California RSU sourcing calculator.
Workdays-based allocation for RSUs vesting after a CA move.
California sources RSU income by the workdays-in-California ratio during the vest's earning period — even after you've left the state. Enter your workdays and vest value to see how much California-source income remains.
California RSU sourcing — workdays-based allocation
Enter your vest's earning period workdays. We'll calculate the California-source percentage. Nothing is sent or stored.
Important. California's RSU sourcing rule is complex. This tool applies the standard workdays-based allocation for a single vest tranche. Real-world allocations may need to handle: (a) multiple vests in the same year, (b) grant-date vs. vesting-date residency changes, (c) part-year California residency, (d) interaction with the federal income inclusion timing. We model these at intake. This calculator is for orientation, not a substitute for a prepared return.
