Our family had been going to James Castaldos CPA firm for years. The staff is highly knowledgeable and very efficient. I've had some severe tax complications, but James, Justin, and the team were able to help me recognize reality and put me at ease with proper tax planning, recommended solutions, and examined the way forward. Thank you, guys!!

We cannot say enough about this CPA firm. As a small business the individual attention they have given us has helped tremendously. James has taken the time on many phone calls and in person meetings to explain each step along the way ; from maximizing our revenue and helping budget so that we have been able to grow to explaining taxes and payroll rules. I was referred here after the previous firm , who apparently didn’t specialize in small business , or even answer the phone for That matter really didn’t help us for quite some time. We fully recommend James and his team !

Top notch. You get what you pay for here. If you have a LLC and/or foreign income this is the place to have your taxes done. James helped with a tax issue that many other CPA’s had zero knowledge of. You’re going to pay a premium price for filing, but you won’t be disappointed

James and his team have been incredible. They take a lot of pride in what they do and they are easy to work with.

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, organized and straightforward. I really wish that we would have found Castaldo CPA when we first opened our business; it would've saved us lots of money and headaches. If you're a new business owner, having the right accountant from the very beginning will make a world of a difference.

I have been bringing my taxes to him at the Smithtown location for the past few years, including this season.

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!!

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!
