How to Vet a Tax Professional (Beyond Google Reviews)
Asking 'How much do you charge?' is the wrong question. Here are the 5 questions you should ask to find a true tax partner.
Most people pick a CPA based on two things:
- Are they nice?
- Are they cheap? NICE and CHEAP are great qualities for a barista. They are terrible filters for a tax strategist. You want COMPETENT and PROACTIVE.
Key Takeaways
- Question 1: 'How often will we talk?' (If the answer is 'Once a year', run).
- Question 2: 'Do you specialize in my industry/situation?' (Generalists miss niche deductions).
- Question 3: 'How do you exchange documents?' (Email is insecure; look for modern portals).
- Question 4: 'Who actually prepares the return?' (Is it outsourced or done in-house?).
The “Litmus Test” Question
Ask this: “Can you tell me about a tax saving strategy you suggested to a client similar to me last year?”
- Bad Answer: “Uhh, well, we help them get all their deductions.” (Vague).
- Good Answer: “We had a client with high W-2 income, and we helped them execute a Backdoor Roth and tax-loss harvesting to save about $4k.” (Specific).

Price as a Signal
If a CPA charges $300 for a business return, they operate on volume. They must spend less than 1 hour on you to make money. You cannot do tax strategy in 1 hour. Real planning involves evaluating moves like Solo 401(k) contributions, QBI deduction optimization, and estimated tax payment timing — none of which fit into a 60-minute appointment. Expect to pay $1,000+ for a return that comes with advice. It is an investment, not a cost.
The Communication Test
Your relationship with a tax professional should not be a once-a-year event. If the only time you hear from them is when they need your documents in March, they are a preparer, not a planner. The best advisors maintain a year-round cadence --- checking in at least quarterly to adjust estimated payments, harvest losses, or front-load deductions before year-end.
