California Tax on RSUs and Stock Options After You Move
Understand California sourcing for RSUs and stock options when you move, work in multiple states, exercise options, or sell shares as a nonresident.
Direct answer
Moving out of California before selling shares does not automatically remove every California tax issue. Capital gain from stock held as an investment is generally analyzed differently from compensation earned for services. RSU and option income may remain partly California-source when services during the relevant grant-to-vest or grant-to-exercise period were performed in California.
The decisions to put on one timeline
Establish residency dates
Document when domicile changed and distinguish residency from temporary travel or remote work.
Map service days
Identify where services were performed during the sourcing period applicable to each award and lot.
Separate compensation and gain
Distinguish wage or AMT adjustments from later capital gain, which may follow different sourcing rules.
Coordinate state filings
Review withholding, nonresident returns, credits for taxes paid to another state, and consistent reporting across jurisdictions.
The sale state is not the only fact
An employee receives NSOs while working in California, later moves to Texas, and then exercises. California may source part of the exercise compensation to services performed in California even though the employee is a nonresident on the exercise date.

Frequently asked questions
If I live in Texas when I sell, is the stock sale free of California tax?
A nonresident's investment capital gain may not be California-source, but compensation embedded in an equity award can require a separate sourcing analysis. The answer depends on award type, service period, residency, and transaction sequence.
Does California tax ISO exercises after a move?
California guidance includes specific rules for ISO AMT adjustments and later dispositions when residency changes. The result requires award dates, service days, exercise details, and sale information.
What records should I keep?
Keep grant and vest schedules, exercise confirmations, payroll records, Forms 3921 or 3922, travel or work-location records, residency evidence, brokerage statements, and prior state returns.
