Deductions work by reducing the amount of assessed value a taxpayer pays on a given parcel of property. Credits work by reducing the amount of property tax liability associated with a given parcel of property.
Taxpayers do not need to reapply for deductions or credits annually. Reapplication should only occur if the property is sold or the title is changed.
To obtain a new deduction or credit, a taxpayer must submit an application to the county auditor. Deductions and credits applied for before the annual deadlines will be applied to the next year’s tax bill. For example, a homeowner who completes the application on or before January 15, 2026, will see the deduction applied to their 2025 Pay 2026 tax bill.
