- A limited company is not automatically more tax-efficient in 2026/27, because dividend tax rose on 6 April 2026.
- The break-even point where a limited company saves tax now sits higher, roughly around the £50,000 profit mark for most owners.
- Tax is only part of the decision, since liability protection, credibility, and admin cost all matter alongside the numbers.
Sole trader vs limited company tax is genuinely profit-dependent in 2026, and a limited company is no longer the automatic winner. For most sole traders earning under £50,000 in profit, staying a sole trader is simpler and the tax saving from going limited is now small.
The reason is timing. Dividend tax rose on 6 April 2026, narrowing the gap that once made incorporation an easy call. You can still save tax as a limited company at higher profits, but the maths changed this year.
Sleek’s accounting services cover both structures, so you can pick the one that actually fits your numbers.
If you want the full pros and cons beyond tax, our sole trader vs limited company guide covers the whole comparison. This page focuses purely on the tax maths and the break-even point.
Sole trader or limited company: which is better for tax in 2026?
A limited company tends to win on tax once profits comfortably clear around £50,000, while below that the difference is often marginal after the 2026 dividend rise. The honest answer depends on your profit level and how much you draw.
Both structures tax the same underlying profit, just through different routes. A sole trader pays income tax and National Insurance on all profit. A limited company pays corporation tax first, then you pay personal tax on the salary and dividends you take out.
The 2 percentage point dividend rise from 6 April 2026 increased the cost of extracting profit from a company. That single change pushed the break-even point higher than it sat in previous years.
How sole traders are taxed
A sole trader pays income tax and Class 4 National Insurance on all business profit, with no separation between you and the business.
We cover this in full in our guide to how sole traders are taxed. For this comparison, the key point is that every pound of profit is taxed as personal income in the year you earn it, which is what the limited company route changes.
How limited companies are taxed (with the new 2026 dividend rates)
A limited company pays corporation tax on profit, then directors pay personal tax on what they withdraw as salary or dividends. This two-layer system is where the planning happens.
Corporation tax for 2026/27 works on a tiered basis:
Profit level | Corporation tax rate |
Up to £50,000 | 19% (small profits rate) |
£50,001 to £250,000 | Marginal relief, around 26.5% effective on the band |
Above £250,000 | 25% (main rate) |
After corporation tax, you extract profit. Most directors take a small salary plus dividends. The dividend allowance is £500, and dividend tax for 2026/27 is now 10.75% at the basic rate, 35.75% at the higher rate, and 39.35% at the additional rate.
Those basic and higher dividend rates rose by 2 points on 6 April 2026. That is the change that reshaped this comparison.

Worked examples: £30k, £50k and £80k profit
Real numbers make the decision clearer than rates alone. These examples assume a sole trader taxed fully on profit, and a director taking a salary up to the personal allowance plus dividends, using 2026/27 figures.
£30,000 profit
A sole trader pays roughly £3,486 income tax and around £1,046 Class 4 NI, totalling about £4,532. A limited company on the same profit pays 19% corporation tax, then modest dividend tax on the extracted balance. The combined company tax lands within a few hundred pounds of the sole trader figure. At this level, the saving rarely justifies the extra admin.
£50,000 profit
A sole trader pays around £7,486 income tax plus £2,246 Class 4 NI, totalling about £9,732. A limited company pays 19% corporation tax on the £50,000, then dividend tax on the post-tax profit drawn. The company route starts to edge ahead, but the gain is narrower than it was before April 2026.
£80,000 profit
This is where a limited company pulls clear. The sole trader pays 40% on profit above £50,270, while the company caps the first layer at corporation tax rates and spreads extraction across dividend bands. The saving becomes meaningful, often running into a few thousand pounds depending on how much you leave in the company.
The gap widens fastest when you do not need to draw all the profit, because money left in the company is only taxed at the corporation tax rate until you withdraw it.
Where’s the break-even point?
The break-even point in 2026/27 sits roughly around £50,000 of profit for most owners who draw most of what they earn. Below it, the tax difference is usually too small to outweigh the cost and admin of a company.
That threshold is higher than in previous years. The 2026 dividend rise shaved off part of the saving that used to appear at lower profits.
Two factors move the line:
- How much profit you actually withdraw, since retained profit stays cheaper.
- Whether you can split income with a spouse or use pension contributions.
For a sense of the running costs that factor into this decision, see our breakdown of the cost of running a limited company.
Beyond tax: liability, credibility and admin
Tax is only one part of the structure decision, and it often is not the deciding one. A limited company offers limited liability, separating your personal assets from business debts. A sole trader carries unlimited personal liability.
There are trade-offs in both directions:
- Credibility: a limited company can look more established to clients, lenders, and suppliers.
- Admin: companies file annual accounts, a corporation tax return, and a confirmation statement, which is more work than a single Self Assessment.
- Privacy: company directors’ details appear on the public register, whereas sole traders stay private.
- Cost: running a company usually means higher accountancy fees.
Many owners weigh credibility and liability as heavily as tax.
When (and how) to switch to a limited company
You should consider switching once profits sit consistently above the break-even point and you no longer need to draw every pound. The decision is about sustained profit, not a single strong year.
The switch follows a clear order:
- Confirm the move makes sense on your real profit and drawing pattern.
- Register a limited company at Companies House.
- Tell HMRC you have stopped trading as a sole trader and file a final Self Assessment.
- Transfer business assets, contracts, and bank arrangements into the company.
- Set up payroll if you plan to take a salary, and a dividend process.
Timing matters less than people fear. The transition can happen mid-year, and the first company year does not need to be perfect to be worthwhile.
When you are ready, you can register a limited company and have the setup handled for you.

FAQs on sole trader vs limited company tax
Is it always cheaper to be a limited company?
No. After the 6 April 2026 dividend tax rise, a limited company is only reliably cheaper once profits clear roughly £50,000 and you do not need to draw everything. Below that, the saving is often too small to outweigh the extra admin and accountancy cost, so many lower-profit sole traders are better off staying as they are.
Does going limited reduce my National Insurance?
Partly. A sole trader pays Class 4 NI on profit, while a director taking a low salary and dividends largely sidesteps personal NI on the dividend portion. The catch is that dividends now carry higher tax than before, so the NI saving is offset and the overall gain is smaller than it once looked.
How much profit do I need before incorporating?
Around £50,000 of sustained annual profit is a sensible trigger for most owners in 2026/27. The exact figure shifts with how much you withdraw and whether you split income with a spouse. A single high year is not enough, since the running costs of a company need consistent profit to be worthwhile.
Can I be a sole trader and a limited company at the same time?
The Personal Allowance for 2025/26 is £12,570. You pay no income tax on the first £12,570 of profit. However, National Insurance applies separately from a lower threshold — so sole traders with profit below £12,570 may owe no income tax but could still have Class 2 NI obligations. The Personal Allowance reduces above £100,000 total income and disappears at £125,140. Source: HMRC.
When do sole traders pay tax?
Yes. You can run one trade as a sole trader and operate a separate limited company for another, provided the activities are genuinely distinct. Each is taxed under its own rules, and you would file Self Assessment for the sole trade and company filings for the company. Keep the finances strictly separate to avoid HMRC questions.

What happens to my tax when I switch mid-year?
You file a final Self Assessment covering your sole trader profit up to the switch date, then the company is taxed separately from incorporation onward. The two periods do not overlap. Your first company year does not need to be a full twelve months, and an imperfect first year does not undo the benefit.
Do limited companies pay more in accountancy fees?
Generally yes. Companies need annual accounts, a corporation tax return, and a confirmation statement, which is more work than a single sole trader return. Those fees are a real cost in the break-even calculation, which is why a small tax saving at lower profits often disappears once you account for them.
