California has one of the highest concentrations of tech workers, startup founders, and investors in the world—and the tax issues that arise from that environment are unlike those faced by most taxpayers. If you work in the California tech industry and receive compensation that includes equity, or if you are a founder navigating the tax implications of raising capital or selling a company, finding a tax professional with specific tech-industry experience is a worthwhile investment.
Common Tax Issues for California Tech Workers
- RSU taxation at vesting: RSUs are taxed as ordinary income when they vest. Many tech employees are surprised by the tax bill in the year of vesting, particularly when a company goes public or has a high stock price. A professional can help you model your estimated tax liability and adjust withholding or estimated payments accordingly.
- ISO exercise timing: Exercising incentive stock options early in the year—before the stock price rises further—is a strategy some employees use to manage AMT exposure. This requires careful modeling of both federal AMT and California income tax, which does not have a separate AMT but taxes the ISO spread differently.
- 83(b) elections for founders: Founders who receive restricted stock (not RSUs) can make an 83(b) election within 30 days of receiving the shares to lock in a low tax basis. This election must be filed with the IRS within 30 days—there are no extensions. A professional who handles this regularly can ensure it is done correctly.
- Qualified Small Business Stock (QSBS): Section 1202 of the Internal Revenue Code provides a potential federal capital gains exclusion on gains from the sale of qualified small business stock. California does not conform to this exclusion—California taxes the full gain. This nonconformity surprises many founders who assumed the federal exclusion applied to their state taxes.
Finding a Tax Professional With Tech-Industry Experience
Firms that specialize in serving technology employees and founders are concentrated in the San Francisco Bay Area and Los Angeles, though many now work with remote clients throughout California. When evaluating candidates, ask about their experience with 83(b) elections, ISO/AMT planning, and California’s nonconformity with QSBS exclusions. Ask whether they have worked with employees at pre-IPO companies and whether they can model multiple scenarios before you take a major equity action.
Timing Is Critical
Many equity-related decisions—83(b) elections, ISO exercises, charitable donations of appreciated stock—are time-sensitive. The best time to find a tax professional with tech-industry expertise is before you need to make a decision, not after. A professional engaged before a major liquidity event has time to plan; one engaged after can only document what has already happened.
