State tax deduction for renewable energy systems

Indiana Department of Local Government Finance (DLGF) · State program

Property-tax deduction; the official page does not state a single statewide dollar cap on the lines reviewed.

Indiana has property-tax deductions for certain renewable energy systems installed on a property. This is not a wildfire program, but it is a statewide tax incentive homeowners can use for qualifying systems such as solar, wind, geothermal, and hydroelectric devices.

Program details

How it works

The DLGF deductions-and-credits page lists Indiana property tax benefits and states that certain renewable energy systems installed on a property may qualify for a property tax deduction.

What the money covers

The page names these qualifying systems:

  • solar
  • wind
  • geothermal
  • hydroelectric devices

Amounts and matching

The page does not give a single dollar cap on the lines reviewed. A related DLGF report says the solar energy heating or cooling system deduction equals out-of-pocket expenditures for components and labor involved in installation, while other renewable-device deductions are based on the assessed value difference with and without the device.

How to apply

The page says homeowners should contact their county auditor for questions regarding deductions or eligibility, and that the state form is available through DLGF.

Timing and deadlines

The page gives an example that a homeowner who completes the application on or before January 15, 2026, will see the deduction applied to the 2025 Pay 2026 tax bill.
