How can I file an amended return?

In order to amend the amounts reported for the computation of income or franchise taxes, you must file an amended (corrected) Form CIFT-620. File the amended return as if the original return was not filed and do not make any adjustments for refunds previously received or for payments previously made. This information is already on file and LDR will adjust your account accordingly. Louisiana Revised Statute 47:287.614(C) requires every taxpayer whose federal return is adjusted to furnish a statement disclosing the nature and amounts of such adjustments within 180 days of the final determination of such adjustments from the Internal Revenue Service. This statement should accompany the Louisiana amended return.

A corrected return for the tax year being amended should be submitted along with an explanation of the change(s) and a copy of the federal amended return, Form 1120X, if one was filed. The return should be clearly marked with an "X" in the "Amended Return" box. Mail an amended return to the following address:

Louisiana Department of Revenue
P.O. Box 91011
Baton Rouge, La 70821-9011

You also have the option of filing the amended return electronically through the LDR Fed/State e-file program for corporation income and franchise tax returns
