Sole Trader vs Limited Company: The Break-Even Profit Point 2026/27
Below a certain level of annual profit, operating as a sole trader is simpler and no more expensive in tax terms than running a limited company. Above it, incorporating usually starts to save money. Here is the break-even point for 2026/27.
Why there is no single "break-even number"
The comparison depends entirely on how much profit you actually spend versus retain. A limited company's core advantage is the gap between Corporation Tax (19-25%) and the combined Income Tax plus Class 4 National Insurance a sole trader pays on the same profit — but that gap only translates into a real saving on the portion of profit you can afford to leave inside the company rather than extract to live on.

| Structure | Tax and NI/dividend tax | Approximate net available |
|---|---|---|
| Sole trader | Income Tax + Class 4 NI on £50,000 profit | ~£37,000-£38,000 |
| Ltd company, small salary + rest as dividends, all extracted | 19% Corporation Tax + dividend tax on distributed profit | ~£37,000-£39,000 (before accountancy costs) |
Once £800-£1,200 of extra accountancy and filing costs for the limited company are deducted, the two structures land close to each other at this profit level and full extraction — the limited company is not clearly worthwhile purely on tax grounds here.

| Structure | What happens |
|---|---|
| Sole trader | Full £80,000 taxed as profit in the year it is earned — pushes a large chunk into the 40% band plus 2% NI |
| Ltd company | Corporation Tax (19%-25% marginal) on the full £80,000; only the £45,000 actually extracted is taxed again as salary/dividends; the retained ~£19,000-£24,000 stays inside the company taxed just once at Corporation Tax rates |
Here the limited company clearly wins, because a meaningful amount of profit is retained rather than extracted, avoiding a second layer of higher-rate personal tax on money you do not need immediately.
Practical takeaway
If you expect to draw out most or all of your profit to live on each year, the tax case for incorporating is often weaker than assumed, and the extra administrative burden may not be worth it below roughly £40,000-£50,000 of profit. If you can leave a meaningful surplus inside the business — building reserves, reinvesting, or simply not needing all the profit immediately — a limited company structure typically starts paying for itself well before profit reaches six figures.

At what profit level does a limited company become more tax-efficient than a sole trader?
For many typical small businesses, the tax-saving crossover generally starts to appear somewhere in the region of £30,000-£40,000 of annual profit, though the exact figure depends heavily on how much you actually need to draw out of the business each year versus retain within it — a limited company only saves tax on profit you can afford to leave inside the company rather than take out as salary and dividends.
Why doesn't a limited company always save tax at higher profit?
Because the tax saving from incorporating comes primarily from paying Corporation Tax (19-25%) on retained profit instead of Income Tax and Class 4 National Insurance on the same profit as a sole trader — but as soon as you extract that profit from the company as salary or dividends, it is taxed again (dividend tax, or Income Tax and employer/employee NI on salary), so the advantage shrinks or disappears if you need to take most of the profit out to live on each year.
What is the sole trader tax position on £50,000 profit in 2026/27?
A sole trader with £50,000 profit pays Income Tax on the amount above the £12,570 Personal Allowance (20% up to £50,270 of total income, 40% above) plus Class 4 National Insurance (6% between £12,570 and £50,270, 2% above), giving a combined tax and NI bill in the region of £12,000-£13,000, leaving roughly £37,000-£38,000 net.
What is the limited company position on the same £50,000 profit if all of it is extracted?
A limited company pays 19% Corporation Tax on profits up to £50,000 (small profits rate), leaving around £40,500 to distribute. If the director takes a small salary (up to the National Insurance threshold) plus the rest as dividends, they pay dividend tax at 8.75%/33.75%/39.35% depending on their band on amounts above the £500 dividend allowance — for many owner-managers extracting the full amount, the total tax (Corporation Tax plus dividend tax) ends up broadly similar to, or only modestly better than, the sole trader position at this profit level, once the extra accounting and administrative costs of running a company are factored in.
Where does the limited company advantage become clearer?
The advantage becomes clearer where you can retain a meaningful chunk of profit inside the company rather than extracting it all — for example, building up reserves for future investment, or where profit significantly exceeds what you need to live on, since retained profit is only taxed at 19-25% Corporation Tax rather than being pushed through higher-rate Income Tax and Class 4 NI as a sole trader.
Does the Employment Allowance change the comparison for a limited company?
It can, for companies with more than one employee (a single director-shareholder company generally cannot claim the Employment Allowance if the director is the only employee paid above the secondary threshold), reducing employer National Insurance for qualifying small companies with additional staff, which slightly improves the case for incorporating where you also employ others.
What non-tax costs should I weigh against the tax saving?
Running a limited company brings extra costs and obligations a sole trader does not have: annual accounts and a Confirmation Statement filed at Companies House, generally more complex accountancy fees, statutory record-keeping, and public disclosure of some financial information — these costs (often £600-£1,500+ a year in accountancy fees alone) should be netted off against any modest tax saving before deciding incorporation is worthwhile.
Is the break-even point the same for every trade and personal circumstance?
No — it varies with how much of the profit you need to extract to live on, whether you have other income (which affects your marginal rate as a sole trader), whether a spouse can also be a shareholder to use a second set of dividend allowances and tax bands, and the specific accountancy costs quoted for your business, so the £30,000-£40,000 range is a general guide rather than a precise figure for every situation.
