New York State Tax Credit for Solar Panels in 2026

The New York State tax credit for solar panels is worth 25% of eligible expenditures, up to $5,000. For a qualifying 2026 purchase it remains available under current state law, even though the federal household credit does not apply to new installations completed after 2025. New York also permits qualifying long-term leases and PPAs, using different payment-based rules.

The federal residential clean energy credit under section 25D ended for expenditures made after 31 December 2025. The IRS timing FAQ (questions 1 and 7) explains the installation-completion rule and the separate construction/reconstruction rule. A qualifying 2025 installation may still support a 2025 claim and unused-credit carryforward; a 2025 deposit for an installation completed in 2026 does not preserve eligibility.

How the New York State tax credit for solar panels is calculated

For a qualifying purchase, the New York credit is the smaller of 25% of eligible expenditures or $5,000. This is a potential income-tax credit, not a discount on the installation invoice. The system must serve the taxpayer’s principal residence in New York; an eligible residence can be owned or rented. For electricity-generating equipment, the statutory net-metering requirements and completed utility connection also apply. See the official Form IT-255 instructions and New York Tax Law section 606(g-1).

At $20,000 of eligible expenditures, 25% reaches the $5,000 cap. Larger eligible purchase amounts do not increase that maximum. The cap alone is not a reason to increase a system’s size, and it does not establish how much credit a household can use.

The claim is made on Form IT-255, filed with the state return. The credit is nonrefundable: the amount used is limited by available New York State tax liability under the return’s calculation. An unused amount can be carried forward for the next five tax years, after which an unused remainder expires. Tax liability is different from the balance due after withholding or estimated payments; a person expecting a refund can still have tax liability. Do not show the full $5,000 as cash received now when a household’s usable credit has not been calculated.

Which costs enter the purchase calculation?

The official Form IT-255 instructions includes eligible solar equipment and properly allocated preparation and installation, architectural and engineering costs. Interest and financing charges are excluded, as are expenses paid with nontaxable grants. Keep the gross invoice, grant or incentive documents, and evidence of what you paid; exclude a grant-funded amount once rather than subtracting it again from an already net eligible figure. Do not treat every benefit labeled a rebate or tax credit as the same type of cost adjustment.

Ordinary roof replacement is not automatically an eligible solar equipment cost. Have any claimed allocation documented and checked. Solar equipment that generates electricity must also satisfy the state’s connection and net-metering requirements.

Which federal rules apply to your system, and why the date is not the switch-on

The One Big Beautiful Bill Act, signed on 4 July 2025, ended section 25D for expenditures made after 31 December 2025. New installations completed in 2026 do not receive a reduced or phased-down household credit.

For a normal equipment installation, the IRS treats the expenditure as made when the original installation is completed. A deposit, signed contract or advance payment in 2025 does not preserve section 25D for an installation completed in 2026. For an expenditure connected with construction or reconstruction of a structure, the IRS instead applies the date the taxpayer begins original use of that structure. See the IRS timing FAQ (questions 1 and 7). Utility permission to operate or a first bill credit, by itself, does not establish which timing rule or tax year applies.

A household paying cash or using a loan for a new installation completed in 2026 cannot claim section 25D for that expenditure. A 2025 installation must meet the historical eligibility rules before a credit can be claimed. The final 2025 Form 5695 instructions permit unused 2025 credit to be carried to 2026. That carryforward is not a credit for new 2026 costs.

If your project straddles that boundary, keep the contractor’s completion sign-off, inspection records, permit close-out, final invoice, payment evidence and utility records. These are evidence to review, not an automatic legal conclusion. A tax professional should determine which timing rule and year apply before you file.

What still applies in New York

The main routes discussed here are the New York income-tax credit, NY-Sun incentives when an eligible project receives approval, the NYC property-tax abatement for qualifying city buildings, and electricity-bill arrangements such as net metering. They affect different bills and have different eligibility rules.

NY-Sun is regional and program-specific. See the NY-Sun programme guide and NYSERDA’s regional dashboards. As checked on 7 October 2026, the regular residential NY-Sun blocks in the Con Edison, Upstate and Long Island regions are closed. The Con Edison and Upstate Affordable Solar blocks are also closed. However, the Affordable Solar intake accepts applications for PSEG Long Island customers, and the Long Island dashboard lists a conditional $0.40-per-watt Affordable Solar incentive. This does not establish remaining funding or an approved award for a particular project. Confirm income eligibility, current funding and contractor approval before including an incentive in a quote.

Who now gets the tax benefit, by arrangement

Ending the household section 25D credit does not establish whether a business owner qualifies for a separate federal investment credit. A third-party provider may have a business tax benefit under different eligibility rules and deadlines; this page does not determine that benefit.

A provider may reflect its own tax position in a lease or PPA price, but a household cannot assume the provider qualifies or that a tax saving is passed through. Compare the actual contract price, escalators, maintenance obligations and transfer terms rather than treating a provider’s potential credit as your own.

A qualifying written lease or power purchase agreement must run for at least ten years. New York has separate payment-based rules for these arrangements; the $5,000 cumulative limit is not a new $5,000 award every year, and payments after year 15 do not earn a new credit under an agreement longer than 15 years. The official Form IT-255 instructions and Tax Department lease/PPA guidance explain the calculations. The purchase formula below must not be applied to a lease or PPA. Have the agreement and payment calculation checked by a qualified tax professional; this page does not automate either calculation.

A purchase example: potential credit versus credit usable this year

Assume a system placed in service in 2026 at a New York principal residence, a completed qualifying utility connection, and $20,100 of fully eligible purchase and installation expenditures. Assume there are no grant-funded costs or financing charges in that amount.

The installation still costs $20,100 before tax benefits. A $15,100 cost after the full credit is only a conditional illustration if all $5,000 is eventually usable; it is not an upfront invoice price or guaranteed cash payment.

What this does to the arithmetic of buying

For the same installed price and energy assumptions, removing a previously available federal credit increases the after-tax purchase cost. A current comparison still needs the actual price and benefits available to that particular project.

The relevant variables include the installed price, any separately confirmed incentive, your electricity rate, on-site use and exports, financing costs, and the state credit you can actually use. Installed cost in New York is a useful starting point; do not use an unapproved incentive or the maximum tax credit as guaranteed cash savings.

Who can claim the state credit

The system must be at your principal residence in New York State when placed in service. A qualifying home may be owned or rented, but a second or vacation home does not meet the principal-residence requirement. An owner who does not live in a rented-out property cannot assume that property qualifies for this individual credit. Equipment, utility-connection and other IT-255 conditions also apply.

The value to a household depends on available tax liability in the claim year and the next five tax years. Two neighbours with identical systems can therefore use different amounts. See the credit basics guide and the official IT-255 instructions, and use the final form for the tax year being filed.
