The Board of Directors of the LATA approved access to TRIALS to all tax practitioners to help better serve the taxpayer community.
The Tax Research Information and Litigation Summary (TRIALS) system was developed as a research tool for local sales and use tax in the state of Louisiana. The information in TRIALS is maintained and updated by the LATA. TRIALS is intended to be used for information purposes only, and is not to be considered a legal opinion or legal advice.
PLEASE NOTE: The information in TRIALS is currently updated through the 2024 Regular Session of the Louisiana Legislature.
