Sole Trader or Limited Company: Which Is Right for Your Business

Should you trade as a sole trader or limited company? It is the question we hear most often at this time of year, usually from someone who has just finished their first self assessment and wondered whether a company would have left more money in their pocket. The honest answer is that it depends on your profit, your plans, and your appetite for paperwork, and the summer months after the tax year ends are the ideal time to weigh it up properly.

How the two structures actually differ

A sole trader and their business are legally the same thing. You keep all the profit, you pay income tax and National Insurance on it through self assessment, and you are personally responsible for any business debts. Registration is quick and free, as the GOV.UK guide to setting up a business sets out, and the ongoing admin is light.

“

Neither route is automatically better, and the right answer changes as a business grows.

What follows is the practical comparison we walk clients through, using the rates that apply for 2026-27.

A limited company is a separate legal entity. The company earns the profit, pays corporation tax on it, and you take money out as salary, dividends, or a mix of both. Your personal liability is normally limited to what you put in, which matters a great deal if your work carries financial risk or you sign contracts worth more than you could cover personally.

The price of that protection is formality. Companies file annual accounts and a confirmation statement with Companies House, run a payroll for any salary, and keep statutory registers. The official guidance on setting up a limited company lists the registration steps, but the ongoing obligations are where most owners need support.

Sole trader or limited company: the tax picture in 2026-27

For 2026-27, sole traders pay income tax at 20%, 40%, or 45% on profits above the £12,570 personal allowance, plus Class 4 National Insurance at 6% between £12,570 and £50,270 and 2% above that. Companies pay corporation tax at 19% on profits up to £50,000, rising on a sliding scale to 25% above £250,000.

At a glance	Sole trader	Limited company
Legal status	You and the business are one	Separate legal entity
Tax on profits	Income tax at 20%, 40%, or 45%	Corporation tax at 19% to 25%
National Insurance	Class 4 at 6%, then 2%	None on dividends; employer NI on salary
Personal liability	Unlimited	Normally limited to your stake
Annual admin	One self assessment return	Accounts, confirmation statement, payroll
Privacy	No public record	Accounts and directors public

The headline rates flatter companies, but dividends carry their own tax once they leave the business. With the dividend allowance now just £500, the overall saving from incorporating is much smaller than it was a decade ago. As a rough guide, the tax case for a company starts to look interesting once profits pass £50,000 and gets stronger if you can leave some profit in the business rather than drawing everything.

Numbers like these are exactly why a generic online calculator is not enough. Our accounting services in Widnes include a side-by-side comparison using your real figures, so you can see what each structure would have cost you last year before you commit to anything.

What Making Tax Digital changes from April 2026

A newer factor has entered the decision this year. Since 6 April 2026, sole traders and landlords with combined gross income over £50,000 must keep digital records and send quarterly updates to HMRC under Making Tax Digital for Income Tax. The threshold drops to £30,000 in April 2027. Limited companies are outside this regime for now, which has nudged some higher-earning sole traders towards incorporating.

Switching structure purely to dodge quarterly reporting rarely makes sense on its own, because company admin replaces one set of obligations with another. What matters is having clean digital records either way. Our book-keeping service sets clients up on compliant software so the quarterly updates become a non-event rather than a deadline to dread.

Paying yourself: the day-to-day difference

As a sole trader, the business’s money is your money. You draw what you need, when you need it, and the tax is calculated on your profits at the year end regardless of what you took out. That freedom is convenient, but it makes the discipline of setting aside tax entirely your responsibility.

A company director draws money in defined ways: a salary through a registered payroll, dividends declared from available profits, or repayments of money lent to the company. Dividends paid when there are no profits to cover them can be reclassified by HMRC, with messy consequences, so the paperwork has to be kept straight. Our payroll services run director payrolls for exactly this reason.

The practical difference shows up in lean months. A sole trader can simply take less, while a director needs to check that drawings stay within the rules. Neither is a problem with good records, and both are a problem without them.

Questions to ask before you decide

Four questions cover most of it. Work through them honestly and the right structure usually announces itself.

Question one

What is your profit?

Under about £30,000, the costs of running a company usually outweigh the tax saving. Past £50,000, the case strengthens, especially if profit can stay in the business.

Question two

What is your risk?

Limited liability is worth paying for in some trades and irrelevant in others. Think about what would happen if a big contract went wrong tomorrow.

Question three

Who are your customers?

Some larger firms and agencies prefer dealing with companies, and a few insist on it, particularly in construction, IT, and consultancy.

Question four

How is your admin?

If keeping receipts in order is already a struggle, the extra filings of a company will need professional support behind them.

Pensions and benefits deserve a thought too. A company can make employer pension contributions for its director, which are usually deductible for corporation tax and sit outside the dividend rules altogether. Sole traders make personal contributions instead, with relief through self assessment. For owners in their fifties planning an exit, this difference alone can swing the decision.

Think about image and credit as well. A company name on Companies House can help when applying for trade accounts or finance, but your accounts become publicly visible.

There is no permanent lock-in either way. Plenty of our clients start as sole traders, build the business, and incorporate once the profits justify it. Moving assets and goodwill into a company has tax consequences of its own, so the change is best planned rather than rushed in a January panic.

Frequently Asked Questions

At what profit level is a limited company worth it?

There is no single number, but below roughly £30,000 of profit the saving rarely covers the extra accountancy and admin costs. Between £30,000 and £50,000 it is marginal. Above £50,000, and especially where profit can be retained in the company, the case usually strengthens. We always run the comparison on real figures.

Can I switch from sole trader to limited company mid-year?

Yes. You can incorporate at any point, register the company with Companies House, and tell HMRC your sole trade has ceased. You will file a final self assessment covering the sole trader period and the company accounts begin from incorporation. Timing it near the tax year end keeps things tidier.

Do I pay less National Insurance through a company?

Often, yes. A director taking a small salary plus dividends pays no National Insurance on the dividends, whereas a sole trader pays Class 4 on all profits above £12,570. The company may pay employer’s National Insurance on salary above the threshold, so the structure of how you pay yourself matters.

Will my accounts really be public as a limited company?

Yes, although small companies file abridged accounts that show limited detail, typically a balance sheet without a full profit and loss account. Your registered office address, director names, and filing history are also public. Sole traders have no equivalent public record.

Does being a sole trader look less professional?

Not in most trades. Customers care about the quality of the work, the price, and whether you turn up. That said, some agencies, contractors, and corporate clients prefer or require a limited company, particularly in construction, IT, and consultancy, so check what your target customers expect.

What does it cost to run a limited company each year?

Budget for the £34 Companies House confirmation statement fee, accountancy fees for the annual accounts and corporation tax return, and payroll running costs if you take a salary. For a simple owner-managed company the total is usually a few hundred to around a thousand pounds a year.
