      So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

      Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.

      Our company left Tandem HR when they hiked the prices in 2024. Apparently, they do not send employers, copies of W2's for companies that have left service. I'm supposed to reach out to each employee to get a copy. Nice job, for doing the one job you had.

      I started using Berndt CPA in 2017 as our outsourced bookkeeping and accounting provider for a mental health practice I owned. They made my life so much easier by digging in and figuring out how to most efficiently work with our contract requirements. Our CPA, Alicia Greer, is smart, efficient and always stays on top of new laws and contract policies to help us comply. When audit time came, I always felt confident as I knew all was in order. I continue working with them for my new practice and my personal taxes because the trust is there that it's going to get done and it's going to get done correctly. You won't regret working with the team at Berndt CPAs.

      I’ve been a tax preparation client of Berndt CPAs for over five years, and they’ve consistently delivered outstanding service. They’re incredibly organized, communicative, and make the tax process straightforward and stress-free.What sets them apart is their understanding of entrepreneurship. As a business owner, I’ve appreciated their ability to offer guidance that goes beyond compliance. They really get what it means to run on a personal and professional level.

      Been with the Monona Wisconsin office for close to 19 years. Informed them that I was changing CPA's to a different firm. Forward 1 year and my Sorge account made a mis-stake on my 2022 tax return cost me $16k with penalties interest to the IRS in 2024 because one of their accountants use the wrong number in a place by mis-stake and literally messed up my 2023 quarterlies, said I had $24k coming back and that we where going to apply that to the next years quarterlies, little did I know that was wrong and I get stuck paying, my new accountant says I should go after Sorge CPA for the $1000 + in penalties and interest, I look at it as I made the right move to find a different firm. The only reason I started looking for a different firm to begin with is their fee's just kept increasing and increasing over the years until it seemed like they were on the payroll monthly and I realize $4000 filings fee's on top of constant large monthly fee's for taxes is ridiculous. It now cost me a quarter of the cost that it did.

      Wendy Adams's Review Sourced from Google

      We have always used a CPA to prepare our taxes. This year, we planned to move to what we thought was a local, large firm and had chosen this organization. This was a huge mistake. First, they promised if all materials were submitted by 3/18 (ours were), they guaranteed your return would be completed on time. Not only did they fail to do this, they simply filed for an extension without ever letting us know. As it was getting closer to the date taxes were due, I reached out to ask about the status. When they indicated they weren’t going to meet the 4/15 deadline and had filed for an extension on our behalf, I asked if they were going to let us know if we owed taxes so we could pay without incurring interest and penalties. The tax preparer who had been assigned to us said she’d calculate an estimate. Later that day, she came back and said we should pay over $22k and just apply any overpayment to next year. We knew this was a gross over estimate and an utter display of incompetence. We called and attempted to escalate the issue but were told they only communicate using the app. We were never able to speak with anyone other than the Reception staff. We immediately pulled our business and went back to our old CPA. We estimated our own tax, which was over $13k less than they had indicated. I did lose my $100 deposit but they had the nerve to try to charge me another $400 for this incompetence and act like they did me a favor by waiving it. Please do not ever use this organization if you care about your financial wellbeing. We are two educated professionals who learned that this place can not be trusted.
