The "Default" Advice Has Changed
For years, the standard advice for UK contractors was "Go Limited to save tax." In the 2026/27 tax landscape, that rule is broken. With the Corporation Tax rate hike and the Dividend Allowance slashed to just £500, the administrative cost of a Limited Company often outweighs the tax savings for low-to-mid earners.
If your profit is below £50,000, remaining a Sole Trader is frequently the mathematically superior choice. This guide breaks down the math, the liability, and the admin so you can decide.
At a Glance: Key Differences
| Feature | Sole Trader | Limited Company |
|---|---|---|
| Personal Liability | 100% Unlimited. You and the business are the same legal entity. If the business fails, you are personally liable for debts. | Limited. The company is a separate legal entity. Your personal assets are generally protected from business debts. |
| Tax Efficiency (£50k) | High. You pay Income Tax and National Insurance only on profit. Simple and effective. | Lower. You pay Corporation Tax (19-25%) on profits, then Dividend Tax on withdrawals. |
| Privacy | Private. Your accounts are not published publicly. | Public. Your name and registered address are published on Companies House. |
| Administration | Low (£0 - £300/yr). Self Assessment once a year. DIY is easy. | High (£1,200+/yr). Requires Annual Accounts, Confirmation Statements, and usually an accountant. |
Living in Scotland? The Math is Different.
Scotland has distinct Income Tax bands. As a Sole Trader, you pay these Scottish rates, which are generally higher than the rest of the UK for earnings over ~£28,000. However, Dividend Tax is set by the UK Government and applies equally across the whole UK.
The Implication: Because Scottish Sole Traders face higher Income Tax rates (e.g., 42% vs 40%), the tax savings of switching to a Limited Company are often greater for Scottish residents.
The Tipping Point: A Scottish freelancer might find incorporating viable slightly earlier than £50,000 to avoid the 42% Higher Rate band that kicks in at £43,663.
Warning: The £500 Dividend Allowance Trap
Be aware that the tax-free Dividend Allowance is only £500 for the 2026/27 tax year, and dividend tax rates rose by 2pp from April 2026. This "fiscal drag" significantly reduces the benefit of paying yourself via dividends. Before incorporating, calculate if the tax saving covers your accountant's annual fee.
Which structure fits your income?
I earn under £50,000 / year.
Simplicity wins here. The tax difference is negligible, and the admin savings of being a Sole Trader are substantial.
I earn over £80,000 / year.
The Limited Company structure allows you to retain profits within the company (paying only 19-25% Corp Tax) rather than withdrawing them at higher Income Tax rates.
