Setting Up a UK Company Is Easy. Running One Properly Is Not.

Starting a limited company is easy.

Deciding whether you actually need one is much harder.

For freelancers, consultants and small business owners, there is a persistent idea that at some point your turnover reaches a magic number and you should immediately become a limited company.

£30,000.

£50,000.

£100,000.

Pick whichever figure somebody mentioned on LinkedIn.

The reality is much less convenient.

There is no universal turnover level at which a limited company suddenly becomes the correct answer.

A UK limited company can be an excellent structure.

It can protect the business owner, make growth easier, allow profits to remain inside the business and create a company that exists separately from the person who founded it.

But it also creates:

• more administration;
• more filing obligations;
• additional accounting costs;
• stricter rules around taking money out;
• payroll and dividend decisions;
• Companies House responsibilities; and
• another layer of tax between earning profit and putting that money in your personal bank account.

So the right question is not:

"How much do I need to earn before I go Ltd?"

It is:

"What am I trying to build, what does the business earn, how much do I need personally, and what does incorporation actually improve?"

First: what is the difference between a sole trader and a limited company?

As a sole trader, you and the business are legally the same person.

You earn the business income.

You pay the business expenses.

The remaining taxable profit belongs to you and is generally subject to Income Tax and National Insurance.

There is no separate company sitting between you and the customer.

With a limited company, the position changes.

The company is a separate legal entity.

The company earns the income.

The company owns its money.

The company enters contracts.

The company pays Corporation Tax on its taxable profits.

You then need a proper mechanism for taking value out of the company personally.

That might include:

• salary;
• dividends;
• reimbursed expenses;
• pension contributions;
• repayment of money owed to you; or
• director's loan transactions.

That separation is one of the biggest advantages of incorporation.

It is also the source of much of the additional administration.

The first myth: there is a magic turnover figure

Turnover alone tells you surprisingly little.

Imagine two businesses.

Business A

A consultant invoices £90,000 per year.

Their business expenses are £10,000.

Profit before personal tax is around £80,000.

Business B

An online retailer has turnover of £200,000.

After stock, fulfilment, advertising, software and other costs, profit is only £25,000.

Which one should become limited?

You cannot answer that from turnover.

Business B is more than twice the size if you look only at revenue.

But Business A produces more than three times the profit.

The structure decision is therefore much more closely connected to:

• profit;
• risk;
• how much money you need personally;
• whether profits will be retained;
• how the business will grow; and
• what customers or investors require.

Turnover matters.

But it is not the decision.

Is a limited company still more tax efficient in 2026/27?

Sometimes.

But not automatically.

This is where a lot of outdated advice starts to fall apart.

For the 2026/27 tax year, a sole trader generally pays Income Tax on taxable profits and Class 4 National Insurance.

Class 4 National Insurance is currently:

• 6% on profits between £12,570 and £50,270; and
• 2% above £50,270.

A limited company operates differently.

The company may pay Corporation Tax at:

• 19% for qualifying profits up to £50,000;
• 25% for profits above £250,000; or
• an effective rate between those levels where Marginal Relief applies.

Those limits can also be reduced where associated companies exist.

But Corporation Tax is only the first layer.

If you then want the remaining profit personally, you need to extract it.

For many owner-directors that means some combination of salary and dividends.

Dividend tax rates for 2026/27 are:

• 10.75% at the ordinary rate;
• 35.75% at the upper rate; and
• 39.35% at the additional rate,

with a £500 Dividend Allowance.

Salary can create PAYE and National Insurance.

Employer National Insurance is generally 15% above the relevant £5,000 Secondary Threshold.

So the comparison is not:

20% Income Tax vs 19% Corporation Tax.

That comparison is far too simplistic.

The real comparison is closer to:

sole trader Income Tax + Class 4 NI

versus

Corporation Tax + salary taxes + employer NI + dividend tax + administration costs

depending on how the money is extracted.

This is why the answer needs to be modelled.

Retaining profit can change the calculation

This is where a limited company can become much more interesting.

Suppose your business makes £100,000 of profit.

But you only need £45,000 personally.

As a sole trader, the whole taxable business profit is generally yours for tax purposes even if you leave some of the cash sitting in the business bank account.

A limited company is different.

The company pays Corporation Tax on its profits, but money that remains inside the company does not necessarily need to be distributed personally immediately.

That retained cash might later be used for:

• hiring;
• equipment;
• marketing;
• software;
• working capital;
• acquiring another business;
• opening a new location;
• product development; or
• future investment in the business.

This can make incorporation more useful for someone who is building capital inside a business, rather than someone who needs to withdraw nearly everything they earn.

That distinction matters.

A freelancer making £80,000 and spending £75,000 personally may arrive at a very different answer from a business owner making £80,000 who only needs £35,000 personally.

Same profit.

Different structure decision.

When a limited company genuinely starts to make sense

Tax can be one reason.

But some of the strongest reasons to incorporate have very little to do with tax.

You want legal separation between yourself and the business

A limited company is legally separate from its owners.

As a sole trader, you are personally responsible for the debts of the business.

That is known as unlimited liability.

With a company limited by shares, shareholders' exposure to ordinary company debts is generally limited to their investment in the company.

That can become increasingly valuable where the business takes on:

• significant contracts;
• employees;
• premises;
• stock;
• borrowing;
• equipment;
• supplier credit; or
• greater commercial risk.

But limited liability is not absolute.

If you personally guarantee a company loan, lease or other debt, you can still become personally responsible for that obligation.

Directors can also become personally liable in certain circumstances involving misconduct, insolvency or breaches of their duties.

So incorporation provides protection.

It does not provide immunity.

Your clients expect a company

For some consultants and freelancers, the decision is commercial rather than tax-driven.

Large businesses may prefer or require suppliers to operate through incorporated entities.

Their procurement process may ask for:

• company registration details;
• company accounts;
• business insurance;
• VAT details;
• company banking;
• supplier onboarding documents; and
• formal contracts with a legal entity.

If the customers you want to work with expect an incorporated supplier, forming a company can remove a commercial barrier.

But there is an important warning for contractors.

Having a limited company does not automatically make you self-employed for tax purposes.

If you provide services through your own company but your actual working relationship looks like employment, the off-payroll working rules commonly known as IR35 can become relevant.

The rules look at the real engagement.

Not simply the fact that your invoice says Ltd at the top.

IR35 matters particularly for consultants and contractors

Imagine you form a company because one organisation offers you a 12-month consulting contract.

You work five days per week.

Only for them.

Using their systems.

Under their direction.

At hours they determine.

You cannot send somebody else to perform the work.

You need permission to take other clients.

Putting a limited company between yourself and that organisation does not automatically transform the relationship into a genuinely independent business.

The off-payroll rules are designed to address situations where someone provides services through an intermediary but would broadly have been treated as an employee if engaged directly.

For public-sector clients and medium or large private-sector clients, the client will generally have responsibility for assessing status under the off-payroll rules.

Where the private-sector client is small, responsibility can remain with the worker's intermediary.

So for consultants, the question should not simply be:

"Should I form a company?"

It should also be:

"Am I genuinely operating an independent business?"

You want to bring in another owner

A sole trader has one owner.

You.

If another person is going to own part of the business, the structure needs to evolve.

That could mean a partnership.

Or it could mean a company with multiple shareholders.

A company can provide a clearer framework for:

• ownership percentages;
• voting rights;
• different share classes;
• investment;
• dividends;
• succession;
• selling shares; and
• bringing in future investors.

If your plan is to build something bigger than one person's freelance income, this separation between the founder and the business becomes increasingly useful.

You want to build something that could eventually be sold

A sole trader can absolutely build a valuable business.

But a limited company can make ownership of the business clearer.

The company may own:

• contracts;
• customer relationships;
• intellectual property;
• websites;
• brands;
• equipment;
• employees;
• systems; and
• trading history.

Eventually, a buyer might acquire:

• the company's trade and assets; or
• the shares in the company itself.

That can make a limited company a natural structure for an entrepreneur whose long-term goal is not simply:

"I want to earn a good income."

but:

"I want to build an asset."

You want to retain money for growth

This is worth repeating because it is one of the strongest commercial arguments.

A limited company can accumulate post-tax profits.

That creates a pool of company capital that can potentially be reinvested.

A sole trader can of course leave money in a business bank account too.

But from a tax perspective, the sole trader is still generally taxed personally on the business profit.

The limited company creates a clearer distinction between:

profit earned by the company

and

money extracted by the individual.

For a growing business, that distinction can be useful.

You want clearer financial discipline

This one is underrated.

A sole trader can sometimes blur the line between:

business money

and

my money.

The same bank account gets used.

Personal spending gets mixed with business spending.

Tax money is accidentally spent.

Then January arrives.

A limited company forces stronger separation.

The company owns the cash.

Director withdrawals need to be classified.

Dividends need sufficient distributable profits.

Salary goes through payroll.

Expenses need to belong to the business.

Director's loans need monitoring.

That additional discipline can actually improve the way a growing business is managed.

But it only works if the director respects the separation.

When a limited company probably does not make sense

A company is not a badge of seriousness.

Sometimes staying as a sole trader is the better business decision.

You are testing whether the business works

Imagine you are employed full time and start doing occasional freelance design work.

You expect:

£5,000 this year.

Maybe £15,000 next year.

Maybe it becomes a business.

Maybe it doesn't.

Do you immediately need:

Companies House.

Corporation Tax.

Company accounts.

Payroll.

Dividend paperwork.

A business bank account.

A confirmation statement.

Potential director's loan accounting.

Probably not.

A sole-trader structure allows you to test the market with much less administration.

You can always incorporate later if the business grows.

Your profits are relatively modest

Low turnover does not automatically mean you should stay sole trader.

But if the business makes relatively modest profits and you need essentially all of them for personal living costs, the tax and commercial benefits of incorporation may not justify the additional cost and administration.

A company is not free to operate simply because incorporation is cheap.

There may be costs for:

• annual accounts;
• Corporation Tax returns;
• bookkeeping;
• payroll;
• confirmation statements;
• software;
• Companies House filings; and
• professional advice.

Those costs need to be part of the comparison.

Saving £700 in theoretical tax while spending £1,500 more administering the structure is not clever tax planning.

You need every pound the business makes

This is particularly important.

The ability to leave profits inside a company can be valuable.

But if you cannot leave profits inside the company because you need all the cash personally, that advantage largely disappears.

You may still choose a company for legal or commercial reasons.

But the tax case may be less compelling.

Ask yourself:

"After paying my personal bills, can I actually leave meaningful money inside the business?"

If the answer is no, incorporate for the other reasons.

Not because somebody told you retained profits were tax efficient.

Your business is simple and low risk

A freelance writer working from home with:

• no employees;
• no stock;
• no borrowing;
• no premises;
• low professional risk; and
• several small clients

has a very different risk profile from:

• a construction company;
• manufacturer;
• gym;
• retailer;
• employer;
• agency with staff; or
• business signing large customer contracts.

Limited liability can be valuable.

But its value depends partly on what could realistically go wrong.

Business insurance may also remain important regardless of structure.

You hate administration and do not want to pay someone else to manage it

This sounds trivial.

It isn't.

A company creates responsibilities.

The director must ensure that the company:

• keeps proper records;
• prepares annual accounts;
• files a Company Tax Return;
• pays Corporation Tax;
• keeps Companies House information current; and
• complies with company law.

You can appoint an accountant to manage much of the process.

But as director, you remain legally responsible.

If you want the simplest possible structure and the company offers little commercial advantage, simplicity itself has value.

Sole trader does not mean "no admin" anymore

There is also an important 2026 reality.

Sole trader status is simpler than running a company.

But for some businesses, it is no longer simply:

"Do the bookkeeping once a year and send a Self Assessment return."

Making Tax Digital for Income Tax is now being introduced.

From 6 April 2026, sole traders and landlords with qualifying income over £50,000 fall within MTD for Income Tax.

The threshold falls to:

• more than £30,000 from April 2027; and
• more than £20,000 from April 2028.

Affected taxpayers need compatible software, digital records and quarterly updates to HMRC.

So the administrative gap between sole trader and limited company has narrowed somewhat for higher-turnover sole traders.

But they are still different structures with different legal and tax consequences.

You should not incorporate simply to avoid MTD.

What if you are only making a small amount on the side?

For very small amounts of self-employed income, the £1,000 trading allowance may be relevant.

If your gross trading income is £1,000 or less, you may not need to tell HMRC about it, subject to the rules and exceptions.

Once gross trading income exceeds £1,000, registration for Self Assessment as a sole trader may be required.

Again, forming a company for £2,000 of experimental freelance income would usually be solving a problem that does not yet exist.

VAT does not decide whether you should incorporate

Another misconception:

"I've hit the VAT threshold, so I need to become limited."

No.

VAT registration and legal structure are separate questions.

A sole trader can be VAT registered.

A limited company can be VAT registered.

For a UK-established business, the compulsory VAT registration threshold is currently £90,000 of taxable turnover, subject to the detailed rules.

Changing from sole trader to limited company can itself create VAT considerations where an existing business is transferred, so it is better to plan the transition rather than assume a new company creates a clean slate.

Tax efficiency should be measured after every layer of tax

If someone tells you:

"A company only pays 19% tax."

ask them what happens to the money next.

If the company makes a profit, Corporation Tax may apply.

If you want the remaining money personally, another tax event can arise.

If you take salary:

PAYE and National Insurance can be relevant.

If you take dividends:

Dividend Tax can apply.

If you borrow company money:

Director's loan rules can apply.

If the company contributes to your pension:

Different rules apply again.

This does not mean companies are tax inefficient.

It means tax efficiency needs to be calculated across the whole journey of the money.

Business profit.

Corporation Tax.

Extraction.

Personal tax.

Cash left personally.

Cash left in the company.

That is the number that matters.

"Salary plus dividends" is not a universal formula

Many owner-managed companies use a combination of salary and dividends.

That can still be effective.

But the optimal structure depends on factors such as:

• company profit;
• other personal income;
• whether your Personal Allowance is available;
• Corporation Tax rate;
• employer National Insurance;
• Employment Allowance eligibility;
• dividend tax band;
• pension planning;
• student loans;
• distributable reserves; and
• how much cash you actually need personally.

In 2026/27, the dividend ordinary and upper rates have increased.

Employer National Insurance is also now generally charged at 15% above a £5,000 secondary threshold.

So copying somebody else's salary figure from an online article is not financial planning.

It is copying somebody else's assumptions.

What about expenses?

Another common reason people give for incorporating is:

"I'll be able to put more things through the company."

Be careful.

The company structure does not make personal expenditure magically tax deductible.

Business expenses still need to meet the relevant tax rules.

Some expenses are treated differently for companies and sole traders.

Benefits provided to directors and employees can also create separate tax consequences.

The correct structure should be chosen because it suits the business.

Not because you want to put dinner, a car and a holiday through a company.

What about borrowing and mortgages?

This is another area where structure can have indirect consequences.

If you plan to apply personally for:

• a mortgage;
• remortgage;
• significant personal borrowing; or
• another financial product,

the way you take income from the business may affect how a lender assesses affordability.

Some lenders are comfortable with owner-directors.

Some look primarily at salary and dividends.

Others may consider company profit or retained profit under particular underwriting criteria.

That is a lender decision, not an accounting rule.

So if a major mortgage application is planned, it can be sensible to understand the evidence the lender expects before changing your remuneration strategy.

Your accountant can help prepare financial information.

Regulated mortgage-product advice should come from an appropriately authorised adviser.

Should you incorporate because you are earning £50,000?

Not automatically.

At £50,000 profit, a company might make sense.

It might not.

The answer depends on questions such as:

• How much do you need to withdraw personally?
• Do you have other income?
• How risky is the business?
• Do clients prefer a company?
• Will you retain profits?
• Are you hiring?
• Do you want another shareholder?
• Are you building something to sell?
• Will IR35 be relevant?
• What will the additional accounting cost?
• What does the tax comparison actually show?

The number £50,000 by itself cannot answer any of those questions.

Should you incorporate because you are earning £100,000?

The case may be stronger.

But still not automatic.

At higher profits, tax planning becomes more important.

The Personal Allowance also begins to taper once adjusted net income exceeds £100,000, which can significantly increase the effective marginal tax rate for individuals.

But a company only helps if the company structure actually suits what you do with the money.

If every pound ultimately needs to be extracted personally, the calculation can be very different from a founder who can retain £50,000 per year inside the business.

Again:

profit matters.

Extraction matters.

Commercial plans matter.

A better test: ask these ten questions

Before incorporating, ask yourself:

1. How much profit does the business actually make?

Not turnover.

Profit.

2. How much of that profit do I need personally?

If nearly all of it needs to leave the business, say so.

3. Can I leave money inside the business for growth?

If yes, the company structure may become more useful.

4. What could realistically go wrong?

Think about contracts, customers, staff, debt, premises and professional risk.

5. Do my customers care about my structure?

Some do.

Some genuinely do not.

6. Am I building a job or a business?

There is nothing wrong with either answer.

But they are different objectives.

7. Will anybody else own part of the business?

If yes, ownership structure matters.

8. Could I eventually sell this business?

If that is the goal, build with that in mind.

9. Am I genuinely independent?

Consultants and contractors should consider employment-status and off-payroll rules.

10. Does the tax saving exceed the extra cost and complexity?

This is the calculation people often forget.

Can you start as a sole trader and incorporate later?

Absolutely.

In fact, for many small businesses that is the most sensible route.

Start simply.

Prove that customers exist.

Build revenue.

Understand your margins.

Build cash reserves.

Then incorporate when the commercial or financial case becomes clear.

But incorporation itself should be planned.

Moving an existing sole-trader business into a company can involve:

• transferring assets;
• customer contracts;
• equipment;
• stock;
• VAT;
• employees;
• business names;
• intellectual property;
• bank arrangements; and
• potentially tax consequences.

So "I'll just become Ltd tomorrow" can be unnecessarily messy once the business has grown.

The best time to review the structure is usually before it becomes urgent.

Can you go back from a limited company to sole trader?

Potentially.

But it is not simply a switch in accounting software.

The company is a separate legal entity.

If you stop trading through it, you need to decide what happens to:

• company assets;
• cash;
• debts;
• contracts;
• taxes;
• retained profits;
• employees; and
• the company itself.

The company may ultimately be made dormant, struck off or formally closed depending on the circumstances.

So incorporation should not be treated as a free trial.

Sole trader or Ltd: the practical comparison

Sole trader may make more sense when:

• you are testing a new business;
• profits are still modest;
• you need most of the profit personally;
• business risk is low;
• you have no employees;
• you have no outside investors;
• customers do not care about your legal structure;
• you value simplicity; and
• there is no clear tax or commercial benefit from incorporation.

A limited company may make more sense when:

• profits are consistently higher;
• you can retain meaningful cash in the business;
• commercial risk is increasing;
• you are signing larger contracts;
• clients expect incorporated suppliers;
• you plan to hire;
• you want another shareholder or investor;
• you want clearer separation between business and personal finances;
• you are building a business that could eventually be sold; or
• the full tax calculation shows a genuine benefit.

Notice something?

"My turnover reached £50,000" is not on either list.

The Solutio approach

I do not think every successful freelancer needs to become a limited company.

And I do not think staying as a sole trader means you are running a less serious business.

The structure should follow the business.

Not your ego.

Not somebody else's company.

Not a TikTok tax tip.

Not the belief that adding Ltd after your name automatically means you have become more successful.

At SolutioRemote, the decision starts with the numbers.

We look at:

• current profit;
• expected future profit;
• personal income requirements;
• other sources of income;
• tax position;
• business risk;
• retained cash;
• future hiring;
• customers;
• investment plans; and
• long-term goals.

Then we can model what the different structures actually mean.

Sometimes the answer is:

"Yes. It is time to incorporate."

Sometimes it is:

"Stay sole trader for another year."

Both can be good advice.

Because the objective is not to create more companies.

The objective is to help you build the right financial structure for the business you actually have.

Frequently asked questions

At what income should I become a limited company?

There is no universal income or turnover threshold at which you must become a limited company.

The decision depends on profit, how much money you need personally, risk, commercial requirements and the tax comparison.

Is £50,000 the point where I should go limited?

Not automatically.

A business earning £50,000 of profit where the owner needs all the cash personally can have a very different answer from a business earning the same amount that can retain significant profits for growth.

Is a limited company always more tax efficient?

No.

A limited company pays Corporation Tax and the owner may then face additional tax when extracting money through salary or dividends.

The total company and personal tax position needs to be compared with sole-trader Income Tax and National Insurance.

What tax does a sole trader pay in 2026/27?

A sole trader can pay Income Tax on taxable profits and Class 4 National Insurance.

For 2026/27, the standard Class 4 rate is 6% on profits between £12,570 and £50,270 and 2% above £50,270.

The overall position depends on the individual's circumstances and other income.

What Corporation Tax does a limited company pay?

For the financial year beginning 1 April 2026, the small profits rate is 19% for qualifying profits up to £50,000 and the main rate is 25% above £250,000.

Marginal Relief can apply between those amounts.

The thresholds can be reduced where associated companies exist.

What is the dividend tax rate in 2026/27?

For 2026/27, dividend rates above the relevant allowances are 10.75%, 35.75% and 39.35%, depending on the individual's tax band.

The Dividend Allowance is currently £500.

Does being a limited company protect me personally?

A limited company is legally separate from its owners and generally provides limited liability.

However, directors can still have personal exposure in circumstances such as personal guarantees, certain misconduct or breaches of directors' duties.

Appropriate business insurance may also still be required.

Can I stay sole trader if turnover exceeds £100,000?

Yes.

There is no general requirement to incorporate simply because turnover reaches £100,000.

Other obligations such as VAT, Making Tax Digital and tax payments may apply, but these do not automatically require you to form a company.

Do I need a limited company to register for VAT?

No.

Both sole traders and limited companies can be VAT registered.

Does having a limited company mean IR35 does not apply?

No.

The off-payroll working rules can apply where an individual supplies services through an intermediary but would broadly have been treated as an employee if engaged directly.

The actual contractual terms and working arrangements matter.

Can I start as a sole trader and become limited later?

Yes.

This is a common route.

But once the business has significant assets, VAT registration, employees or contracts, the transition should be planned rather than treated as a simple name change.

Still not sure whether you actually need a company?

That is usually a good sign.

It means the decision deserves a calculation rather than a guess.

SolutioRemote can compare the sole-trader and limited-company position based on your actual numbers and plans.

Not a generic turnover threshold.

Not somebody else's circumstances.

Yours.

Choose the structure because it improves the business.

Not because you think successful businesses are supposed to have Ltd after their name.
