13/09/2022Finance , Sole Trader
Yes, a sole trader can run multiple businesses at the same time. About 3.1 million sole traders do it in the UK, but 20% of sole traders fail within their first year, and 60% don’t make it past five years, according to the Institute for Fiscal Studies, whose findings were based on HMRC tax records reported by BBC News.
While it’s completely legal, running multiple businesses as a sole trader comes with responsibilities. For success, you’ll need to know how taxes work, what (and if) you need to register, how to stay on top of admin, accurate record keeping and whether there comes a point where a different business structure (like a limited company) might make more sense.
Let CruseBurke expert accountants simplify the process and help you make the best decision for your business.
What Is a Sole Trader?
A sole trader is a self-employed person and runs one or more businesses on their own. There’s no legal difference between the person and the business. You keep the profits, but you are also personally responsible for debts and obligations. If something goes wrong, your personal assets may be at risk.
As a sole trader, you’ll need to register with HM Revenue & Customs (HMRC) for Self Assessment (HMRC’s system for collecting Income Tax from self-employed individuals) once your self-employed income goes over £1,000 in a tax year.
Is It Legal to have more than one Business as a Sole Trader?
Yes, it is legal. You can run more than one business at a time as a sole trader. HMRC recognises that many people do this. The businesses may be different kinds (say baking cakes in one, doing graphic design in another), or related. You don’t need separate legal entities for each. But there are implications, especially around tax, VAT, and paperwork.
Do You Need to Register Each Business Separately?
No, you don’t have to register each business separately with HMRC if you are already a sole trader. You’ll have one Unique Tax Reference (UTR). All your businesses are under that UTR. You report them separately in the same Self Assessment tax return, each business having its own “trade” section.
How to Register a Second Business as a Sole Trader
You don’t really “register” a second sole trader business as such. If you are already working as a sole trader, you inform HMRC of what you’re doing when you submit your Self Assessment. If the new trade is very different, you keep records separately. You may need to update your business name or trading style, but you will still use the same UTR.
How Tax and NI Work for Multiple Sole Trader Businesses?
Suppose you run more than one business as a sole trader. In that case, all profits from all businesses are added together for Income Tax and National Insurance. You fill in one Self Assessment tax return and declare each business’s income & expenses separately, but the total taxable profit determines your tax band. You don’t pay separately for each business.
You may also pay National Insurance Contributions (NICs). Since April 2024, Class 2 NICs are no longer compulsory, but you can choose to pay them voluntarily to protect your entitlement to certain benefits like the State Pension. Class 4 is based on profit levels. Rates change over time.
How Much Tax Do You Pay Running Your Own Business?
For 2024/25:
First £12,570 of profit is tax‑free (Personal Allowance). You only get one Personal Allowance. That’s the income you can make without paying Income Tax. Profits above that are taxed.
- Any profits between £12,571 and £50,270 are taxed at the 20% basic rate.
- Between £50,271 and £125,140 taxed at 40%.
- Above £125,140 taxed at 45%.
Class 2 NICs are no longer compulsory from the 2024/25 tax year. If your profits are above the Small Profits Threshold (£6,725), you will automatically receive a qualifying year for State Pension purposes. If your profits are below this threshold, you can choose to pay Class 2 NICs voluntarily to build entitlement to the State Pension and certain other benefits. Class 4 NICs based on your profit levels. For the tax year 25/26, — 6% on profits between £12,570 and £50,270, and 2% on profits over £50,270.
How Does Tax Work If You are Employed and Self‑Employed?
If you have both employment income (PAYE) and self‑employed income, both are added together to calculate your total income. You get the same Personal Allowance to use across your total income. You pay tax on your combined income (profit). HMRC will deduct some of your income via PAYE for your employment. Then your self-employed profits are added and taxed via Self Assessment. NICs are separate: employee NICs for your PAYE job; self‑employed contributions (Class 2(voluntary) and 4) on profits.
VAT for Sole Traders with Multiple Businesses
VAT rules mean you must look at the total turnover of all your businesses combined (for VAT purposes). If that total goes over the VAT registration threshold, you must register. As of April 2024, that threshold was raised from £85,000 to £90,000.
Even if one business is small and another is large, they together can push you over the limit. If that happens, you must register, charge VAT, and file VAT returns.
Can I have Two Businesses to Avoid VAT?
No, you cannot legally run two businesses as a sole trader to avoid VAT registration if their combined taxable turnover exceeds the VAT threshold, which is £90,000 (as of 2024/25 in the UK).
HMRC treats all your sole trader income as one when it comes to VAT. So if you operate two different sole trader businesses under your name, their sales must be added together. Suppose the total turnover for VAT‑eligible goods or services goes over the threshold in any rolling 12‑month period. In that case, you must register for VAT, even if no single business crosses it on its own.
What if I Split the Businesses Under Different Names?
Trying to artificially split one business into two or more to stay under the VAT threshold is known as “business splitting”, and HMRC watches out for it. If they believe the split is done only to avoid VAT, they can treat the businesses as a single entity and require VAT registration.
This could also trigger penalties and backdated VAT liabilities.
What to do instead?
If VAT registration is a concern, consider:
- Reviewing your pricing strategy to absorb VAT impact
- Exploring Flat Rate VAT Scheme (if eligible)
- Consulting an accountant to help with legitimate tax planning
Can One Business Be VAT-Registered and the Other Not?
No, under sole trader status, the VAT registration applies to you, the individual, not each business. So if you reach the threshold, you must register, and then all your taxable business activities are under that registration.
The Trading Allowance of Multiple Businesses
There is a trading allowance of £1,000 per tax year. If your total income from self-employment (across all businesses) is under that, you might not need to pay Income Tax on that income, or even register for Self Assessment in some cases. But once you’re over, you’ll need to declare everything. If your income exceeds £1,000, you must register for Self Assessment and declare the full amount. At that point, you can choose to either:
Deduct the £1,000 trading allowance from your gross income (instead of claiming actual business expenses), or
Deduct your actual allowable business expenses (if they’re more than £1,000).
Running Two Businesses Under One Name: Is It Allowed?
You can operate under one trading name or have different trading names for different ventures. What matters is that HMRC knows what you’re doing in your Self Assessment. As long as your trading name isn’t misleading or breaking business name rules, it’s OK.
What are the Disadvantages of being a Sole Trader?
Here are some of the downsides to running multiple sole trader businesses:
- Easy to mix up personal and business expenses.
- Unlimited personal liability: If something goes wrong in any business, you are personally responsible. Your car, your savings, your home could be at risk.
- One tax return for all profits: Profits from all businesses are added together. If combined profits are high, you could move into a higher tax band.
- More admin: More invoices, more expenses, more bookkeeping. It can get messy.
- Time, money, energy. Running two businesses doubles the number of tasks. Might burn you out.
- Growth limitations: If one business becomes large or risky, being a sole trader might not offer enough protection. Also, investors often prefer limited companies.
Keeping Separate Records of Multiple Businesses
Even though legally you’re one person with one UTR, it really helps to keep the books of each business separate. That means separate income, separate expenses, invoices, receipts, and bank entries. This makes Self Assessment easier. It also helps you identify which businesses are doing well and which might need fixing.
Accounting Software for Sole Traders
Good accounting software can do wonders. Look for ones that allow you to have multiple “trades” or business lines. Features to consider:
- Cloud accounting (e.g., Xero, QuickBooks, FreeAgent)
- Automatically separate profit/loss per business
- Track expenses (fuel, materials, equipment) per trade
- Easy invoice and Receipt scanning apps
- Digital record keeping (especially if VAT registered)
- Time tracking (if you charge for time)
- Planner/reminder apps for deadlines
- Many plumbers, designers, caterers, and other professionals use cloud-based tools.
It saves time, prevents errors, and helps you stay tax compliant.
Best Practices for Bookkeeping and Admin
Good bookkeeping helps you track your profits, manage cash flow, and stay prepared for tax time. Here are some simple tips:
- Use separate bank accounts (or at least clearly tagged transactions)
- Keep receipts, invoices, and bills for at least 5 years after the tax return date.
- Review your business finances on a monthly or quarterly basis.
- Use spreadsheets or software dashboards to compare performance.
What is the Difference Between a Sole Proprietorship and a Limited Company?
As a sole trader, you personally own everything, with unlimited liability, and are taxed as an individual (Income Tax + National Insurance), with simpler reporting requirements.
If we compare it to a limited company in the UK, the company is a separate legal entity. You might pay Corporation Tax ( tax that limited companies pay on their profits), then take profits via dividends or salary. Limited liability protects personal assets more.
Considering the benefits of a limited company helps you understand why some people opt to form a company when managing multiple or larger businesses.
When to Change from Sole Trader to Limited Company?
Stay sole trader if:
- You’re just starting out
- Profits are modest
- You want simpler admin and fewer legal requirements
- Risk is low
Consider forming a limited company (or multiple) if:
- Profits are increasing significantly
- Some businesses have higher liability or risk
- You want better tax planning options
- You aim to attract investment or scale
Can a Sole Trader Own More Than One Limited Company?
Yes, owning limited companies is different. Every limited company is legally distinct from its owners. They each have their own legal and tax responsibilities. You could have two limited companies alongside or instead of your sole trader ventures.
Pros of Setting Up Separate Limited Companies
Here are some of the benefits they offer compared to running everything as a sole trader:
- Limited liability protection: Your personal assets are better protected if things go wrong.
- Separation of finances, risk, and branding: Each company stands on its own
- Attractive to investors: Limited companies are more “official” and may inspire more confidence in investors.
- Greater tax planning flexibility: e.g., paying yourself via salary + dividends reduces corporate tax.
- Easier to sell or transfer ownership of one company without disturbing the others
- Clarity for clients and customers: You can have two different companies of cosmetics and baking items, the clients won’t be confused why a cosmetic shop is selling baking items.
Things to Consider Before Running Multiple Companies
Of course, there are trade‑offs:
- More admin: There might be more admin and compliance, each company must file accounts, pay Corporation Tax, etc.
- Additional fees: Costs are higher for accountants, filing fees, and possible audit. You can use the bookkeeping software without taking too much time.
- Tax Complexity: There might be complexity in tax. You’ll have to manage separate financials, possibly different tax years.
Professional Guidance
A sole trader can have multiple businesses. You report them under one UTR and one Self Assessment, with separate trade sections. All profits are added up for tax and NICs. You only get one Personal Allowance per year. VAT registration is based on the total turnover from all those businesses combined, the threshold is now £90,000 rolling 12 months. Good record-keeping and using appropriate tools can make life easier. Sometimes, switching to limited companies or having some of your businesses as limited companies can bring benefits.
Tax and business structures can get complicated. What works for one person might be bad for another. It’s wise to consult with an accountant or business advisor especially when profits rise, you are mixing business and personal finances, or thinking of changing structure. Small mistakes can cost money or cause penalties.
