Choosing the right business structure is one of the most important decisions you will make. Here is an honest comparison of both options based on current HMRC rules.
1. The Big Picture
Self-Employed (Sole Trader)
- You and the business are legally the same
- You pay Income Tax and National Insurance on profits
- Simpler setup and reporting
- You are personally liable for business debts
Limited Company
- The company is a separate legal entity
- The company pays Corporation Tax
- You pay tax on salary and/or dividends
- More administration, but limited liability
2. Tax Position in 2026
Self-Employed Taxation
As a sole trader, you pay tax on all profits. There is no separation between business income and personal income. Income Tax rates: 20% basic, 40% higher, 45% additional. Plus Class 2 and Class 4 National Insurance.
Limited Company Taxation
A limited company pays Corporation Tax: 19% for small profits, up to 25% for higher profits. You then pay personal tax on money you take out as salary (subject to PAYE and NIC) and dividends (taxed at dividend rates after the annual dividend allowance).
3. Which Is More Tax-Efficient?
- Lower profits: self-employed is often simpler and cheaper
- Higher profits: a limited company can offer better tax planning flexibility
- Reinvesting profits: a limited company is usually more efficient
- Taking all profits personally: the difference narrows
There is no automatic tax saving just from having a limited company. Poor planning can make a company more expensive than sole trading.
4. National Insurance: A Key Difference
Self-employed individuals pay NIC directly on profits. Limited company directors often take a low salary and do not pay Class 4 NIC on dividends. This is one reason companies can be more efficient, but only when structured correctly.
5. Administration and Compliance
Self-Employed
- Annual Self Assessment
- Basic bookkeeping
- Fewer deadlines
- Lower accounting costs
Limited Company
- Annual accounts to Companies House
- Corporation Tax return (CT600)
- Payroll (even for one director)
- Confirmation Statement
- Dividend paperwork
- Stricter HMRC scrutiny
If compliance is done incorrectly, penalties can easily outweigh tax savings.
6. Legal Protection and Risk
Self-employed means unlimited personal liability. A limited company generally limits liability to the company. For higher-risk activities or growing businesses, this alone can justify incorporation.
7. So What Actually Makes Sense in 2026?
Self-Employed May Be Better If:
- You earn a modest or irregular income
- You want simplicity
- You take all profits personally
- You are just starting out
Limited Company May Be Better If:
- Profits are consistently higher
- You plan to reinvest
- You want limited liability
- You value long-term tax planning
- You are prepared for compliance obligations
The Most Common Mistake
The biggest mistake is choosing a structure based on hearsay. The right structure depends on your numbers, not general advice.
