Schedule 15-Min Safe Harbor Review

California Supplemental Tax Regulations for Google (Alphabet) RSUs

California Franchise Tax Board (FTB) mandates a 10.23% flat supplemental withholding rate for equity compensation. Because California top marginal rates reach 13.3% (plus 1.1% uncapped CASDI for wage bases), high earners frequently face a substantial 3.0%–4.0% state tax gap on April 15.

California Safe Harbor & Underpayment Penalties

Pay 110% of prior year CA tax or 90% of current year liability to eliminate underpayment penalties.

Employer Stock Plan Specifics: Charles Schwab / Morgan Stanley

Google utilizes a frontloaded monthly vesting schedule (33% across years 1 and 2). Because monthly vests are treated as supplemental wage distributions, Schwab withholds federal tax at flat 22%. Googlers with total comp above $350k find that each monthly tranche underwithholds by 10% to 15%, compounding silently over 12 months.

When vesting at Google (Alphabet), Charles Schwab / Morgan Stanley calculates automatic sell-to-cover withholding using California's statutory supplemental rate of 10.23% combined with the federal supplemental rate (22% on up to $1M). Because top earners in California reach marginal brackets exceeding these rates, you will face an incremental shortfall on April 15.
