Clean energy advice for New York homes, where the state credit outlived the federal one
New York is the only state we advise in where a homeowner who does not buy the system outright can still reach a state tax credit.
When the federal residential credit ended on 1 January 2026, most states left buyers with net metering and not much else. New York did not. Its own residential credit against state income tax carried on untouched — and it is written in a way that reaches people who lease as well as people who buy.
That single quirk makes New York the state where the ownership question is worth the most careful thought, and where advice written even a year ago is most likely to be out of date. Working through that comparison honestly is exactly the job.
New York at a glance
Twenty years of net metering
Interconnect today under Phase One and full retail crediting is locked in for two decades.
A state income tax credit
Claimed on your New York return — and available whether you buy or lease.
Fifteen-year property exemption
The added value is exempt under RPTL 487, if you file and your town has not opted out.
NY-Sun has narrowed
The standard-income rebate blocks have closed in several territories. Last year’s quote may assume money that is gone.
The New York credit that still reaches you if you lease
Almost every state incentive in the country is written for the system’s owner. When the federal residential credit ended, that is exactly why third-party ownership became the only route to a federal benefit — the leasing company owns the system and claims the commercial credit.
New York is the exception worth knowing about. Its residential credit is calculated on what you actually pay, so a homeowner on a lease or power purchase agreement can claim it against the payments they make each year, up to the same lifetime cap as a buyer. Very few states do this. It means the buy-versus-lease comparison in New York has to be run properly rather than assumed from a national rule of thumb, because both routes can carry a state benefit here.
Two New York filings, two different offices
| State income tax credit | Property tax exemption | |
|---|---|---|
| What it does | Reduces your state income tax | Excludes the added value from your assessment |
| Where it is claimed | Form IT-255, with your state return | Form RP-487, with your local assessor |
| The deadline | Your tax filing | Your municipality’s taxable status date |
| If you lease | Still available to you | Not applicable — you do not own it |
| Can your town opt out | No | Yes — some have |
NY-Sun narrowed, and a lot of advice has not caught up
NY-Sun is the state’s rebate programme, paid through declining megawatt blocks that close as they fill. For years it was a reliable line on a New York proposal, and plenty of material still online treats it that way.
It is no longer that simple. The standard-income blocks have closed in major territories, with remaining availability directed at lower-income households. A homeowner working from a quote or an article written a year ago can easily be expecting a rebate that no longer applies at their address and income. Checking the current block status where you live is a five-minute job that changes the arithmetic, and it is one of the first things we do.
Your utility decides which crediting scheme you are on
Con Edison, National Grid, NYSEG, RG&E, Central Hudson, Orange & Rockland and PSEG Long Island
New York’s major utilities offer full retail crediting to residential solar customers under Phase One net metering, and a system interconnected today keeps that treatment for twenty years. Territories differ enormously in rates, rebate block status and how quickly interconnection moves — Con Edison’s New York City and Westchester service area behaves very differently from upstate National Grid.
Net metering or VDER — which one applies to you
Most homes stay on Phase One net metering, which credits exports at the full retail rate. Larger systems and community solar move to the Value of Distributed Energy Resources tariff, which values energy by when, where and how cleanly it was produced rather than at a flat retail rate. For a typical house the choice is usually straightforward; it is worth confirming rather than assuming.
The Customer Benefit Contribution
New York solar customers pay a monthly Customer Benefit Contribution charge, and it is set slightly higher under net metering than under VDER. It is a small number and it does not change the conclusion for most homes — but it belongs in an honest calculation, and it is the sort of line that gets left out of an optimistic proposal.
The order we recommend in New York
New York rewards getting the paperwork right as much as getting the hardware right. Our recommended sequence:
- Confirm your utility and your NY-Sun block status — both vary by territory and one of them may have closed
- Check whether your municipality opted out of RPTL 487 — the property tax exemption is not universal
- Run buy versus lease properly — New York is the state where leasing does not automatically forfeit the state credit
- File both forms — IT-255 with your return, RP-487 with the assessor before the taxable status date
From Long Island to the North Country, one state is really several
New York asks more of a site assessment than anywhere else we work. In New York City and Westchester the constraints are roof access, building rules and shading from neighbouring structures. On Long Island it is coastal exposure. Through the Hudson Valley it is mature tree canopy on wooded lots.
Upstate the whole equation shifts again: shorter winter days, real snow load, and a heating season long enough that the building envelope often deserves attention before the roof does. A recommendation that works in Queens is not the recommendation for Syracuse, and we do not pretend otherwise.
The services New York homeowners ask us about most
Battery and backup
Ice storms upstate and grid stress downstate produce the same question. Storage decides what stays on and for how long. Explore storage
Roofs and efficiency
New York has a lot of old housing. Where the roof is near its end, sequence replacement before mounting, with detach and reattach if an array is already up there.
Charging and control
With twenty years of net metering locked in, shifting load is about comfort and capacity rather than rate arbitrage. Home EV charging and smart controls handle it quietly.
New York questions we hear most
Does the state tax credit really apply if I lease?
Yes — and it is unusual. New York calculates the residential credit on what you actually pay, so lease and power purchase agreement payments can qualify, up to the same lifetime cap that applies to a purchase. It is the main reason the ownership comparison in New York does not follow the national pattern.
Is the NY-Sun rebate still available?
Not in the way it once was. The standard-income blocks have closed across major territories, with remaining capacity aimed at lower-income households. We check current block status for your address rather than quoting a figure from an article.
Will my property taxes go up because of the panels?
Under RPTL 487 the added value is exempt for fifteen years — but you have to file Form RP-487 with your assessor, and municipalities are allowed to opt out of the exemption. Both are worth checking before you sign anything.
How long does net metering last?
A system interconnected today under Phase One keeps full retail crediting for twenty years. That is a long horizon, and it is one of the strongest arguments for not deferring a decision indefinitely.
If you are weighing solar, storage or an efficiency upgrade anywhere in New York, tell us your utility, your municipality and roughly what you pay. We will tell you which incentives actually reach you, and whether buying or leasing serves you better here.
