The most reliable way to find a qualified tax advisor as a sole trader is to search the official online directories of recognised professional bodies—such as the AAT (Association of Accounting Technicians)—and verify that the advisor is registered as an official tax agent with HMRC. This guarantees you are hiring someone with proven training who is legally authorised to handle your taxes on your behalf.

Running a business as a sole trader in the UK means you are juggling a lot of tasks at once. Handing your Self Assessment tax return over to a professional can save you time, stress, and money. However, because anyone in the UK can legally call themselves an “accountant” or “tax advisor” without any training, knowing exactly what to look for is vital.

Here is a simple guide on what you need to check and how to find the right person for your business.


1. Look for the Right Qualifications (Like the AAT)

Because the accounting industry isn’t strictly regulated by law, relying on qualifications is your best safety net. You want an advisor who belongs to a professional body, which means they have passed difficult exams, have proven experience, and must follow strict ethical rules.

For a sole trader, a great qualification to look out for is the AAT (Association of Accounting Technicians).

  • What it means: Advisors with AAT letters after their name are highly trained in practical, day-to-day accounting and tax tasks.
  • Why it helps: They are perfectly suited to handle sole trader accounts, bookkeeping, and Self Assessment tax returns without charging the premium fees that a large corporate accounting firm might charge.

Other excellent professional bodies to look out for include the ATT (Association of Taxation Technicians), ACCA, or ICAEW (Chartered Accountants).

2. Ensure They Are an HMRC Registered Tax Agent

Finding someone who is good at maths is only half the battle. You need an advisor who can actually submit your forms and speak to the taxman on your behalf.

To do this, the advisor must be set up as an HMRC Tax Agent.

  • What it means: HMRC has officially recognised them and given them a dedicated agent code.
  • Why it helps: An authorised agent can file your tax returns directly through their professional software. More importantly, if HMRC has a question about your tax bill, your agent can speak to them directly. This saves you from having to wait on hold with HMRC yourself!

3. Step-by-Step: Where to Actually Find Them

Now that you know what you are looking for, here is how to track down a great advisor:

  • Search the Professional Directories: Go straight to the source. The AAT has a “Find an AAT Licensed Accountant” search tool on their website. You simply type in your postcode to find fully qualified professionals near you.
  • Ask Other Sole Traders: Word of mouth is incredibly powerful. Ask other local business owners, freelancers, or tradespeople who they use. If they have had a good experience with a qualified advisor, it’s a great starting point.
  • Check Local Reviews: Once you have a few names, look them up on Google or Trustpilot. Pay attention to reviews from other sole traders specifically.

4. Questions to Ask Before Hiring

When you find an advisor you like, give them a quick call or arrange a chat. Ask them these three simple questions before you sign any paperwork:

  1. “Are you a member of the AAT or another recognised professional body?” (Don’t be afraid to ask for proof!)
  2. “Are you registered as an agent with HMRC?” 3. “Do you have experience working with sole traders in my specific industry?”

By sticking to qualified professionals who hold HMRC agent status, you can get back to running your business with the peace of mind that your taxes are in safe, capable hands.
