Yes, you must file the nonresident West Virginia (WV) tax return. They will know the sales price and not the cost basis of the property sold until the return is filed. The loss will not generate tax, but is still required to be filed.
You must file a West Virginia income tax return if: (WV Instructions)
• You were a resident of West Virginia for the entire taxable year
• You were a resident of West Virginia for a part of the taxable year (Part-Year Resident)
• You were not a resident of West Virginia at any time during 2023, but your federal adjusted gross income includes income from West Virginia sources (nonresident)
