Municipal and County Cannabis Retailers’ Occupation Tax Rate Changes, Effective January 1, 2026

To: All dispensaries engaged in the business of selling adult use cannabis at retail in taxing jurisdictions that have enacted Municipal or County Cannabis Retailers’ Occupation Taxes

Effective January 1, 2026, certain taxing jurisdictions have, by ordinance, imposed or changed their Municipal or County Cannabis Retailers’ Occupation Tax on the gross receipts from sales of adult use cannabis (65 ILCS 5/8-11-23; 55 ILCS 5/5-1006.8). These taxes are in addition to Illinois Retailers’ Occupation Tax (35 ILCS 120/3-10, 14) on general merchandise (6.25%) and any locally-imposed retailers’ occupation tax on general merchandise, which also apply to sales of adult use cannabis.

You must adjust your cash register and any computer program so that beginning on January 1, 2026, you will collect and pay the correct tax rate.

To verify your new combined state and local retailers’ occupation tax rates (i.e., State and local taxes) on adult use cannabis, go to the MyTax Illinois Tax Rate Finder at mytax.illinois.gov and select rates for January 2026.
