Chicago's Local Taxes & Fees: The Rules That Matter

Every city handles local taxes & fees a little differently. In Chicago, Illinois, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Business Tax Classification

Chicago does not levy a city business income tax. The Business License Tax under MCC 4-4 funds licensing through the Department of Business Affairs and Consumer Protection. Illinois imposes a 7 percent corporate income tax plus the 2.5 percent Personal Property Replacement Tax.

Key details: City licensing: MCC 4-4. Limited Business License: $250 biennial. IL corporate tax: 7 percent under 35 ILCS 5. PPRT add-on: 2.5 percent C-corp. Cook commercial assessment: 25 percent of value.

Operating without a required business license triggers fines of $250-$1,000 per day under MCC 4-4-340, license revocation, and possible misdemeanor charges. State tax violations trigger Illinois Department of Revenue audits and 10-30 percent penalties.

Mansion Tax (Measure ULA)

Chicago has no mansion tax. The March 2024 Bring Chicago Home referendum, which would have raised the transfer tax tier on sales over $1 million, was rejected by voters. The flat Real Property Transfer Tax under MCC 3-33 still applies citywide.

Key details: City rate: $3.75 per $500 buyer. CTA supplement: $1.50 per $500 seller. Authority: MCC 3-33. Mansion tax: Rejected March 2024. Combined city total: $5.25 per $500.

Failing to pay the Real Property Transfer Tax blocks deed recording at the Cook County Recorder, triggers penalties of 5 percent of tax due plus 12 percent annual interest, and personal liability under MCC 3-33-100.

Vacancy Tax

Chicago has not adopted a vacancy tax on empty homes or storefronts. Illinois law does not authorize one. The city instead targets blighted vacant property through the Vacant Building Ordinance MCC 13-12-125 registration fees and code enforcement.

Key details: Vacancy tax: None adopted. Vacant building registration: MCC 13-12-125. Registration fee: $250 annually. Daily penalty: $200-$1,000.

Failure to register a vacant building under MCC 13-12-125 triggers fines of $200-$1,000 per day, demolition liens, and personal liability for owners. There is no vacancy tax penalty since no vacancy tax exists.

The rules around vacancy tax in Chicago lean permissive, but that does not mean anything goes.

Affordable Housing Linkage Fee

Chicago's Affordable Requirements Ordinance MCC 2-44-080 requires residential developments of 10 or more units that receive city zoning bonuses, financial assistance, or are on city-owned land to set aside 20 percent affordable units, build off-site, or pay an in-lieu fee.

Key details: Authority: MCC 2-44-080. Threshold: 10 or more units. Set-aside: 20 percent affordable. Downtown in-lieu fee: About $135,000 per unit. Trigger: City bonus, land, or assistance.

Failure to comply blocks zoning approval and certificate of occupancy. The Department of Housing may seek injunctive relief, recapture of bonuses, fines up to $500 per day per unit, and revocation of city financial assistance under MCC 2-44-090.

Compared to other cities, Chicago takes a harder line on affordable housing linkage fee. The enforcement and penalty structure reflects that.

Parking Tax

Chicago's Parking Tax under MCC 4-236 charges 22 percent on weekday daily commercial parking and 20 percent on weekend rates, reaching 23.25 percent for valet. Combined with the Cook County parking tax, downtown garage tax burdens are the highest in the United States.

Key details: Authority: MCC 4-236. Weekday rate: 22 percent of charge. Weekend rate: 20 percent of charge. Valet rate: 23.25 percent. National ranking: Highest in U.S..

Failing to register, collect, or remit Chicago parking tax is a misdemeanor under MCC 4-236-040 with civil penalties of 25 percent of tax due plus 12 percent annual interest, license revocation, and personal liability for owners.

This is not one of those rules that cities tend to ignore. Chicago actively enforces its parking tax requirements.
