If you earn a senior W-2 + RSU in San Jose, Cupertino, Santa Clara, or anywhere in the South Bay, your combined federal + state bracket runs ~50.3% (federal 37% + NIIT 3.8% + CA 13.3%). South Bay’s profile is older + more senior + more semiconductor-and-networking-heavy than Palo Alto’s startup-adjacent demographic — and the cost-seg strategy aligns differently as a result.
- $202,000 Accelerated Depreciation (typical premium STR worked example)
- $102,000 Est. Year-1 Tax Savings (federal + NIIT + CA)
- 128x Return on Study Cost

The South Bay investor profile
San Jose’s cost-seg buyer pool is older, more senior, more semiconductor + networking than Palo Alto’s startup-equity demographic:
- Senior FAANG + Apple Cupertino (Senior Principal, Distinguished Engineer, Director-level engineering at Apple Park, Google Mountain View, Meta) — $500K–$3M+ base + RSU
- Networking + semiconductor seniors (Cisco, NVIDIA, AMD, Broadcom, Marvell, Arista, Juniper) — $400K–$2M+ base + RSU
- Big-tech IPO alumni and post-IPO senior employees (10+ years tenure at Adobe, Cisco, Symantec, eBay) — $400K–$1.5M + accumulated equity
- Tech executives turned VC / angel investors — variable comp, often K-1 from advisory + LP positions
The combined marginal-rate stack:
- Federal: 37%
- NIIT: 3.8%
- California: 13.3% (top rate)
- Combined: ~50.3% at the top
San Jose’s typical investor is older than Palo Alto’s — late 30s to mid 50s, often with kids, often with significant accumulated RSU wealth from a 10+ year tech career. The cost-seg strategy here is less about pre-IPO equity timing (Palo Alto’s edge) and more about deploying accumulated post-IPO RSU into yield-generating STR property that produces Year-1 tax deductions to offset ongoing high-bracket income.
Verify with your CPA — combined-rate math depends on filing status, AGI thresholds for NIIT, and the property’s placed-in-service date for current CA-federal conformity treatment.
Why cost seg pays more if you live in the South Bay
A typical $800K–$1.5M out-of-state STR reclassifies 24–32% of basis under permanent 100% bonus depreciation. At South Bay’s combined bracket (~50.3%), every $1 of accelerated depreciation is worth ~$0.503 in Year-1 cash savings.
For a senior FAANG or networking-tech investor with $1M+ annual W-2 + RSU income, a $200K accelerated-depreciation deduction in Year 1 generates ~$100K in combined federal + state savings. That’s enough to fully offset the federal+state tax impact on $200K of W-2/RSU income — a significant Year-1 cash reduction that compounds across multiple properties.
Where South Bay investors are buying
South Bay investors flow capital to STR markets within a 3-5 hour drive or short flight:
- Lake Tahoe — Closest premium mountain/lake STR, 4-hour drive; CA combined bracket applies but premium ADR offsets.
- Park City, UT — Premium ski STR, UT 4.85% flat state tax adds modest savings.
- Maui, HI — Premium Pacific STR; direct flight from SJC.
- Sedona, AZ — Premium spiritual/wellness STR; AZ no state tax stack.
- Joshua Tree, CA — Design-driven desert STR.
The South Bay → Tahoe pipeline is most visible — Tahoe’s premium ADR + drivable access + senior FAANG investor profile aligns. Many South Bay investors also build a 2-3 property STR portfolio (Tahoe + Park City + Maui, for example) for diversification.
A real San Jose investor’s worked example
An Apple Senior Engineering Manager earning $625K base + $400K RSU + $150K bonus, residing in Cupertino, buys a 4BR Park City ski-in cabin for $950K with $35K immediate FF&E. After $230K in land, the $720K adjusted basis includes $86K in 5-year assets (hot tub, ski-storage equipment, smart-home, theater, kitchen package, decorative lighting), $32K in 7-year assets (custom furniture, themed bunk rooms), and $84K in 15-year property (mountain-grade deck, retaining walls, snow-drainage drive, fencing).
That’s $202K reclassified into accelerated depreciation in Year 1. At the CA combined bracket (~50.3%), federal + state savings come to roughly $102,000. The deduction fully offsets the federal + state tax impact on $200K+ of vesting-year income.
What disqualifies a South Bay investor
REPS is structurally impossible for a full-time senior tech professional — the 750-hour + >50% test conflicts with engineering and management hours. the STR exception (Reg. §1.469-1T(e)(3)(ii), 7-day average stay + 100-hour material participation) is the alternative path.
The 100-hour material participation test means active management. For a South Bay investor with multiple STR properties, the time investment scales — managing 3 properties remotely can exceed 100 hours easily. A senior tech investor with a portfolio of 2-3 STR properties is typically well within the Reg. §1.469-1T(e)(3)(ii) safe harbor.
Frequently Asked Questions
How is San Jose different from Palo Alto for cost-seg purposes? Tax-wise, identical — both pay CA’s 13.3% top rate. Where they differ: San Jose skews older + more senior + accumulated post-IPO equity; Palo Alto skews younger + pre-IPO equity + RSU vesting cliffs. The South Bay’s portfolio-building strategy (multi-property STR investing) is more common than Palo Alto’s vesting-timing strategy.
Can I cost-seg multiple properties in the same tax year? Yes. Each property generates its own Year-1 accelerated depreciation deduction. For a senior FAANG investor with $1M+ annual income, deploying 2-3 STR properties in a single calendar year can stack the deductions for a substantial combined offset. Talk to your CPA about how the deductions interact with passive-activity loss limitations.
Does California really conform to federal bonus depreciation? For property placed in service after January 19, 2025, yes — under OBBBA §168(k). Pre-2025 properties had different state schedules. Confirm with your CPA which schedule applies to your specific placed-in-service date.
