Silicon Valley CPA Tax Advisory & Equity Accounting

Silicon Valley Tax Planning Built Around Your Financial Picture

The Silicon Valley core—spanning from San Jose and Campbell up through Cupertino, Sunnyvale, Mountain View, and Palo Alto—represents the densest concentration of technology wealth in the world. Navigating the tax code here requires specialized knowledge of employer-specific equity structures (like Apple RSUs or Alphabet GSUs), high-bracket entity taxation, and complex real estate acquisitions.

Moontree Tax approaches South Bay wealth as an integrated ecosystem. We do not just file your 1040. We align your Form 8949 equity basis adjustments with your S-Corporation tax strategies and your real estate depreciation schedules, building a unified firewall around your active and passive income.

The Moontree Silicon Valley Wealth Integration Matrix (Case Study)

• The Event: A Sunnyvale-based Director of Engineering liquidates $600,000 in highly appreciated tech RSUs while simultaneously generating $250,000 in 1099 consulting income through a side business.
• The Tax Threat: They are immediately pushed into the 37% federal and 12.3% California brackets. Without intervention, they face a 15.3% self-employment tax on the consulting income, a $0 cost-basis reporting error on their 1099-B from their brokerage, and are capped at the $10,000 SALT deduction limit.
• The Framework Execution: We execute our Wealth Integration Matrix. First, we file an 8949 cost-basis adjustment to eliminate double taxation on the RSUs. Next, we convert the consulting LLC to an S-Corp and file the California AB 150 PTE election. Finally, the client uses the equity proceeds to acquire a San Jose multi-family property, allowing us to deploy a cost segregation study.
• The Result: The basis correction saves over $80,000 in phantom capital gains tax. The S-Corp structure legally bypasses the SALT cap and eliminates self-employment tax drag, while the real estate paper losses shelter the remaining high-bracket income.
