Sundack CPA is a tremendous asset to my small business. From the very beginning, Jarett and his team have helped me with my tax planning, payroll processing services, 1099 preparation and my individual returns. I highly recommend any small business or self-employed independent contractor consider Sundack CPA when deciding who to trust with their financials.

If there were an option for 7 starts we would give it. Not only is Sundack CPA along with Jon and his team running the best accounting firms in New York but they have far exceeded all/any expectations one can ask for from an accounting perspective. Jon and his team take the time to not only make me feel important as a client but heard. They listen, and help with solutions. I consider Sundack CPA my in-house CFO with the tremendous expertise and advice they provide. I have already referred family and will continue to do so. I look forward to a fruitful partnership with Sundack CPA on my side. Thanks for all you do!

I am a the owner of a professional services business and Sundack CPA has been my account for several years. As my accountants, Sundack CPA handles my monthly reconciliations, quarterly tax strategy and planning meetings and files my corporate and personal taxes. I could not be happier with the high level of service and detail that Sundack CPA provides. Prior to working with Sundack CPA, I was working with an accountant who was more of a solo practitioner. While we were friends, we were only meeting yearly to discuss my tax returns. When Sundack CPA reviewed the returns being filed by my previous accountant, Sundack CPA discovered that the previous accountant was taking liberty with deductions which left my business and personal assets exposed. Not only did Sundack CPA resolve the issue, but, by being more involved in the monthly reconciliation of my accounts and quarterly meetings, we were able to develop a tax strategy that saved me money without taking risks. If your accountant is not looking at your business and meeting with you every quarter like Sundack CPA does, than, it is time to look for new representation, in which case, you cannot go wrong with Sundack CPA!
