Sole trader vs limited company

Should I go limited?

It is one of the most common questions we hear from growing businesses in North Devon. There is no single right answer — but understanding the key differences will help you make the decision that is right for you.

The basics

Why it matters

As a sole trader, your business and personal finances are legally the same thing. That simplicity is great when you are starting out, but as your income grows it can mean a higher tax bill and greater personal financial risk.

Incorporating as a limited company creates a separate legal entity. That separation can bring tax advantages, limited liability protection and a more professional image — but it also comes with more administration and reporting obligations.

At this profit level, staying a sole trader keeps more in your pocket than incorporating would, once employer's National Insurance and dividend tax are both accounted for.

How this is worked out. Sole trader figures use the 2026/27 Income Tax bands (20% / 40% / 45%) and Class 4 National Insurance (6% / 2%) on the full profit. Limited company figures assume a director's salary of £12,570, employer's National Insurance on that salary above the £5,000 threshold with no Employment Allowance, 2026/27 Corporation Tax with marginal relief between £50,000 and £250,000, and the rest of the profit paid out as dividends and taxed at 2026/27 dividend rates (10.75% / 35.75% / 39.35%, £500 allowance). It assumes no other income, England, Wales or Northern Ireland rates, and a business run by one owner-director. Real numbers vary with expenses, pension contributions and personal circumstances.

Timing

When does going limited start to make sense?

There is no magic number, but many accountants suggest considering incorporation once your profits consistently exceed around £30,000–£40,000 per year. At that level the Corporation Tax rate and the ability to split income between salary and dividends can result in a meaningfully lower overall tax bill.

Every situation is different. The right threshold depends on your personal circumstances, other income, pension contributions and future plans for the business.

Decision factors

Things to weigh up

Tax efficiency

A limited company lets you draw a small salary (below the National Insurance threshold) and take the rest as dividends, which are taxed at a lower rate than income.

Limited liability

If the business runs into financial difficulty, your personal assets — your home, savings — are generally protected. As a sole trader they are not.

Admin and costs

Running a limited company means annual accounts filed at Companies House, a Corporation Tax return, and potentially payroll. These are manageable — but they do add cost and time.

Credibility

Some clients and larger businesses prefer to work with limited companies. It can open doors, particularly if you work in contracting or professional services.

Making Tax Digital

MTD for Income Tax affects sole traders and landlords. If you are already dealing with quarterly reporting, the additional compliance of a limited company may feel less daunting.

Future plans

Thinking about taking on employees, seeking investment or eventually selling the business? A limited company structure is usually easier to scale and transfer.
