We've recently highlighted a variety of progressive revenue raising options gaining serious attention in New York and Wisconsin. This week we bring you yet another idea that's recently been the subject of debate, though this one applies to fewer states. Those seven states still offering income tax deductions for federal taxes paid (i.e. Alabama, Iowa, Missouri, Montana, North Dakota, Louisiana, and Oregon), should immediately repeal, or at the very least dramatically scale back, that deduction.
The federal income tax deduction takes what is perhaps the best attribute of the federal income tax -- its progressivity -- and uses it to stifle that very attribute at the state level. Since wealthy taxpayers generally pay more in federal taxes than their less well-off counterparts, allowing taxpayers to deduct those taxes from their income for state income tax purposes is a gift to precisely those folks who need it least. And since most state income tax systems possess a degree of progressivity, those better-off taxpayers who face higher marginal tax rates are benefited even more by being able to shield their income from tax via this deduction.
Iowa Governor Chet Culver most recently drew attention to this problem while urging lawmakers this week to end the deduction. The idea has also recently garnered attention in Missouri, where ITEP recently testified on a bill that would, among other changes, eliminate the deduction. Finally, another bill making its way through the Alabama legislature seeks to end the deduction for upper-income Alabamians.
With three of the seven states that still offer this deduction considering its elimination, this is definitely one progressive policy change to keep an eye on.
