Combined Uniform Sales Tax Return
We are excited to announce a new Sales Tax Return is in development for online filing on Parish E-File! Each physical location of your business entity will report all State and Local sales and purchases activity not only from one centralized site but in one uniform return! File one combined return and Parish E-File will submit your State and Local Sales Tax returns to the taxing authorities for you!
A few things you should know about the Combined State and Local Sales Tax Return include:
- The new return will be available for the October 2025 Sales Tax filing period, due in November.
- The combined return must include your statewide sales activity by location within a single filing for the designated reporting period.
- The new return will replace the single and multi-jurisdictional returns currently available in Parish E-File.
- Your filing frequencies will need to be the same for the State and all Local authority accounts that will be included in the return.
- The new combined return will replace the Sales Tax returns only (the separate Hotel/Motel returns will remain available).
