I have already filed my Louisiana income tax return for the year covered by the notice or by the proposed assessment. What must I now do to show the department that the return has been filed?

If the return that was submitted indicates no tax due or a refund due, please provide a complete copy of the return to the department. If the department’s records indicate that the refund was not issued, the department will issue a refund for the correct amount due. If the return was accompanied by a personal check, please furnish a copy of the front and back of the cancelled check. If the payment was by money order or cashier’s check, please furnish a copy of the cancelled original receipt. If the taxes were paid in cash to the department, please furnish a copy of the official department receipt.
