You have to include all your income.
Ohio does a convoluted tax calculation for non-residents/part year
residents. It calculates tax on total income, then it calculates a non
resident/part year resident credit, which it subtracts from the tax it
calculated on the total income. 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 non-Ohio wages show IN (Other state postal abbreviation) in box 15 of your W-2 screen, with the IN amount
in box 16.
If OH shows in box 15 of your W-2, be advised that you may have to use a work around to get TT to prepare the return to get you your
refund. At the w-2 screen split the boxes 15-20 W-2 info into 2 lines. On the
1st line leave OH in box 15 but
make box 16 blank;
leave the OH withholding in box 17.
On the 2nd line put your home state abbreviation in box 15 and the state wages
amount in box 16;
leave box 17 blank..
