A 3D topographic map of Louisiana in 800×600 resolution, rendered with green uplands in the north and orange-brown coastal areas in the south. The Mississippi River and waterways are carved into the terrain. In the lower portion, large white 3D letters spell out “LOUISIANA CANNABIS TAX GUIDE,” contrasting sharply with the map’s colors.Key Points

  • Only medical cannabis is legal. Recreational (adult‑use) remains illegal (possession decriminalized up to 14 g, but no adult‑use market).

  • No state excise tax on cannabis until January 1, 2026. A 15 % wholesale excise tax (“HB 636, 2025 Reg. Sess.”) takes effect then.

  • Sales tax base is 5 %, with parish/city add‑ons driving combined rates to roughly 5 %–13.5 %.

  • Louisiana does not conform to federal IRC §280E. Medical operators may deduct ordinary business expenses on their state returns.

  • Returns are due on the 20th of the month following the reporting period. Monthly filings required if tax liability exceeds $1,000/month; otherwise quarterly. E‑filing via LaTAP is mandatory, and zero‑sales returns still must be filed.

  • Strict documentation and timely filings are essential—late or inaccurate filings can trigger penalties, audits, or license jeopardy.
