Indiana Code Title 6. Taxation § 6-1.1-12-10.1

Sec. 10.1. (a) Except as provided in section 17.8 of this chapter and subject to section 45 of this chapter, an individual who desires to claim the deduction provided by section 9 of this chapter must file a sworn statement, on forms prescribed by the department of local government finance, with the auditor of the county in which the real property, mobile home, or manufactured home is located.  To obtain the deduction for a desired calendar year in which property taxes are first due and payable, the statement must be completed, dated, and filed with the county auditor on or before January 15 of the calendar year in which the property taxes are first due and payable.  The statement may be filed in person or by mail.  If mailed, the mailing must be postmarked on or before the last day for filing.

(b) The statement referred to in subsection (a) shall be in affidavit form or require verification under penalties of perjury.  The statement must be filed in duplicate if the applicant owns, or is buying under a contract, real property, a mobile home, or a manufactured home subject to assessment in more than one (1) county or in more than one (1) taxing district in the same county.  The statement shall contain:

(c) In order to substantiate the deduction statement, the applicant shall submit for inspection by the county auditor a copy of the applicant's and a copy of the applicant's spouse's income tax returns that were originally due in the calendar year immediately preceding the desired calendar year in which the property taxes are first due and payable and for which the applicant and the applicant's spouse desire to claim the deduction.  If either was not required to file an income tax return, the applicant shall subscribe to that fact in the deduction statement.

(d) This section applies only to property taxes imposed for an assessment date before January 1, 2025.

(e) This section expires January 1, 2027.
