Sinco Data Processing Systems - Tax preparation service in Uniondale - 779 Park Ave, USA

I have been going to Sinco Data Processing Systems for years now. Since day one, they have treated me with complete respect on such a Professional level. Whenever I had any questions, they are always available answering them promptly. I appreciate and Thank them for always being there for me and my Family. I highly Recommend Sinco Data Processing Systems to all. We are completely satisfied and will continue with our business always.

My husband and I have been with Mr. Sinclair for a couple of years and have no complaints. Every time we meet with him he teahes us something new. Every visit is a lesson. He's an honest family man who cares about everyone that walks in his office.

I been coming here for 6 yrs .. I never had any issues. They are very welcoming.. I highly recommend to anyone who's looking for someone to do there taxes...

ITS A RED FLAG WHENEVER A TAX PREPARER TELLs YOU " WE DON'T KNOW HOW MUCH IT WILL COST BECAUSE IT DEPENDS ON HOW MUCH YOU MAKE." TRY THEM AT YOUR OWN RISK.

Best on Long Island.

Always on point
