Typical comp shape
Technical program manager (TPM)s usually earn rsu + refresh grants. Common employers include Amazon, Microsoft, Alphabet. Amazon TPMs face the 5/15/20/60 back-loaded vesting schedule, which creates a massive year-four tax event without planning.
What California changes
In California, every RSU vest, NSO exercise, and ESPP purchase carries 13.3% state tax on top of federal. For a senior technical program manager (tpm) with $300k+ of equity income, the state layer routinely adds $25-45k to the annual bill.
State AMT for ISO holders
If your technical program manager (tpm) role grants ISOs (common at pre-IPO startups, uncommon at post-IPO mega-caps), be aware that California runs its own AMT calculation. An ISO exercise-and-hold here generates AMT at two layers, not one.
Planning cadence
For a technical program manager (tpm) in California, the three planning windows are: after each RSU vest (withholding check and sell-vs-hold), before any ISO exercise (AMT model at both federal and state), and in Q4 (estimated tax top-up to clear the safe harbor).
