Sole Trader vs Limited Company in 2026: Where's the Real Break-Even Point?

The old rule of thumb — incorporate once you're earning decent money — no longer holds up cleanly in 2026. Recent dividend tax changes have narrowed the gap between trading as a sole trader and running a limited company, and the "sweet spot" for switching is now much tighter than it used to be.

What changed on 6 April 2026

From 6 April 2026, dividend tax rates rose for both basic and higher-rate taxpayers: the basic rate increased from 8.75% to 10.75%, and the higher rate from 33.75% to 35.75%, according to Wright Vigar's 2026 analysis. That erodes much of the historic advantage of paying yourself through dividends rather than a salary, which was the main reason incorporation used to save money so reliably.

Where the numbers land now

At roughly £60,000 of annual profit, a sole trader faces around £10,800 in Income Tax plus about £3,500 in Class 4 National Insurance — a total of roughly £14,300, according to Wright Vigar's worked example. A limited company director taking a small tax-efficient salary and the rest as dividends might instead pay around £7,111 in Corporation Tax and £2,600 in dividend tax — roughly £9,711 total, a saving of over £4,500 a year at this profit level.

Below about £40,000–£50,000 of profit, though, Seed Formations and other accountants note the extra £800–£1,500+ a year in accountancy, payroll and filing costs typically outweighs the tax saving, meaning sole trader status remains simpler and often cheaper overall. The genuine "sweet spot" for incorporation currently sits around £55,000–£60,000 of profit, narrower than in previous years, per Wright Vigar.

It isn't only about tax

A limited company also gives you limited liability — your personal assets are generally protected if the business runs into debt or is sued, unlike as a sole trader where you're personally on the hook, according to The Accounting Crew. Some business owners incorporate for this protection alone, even below the tax break-even point.

There's also a Making Tax Digital angle: limited companies currently sit outside MTD for Income Tax, so incorporating can temporarily sidestep the quarterly digital reporting now mandatory for sole traders earning over £50,000, per 1Office.

Checklist: deciding whether to incorporate

• Calculate your actual profit for the current tax year, not turnover — the comparison only works on profit after expenses.
• Compare your Income Tax plus Class 4 NI bill as a sole trader against estimated Corporation Tax plus dividend tax as a company, using an up-to-date sole trader vs limited company calculator.
• Factor in the extra £800–£1,500+ annual cost of company accounts, payroll and a confirmation statement.
• Weigh limited liability protection separately from the pure tax calculation — it may justify incorporating even without a tax saving.
• Consider the MTD reporting burden if you're a sole trader already over, or approaching, the £50,000 threshold.
• Get a personalised calculation from a qualified accountant before switching — thresholds shift every tax year.
