The mailing address for your Louisiana individual income tax return depends on whether you are including a payment with your return.

If you are mailing a return with a payment:

Louisiana Department of Revenue
P.O. Box 3550
Baton Rouge, LA 70821-3550

If you are mailing a return without a payment:

Louisiana Department of Revenue
P.O. Box 3440
Baton Rouge, LA 70821-3440

These mailing addresses apply only to Louisiana Individual Income Tax returns.

LDR encourages taxpayers to file electronically whenever possible. Electronic filing is the fastest, most secure way to file your return and generally results in faster processing and refunds.

If you choose to mail your return:

• Use the correct mailing address based on whether you are including a payment.

• Sign and date your return before mailing.

• Include all required schedules, forms, and supporting documentation.

• If mailing near the filing deadline, allow sufficient time for delivery and ensure your return is properly postmarked.

Recommendation: After filing your return, you can monitor its progress using LDR's Where's My Refund? tool if you are expecting a refund. If you owe tax, you may also choose to make your payment electronically through LaTAP, even if you mail your return. This can provide faster payment processing and immediate confirmation of your payment.
