I am a resident of CA and sold an investment property in Hawaii. Is there a specific form I need to file in Hawaii for my taxes or do I need to file a complete State Return for Hawaii, as I do for California?
If you are using TurboTax, you should most likely just purchase the Hawaii state return package and prepare that return before your California return.
Hawaii starts with federal adjusted gross income, so any profit or loss reported on your federal Schedule D, Capital Gains and Losses, will be included in federal AGI, and thus flow into your Hawaii Form N-15 non-resident income tax return.
You will have to separate Hawaii capital gains or losses from your federal total in the Hawaii section of TurboTax.
At the time of sale, you should have filled out Form N-288B for nonresident withholding from the sale. Include this form and attach a copy to your return.
