Illinois offers the following types of accounting licenses and privileges. Click on the tabs above to learn more about the requirements and procedures for each type of license.

Initial Certificate/Acceptance of Examination


Initial License

Illinois is a two (2)-tiered state, requiring individuals wishing to practice public accounting in Illinois to obtain a Certificate and a License to Practice.


Initial Certificate (Acceptance of Exam) (See 23 Ill. Adm. Code 1400.180)

Applicants who have passed the Uniform CPA Examination either in Illinois or in another jurisdiction may apply for the Initial CPA Certificate. Upon receipt of appropriate documentation, the Illinois Board of Examiners (ILBOE) will approve the candidate's certification and notify the candidate of the certificate number and date of issue. Illinois certification and licensing is a two (2)-step process; the CPA Certificate must be obtained prior to obtaining the CPA License to practice.


Initial License 

  • Applicants who passed the Uniform CPA Exam in Illinois, or another jurisdiction and are not licensed to practice public accounting, must obtain the certificate from the ILBOE before applying for the license.
  • Applicants who have passed the Uniform CPA Exam, and may or may not be licensed to practice public accounting in another jurisdiction, may apply for an Initial License from the Illinois Department of Financial and Professional Regulation (IDFPR).
  • CPA License. In order to perform the audit and attest function in Illinois, you must fulfill a one (1)-year experience requirement to qualify for a license to practice as a Licensed CPA.
    • The license is renewable every three (3) years and requires one hundred twenty (120) hours of Continuing Professional Education (CPE) for renewal. Without a license to practice public accounting, you may not express an opinion on a financial statement based on an audit or examination of a financial statement, or issue a report expressing assurance on a financial statement.
    • If you obtain a license to practice public accounting in Illinois, you are not required to register your certificate.
  • Effective July 1, 2012, Illinois no longer offers CPA Registration. A person who completed the CPA exam cannot just register with the IDFPR to practice accounting. Anyone using the title CPA or Certified Public Accountant must be licensed by the IDFPR as per 225 Ill. Comp. Stat. § 450/4(d).

Reciprocal License

Endorsement of License: An applicant having a valid, unrevoked license to practice as a CPA from a jurisdiction whose licensure requirements were equivalent to Illinois requirements at the time the license was issued and who is planning to relocate to Illinois must apply for an Endorsement of License from the Illinois Department of Financial and Professional Regulation (IDFPR), either through registration of applicant's current license or by reciprocal licensure.


  • Certified Public Accounting License: In order to perform the audit and attest function in Illinois, you must fulfill a one (1)-year experience requirement to qualify for a license to practice as a Licensed Certified Public Accountant. The license is renewable every three (3) years and requires one hundred twenty (120) hours of Continuing Professional Education (CPE) for renewal. Without a license to practice public accounting, you may not express an opinion on a financial statement based on an audit or examination of a financial statement, or issue a report expressing assurance on a financial statement. If you obtain a license to practice public accounting in Illinois, you are not required to register your certificate.


  • Effective July 1, 2012, Illinois no longer offers CPA Registration. A person who completed the CPA exam cannot just register with the IDFPR to practice accounting. Anyone using the title CPA or Certified Public Accountant must be licensed by the IDFPR as per 225 Ill. Comp. Stat. § 450/4(d).

Practice Privilege


Practice Privilege / Mobility / Interstate Practice

Mobility is a practice privilege that generally permits a licensed CPA in good standing to practice in a state from outside of their principal place of business without obtaining another license, so long as the licensee meets certain state specific conditions.


For state accountancy boards that have adopted the Uniform Accountancy Act § 23 Safe Harbor language for mobility, this will allow those licensees who had practice privileges prior to a specific date to proceed to practice, so long as they have a license in good standing and no other state specific restrictions apply. Currently, Delaware, Texas, and Pennsylvania have adopted the UAA Safe Harbor Language for Mobility.


As of January 1, 2026:

  • Notwithstanding any other provision of Illinois law, an individual or CPA firm who offers or renders professional services under this section, whether in person or by mail, telephone, or electronic means, shall be granted practice privileges in Illinois and no notice or other submission must be provided by any such individual or CPA firm.
