Today's Monday Map focuses on the deduction of state and local income or sales taxes from federal taxable income. New York State benefits the most from this deduction – its residents deducted an average of 6.16% of their income in state taxes. Alaska benefits least, having neither an income tax nor a statewide sales tax; the small average of 0.26% most likely comes from local sales taxes. Click on the map to enlarge it.
