Question

What are California itemized deduction categories'for 2024?

Answer 1

California uses the same basic itemized-deduction categories as the federal Schedule A. For tax year 2024 the common California itemized deduction categories are:

- Medical and dental expenses
- Taxes you paid (state and local income taxes, real estate taxes, personal property taxes, etc., subject to state rules)
- Interest you paid (home mortgage interest, investment interest)
- Gifts to charity (cash and noncash)
- Casualty and theft losses (limited and generally for federally declared disasters)
- Gambling losses (to the extent of gambling winnings)
- Miscellaneous deductions / other itemized deductions (various other items that may be allowed under California law)

Note: California does not always conform to federal law on every deduction (some federal deductions are limited or suspended, others are added back for California). If you want, I can:
- show how those categories appear on California’s Schedule A / Schedule CA (Form 540), or
- list common California-specific differences from federal treatment (e.g., which miscellaneous deductions are allowed or disallowed), or
- help determine which deductions you personally can claim.
