If you’re weighing up sole trader vs limited company, the honest answer is that the tax gap between the two has narrowed sharply since April 2026, and for plenty of small business owners it’s now closer to a coin toss than a clear win. Dividend tax rates rose again this April, employer National Insurance is higher than it’s been in years, and Companies House now demands proof of who you actually are before you can act as a director. This guide walks through where each structure wins, using current figures rather than the older comparisons still floating around online.
Sole trader vs limited company: the quick answer
There’s no universal winner here, and anyone telling you there is hasn’t run the numbers for 2026/27. Broadly speaking, a sole trader structure suits people trading alone with modest profits and no interest in shareholders or complex admin. A limited company suits businesses that need to limit personal liability, look more established to clients or lenders, or have grown to a profit level where the tax mechanics tip in their favour.
The catch is that the profit level where those mechanics tip has moved. Before the dividend rate rise, incorporating was often worth it once profits passed roughly £30,000 to £40,000. Now, depending on whether your company can claim the Employment Allowance, the crossover point sits somewhere between £26,000 and £30,000 of profit, and at higher profit levels the gap can actually swing back in the sole trader’s favour. We’ll show the working below rather than asking you to take our word for it.
What’s the difference between sole trader and limited company?
The core distinction is legal identity. As a sole trader, you and your business are the same person in the eyes of the law. There’s no separation between your personal finances and the business’s finances, and you keep all the profit after tax, but you’re also personally on the hook for any business debts.
A limited company is a separate legal entity. It owns its own assets, signs its own contracts and is liable for its own debts. You become a director (and usually a shareholder) rather than the business itself, and you extract money from the company through salary, dividends, or both.
A few practical differences follow from that split:
- Setup: registering as self-employed takes minutes online; incorporating a company involves Companies House, a registered office address, and now an identity check
- Naming: sole traders can trade under almost any name that isn’t already trademarked; company names must be unique on the Companies House register
- Records: sole traders keep records for Self Assessment; limited companies keep statutory accounting records and file annual accounts
- Money: a sole trader’s business income is their income; a limited company’s profit belongs to the company until it’s paid out as salary or dividends
Sole trader or limited company: how the tax bill compares in 2026/27
This is where the decision usually gets made, and it’s also where most older articles are now out of date. The Autumn Budget 2025 raised dividend tax rates from 6 April 2026, and that change alone reshapes the comparison.
How sole traders are taxed
As a sole trader, all your business profit is taxed as personal income through Self Assessment. For 2026/27:
- Personal Allowance: £12,570, tax-free (frozen since 2021/22, and it tapers away entirely once total income passes £125,140)
- Basic rate: 20% on profit between £12,570 and £50,270
- Higher rate: 40% on profit between £50,270 and £125,140
- Additional rate: 45% on profit above £125,140
On top of Income Tax, you pay Class 4 National Insurance at 8% on profits between £12,570 and £50,270, and 2% above that, according to GOV.UK. Class 2 NI was scrapped from 6 April 2024, so that’s one less charge sole traders need to think about.
How limited companies are taxed
A limited company pays Corporation Tax on its profits before anything reaches you personally. The rates for 2026/27:
- 19% (small profits rate) on profits up to £50,000
- 25% (main rate) on profits above £250,000
- Marginal relief tapers the effective rate between those two thresholds, working out at roughly 26.5% on each additional pound within the band, according to HMRC’s guidance
Once the company has paid Corporation Tax, you draw money out as a director’s salary (taxed like any employee’s wages, with Income Tax and National Insurance) and dividends (taxed separately, and more favourably, once they’re above the £500 dividend allowance). From 6 April 2026, dividend tax rates rose to 10.75% at the basic rate and 35.75% at the higher rate, with the additional rate unchanged at 39.35%, according to GOV.UK.
Your company also pays employer National Insurance at 15% on any salary above £5,000 a year, unless you qualify for the Employment Allowance, which can wipe out up to £10,500 of that cost annually. Here’s the catch most sole-director companies run into: you can’t claim the Employment Allowance if you’re the company’s only director and you don’t employ anyone else, according to HMRC’s eligibility rules.
The worked examples: where the crossover actually sits
Below are simplified figures for someone taking a standard tax-efficient salary of £12,570 and the rest as dividends, assuming no other income, no pension contributions and standard England and Northern Ireland rates. Scotland has different Income Tax bands, so Scottish sole traders and directors should adjust accordingly.
| Profit | Sole trader (net) | Limited company, solo director, no Employment Allowance (net) | Limited company, with Employment Allowance (net) |
| £30,000 | £25,120 | £24,403 | £25,224 |
| £50,000 | £39,520 | £38,862 | £39,683 |
| £80,000 | £56,957 | £55,765 | £56,301 |
A few things jump out. If you’re a solo operator with no staff, meaning no access to the Employment Allowance, the sole trader route now comes out ahead at every profit level shown, reversing the advantage incorporation used to offer. That’s the direct result of employer National Insurance rising to 15% on a lower threshold, combined with the dividend tax increase.
If your company does qualify for the Employment Allowance, because you employ someone else alongside yourself, incorporating pulls slightly ahead around the £30,000 to £50,000 profit band. But look at the £80,000 row: even with the Employment Allowance, the sole trader figure creeps back on top. The higher dividend rate and the marginal Corporation Tax band eat into the advantage as profits climb, so the gap that used to widen in the company’s favour at higher earnings has flattened out and, in this scenario, reversed again.
None of this accounts for pension contributions, which companies can pay directly from pre-tax profit at no personal tax cost, a lever that can meaningfully shift the numbers if retirement saving is a priority. It’s also worth remembering that tax rules change most years, so treat these figures as a snapshot rather than a permanent ranking, and run your own numbers or speak to an accountant before deciding.
Liability: what happens if the business owes money
This is the factor tax calculators can’t capture, and for a lot of business owners it matters more than a few hundred pounds of annual tax saving.
As a sole trader, you have unlimited personal liability. If the business can’t pay a debt, a supplier invoice, or a legal claim, creditors can pursue your personal assets, including your savings and potentially your home, to settle it. There’s no legal wall between you and the business.
A limited company offers limited liability. Provided you haven’t given a personal guarantee (common for company directors taking out loans or leases) or acted fraudulently, your personal assets are generally protected if the company runs into debt it can’t pay. The company’s liability is limited to what it owns.
This distinction matters most if your work carries genuine financial risk: large contracts, physical products that could cause damage, client work where mistakes are costly, or any situation where a lawsuit is a realistic possibility. If you’re a freelance writer with low-risk contracts and no significant assets on the line, the liability argument carries less weight.
Credibility: does a limited company look more serious?
Rightly or wrongly, some clients, particularly larger businesses and public sector organisations, prefer to work with limited companies. It can signal permanence and professionalism, and some procurement processes exclude sole traders outright.
That said, plenty of established sole traders, especially tradespeople and consultants with strong reputations, trade successfully without ever incorporating. If your client base is mostly individuals or small businesses who care about your work rather than your company structure, this factor may not move the needle much.
Admin burden and running costs
Sole trading is administratively lighter. You register once, keep records of income and expenses, and file one Self Assessment return a year by 31 January. Many sole traders manage this themselves without an accountant, at least in the early years.
Running a limited company brings more obligations:
- Annual accounts filed with Companies House
- Corporation Tax return (CT600) filed with HMRC, alongside the accounts
- Confirmation statement filed at least once a year, confirming company details are accurate
- Payroll if you take a salary, with Real Time Information submissions to HMRC
- Separate business bank account, which most banks require for limited companies
Most directors use an accountant for at least the annual accounts and Corporation Tax return, which typically adds a few hundred pounds a year to running costs, though prices vary widely depending on the complexity of your business.
Companies House disclosure: what becomes public
This is a genuine trade-off that sole traders don’t face. A limited company’s information is published on the public Companies House register, and anyone can look it up for free.
That includes your annual accounts (even abridged ones show some financial detail), your registered office address, the names of directors and shareholders, and details of anyone classed as a Person with Significant Control (PSC), generally someone who owns more than 25% of the company’s shares or voting rights. If privacy matters to you, particularly if you work from home and haven’t set up a separate registered office, this is worth thinking through before incorporating.
Sole traders, by contrast, have no equivalent public disclosure requirement beyond what’s needed for tax purposes, which stays with HMRC rather than a public register.
The new identity verification duty for directors
This is a genuinely new requirement that most older comparison articles won’t mention, because it only became mandatory partway through 2025 and 2026.
Under the Economic Crime and Corporate Transparency Act, Companies House now requires identity verification for every company director and PSC. It became compulsory for all new directors and new company incorporations from 18 November 2025. If you’re already a director of an existing company, you have until 18 November 2026 to complete verification, according to Companies House’s transition timetable.
You can verify either directly through GOV.UK One Login or via an Authorised Corporate Service Provider, such as an accountant registered for the role. Failing to verify is treated seriously: it’s a criminal offence, and unverified directors and companies both risk financial penalties, with fines reported as high as £5,000, plus the possibility of the company being struck off the register if the situation isn’t resolved.
Sole traders have no equivalent requirement. Registering for Self Assessment still asks for identity details, but there’s no separate verification duty or public register entry to maintain.
When to switch from sole trader to limited company
There’s rarely one single trigger, but these are the questions worth asking yourself.
Are your profits consistently above the crossover point?
Based on the figures above, that’s roughly £26,000 to £30,000 if you’d qualify for the Employment Allowance, though solo operators without staff may find sole trading remains cheaper well beyond that.
Do you need liability protection?
If a single bad contract or mistake could threaten your personal assets, that risk can outweigh a modest tax saving either way.
Are clients or contracts pushing you toward it?
Some larger clients and public sector contracts require a limited company. If that’s blocking work you’d otherwise win, it settles the decision for you.
Can you handle, or afford, the extra admin?
Annual accounts, a CT600, payroll and a confirmation statement add real time and cost. If you’re not ready to take that on or pay someone else to, staying a sole trader for now may be the more sensible choice.
Do you want to retain profit in the business?
Companies can leave profit undrawn and taxed only at Corporation Tax rates, useful if you don’t need to withdraw everything you earn each year. Sole traders are taxed on all their profit regardless of whether they draw it out.
There’s no rule that says you must incorporate at a specific turnover figure, and switching later, once profits and priorities are clearer, is entirely normal. Plenty of successful businesses start as sole traders and incorporate a few years in, once the numbers and the workload both justify it.
FAQs
Is it better to be a sole trader or limited company for tax?
It depends on your profit level and whether your company qualifies for the Employment Allowance. For solo directors without staff, sole trading is now often cheaper across most profit levels following the 2026 dividend tax rise. With the Employment Allowance, a limited company can save a modest amount roughly between £26,000 and £65,000 of profit, though the gap narrows again at higher earnings.
What is the difference between sole trader and limited company liability?
A sole trader has unlimited personal liability, meaning personal assets can be used to settle business debts. A limited company is a separate legal entity, so liability is generally limited to what the company owns, provided no personal guarantees were given and there’s no fraud involved.
How much profit before it’s worth switching to a limited company?
There’s no fixed figure, but based on 2026/27 rates, incorporating tends to make the most tax sense somewhere between £26,000 and £30,000 of profit if your company can claim the Employment Allowance. Below that, or without the allowance, sole trading is often still the cheaper route.
Do I pay less tax as a limited company in 2026?
Not automatically. The dividend tax rises and higher employer National Insurance introduced by April 2026 have narrowed, and in some cases reversed, the tax advantage limited companies used to hold, particularly for directors without staff. Run the numbers for your specific profit level rather than assuming incorporation saves money.
Can I switch from sole trader to limited company later?
Yes, and it’s a common path. You register a new company with Companies House, transfer the business (which may have Capital Gains Tax implications depending on what assets move across), and stop trading as a sole trader once the switch is complete. Speaking to an accountant before the transfer helps avoid unexpected tax charges.
Do limited companies have to make their accounts public?
Yes. Annual accounts are filed with Companies House and published on the public register, along with director and shareholder details. Sole traders have no equivalent public disclosure requirement.
What is the identity verification requirement for company directors?
Since 18 November 2025, all new company directors and Persons with Significant Control must verify their identity with Companies House, either through GOV.UK One Login or an authorised agent. Existing directors have until 18 November 2026 to complete this, and failing to do so is a criminal offence that can lead to fines or the company being struck off.
Is a limited company more credible than a sole trader?
It can be, particularly with larger clients, public sector contracts or lenders who see incorporation as a sign of permanence. Many sole traders build strong reputations without it, though, so the impact depends heavily on your industry and client base.
