Sole Trader or Limited Company in 2026/27: Which Is More Tax Efficient?

Should you operate as a sole trader or limited company in 2026/27?

It used to be fairly straightforward to answer this question. Once profits reached a certain level, running a limited company could often produce useful tax savings.

For 2026/27, the position is very different.

Higher dividend tax rates, Corporation Tax and employer's National Insurance mean that incorporating purely to save tax is no longer the obvious choice.

In fact, if you plan to withdraw all your profits each year, operating as a sole trader can now be more tax-efficient in many cases. However, tax is only one part of the decision.

Let's look at the numbers.

Sole trader or limited company: what's changed in 2026/27?

The biggest change for owner-managed companies is the increase in dividend tax.

From 6 April 2026, the dividend tax rates are:

At the same time, companies still face Corporation Tax of between 19% and 25%.

Employers also generally pay employer's National Insurance at 15% on salary above the £5,000 Secondary Threshold.

As a result, the tax advantage of taking a small salary and the remaining profits as dividends has reduced.

How is a sole trader taxed in 2026/27?

As a sole trader, you pay Income Tax and National Insurance on your taxable business profits.

For taxpayers in England, Wales and Northern Ireland, the standard Personal Allowance remains £12,570.

Income Tax is then generally charged at:

Your Personal Allowance also starts to reduce once your adjusted net income exceeds £100,000.

Sole trader National Insurance for 2026/27

Class 4 National Insurance is generally:

If your profits are high enough, Class 2 National Insurance is treated as paid rather than being an additional charge.

That makes the sole trader calculation relatively straightforward.

How is a limited company taxed in 2026/27?

A limited company has two potential tiers of tax.

First, the company pays Corporation Tax on its taxable profits.

The rates are:

After Corporation Tax, the company can distribute its remaining profits as dividends.

The shareholder may then pay dividend tax.

Therefore, money extracted from a company can effectively be taxed twice: once within the company and again when the shareholder receives the dividend.

What about paying yourself a salary?

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

A salary is normally deductible when calculating the company's taxable profits, provided the usual conditions are met.

However, employer's National Insurance also needs to be considered.

For 2026/27, the employer's National Insurance rate is 15%, with a general Secondary Threshold of £5,000.

The Employment Allowance can reduce an eligible employer's National Insurance bill by up to £10,500.

However, a company with only one director cannot normally claim the Employment Allowance if that director is its only employee liable for employer's National Insurance.

This distinction can make a significant difference to the calculation.

Sole trader vs limited company tax calculation for 2026/27

So, which structure actually pays less tax?

Let's use a simple example.

We will assume:

Here is a comparison taking into account the points mentioned above.

Whilst this is only a guideline, nevertheless, they demonstrate an important point:

A limited company is no longer automatically more tax-efficient than operating as a sole trader.

Example: £50,000 profit as a sole trader

Suppose your sole trader profit is £50,000.

You have a £12,570 Personal Allowance, leaving:

£50,000 - £12,570 = £37,430 taxable income

Income Tax at 20% is approximately:
£37,430 × 20% = £7,486

Class 4 National Insurance is approximately:
£37,430 × 6% = £2,246

Total Income Tax and Class 4 National Insurance are therefore approximately:
£7,486 + £2,246 = £9,732

That leaves approximately:
£50,000 - £9,732 = £40,268

What if the company can claim Employment Allowance?

The comparison changes if your company qualifies for the Employment Allowance.

For example, a company with other employees may be able to offset the employer's National Insurance arising on the director's salary.

Using the same broad assumptions, this improves the limited company result.

However, it does not necessarily make the company more tax-efficient than a sole trader.

That is why your circumstances matter more than ever in 2026/27.

When can a limited company still save tax?

The previous examples assume you withdraw virtually all the company's available profits.

But you don't have to do that.

A limited company can become much more attractive if you retain some profits inside the company.

For example, imagine your business makes £100,000 but you only need £50,000 personally.

A sole trader is generally taxed on the full £100,000 business profit, regardless of how much cash they withdraw.

A company is different.

You can take the amount you need and retain the remaining post-tax profits within the company.

You do not generally pay personal dividend tax on profits simply because the company has earned them. Dividend tax normally arises when a dividend is actually paid to you.

This ability to control when profits are extracted remains one of the biggest tax-planning advantages of a limited company.

Advantages of being a sole trader

Tax is not the only consideration.

For many small businesses, remaining a sole trader has significant advantages.

Less administration

Running a sole trade is generally simpler.

You don't have the additional Companies House and company-law obligations that come with running a limited company.

Lower accountancy costs

Simpler accounts and tax reporting can mean lower professional fees.

Of course, this depends on the complexity of your business.

Easy access to your money

The business's money is your money.

You don't need to decide whether a payment should be salary, dividend or a director's loan.

Losses can be valuable

Depending on your circumstances, sole trader losses may be available for relief against other income.

This can be particularly valuable during the early years of a business.

You can incorporate later

Starting as a sole trader doesn't mean you have to stay that way.

A growing business can incorporate later when the commercial or tax advantages justify it.

Careful planning is important when transferring an existing business to a company.

Advantages of a limited company

Despite the changing tax position, there are still many good reasons to trade through a company.

You can retain profits

This is one of the main advantages.

If you don't need all your business profits personally, you can leave money in the company for future investment.

That can defer your personal tax liabilities.

Pension planning can be attractive

A company may be able to make employer pension contributions for a director.

Subject to the relevant rules, these can be a very tax-efficient way of extracting value from a company.

Limited liability

A company is a separate legal entity.

Limited liability can therefore provide valuable commercial protection, although directors can still have personal liability in certain circumstances.

It may be easier to raise outside investment

Outside investors will normally want shares in a company rather than an interest in a sole trade.

This can be particularly relevant to tech, SaaS, AI and other high-growth businesses.

Tax-advantaged investment schemes such as SEIS and EIS also require a qualifying company structure.

You have more control over when you extract income

A sole trader is taxed on profits as they arise.

A company owner can often choose when to pay dividends, provided sufficient distributable reserves are available.

That can create useful planning opportunities.

A company may appear more established

Some customers, suppliers and investors prefer dealing with a limited company.

This isn't a tax saving, but it can still be commercially important.

What about sharing dividends with your spouse?

A limited company can sometimes present additional family tax-planning opportunities.

For example, spouses or civil partners may each own shares and receive dividends.
Therefore, if one spouse has unused basic-rate bands, this could reduce the family's overall tax bill.

However, you cannot simply transfer shares to somebody because they pay less tax. The share rights, settlements legislation, company law and wider tax consequences need to be considered.

Can pension contributions make a limited company more attractive?

Potentially, yes.

Company pension contributions can be one of the most valuable benefits of operating via a limited company.

Instead of taking all available profits as dividends, the company could make an employer pension contribution.

A qualifying contribution may reduce the company's taxable profit while avoiding an immediate dividend tax charge for the director.

However, pension annual allowance rules and other restrictions can apply.

What if you want to sell the business?

Your exit plans should also influence the choice between a sole trader and limited company.

Selling shares in a company can produce a very different tax result from selling the underlying business assets.

Business Asset Disposal Relief may also be relevant where the qualifying conditions are satisfied.
From 6 April 2026, the Business Asset Disposal Relief rate is 18%.

Therefore, it is worth considering your eventual exit before choosing or changing your business structure.

Is a limited company better for a growing business?

Frequently, yes - but not necessarily because of immediate tax savings.

A limited company can make sense if you plan to:

For a freelancer or consultant who withdraws nearly all their profits every year, the answer may be very different.

When should a sole trader become a limited company?

There is no single profit level at which everybody should incorporate.

You might see articles claiming you should form a company once profits reach £30,000, £40,000 or £50,000. However, that is too simplistic for the 2026/27 tax year.

The right time to incorporate will depend on a number of factors including:

The correct comparison should therefore be based on your numbers rather than a generic incorporation threshold.

Sole trader or limited company for 2026/27: which is best?

For the 2026/27 tax year, the answer has become more interesting.

If you make a modest profit and need to withdraw virtually all of it to live on, operating as a sole trader may be simpler and can also be more tax-efficient.

If you make more than you need personally, a limited company can still be extremely useful.

The ability to retain profits, control dividend payments, make employer pension contributions and bring in investors can outweigh the additional administration.

So don't incorporate simply because someone tells you that “limited companies pay less tax.” For many businesses in 2026/27, that statement is no longer true.

Instead, compare both structures using your expected profits and, crucially, how much of those profits you actually need to withdraw.

Frequently asked questions

Is it more tax-efficient to be a sole trader or limited company in 2026/27?

It depends on your circumstances. If you withdraw all the profits, a sole trader can now be more tax-efficient at a number of common profit levels. A limited company can become more attractive where profits are retained or other tax-planning opportunities are available.

At what profit should I become a limited company?

There is no set profit threshold. The amount you withdraw, your other income, pension planning and future plans can be just as important as the level of business profit.

Do limited companies pay less tax than sole traders?

Not necessarily. A company pays Corporation Tax and its shareholders can then pay tax when profits are extracted as dividends. You need to consider the combined company and personal tax cost.

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

Yes. Many businesses start as sole traders and incorporate once there is a commercial or tax reason to do so. However, the transfer should be structured correctly.

Can I revert from a limited company to a sole trader?

Yes, but closing or unravelling a business from a company can present tax issues. 

Is a limited company worth it if I retain profits in the business?

Potentially. Retaining profits is one of the situations where a company can be particularly useful because personal dividend tax can normally be deferred until profits are distributed.

Confirm the numbers before you make a decision

Choosing between a sole trader or limited company in 2026/27 isn't just about the headline tax rates.

It is about what you earn, what monies you need to extract from your business and what you want the business to become.
