Bespoke CPA Advisory for San Carlos’s Life Science & Enterprise Community
Affectionately known as “The City of Good Living,” San Carlos occupies a vital central Peninsula location that has evolved into a powerhouse for biotech innovation, advanced light manufacturing, and commercial trades, anchored by vibrant downtown dining along Laurel Street. High-earning software executives, life science directors, and business owners navigating complex stock vests and multi-tier tax obligations require a proactive, multi-year strategy.
From restructuring 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 San Carlos taxpayers preserve their wealth. We serve founders, principal scientists, and tech directors across San Carlos, Redwood City, San Mateo, and Belmont using targeted RSU cost basis adjustments, ISO AMT tax modeling, and ESPP disposition strategies.
The San Carlos Executive Equity & Real Estate Play
- The Event: A Biotech VP or Senior Tech Director in San Carlos liquidates $300,000 in vested tech/biotech equity while generating $230,000 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 ~$60,000+ 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 San Carlos Taxpayers
How is the City of San Carlos Business Registration Tax calculated for local enterprises and consultants?
Under City of San Carlos Municipal Code, any business, S-Corporation, 1099 contractor, or home office operating within city limits must maintain an active Business Registration. Annual registration taxes are assessed based on prior-year gross receipts generated in San Carlos (or flat annual tiers for professional classifications).
How can San Carlos S-Corporation and LLC owners bypass the federal $10,000 SALT cap?
By electing into California’s Pass-Through Entity (PTE) tax workaround under AB 150, eligible San Carlos 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 San Carlos tech 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.
