Tax lawyer and IRS problem resolution tax attorney, Kamyar Mehdiyoun, is dedicated to providing high quality legal advice at an affordable cost. Since his graduation from Georgetown University Law Center with a Master of Laws degree in Taxation, he has helped individuals and small businesses in tax controversy matters such as tax audits, tax debt relief, payroll tax problems, IRS audits, tax liens and levies, unfiled tax returns, IRS offers in compromise and tax penalty issues. 


Although, most of our clients are concentrated in Washington, D.C., Maryland and Virginia, we help taxpayers nationwide through effective representation before the IRS.


High-Quality Tax Advice and Legal Help

Our firm’s exclusive focus is providing high quality but affordable legal advice in tax controversy matters. Our clients often come to us with tax problems and tax disputes ranging from federal tax and IRS problems to those involving state tax issues in Maryland (MD), District of Columbia (DC), Massachusetts (MA) and New York (NY). They seek help and legal advice relating to: state and IRS tax audits, state and IRS tax debt relief, state and IRS property seizures (including bank account levy and wage or salary garnishment), IRS back taxes and tax debts including tax penalty and interest, innocent spouse relief, IRS delinquent tax liabilities, tax obligations that are in the IRS tax collection process such as a tax lien or a tax levy and statue of limitations issues involving a state or IRS notice of tax delinquency.


Taxation law is notoriously complex and confusing. Early intervention by an experienced IRS tax debt relief lawyer often leads to early, inexpensive and favorable resolution of your tax dispute with the IRS or a state taxing authority. The same problem if handled by a non-specialist will very likely result in tax penalties, expensive tax liens, tax levies and even civil and criminal tax investigation and litigation.


We help our clients in the course of their dealings with the IRS and with state taxing authorities. These matters often begin when individual taxpayers or small businesses learn that they have been targeted for a state or an IRS tax audit or when they receive a tax bill or a notice of tax delinquency. We continue our legal assistance by representing our clients before the IRS in any tax debt collection actions such as a tax lien or tax levy and counseling them throughout any litigation in the United States Tax Court.

Our mission is to help our clients with complex tax problems. Tax disputes with the IRS or with state taxing authorities often disrupt personal lives of individuals and interfere with efficient operation of businesses. Nationwide, DC, MD & VA

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 Lawyer 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 !!

Kamy Goes the Extra Mile
While it's clear to me that Kamyar deals with much larger cases than mine, he gave us every indication that our state and Federal tax concerns were of the highest priority to him. He has been so thorough, so proactive, so friendly and so helpful in every imaginable way, helping us navigate the process for offers-in-compromise. He made a potentially stressful situation so easy to navigate, ensuring our compliance with state and Federal regulations and arriving at a very desirable outcome, saving my family tens of thousands of dollars. We were amazed at the results and give him our highest recommendation and praise.

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 had 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 California 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.

He saved me from a horrable tax problem
I've been working with Kamyar for 3 years. The IRS had a tax lien against me for more than $200,000. They kept going back and fourth with me. The day I hired Kamyar was one of the best days of my life, he saved me from this HUGE tax bill. Unlike most attorneys you call and never can reach them, Kamyar always answer his phone. If he doesn't answer he will call you back or email. It was a great experience working with him and I know I can be hard and impatient most of the time. LOL I just want to tell all of you who's reading this, if you're in need of a tax attorney Kamyar is the BEST. Thank you SO MUCH Kamyar from A List Hair & Wardrobe Stylist CoCo La Rue

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 appreciated. 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.

First class tax attorney.
For the past two years Mr. Mehdiyoun represented me with my tax issues. In short.. I found him to be very professional and very good in what he does. Today, September 10, 2012 my case has been resolved successfully. I am so happy! I highly recommend Mr. Mehdiyoun to anyone in need of help dealing with the IRS. I listened and followed his advice each step of the way and I am glad I did. He updated me periodically in regards to my case and I never felt rushed when I had questions for him. Today, I feel so relieved and so happy that he represented me. His fees were very reasonable. If you want a peace of mind .. Mr. Kamran Mehdiyoun is the right attorney and I recommend him 100%.
