A Masterful Tax Attorney with Decades of Expertise

When our family trust became entangled in a complex capital gains issue following the sale of a long-held commercial property, we were referred to Jay Weill. From our first consultation, his 48 years of deep experience in tax law were immediately evident. He didn't just recite code; he explained the strategic landscape, outlining several pathways with clarity and patience. His recognition by Best Lawyers in Tax Law is well-deserved, reflecting a career-long mastery we felt firsthand. Jay and his team at Sideman & Bancroft meticulously prepared our case, navigating both state and federal implications with precision. The result was a favorable resolution that preserved a significant portion of the estate for future generations. Beyond his technical skill, Jay is a consummate professional—responsive, thoughtful, and genuinely invested in achieving the best outcome. For anyone in San Francisco facing sophisticated tax or general practice matters, I cannot recommend him more highly.
