Do I need an accountant for my small business? It’s one of the most common questions I hear, and the honest answer isn’t a straight yes or no. It depends on where you are, what you’re dealing with, and how much time and stress you’re willing to take on yourself.

What an accountant actually does for a small business

Most people think of an accountant as someone who files your tax return once a year. That’s part of it, but it’s probably the smallest part. A good accountant keeps your records in order, makes sure you’re claiming everything you’re entitled to, tells you what you owe before HMRC asks, and spots things you’d never notice yourself.

For sole traders and limited company directors, that can mean filing your Self Assessment, preparing your annual accounts, handling your VAT returns, running your payroll, and advising you on how to structure things in a way that’s tax-efficient. Done properly, it’s not just compliance. It’s someone in your corner all year, not just at January.

When does it actually make sense to get an accountant?

If you’re earning more than the personal allowance, have more than one income source, or you’ve recently gone self-employed, the case for an accountant gets pretty strong. The tax rules aren’t designed to be simple. Missing a deadline, getting a calculation wrong, or failing to register for VAT on time can all result in penalties from HMRC.

There’s also the time question. According to the Office for National Statistics, UK business creations rose 10% in Q4 2025. A lot of new business owners are spending evenings wrestling with spreadsheets when they could be doing actual work. An accountant frees that time up and usually saves more in tax than they charge.

What to look for when choosing an accountant

The first thing I’d say is: find someone who actually talks to you. A lot of people get passed around between junior staff and never speak to the same person twice. That’s frustrating when you need a quick answer about whether a purchase is deductible or what happens if you miss a filing deadline.

Check that they’re qualified. AAT, ACA and ACCA are the main recognised qualifications. Ask whether they work with businesses like yours, whether their fees are fixed, and how quickly they respond. If a firm can’t give you a straight answer on any of those things before you sign up, that tells you something.

What about just using accounting software yourself?

Software like QuickBooks, FreeAgent, Xero or Sage can genuinely help you keep your records tidy. I’d recommend using one. But software doesn’t tell you what you’re missing, it doesn’t advise you on tax planning, and it doesn’t know that you could be structuring your director salary differently to save money. It records what you put in.

A good accountant sets the software up for you, checks that it’s categorising things correctly, and uses the data to give you useful information. The two things work together. One without the other usually means either good records with no advice, or advice with no reliable records to base it on.
