Do I Need a Business Bank Account as a Sole Trader?

If you’re self-employed or running a small business, you’ve probably asked yourself at some point: Do I actually need a business bank account? This is one of the most common questions we hear from sole traders, and the answer isn’t always crystal clear.

So, let’s clear it up. This post breaks down what’s legally required, what’s just helpful, and what could save you a lot of time, stress, and admin down the line.

The Short Answer

No, you’re not legally required to have a separate business bank account if you’re a sole trader.

As a sole trader, you and your business are legally the same entity. That means HMRC doesn’t expect you to use a business account, and you’re allowed to use your personal bank account to receive income and pay for business expenses.

But (and this is a big but) just because you can doesn’t always mean you should.

Why It's Still a Smart Move to Open a Business Bank Account

There are some very practical reasons to keep your business and personal finances separate. In fact, most experienced sole traders will tell you it’s one of the first things they wish they’d done from the start.

Here’s why:

Clearer records = Less stress

When your personal and business transactions are all mixed up, it’s a nightmare to track what’s what. Come tax time, you’ll be scrolling through pages of transactions trying to remember whether that £12.99 subscription was for work or Netflix.

Having a dedicated account for your business means everything that goes in or out is relevant. It keeps things neat and helps you avoid costly mistakes.

Simplifies your Self Assessment

If your business income and expenses are easy to identify, filling out your Self Assessment tax return is much quicker, and much easier to get right. It also makes it simpler to spot what you can claim as allowable expenses. What are allowable expenses? Find out here.

Makes working with an accountant easier

If you use an accountant or bookkeeper (or plan to in future), they’ll thank you for having a clean business account. It saves them time, and it could save you money in fees if they don’t have to wade through dozens of personal purchases to find your business transactions.

Looks more professional

When a client pays into an account with your business name on it, it looks more established and trustworthy. If you’re sending invoices or setting up payments, a proper business account sends the right message.

Puts you in the right mindset

This one’s a bit less obvious, but just as important: opening a business account helps you treat your business like a business. It’s a small mental shift that can make a big difference. You’re not just “doing a bit of work on the side”, you’re running something real. Having your own business account reinforces that mindset, which can build confidence, boost motivation and help you take things to the next level.

What the Banks Don’t Always Tell You

Even though it’s not illegal to use a personal account, your bank might not actually allow it!

Many personal banking terms and conditions include small print that says you can’t use your account for “business purposes.” If the bank spots regular business-related transactions, like incoming client payments or business purchases, they can freeze or even close your account.

That’s not a risk most people want to take, especially when your income depends on it.

What Actually Counts as Business Use?

This is where things can get a little blurry, especially if you’ve got a side hustle or you’re just starting out. So let’s break it down.

If you’re receiving payments for any of the following, you’re likely running a business in HMRC’s eyes:

• Freelance work or services

• Selling products (online or in-person)

• Coaching or consulting

• Side gigs, like photography, tutoring, baking, etc.

Even if it’s part-time or alongside a job, once you’re regularly earning income, it makes sense to treat it like a business.

On the expense side, things like software subscriptions, equipment, travel costs, and marketing tools also fall under business use, and are easier to track when they’re all in one place.

What to Look for in a Business Bank Account

If you’ve decided that keeping your finances separate is the way to go (good choice), here are a few things to look for in a business bank account:

• No monthly fees – Especially useful if you're just starting out

• Easy to open – Look for digital-first banks with quick online setup

• Good mobile app – So you can manage everything on the go

• Expense categorisation – Makes tracking costs a breeze

• Integration with bookkeeping tools – Helps automate your finances

At Strive, we often recommend Starling Bank to clients who are sole traders. They’re modern, easy to use, and offer a business account designed specifically for people in your shoes. You can check out the details on this page of our site if you’re curious.

It's Not Just About Compliance. It's About Making Life Easier

Let’s be honest: running your own business is hard enough without financial admin dragging you down. A business bank account isn’t about rules or red tape, it’s about giving yourself a bit of breathing room.

You’ll spend less time untangling your money, and more time doing the actual work you enjoy. You’ll know what’s coming in, what’s going out, and what you’ve got left to work with. That kind of clarity is powerful, and it’s the kind of thing that helps small businesses grow.

TL;DR

Do you need a business bank account as a sole trader? No, not legally. But if you want to stay organised, reduce stress, and make better financial decisions, it’s a solid move.

It doesn’t need to be complicated or expensive. And once you’ve got it set up, you’ll probably wonder how you ever managed without it.
