Louisiana state income tax deadline is May 15

BATON ROUGE – The deadline for 2023 Louisiana state income tax is Wednesday, May 15.

Taxpayers can file their returns electronically through File Online, the state’s free web portal for individual tax filers. They can also submit their returns using commercially available tax preparation software, or with printed state returns available at Tax Forms.

Act 410 of the 2022 Regular Session of the Louisiana Legislature created an automatic six-month filing extension, available to taxpayers who need extra time to prepare their state individual income tax returns. For tax year 2023, the extended due date is Nov. 15, 2024. Individual taxpayers who cannot file their returns by May 15 do not need to submit a request to obtain the automatic filing extension.

The automatic extension applies only to the filing of state income tax returns. It does not provide additional time to pay taxes due. Tax payments submitted after the May 15, 2024, deadline are subject to penalties and interest.
