US Solar Energy Tax Credit Ends on 31 December 2025

The federal tax credit period is rapidly closing for homeowners in the United States looking to transition to solar energy. Homeowners who install solar panels on their roofs within the year 2025 have the opportunity to get back approximately one-third of their expenses as a federal tax credit. However, a new law signed last summer significantly shortens the duration of these incentives, almost completely ending the support. If solar energy systems are placed in service in 2026, no federal tax credit or incentive will be available. This means not just a reduction in the credit, but the effective end of the program.

This program, known as the Residential Clean Energy Credit, is provided under Section 25D of the Internal Revenue Code. This system allows deducting 30 percent of the solar panel cost directly from federal tax liability. The said deduction is not a tax deduction, but a direct tax credit; meaning the full value is deducted for every dollar. For example, a rooftop solar energy system costing 24,000 dollars provides the taxpayer with a direct credit of 7,200 dollars. There is no upper limit on the credit amount, and if the credit amount exceeds the tax burden in a given year, the remaining balance rolls over to the following years as long as it exists in the law books.

Initially set at 30 percent with the Inflation Reduction Act of 2022, this tax incentive was planned to be extended until the year 2032. Under the relevant law, the credit was expected to decrease to 26 percent in 2033 and 22 percent in 2034. However, the new law called One Big Beautiful Bill Act (OBBBA), signed on 4 July 2025, dramatically changed this timeline. According to the new regulation, eligible expenses for residential solar energy properties must be made by 31 December 2025, or the systems must be placed in service before this date. Otherwise, zero incentive will be provided at the federal government level for systems placed in service in 2026 and beyond.

Homeowners wishing to take advantage of this tax credit must meet certain conditions. The credit covers homeowners who install a solar energy system in a home located within the borders of the United States and applies to both primary and secondary residences. Only rented properties where the owner does not live cannot benefit from this support. In addition, the system must be purchased or financed; leased panels or Power Purchase Agreements (PPAs) cannot benefit from this exception, because in these cases the credit goes to the solar company since they own the equipment. Those who install their systems in 2025 need to fill out IRS Form 5695, attach it to their federal tax return, multiply the total eligible cost by 30 percent, and transfer it to Schedule 3 of Form 1040.

Finally, there are some critical pitfalls and financial details regarding the process that need to be considered. The term 'placed in service' does not just mean the panels are mounted on the roof, but indicates that the system is fully operational. If the company switch is turned on in 2026, solar panel owners might miss the deadline. Additionally, this credit is not a refundable credit; meaning it can zero out your federal income tax liability but does not refund more money than you paid. The practical benefit may be less for low-income individuals or retirees. In addition to this, considering economic pressures such as high credit card interest rates and inflation in 2026, using this 30 percent tax credit to pay off debts stands out as an extremely strategic financial move. Readers should also remember that even if federal incentives end with the OBBBA law, they should still research solar energy rebates and tax exemptions that remain valid at the state level.
