare structures on Business.gov.uk.
