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.

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!

Not a fly by night firm

I had the experience of dealing with one of those TV advertised firms several years ago. What a difference. I remember Kaymar calling back form his vacation after I received a letter from the IRS stating I missed a payment. His immediate response and willingness to calm me down was greatly appreciat...ed. However, that is not why I am writing. He is an excellent lawyer who took hundreds of thousands of dollars of tax debt ad made it disappear in a period of one year. Two years of medical mishaps may have undermined me but Kamyar helped me get a new start.
