Sole Trader vs Limited Company: Which Should You Choose?

A sole trader is simpler to run but leaves you personally liable for the business. A limited company protects your personal assets but comes with more paperwork and reporting. Here's what actually separates the two, so you can pick the right one for where your business is right now.

Key Takeaways

• Sole traders file one annual Self Assessment return. Limited companies file a Confirmation Statement, statutory accounts, and Corporation Tax returns too.
• A limited company is a separate legal entity, so your personal assets are protected if the business runs into financial trouble. A sole trader's aren't.
• Limited companies currently pay 19% Corporation Tax on profits up to £50,000, rising to 25% above £250,000, with marginal relief in between.
• Paying yourself through salary and dividends as a limited company director can be more tax-efficient, though dividend tax rates have risen and the dividend allowance is now just £500 a year.
• Neither structure is permanently "better." Many businesses start as a sole trader and incorporate later as profit and risk grow.

What Is a Sole Trader?

A sole trader runs their business as an individual, and keeps whatever's left after expenses and tax. There's no legal separation between you and the business, which is both the appeal and the risk.

You'll file an annual Self Assessment tax return and pay Income Tax and National Insurance on your profit. If your turnover crosses the VAT registration threshold, currently £90,000, you'll need to register for VAT too, and you can register voluntarily below that if it suits you. Because you and the business aren't legally separate, you're personally responsible for any losses the business makes.

What Are the Benefits of Being a Sole Trader?

The main benefits are simplicity and privacy. There's less to file, less to track, and less of your information sitting on a public register.

• Less paperwork. Limited companies file Corporation Tax returns, annual accounts, and VAT returns on top of Self Assessment. Sole traders just handle Self Assessment.
• Simpler accounts. Fewer filings generally means fewer expenses and less admin to track through the year.
• Privacy. Limited companies have to list director and shareholder details publicly at Companies House. Sole traders don't have to make any of this public.

What Is a Limited Company?

A limited company is a separate legal entity from you personally, even if you're the sole director and shareholder. That separation is what "limited" refers to: your liability is generally limited to what you've paid for your shares, not your personal assets.

As a director, you're responsible for the company's legal and financial decisions, but the company's assets and debts stay separate from your own. You'll need to file a Confirmation Statement and statutory accounts with Companies House every year, plus Corporation Tax returns and any other filings HMRC requires, such as VAT or PAYE if they apply. If you pay yourself a salary or dividends, both need to go on your personal Self Assessment return too.

How Does Limited Company Tax Actually Work?

You can pay yourself through a mix of salary and dividends, and the combination often works out more tax-efficient than taking everything as salary alone. But the gap has narrowed in recent years, so it's worth checking your actual numbers rather than assuming.

Corporation Tax currently sits at 19% on profits up to £50,000 and 25% on profits above £250,000, with marginal relief tapering the rate in between. Dividends are paid out of profit after Corporation Tax, and the dividend allowance, the amount you can take tax-free, is currently just £500 a year, considerably lower than it used to be. Dividend tax rates have also risen: 10.75% for basic rate taxpayers, 35.75% for higher rate, and 39.35% for additional rate. The right mix of salary and dividends depends on your specific profit level, so it's worth running the numbers with an accountant rather than assuming the old rules of thumb still apply.

Rates and thresholds above are correct at the time of writing. Tax rates change, usually at the start of each tax year, so double-check current figures on GOV.UK or with your accountant before making decisions based on them.

What Are the Benefits of a Limited Company?

Beyond the tax planning angle, a limited company structure offers real protection and credibility that a sole trader setup doesn't.

• Limited liability. Your personal assets are protected if the company runs into financial difficulty or has to close.
• Potential tax efficiency. Structuring pay through salary and dividends can reduce your overall Income Tax and National Insurance, depending on your profit level.
• Borrowing power. A limited company can build its own credit history, separate from your personal credit rating.
• Credibility. Some clients prefer working with limited companies, and a few won't work with unincorporated businesses at all.

Which Structure Should You Choose?

There's no universally "better" option. It depends on your current profit level, how much risk you're carrying, and how much admin you're willing to take on.

Many businesses start as a sole trader while testing an idea, then incorporate once profit grows or the liability protection starts to matter more. If you're already thinking about funding or contracts that favour incorporated businesses, our guide to writing a grant application touches on why many grants favour limited companies specifically.

If you're ready to incorporate, our step-by-step guide to forming a limited company walks through the process, and it's worth protecting your business name properly at the same time.

FAQs

Can I switch from a sole trader to a limited company later?

Yes, plenty of businesses do exactly this once profit or risk grows. There's no requirement to pick one structure and stick with it forever.

Do I pay less tax as a limited company?

It depends on your profit level. The gap has narrowed with lower dividend allowances and higher dividend tax rates, so it's worth checking your actual numbers with an accountant rather than assuming.

Is my personal home at risk as a sole trader?

Potentially, yes. Since there's no legal separation between you and the business, personal assets can be at risk if the business can't cover its debts.

Only once your taxable turnover passes the current VAT threshold of £90,000, though you can register voluntarily below that if it works for your business.

What's the current dividend allowance?

£500 a year. Dividends above that are taxed at 10.75% for basic rate taxpayers, 35.75% for higher rate, and 39.35% for additional rate.

Is a limited company more credible to clients than a sole trader?
