Browse CPAs by City in Illinois

Illinois's substantial CPA market serves a diverse economy centered on Chicago's global financial and corporate hub. The Illinois Board of Examiners requires 150 semester hours for licensure. CPAs must complete 120 hours of continuing professional education every three years, including 4 hours of professional ethics and 15 hours annually in technical subjects.

Key Tax Considerations: Illinois has a flat 4.95% individual and corporate income tax, but high property taxes and complex local tax structures create planning opportunities. CPAs commonly handle multi-jurisdictional taxation (especially for Chicago businesses), sales and use tax compliance, property tax appeals, and helping high-income residents evaluate relocation to neighboring states with lower taxes. Recent tax law changes require practitioners to stay current on evolving requirements.

Industry Specializations: Financial services and commodities trading, manufacturing and industrial production, transportation and logistics (major rail and shipping hub), healthcare systems, technology, food processing, and professional services are primary focus areas. Chicago CPAs often specialize in derivatives and options trading taxation, municipal finance, and serving Fortune 500 corporate headquarters.

For CPA Professionals: The Illinois CPA Society provides extensive resources, particularly in the Chicago area. Chicago offers big-city opportunities with all major national firms present, while suburban and downstate markets (Springfield, Peoria, Rockford) provide alternatives with lower cost of living. The state faces fiscal challenges and out-migration of high earners, but Chicago's position as a global business center maintains strong demand for sophisticated accounting services.
