Devon J. Arabo, ESQ., LL.M.

Devon Arabo - RJS LAWDevon J. Arabo

Of Counsel & Co-Chief of Operations

Email:  darabo@rjslawfirm.com

Devon J. Arabo is Of Counsel & Co-Chief of Operations at our firm, where he has worked for over 16 years. In his expanded role, Mr. Arabo also serves as Chief of Legal Operations at RJS LAW. Mr. Arabo represents clients before the Internal Revenue Service (IRS), Franchise Tax Board (FTB), Employment Development Department (EDD), and California Department of Tax and Fee Administration (CDTFA).

Mr. Arabo represents clients facing tax-related issues before various state and federal taxing authorities. His thoughtful strategy and compassionate advocacy have saved his clients millions of dollars and earned them priceless peace of mind. Over the course of his career, Mr. Arabo has handled an exceptionally broad range of tax controversy matters, from routine examinations to high-stakes audits, consistently delivering results that reflect both his technical mastery and his fierce dedication to his clients.

Mr. Arabo’s audit results speak for themselves. He has achieved numerous no-change audit determinations, meaning the IRS or state agency accepted the taxpayer’s return as filed and assessed no additional tax, as well as favorable audit results where proposed adjustments were significantly reduced through skilled negotiation and advocacy. Notably, he recently saved a client over $1 million in one such complex IRS audit, where an initial proposed liability of more than $1.7 million was ultimately settled for just $450,000.

Mr. Arabo has developed particular expertise in complex IRS audits involving multiple entities. These multi-entity matters demand not only deep knowledge of tax law but also the ability to manage voluminous records, coordinate across business interests, and craft a cohesive, strategic defense, all skills Mr. Arabo has demonstrated time and again.

Among the most sensitive matters in Mr. Arabo’s practice are “eggshell audits,” or high-stakes civil audits where underlying facts could potentially give rise to criminal tax exposure. Navigating an eggshell audit requires a practitioner who understands both the civil and criminal dimensions of tax law, and who can walk that razor’s edge with precision and composure. Mr. Arabo has successfully guided clients through multiple eggshell audits, resolving each matter at the civil level and avoiding any additional criminal exposure, outcomes that represent not just financial relief, but the protection of his clients’ freedom and reputations.

He has also settled successful Offers in Compromise for pennies on the dollar, allowing clients burdened by overwhelming tax debt to resolve their liabilities for a fraction of what was owed and move forward with a clean slate. In addition, Mr. Arabo has secured penalty abatements totaling millions of dollars across a range of clients, demonstrating his ability to effectively argue reasonable cause and other relief provisions before the IRS and state agencies. His work extends to EDD misclassification audits as well, where he has protected businesses from crippling reclassification assessments by building airtight factual and legal records in support of independent contractor status.

What sets Mr. Arabo apart is not only his legal acumen but his tenacity and the strong professional relationships he has cultivated with IRS revenue agents, revenue officers, and state agency personnel over his years of practice. He approaches every matter with relentless preparation and an unwillingness to accept an unjust result, while maintaining the credibility and mutual respect with government representatives that is essential to resolving complex matters efficiently. Clients routinely describe Mr. Arabo as a tireless advocate who fights hard for them while always keeping their long-term interests at the forefront.

Mr. Arabo’s commitment to excellence and client advocacy has earned him a stellar reputation throughout the community. He is a member of the San Diego County Bar Association and regularly presents to Enrolled Agents and CPAs at the California Society of Tax Consultants, sharing his expertise in tax controversy and resolution strategies. Beyond his legal practice, Mr. Arabo is also an active real estate investor. He began honing his business acumen while providing administrative assistance to Shamoun Investments Co., where he facilitated multimillion-dollar transactions, including significant property acquisitions and sales.

Mr. Arabo is a proud “Triple Torero,” having graduated from the University of San Diego with three degrees. Mr. Arabo earned his Bachelor of Accountancy with a minor in both Finance and Real Estate. As part of his undergraduate experience, Mr. Arabo was an involved member of USD’s Accounting Society.

Mr. Arabo also earned his Juris Doctor (JD) from the University of San Diego School of Law. During law school, Mr. Arabo was a member of the Tax Law Society and Middle Eastern Law Student Association. In his second year of law school, Mr. Arabo served as the American Bar Association (ABA) Chair where he assisted students with registering with the ABA, which is the largest professional organization for practicing attorneys. After graduating law school, Mr. Arabo continued his educational journey by obtaining his Master of Laws in Taxation (LL.M) from the University of San Diego School of Law.

Mr. Arabo’s professional excellence has been widely recognized. He was named one of San Diego’s Top Attorneys in 2023 and in 2026; selected for SD Metro Magazine’s 40 Under 40 in 2023, 2024, 2025, and 2026; and honored as a 2025 and 2026 Super Lawyers Rising Star, a designation reserved for attorneys who exhibit excellence in practice, based on peer recognition and professional achievement.

Born and raised in San Diego, Devon is a die-hard Padres fan and an active member of his community. Off the clock, he enjoys spending quality time with his wife Chanel and his son Damon.

Testimonials

Compassionate. Knowledgeable. Capable. The team at RJS, specifically Brad, Marisol and Ronnie were on top of all of our issues. They were efficient and communicated with us on every step. Finding a team that is on top of their game like RJS is a tough find.... add to that the compassion and care they provide makes them second to none. Call them now. - Mike G.
RJS Law firm was very professional and someone was always available to answer our questions. They really looked out for our interest only! If you want the best Law Firm Representing YOU, These guys are absolutely SECOND TO NONE!!! I  highly recommend them! Thank you for solving my tax problems! You guys Rock! - Mike S.
Amazing!  In today's world of NO customer service and only internal focus, The RJS Law firm and Chandara in particular completely changed my perspective.   Due to a complicated personal situation, I found myself  in a difficult position with the IRS.  One call and I can not tell you how relieved I am.  I can breathe again, and what is even more amazing-  I do not need an attorney.  Chandara advised me on how to resolve this myself.  It would have been easy to just take my money and add further stress to the situation,  but she didn't. I believe that nothing but good can come from true acts of kindness, so I truly thank her and RJS for outstanding service and should I ever need an attorney-  she will be my first call. - Michele W.
Calling this firm put me at ease. I had sleepless nights as I was procrastinating to take care of my problems; I didn’t know how to go about them. Seeking legal help is always a good way to go, as they are more suited for the job. Chandara has guided me through the process of my stressful situation. No strings attached but I couldn’t let go, I truly recommend them. They will give you sincere and honest answers at all times. I couldn’t be more at ease with my family taking this a step at a time. - Kimberly
I have been a tax client of RJS Law for nearly 10 years. Mr. Shamoun and his team have always delivered results above and beyond my expectations. My attorney has always been just a phone call away when I need advice. I would highly recommend RJS Law to anyone in need of representation for tax related matters! - Brad
My grandmother and I called RJS LAW because she fell behind on her business taxes. She no longer owns the business so she wanted to get back on track and settle that debt. Brendan was very informative and very helpful. We set up a consultation and everyone at the firm was very polite. Brendan helped us create a plan so that we can get resolution to the problem. He helped turn this insurmountable issue into something manageable going forward. I highly recommend this place! - Deana
With no doubt I have to say I have the best advice going forward. I was in the military residing from California but I was stationed in Texas and I didn’t know my filing requirements. Not only I got my questions answered by they gave me free knowledge that I wouldn’t ever had known. I feel comfortable with filing now and going forward I will know what’s best for me. The best thing I liked about this firm is that they answered right away! Transferred my call to an attorney and got it done! In no time! Highly professional and helpful! - Karla
We worked with Brad Paladini on an appeal for an Offer in Compromise we previously submitted on our own. Looking back we should have hired RJS BEFORE we tried submitting an OIC on our own. Brad was amazing to work with on the OIC appeal and literally saved us over $100,000 in taxes. Didn’t show any judgement, took over all the IRS communications and helped us get all the paperwork the IRS was requesting. He fought for us like a bulldog to win the appeal. We are so thankful we found RJS LAW through Yelp and decided to write a review to pay it forward! - Holly
RJS LAW San Diego came to us highly recommended. The firm delivers with precision, tact and professionalism. They are not cheap, but cheap doesn’t always deliver. Ronnie Shamoun, Quinn Disparte, and their associates treated our case with respect, dignity, empathy and speed. They were able to get our case dismissed timely, as promised and without any of the associated headaches that normally come with the territory. The end result was tremendous peace of mind. If that is what your ultimate goal is you need not look any further. - Mandana
