State Income Tax
In plain English
A state or local tax on taxable income whose brackets, deductions, credits, and rates vary by jurisdiction and filing status.
State income tax is imposed by a state or locality on taxable income. Brackets, standard deductions, credits, reciprocity, and local taxes vary, so an effective-rate calculator is a planning shortcut—not a state return.
