Real Client Case Study — San Diego, CA

Real Client Case Study — San Diego, CA

850kW − 2income,

Client: J. Chen — Biotech Executive

Financial Mix: 1.2M RSU vest from a major Sorrento Valley biotech firm, rental property in Del Mar, and K-1 income from a real estate syndication.

Problem: J. Chen’s previous accountant failed to properly plan for the RSU vest, resulting in a massive underpayment penalty and a $250,000 tax bill due in April. The rental property depreciation was also incorrectly calculated.

What We Did:
● Immediate Fix: Filed an amended return for the prior year, correctly allocating the RSU income and minimizing penalties.
● Proactive Strategy: Implemented a “sell-to-cover” strategy for future vests and set up quarterly estimated payments to align with the actual tax liability.
● Real Estate Optimization: Conducted a retrospective review of the Del Mar rental, correcting the depreciation schedule and utilizing passive activity losses to offset other income.
● Future Planning: Advised on a charitable giving strategy using appreciated stock to further reduce taxable income.

Result: $85,000 in annual tax savings and a complete elimination of underpayment penalties going forward.

This case study is typical of the high-stakes, complex financial situations we resolve for San Diego’s top professionals. The unique blend of high-value equity compensation and sophisticated real estate investment demands a Tax Advisor with a deep, specialized understanding of both.
