How the tax works
Texas does not levy a personal income tax on wages.
California taxes value as wages at graduated rates.
Federal income tax and payroll taxes are identical across the two.
California sourcing can reach equity earned while you were in California, even after a move.
What to check on your end
- That federal and payroll taxes match in the comparison.
- California's for the state-side difference.
- Which vests were earned during your California period.
- Whether a part-year California return applies after a move.
- California guidance or a professional for sourcing.
