We are extremely grateful to do business with James Castaldo CPA & Associates. We found them through a Google search and were highly impressed with their reviews. As new small business owners, we made mistakes and also spent many years building our business. With so much time spent on building a brand we relied too much on previous accountants who created an absolute accounting mess that cost us thousands of dollars. We've been fortunate to work with Will, Justin, and Drake. Will did an amazing job cleaning the mess left by the previous accountant. I find everyone at Castaldo CPA to be very professional

I was referred to James Castaldo by a good friend. They definitely did not steer me wrong. I have been bringing my taxes to him at the Smithtown location for the past few years, including this season. James has always done excellent work, and is very thorough and helpful explaining any issues. The associates, namely Will and Justin, provide the same experience, and I consider it a testament to the quality of the business to see their familiar faces each year when I return. I highly recommend James Castaldo CPA and Associates! Thank you guys!

I am SO grateful for Justin at James Castaldo CPA! I started my own business last year, so this is my first year doing business taxes, and it is so stressful!! Justin was amazing and patient at helping me with my Quickbooks. He told me what changes he made, and why, and helped set me up correctly for the next year. To me, it was very important to have open, easy communication, and he provided that. As a new business owner, just knowing that you have someone dependable to help you along the way is a great relief! I have already recommended him to my clients and friends!
