IN HB1030

Creates a 100% property tax deduction against the assessed value of eligible mortise and tenon barns for owners and qualifying contract purchasers.

Defines eligible barns as structures built before 1936 using heavy wooden timbers joined with wood-pegged mortise and tenon joinery that retain substantially the same size, design, and construction as the original.

Requires eligible applicants to file a certified deduction application with the county auditor in the year preceding the year the deduction will first apply, with verification by the township or county assessor.

Allows approved deductions to automatically renew annually unless the county auditor determines the applicant is no longer eligible, without requiring reapplication if the person remains qualified.

Becomes effective immediately upon passage and is declared an emergency measure.
