Zahaer Fallahi is a very knowledgeable and honest tax lawyer. I have sat in numerical presentations on various aspects of tax laws. Also, on few occasions, Zaher provided me with legal counsel. Typically, tax lawyers will end their recommendations with: Check with your CPA. The good thing about Zaher is both a layer and CPA. So, you will get complete advice.

Response from the owner:Dear Babak: Thank you so much for your kind words and thoughtful review! I'm truly grateful for the opportunity to assist you with your tax and legal matters. It's always my goal to provide clear, comprehensive guidance, and I'm glad to hear that you found the dual perspective as both a lawyer and CPA helpful. Your trust means a lot, and I look forward to continuing to support you whenever you need. Warm regards, Zaher Fallahi, Attorney At Law, CPA and Team

He has successfully handled intricate tax scenarios with impressive competence, ensuring compliance while optimizing financial outcomes.

I highly recommend Zaher Fallahi’s services for anyone requiring expert advice and reliable management of tax-related issues, both domestic and international.

I approached Mr. Fallahi seeking legal advice and guidance concerning the sale of property I had inherited overseas through a life estate. I wanted to make sure that the sale of my property, along with the transfer of the proceeds to the United States would be in total conformity with Office of Foreign Assets Control (OFAC), US Laws of Sanction, US Tax Laws, and US Banking Laws and Procedures.. I quickly found Mr. Fallahi to be a very gracious, friendly, approachable, knowledgeable, and dedicated attorney. Not only would Mr. Fallahi ask dozens of relevant questions to familiarize himself with the intricacies of your unique situation, he would also go to great lengths to thoroughly and clearly explain the entire process, so that you would have total clarity in every step of the way. Mr. Fallahi’s expert knowledge did provide me with great peace of mind in this undertaking. He does not offer “one size fits all” solutions or advice. He makes sure that his legal guidance is tailored to your unique situation. While Mr. Fallahi offers a wide array of legal and tax services, he would only offer those services he believes would be necessary and beneficial to your individual case, thus avoiding unnecessary cost to you. Thanks to Mr. Fallahi, my transaction went smoothly and without any headaches. Navigating the complex world of OFAC, banking, and tax regulations and implications related to the personal remittance of a foreign asset is by no means a simple task. It requires expert advice and guidance; and I am very grateful to Mr. Fallahi for his caring, professionalism, insight, and sound legal advice.

Response from the owner:Dear Captain Ali: Thank you so much for your thoughtful and generous review. It was truly a pleasure assisting you with your legal and tax matters involving sale of your international property and compliance with the U.S. Treasury’s Office of Foreign Assets Control (OFAC) Regulations and U.S. International Tax Laws. I’m glad to hear that our guidance helped bring you peace of mind throughout what can indeed be a complex process. Your kind words about my approach and professionalism mean a great deal to me. I’m always committed to providing tailored, clear, and practical legal advice, and I’m grateful for the trust you placed in Zaher Fallahi, Attorney At Law, CPA. Wishing you continued success and all the best in your future endeavors and flights, Captain. Warm regards, Zaher Falahi, Attorney At Law, CPA, and Team

I had an excellent experience working with Dr. Zaher Fallahi to recover four years of tax withholdings. His deep knowledge of tax law and clear communication made the process smooth and stress-free. Not only did he help retrieve the withheld amounts, but the IRS also paid additional interest thanks to his thorough handling of the case. I highly recommend his services for anyone dealing with complex tax matters.

Response from the owner:Thank you for your generous words, Mr. Alam. It was truly a privilege to be of service to you. I thoroughly enjoyed working with your esteemed team and felt like an honorary member throughout the process. Your collective determination played a key role in persuading the IRS to resolve the matter in your favor. My warmest regards to you, your team, and the honorable Chairman of the Board. Sincerely, Zaher Fallahi, Tax Attorney, CPA
