Line 5a – 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. Enter that amount on line 5a, column B.
Line 5e – The federal deduction for state and local tax is limited to $10,000 ($5,000 for married filing separately) for the aggregate of state and local income taxes and property taxes. California does not conform. If your deduction was limited under federal law, enter an adjustment on line 5e, column C for the amount over the federal limit.
