CPA Firm in Milpitas, CA — Tax Planning & Advisory for Silicon Valley and the Bay Area

SG Inc CPA is a CPA firm located at 428 S Main Street, Milpitas, CA 95035, serving medical practice owners, real estate investors, and high-income business owners across Silicon Valley, San Jose, and the greater Bay Area. We provide proactive tax planning, accounting, bookkeeping, and year-round advisory services — in person at our Milpitas office and remotely throughout the region.

California is one of the most complex tax environments in the United States. A top marginal state income tax rate of 13.3 percent, an $800 annual LLC franchise tax, mandatory Franchise Tax Board (FTB) compliance, community property considerations, and the interaction between California and federal tax law create a planning surface that most CPAs treat as a compliance checklist. The business owners and professionals who pay the least in California taxes are the ones whose CPA treats it as a year-round strategy.

SG Inc CPA is built for exactly that. Led by Shweta Garg, CPA, CTC — a Certified Tax Coach — our Milpitas team coordinates your California and federal taxes, your entity structure, and your personal financial goals into a single, proactive plan. Whether you are a physician in Santa Clara County, a property investor in the South Bay, or a business owner with operations in both California and Texas, we bring everything into one coordinated picture.

Serving Silicon Valley and the Bay Area in person or remote.

The California Tax Reality Why Bay Area Clients Need a Planning-First CPA

California imposes one of the highest combined tax burdens on business owners and high-income earners in the United States. Filing accurately is not the same as filing strategically — and for Bay Area clients, the gap between the two is measured in tens of thousands of dollars annually.

CA State Income Tax

California’s top marginal income tax rate is 13.3% — the highest state income tax rate in the US. Combined with a 37% federal rate, Bay Area high earners can face a combined marginal rate exceeding 50% without proactive planning.

CA LLC Franchise Tax

Every California LLC pays a minimum $800 annual franchise tax, regardless of income. LLCs with gross receipts above $250,000 pay additional fees on a tiered schedule. Entity structure decisions in California carry a direct annual cost that must be factored into planning.

CA vs. Federal Conformity Gaps

California does not conform to all federal tax provisions — including the 20% pass-through deduction (Section 199A), bonus depreciation, and certain retirement contribution deductions. A Bay Area CPA must understand these non-conformity gaps explicitly, not assume federal and state returns mirror each other.

Multi-State Tax Exposure

California taxes all income of residents regardless of where it is earned. California business owners with out-of-state operations, investments, or properties face both CA FTB filing obligations and the complexity of allocating and apportioning income across states.

Prop 19 & Real Estate

California’s Proposition 19 (effective 2021) significantly changed property tax reassessment rules for transfers and inheritances, directly affecting Bay Area real estate planning. 1031 exchanges remain one of the most important tax deferral tools for California property investors.

EDD & Payroll Compliance

California’s Employment Development Department (EDD) imposes strict payroll tax requirements including CA SDI and SUI. S-Corp owners in California must carefully structure owner compensation to balance payroll tax efficiency against EDD audit risk.

Who We Serve in Silicon Valley and the Bay Area

01
Medical practice owners and physicians in Silicon Valley

Physicians, surgeons, dentists, and clinic owners across Santa Clara County — including those affiliated with or operating near Stanford Health Care, UCSF Health, Kaiser Permanente, and the independent practice networks in San Jose, Sunnyvale, and the South Bay. California healthcare operators face state payroll compliance, FTB audit risk, and personal income that often combines practice income, partnership distributions, and investment returns in ways that require coordinated planning across all three.

02
Real estate investors and property owners in the Bay Area

Bay Area landlords, residential and commercial investors, short-term rental operators, and multi-entity property businesses across Santa Clara, Alameda, and Contra Costa counties. California’s Prop 19, high property values, 1031 exchange planning, and the interaction between rental income and California’s passive activity rules make Bay Area real estate one of the most tax-complex investment classes in the country. Lender-ready bookkeeping and clean, property-level financials are especially important in a market where refinancing and acquisition timelines move quickly.

03
High-income business owners and S-Corp operators in the South Bay

Bay Area business owners with $500K or more in annual revenue — S-Corp owners, LLC operators, and multi-entity businesses — who face California’s high marginal rates on top of federal obligations. We also serve business owners with operations or income in both California and Texas, where the two-office structure of SG Inc CPA provides a single CPA relationship that understands both states’ tax requirements.

Silicon Valley, South Bay, and East Bay

SG Inc CPA’s Milpitas office serves clients throughout Silicon Valley and the broader Bay Area. In-person appointments are available at 428 S Main Street, Milpitas, CA 95035. Remote service is available to all clients throughout the region and across California.

Why Bay Area Clients Choose SG Inc CPA

Silicon Valley has no shortage of CPA firms. What distinguishes SG Inc CPA in the Bay Area market is a combination of credentials, industry specialisation, and a planning model that is genuinely different from the compliance-first approach that most local firms offer.

Led by a Certified Tax Coach (CTC) — a rare credential in the Bay Area

Deep California state tax expertise

California’s tax code diverges from federal law in ways that catch underprepared clients by surprise — Section 199A non-conformity, bonus depreciation disallowance, LLC franchise tax tiers, EDD audit exposure, and multi-state sourcing rules. SG Inc CPA treats California state tax planning as a core competency, not an afterthought.

Specialisation in Bay Area medical practices and real estate

Silicon Valley’s healthcare sector — from independent physician practices to multi-location specialty groups — and its real estate market present a level of financial complexity that general-practice CPAs are not well-positioned to handle. SG Inc CPA has built its practice around these two client types and the specific planning opportunities each creates.
