IRS guidance says the residential clean energy credit is not available for expenditures made after December 31, 2025. The IRS FAQ further says an installation completed after that date is treated as an expenditure made after the deadline, even if you paid earlier. A signed contract, deposit, or financing approval does not by itself preserve eligibility.
State, local, and utility incentives may still exist, but they depend on your location, utility territory, system, ownership structure, funding, and application timing. Verify every claimed benefit with the program administrator, utility, and—where tax treatment is involved—a qualified tax professional before signing.

What solar tax credits and incentives can I still get, and what should I check before signing?
For homeowners evaluating a proposal in 2026, the first question is whether the claimed benefit is federal, state, local, or utility-based. The federal residential clean energy credit has ended for qualifying expenditures after December 31, 2025. Other programs may remain, but none should be treated as guaranteed until you confirm the exact program rules and your eligibility.
Use the following order when reviewing an offer:
- Identify the precise incentive and the law or program that creates it.
- Confirm the qualifying date, application deadline, funding status, and ownership requirements.
- Verify interconnection and export-credit assumptions with your utility.
- Compare complete written bids, including total cost and production assumptions.
- Read financing, maintenance, cancellation, transfer, and end-of-term clauses.
The 2025 federal credit change
What the IRS says now
IRS Publication 530 (2025) and the IRS FAQ on the Public Law 119-21 energy-credit changes state that residential clean energy credits cannot be claimed for expenditures made after December 31, 2025. The FAQ addresses a common misunderstanding: if installation is completed after December 31, 2025, the expenditure is treated as made after that date, even when the homeowner paid before the deadline.
#1 Best Overall
That means the following events do not, by themselves, establish eligibility for a post-deadline installation:
- Signing a contract before December 31, 2025.
- Paying a deposit or the entire contract price before that date.
- Opening a solar loan or arranging financing before that date.
- Receiving an invoice dated before the deadline.
The controlling facts include the applicable tax year and when the qualifying expenditure is treated as made under current IRS guidance. Ask any salesperson promising a federal credit to identify the exact credit, statutory provision, tax year, and qualifying date in writing. If the promise concerns an earlier installation, use the IRS instructions for the relevant return year rather than relying on a current sales presentation.
What qualified under the earlier credit
For years in which the credit applied, IRS guidance identified qualified solar electric property among the eligible categories. Certain labor allocable to onsite preparation, assembly, or original installation could be included, as could piping or wiring needed to interconnect the property with the home. Homeowners were advised to retain purchase receipts and installation records, and eligible claimants used Form 5695 according to the instructions for the applicable year.

The credit was a tax benefit claimed on a return, not an automatic point-of-sale discount. An installer cannot “give” you the federal credit, and a projected credit is not guaranteed cash savings. Your filing status, tax liability, and the law for the applicable year determine the result.

How to verify state, local, and utility incentives
Start with the official administrator
State, municipal, and utility programs can have separate rules for equipment, system size, property type, income, ownership, interconnection, and application timing. Ask the contractor for the program’s exact name and administrator, then confirm the information directly. The Department of Energy identifies the Database of State Incentives for Renewables & Efficiency (DSIRE) as a resource for finding state and local policies, but a database listing is a starting point—not proof that funds remain or that your project qualifies.
For each incentive, obtain these details before treating it as part of the deal:
- Official program name and administering agency or utility.
- Current eligibility rules, including customer, property, income, equipment, and ownership conditions.
- Whether funds are available and whether awards are first-come, reserved, or capped.
- Application, pre-approval, inspection, and completion deadlines.
- Required forms, invoices, permits, interconnection documents, and proof of payment.
- Whether the incentive is paid to you, assigned to an installer, or reflected as a contract reduction.
- Any clawback, recapture, transfer, or performance requirements.
Do not assume a “rebate” is tax-free
An incentive’s marketing label does not determine its federal tax treatment. IRS guidance explains that public-utility subsidies and state incentives can have tax consequences depending on the facts. Ask the administrator how the payment is reported and discuss the treatment with a qualified tax professional. Do not subtract an advertised rebate from your expected tax bill until you know whether it affects your basis, taxable income, or another tax calculation.

Confirm utility interconnection and export compensation
Your utility controls the practical terms for connecting a system and crediting electricity sent to the grid. Contact the utility—not only the installer—and ask for the tariff and application requirements that apply to your service address.
Questions for the utility
- What interconnection application and engineering review are required?
- Are there system-size, inverter, transformer, or service-panel limits?
- Must approval occur before equipment is installed or before an incentive application is filed?
- What export-compensation rate and bill-credit method apply?
- Are credits based on retail rates, avoided cost, time of use, or another tariff?
- How are fixed charges, minimum bills, demand charges, and unused credits handled?
- Can the tariff change for new systems, and does the agreement have a term?
“Net metering” is not a universal one-for-one credit, and it does not guarantee that your utility bill will disappear. Export rates and eligibility vary by state and utility. Require the proposal to state the utility tariff and assumptions used in its savings estimate, then compare those assumptions with the utility’s written information.
Compare complete solar proposals, not headline prices
The Federal Trade Commission advises homeowners to compare detailed bids and ensure that the design fits the home. Ask every bidder to use the same recent electricity-usage history and utility assumptions so the comparison is meaningful.
System and price details to require
- System size, stated in kilowatts, and equipment models.
- Estimated annual production and the method or assumptions used.
- Total installed price, including design, permitting, electrical work, inspections, interconnection, taxes, and fees.
- Any battery, roof work, service-panel upgrade, monitoring, or maintenance charges.
- Production guarantees, measurement period, exclusions, and the remedy if output is below the guarantee.
- Expected completion date and what happens if permitting or interconnection is delayed.
Do not treat a national installation statistic as a household savings estimate. The Consumer Financial Protection Bureau reported 6.8 gigawatts of direct-current residential solar capacity installed nationally in 2023—13% more than in 2022 and 62% more than in 2021. That is market context, not evidence of your likely payback or bill reduction.

Why savings estimates differ
A credible estimate must account for system production, your usage profile, utility rates and fixed charges, export compensation, financing costs, maintenance, degradation assumptions, and any changes to the tariff. No single national savings figure applies to every home. Request the underlying production and billing assumptions rather than relying on a percentage-of-bill claim.

Check installer qualifications, warranties, and roof obligations
Before signing, check the installer’s history with state and local consumer-protection agencies and the contractor licensing board. Ask which licenses, permits, and bonds are required in your jurisdiction and which entity will actually perform the electrical and roofing work.
Warranty questions
- How long are the equipment warranties for panels, inverters, batteries, and monitoring hardware?
- How long is the workmanship warranty, and what exclusions apply?
- Who handles warranty claims if the installer closes, changes ownership, or stops servicing your area?
- Who pays for labor, shipping, diagnostics, and removal during a repair?
- Who monitors performance, and how quickly must a service request be answered?
- Does the installer remain responsible for roof leaks, flashing, or damage caused during installation?
- What happens to roof warranties if a third party later removes and reinstalls the system?
Put the answers in the contract or an attached warranty schedule. A brochure or verbal promise is difficult to enforce if it conflicts with the signed agreement.
Understand who owns the system and the incentives
Solar contracts generally use one of three structures. Ownership determines who receives available incentives, who maintains the equipment, how payments are calculated, and what must happen if you sell the home.
Recommended Free Tools
| Structure | Who owns the equipment | What you pay | Terms to scrutinize |
|---|---|---|---|
| Cash purchase or loan | The homeowner, subject to any loan lien or security terms | The purchase price, or loan principal, interest, and fees | Financed principal, interest rate, dealer or origination fees, payment timing, maintenance duties, incentive allocation, and lien or security provisions |
| Lease | The provider | Scheduled lease payments | Escalator, maintenance, production commitments, transfer or buyout terms, removal or renewal options, early-exit costs, and home-sale requirements |
| Power purchase agreement | The provider | A contracted price per kilowatt-hour generated | Per-kilowatt-hour price, escalator, production estimate, minimum-production remedy, utility-bill exposure, transfer, and termination terms |
Purchase with cash or a loan
With a purchase, you generally own the system and take responsibility for maintenance unless the contract says otherwise. A loan can add interest, origination or dealer fees, a lien, and payment assumptions that are not visible in a cash price. Compare the total amount paid over the loan term—not just the monthly payment—and verify whether any claimed incentive is assigned to the lender or remains your responsibility.
Best Value

Lease
In a lease, the provider owns the equipment and you make scheduled payments. Read the escalator, production commitment, maintenance scope, buyout formula, removal rules, renewal options, and transfer process. A long-term lease can make an early exit difficult and may complicate a home sale if a buyer must qualify for an assumption or if the provider requires a buyout.
Power purchase agreement
With a PPA, you buy the electricity the system produces at the contract’s stated per-kilowatt-hour price. Review the price escalator, estimated and minimum production, remedy for underproduction, and the portion of your electricity that will still come from the utility. The provider’s ownership can affect who receives incentives and who controls equipment decisions. Ask who owns any renewable energy certificates or other environmental attributes if that matters to you.

Before signing, request the complete agreement—not a summary screen, tablet form, or partially completed application. Confirm:
- Every upfront fee, deposit, financing charge, and recurring payment.
- Whether payments increase and on what schedule.
- When payments begin, including any period before permission to operate.
- Performance guarantees, exclusions, measurement methods, and remedies.
- Cancellation rights, statutory cooling-off periods, and the deadline for exercising them.
- Early-termination, removal, buyout, and transfer charges.
- What happens if the project is denied permits, fails interconnection, or differs from the approved design.
- Whether a lender, installer, or provider can place a lien or security interest on the property.
- Who pays for repairs, insurance, monitoring, roof work, and equipment removal.
- How a sale, refinance, divorce, death, or move affects the agreement.
Have a lawyer review a long-term or property-secured agreement if you do not understand its obligations. Contract rights and cancellation rules depend on state law and the actual document.
Recognize pressure tactics and “free solar” claims
The FTC warns against claims that government programs cover the entire cost or that solar is free. “Free” may describe a promotional payment structure, a lease, or a projected incentive—not equipment with no financial obligation.
The FTC’s consumer alert says: If someone is rushing you to sign a contract, or insists you sign an agreement on an electronic tablet without showing you the full agreement, stop.
Take the agreement home, review every page, and ask for changes in writing. Do not sign incomplete forms or allow a salesperson to fill in missing prices, dates, equipment, or incentives after you sign.
A practical verification checklist
- Mark the federal-credit claim. If the proposal promises a residential clean energy credit for a new installation, ask how it complies with the December 31, 2025 end date and request the supporting IRS authority.
- Identify every nonfederal incentive. Record the official program name, administrator, award calculation, funding status, deadline, ownership rule, and required documents.
- Call the utility. Confirm interconnection, system limits, tariff, export rate, bill-credit rules, fixed charges, and approval timing.
- Normalize competing bids. Give each bidder the same usage history and require system size, production, total installed price, fees, and guarantee terms.
- Verify the contractor. Check licensing, bonding, complaint history, subcontractors, insurance, and who will perform roof and electrical work.
- Map ownership. Write down who owns the equipment, receives incentives, maintains it, owns environmental attributes, and handles repairs.
- Calculate total obligations. Add cash price or all loan payments, lease or PPA escalators, fees, maintenance, possible buyouts, and utility charges.
- Review exit and sale terms. Confirm cancellation deadlines, early termination, removal, transfer, refinance, and home-sale requirements.
- Confirm tax treatment. Keep receipts, installation records, contracts, permits, and incentive documents; use current IRS instructions for the relevant tax year and obtain professional advice for your circumstances.
Bottom line for a 2026 solar contract
The federal residential clean energy credit is not available for expenditures after December 31, 2025, and an installation completed later is treated by the IRS as a later expenditure even if you paid earlier. Any remaining state, local, or utility incentive must be verified on its own terms. Before signing, confirm the program directly, obtain the utility tariff in writing, compare complete bids, and understand who owns the system, receives incentives, carries maintenance duties, and pays when you move or end the contract.
