Can I Be a Sole Trader and a Limited Company in the UK? Tax, VAT, HMRC Registration and Director Duties Explained for 2026/27
Yes, you can operate as a sole trader while owning or directing a limited company in the UK. For 2026/27, the distinction remains: a sole trader is an individual running a business personally, while a limited company is a separate legal entity with its own reporting obligations.
Key Takeaways
- One person can run a sole trader business and own or direct a limited company. The company is legally separate from its owner; the sole trader business is not.
- HM Revenue & Customs (HMRC) can treat two businesses as one for VAT only where the separation is artificial, avoids VAT, and the parties are closely bound by financial, economic and organisational links.
- A company director must avoid conflicts of interest under section 175 of the Companies Act 2006.
Can I Run a Ltd Company and Be a Sole Trader?
A sole trader is an individual running a business personally, whether under their own name or a trading name. A limited company is legally separate from the people who own it. Nothing in the UK registration system stops the same person from doing both.
Some sources say flatly that a sole trader cannot be a limited company, and that statement is correct in a narrow sense. One business cannot be both at once. Incorporating means registering a limited company, a legal entity separate from its owners. It is not simply a change of name for the sole trader business.
A person who keeps the sole trader activity and also forms a second company has two businesses, each with its own accounts and tax return.
GOV.UK sets out sole trader and limited company structures as separate options. Sole traders register for Self Assessment with HMRC when required; limited companies register with Companies House and can set up Corporation Tax at the same time.
GOV.UK’s set-up-business guidance compares the two structures. Next comes the practical question of keeping them apart.
How Do You Keep the Two Businesses Separate?
Keep each business’s income, expenses and records identifiable. The company’s finances must be separate from those of its owners and directors because the company is a separate legal entity.
- Separate company banking. Keep the company’s banking separate from your personal and sole trader banking. A dedicated sole trader account is also useful for record-keeping, although sole traders are not generally legally required to have a business bank account.
- Separate books. Record income and expenses for each business in its own set of accounts.
- Separate invoices and contracts. Each document names the correct trading entity.
- No double-claiming expenses. An expense belongs to one business only. Where a cost is genuinely shared, such as a vehicle, apportion it on a recorded basis.
- Separate customer relationships. A customer should know which business it is dealing with.
Sole trader activity carries unlimited personal liability, so a debt in that business can reach personal assets. The company’s debts, in contrast, normally stay with the company. Registering each correctly is the next step.
How Do You Register as a Sole Trader and a Limited Company Director?
Use the following checklist to organise the registrations.
- Register the sole trader business with HMRC for Self Assessment. This is required if gross trading income exceeds £1,000 in a tax year.
- Incorporate the company at Companies House. The digital fee is £100 as of 1 February 2026.
- Verify your identity. Identity verification became mandatory for new directors and people with significant control from 18 November 2025.
- Set up Corporation Tax with HMRC. You can do this when registering the company with Companies House. If the company becomes active and is within the charge to Corporation Tax, tell HMRC within three months of the start of its tax accounting period.
- Keep separate records from day one. Arrange separate banking for the company, and consider a dedicated account for the sole trader business to simplify its records.
Registration is only the start; the two businesses are taxed very differently.
How Are the Two Businesses Taxed?
Sole trader profits are taxed as the individual’s income, subject to the applicable allowances and rules. A limited company pays Corporation Tax on its taxable profits; the owner’s personal tax treatment depends on how money is taken out.
A director is classed as an office holder for tax and National Insurance, as set out in GOV.UK’s employment status guidance for directors.
| Situation | Sole trader | Limited company |
|---|---|---|
| Tax on profits | Income Tax on taxable profits after applicable allowances; Class 4 National Insurance generally applies to profits above £12,570 in 2026/27 | Corporation Tax on company profit |
| Corporation Tax rates | Not applicable | 19% on profits up to £50,000 and 25% above £250,000, with marginal relief between |
| How you are paid | You take the profit | Salary or dividends; directors’ loans are another way to take money out, rather than earnings |
| Dividend tax (2026/27) | Not applicable | £500 allowance, then 10.75% basic, 35.75% higher, 39.35% additional rate |
| Personal Allowance | Standard allowance of £12,570 per individual, not per business; reduced where adjusted net income exceeds £100,000 | Standard allowance of £12,570 per individual, not per business; reduced where adjusted net income exceeds £100,000 |
| What you file | Self Assessment tax return | Company accounts, Corporation Tax return and a confirmation statement |
| Public record | Not on the public register | Company details held at Companies House |
Running both businesses does not give you a second Personal Allowance. The standard allowance is £12,570, but it falls by £1 for every £2 of adjusted net income above £100,000 and reaches zero at £125,140.
For 2026/27, Class 4 National Insurance is generally 6% on sole trader profits above £12,570 up to £50,270, and 2% above £50,270. Class 2 contributions are treated as paid where profits are at least £7,105; below that level, voluntary Class 2 contributions may be available.
Does the VAT Threshold Combine Both Businesses?
Not by default, but HMRC can combine them if the split is artificial. The VAT registration threshold is £90,000 of taxable turnover over any 12 months, and the deregistration threshold is £88,000.
Under HMRC’s Statement of Practice 4, HMRC may direct that two businesses be treated as one for VAT only where:
- the separation is artificial,
- it results in VAT being avoided,
- the parties are closely bound by financial, economic and organisational links, and
- the other legal requirements are met.
The individual sole trader and the limited company are normally assessed separately for VAT registration, even where the same person owns the company. HMRC can direct that artificially separated businesses be treated as one taxable person where the legal conditions are met.
Link indicators HMRC considers include common management, shared employees, shared premises or equipment, and shared customers. A genuine business reason for each business strengthens the case. Registration rules are on GOV.UK’s VAT registration page.
What Restrictions Apply When You Run Both?
Running both businesses can create conflicts between your interests as a sole trader and your duties as a company director. Competition or taking a company opportunity for yourself may engage the duty to avoid conflicts under section 175.
Director’s duties and conflicts of interest
Section 175 of the Companies Act 2006 requires a director to avoid situations in which their interests conflict, or could conflict, with the company’s interests. A sole trader business that competes with the company, or takes its customers, can breach that duty. The text is on legislation.gov.uk.
Disclosure alone does not necessarily resolve a conflict under section 175. Director authorisation must meet the statutory conditions, including the rules on the company’s constitution, quorum and voting by interested directors.
Can you invoice your own company?
Whether a director can bill their own company as a self-employed contractor is disputed among practitioners, and the question affects both tax and National Insurance.
HMRC’s former guidance on it, ESM4022, has been withdrawn, and HMRC now points to its employment status guidance and the Check Employment Status for Tax tool. Check in this order:
- Confirm whether the director is already an office holder of that company.
- Consider HMRC’s employment-status guidance and CEST tool when assessing the work. Using CEST is optional.
- Check whether IR35 could apply to any intermediary arrangement.
- Take written advice from an accountant before the first invoice.
A proposed contract with your company raises a separate director-duty question. Section 177 generally requires a director to declare the nature and extent of their interest to the other directors before the company enters the arrangement, unless an exception applies.
A sole trader may trade under their own name or a different one, but the name cannot include “limited”, “Ltd”, “LLP”, “plc” or similar company designations. The next question is when the whole arrangement is worth the effort.
When Does Running Both Make Sense?
Running both makes sense when the two activities are genuinely different or carry different levels of risk. The table sets out the typical situations.
| Situation | Sole trader | Limited company |
|---|---|---|
| Small side income, low risk | Usually suitable | Often more admin than it is worth |
| Higher-risk activity, such as contracts with large liabilities | Personal assets exposed | Limited liability protects personal assets |
| Wanting to keep profit in the business | All profit taxed personally | Profit can be retained after Corporation Tax |
| Two unrelated activities | Keep one in the sole trader business | Place the other in a company |
| Wanting minimal paperwork | Self Assessment only | Accounts, filings and director duties |
If separating activities reduces VAT liabilities, consider HMRC’s artificial-separation rules rather than assuming that separate registrations settle the position.
FAQ
Is it worth being a limited company as a sole trader?
It depends on profit, risk and how much you want to draw out personally. A company offers limited liability and potentially lower tax on retained profit, but adds accounts, filings and director duties.
Who pays more tax, a sole trader or a limited company?
Neither always pays more. A sole trader pays Income Tax on all profit, while a company pays 19% to 25% Corporation Tax and the owner then pays dividend tax on money drawn out. The balance shifts with profit level and how much is left in the company.
Can I be self-employed and a company director at the same time?
Yes. A director is an office holder, and the same person can also trade as a self-employed sole trader in a separate business. Each activity is reported separately.
Do I need separate bank accounts?
Keep the company’s banking separate from your personal and sole trader banking. A separate business bank account is not generally legally required for a sole trader, but it can make record-keeping simpler.
Do I have to tell HMRC about both businesses?
Yes, where registration or reporting is required. You must register for Self Assessment if your sole trader income exceeds £1,000 in a tax year. The company has separate Corporation Tax obligations, and you can set these up when registering it with Companies House.
Conclusion
A person can run a sole trader business while owning or directing a limited company. Keep the company’s finances separate, maintain clear records and check each activity’s reporting obligations. Pay particular attention to VAT registration, artificial separation and any conflict with your duties as a director.
