Any nonresident with income (winnings) from Louisiana sources who is required to file a federal individual income tax return must file a Louisiana return reporting income earned. If the amount withheld is overpaid, a refund of the difference will be issued or credited. You must file Form IT-540B, Nonresident and Part-year Resident Return, to report your winnings and withholdings to Louisiana. To obtain a copy of the return, visit LDR’s Forms page. You can also file electronically using LaTAP.
