Is Property tax deductible on WI state income tax?
Should property tax (which is a local tax) be deducted when you calculate AGI for state income tax? Otherwise, I pay state tax on money I use to pay for another local tax. For example, suppose my adjusted gross income (after all other adjustments) is $100k. Property tax is $10k. Should state tax be assessed on $100k-$10k=$90k?
