About Boulanger CPA – California CDTFA Audit Defense, Led by a Licensed CPA

Our Mission

At Boulanger CPA and Consulting PC, our mission is simple: to defend California business owners from aggressive CDTFA, FTB, and EDD enforcement — with CPA-led strategy, clarity, and precision.

CDTFA audits can overwhelm even the most organized businesses. Our role is to bring order to the chaos, protect your rights, rebuild accurate records, and challenge inflated assessments so you’re not paying tax you do not owe. For a deeper overview of what these audits involve, see our CDTFA sales tax audit guide.

We exist to offer honest, responsive, and deeply specialized California tax defense — not call center tactics or generic accounting support.

Our Story

Boulanger CPA and Consulting PC was founded to provide high-level tax defense services without the bureaucracy, call-center tactics, or “bait-and-switch” model common in the tax resolution industry.

California enforcement requires deeper audit methodology knowledge, stronger documentation support, and strategic representation. That's why this firm was built — to serve business owners who value precision, responsiveness, and true CPA expertise. We regularly publish guidance on how the California sales tax audit process works and California tax enforcement more broadly.

Today, we represent clients throughout California, including restaurants, retailers, contractors, online sellers, automotive shops, and multi-location businesses facing CDTFA, FTB, or EDD inquiries. For examples of the types of businesses CDTFA often targets, see industries targeted by CDTFA sales tax audits.
