Georgia Other State Tax Credit Improperly Applied

[aecasas]

I am trying to file my return, but I am getting told I owe Georgia state tax when the Other State Tax Credit should make my state tax = 0$. I paid more in out of state tax than the tax I would have had to pay in Georgia so I should pay 0 in Georgia State tax with the other state tax credit, but it is not being properly calculated. How do I fix this issue? 

I am currently in Spain so I can not call the support number and use the free version so live chat is not an option.

The credit for taxes paid to another jurisdiction does not always cancel out tax- if your resident state has a higher tax rate you have to pay the difference.  Add your nonresident state to this string and someone may be able to check if there is a rate difference.

The two other states are Michigan and Illinois, but Georgia has a standard deduction of $12,000 so I effectively owe 5.39% on a very small portion of my total income and I paid far more in other state tax than that small portion.

The Georgia rate is 5.39%, the Illinois rate is 4.95%, the Michigan rate is 4.25%.  The tax credit applies to the comparable income, regardless of the state exemption amount (The exemption reduces the amount of income taxed, but the 5.39% applies to the taxable income. @aecasas
