Do I Need a Business Bank Account?

If you’ve just started or are planning to start your business, one of your first admin questions will likely be: do I need a separate business bank account?

There’s no one-size-fits-all answer to this question. It depends on your business structure, your goals, and how you want to manage your money. But in most cases, separating business and personal finances is not only a smart move because it helps reduce hassle, but it also boosts credibility and helps you stay compliant.

Let’s take a closer look at when a business bank account is required, what the pros and cons are, and what to consider when choosing the right provider. As always, for anything complex or specific to your situation, it's worth speaking to a qualified tax advisor.

What is a business bank account?

A business bank account works in a similar way to a personal one - you can send and receive payments, set up direct debits, manage cash flow, and keep track of what’s going in and out. But crucially, it’s set up in the name of your business rather than your personal name.

This makes it easier to keep your personal spending separate from your business finances - especially useful at tax time. It also gives you a clearer overview of how your business is performing - something that’s easy to get wrong when you’re just getting started.

Legal requirements for business bank accounts

Different company setups come with different legal requirements - and some mean you have to have a business bank account.

Are limited companies legally required to have a business bank account?

Yes, if you’re running a limited company you’re legally required to have a business bank account. A limited company is a separate legal entity, which means you can't mix personal and business finances - hence the requirement for a business bank account. Payments must be made to and from the company via its bank account, not to and from you via your personal bank account.

Are sole traders legally required to have a business bank account?

No, sole traders have no legal requirement for a business bank account. So you can use a personal current account for business income and expenses. Many personal current accounts prohibit this in their terms, however, so while it might be technically allowed by HMRC, your bank may not be so accommodating.

What about partnerships and LLPs?

If you’re running a general partnership, you aren’t legally required to set up a business bank account. However, for the reasons we cover below, it’s arguably even more important for partnerships to manage their business finances separately from their personal finances. A business bank account gives partners clarity on the business’s financial position, lets them track income and outgoings, and can be critical to avoiding disputes.

Limited Liability Partnerships (LLP) are more like a limited company in that they have to maintain a separate bank account.

Why separate accounts are usually a better idea

Even if you're not legally required to have one, using a business bank account brings practical advantages - especially once your business gains momentum and you have more payments in and out to manage.

Here are some of the key reasons business owners decide to open a business account:

• Cleaner financial records - Keeping your accounts separate can ensure you always have a clear overview of your business’s financial position whenever you need it.
• Easier tax returns - With a business account, all your business transactions are in one place. That makes it quicker to prep your Self Assessment tax or pass records to your accountant. Having to sift through all of your personal and business expenses in one account can make things very complicated, and can take your precious time and focus away from the day-to-day running of your business.
• More professional - Invoices and payments coming from a named business bank account look more credible, especially for businesses that have more established clients.
• Access to business tools - Many small business bank accounts link directly to accounting software like Xero and QuickBooks. Digital banks also provide extra features built for businesses, like digital receipt capture, pots, Making Tax Digital compatibility and cash flow insights.
• Better funding options - If you’re planning to apply for a business loan, line of credit or trade account, most lenders will expect you to have a proper business account.

Are there risks to using a personal current account for business?

There can be, especially if you’re a sole trader using a personal current account in ways your bank doesn’t allow.

Some banks include clauses in their personal current account terms stating that the account is for personal use only. Using it to send or receive business payments could breach those terms. In some cases, that might lead to the account being frozen or closed.

It’s also much easier to make accounting errors when your personal and business expenses are mixed, which could cause issues when filing taxes or dealing with HMRC queries later on.

How to choose the right business bank account

There are dozens of providers offering business bank accounts to small businesses, from high street banks to digital-first challengers. Some offer basic functionality, while others throw in premium features, extra tools or access to credit.

Here are a few things to look out for:

• Ease of setup - Can you open the account online? How long does it take? What documents are required?
• Pricing transparency - Are there monthly fees? What about transaction limits or charges for ATM use?
• Integration with accounting tools - Does it work with your chosen bookkeeping software?
• Customer support - Is help available when you need it? Is it UK based?
• Cash or cheque handling - Some digital banks don’t support this, which may matter depending on how you operate.
