Sole traders do not pay Corporation Tax. Corporation tax is charged on the taxable profits of limited companies and certain other corporate bodies. As a sole trader, you pay Income Tax and National Insurance Contributions (NICs) on your profits through your annual Self-Assessment tax return.
A common point of confusion for new business owners is whether sole traders pay corporation tax or personal tax.
Let us break down everything you need to know about sole traders paying corporation tax for the 2026/27 UK tax year.

Why Sole Traders Do Not Pay Corporation Tax?
Many people wonder if sole traders pay corporation tax once their earnings start to grow. The reality comes down to how your business is set up. When you work as a sole trader, you and your business are legally the same person. Any profit your business makes belongs to you personally.
So when your business makes a profit, it’s treated as your personal income. This is the same as if you were paid a wage from a job.
Because of that, HMRC taxes those profits through the Income Tax system rather than Corporation Tax.
That’s the whole reason sole traders don’t pay corporation tax.
What Taxes Do Sole Traders Pay Instead?
So if you are wondering how sole traders pay corporation tax, the short answer is they simply don’t.
But if, as a sole trader, you do not pay corporation tax, then what taxes may apply to you as a sole trader?
Mainly two taxes apply:
- Income Tax on your profits, once you’ve gone over your Personal Allowance
- Class 4 National Insurance, which is basically NI for the self-employed
Some sole traders also pay Class 2 National Insurance. Though this was abolished for those with higher profits and remains voluntary only for those with low earnings (more on that below). And if you’re VAT-registered, that’s a separate thing entirely. And it has nothing to do with corporation tax either. Still remember, a sole trader cannot choose to pay Corporation Tax instead of Income Tax. The tax treatment depends entirely on the legal structure of the business.
Income Tax bands for sole traders in 2026/27
Here’s how it breaks down for the 2026/27 tax year, for England, Wales and Northern Ireland (Scotland has its own bands, so you need to check separately if that applies to you):
| Band | Taxable profit | Rate |
| Personal Allowance | Up to £12,570 | 0% |
| Basic rate | £12,571 to £50,270 | 20% |
| Higher rate | £50,271 to £125,140 | 40% |
| Additional rate | Over £125,140 | 45% |
So basically you do not pay tax on the first £12,570 of your profits. Then you pay:
- 20% on profits from £12,571 to £50,270,
- 40% from £50,271 to £125,140, and
- 45% on profits over £125,140.
Note: If your total income (not just self-employment profit, everything) goes over £100,000, your Personal Allowance starts shrinking. You lose £1 of it for every £2 you earn over that mark, and it disappears completely once you hit £125,140.
National Insurance for the self-employed
Alongside Income Tax, sole traders pay Class 4 NI on their profits:
| Profit | Class 4 NI rate |
| Up to £12,570 | 0% |
| £12,571 to £50,270 | 6% |
| Over £50,270 | 2% |
Class 2 contributions are no longer compulsory for most self-employed workers with profits above the Small Profits Threshold. These days it is only paid voluntarily by those with profits below the Small Profits Threshold, which is £3.65 a week for 2026/27. Voluntary Class 2 contributions are generally worthwhile if you want to protect your State Pension record if your profits are quite low.
How Tax Works for Sole Traders in the 2026/27 Tax Year
For the 2026/27 tax year, a typical sole trader’s tax mix looks like this:
| Sole trader tax in 2026/27 | What it is | Who pays it |
| Income Tax | Tax on your trading profits after expenses | Sole traders |
| National Insurance (Class 2 and Class 4) | Contributions based on profit levels | Sole traders |
| VAT (if above threshold) | Tax on sales, usually at 20 percent standard rate | Any business type when over threshold |
| Corporation Tax | Tax on company profits at 19–25 percent | Limited companies only |
The only line that does not apply to you as a sole trader is Corporation Tax. So no, sole traders pay corporation tax simply isn’t true, regardless of your profit level.
Why Do People Think Sole Traders Pay Corporation Tax?
It is easy to see where the confusion comes from. When you run a sole trader business, you might hire staff, send invoices, register for value added tax (VAT), and market your brand under a trade name. To your clients, you look and operate like any other business. This causes many new business owners to mistakenly assume sole traders pay corporation tax on their earnings.
But HMRC looks strictly at your legal structure:
- Sole Trader Structure: Unincorporated. Your business profits belong to you personally as soon as you earn them. You pay personal tax rates on those profits, whether you leave the money in your business bank account or spend it on personal items.
- Limited Company Structure: Incorporated at Companies House. The profits belong to the company, not you. The company pays corporation tax on those profits first. You only pay personal tax when you transfer money from the company account into your personal bank account.
Corporation Tax vs Income Tax
These two taxes get mixed up constantly, so it’s worth laying them side by side.
| Income Tax (sole traders) | Corporation Tax (limited companies) | |
| Who pays it | The individual, personally | The company, as its own legal entity |
| Rates 2026/27 | 0%, 20%, 40%, 45% depending on profit
(Different bands apply if based in Scotland) |
19% small profits rate up to £50,000, marginal relief applies between £50,000 and £250,000, with an effective marginal rate of 26.5% on profits within that band, and 25% main rate above £250,000 |
| When it’s paid | Once a year via Self Assessment, plus Payments on Account | Nine months and one day after the company’s year end |
| What happens next | Profit belongs to you once tax is paid | Withdrawing profit as dividends usually triggers a second tax charge |
| Filed with | HMRC | HMRC, alongside annual accounts filed at Companies House |
The big thing to remember is that Income Tax is charged on you, the person. Corporation Tax is charged on the company. A sole trader has no company sitting between them and their profits, so Income Tax is the only route that applies. It’s not that one is better than the other across the board; they’re just built for different structures.
This is really the crux of why sole traders pay corporation tax is a myth worth putting to bed early.
Sole Trader vs Limited Company: Where Corporation Tax Actually Comes In
This is usually where the confusion starts. People hear that limited companies pay a lower headline tax rate and assume switching over is an automatic win. It’s a bit more layered than that.
For 2026/27, corporation tax works like this:
| Company profit | Rate |
| Up to £50,000 | 19% (small profits rate) |
| £50,001 to £250,000 | Tapered rate via marginal relief, effectively up to 26.5% on profit in this band |
| Over £250,000 | 25% (main rate) |
So yes, 19% sounds a lot friendlier than 40% higher rate Income Tax. But here’s the bit a lot of blogs gloss over. Once a limited company pays corporation tax on its profit, and you then want to take that money out for yourself as a director, you’ll usually pay dividend tax on top when you draw it out.
So there’s a second layer of tax that sole traders simply don’t have. Sole traders pay once, through Income Tax and NI, and then the money is theirs.
That’s the clearest answer to whether sole traders pay corporation tax. They don’t, and there’s no second tax layer waiting for them either.
But that doesn’t mean sole trader is always cheaper, and it doesn’t mean limited company is always cheaper either.
It depends heavily on your profit level, how much you actually need to withdraw for personal use versus leave in the business, and your future plans.
This is genuinely one of those situations where running the actual numbers matters more than following a rule of thumb someone read online.
What Are The Advantages of Sole Trader Taxation?
There’s a reason so many people choose to trade as a sole trader. You never have to worry about how sole traders pay corporation tax. This is because the setup is far more straightforward than running a limited company:
- Simple to understand compared with company taxation.
- No separate company accounts or Companies House filing requirements
- You keep all your profit after tax; there’s no second layer like dividend tax
- Losses can often be set against other income in the same tax year, which can bring your overall tax bill down
- Simpler record keeping overall. However, you must use functional digital record-keeping software if your gross income triggers Making Tax Digital rules
- Cheaper to run from an accountancy and admin point of view, generally speaking
For many freelancers, contractors and small business owners, staying as a sole trader keeps administration manageable, especially during the early years of trading.
What Are The Disadvantages of Sole Trader Taxation?
Even though you don’t need to learn how sole traders pay corporation tax, the sole trader system still has a few drawbacks to keep in mind:
- Once profits push into the higher rate band, you’re paying 40% Income Tax plus 2% Class 4 NI, which adds up quickly
- Payments on Account can create cash flow surprises, especially in your second year of trading
- You carry unlimited personal liability, which is a legal point rather than a tax one, but it often factors into the same conversation
- Less flexibility to control the timing of your tax bill compared with a limited company, where you can choose when to draw dividends
None of this means a sole trader is the wrong choice. It just means the tax efficiency you get at lower profit levels can start working against you as your business grows.
If your business is growing quickly, it’s worth reviewing whether remaining a sole trader is still the best option.
When Does It Make Sense to Become a Limited Company?
There isn’t a single profit figure where every sole trader should incorporate.
Some people benefit from staying as a sole trader for years. Others save money by becoming a limited company much sooner. It depends on your profits, future plans, how you want to take money from the business and how much administration you’re happy to deal with.
A few signs it may be worth reviewing your business structure include:
- Your profits are increasing year after year.
- You’re leaving money in the business instead of spending it personally.
- You want to employ staff or bring in business partners.
- You’d like greater separation between your personal and business finances.
- Clients or suppliers prefer working with limited companies.
Changing structure isn’t something to rush into. It’s worth comparing the numbers first. An accountant can calculate how much tax you may pay under each option before you make the switch.
Making Tax Digital for Income Tax Self Assessment (MTD ITSA)
From April 2026, Making Tax Digital for Income Tax officially changes how many sole traders report their figures. Even though no sole traders pay corporation tax, nowqualifying gross income from self-employment and property over £50,000.
From April 2027, the threshold drops to £30,000, and it’s due to fall again to £20,000 from April 2028, pulling in a lot more sole traders over time.
Under these rules, you can no longer just send in one single tax return at the end of January. Instead, you must use HMRC-approved accounting software to keep digital records of every single business transaction.
You will then have to submit digital summary updates of your income and expenses to HMRC every quarter.
At the end of the tax year, you will also need to submit a final declaration to tie everything together.
It means a lot more regular admin for busy business owners.
The Bottom Line
So, do sole traders pay corporation tax in the UK? No. Sole traders do not pay Corporation Tax. Instead, they pay Income Tax on their business profits and may also pay National Insurance contributions, depending on their earnings.
Corporation tax exists specifically for companies. It means that the business is registered at Companies House as its own separate legal entity.
If you’re trading as a sole trader, you won’t need to register for Corporation Tax. Your tax is normally dealt with through Self Assessment.
