Tax Audit Representation

Trusted Tax Counsel with CPA Precision and Legal Insight

Zaher Fallahi, Attorney at Law, CPA, provides integrated legal and tax representation before federal and state taxing authorities. Combining the analytical discipline of a Certified Public Accountant with the strategic perspective of a seasoned attorney, Mr. Fallahi delivers comprehensive, results-driven representation in complex tax audits, offshore compliance, and tax resolution matters.

Prior to establishing his own firm in 1992, Mr. Fallahi worked with a nationwide professional firm and a major government agency, gaining invaluable experience in tax, regulatory, and financial systems. Since founding his CPA firm, he has collaborated closely with a mid-size law firm, providing a rare blend of legal and accounting expertise. This dual perspective allows him to handle each client’s matter with depth, accuracy, and strategic foresight — integrating legal advocacy with technical tax analysis at every stage.

For over three decades, Mr. Fallahi has represented individuals, businesses, estates, and fiduciaries before the Internal Revenue Service (IRS), California Franchise Tax Board (FTB), Employment Development Department (EDD), and the California Department of Tax and Fee Administration (CDTFA), formerly the State Board of Equalization. Our firm provides complete representation throughout the administrative process — from initial audit inquiries and examination conferences to appeals, settlements, and coordination with litigation counsel before the U.S. Tax Court or state tax tribunals.

We prepare detailed written responses, evidentiary submissions, and reasonable cause arguments to defend our clients’ positions with precision and professionalism. Our objective is to resolve tax controversies efficiently and favorably while protecting taxpayers’ procedural rights and minimizing exposure to penalties and liabilities. Drawing upon decades of experience in both federal and state tax controversies, our firm provides strategic, well-reasoned, and effective representation in even the most challenging cases.

Offshore and International Tax Compliance

Over time, our practice has expanded to include complex offshore and international tax compliance matters. We have successfully assisted numerous clients in rectifying prior noncompliance involving foreign income, accounts, and asset reporting. Our representation includes participation in:

These programs — designed for taxpayers whose non-compliance was non-willful and who are not under current IRS examination or criminal investigation — provide structured and protective pathways to full compliance, often with reduced or eliminated penalties. When executed properly, they enable taxpayers to come into compliance confidently and lawfully under U.S. tax procedures.

Tax Collection and Resolution Matters

In addition to audit and compliance cases, our firm represents clients in federal and state tax collection and resolution proceedings, including:

Each engagement begins with a detailed analysis of the facts, supporting documentation, and governing law. We prepare comprehensive financial disclosures, legal memoranda, and reasonable-cause statements tailored to each client’s situation. Our extensive experience in working directly with revenue and appeals officers allows us to achieve fair, practical, and favorable outcomes for clients facing complex tax challenges.

Matters involving tax preparation, prior-year returns, or compliance restoration are handled through our affiliated Zaher Fallahi CPA, ensuring seamless coordination between legal representation and accounting support.

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.

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
