Choosing between operating as a sole trader and forming a limited company affects how you pay tax, take money from the business, protect personal assets and handle paperwork. There is no universal winner: the right structure depends on your profit, risk, plans and personal circumstances.
This guide compares sole trader vs limited company status for the 2026/27 tax year and explains the questions to discuss with an accountant before deciding.
Sole trader vs limited company at a glance
| Area | Sole trader | Limited company |
|---|---|---|
| Legal status | You and the business are legally the same | The company is a separate legal person |
| Tax | Income Tax and Class 4 National Insurance on taxable profits | Corporation Tax on company profits, plus personal tax when money is extracted |
| Liability | Generally unlimited personal liability | Usually limited, subject to important exceptions |
| Administration | Usually simpler | More filing, payroll and company-law duties |
| Privacy | Less financial information is public | Company details and filed accounts are publicly available |
| Money | Business profit belongs to you | Company money belongs to the company |
What is a sole trader?
A sole trader runs a business as an individual. You keep the profits after tax, but you are personally responsible for business debts. You normally register for Self Assessment, keep business records and report taxable profit to HMRC.
This structure is popular with freelancers, tradespeople, consultants and small owner-operated businesses because setup and ongoing administration are relatively straightforward. You can still employ people, register for VAT and use a trading name.
What is a limited company?
A private limited company is legally separate from its owners. It has shareholders and at least one director. A one-person business can have the same individual as sole director and sole shareholder.
The company owns its cash, equipment and contracts. Directors must act in the company’s interests, keep adequate records, file annual accounts and a confirmation statement, and ensure the company meets its tax obligations. Hiring an accountant helps, but directors remain legally responsible.
How does personal liability differ?
A sole trader is normally personally responsible for business debts and legal obligations. If the business cannot pay, personal assets may be exposed. Appropriate insurance and sound contracts remain important.
A limited company’s shareholders usually have limited liability. However, protection is not absolute. A lender or landlord may request a personal guarantee, while misconduct, wrongful trading or mixing personal and company money can create serious problems.
Businesses with employees, valuable contracts, borrowing, stock or higher professional risk may give liability greater weight than a low-risk freelancer would.
How sole traders pay tax in 2026/27
A sole trader pays Income Tax on taxable business profit after allowable expenses. Tax is based on profit, not the amount withdrawn from the bank account. Other income also affects the calculation.
For 2026/27, self-employed people generally pay Class 4 National Insurance at 6% on profits over £12,570 up to £50,270, and 2% above £50,270. Class 2 is normally treated as paid when profits reach the relevant threshold, protecting the National Insurance record without a compulsory weekly payment.
Payments on account can create a cash-flow surprise. They usually require advance payments towards the next Self Assessment bill, so sensible tax reserves matter.
How limited companies pay tax
A company pays Corporation Tax on taxable profits. The small profits rate is 19% for profits of £50,000 or less, while the main rate is 25% above £250,000. Marginal Relief applies between those limits. Thresholds can be reduced where companies are associated.
Corporation Tax is only the first layer. A director-shareholder may also pay Income Tax and National Insurance on salary, and Income Tax on dividends. For 2026/27, dividend tax rates are 10.75%, 35.75% and 39.35%, depending on the taxpayer’s band, with a £500 dividend allowance.
Therefore, incorporation does not automatically produce a tax saving. Salary, dividends, pension contributions, retained profit, other household income and future plans all affect the result.
Taking money from the business
A sole trader can move money between business and personal accounts as drawings. Those transfers do not determine the tax bill; taxable profit does.
A director cannot simply treat the company’s bank balance as personal money. Funds generally leave through salary, dividends, reimbursed expenses, pension contributions or a properly recorded director’s loan. Dividends need sufficient distributable profit and the required paperwork. An overdrawn director’s loan can lead to additional tax consequences.
Expenses and pension contributions
Both structures can deduct qualifying business costs, although detailed rules and treatment can differ. Costs must be supported by good records and have a genuine business purpose.
Company pension contributions can be attractive where they meet the relevant rules, while sole traders normally receive personal tax relief on qualifying pension contributions. Advice is valuable because contribution limits, available profits and personal circumstances interact.
Administration and accounting costs
Sole trader accounts are usually simpler. You need accurate income and expense records, a Self Assessment return and any relevant VAT or payroll submissions. Making Tax Digital for Income Tax is also being phased in based on qualifying income.
A limited company normally needs statutory annual accounts, a Company Tax Return, Corporation Tax calculations and a confirmation statement. Payroll is often required for director salary, and dividend paperwork must be retained. Companies House identity-verification and filing requirements also need attention.
These obligations normally make limited-company accountancy more expensive. The extra cost should be considered alongside any tax, commercial or risk benefits.
Privacy and professional image
A sole trader’s tax return is private. A limited company’s registered office, directors, people with significant control and filed accounts are generally searchable at Companies House.
Some customers, agencies and lenders prefer dealing with limited companies. A company can also make it easier to add shareholders or build an asset that may later be sold. However, many successful businesses operate as sole traders, so incorporation is not proof of quality.
VAT and employing staff
The choice of structure does not avoid VAT. A sole trader or company generally must register when taxable turnover exceeds the current registration threshold, and either can register voluntarily.
Both can employ staff. Each must operate PAYE, meet pension auto-enrolment duties when applicable, keep payroll records and comply with employment law. A limited company director who takes salary is usually processed through the company’s payroll.
What happens to losses?
Sole trader losses may, subject to conditions, be set against other income or carried to other periods. This can be valuable in an early loss-making year.
Company losses belong to the company. They may be carried or relieved under Corporation Tax rules, but they do not normally reduce the director’s unrelated personal income. Loss relief is technical, so obtain advice before relying on it.
When a sole trader structure may suit you
- You are testing a new or low-risk business idea.
- You want simple administration and lower compliance costs.
- You expect modest profits or early losses.
- You need most business profit for personal living costs.
- You do not need shareholders or outside investment.
When a limited company may suit you
- You want a separate legal entity and limited liability.
- You plan to retain some profit for growth rather than withdraw everything.
- You want to bring in shareholders or eventually sell the company.
- Clients or tender processes prefer an incorporated supplier.
- Your profit level and extraction plans make the overall tax position competitive after extra costs.
Is there a profit level where you should incorporate?
Be cautious with rules of thumb. Two owners earning the same profit can receive different answers because of other income, student loans, child benefit, pension goals, number of shareholders and how much cash they need to withdraw.
A useful comparison models at least one full year under both structures. Include Corporation Tax, salary taxes, dividend tax, National Insurance, accountancy fees and retained profit. Then assess non-tax matters such as liability and commercial plans.
Can you change from sole trader to limited company?
Yes. Many businesses begin as sole traders and incorporate later. The change requires more than opening a company: contracts, assets, stock, registrations, insurance, invoicing, payroll and bank arrangements may need transferring.
Tax relief may be available when a business is transferred, but timing and documentation matter. Check the position before moving assets or issuing the first company invoice.
A practical decision checklist
- Forecast profit and how much cash you need personally.
- List your commercial and legal risks.
- Consider customers, finance and future owners.
- Compare total tax and compliance costs.
- Review privacy and administrative obligations.
- Plan how losses, pensions and retained profits will be handled.
- Revisit the decision as the business grows.

Frequently asked questions
Can a sole trader become a limited company later?
Yes. You can incorporate when the benefits justify the extra work. Plan the transfer carefully so assets, registrations and contracts are dealt with correctly.
Does a limited company always pay less tax?
No. The combined company and personal tax position depends on profit, salary, dividends, other income and how much money is withdrawn.
Can I have employees as a sole trader?
Yes. Sole traders can employ staff, but must meet the payroll, pension and employment responsibilities that apply to employers.
Which structure is easier to close?
A sole trade is usually simpler to cease. Closing a solvent limited company involves formal company and tax steps, and extracting remaining funds can have tax consequences.
