Mixing Personal and Business Money in One Bank Account: What Sole Traders Need to Do
Plenty of sole traders and landlords run everything through one current account: the shopping, the mortgage, the materials, the customer payments. That is allowed. What Making Tax Digital (MTD) for Income Tax asks is that your digital records hold your business income and expenses, and not the rest of your life. This guide covers how to get there from a mixed account without it taking over your evenings.
Do You Need a Separate Business Account?
Not for tax. As a sole trader, you and your business are the same legal person, so there is no rule that business money must sit in its own account. A limited company is different: its money belongs to the company and has to be kept apart.
Two things are still worth checking. Some banks' terms say a personal account is not for business use, so look at yours. And a separate account, even a free one, makes every job below faster, because the statement is already mostly business.
What Goes in Your Records, and What Does Not
Your digital records need each business transaction: the date, the amount and the category. Personal spending and personal income do not belong in them, even when they share a statement with your business.
Money you move out for yourself, often called drawings, is not a business expense. Neither is paying yourself. Your profit is worked out from your income and allowable expenses, and what you take out is simply your profit being spent.
A business cost you paid from your personal card still counts. Record it like any other expense, with the receipt, whichever account it came from.
Costs That Are Partly Business
A phone, a vehicle, broadband or part of your home can be used for both. For these you claim the business share only: if roughly 60% of your phone use is for work, 60% of the bill is the business expense. Keep a note of how you arrived at the figure, and use the same basis each time.
FileThat lets you set a business-use percentage on a record, so the full amount stays visible while only the business share is filed.
Before You Upload a Statement
• Go through the statement and pick out the business lines: customer payments, materials, fuel for work, software, insurance, professional fees.
• Mark the obviously personal ones as personal, so nobody has to think about them again.
• Flag anything partly business, so you can set its business share.
• Match business payments to receipts where you can, while you still remember what they were.
In FileThat, you upload the statement, check the suggested category on each line, and convert the business lines into digital records. Lines marked personal or left without a category are skipped, so they never reach your quarterly update.
Little and Often
Quarterly updates are due on 7 August, 7 November, 7 February and 7 May, and each covers the tax year so far. Sorting one month at a time is a ten-minute job; sorting a quarter the week it is due is not. See the 2026-27 deadlines calendar, and what HMRC means by digital records.
Frequently Asked Questions
Can a sole trader use a personal bank account for business?
Yes, as far as tax goes. A sole trader and their business are the same legal person, so HMRC does not require a separate account. Check your bank's terms, which sometimes forbid business use of a personal account.
Do I have to put personal transactions in my digital records?
No. Your digital records are for business income and expenses only. Personal spending and income stay out, even when they appear on the same bank statement as your business transactions.
Can I claim a business expense I paid with my personal card?
Yes. What makes it allowable is what it was for, not which account paid for it. Record it as a business expense with the receipt, the same as one paid from a business account.
Is money I take out of the business an expense?
No. Money you take out for yourself, often called drawings, is not a business expense. Your tax is worked out on your profit, which is your income less your allowable expenses, whatever you then take out.
