I found that asking my colleagues or 1099 CRNAs for local CPAs quite helpful. I think you need to interview the CPA on the phone and ask about experience working with medical providers who run a solo or 2 person small business. How aggressive is this CPA vs how conservative with deductions. You want to hire a CPA who fits in with your philosophy about the risk for audits. The more aggressive the deductions the more likely you won't survive the audit. I chose a middle ground CPA who reminds me often when I step over the line. I like to know the risk I am taking with each deduction: remember with tens of thousands of new IRS agents being hired in 2023 the chance for an audit is going way up. Hence, be prepared to pay the fine and defend the big deductions.
I generally like to limit my exposure to no more than $10,000 in "back taxes" owed due to deductions being denied in case of an audit.
