Tax credit
#01
Federal Residential Clean Energy Credit (Section 25D) - ENDED
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025. Cash and loan purchases made now receive no federal tax credit, and Indiana has no state income tax credit for solar to fall back on.

#02
Federal Commercial ITC (Section 48E) - via Lease / PPA
Section 48E, the commercial Clean Electricity Investment Credit, survives at 30 percent and is available to third-party owners of residential systems under leases and power purchase agreements. The provider claims it and may reflect part of the value in the rate offered. Ask what they claim and what actually reaches you, and confirm with a tax advisor.

#03
Net metering CLOSED to new customers (SEA 309)
Senate Enrolled Act 309 ended net metering for new solar customers no later than July 1, 2022. Existing customers were grandfathered on a schedule: a system installed before 2018 keeps full net metering until July 1, 2047, and a system installed between the start of 2018 and the close of the programme keeps it until July 1, 2032. Those dates matter when buying a home with an existing array, because a grandfathered system is worth substantially more than a new one.
Utility
#04
Excess Distributed Generation (EDG) credit - 125% of wholesale
What replaced net metering. The Indiana Utility Regulatory Commission sets the Excess Distributed Generation credit at the average wholesale cost of electricity from the prior year plus 25 percent. In practice that has produced a credit roughly 70 to 80 percent below the retail rate. Because it is based on the prior year wholesale cost it is recalculated rather than fixed, and it is set per utility, so confirm the current figure with the utility that actually bills you.
Program
#05
Instantaneous netting upheld by the Indiana Supreme Court
The Indiana Supreme Court held that a utility may use instantaneous netting rather than monthly netting, reasoning that when the General Assembly moved to the excess distributed generation scheme it did not direct utilities on how often excess generation must be measured. Under instantaneous netting a customer pays the full retail rate for all power drawn from the grid while all solar sent to the grid earns only the Excess Distributed Generation rate. That removes the monthly offset that used to soften the gap, and it makes self-consumption far more valuable than export. Ask which netting method your specific utility applies.
Tax credit
#06
Sales Tax Exemption (7%)
Indiana exempts solar panels, inverters, mounting hardware and other qualifying system components from the 7 percent state sales tax. Nothing is claimed and nothing is filed: the tax should simply be absent from your quoted price, so ask directly whether the price includes any Indiana sales tax.
Tax credit
#07
Property Tax Exemption
Indiana exempts the added value of a residential solar system from property tax assessment, so installing solar should not raise your assessment. If a savings model shows an assessment increase attributable to the array, that is a modelling error. Confirm the filing your county requires, since assessment procedures are administered locally.
Net metering · Indiana
Net metering closed; EDG credit at 125% of wholesale
Indiana closed net metering to new solar customers under Senate Enrolled Act 309, no later than July 1, 2022. New residential systems instead receive the Excess Distributed Generation credit, which the Indiana Utility Regulatory Commission sets at the average wholesale cost of electricity from the prior year plus 25 percent. That has produced a credit roughly 70 to 80 percent below the retail rate, so an exported kilowatt hour is worth a small fraction of one you consume yourself. A second change compounds the first. The Indiana Supreme Court held that a utility may measure excess generation instantaneously rather than netting across a billing period, on the reasoning that the statute does not direct utilities on how often the measurement must be made. Under instantaneous netting a household pays the full retail rate for everything it draws from the grid at any moment while everything it sends to the grid earns only the Excess Distributed Generation rate, with no monthly offset in between. The practical consequences are large. A system sized to annual consumption will export a great deal of its midday output at the low rate, so a smaller system matched to daytime load frequently returns better. Shifting flexible loads into daylight converts low-value exports into full-value offsets at no cost, and storage carries more weight here than the national conversation suggests. Existing customers were grandfathered: systems installed before 2018 keep full net metering until July 1, 2047, and those installed between the start of 2018 and the close of the programme until July 1, 2032.
