Outstanding work!

I have had the privilege of working with Kamyar Mahdioun since 2014, during what was one of the most stressful and unjust periods of my life. I was unexpectedly and aggressively audited by both the federal and state governments for reasons that had no legitimate basis. At the time, I felt overwhelmed..., helpless, and unsure how I would navigate the legal and financial implications that threatened not only my livelihood but my home and everything I had worked so hard to build. From the very beginning, Kamyar brought a sense of calm, clarity, and control to a situation that felt anything but. He approached my case with compassion, deep expertise, and an unwavering commitment to justice. His thorough understanding of tax law, combined with his strategic thinking and attention to detail, gave me immediate confidence that I was in the right hands. Over the years, Kamyar has not only helped me resolve the audit in my favor—saving my home and protecting my assets—but he has continued to be a trusted advisor for all matters related to my taxes and financial planning. His integrity, professionalism, and genuine care for his clients are unmatched. I can honestly say that Kamyar Mahdioun didn’t just help me through a difficult time—he quite literally saved my life and gave me peace of mind when I needed it most. I am deeply grateful for his support, and I wholeheartedly recommend him to anyone in need of a brilliant, trustworthy, and dedicated tax attorney. Kamyar is one of a kind, and I cannot imagine where I would be today without his guidance.

Responsive, Professional, Knowledgeable and Good value

My husband just died. He left me various tasks to do for him. There is a problem that prevents me to do one of the tasks. It is about tax. I am not really sure who can I trust, who can I ask. I prayed hard for solution. Then one sleepless night, I was in the front of my computer. I googled " Tax Law...yer near me". The very first name came out was his. I read the reviews . He is their saint and savior! And then I thought he could be my savior too. I hit my keyboards and started to email him. I told him what bothers me. I sought for his professional advice... Hit send and went to sleep consoling and telling myself not to expect and that he may not waste his time to me. I was wrong, on the second day I got email from him saying " Please call me ". I was so surprised and relieved . He is very accommodating, professional and very straight forward . He taught me what to do and even guide me how to do my solution. He spent time and double checked if am doing it right. What a man! He doesn't know me but he accommodated me and didn't take anything in return. Since then, I spread the news. Telling anyone to get this lawyer if they will have problems in tax. Not all heroes wear capes !!

Highly Recommend Attorney Kamyar Mehdiyoun

My wife and I consider Attorney Kamyar a blessing to our family, a true God sent. We owe over $100,000.00 to IRS and State of Maryland. After a job loss and struggling to pay the taxes, threats of liens on our property and bank accounts, we realized it was out of our control and we needed help. We ha...d considered other firms that sent out mailings and advertised on television, but did not feel comfortable or trust organizations out of state and felt it would better for us if we could meet the attorney face to face. When we met with Kamyar, we felt at ease and though there were no guarantees we felt we could trust him to do his best for us. He was very approachable and answered any questions without making us feel bad about us being in this situation. As soon as he started working on our behalf, the threats and request for payments stopped. We were ecstatic. Any time we called him, if we had to leave a message, he returned our call without having to wait days. By the time Kamyar was done, the IRS put us in non-collectable status, and the Comptroller of Maryland put us on a 33 month repayment plan where we pay them under $150 per month. We would highly recommend if anyone has a tax problem, CALL Kamyar Mehdiyoun!

Grateful for an amazing settlement with the IRS

For over 13 years, I struggled with a complex tax issue that many in this industry were unable to help me resolve. My tax issues stretched from the states of California and Georgia and the Internal Revenue Service (IRS). 1. My tax liability with the IRS was over $123,000. 2. The State of Califo...rnia erroneously charged me an untold amount of taxes when I was not living or working there. The state passed liens on my assets and collected more than $14,000 from my pay and my bank account. I am extremely happy to have discovered Mr. Mehdiyoun. He is one of the few lawyers with whom I found myself to be very comfortable. He is extremely knowledgeable in his field, professional, honest, and his fees are very reasonable considering his expertise. He does not mislead nor does he promise things that he cannot deliver. During my initial intake, he promised to resolve my tax issues in 6 months. I was pleasantly surprised to see that he was able to deliver on his promises in exactly six months. 1. In exactly 6 months the Mehdiyoun Law Firm coordinated with the IRS to settle my account and reduced my liability to only $240.00. You can do the math of the amount of savings he worked out for me. 2. Although the state California tax issue was not part of the deal, he voluntarily decided to help me with that state. He communicated with the State of California who later rescinded the liens on my assets and admitted of their error. Prior to the Mehdiyoun Law Firm, everyone I approached did nothing but take my money and waste my time. While others stole my money for over 13 years without a resolution, he was able to work with the IRS to do it in 6 months. I was extremely fortunate to find someone so honest and extremely knowledgeable. During the process, he was also very responsive to my email and phone inquiries. Basically, I am immensely grateful to Mr. Mehdiyoun expertise in the intricacies of US tax laws and transactions with the IRS. His are by far the best in this industry. His professionalism is second to none.
