Business account or personal account for a side hustle?

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

Sole traders aren’t legally required to have a separate business account, but many banks’ personal account terms don’t allow business use, and keeping money separate makes records and tax returns easier. Limited companies need a business account.

If your gross trading income is £1,000 or less in a tax year, the trading allowance means you may not need to tell HMRC (there are exceptions).

Trading allowance from GOV.UK, as of 4 October 2026. General information, not advice.

Who it’s for

  • Personal account: very small, occasional side income — if your bank’s terms allow it
  • Business account: regular side income, or anyone who wants clean records

Who should skip it

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

  • You trade through a limited company — you need a business account

Full explanation

If gross trading income goes over £1,000, you can claim the trading allowance instead of expenses, or deduct actual expenses — whichever suits you.

Free accounts such as Business Go from Zempler, or app-based accounts, can be a simple way to keep things separate.

The catch

Using a personal account against your bank’s terms can lead to it being closed. Many business accounts are free, so separating may cost nothing.
