Apr 11, 2022 Report
My family has used Mary Miller for over 20 years. I personally have used Mary Miller for the last 5. I have very basic taxes, 10-99, mileage, expenses, only takes a professional 20 minutes. Last year, when Mary Miller filed my taxes, it cost me around $120. Mary Miller was fully booked this year so they handed me over to another account, Kailey. Kailey charged me $325 for the same exact thing that Mary Miller charged me $120 to do last year.

When I asked how/why I was charged this much, they explained to me that I made more than I did the previous year so it took a lot longer.apparently 3 hours longer. They ended the conversation by telling me to go elsewhere, which I gladly did. If you do have to use them, only use Mary Miller.

I have been going to Miller Verchota for years now. Mary is very professional and so knowledgeable on tax law and auditing. The office experience from start to finish is smooth and flawless. Mary responds quickly to all emails and phone calls. I highly recommend this tax firm you cannot find any better CPA's. Sincerely Ginger Morton

Dec 11, 2021 Report
I was a client of Miller Verchota for several years. However, in 2018 they advised me on a Roth IRA conversion. Their miscalculation ended up costing me $20,000 in payments to the IRS on my 2018 federal return. Their daughter and employee Jamie Seda did our taxes. Quite frankly not even sure she is a CPA. As soon as I questioned them on this egregious error, they told me that I am no longer a client and needed to find another tax firm.

This was a few weeks before the IRS deadline of April 15th. I paid Miller Verchota good money for this advice and this is what I received in return. Very poor and neglectful advice. Never again. I would highly recommend avoiding Miller Verchota for any financial / tax advice or anything else for that matter.
