      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.

      RA's Review Sourced from Google

      As an accounting firm I would give them 1 star. I recently discovered a litany of deductions they failed to consider. You will be given an EA, which is just a glorified tax preparer. They will know nothing and be slow to reply. You might as well get your taxes done by H&R block or a proper independent CPA. If these folks do your taxes, get prepared for a larger tax bill. I strongly advise against it.
