Bespoke CPA Advisory for Foster City’s Biotech & Executive Profile
Foster City occupies a central waterfront position on the San Mateo County Peninsula, world-renowned as the corporate headquarters of biopharmaceutical giant Gilead Sciences alongside major financial tech and enterprise software campuses. Managing high W-2 salaries, executive stock options, vesting RSUs, and waterfront commercial or residential real estate requires a proactive, multi-year tax plan.
From converting sole proprietorships and LLCs via our LLC to S-Corp tax conversion hub and deploying the California AB 150 PTE tax election to overriding brokerage $0 basis reporting errors on Form 1099-B, we help Foster City taxpayers preserve their wealth. We serve founders, biotech researchers, and executives across Foster City, South San Francisco, San Mateo, and Burlingame using targeted RSU cost basis adjustments, ISO AMT tax modeling, and ESPP disposition strategies.
The Foster City Biotech Director Equity & Property Strategy
- The Event: A Biotech Director in Foster City liquidates $320,000 in vested equity/RSUs while generating $220,000 in consulting/S-Corp income.
- The Tax Drag: Pushed into top federal 35%–37% brackets and California’s 11.3%+ rate, while facing brokerage $0 basis reporting on Form 1099-B and the $10,000 SALT cap.
- Moontree CPA Fix: We file IRS Form 8949 (Code B/O) to adjust the cost basis to fair market value at vest (saving ~$64,000+ in phantom capital gains taxes) and execute the CA AB 150 PTE election for the entity.
- The Real Estate Shelter: We pair active corporate earnings with an engineering-based cost segregation study on Peninsula rental property to generate substantial paper tax write-offs.

Frequently Asked Questions for Foster City Taxpayers
How is the City of Foster City Business License Tax calculated for local enterprises and consultants?
Under City of Foster City Municipal Code Title 5, any business, S-Corporation, 1099 contractor, or home-based business operating within city limits must maintain an active City Business License. The tax is renewed annually and is generally calculated based on gross receipts generated within city limits or total employee headcount.
How does the California AB 150 PTE election help Foster City business owners bypass the SALT cap?
By electing into California’s Pass-Through Entity (PTE) tax workaround, eligible Foster City S-Corporation and partnership owners pay an elective 9.3% state tax directly at the business entity level. This transforms state tax payments into an above-the-line federal business deduction, completely bypassing the personal $10,000 SALT limit.
Why do stock brokerages report $0 cost basis on equity sales for Foster City biotech employees?
Federal tax rules prohibit custodians from automatically adjusting cost basis on Form 1099-B for non-statutory equity awards. Brokerages report gross sale proceeds and leave basis blank or at $0. We pull your Supplemental Statements to manually adjust your cost basis to fair market value at vest on IRS Form 8949 to prevent double taxation on W-2 equity.
