Marker for the full 10-bracket CA table (1%–12.3% + the 1% Mental Health Services Tax above $1M, folded into the marginal table). CORRECTED 2026-08-28: the original entry transcribed the TY2024 table ($10,756 first-bracket top) from a secondary source while labeled TY2025; the whole table was re-entered from FTB's official 2025 rate schedules (Schedules X and Y). FTB indexes brackets annually — re-enter from the new schedules every tax year.
