Checking an Illinois CPA

CPA licenses in Illinois are issued by the Illinois Department of Financial and Professional Regulation (IDFPR), which has a free online license lookup. You can also search CPAverify.org. Illinois distinguishes a licensed CPA, who may offer services to the public, from someone who has only passed the CPA exam - so check for an active license.

Illinois taxes to know

  • Flat state income tax: individuals pay 4.95% of Illinois income, whatever they earn. Corporations pay a separate corporate rate plus the personal property replacement tax.
  • Sales tax: the state rate is 6.25%, and counties and cities add their own, so rates in and around Chicago are among the highest in the country.
  • Chicago has extra local taxes for some businesses, for example on restaurants, hotels and certain leases - a local accountant will know which apply to you.

Free help with a simple return

IRS-certified volunteers prepare simple federal and state returns for free through the VITA program at sites across Illinois, for people on low to moderate incomes.
