What the result means

The result shows how state deductions and adjustments reduce taxable income. It can be paired with a state tax rate to estimate savings.

State Taxable Income = Gross Income - State Standard Deduction - State Itemized Deduction - Other State Adjustments

State deduction systems vary. This calculator does not choose the correct deduction automatically.
