Illinois Statutes Chapter 35. Revenue § 200/14-25. Certificate of error; tax exempt property

(a) If the property became eligible for the exemption at an earlier time, a certificate of error shall be issued for the period of eligibility, but in no event, except as otherwise provided in this subsection (a), for more than the 3 assessment years immediately preceding the assessment year for which the exemption was approved. A certificate of error shall be issued for the period of eligibility, but in no event for more than the 5 assessment years immediately preceding the assessment year for which the exemption was approved, if the municipality requests the certificate of error before January 1, 1995.

(b) If the property is subsequently erroneously assessed as non-exempt, that error shall be remedied by the issuance of a certificate of error.

(c) If the owner failed to file an application for exemption, or a certificate of status under Section 15-10, for an assessment year following the assessment year for which the exemption was approved and the property remains eligible for exemption for the following year.
