Search "UK company formation 2026" and you'll find dozens of articles describing a surge: entrepreneurs flocking to limited companies, online incorporation services booming, business registration reaching new heights. It's a tidy story. We think it's also only half true.
Companies House incorporation data, for the financial year ending March 2026 shows 815,277 new company incorporations, up 1.67% on the year before. That's growth, technically, but the year before, FYE2025, saw incorporations fall by 10% compared with FYE2024.
So the "record high" framing doing the rounds in some UK company formation coverage is really a modest recovery from a dip, not a runaway boom.
There's a second number that rarely makes it into the celebratory headlines: dissolutions rose 8.31% over the same period, to 787,120, roughly as many companies closed as opened, so the total register grew by just 0.53% in the most recent quarter alone.
We think that's the more honest story about UK company formation right now, not a wave of new business confidence, but a churn.
Two Real Reasons People Are Actually Incorporating
None of this means the underlying interest in limited companies is fake; it just has more specific causes than "entrepreneurs prefer it", and both cut in different directions.
The first is regulatory pressure, not choice.
Making Tax Digital (MTD) for Income Tax became mandatory in April 2026 for sole traders and landlords with earnings above £50,000. That means quarterly digital reporting to HMRC instead of one annual Self Assessment return. Limited companies fall outside this regime entirely, filing a single Corporation Tax return each year. For sole traders already stretched on admin, that alone is pushing serious conversations about the sole trader vs limited company decision — not because the tax bill improves, but because the paperwork does.
The second is that Companies House itself is getting more expensive and more demanding to deal with. Digital incorporation fees doubled from £50 to £100 in February 2026. Confirmation statement filing rose too, and since 18 November 2025, identity verification has been a legal requirement under the Economic Crime and Corporate Transparency Act, which is a real hurdle that simply didn't exist a year earlier, making Companies House incorporation slower for many first-time founders.
Incorporating in 2026 costs more money and more friction than it did in 2025, even as the volume of people choosing UK company formation edges back up. Companies House incorporation costs have simply risen faster than the appetite to use them has grown.
The Tax Case Everyone's Marketing Copy Ignores
Here's the part we think gets buried under the sole trader vs limited company SEO content: the financial argument for incorporating has actually gotten weaker in 2026, not stronger.
Dividend tax rates rose two percentage points from 6 April 2026, the basic rate from 8.75% to 10.75%, the higher rate from 33.75% to 35.75%.
The dividend allowance sits at just £500.
Several accountants we've seen writing on this topic now place the break-even point – the profit level where incorporating actually saves you money – somewhere between £50,000 and £60,000, meaningfully higher than the roughly £30,000 figure that used to circulate as conventional wisdom.
Below that threshold, several 2026 analyses of the sole trader vs limited company comparison now show a sole trader's take-home pay coming out roughly level with, or even ahead of, a limited company director's – once you account for accountancy costs, which typically run £800 to £2,000 a year higher for a company.
So the honest picture looks like this: MTD is pushing people toward incorporation for administrative relief, while the tax system is simultaneously pulling the financial incentive to incorporate downward. Those two forces don't point the same direction, and we think that tension is the real 2026 story, not the tidy "entrepreneurs are choosing limited companies" narrative that UK company formation services have an obvious commercial interest in promoting.
What We Think This Actually Means
We're not going to tell you whether to incorporate or settle the sole trader vs limited company question for you.
Anyone claiming there's a universal answer is usually selling something — often, quite literally, an incorporation service.
What we do think is worth saying plainly: if you're below roughly £40,000 to £50,000 in profit, the tax case for a limited company is thinner in 2026 than it's been in years, and the admin cost is real. If you're a sole trader edging past £50,000 and dreading quarterly MTD filings, incorporating might solve an administrative headache, even if it doesn't result in a significantly better tax bill. If you're already incorporated and comfortably above £60,000 profit, the numbers still tend to favour staying that way, regardless of how the original Companies House incorporation came about.
The broader pattern, though, is one we think founders and advisers should sit with. A structural change in tax policy (the dividend rate rise) and a structural change in reporting requirements (MTD) landed in the same tax year, pulling small business owners in opposite directions at once. Formation continued to increase, while dissolutions rose nearly as quickly, and a wave of UK company formation press coverage framed this as a story about entrepreneurial optimism.
We're not so sure it is, as it might just be a country's small businesses responding, quite rationally, to a tax and compliance system that changed the rules on them twice in the same year and to the wider forces shaping UK company formation trends more broadly.
