Sole Trader vs Limited Company in 2026/27: Which Structure Actually Saves You Tax Now

The maths on incorporating has shifted in 2026/27. Dividend tax rose on 6 April 2026, and according to Sleek's tax comparison, the break-even profit level where a limited company starts saving tax versus staying a sole trader now sits around £50,000 for most owners — meaningfully higher than in previous years.

What changed

Dividend tax rates for 2026/27 are now 10.75% at basic rate, 35.75% at higher rate, and 39.35% at additional rate, both the basic and higher rates having risen by 2 percentage points from 6 April 2026, per ByteStart's dividend tax guide. The dividend allowance remains just £500. Corporation tax, meanwhile, is unchanged at 19% for 2026/27, according to Debitam.

The result: the tax saving from extracting profit as dividends through a limited company, rather than paying income tax and National Insurance as a sole trader, has narrowed considerably.

The headline finding

Per IT Contracting's analysis, a sole director who extracts all company profits immediately now takes home more as a sole trader than as a limited company director at every profit level — with one notable exception: a director who employs at least one other person can use the Employment Allowance to eliminate employer National Insurance on their own salary, restoring the limited company advantage up to roughly £26,200 in company profit.

Why people still incorporate

Tax isn't the only reason to run a limited company. Limited liability protection, credibility with certain clients (particularly larger corporates and public sector contracts), and the ability to retain profits in the company at the 19% corporation tax rate rather than drawing everything out immediately, can all still make incorporation worthwhile — especially for businesses reinvesting profit rather than living off it month to month.

Checklist: deciding which structure fits your business

• Estimate your annual profit realistically, not optimistically — the crossover point matters more at higher profit levels.
• Check whether you employ anyone else — this materially changes the limited company maths via the Employment Allowance.
• Decide whether you need to retain profit in the business for reinvestment, rather than drawing it all out as income — retained profit taxed at 19% corporation tax can be more efficient than extracting everything immediately.
• Factor in non-tax reasons: limited liability, client perception, and pension contribution flexibility (employer pension contributions from a limited company are usually more tax-efficient than personal contributions as a sole trader).
• Get a specific calculation from an accountant rather than relying on general rules of thumb — the Employment Allowance threshold and dividend tax changes mean older advice may be out of date.
• Review annually — thresholds and dividend tax rates have moved multiple times in recent years and are likely to keep moving.

International comparison

The UK's approach — separate corporation tax and personal dividend tax, with a relatively low headline corporation tax rate of 19% — differs from the US, where pass-through entities like S-corps let many small business owners avoid a separate corporate tax layer entirely, and from Australia, where the company tax rate for small businesses is 25% but franking credits reduce double taxation on dividends in a different way to the UK's dividend allowance system.
