    Questions to Ask Before Hiring a Tax Professional (and the Red Flags to Watch For)

    By Inder Grewal, IRS Enrolled Agent · Updated September 25, 2026 · 12 min read

    Most people hire a tax professional the same way they hire a plumber — find someone available, check the price seems reasonable, hope for the best. That works fine until something goes wrong, and with taxes, something going wrong can mean penalties, missed deductions, or an IRS problem that didn't have to happen. Asking the right questions upfront, and knowing the warning signs, takes fifteen minutes and can save you years of frustration.

    Questions to Ask Before You Hire

    Do you have experience with clients in my specific situation?

    This is the one most people skip. Tax professionals specialize even when they don't advertise it — some focus on W-2 employees, some on real estate investors, some almost exclusively on small business or specific industries like trucking. Ask what their typical client looks like. If the answer doesn't sound like you, that's useful information.

    What credentials do you hold and how can I verify them?

    A CPA's license is verifiable through the state board, an EA's through the IRS. Anyone who gets evasive about this question is a red flag on its own.

    What's included in your fee, and what costs extra?

    Some firms quote a base fee and add charges for each state return, each schedule, each amended return. Others include everything flat. Neither is wrong, but know which one you're dealing with before you commit.

    How do you communicate with clients during the year?

    Tax questions come up throughout the year, not just at filing time. Ask how mid-year questions are handled, whether quick calls are billed separately, and how quickly they typically respond.

    What do you need from me to make this work well?

    Someone who's done this many times can tell you clearly and specifically. A vague answer about "just send over your documents" signals less organization than a real checklist.

    Have you dealt with my state's specific tax requirements?

    Federal law is the same everywhere; state law isn't. If you're in a state with unusual rules — Washington's B&O tax, for instance — someone who works in that territory daily has depth an out-of-state virtual firm may lack.

    What happens if I get audited?

    Basic preparers without a CPA or EA credential generally can't represent you before the IRS. A CPA or EA can, at every level. Know the answer before you need it.

    Red Flags Before You Hire

    They guarantee you a refund before seeing your documents — no legitimate professional promises an outcome before reviewing your situation. They charge fees based on your refund size — an IRS-flagged practice, since it incentivizes inflating the refund rather than filing accurately, and you're the one who signs the return. They can't clearly explain what they'll actually do for you, in plain language. They have no verifiable credentials or professional presence you can confirm. And they're not asking you questions — a professional who never asks about your business structure, income sources, or major transactions isn't doing tax planning, they're doing data entry you could get cheaper elsewhere.

    Red Flags During the Relationship

    They miss deadlines without telling you — extensions exist and life happens, but finding out about a missed filing from the IRS instead of from your accountant is a serious breakdown. You don't understand what was filed on your behalf — your signature makes you legally responsible for it, so you should understand the big picture even if not every line. They're unreachable outside of tax season — questions come up in August about a purchase, in October about quarterly payments, in November about year-end planning, and a professional who vanishes between filing seasons isn't delivering full value. Your situation keeps getting more complex but the conversation never changes — if you've gone from sole prop to S-Corp, added employees, bought equipment, and taken on a rental property, and the advice is still just the same forms with updated numbers, someone isn't paying attention. And if you get an IRS notice and they're slow to respond — some notices have response deadlines of 30 days or less, and this is exactly the moment a professional should be moving fast, not the moment to discover they're hard to reach.

    The Quiet Red Flag That Costs the Most

    They never tell you anything you didn't already know. This is easy to miss because nothing feels broken — but a good tax professional is proactive, reaching out before year end about moves you can still make, flagging law changes that affect you, asking about next year's plans before they become last year's missed opportunity. If every interaction starts with you reaching out, and you've never once gotten a message that opened with "I was looking at your situation and wanted to flag something," you may be paying for compliance and getting nothing else. That's a filing service, not a partnership.

    What to Do If You Recognize These Signs

    Don't panic — most of this is fixable. Get copies of your last three years of returns and have them reviewed, either yourself or by another professional, so you understand what was actually filed. If you find errors, amended returns are an option. If you owe money you didn't know about, there are paths — payment plans, penalty abatement, offers in compromise — depending on your situation. And then find someone better.

    Many of the people who call us have been burned before — it's one of the more common reasons people reach out, not because tax season is approaching but because something felt wrong and they wanted a second opinion. If you want a fresh set of eyes on your situation, that conversation costs nothing to start.
