Sole Trader vs Limited Company for Tradespeople — Which Is Better in 2026?

Every tradesperson hits this question eventually.

You start out as a sole trader because it is simple. Then the work picks up, the profit climbs, and someone in the merchants or down the pub tells you that you are paying too much tax and you should "go limited".

So which is actually better?

The honest answer is: it depends on your profit, your appetite for paperwork, and how much risk your work carries. Here is the plain-English version, with no accountant waffle.

What a sole trader actually is

Being a sole trader means you and the business are the same legal thing.

You keep all the profit, you file one Self Assessment tax return a year, and you pay income tax and Class 4 National Insurance on your profit.

It is the default. If you have already registered as self-employed, you are a sole trader.

The upside is simplicity. The downside is that there is no legal wall between you and the business. If the business owes money, you owe money.

What a limited company actually is

A limited company is a separate legal entity. It is registered at Companies House, it has its own bank account, and it pays Corporation Tax on its profit.

You become a director and usually the only shareholder. You pay yourself with a mix of a small salary and dividends, and you pay personal tax on what you take out — not on what the company earns.

The big draw is limited liability. If the company runs into trouble, your personal house and savings are generally protected. The trade-off is more admin, more deadlines, and more cost.

The tax difference, roughly

This is the bit everyone wants to know.

As a sole trader, you pay income tax on your profit above the personal allowance, plus Class 4 NI. Profit is profit — there is no separating yourself from the business.

As a limited company, the company pays Corporation Tax (19% on profits up to £50,000, rising towards 25% above that). You then pay yourself a small salary and take the rest as dividends, which are taxed at lower rates than wages.

For a lot of trades, going limited starts to save tax once your profit is comfortably into the higher-rate territory — often somewhere north of £40,000 to £50,000 of annual profit. Below that, the savings are small and may not be worth the extra hassle.

These thresholds and rates change most years, so always check the current HMRC figures or run your numbers past an accountant before deciding. This is general information, not personal tax advice.

The paperwork difference

This is where a lot of tradespeople get caught out.

A sole trader files one tax return a year and keeps records. That is basically it.

A limited company has to:

File annual accounts with Companies House
File a Corporation Tax return with HMRC
File a confirmation statement each year
Run payroll if you take a salary
Keep the company and personal money completely separate
Still do a personal Self Assessment as a director

Most limited company tradespeople pay an accountant to handle this, which typically costs more than sole trader accounts. Factor that cost in when you do the maths.

When limited liability really matters

The tax saving gets all the attention, but liability is often the better reason to go limited.

If you do high-value work, take on subcontractors, sign large contracts, or work where a mistake could cause serious damage, the legal protection of a limited company can be worth it on its own.

It is not a magic shield — banks often ask directors to personally guarantee loans, and you are still liable for your own negligence — but it draws a line that does not exist for a sole trader.

Proper public liability insurance matters either way, so do not treat going limited as a replacement for cover.

What about CIS and VAT?

Both structures work under CIS. If you are a subcontractor, deductions still apply whether you are a sole trader or a limited company — though a limited company can reclaim CIS deductions through payroll, which can help cash flow.

VAT works the same for both. Once your turnover crosses the registration threshold, you have to register regardless of structure. If you are anywhere near it, read up on the VAT turnover trap before it catches you out.

So which should you choose?

Stay a sole trader if:

Your profit is modest and the tax saving would be small
You want the least possible admin
You are just starting out and want to keep things simple

Consider a limited company if:

Your profit is consistently into higher-rate territory
You want the liability protection for higher-risk work
You are happy to pay an accountant to handle the extra filings
You are planning to grow, take on staff, or win bigger contracts

The honest bottom line

There is no universal right answer. The sweet spot for going limited is usually "my profit is high enough that the tax saving beats the extra cost and hassle."

If you are not sure where you sit, get a quick steer from an accountant before you change anything — switching structure is easy to do and annoying to undo. And whichever route you choose, keeping clean records and getting your invoices out on time matters far more to your bottom line than the structure on the letterhead.
