How to Find a Good CPA: Interview Questions and Red Flags

Tax information is for educational purposes only and does not constitute tax advice. Consult a licensed tax professional for your specific situation.

A good CPA does more than file your return — they find deductions you miss, help you plan for the future, and keep you compliant. A bad one can cost you money through missed opportunities or, worse, trigger an audit. Here is how to find the right one.

When You Need a CPA vs. DIY Software

Situation	Software May Be Enough	Consider a CPA
Simple W-2 return	Yes	Usually not needed
Self-employed, under $50K	Depends on comfort level	Recommended first year
Self-employed, over $100K	Unlikely	Strongly recommended
Rental properties	Possible with good software	Recommended
Business entity questions (LLC, S Corp)	No	Essential
Multi-state income	Challenging	Recommended
IRS audit or notice	No	Essential
Estate planning	No	Essential
Major life change (marriage, divorce, inheritance)	Risky	Recommended

Types of Tax Professionals

Credential	Can File Returns	IRS Representation	Typical Cost	Best For
CPA	Yes	Unlimited	$250–$1,000+	Complex situations, business owners, planning
Enrolled Agent (EA)	Yes	Unlimited	$150–$500	Tax-focused work, audits, back taxes
Tax Attorney	Usually via staff	Unlimited	$300–$500/hour	Legal disputes, tax court, complex estates
AFSP Preparer	Yes	Limited	$100–$300	Simple to moderate returns
Non-credentialed Preparer	Yes	None	$50–$200	Very simple returns

Key distinction: CPAs and EAs have unlimited representation rights before the IRS. Non-credentialed preparers cannot represent you in audits.

Interview Questions to Ask

About Their Practice

What is your specialization? (Look for experience with your specific situation — self-employment, real estate, crypto, small business)
How many clients do you serve? (More than 500 individual returns may mean less personal attention)
How do you handle communication? (Email, phone, portal — and response time expectations)
Do you handle tax planning or just compliance? (Planning saves more money long-term)
Who will actually prepare my return? (In larger firms, a junior staff member may do the work)

About Their Qualifications

Are you a licensed CPA in this state? (Verify at your state board of accountancy)
Do you have a PTIN? (Required for all paid preparers)
How do you stay current on tax law changes? (Should mention CPE/CE hours)
How many years have you been in practice?
Do you have experience with [your specific situation]?

About Fees and Process

How do you charge — flat fee, hourly, or per form? (Flat fee is most predictable)
What is the estimated cost for my return?
Are year-round questions included in the fee?
What happens if I get audited? (Do they offer representation? At what cost?)
When will my return be completed?

Red Flags to Watch For

Avoid CPAs Who:

Promise a specific refund amount before seeing your documents — No honest preparer can guarantee results without reviewing your situation
Charge based on a percentage of your refund — This creates an incentive to inflate deductions or credits
Will not sign the return — Paid preparers are legally required to sign and include their PTIN
Suggest claiming deductions you cannot document — This is a sign of aggressive (potentially fraudulent) preparation
Do not have a PTIN — It is illegal to prepare returns for compensation without one
Are unreachable after filing — A good CPA is available year-round, not just during tax season
Push you toward cash payments with no receipts — Suggests they may not be reporting their own income
Have disciplinary actions — Check your state board of accountancy for complaints or suspensions
Do not ask you many questions — A thorough preparer needs to understand your full situation
Miss obvious deductions or credits — If they do not ask about retirement contributions, HSA, or education credits, they may not be thorough

What to Expect in Terms of Cost

Service	Typical Cost Range
Simple individual return (W-2, standard deduction)	$150–$300
Itemized individual return	$250–$500
Self-employed (Schedule C)	$300–$600
S Corporation return (Form 1120-S)	$500–$1,500
Partnership return (Form 1065)	$500–$1,500
Tax planning session	$200–$500/hour
IRS audit representation	$150–$400/hour
State return (additional)	$50–$200 per state

Costs vary significantly by location (higher in major metros) and complexity.

Building a Long-Term Relationship

The best CPA relationships are proactive, not reactive. Look for a CPA who:

Reaches out before year-end with planning recommendations
Suggests entity structure changes when appropriate
Stays on top of legislative changes that affect you
Reviews your withholding and estimated payments mid-year
Helps you understand your return (not just signs and files)
Responds to questions within 24–48 hours during non-peak times

Key Takeaways

Look for a CPA or EA who specializes in your type of situation (self-employed, real estate, business, etc.)
Verify credentials through your state board of accountancy and the IRS preparer directory
Ask about fees upfront — flat fees are the most predictable
Avoid anyone who promises specific refund amounts, charges based on refund percentage, or refuses to sign the return
A good CPA provides year-round value through tax planning, not just annual filing
The cost of a CPA is often offset by additional deductions and credits they identify
