Compare state rebates, tax credits, and financing guidance, including eligibility dates, application records, contracts, and repayment questions.
Incentives are time-limited offers from different authorities: the IRS, state agencies, utilities,
and local governments. Each has its own eligibility, equipment, installation-date, and
documentation requirements — and its own expiration date.
An incentive does not waive permits, approvals, or equipment requirements, and eligibility terms
change. A rebate page that remains online can describe an expired program; the current program
terms and dates control. Financing products are contracts — read the disclosures before signing.
No, for new work: both federal home energy tax credits were terminated for property placed in service or expenditures made after December 31, 2025, by the One Big Beautiful Bill Act (P.L. 119-21). Qualifying 2025 and earlier installations can still be claimed, and an unused Residential Clean Energy Credit (25D) carries forward to 2026 and later years.
For the federal residential clean energy credit (25D) and energy efficient home improvement credit (25C), the date the property is installed and placed in service is the key date — and, as amended in July 2025, both credits end for property placed in service (25C) or expenditures made (25D) after December 31, 2025. The federal state-run rebate programs (HOMES and HEEHRA) run on a longer clock: funds remain available through September 30, 2031. Dated records prove which side of the cutoff your project falls on.
PACE financing pays for home improvements through an assessment on your property tax bill, secured by a lien on your home. Missed payments can lead to foreclosure or a tax sale. Before signing, compare the full cost, check whether your mortgage permits the lien, and confirm what happens when you sell or refinance. Federal Regulation Z ability-to-repay requirements apply to covered residential PACE transactions from March 1, 2026; they do not make PACE government-insured or guarantee that you can afford it.
It depends on your state and local assessment rules. California, Florida, and Texas each have official rules that keep some or all of the value of qualifying renewable energy devices out of the property tax base, but the details — device definitions, deadlines, and how long the protection lasts — differ by state.
Keep the documentation that proves what you bought, what it cost, when it was installed, and that it meets the program's requirements: itemized receipts and invoices, the manufacturer's certification or qualified-manufacturer identification (QMID) where required, placed-in-service documentation, and the program paperwork for any rebate you receive. The IRS says to keep records as long as needed to prove the items on your tax return, and rebate programs run by states, territories, and Tribes set their own paperwork rules.
Before signing, check the installer, equipment, total price, financing, warranties, roof costs, savings assumptions, and cancellation terms. Federal cooling-off rules and state contract protections have different triggers. Arizona, South Carolina, Pennsylvania, and Rhode Island examples below show why the contract type and location matter.
A tax credit reduces tax, a deduction reduces taxable income, a rebate offsets costs, and financing must be repaid. New installations after 2025 do not qualify for sections 25C and 25D; earlier qualifying work and carryforwards require the applicable tax-year rules. Check current rebate and assistance programs separately.
Before spending money, confirm eligibility, available funding, application deadlines, and any reservation requirement with the program administrator. Keep the current terms and your award or reservation. Discovery tools can help locate programs, but do not guarantee eligibility or payment.
