Career

There’s a reason you haven’t heard of Jon’s toughest cases. During his years as a senior IRS trial attorney, Jon gained a unique understanding of IRS perspectives and procedures. He speaks their language and knows how to work within the system to deescalate or get the IRS to walk away. The IRS team knows Jon to be as knowledgeable as he is fierce, and skilled at every stage of a tax dispute, including Examination, Appeals and litigation. This extraordinary combination has enabled Jon to quickly and quietly resolve hundreds of complex, high-stakes tax matters before the IRS, as well as the California Franchise Tax Board (FTB) and other state agencies.

Moreover, as someone who represents individuals and public companies, Jon’s clients receive the best of both worlds: a hands-on and personalized approach, along with incredibly sophisticated counsel. He helps clients of both types navigate challenging tax environments involving income, estate and gift, employment and international tax issues. He also utilizes his first-hand knowledge of the IRS to help clients comply with new tax rules and correct previous mistakes. When proactive compliance measures are not possible, Jon litigates international and domestic tax controversies before the U.S. District Court, U.S. Tax Court and California Superior Court.
