Do sole traders need a business bank account?

Important: This guide provides general information, not personalised financial advice. Financial products, rates and eligibility rules can change, so check the provider’s current terms before applying. You can check a firm’s details on the FCA Register.

Quick answer

No — not legally. Business.gov.uk says sole traders and normal partnerships aren’t legally required to have a business bank account. But some personal accounts don’t allow business transactions, so check your bank’s terms before using one for your business.

Our pick if you decide to open one: a no-monthly-fee account such as Starling or Mettle, so the separation costs you nothing. If your business income is occasional and your bank allows it, a separate personal account can also work.

General guide only.

Who it’s for

  • New sole traders deciding whether to bother
  • Side-hustlers with small, occasional income
  • Sole traders currently using their personal account for business
  • Anyone preparing for Making Tax Digital

Who should skip it

These are general points to weigh up, not advice. You may want to look elsewhere if:

  • You run a limited company — Business.gov.uk says limited companies must have a business bank account
  • You’re in a partnership and your partners want shared access — check account options
  • You’re about to incorporate
  • You want tax advice — speak to an accountant

Full explanation

What the law says

As a sole trader, you and your business are the same legal person, so there’s no legal requirement to keep a separate business account (source: GOV.UK). You still need to keep records of income and expenses for Self Assessment.

When a business account is worth it

It’s worth considering if you have regular business income, need to invoice clients, want to set money aside for tax or will need to keep digital records under Making Tax Digital (qualifying income above £50,000 from April 2026; GOV.UK, checked 4 October 2026). A free account removes the cost argument.

When you might not bother

If your business income is small and occasional and your bank allows business use, a separate personal account may be enough. Revisit if your income grows.

The catch

Your personal account terms may forbid it. Business.gov.uk notes that some personal accounts don’t allow business transactions.

Mixed spending makes records harder. HMRC expects you to keep records of business income and expenses; untangling them from personal spending takes time.

Protection is shared either way. As a sole trader, your personal and business money at the same bank share one FSCS limit of £120,000.

FAQs

Is it illegal for a sole trader to use a personal bank account?

No. Business.gov.uk says sole traders aren’t legally required to have a business account. But your bank’s terms may not allow business use.

Do limited companies need a business account?

Yes. Business.gov.uk says limited companies must have a business bank account.

Will HMRC mind if I use a personal account?

HMRC needs accurate records. Mixed spending makes those harder to produce, but isn’t itself against the rules.

Is a business account more expensive?

Not necessarily. Several business accounts have no monthly fee, such as Starling and Mettle.

Does a business account help my credit?

Business.gov.uk says it can help build a credit rating for your business, which may help with loans or cards later.
