Roof and solar tax credits in 2026: What changed

If a salesperson applies a 30% federal credit to a roof, solar-shingle, panel, or home-energy project completed in 2026, ask them to remove it from the proposal. The federal homeowner credits discussed in older guides ended for new 2026 work.

The IRS FAQ on the 2025 law changes gives two different termination rules:

• Section 25C, Energy Efficient Home Improvement Credit: no credit for property placed in service after December 31, 2025.
• Section 25D, Residential Clean Energy Credit: no credit for expenditures made after December 31, 2025.

For Section 25D, paying a deposit or the full contract in 2025 does not preserve the credit when installation finishes in 2026. The IRS says the expenditure is treated as made when original installation is completed. For construction or reconstruction, it is tied to when the taxpayer’s original use begins.

This article provides general federal timing and verification guidance. It is not personalized tax advice, and the law, your facts, and tax-year instructions control.

The 2026 federal answer by project type

Project completed or placed in service in 2026	New federal homeowner credit	Why
Reflective or “cool” roof	No Section 25C credit	Section 25C ended for property placed in service after December 31, 2025
Insulation, windows, doors, or qualifying HVAC	No Section 25C credit	Same termination rule, even though eligible 2025 property categories differed
Conventional residential solar panels	No Section 25D credit	Section 25D expenditures after December 31, 2025 are disallowed
Solar roofing tiles or shingles	No Section 25D credit	A 2026 completed installation is a post-deadline expenditure
Battery storage for a residence	No new Section 25D credit	The same Section 25D termination applies

The answer is about these federal homeowner provisions. It does not decide eligibility for a state tax credit, property-tax treatment, local rebate, utility incentive, builder provision, or business credit.

Historical rules versus current rules

Many pages and proposals still repeat Inflation Reduction Act timelines that were correct before the 2025 law accelerated termination. Keep the tax year attached to every claim:

Claim you may encounter	Historical context	Correct use in 2026 planning
“Residential solar receives 30%”	The 2025 Form 5695 instructions state a 30% Section 25D rate for eligible property placed in service in 2022 through 2025	Do not subtract 30% from a system completed in 2026
“Solar shingles count even though they are roofing”	For eligible pre-deadline projects, the IRS distinguished solar-collecting shingles or tiles from decking, rafters, and traditional roofing that only served structural or roof functions	A qualifying product category does not override the December 31, 2025 cutoff
“Section 25C runs through 2032”	That was the earlier IRA schedule used by many guides	The later law ended Section 25C for property placed in service after December 31, 2025
“Paying in 2025 locks in Section 25D”	Payment timing alone may appear persuasive in a sales estimate	The IRS specifically says a post-2025 completed installation is treated as a post-deadline expenditure

The old version of this page incorrectly described cool-roof products as receiving a 30% Section 25C credit through 2032. Do not rely on that claim for any 2026 purchase. The IRS’s 2025 list of Section 25C improvements focused on items such as insulation, exterior openings, specified HVAC equipment, electrical enabling property, and home energy audits—not a general federal cool-roof credit.

What about a project completed in 2025?

A genuinely completed 2025 project is a tax-year 2025 question, not a 2026-project exception. Keep the contract, invoices, proof of payment, installation and inspection records, permission-to-operate documents where relevant, manufacturer information, and the version of Form 5695 instructions for the return being filed.

The 2025 instructions also discuss carrying an unused Section 25D amount into 2026. That is different from claiming a new credit for 2026 expenditures. Section 25C and Section 25D have different eligibility, limits, and carryforward rules, so do not transfer language from one credit to the other.

If completion date, original use, carryforward, home use, ownership, or cost allocation is uncertain, take the documents to a qualified tax professional. A contractor can document scope and dates; the contractor should not make a personalized federal tax determination for you.

Roof cost and solar cost are not automatically the same tax basis

For eligible pre-deadline Section 25D projects, the IRS explained that solar roofing tiles and shingles could qualify when they served as solar electric collectors as well as roofing. Traditional roof components that served only roofing or structural functions—such as decking or rafters—did not qualify merely because solar was installed above them.

That historical distinction still matters when reviewing a 2025 invoice or carryforward. It does not reopen the credit for a 2026 installation. Ask for separate line items for:

• Energy-producing equipment
• Non-energy-producing roof covering
• Decking and structural work
• Electrical and interconnection work
• Battery equipment
• Labor allocated by scope

State, local, and utility programs may still help

Federal termination does not automatically end another government’s or utility’s program. A property may still encounter rebates, state tax credits, renewable energy certificates, property-tax treatment, financing programs, or utility incentives.

Start with the Database of State Incentives for Renewables & Efficiency, then verify the result on the administering agency’s or utility’s current page. Database entries help with discovery; the live program rules and approval control.

Never assume a program applies because a neighboring homeowner received it. Eligibility may depend on:

• Property address, utility territory, and customer class
• Existing home versus new construction
• Product certification, system size, or contractor eligibility
• Purchase, lease, loan, or third-party ownership
• Preapproval before contract or installation
• Application, inspection, interconnection, or permission-to-operate date
• Funding availability, waitlists, and program caps
• Whether one incentive reduces the eligible cost for another

Incentive-verification checklist

Complete this checklist before treating an incentive as part of the budget:

1. Name the program and administrator. Record the official program page, not a contractor summary or search snippet.
2. Confirm the program is open. Check the current date, funding status, reservation window, and deadline.
3. Verify the property. Confirm address, utility, rate class, ownership, and primary-residence rules where applicable.
4. Verify the equipment and contractor. Record model numbers, certifications, capacity limits, and installer requirements.
5. Identify the controlling date. Determine whether application, contract, purchase, installation, inspection, interconnection, or placed-in-service date controls.
6. Get preapproval if required. Do not begin work or make a nonrefundable payment first when the rules prohibit it.
7. Separate estimated and approved amounts. Put an unapproved incentive in a contingent column, not in the guaranteed net price.
8. Check ownership and tax interaction. Confirm who receives the incentive and whether it changes basis or another benefit.
9. Save evidence. Keep the rules, approval, contract, itemized invoices, permits, inspection, interconnection, and payment records.
10. Recheck before filing. Use the final tax-year form and instructions, and ask a qualified tax professional about your facts.

Red flags in a 2026 proposal

Pause the sale when you see:

• “30% federal credit” deducted from the advertised 2026 price
• “Net cost” without the program name, eligibility owner, and approval status
• A credit calculated on the entire roof without cost allocation
• A claim that a 2025 payment preserves Section 25D despite 2026 installation
• A state or utility rebate described as automatic
• Advice to change a completion or placed-in-service date on paperwork
• A monthly-payment comparison that hides the cash price and total of payments

Bottom line

For new work completed or placed in service in 2026, budget the project without a new federal Section 25C or Section 25D credit. Verify any state, local, or utility benefit independently, keep it contingent until approved, and preserve the official rules and project records.

If your facts cross the 2025 deadline or involve a carryforward, use the correct Form 5695 materials and obtain tax advice before filing. A clear documented answer is worth more than an attractive after-credit price that the 2026 rules do not support.
