The Illinois Department of Revenue (IDOR) today posted a notice for all dispensaries in taxing jurisdictions that have enacted Municipal or County Cannabis Retailers’ Occupation Taxes. These taxes are in addition to Illinois Retailers’ Occupation Tax on general merchandise (6.25%) and any locally imposed retailers’ occupation tax on general merchandise, which also apply to sales of adult use cannabis.

Effective July 1, 2025, 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. The following municipalities are imposing Municipal Cannabis Retailers’ Occupation Tax: Breese, Carpentersville, Crest Hill, Diamond (Grundy), Diamond (Will), Du Quoin, Elizabeth, Forsyth, Lake in the Hills, and Mount Carmel.

According to the press release, dispensaries must adjust cash registers and any computer programs so that, beginning on January 1, 2026, dispensaries will collect and pay the correct tax rate. Municipal and County Cannabis Retailers’ Occupation Taxes are imposed on gross receipts from adult use cannabis sold at retail. These taxes, however, are not imposed on cannabis purchased under the Compassionate Use of Medical Cannabis Program Act. To verify 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.

What is the tax rate that counties and municipalities can impose by ordinance on retail sales of cannabis?

Municipalities may impose a tax on retail sales of cannabis, other than medical cannabis, at a rate that may not exceed 3%, imposed in one-quarter percent (0.25%) increments. Counties may impose a tax (also in one-quarter percent increments) on retail sales of cannabis, other than medical cannabis, at the following rates:

• In unincorporated areas of the county, the rate may not exceed 3.75%.
• In a municipality located in the county, the rate may not exceed 3%.

For implementation of the tax by the Illinois Department of Revenue (IDOR), municipalities and counties must submit their ordinances to IDOR by April 1 for July 1 implementation and by October 1 for implementation on the following January 1.
