We have automatically carried over your itemized deductions from your federal return to your California return. However, you may need to make manually adjustments to the following:
State and Local Taxes
California does not allow a deduction for state and local income tax (including limited partnership tax and income or franchise tax paid by corporations) and State Disability Insurance (SDI) or state and local general sales tax.
California does not permit a deduction for foreign income taxes.
Home Mortgage Interest
Federal changes limited the mortgage interest deduction debt maximum from $1,000,000 ($500,000 for married filing separately) to $750,000 ($375,000 for married filing separately). California does not conform with federal law. If your deduction was limited on the federal return enter an adjustment on itemized deductions for the amount over the federal limit.
Federal rules have suspended the deduction on up to $100,000 ($50,000 for married filing separately) for interest on home equity loans, unless the loan is used to buy, build, or improve the taxpayer’s home that secures the loan. California does not conform so if your deduction was limited enter an adjustment.
