What is a sole trader?

A sole trader is the simplest way to run a business in the UK. You register with HMRC, trade in your own name (or a business name) and report your income and expenses through a self assessment tax return each year. You and your business are legally the same entity. There is no separation between your personal and business finances in the eyes of the law.

Millions of people in the UK operate this way: tradespeople, consultants, childminders, market traders and many others. It is easy to set up, cheap to run and carries minimal ongoing paperwork, until your profits start to grow.

What is a limited company?

A limited company is a separate legal entity registered at Companies House. It has its own name, its own bank account, its own tax obligations and its own legal rights. You can be the sole director and sole shareholder of your company, but the company is distinct from you as an individual.

This structure is more involved to run, but it opens up tax planning options and gives you limited liability protection. Most directors pay themselves through a combination of salary and dividends, which changes how their income is taxed compared to a sole trader.

Tax: how each structure is taxed

How sole traders are taxed

As a sole trader, your profits are added to any other income you have and taxed under Income Tax rates. For 2026/27, the rates are:

• 0% on the first £12,570 (Personal Allowance)
• 20% on profits between £12,570 and £50,270 (Basic Rate)
• 40% on profits between £50,270 and £125,140 (Higher Rate)
• 45% on profits above £125,140 (Additional Rate)

On top of Income Tax, sole traders pay Class 4 National Insurance Contributions on their profits. Class 4 is charged at 6% on profits in the basic rate band and 2% above it. Class 2 National Insurance has not been compulsory since April 2024. Again, confirm current rates with HMRC or your accountant.

The important point is that sole traders pay tax on all business profits in the year they arise, whether or not they actually draw that money out. There is no flexibility to leave profits inside a business structure.

How limited companies are taxed

A limited company pays Corporation Tax on its profits. For 2026/27:

• 19% on profits up to £50,000 (Small Profits Rate)
• 25% on profits over £250,000 (Main Rate)
• Marginal relief applies on profits between £50,000 and £250,000

Once Corporation Tax has been paid, the remaining profits can be distributed to shareholders as dividends. In 2026/27, the first £500 of dividend income is tax-free (the Dividend Allowance). Above that, dividends are taxed at:

• 10.75% for basic rate taxpayers
• 35.75% for higher rate taxpayers
• 39.35% for additional rate taxpayers

Whether these combined rates (Corporation Tax plus Dividend Tax) work out lower than Income Tax and National Insurance as a sole trader depends on your circumstances. There is no single income level at which incorporation automatically becomes more tax efficient. The right structure depends on your profits, personal income requirements, other income, how much you plan to retain, pension contributions, extraction strategy and the additional costs and responsibilities of running a company. Your accountant can model this for your situation. You can read more about how we handle corporation tax for limited companies.

VAT: the same for both

VAT registration is not determined by your business structure. It is determined by your taxable turnover. In 2026/27, you must register for VAT once your taxable turnover exceeds £90,000 in a rolling 12-month period. We handle VAT returns for both structures.

Take-home pay: a practical comparison

At lower profit levels, for example £20,000 to £25,000, the tax difference between the two structures is modest and the extra administration of a limited company often outweighs the savings. The picture changes as profits grow.

A common limited company director strategy is to take a low salary (up to or around the National Insurance threshold) and draw the rest as dividends. In 2026/27, the Employer NI threshold is £5,000 and the Employer NI rate is 15%. A salary set just below the secondary threshold avoids Employer NIC on the company side, while keeping the director’s personal NIC liability low.

As an illustration: a director taking a salary of £12,570 and drawing further income as dividends may retain more post-tax income than a sole trader at the same profit level. The answer depends on your specific circumstances, including any other income you receive.

The key figures to feed into any comparison are:

• Your expected annual profit
• Whether you have other sources of income
• How much you need to draw from the business each month
• The additional accountancy costs a limited company involves

Good management accounts make this comparison far easier to run on a real-time basis.

Liability and risk

Sole trader liability

As a sole trader, you are personally liable for all business debts and legal claims. If your business runs into financial difficulty, your personal assets, such as your home, your savings and your car, are at risk. There is no legal separation between you and your business.

For many small businesses, this risk is manageable. If you operate with low overheads, no large contracts and no employees, the exposure is limited. But as your business grows, this changes.

Limited company liability

A limited company gives you limited liability. In most cases, your personal exposure is limited to the value of any shares you hold in the company and any personal guarantees you have signed. If the company cannot pay its debts, creditors generally cannot come after your personal assets.

There are exceptions. Directors can be held personally liable for fraudulent or wrongful trading. And banks often require personal guarantees for business loans, which removes much of the protection in practice. But as a general principle, the limited company structure provides a meaningful legal firewall between your personal finances and your business.

Admin and compliance

Sole trader obligations

Sole trader obligations are straightforward. You need to:

• Register with HMRC as self-employed
• File a self assessment tax return by 31 January
• Keep records of income and expenses
• Register for VAT if your turnover exceeds £90,000
• Register for payroll if you employ staff

Since 6 April 2026, if your self-employment or property income exceeds £50,000, you also need to comply with Making Tax Digital for Income Tax, which requires quarterly digital reporting to HMRC.

Limited company obligations

A limited company has significantly more compliance requirements. These include:

• Filing annual accounts at Companies House
• Filing a Corporation Tax return with HMRC
• Filing a Confirmation Statement at Companies House each year
• Running a payroll scheme if the director takes a salary
• Maintaining statutory company records
• Filing self assessment tax returns for directors personally
• VAT registration and returns if turnover exceeds £90,000

The additional admin means most limited company directors use an accountant. That cost, typically from around £1,000 to £2,500 or more per year depending on the firm and services, needs to factor into any tax saving calculation. Good bookkeeping throughout the year keeps accountancy costs down and year-end filing straightforward.

When to choose sole trader

Operating as a sole trader makes sense when:

• You are just starting out and profits are modest (under £25,000 to £30,000)
• You want minimal admin and low accountancy costs
• Your business involves low financial risk and no large liabilities
• You are testing a business idea before committing to a more formal structure
• You work in a sector where clients do not require a limited company (many smaller trades and service businesses fall into this category)

Many freelancers and sole traders in the early stages of their careers operate this way, and there is nothing wrong with that. The structure fits the business at that stage.

When to choose a limited company

Incorporating makes more sense when:

• Your profits are consistently high and the tax saving outweighs the extra admin cost
• You want limited liability protection as your business takes on contracts, employees or debt
• A client or contractor requires you to operate through a limited company (common in construction and professional services)
• You want to retain profits inside the company for future investment
• You plan to bring in business partners or investors, as shares are easier to issue and transfer than sole trader interests
• You want to separate personal and business finances more cleanly

Many healthcare professionals, content creators and e-commerce businesses find the limited company structure works well once they reach a sustainable level of income. That said, there is no universal threshold. The right answer depends on your numbers.

Making the switch from sole trader to limited company

If you start as a sole trader and later decide to incorporate, the process is manageable. You register a new limited company at Companies House, open a business bank account in the company’s name and inform HMRC of the change. Your existing sole trader registration is closed down.

There are some practical considerations:

• Any business assets transferred to the company may have Capital Gains Tax implications. Get advice before you transfer anything of significant value
• Existing contracts and client relationships are in your personal name, not the company’s. You will need to update these
• Your VAT registration can sometimes be transferred. Check with HMRC or your accountant
• Your accounting year-end will reset to the date of incorporation

The timing of incorporation matters. Switching mid-year can create complications with tax years and overlapping income. Most accountants recommend planning the switch to align with a natural accounting break.

Monitoring your cash flow during the transition period is important, as Corporation Tax payment deadlines differ from the self assessment payment on account system sole traders use.

The right structure is the one that fits your current income, your risk appetite and your plans for growth. Get proper advice before you decide, and revisit the question as your business evolves. The wrong structure costs you money. The right one frees you to focus on growing what you have built.

Frequently asked questions

At what profit level does a limited company become more tax-efficient than sole trader?

No fixed figure decides it. Your profit, how much you draw, your other income, pension plans and the extra running costs of a company all change the answer. A comparison from an accountant using your own figures will show which structure suits you.

Can I be both a sole trader and a limited company director at the same time?

Yes. You can run a sole trader business in one area and be a director of a limited company in another. Both incomes are reported through self assessment, and HMRC will tax your combined income accordingly. This is perfectly legal but can create complexity. Keep clear records for each.

Do I need an accountant if I operate as a sole trader?

You are not legally required to use an accountant as a sole trader, but many find it worthwhile. A good accountant will often save more in tax than they cost in fees, and they ensure your self assessment return is filed correctly and on time. As your income grows, professional advice becomes more important, not less.

What happens to my sole trader business name when I incorporate?

Your trading name does not automatically transfer to your limited company. You can register a company with the same name at Companies House (subject to availability and naming rules), but you should also consider trade mark protection if the name is important to your brand. Update all contracts, invoices and marketing materials to reflect the company name once incorporated.

Does incorporating protect me from all personal liability?

Not entirely. Limited liability covers most business debts and claims. Wrongful or fraudulent trading, any personal guarantee you sign and, in some cases, unpaid PAYE and NIC can still fall on you personally. The protection is real but not absolute.

How does Making Tax Digital affect sole traders?

Since 6 April 2026, sole traders and landlords with qualifying income above £50,000 must use Making Tax Digital for Income Tax. This means keeping digital records and submitting quarterly updates to HMRC through compatible software. The threshold drops to £30,000 from April 2027. Limited companies are not affected by MTD for Income Tax. If you are approaching these thresholds, plan ahead.
