Generally, you should use the same filing status that is used on the federal return.
If you are filing a joint federal return and one spouse is a full-year nonresident with no Georgia-source income, you may file a separate return claiming yourself only, or a joint return claiming total allowable deductions.
If one spouse is a resident and one is a part-year or nonresident, use the Nonresident or Part-year Resident status in File > Client Properties > Georgia and complete Schedule 3 on Screen NRPY, in the Income & Adjustments folder, to calculate Georgia taxable income.
