What is the cannabis tax rate in Illinois?

Illinois uses a tiered THC excise tax: 10% on flower at or below 35% THC, 20% on infused products (edibles, topicals, tinctures), and 25% on products above 35% THC (concentrates, high-potency vapes). On top of that, consumers pay 7% cultivation privilege tax (embedded in price), 6.25% state sales tax, up to 3% municipal tax, up to 3.75% county tax, and 1% RTA tax in the Chicago metro. The combined rate in Chicago on high-THC products reaches approximately 41.25%.

How much cannabis tax revenue has Illinois collected?

Illinois has collected approximately $1.7-1.9 billion in cannabis tax revenue from legalization through FY2024. Revenue is allocated to six categories: 35% General Revenue Fund, 25% R3 Program (community reinvestment), 20% DHS substance abuse and mental health, 10% Budget Stabilization, 8% local government crime prevention, and 2% public education and research.

How do Illinois cannabis taxes compare to neighboring states?

Illinois cannabis taxes are among the highest in the nation. Chicago consumers pay up to 41.25% total tax on high-THC products. By comparison, Missouri charges approximately 6% total (the lowest in the region since legalizing in February 2023), and Michigan charges approximately 16%. Even downstate Illinois flower at ~16% is nearly three times Missouri's rate. This disparity has driven significant cross-border shopping, particularly along the Missouri-Illinois border.

The Tax Stack

Illinois cannabis taxation is layered. Every purchase is subject to multiple taxes that stack on top of each other:

Tax	Rate	Notes
THC Excise — Flower ≤35%	10%	Standard flower and pre-rolls
THC Excise — Infused Products	20%	Edibles, topicals, tinctures
THC Excise — >35% THC	25%	Concentrates, high-potency vapes
Cultivation Privilege Tax	7%	Paid by cultivators, passed to consumers in pricing
State Sales Tax	6.25%	Standard Illinois sales tax
Municipal Tax	Up to 3%	Set by municipality
County Tax	Up to 3.75%	Cook County maximum
RTA Tax	1%	Chicago metro Regional Transportation Authority

What You Actually Pay

Product Type	Chicago	Downstate (No Local)
Flower under 35% THC	~26%	~16%
Infused products (edibles)	~36%	~26%
Concentrates / >35% THC	~41.25%	~31%

Chicago consumers face the highest combined rates in the nation on high-THC products. The ~41.25% total on concentrates means a $60 gram of live resin costs $84.75 after tax. Even standard flower at ~26% turns a $40 eighth into $50.40.

How Illinois Compares

State	Approx. Total Tax
Illinois (Chicago, high-THC)	~41.25%
Illinois (downstate, flower)	~16%
Michigan	~16%
Missouri	~6%

Missouri's 6% total tax rate is the most disruptive comparison. Since Missouri legalized in February 2023, Illinois border communities have hemorrhaged cannabis tax revenue to cheaper Missouri dispensaries.

DHS Substance Abuse & Mental Health	20%
Budget Stabilization Fund	10%
Local Government Crime Prevention	8%
