Project name

Som Sonenarong is a Tax Director in BPM’s Flow-Through group. He specializes in tax planning and compliance for privately held businesses and their owners, with a strong emphasis on partnership taxation. Based in BPM’s Santa Monica office, Som brings over a decade of experience in public accounting, including seven years at a mid-tier CPA firm where he focused on large business entities, flow-through structures, and international tax matters.

Som is dedicated to creating value for BPM clients by delivering tailored solutions to complex personal and business tax challenges. He regularly advises clients on the tax implications of various elections and helps them understand how these decisions impact both their business and personal financial outcomes.

In a recent engagement, Som reviewed a client’s C-Corporation tax returns for the current and prior open years, identifying a refund opportunity related to California’s throwback rules. Som identified and amended four years of returns to save the client $500k from overpaying state taxes.

Som approaches every engagement with a holistic mindset, always considering how a business’s activities affect its owners. His proactive and detail-oriented approach ensures clients receive insightful, forward-thinking tax guidance.

Somphone (Som) Sonenarong holds an active CPA license in California.
