Tax planning tips for San Francisco

California's most important tax planning consideration for tech employees is stock compensation. California taxes RSU vesting and stock option exercises as ordinary income in the year of vesting or exercise — at combined federal + state rates that can reach 50%+ for high earners. Deferring RSU vesting where possible, or exercising ISOs (Incentive Stock Options) early when the spread is small, can significantly reduce the tax cost of equity compensation. The federal AMT interacts with ISO exercises in ways that can create large unexpected tax bills — if you hold ISOs, model the AMT impact before exercising. Maximising 401(k) contributions ($23,500 in 2025) reduces both federal and California taxable income simultaneously.

Common mistakes to avoid

The most common and most expensive mistake for San Francisco tech employees is not planning for RSU and option tax events. Many employees receive vesting notifications without understanding that each vest is a taxable event at ordinary income rates — and that their employer's standard withholding (often 22% federal) is well below their actual marginal rate (37% federal + 13.3% California). The result is a large tax bill in April that surprises employees who spent their vested RSU proceeds assuming the withholding covered the full liability. Working with a CPA who specialises in equity compensation is essential for anyone with significant unvested equity.
