NYC Solar Property Tax Abatement: Eligibility, Costs, and Deadline

The NYC solar property tax abatement returns up to 30% of what you spend installing solar panels or battery storage, paid out as a credit against your property tax bill over four consecutive years. For systems placed in service between January 1, 2024 and January 1, 2034, the abatement equals 7.5% of eligible costs per year, capped at $62,500 annually or $250,000 total.¹ You claim it by filing Form PTA4 through the Department of Buildings, and the March 15 filing date controls which tax year your four years start in.

How Much You Actually Get

Three limits apply every year, and the smallest one governs:

7.5% of your eligible expenditures
$62,500
The property tax you owe that year

That third limit is the one that catches people. If your annual property tax bill is $4,000 and your calculated abatement is $6,000, you receive $4,000. The remaining $2,000 does not roll into next year. Unused abatement is simply lost.²

Older systems placed in service between 2014 and 2023 received a smaller benefit of 5% per year for four years, totaling 20%.³ Only the 30% figure applies to new projects going forward.

h2>Which Properties Qualify

The abatement is available to Class 1 (one- to three-family homes), Class 2 (multi-family residential), and Class 4 (commercial and industrial) properties within New York City. The system must be physically installed at the property.⁴

Some properties are shut out because they already receive other tax benefits. Buildings receiving ICAP, 421-a, 421-b, or 421-g benefits, or paying PILOTs (Payments in Lieu of Taxes), cannot claim the solar abatement.² Check your property’s current benefits before you spend money on engineering fees. This exclusion sweeps in a fair number of newer multifamily developments.

The abatement attaches to the tax lot, not the owner. So the benefit stays with the property if it changes hands during the four years.

Which Costs Count

Eligible expenditures include solar panels and related hardware, labor for on-site preparation and installation, and architectural or engineering services tied to the project. Solar parking canopy structures also qualify.⁴

Two things do not count. Interest and finance charges are excluded regardless of how you fund the project. And any expenditure paid with a federal, state, or local grant must be subtracted from your base. NYSERDA’s NY-Sun incentive is treated as a grant, so it reduces your eligible expenditures.⁴

Tax credits, tax abatements, tax exemptions, and tax rebates are different. Your eligible base is not reduced by any of those.³ Claiming a federal tax credit, for example, does not shrink your NYC abatement.

Battery Storage Now Qualifies

The program covers electric energy storage equipment alongside solar panels. You can install a battery with your solar array, or add one to an existing solar installation, and claim the abatement on the storage costs separately.¹ The same rules apply: materials, labor, and design costs qualify; grant-funded amounts and financing charges do not.

This matters for owners who went solar before 2024. The statute used to allow only one abatement per tax lot, and that restriction was lifted for systems placed in service on or after January 1, 2024 so that existing solar owners could add battery storage and receive a second abatement.¹

How to Apply

You apply by completing Form PTA4, the Property Tax Abatement Application and Agreement for Solar Electric Generating System. A New York State registered architect or professional engineer must certify the form, verifying that the system was installed according to approved plans.⁵

PTA4 asks for:

The DOB job number from your construction permit
System capacity in kilowatts
The placed-in-service date, which sets the starting year
An itemized breakdown of hardware, labor, and professional services
Utility interconnection status with Con Edison, or a statement that the system will not connect to the grid
Your certifying professional’s New York State license number and P.E. or R.A. designation⁵

Keep every invoice and receipt. The itemized costs on PTA4 drive four years of abatement math, and the Department of Finance can ask for supporting documentation.

The information is submitted through DOB NOW: Build as part of your solar job filing. When the Department of Buildings issues the Letter of Completion, DOB NOW forwards the abatement information to the Department of Finance automatically.⁶

The March 15 Deadline

Applications filed by March 15 qualify for an abatement starting in the tax year that begins July 1 of that year. Miss the date and the abatement pushes to the following fiscal year.³ The four consecutive years run from that July 1 start.²

Because everything hinges on the Letter of Completion, timing is real money. If your install wraps up in February but the DOB sign-off drags into April, you lose a year. Make sure your installer and your certifying design professional understand this.

Condos, Co-ops, and Multi-Family Buildings

A condo or co-op roof is shared space, so the building’s board has to approve the project. That step often takes months. In condominiums, the abatement is divided among all tax lots within the building.⁷ A co-op is typically a single tax lot, so the abatement goes to the cooperative corporation and reaches shareholders indirectly through lower building expenses.

Individual unit owners cannot file on their own. The building owner or managing agent submits the application.

Landmarked Buildings and Historic Districts

If the property sits in a New York City historic district or is individually landmarked, the Landmarks Preservation Commission has to approve the installation before you build. LPC reviews solar proposals case by case, emphasizing minimal visibility from the street. Panels typically need to sit behind parapets or on roof sections that aren’t visible from public rights-of-way, installations must be reversible, and historic building materials cannot be damaged or removed.

None of that disqualifies you from the abatement, but it adds time and may cap your system size. A smaller array means a smaller abatement. Build the LPC review into your March 15 planning.

How This Stacks With Other Incentives

The federal Residential Clean Energy Credit under Section 25D, which covered 30% of solar costs for homeowners, expired on December 31, 2025.⁸ Homeowners placing a system in service in 2026 or later cannot claim it. That makes the city abatement the primary tax-side incentive for most residential projects, alongside any available NY-Sun rebate. Commercial owners in Class 4 may still have access to federal clean energy investment credits, but the amounts depend on project size, prevailing wage compliance, and apprenticeship rules; a tax professional familiar with Internal Revenue Code Sections 48 and 48E should review any commercial project.

NYSERDA’s NY-Sun incentive is applied by your contractor to reduce what you pay at installation. Households below 80% of area median income may qualify for additional support through NYSERDA’s Affordable Solar program.⁹ Remember that NY-Sun reduces your eligible expenditures for the city abatement because it counts as a grant.

One boundary worth flagging: New York State’s 15-year property tax exemption under Real Property Tax Law Section 487, which prevents solar from raising your assessed value, does not apply in NYC.¹⁰ The city opted out and offers this abatement instead.⁹ A solar installation in NYC could affect assessed value depending on how the Department of Finance treats the improvement.
