Sole Trader vs Limited Company: The #1 Question We Get Asked

It is one of the most common questions we get asked:

“Should I stay as a sole trader, or should I set up a limited company?”

It sounds like it should have a simple answer. Sole trader or limited company. One or the other. Nice and easy.

But in reality, your business structure should fit you, your income, your plans, your appetite for admin, and the way you want your business to grow.

At Worthwhile Accountancy in Mundford, we work with sole traders, limited companies, CIS subcontractors, partnerships and growing local businesses every day. And the truth is, there is no one-size-fits-all answer.

For some people, staying as a sole trader is absolutely the right move. For others, moving to a limited company can offer better protection, more structure, and potential tax-planning opportunities.

The key is knowing when the conversation is worth having.

What does being a sole trader actually mean?

Being a sole trader is often the simplest way to start a business.

You work for yourself, you keep records of your income and expenses, and you report your profits through Self Assessment. GOV.UK says you must register for Self Assessment as a sole trader if you earn more than £1,000 in a tax year. (GOV.UK)

For many new businesses, side hustles, tradespeople and freelancers, this is a sensible starting point.

The advantages of being a sole trader

The biggest benefit is simplicity.

There is usually less admin than running a limited company, fewer statutory filing requirements, and the business is easy to understand. Money comes into the business, expenses go out, and the remaining profit is yours.

Being a sole trader can work well if:

• You are just starting out.
• You want to keep things simple.
• Your profits are still relatively modest.
• You do not need a more formal company structure yet.
• You are testing an idea before committing to something bigger.

It is also a familiar structure for many local trades, consultants, subcontractors and small business owners.

The downsides of being a sole trader

The main issue is that there is no legal separation between you and the business.

That means you are personally responsible for the business’s debts. If something goes wrong, your personal finances could be exposed.

There can also come a point where the tax position becomes less efficient, especially as profits grow. This does not mean that every successful sole trader should automatically become a limited company, but it does mean the numbers deserve a closer look.

And with Making Tax Digital for Income Tax now being introduced in phases, sole traders also need to think carefully about digital record-keeping. GOV.UK says MTD for Income Tax applies from 6 April 2026 for those with qualifying income over £50,000, then from 6 April 2027 for those over £30,000, and from 6 April 2028 for those over £20,000. (GOV.UK)

So while sole trader status is often simpler, it does not mean there is no admin at all.

What does trading through a limited company mean?

A limited company is a separate legal entity from you personally.

This means the company owns the business, receives the income, pays the bills, and is responsible for its debts. You usually become a director and may also be a shareholder.

This structure can make sense when a business becomes more established, more profitable, or more exposed to risk.

The advantages of a limited company

One of the biggest advantages is limited liability.

Because the company is legally separate from you, your personal assets are generally better protected, provided the company is run properly and you meet your duties as a director.

A limited company can also look more established and professional. For some clients, suppliers and larger contracts, having “Limited” after your business name can create more confidence.

There may also be tax-planning opportunities, particularly around how you take money from the company, whether through salary, dividends, pension contributions or leaving some profit inside the company for future investment.

But this has to be looked at properly. A limited company is not automatically better for everyone.

The downsides of a limited company

Limited companies come with more responsibility.

As a director, GOV.UK says you must keep company records, prepare annual accounts, complete and file a Company Tax Return, file accounts, and pay Corporation Tax. (GOV.UK)

There are also stricter rules around taking money out of the business. The money in the company is not simply “your money” in the same way it is when you are a sole trader.

You may also have higher accountancy fees because there is more work involved. That is not necessarily a bad thing if the structure saves tax, protects you, or supports growth — but it should be understood from the start.

So when should you think about switching?

There is no magic number.

However, for many businesses, once profits are consistently moving into the £50,000 to £60,000 region, it is usually worth having a proper conversation about whether a limited company structure could be more suitable.

That does not mean you definitely should incorporate at that point. It simply means the decision becomes more important.

At that stage, we would usually want to understand things like:

• How much profit the business is making.
• How much money you need personally each month.
• Whether you are reinvesting money back into the business.
• Whether you have employees, subcontractors or bigger contracts.
• Whether you want to protect your personal assets.
• Whether you want the business to feel more established.
• Whether you plan to grow, sell, take on a partner, or build a team.
• Whether the extra admin is worth the potential benefits.

This is why a quick answer is rarely the best answer.

The right structure depends on the person behind the business.

What if you are a CIS subcontractor or tradesperson?

This is a particularly important question for people working in construction.

Many CIS subcontractors start as sole traders. That can work well, especially in the early stages. But as your income grows, your costs increase, or you start taking on bigger jobs, it may be time to review the structure.

For example, you may need to think about:

• CIS deductions.
• Claimable expenses.
• VAT registration.
• Tools, van costs and materials.
• Whether you are using subcontractors.
• Whether you want to build a recognisable business name.
• Whether you are taking on more financial risk.

This is where tailored advice matters.

A limited company may be useful for some tradespeople, but it can also create extra admin if it is set up too early or without proper guidance.

At Worthwhile Accountancy, we help CIS workers and small construction businesses understand the numbers clearly before making that decision.

The Worthwhile way: we look at the person, not just the paperwork

This is the part we think matters most.

When someone asks whether they should be a sole trader or a limited company, they are not really asking a paperwork question.

They are asking:

“What is the best next step for me and my business?”

That is why we believe in having a proper conversation.

At Worthwhile Accountancy, we do not just look at the numbers in isolation. We look at your income, your goals, your responsibilities, your future plans and the way you want your business to work for you.

The team combines technical accountancy knowledge with a practical, down-to-earth approach. Whether you are speaking with Nicky, Sally, Michelle, Megan or Martyn, the aim is the same: to explain your options clearly, without jargon, so you can make a confident decision.

No scare tactics. No pushing you into a structure that does not suit you.

Just honest advice based on where you are now and where you want to go next.

His background makes him especially well placed to help clients understand the practical impact of decisions like whether to remain a sole trader or move to a limited company.

And outside the world of tax and figures, Martyn is a true enthusiast for staying active. You will often find him at a local parkrun or training for his next half-marathon. At home, he enjoys tackling DIY projects or heading out to explore the countryside with his dog.
