The Louisiana R-540X is for your records only and should not to be mailed to the Louisiana Department of Revenue. To amend the Louisiana return, you may either e-file a corrected IT-540 (or IT-540B), or paper file a revised IT-540 (or IT-540B). Form R-540X is only for use as a tool to help reconcile differences of the changes you make. Even though there is not a Non-Resident R-540X, you can still amend your Form IT-540B.

If you choose to paper file the amended Louisiana return, mail:

• the revised IT-540 (or IT-540B),
• an explanation of the change(s), and
• a copy of the amended federal return if one was filed. Mail the amended return to the address shown on your amended IT-540 (or IT-540B).

Be sure you check the box on Form IT-540 (or IT-540B) that it is an amended return.
