How to Choose a Tax Advisor Specializing in Retirement Planning

Tax preparation looks backward. It takes last year's 1099s, W-2s and statements and reports them correctly on a return. Tax planning looks forward. It models what next year and the following ten years of taxable income will look like and recommends moves with dates attached. Both are real work and both are worth paying for, but they are different deliverables, and many retirees have a preparer they like and no planner at all. The first screening question is simply which of the two you are hiring, and whether one person or two people will do each.

The title does not help you here. "Tax advisor" is not protected, so anyone can use it. What is regulated is narrower. Anyone paid to prepare federal returns must have a Preparer Tax Identification Number (PTIN) and sign the return as preparer. Unlicensed preparers have limited rights to represent you before the IRS, while CPAs, Enrolled Agents and attorneys have unlimited representation rights (confirm the current scope with the IRS). That distinction matters the day you get a notice, not the day you hire.

Each credential tells you something different. A CPA is licensed by a state board of accountancy (in Arizona, the Arizona State Board of Accountancy) after education, the Uniform CPA Examination and experience, and the credential covers audit, accounting and tax broadly. Many CPAs concentrate on business clients rather than retirement. An Enrolled Agent is a federal credential issued by the IRS under Circular 230, earned through the three-part Special Enrollment Examination or qualifying IRS experience, and the whole credential is tax. A CFP® is awarded by the CFP Board and covers retirement, investments, insurance, taxes and estate at a planning level, but most CFP professionals do not prepare returns. Each is useful for something. None proves the person is good at retiree tax planning.

Verification is free and quick. Check a CPA license through the state board of accountancy or CPAverify. Check an Enrolled Agent or any paid preparer on the IRS Directory of Federal Tax Return Preparers with Credentials and Select Qualifications. Check a CFP® on the CFP Board's online verification tool. If the person also gives investment advice, look up the firm on adviserinfo.sec.gov and a broker on brokercheck.finra.org. Confirm the current official lookup for each, since agency sites change, and read what comes back: status, disciplinary history, and the firm they actually work for. A directory list of flat-fee firms is covered in a separate article on finding a flat-fee retirement tax planner, so this page stays on how to evaluate whoever you find.

The interview is where retirement competence shows up. A planner who does this work regularly can tell you what share of clients are retired or within ten years of retirement, can show a sample multi-year projection with names removed, and can explain tradeoffs without a script. Listen for specifics: how they size Roth conversions into bracket space before RMDs and Social Security begin, how they watch the Medicare IRMAA two-year lookback (the first 2026 tier is $218,000 MFJ or $109,000 single, based on 2024 income), what they do about the ACA subsidy cliff before 65, and how they handle Q4 year-end moves. If they cannot explain a Roth conversion tradeoff or IRMAA in plain English, they are likely a preparer, which may be fine if that is what you are hiring.

Fee structure comes in a few forms: hourly, per-return, annual retainer and project fee. Amounts vary widely, so compare what each fee includes rather than the headline number. Ask whether the fee covers the return, the projection, the Q2 and Q3 check-ins, and IRS notice support. Then ask whether they earn anything from products they recommend. A flat fee paid by you removes one conflict, but it does not by itself prove tax skill. Quoting a fee based on the size of your refund, or promising a specific savings figure, is a warning sign in any structure.

Finally, check how the tax professional and the investment advisor work together, because the best retirement tax plan fails if no one executes it. The planner should hand a written action list with dates to the investment manager (for conversions, harvesting, QCDs and withdrawals) and to the preparer (for estimates and filing). Ask who owns each step, how often they talk, and whether you will be copied. If your estate attorney is involved, the same loop applies to beneficiary designations and inherited IRA planning under the 10-year rule.

Decide first what you are hiring. If you want a return filed accurately and your situation is straightforward, a credentialed preparer with a good record may be all you need. If you hold $1.5 million or more mostly in pre-tax accounts, expect Roth conversions, RMDs, IRMAA and possibly an ACA subsidy decision to matter, and you want a planning deliverable, not only a return.

Run the screen the same way with every candidate. Use the checklist below, verify credentials before the call rather than after, and ask each person for a sample projection. Comparing three answers to identical questions tells you more than any directory ranking. Keep notes on who answered with documents and specifics and who answered with reassurance.

Evaluate your current professional with the same list. If they prepare your return, talk to you before year end, show you a multi-year projection, and coordinate with your investment advisor, you may not need to change anything. If they only appear between February and April, you can ask them to add a mid-year projection and a Q3 conversion review first, and switch only if they will not or cannot.

For Arizona residents, confirm that the person is comfortable with the state side as well: Arizona's flat 2.5% income tax, no state tax on Social Security, and community property rules that can affect basis at the first death. These details are easy to get right and easy to overlook if the advisor serves mostly out-of-state clients. If you are weighing how a flat-fee fiduciary arrangement differs from other pay models, the Why Flat Fee page linked below explains it.

• Hiring on the title "tax advisor," which is not protected, without verifying a CPA license, EA status, or PTIN.
• Assuming a good preparer is also a planner, and then discovering in April that no one projected the next year.
• Treating a credential as proof of retirement expertise when a CPA, EA or CFP® can each practice mostly in a different lane.
• Skipping the free official lookups and relying on a website, a referral, or a business card.
• Choosing on price alone, or on a fee tied to your refund, instead of comparing what the fee includes and whether the preparer will sign the return.
• Accepting tax advice from someone who also sells insurance or annuities without asking how they are paid on those products.
• Leaving the tax professional and the investment advisor in separate silos, so the recommended moves never get executed on time.
