Quick Answer: Your Guide to Indiana Solar Permits & Incentives

Solar installation in Indiana involves two separate tracks: permits and incentives. No single state agency handles both.

Permits are issued by your local Authority Having Jurisdiction (AHJ), usually your city or county building department. The state sets interconnection standards through the Indiana Utility Regulatory Commission (IURC), but your building permit, electrical permit, and any zoning approvals come from local government.

Incentives come from multiple sources:

A federal 30% Residential Clean Energy Credit (IRS §25D) with no dollar cap.
A state Renewable Energy Property Tax Exemption, amended by S.B. 1 of 2025 and expiring January 1, 2027.
Net billing through your investor-owned utility, which replaces the old retail-rate net metering.
Utility-specific programs like NIPSCO's Feed-In Tariff (closed to new applicants as of April 2026).

Property tax exemptions and net billing rules have changed recently. Verify any information published before 2024 against current Indiana Department of Local Government Finance (DLGF) and IURC guidance.

Federal Tax Deductions

The IRS offers a 30% uncapped federal tax credit under §25D for residential solar PV, solar water heating, battery storage (≥3 kWh), geothermal, and small wind systems through 2032, with a step-down in subsequent years. This credit is stackable with state and utility rebates. Consult a tax professional for personalized advice and to ensure compliance with current regulations.
