The Two Most Common Business Structures
When starting a business in Glasgow, one of the first decisions you need to make is your legal structure. The two most common options are operating as a sole trader or forming a limited company. Each has distinct advantages, tax implications and compliance requirements. The right choice depends on your income level, liability risk and long-term plans.
What is a Sole Trader?
A sole trader is a self-employed individual who runs their business as themselves. There is no legal separation between you and your business — you are personally responsible for all debts and liabilities. Registration is simple: you just register with HMRC for Self-Assessment.
✓ Advantages
- Simple to set up — just register with HMRC
- Low compliance costs and paperwork
- Full control over your business
- No Companies House filing required
- Business losses offset against other income
✗ Disadvantages
- Unlimited personal liability for business debts
- Less tax-efficient at higher profit levels
- Can appear less credible to some clients
- Harder to raise investment
- No separation between personal and business assets
What is a Limited Company?
A limited company is a separate legal entity from its owners (shareholders). Your personal assets are protected from business debts. It must be registered with Companies House and has more complex compliance requirements including annual accounts and Corporation Tax returns.
✓ Advantages
- Limited liability — personal assets protected
- More tax-efficient at higher profit levels
- More credible to clients and suppliers
- Profits can be retained in the company
- Easier to bring in investors or shareholders
✗ Disadvantages
- More complex setup and administration
- Annual accounts filed publicly at Companies House
- Higher accountancy costs
- Less flexibility in accessing profits
- Director duties and legal obligations
Tax Comparison: Sole Trader vs Limited Company
Tax is the biggest factor in this decision. Here is how the two structures compare at different profit levels for 2024/25:
| Annual Profit | Sole Trader Tax | Limited Company Tax | Saving (approx) |
|---|---|---|---|
| £20,000 | ~£1,840 | ~£2,400 | Sole trader cheaper |
| £35,000 | ~£6,500 | ~£5,800 | ~£700 saving |
| £50,000 | ~£12,500 | ~£9,200 | ~£3,300 saving |
| £80,000 | ~£25,000 | ~£17,500 | ~£7,500 saving |

When Should You Switch from Sole Trader to Limited Company?
Most accountants advise considering incorporation when your annual profit consistently exceeds £35,000 to £40,000. At this level the Corporation Tax saving typically outweighs the additional accounting costs. Other reasons to incorporate include:
- You want to protect your personal assets from business risk
- Your clients require you to operate through a limited company
- You want to bring in business partners or investors
- You plan to sell the business in future
- You want to retain profits in the business rather than draw them all out
