Choosing the right business structure is a key decision for UK small business owners. Should you operate as a sole trader or set up a limited company? Each option has unique benefits and challenges. This guide explains the differences, helping you decide what suits your business goals. We cover taxes, liability, setup, and more, using clear language and practical advice.
What is a Sole Trader?
A sole trader is a self-employed person who owns and runs their business alone. You and your business are the same legal entity. This means you keep all profits after tax but are personally responsible for debts.
Benefits of Being a Sole Trader
- Simple Setup: Register with HMRC online. It’s free and takes minutes.
- Less Paperwork: File one Self Assessment tax return yearly. No need to register with Companies House.
- Full Control: You make all decisions without consulting others.
- Private Finances: Your business records stay private, unlike limited companies.
- Low Costs: No incorporation fees or mandatory accountant costs.
Drawbacks of Being a Sole Trader
- Unlimited Liability: Personal assets, like your home, are at risk if the business fails.
- Higher Taxes at High Profits: Income tax rates (20-45%) apply above £12,570 (2025/26 tax year).
- Less Credibility: Some clients prefer limited companies for perceived professionalism.
- Limited Funding: Harder to raise capital without shares to sell.
What is a Limited Company?
A limited company is a separate legal entity from its owners. It can have one or more shareholders and directors. The company owns assets and debts, protecting your personal finances.
Benefits of a Limited Company
- Limited Liability: Your personal assets are safe if the business fails. You’re only liable for what you invest.
- Tax Efficiency: Pay 19% corporation tax (2025/26) on profits. Dividends have lower tax rates than income tax.
- Professional Image: Clients and suppliers often view limited companies as more established.
- Funding Options: Sell shares to raise capital or attract investors.
- Tax Reliefs: Claim deductions for training, R&D, and business expenses.
Drawbacks of a Limited Company
- Complex Setup: Register with Companies House for £12 (2025 fees).
- More Paperwork: File annual accounts, corporation tax returns, and a confirmation statement.
- Higher Costs: Expect accountant fees due to complex reporting.
- Public Records: Financial details are public on Companies House.
Key Differences Between Sole Trader and Limited Company
| Aspect | Sole Trader | Limited Company |
|---|---|---|
| Legal Status | Same as the owner | Separate entity |
| Liability | Unlimited, personal assets at risk | Limited, personal assets protected |
| Taxation | Income tax (20-45%) | Corporation tax (19%) + dividends |
| Setup Cost | Free | £12 registration fee |
| Paperwork | Self Assessment only | Annual accounts, tax returns |
| Privacy | Private records | Public records |
Which is More Tax-Efficient?
Tax efficiency depends on your profits. For low profits, sole traders often pay less tax. For higher profits, limited companies can save money.
- Sole Trader: Pay income tax on all profits above £12,570 (2025/26). Rates are 20% (£12,571-£50,270), 40% (£50,271-£125,140), and 45% (above £125,140). You also pay Class 2 (£3.45/week) and Class 4 National Insurance (6% on profits £12,571-£50,270, 2% above).
- Limited Company: Pay 19% corporation tax on profits. Directors take a small salary (e.g., £8,840 tax-free in 2025/26) and dividends (taxed at 8.75% for basic rate, 33.75% for higher rate). This can save £1,000-£2,000 yearly for profits around £50,000.
Example: For £50,000 profit in 2025/26:
- Sole trader: Take-home pay ~£38,620 after taxes and National Insurance.
- Limited company: Take-home pay ~£40,067 with optimal salary-dividend split.
For profits above £100,000, sole traders may face higher taxes due to the 40-45% income tax bands. Limited companies remain advantageous until profits reach £300,000, where tax savings narrow.
When Should You Choose a Sole Trader Structure?
A sole trader structure suits small, low-risk businesses or freelancers starting out.
- Best For:
- Freelancers or side hustles with profits below £20,000.
- Businesses with minimal setup costs and simple operations.
- Owners who value control and privacy.
- Example: A graphic designer earning £15,000 yearly saves ~£150 as a sole trader compared to a limited company.
When Should You Choose a Limited Company?
A limited company is ideal for growing businesses or those with higher risks.
- Best For:
- Businesses with profits above £20,000, where tax savings outweigh admin costs.
- Companies planning to hire employees or seek investment.
- Owners who want to protect personal assets.
- Example: A consultancy firm earning £50,000 yearly benefits from lower taxes and a professional image as a limited company.
How to Decide: Questions to Ask Yourself
To choose the right structure, consider your business needs and goals. Ask these questions:
- What are my profits? Low profits (£15,000-£20,000) favor sole traders. Higher profits benefit from limited company tax savings.
- How much risk is involved? High-risk businesses (e.g., construction) need limited liability to protect personal assets.
- Do I plan to grow? Limited companies support expansion with funding and hiring options.
- Can I handle admin? Sole traders face less paperwork. Limited companies require more record-keeping.
- What do my clients expect? Some industries prefer limited companies for credibility.
People Also Ask: Common Questions Answered
Can I Switch from Sole Trader to Limited Company?
Yes, you can switch by incorporating a limited company with Companies House. Transfer assets, contracts, and clients to the new entity. Notify HMRC to deregister as a sole trader. Consult an accountant to manage taxes and compliance.
Do I Need an Accountant?
Sole traders can often manage taxes themselves if profits are low. Limited companies usually need accountants due to complex filings. Costs for sole traders are lower (£100-£300/year) than for limited companies (£500-£1,500/year).
What About VAT?
Register for VAT if your turnover exceeds £90,000 (2025/26 threshold). Sole traders below this can avoid VAT, offering competitive pricing. Limited companies may also need VAT registration, adding admin.
How Does IR35 Affect Me?
IR35 rules apply to freelancers/contractors. As a sole trader, you’re taxed as self-employed unless deemed an employee by HMRC. Limited companies face stricter IR35 checks, requiring PAYE compliance if “inside” IR35. Seek tax advice.
Practical Steps to Get Started
- Assess Your Business: Estimate profits, risks, and growth plans.

- Sole Trader: Sign up with HMRC online by October 5 after starting.
