The credit is calculated as your non-Ohio income divided by Total adjusted Income multiplied by the total tax. TurboTax (TT) does this by allocating your income as either Ohio or non-Ohio. W-2 income will be allocated by the state name abbreviation shown in box 15 of your W-2. TT will ask you, item by item, in the state section, how much of your other income is Ohio or non-Ohio income. Make sure that your FL wages show FL (Other state postal abbreviation) in box 15 of your W-2 screen, with the FL amount in box 16.
This system allows Ohio to apply their highest tax rate, based on your total income, while only taxing your Ohio income.
Ohio has a nonresident credit allocation form.. IT NRC
