Your rental income is taxable in both states. It is taxable in Georgia because that's where the property is. It is taxable in Alabama because you are a resident of that state. Although it is taxable by both states, your state of residence - Alabama will give you a credit for tax paid to Georgia so you won't be double taxed. If you have other income that shows on your Georgia Return then you need to revisit your Georgia return and only allocate the portion of your income that was from the rental to Georgia.
