Sole Trader vs Limited Company: When Should a Tradesman Go Limited?

The Question Every Growing Tradesman Asks

Earning decent money as a sole trader? You've probably wondered if going limited would save you tax. Maybe your accountant's mentioned it, or you've heard other tradesmen talking about it. Let's break down when it actually makes sense.

The Basic Difference

Sole Trader:

• You and the business are legally the same
• Profits are your income, taxed as income tax + NI
• Simple to set up and run
• Personal liability for business debts

Limited Company:

• Separate legal entity from you
• Company pays corporation tax on profits
• You pay yourself salary and/or dividends
• Limited liability (usually)
• More admin and accounting requirements

The Tax Comparison (Real Numbers)

This is what everyone wants to know. Let's compare at different profit levels:

£30,000 profit:

• Sole trader tax + NI: Approximately £5,000-5,500
• Limited company (salary + dividends): Approximately £4,500-5,000
• Difference: Marginal, maybe not worth the hassle

£50,000 profit:

• Sole trader tax + NI: Approximately £11,000-12,000
• Limited company: Approximately £8,500-9,500
• Difference: £2,000-3,000 savings potentially worth it

£80,000 profit:

• Sole trader tax + NI: Approximately £23,000-25,000
• Limited company: Approximately £17,000-19,000
• Difference: £5,000-7,000 - definitely worth considering

Note: These are rough figures. Tax rules change and individual circumstances vary. Get proper accountant advice for your situation.

Hidden Costs of Going Limited

The tax savings look good, but factor in:

• Accountant fees: £800-2,000/year (vs £300-500 for sole trader)
• Companies House filing: £13-30/year
• Payroll admin: Monthly RTI submissions
• Your time: More paperwork, more decisions
• Business banking: May have monthly fees

At £50,000 profit, if your accountant costs £1,500 more and you value your admin time, the net savings might be £1,000-1,500. Still worth it for some, not for others.

Beyond Tax: Other Reasons to Go Limited

Professional image:

• Ltd after your name can help win bigger contracts
• Some commercial clients prefer dealing with limited companies
• Main contractors may require it

Limited liability:

• If the business owes money, creditors can't (usually) take your house
• Some protection if something goes wrong on a job
• Note: Personal guarantees may be required for loans/leases anyway

Flexibility:

• Easier to bring on a business partner
• Can retain profits in the company
• More options for pension contributions

Reasons to Stay Sole Trader

Simplicity:

• Minimal paperwork
• One tax return per year
• Cash in your pocket is yours

Lower costs:

• Cheaper accountant (or DIY possible)
• No company filing requirements

Privacy:

• Limited companies have public accounts
• Your address is on public record (or you pay for registered office)

Mortgage simplicity:

• Some lenders prefer sole traders
• Director salary/dividends split confuses mortgage applications

The Real Decision Framework

Stay sole trader if:

• Profits under £40,000
• You value simplicity over maximum tax efficiency
• You're planning to get a mortgage soon
• You don't want public records of your finances

Consider going limited if:

• Profits consistently over £50,000
• You're taking on bigger contracts
• Clients require limited company status
• You can handle (or pay for) the extra admin
• You want to retain money in the business

Making the Switch

If you decide to go limited:

1. Talk to an accountant first (seriously, don't DIY this)
2. Choose your year-end date strategically
3. Register with Companies House
4. Open business bank account
5. Register for corporation tax and PAYE
6. Transfer existing business assets/contracts

You can transfer tools and equipment (power tools, hand tools, vehicle) into the company. This has tax implications - get advice on the best approach.

The Bottom Line

Going limited isn't automatically better. It's a trade-off between tax savings and complexity. The breakeven point is usually somewhere around £40,000-50,000 profit, but your personal circumstances matter hugely.

Don't switch just because "everyone's doing it." Run the numbers for YOUR situation with a qualified accountant. The consultation fee is worth it for a decision this significant.
