Costello Tax Associates
“I highly recommend hiring John for MA state and federal tax returns. We live in Somerville and found him randomly as we drove by his office. He has now been preparing our complicated tax returns for over 10 years and we've never seen a mistake. Yes, his consultation time is limited during the tax filing season, but he and his team are busy getting all our returns done on time! I appreciate his prompt turnarounds and accurate work.”
