How to Choose a Tax Attorney in Arizona

If you are facing a tax problem, choosing the right professional matters — and the first decision is what kind of professional you need. A tax attorney is a lawyer who focuses on tax law and can represent you in Tax Court, handle audits, and manage serious collection matters. A CPA is an accountant who is excellent for tax preparation, bookkeeping, and planning, and can represent you before the IRS on most matters, but cannot represent you in Tax Court. An enrolled agent is licensed by the IRS to represent taxpayers, often at a lower cost, and is a good fit for straightforward issues. For complex disputes, large balances, or anything that might end up in court, a tax attorney is usually the right choice.

Start by looking for an attorney whose practice actually focuses on tax law, not someone who handles the occasional tax question alongside a general practice. Tax rules are complicated and change often, so someone who deals with IRS matters regularly is far more likely to be familiar with the issues you are facing. Ask specifically about their experience with cases like yours: Have they handled audits? Installment agreements? Offers in compromise? How often do they deal with the IRS? An attorney who regularly practices before the IRS will understand its procedures, timelines, and personnel in a way that a generalist will not.

Check that the attorney is licensed to practice in Arizona by verifying their bar status through the State Bar of Arizona. You may also want to look for additional credentials, such as an LL.M. in taxation, though credentials alone do not guarantee a good fit. Equally important are the red flags to watch for. Be wary of anyone who guarantees a specific outcome — no honest attorney can promise the IRS will accept an offer or drop a case. High-pressure sales tactics, demands for large upfront fees before any work is described, or reluctance to put the fee arrangement in writing are all reasons to keep looking.

Ask about fees in detail before you hire anyone. Tax attorneys typically charge in one of three ways: hourly, flat fee, or contingency. Hourly billing is common for audits and disputes, and rates vary widely by experience and location. Flat fees are often used for routine matters like setting up an installment agreement. Contingency fees — a percentage of what you save — are rare in tax work and are prohibited for preparing original tax returns. Get the fee arrangement in writing in a retainer agreement that spells out what is covered, what is not, how billing works, and what happens if the scope of work changes. A clear written agreement protects both sides and helps avoid surprises later.

Most tax attorneys offer an initial consultation. Use that meeting to ask practical questions: What experience do you have with cases like mine? What are my options? What would you expect the timeline to be? How will we communicate, and how quickly do you return calls? Pay attention to whether the attorney explains things clearly and answers your questions directly. If you hire them, they will likely ask you to sign IRS Form 2848, a power of attorney that authorizes them to speak with the IRS on your behalf — this is standard and lets them handle correspondence and phone calls so you do not have to.

Trust your judgment. You will be sharing personal financial information with this person, so comfort and communication matter as much as credentials. If something feels off, it is fine to meet with more than one attorney before deciding. The right fit is someone who is experienced, transparent about fees, and communicates in a way you understand.
