  • Electronic Filing:
    Louisiana accepts Resident, Nonresident, and Part-year returns electronically. They can be transmitted with the Federal return or transmitted as a State only return. The electronic filing mandate is the requirement for certain tax preparers to file individual income tax returns electronically beginning January 17, 2012. The mandate applies to any tax preparer that prepares more than 100 Louisiana individual income tax returns during any calendar year. If the tax preparer is filing a Louisiana state only return or a Louisiana state amended return for a taxpayer, the tax preparer must maintain the LA FormR-8453, for three years from the return due date or the Department of Revenue received date, whichever is later. The state copies of the Forms W-2, W-2G, 1099R, and all supporting documentation required for state return line items should also be maintained.
