Chicago plans to charge the full 3 percent maximum local tax allowed on recreational marijuana sales, which are set to begin in January, according to Mayor Lori Lightfoot’s budget proposal.

The move isn’t unexpected. One of the selling points of legalizing marijuana sales was increased revenue for cashed-strapped state and local governments.

Cook County, which also has the option to charge up to 3 percent on recreational cannabis sales, hasn’t yet said how much it plans to charge. Local taxes are in addition to state taxes that range from roughly 20 to 30 percent, depending on the potency of the products.

The city says in its 2020 budget outlook that it expects to bring in just $3.5 million in revenue from marijuana taxes, but it represents just four months of revenue because under state law, tax collections won’t begin until September. Cannabis taxes could produce about $10 million annually in the early going. The city is facing a budget deficit this year of $838 million.

The city also says it expects it could ultimately have as many as 74 dispensaries by the end of next year, up from 11 medical dispensaries now operating in Chicago. State law allows those 11 dispensaries to sell recreational marijuana, and it allows those license holders to seek an additional license. Other dispensary license holders in the metro area also could seek licenses in Chicago.
