About Omid

Learn Omid’s areas of practice.

Omid Johan Shirazi co-founded K&S Law Group, P.C. as a partner and the head of the Firm’s Tax Controversy Practice in 2015. A practicing CPA for over 7 years, both in the public and private sectors, his practice focuses on federal, state, and international tax services for a range of clients, including domestic and international business entities and individuals. He has advised clients on income tax treaty implications, FATCA and FBAR filing requirements, federal and state inbound and outbound royalty, dividend, and interest payment, and tax-efficient transactions and structures.


Omid has also counseled a number of charitable and nonprofit organizations on incorporation, applications for federal and state tax exemptions, annual filing requirements and other tax issues.


Public & Public Sector Practice

Omid focuses his practice on tax controversy, tax planning, and complex transactional matters for businesses, individuals and professionals. When representing clients faced with complex issues, Mr. Shirazi draws on his legal experience at the IRS Office of Chief Counsel, as well as his background as a CPA with PriceWaterhouseCoopers and Squar Milner, to most effectively provide counsel and advise clients. Omid's background, both in private practice and at the IRS, provides him with the tools to assess the strengths and risks of each issue, negotiate favorable settlements with the government and, if necessary, litigate the matter before the appropriate court.

Best Tax Attorney in Orange County
Omid is passionate about his practice. His background is quite impressive and he demonstrates his talents and knowledge on day 1. He made me feel reassured and confident after stressful issues and visits from the IRS. I am endlessly appreciative of Omid and his firm. They saved my life and my family.

In 2016 I was in a world of tax turmoil. Not sleeping, constantly worried, when would the lien might occur or when was the garnishment hammer going to drop. Then it happened. I don't know what you would do when a IRS Agent knocks at your door, but for me it was polarizing. I didn't have a clue as what to do. Luckily, I wasn't home. The agent did have the courtesy to call me while she was standing at front door and sarcastically asked me for a check. What a jerky thing to do. I was given Omid's number from a friend and my life was changed. Omid put my wife and I at ease and assured us that things would get handled. He and his team did just that. The IRS wanted me to pay 250,000 dollars and they had no reservations about trying to get it. Like I said, I was polarized and I surely didn't have a quarter-million dollars and an agent had already been to my house without hesitation. Well, fast forward it's a year later and with the help and professionalism of Omid and his tax colleague Tyler I was freed from paying anything. That's right they resolved my IRS tax issue and even though they wanted 250 k, Omid stopped the Feds from seeking to get anything from me or my wife. I feel blessed to have met Omid and the K & S Law Group. Lifesavers!

Exactly what you expect from a professional
As a young business owner, I was clueless about the whereabouts of business formation and the tax implications of owning a company. When I realized how much structure it required I panicked. Mr. Shirazi stepped in, corrected my mistakes, created a strong structure for the business with elaborated internal controls and a good tax plan. It was a lot of work for the both of us and absolutely worth it.

Omid helped me negotiate a settlement deal with the IRS when they were claiming I owed over $60K in back taxes. I was hesitant to hire him at first. Franky speaking, he looked young. I decided to give him a shot after looking at his work experience with the IRS and as a CPA. He also came off as being genuine and honest. Qualities that I think many lawyers lack. His accounting and law experience helped me during the IRS settlement conferences to get a favorable offer. He knew how the IRS operated. After this whole ordeal was resolved, he explained why the IRS flagged my business. He then helped me with my accounting and taxes to avoid this type of scenario in the future.
