While unable to help, they spent an hour in the phone with us free of charge and we came away with valuable information. Appreciate their honest dealings
jedadiah roll's Review Sourced from Google
The level of incompetence these guys are allowed to operate at is appalling. These people will drop the ball in your taxes and try to charge you for fixing their mistake. I’ve never dealt with a worse company.
Trent Tolton's Review Sourced from Google
My bookkeeper unfortunately referred me to Anastasi, Moore & Martin, PLLC. These guys did my taxes for 3 legal entities and It has been a terrible experience for me all the way through. I have had 3 other separate accountants inform me Anastasi, Moore & Martin, PLLC have filed my taxes for 3 of my company’s incorrectly. It will cost me thousands of dollars in IRS fees to amend the mistakes these guys made.1.) Justin and Ryan do not inform you of how they are classifying your company with the IRS. In addition they DO NOT look at the secretary of state website to verify the type of legal entity you have established with the state for example they do not check who the members or managers are on the LLC or corporation, they do not check how your company is structured for example if you are a registered s-corp or c-corp, they just guess on it and try to file your taxes as fast as possible.2.) They filed my corporation as a sole proprietorship when I told them it was a corporation and it obviously is a corporation if they took 2 seconds to look on the secretary of state website and the word Inc.-Incorporated is literally at the end of my company name. Then Justin lies to me over email and states: I told them to file my corporation as a sole proprietorship-which does NOT make sense because even if I did tell them to file my c-corp as a sole proprietorship that would not be legal or ethical to file a corporation as a sole proprietorship3.) Justin and Ryan are both extremely unresponsive and when they do respond it’s with an attitude, they do not provide good customer service at all. Their secretary-Clara then sends my social security number over unsecured email to clarify if it is correct.

InlineAdam's Review Sourced from Google
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

We are proud to have been able to offer a beautiful Modernfold panel recovery job to give the walls a facelift to complete newly renovated meeting rooms at Deloitte in Rockefeller Plaza. Deloitte has always been such a great and dear client of ours! We look forward to continuing to work together in the future!
Alex Stackhouse's Review Sourced from Google
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.
