5 Reasons to Stay as a Sole Trader (Even When Your Profits Are High)

Staying a sole trader can be the right choice even at high profit levels, because the tax saving from incorporating is often smaller than expected once dividend tax, accountancy costs and administration are taken into account. The question of sole trader vs limited company in the UK in 2026 is rarely settled by profit alone. For many self-employed people earning well above the point where "should I go limited" first comes up, the practical and financial case for staying unincorporated remains strong. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, finds incorporation is not always the winner. This article sets out five reasons a high-earning sole trader might reasonably stay put, with the figures behind each one.

Key Takeaways

• The 2026/27 dividend tax rates rose to 10.75% (basic), 35.75% (higher) and 39.35% (additional), narrowing the tax gap between a sole trader and a limited company owner.
• The dividend allowance is just £500 in 2026/27, so most extracted profit is taxed from the first pound above salary.
• A limited company must file annual accounts and a Corporation Tax return, and its accounts are published on the public Companies House register.
• Sole traders keep 100% of their after-tax profit personally, with no rule against drawing money whenever they wish.
• Incorporation typically only produces a clear net saving once profits are sustained and profit is retained in the company rather than fully withdrawn.

Does staying a sole trader cost more tax in 2026/27?

Staying a sole trader does not automatically cost more tax, because the dividend tax rise from 6 April 2026 has reduced the headline advantage of a limited company. A sole trader pays Income Tax and Class 4 National Insurance on profits, while a company owner pays Corporation Tax and then dividend tax on money extracted. With dividend rates now at 10.75%, 35.75% and 39.35% and a dividend allowance of only £500, the combined company-plus-personal tax on withdrawn profit is much closer to sole trader tax than it was a few years ago.

Consider a self-employed consultant with £80,000 taxable profit. As a sole trader they pay Income Tax and Class 4 NIC personally. A limited company earning the same £80,000 pays Corporation Tax first, and the director then pays dividend tax at 35.75% on most of what they draw. Once accountancy fees and the extra filing burden are added, the net saving in this range is often only a few hundred to a couple of thousand pounds, not the transformative figure many expect.

How much simpler is sole trader admin?

Sole trader administration is significantly lighter, because a sole trader does not file company accounts, a Corporation Tax return, or confirmation statements at Companies House. A limited company must prepare statutory accounts, submit a Corporation Tax return to HMRC, file annual accounts and a confirmation statement with Companies House, and operate a payroll if the director takes a salary. Each of those obligations carries a deadline, a potential penalty, and usually a higher accountancy fee.

A sole trader's core obligation is a single annual Self-Assessment tax return. Note that Making Tax Digital for Income Tax is now live: from 6 April 2026, sole traders and landlords with qualifying income above £50,000 must keep digital records and submit quarterly updates plus a final declaration by 31 January. Even with these updates, sole trader compliance remains simpler and cheaper to run than a company's dual reporting to both HMRC and Companies House.

The comparison only holds once you know what a company would actually pay, which our guide to corporation tax sets out rate by rate.

Do sole traders have more privacy than limited companies?

Sole traders keep their financial affairs private, because they do not file public accounts, whereas a limited company's accounts and director details appear on the free, publicly searchable Companies House register. Anyone, including competitors, clients and suppliers, can view a company's filed accounts and see indicators of its size and financial position. For a self-employed professional who values discretion, that public exposure is a genuine drawback of incorporation. A sole trader's income is disclosed only to HMRC.

Can sole traders access their profits more freely?

Sole traders can access their money freely, because business profit belongs to them personally with no legal separation between the individual and the business. A sole trader can move money between business and personal accounts at any time. A company's money, by contrast, belongs to the company, and a director must extract it correctly as salary, dividend or a repaid loan. Taking money incorrectly can create an overdrawn director's loan account, which can trigger a temporary Corporation Tax charge under the close company rules and a benefit-in-kind charge. For someone who wants uncomplicated access to their own earnings, sole trader status is far simpler.

When is incorporation still worth it?

Incorporation still makes sense when profits are high and sustained and, crucially, when the owner does not need to withdraw all of the profit. A company's main advantage now lies in retaining profit inside the business taxed only at Corporation Tax, deferring the personal dividend tax until funds are drawn in a later year. Limited liability, pension planning through employer contributions, and a more saleable business structure can also tip the balance. The wider position is set out in our guide to sole trader vs limited company.

Frequently Asked Questions

Is it better to be a sole trader or limited company in 2026?

Neither is automatically better in 2026. A sole trader benefits from simpler admin, privacy and free access to profits, while a limited company can save tax where profit is retained rather than fully withdrawn. Following the 2026/27 dividend tax rise to 10.75%, 35.75% and 39.35%, the tax gap has narrowed, so the right answer depends on your profit level and how much you draw.

At what profit should a sole trader consider going limited?

There is no single profit figure at which incorporation always wins. Many self-employed people begin seriously reviewing it once profits are comfortably into the higher-rate band and sustained year on year, but the deciding factor is whether you can leave profit inside the company. If you need to withdraw everything you earn, the tax advantage of incorporating is often small once fees are counted.

Do sole traders pay more National Insurance than company directors?

Sole traders pay Class 4 National Insurance on their profits, while company directors typically pay National Insurance only on salary, not on dividends. This is one reason a company can appear cheaper. However, the dividend tax charged on extracted company profit offsets much of that National Insurance saving, so the overall difference in 2026/27 is smaller than the headline suggests.

Does a sole trader have to publish accounts?

No. A sole trader does not file or publish accounts anywhere. A sole trader reports profit privately to HMRC through Self-Assessment. Only limited companies must file statutory accounts at Companies House, where they become part of the free public register that anyone can search, including competitors and clients.

Can I switch from sole trader to limited company later?

Yes. You can incorporate at any time, and many people deliberately start as a sole trader and switch once profits justify it. Incorporating later is straightforward and can allow you to claim relief on transferring business goodwill and assets, so there is rarely a penalty for waiting until the numbers clearly support the change.

Before making the switch, get the numbers modelled properly against your actual income and spending. The right structure is the one that leaves you with the most after tax, hassle and cost, not simply the one with a company name.
