Amended returns can be filed by re-filing a corrected tax period return with an X marked in the Amended Return box and attaching an explanation of the changes. The amended return should be mailed to the address on the tax return.
Amended individual income tax returns can be file electronically using the Louisiana File Online application. If you filed your original tax return electronically, you may log in to your account and amend your original return. If you filed your original tax return on paper or via another electronic filing option, you can still file your amended return electronically using the Louisiana File Online application. You must register and create a User ID and password and then select the amended tax return option.
Amended business tax returns can be filed electronically using the Louisiana Taxpayer Access Point (LaTAP) system. Once registered for the LaTAP system, you can file and pay your taxes electronically and review your tax filing and payment history for all taxes.
