Sole Trader vs Limited Company: Which Is Right for You in 2026?
As a sole trader you pay income tax on profits (up to 45%) and Class 4 National Insurance (9%). As a limited company director, you pay yourself a low salary plus dividends and pay Corporation Tax on profits (19–25%). The limited company usually wins on tax once your profit exceeds around £30,000–£35,000. But it comes with more admin.

What is a sole trader?#
A sole trader is the simplest business structure in the UK. You register with HMRC for Self Assessment, file an annual tax return, and pay income tax on your profits. There is no legal separation between you and your business — your personal assets (including your home) can be at risk if the business has debts or is sued. The upside is minimal paperwork: no annual accounts, no Companies House filings, and straightforward accounting. Most freelancers, tradespeople, and early-stage businesses start as sole traders.
What is a limited company?#
A limited company is a separate legal entity registered at Companies House. Your liability as a director and shareholder is limited to what you invest — your personal assets are protected in most circumstances. You pay yourself through a combination of salary and dividends. The company pays Corporation Tax on its profits. There is more admin: annual accounts, a Confirmation Statement, a Corporation Tax return, and PAYE if you take a salary. Most business owners with consistent income above £30,000–35,000 find the tax savings justify the extra admin.
The tax comparison: real numbers#
On a £50,000 profit: as a sole trader, you pay approximately £12,200 in income tax and National Insurance combined — leaving you with £37,800. As a limited company director taking £12,570 salary and the rest as dividends, you pay approximately £7,500 in total tax and National Insurance — leaving you with £42,500. That is a saving of around £4,700 per year. At £80,000 profit the saving grows to approximately £9,000 per year. At lower profit levels (under £30,000) the difference is smaller and may not justify the extra cost of accountancy.

Liability and personal protection#
As a sole trader, you are personally liable for all business debts. If a client sues you or you cannot pay suppliers, your personal assets are at risk. As a limited company director, the company is the legal entity — debts belong to the company, not to you personally. Note that personal guarantees on business loans remove this protection for that specific debt. If your work carries risk of claims (design, consulting, contracting), the liability protection of a limited company is valuable independent of the tax argument.
Admin burden: honest comparison#
Sole trader admin is light: one Self Assessment tax return per year, keep records of income and expenses, and register for VAT if you cross the threshold. Quarterly tax payments through Payment on Account if your bill is over £1,000. Limited company admin is heavier: annual accounts (must be filed with Companies House), Corporation Tax return, Confirmation Statement, PAYE reporting if you take a salary, and dividend paperwork. Most limited company directors pay an accountant £800–£1,800 per year to handle this. Add this cost to your calculations when comparing net income.
When you should switch from sole trader to limited company#
The three clearest triggers to switch are: your profit consistently exceeds £35,000 (the tax saving exceeds the accountancy cost); you are winning contracts where clients prefer to work with limited companies (common in IT contracting and corporate consulting); or you want liability protection because your work carries meaningful legal or financial risk. Switching mid-year is possible but creates a messy accounting period — most people switch at the start of a new tax year. When you incorporate, your sole trader business closes and you start fresh as a limited company.
People also ask
Which is better — sole trader or limited company?
For income below £30,000 per year, sole trader is usually simpler and the tax difference is minimal. Above £35,000 profit, a limited company typically saves £3,000–£9,000+ in tax annually. Limited companies also offer personal liability protection that sole traders do not.
Can I switch from sole trader to limited company?
Yes. You register a new limited company with Companies House and cease trading as a sole trader. If you are transferring assets (like a trade name or customer contracts) from the sole trader business to the company, get advice from an accountant on how to do this tax-efficiently.
Do sole traders pay less tax than limited companies?
Sole traders usually pay more tax overall once profits exceed £30,000–£35,000. A sole trader pays income tax (up to 45%) and Class 4 NI (9%) on all profits. A limited company director pays Corporation Tax (19–25%) on company profits, then lower-rate dividend tax on money drawn — making the combined rate significantly lower.
Can a sole trader have employees?
Yes. A sole trader can employ people. You set up PAYE with HMRC and deduct income tax and National Insurance from employees' wages. Your legal obligations as an employer are identical whether you are a sole trader or limited company.
