No, there is no provision in the law that allows a preparer to opt-out.
However LAC 61:III.1501.E provides that the secretary may waive the electronic filing requirement if it is determined that complying with the requirement would cause an undue hardship. Waivers must be requested and and each request will be considered individually. Requests should be addressed to:Tax Administration Division
Post Office Box 3193
Baton Rouge, Louisiana 70821-3193
Requests should include the tax preparer's identification number and the valid reasons why the tax preparer cannot comply with the electronic filing mandate.
