Is there a federal residential solar tax credit in 2026?

No for property placed in service after December 31, 2025, according to the IRS Residential Clean Energy Credit page current when this guide was verified.

Does that mean every solar incentive ended?

No. State, utility, local, business, and income-qualified programs are separate. Verify the specific program, eligibility, funding status, and deadline with its administrator.

Should a proposal still show the old credit for comparison?

A historical scenario can be labeled as such, but the decision case for a 2026 residential installation should not count an unavailable credit as money the homeowner will receive.

Solar Tax Credit 2026: The Federal Residential Credit Ended

A 2026 proposal should not build homeowner savings around a federal residential credit that is no longer available.

Published by Solar Quote Checker Editorial Team · Last verified July 23, 2026

The IRS says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025. That makes the tax line on a 2026 proposal a first-order quote check, not a footnote.

This page covers the federal homeowner credit only. State, utility, business, or other tax programs use different rules and must be verified independently.

What changed for residential solar in 2026

Eligible residential clean-energy property placed in service from 2022 through 2025 could qualify for a 30% credit under the federal program. The IRS now states that the credit is unavailable for expenditures made after December 31, 2025.

A proposal created in 2026 may still show older savings language or software defaults. Ask the installer to produce a version with the unavailable federal homeowner credit removed before comparing price, payback, or monthly savings.

Three numbers to recalculate on a 2026 quote

Removing a tax credit can change the displayed net cost, the assumed loan paydown, and the estimated payback period. Those figures should be recalculated together rather than deleting one line from a sales summary.

Net project cost after every incentive shown in the proposal.
Loan balance and payment if the model assumes a tax-credit lump-sum payment.
Payback and lifetime savings using only incentives the household can document.

What to ask the installer and tax adviser

Ask the installer to identify the legal name, eligibility rule, amount, expiration date, and source for every incentive. Ask a qualified tax professional about the household's own facts; an installer should not present a generic tax assumption as personalized tax advice.

Keep the signed contract, itemized invoice, permission-to-operate records, and any incentive application documents. If a state or utility benefit is claimed, verify it on the administering agency's current website before signing.
