Who We Serve

Silicon Valley Tax is a San Jose CPA and IRS Enrolled Agent firm built around the specific tax situations that Bay Area earners actually face. Below are the personas, situations, and locations we have dedicated practice pages for. If your situation fits one of them, the page goes deep on the math, the deadlines, and the planning levers that matter most for that audience. If you do not see your exact situation, our full-service practice covers the rest.

Equity compensation — the core of what we do

Most of our clients hold meaningful equity in a Bay Area tech employer, a startup they founded, or a portfolio of crypto positions. Equity tax is where the dollar amounts get large and the deadlines get unforgiving. Our practice pages cover the full lifecycle from pre-IPO planning through post-IPO diversification.

• Tax accountant for Bay Area tech employees — W-2 tech workers juggling RSU vests with 22% under-withholding, ISO exercises with AMT exposure, ESPP qualifying-disposition timing, mega-backdoor Roth contributions, and multi-state remote-work sourcing.
• Tax accountant for startup founders — Founders with restricted founder stock, the 30-day Section 83(b) window, Section 1202 QSBS planning (including the California non-conformity gotcha), entity structuring (LLC vs C-corp, Delaware vs California), and R&D credit eligibility.
• Pre-IPO tax planning — ISO exercise timing modeled against AMT, QSBS holding-period strategy, tender-offer tax treatment, and the multi-year exercise plans that avoid the IPO-day AMT trap.
• Post-IPO tax strategy — Lockup-expiry diversification, 10b5-1 plan timing, concentrated-stock unwind, tax-loss harvesting, charitable strategies via donor-advised funds and appreciated stock, and state-residency planning.
• California RSU tax planning — The 22% federal withholding gap on RSU vests, sell-to-cover vs hold decisions, California supplemental rate vs marginal rate, multi-state sourcing rules, and stacking RSU income with ISO exercises in the same year.
• Crypto tax accountant Bay Area — Multi-wallet basis reconciliation, staking and DeFi taxation, NFT mint vs purchase vs sale, FBAR for offshore exchanges, and IRS Form 1040 digital-asset reporting.

Local practices — by Bay Area city

We work with clients across the entire Bay Area, but our local pages reflect the specific employer concentrations and tax issues that come up most in each city. Each page calls out the local employer angle and the related blog posts most useful for that area.

What you get on every engagement

Every Silicon Valley Tax engagement starts with a free 30-minute consultation, includes a flat-fee quote before any work begins, and produces a written plan you can act on. We do not bill hourly. We do not surprise you on the invoice. We schedule the conversation that matters most (RSU vest timing, ISO exercise window, QSBS clock check) before the deadline runs out, not after.

Whichever practice page above matches your situation, the path is the same: book a free consultation, bring your most recent return, your equity grant documents, and your 401(k) plan summary, and we will model your specific situation in the first session.
