Do I have to include a copy of my Federal return with my Louisiana state tax, if I am filing by mail?

Generally, your federal tax return should not be included with your Louisiana State Tax Return.  

However, if you file a Schedule H (disaster relief) with your Louisiana return, then you'll need to include a copy of your federal return that indicates the amount of the credit, a copy of Federal Form 3800, and a copy of the appropriate IRS form to substantiate the amount of the credit.

Individual Louisiana Returns can be mailed as follows: 

A return for which a payment is due should be mailed to: 

• P.O. Box 3550, Baton Rouge LA 70821-3550. 
• Print the last four digits of your Social Security Number on your check or money order.

All other individual income tax returns should be mailed to:

• P.O. Box 3440, Baton Rouge, LA 70821-3440

It is state dependent......in MS you are not required to submit a federal return along with your state.
