NYC Tax Abatements Guide in New York (2024)
Go Back To Previous PageQuick answer: An NYC tax abatement reduces your property tax bill for a set number of years, usually tied to new construction or major renovation — the two big names are 421a and J-51. Important update: 421a stopped accepting new applications in June 2022 and was replaced by 485-x (Affordable Neighborhoods for New Yorkers) in 2024. If you’re buying into an older building with an existing 421a abatement, it continues on its original schedule (some run through 2042–2045) — you’re just not getting a brand-new one on new construction anymore.
If you’ve been apartment hunting in NYC, you’ve probably seen “421a abatement” or “tax abated” in a listing and wondered whether that’s marketing or math. It’s math — and it’s often the difference between a monthly tax bill that’s manageable and one that quietly triples the year the abatement ends, at which point the listing agent who sold you the place has, coincidentally, moved on to other clients.
Here’s what’s actually available in 2026, what changed, and how to verify any abatement before you sign anything, rather than after your first “fully taxable” bill arrives like a surprise party nobody wanted.
Tax Abatement vs. Tax Exemption: What’s the Difference?
A tax abatement is a temporary reduction in the property tax owed, typically granted to encourage new construction or renovation in a specific area.
A tax exemption reduces your tax bill based on who you are — your income, age, or veteran status, for example — rather than what was built.
Abatements are about the building; exemptions are about the owner. NYC has both, and buyers often confuse the two because listings rarely bother to distinguish them.
421a: Still the Most-Discussed Abatement, But Closed to New Construction
The 421a program began in 1971. It encouraged developers to build multi-unit residential buildings. For decades, it was the abatement you were most likely to see in a listing. Two things are true about it at once in 2026:
- New 421a applications stopped in June 2022. No new building can apply for 421a today — the program’s successor, 485-x (Affordable Neighborhoods for New Yorkers), took over in April 2024 and applies to projects that broke ground after June 16, 2022.
- Existing 421a abatements keep running. If a building already has 421a, it continues on its original term — some run through 2042–2045 — regardless of the program’s closure to new applicants.
This matters a lot to buyers. An older building’s 421a abatement is a real asset. It can be verified. It also has a clear expiration date. A brand-new building cannot have 421A at all — full stop, no matter how convincingly the floor plan is lit. If a listing implies otherwise, that’s your cue to verify directly rather than take the listing’s word for it.
421a Term Lengths and Codes
- 10-year term (Code 5110, 5117)
- 15-year term (Code 5113, 5118)
- 20-year term (Code 5116)
- 25-year term (Code 5114)
421a Phase-Out Schedule
The abatement starts at 100% and steps down over the final years of the term rather than dropping off a cliff:
| Benefit Year | 10-Year Term | 15-Year Term | 20-Year Term | 25-Year Term |
|---|---|---|---|---|
| 1–2 | 100% | 100% | 100% | 100% |
| 3–4 | 80% | 100% | 100% | 100% |
| 5–6 | 60% | 100% | 100% | 100% |
| 7–8 | 40% | 100% | 100% | 100% |
| 9–10 | 20% | 100% | 100% | 100% |
| 11 | Fully Taxable | 100% | 100% | 100% |
| 12–14 | — | 80%→40% | 100% | 100% |
| 15 | — | 20% | 100% | 100% |
| 16 | — | Fully Taxable | 100% | 100% |
| 17–20 | — | — | 80%→20% | 100% |
| 21 | — | — | Fully Taxable | 100% |
| 22–25 | — | — | — | 80%→20% |
| 26 | — | — | — | Fully Taxable |
Before you sign a purchase agreement, ask your real estate attorney to confirm the unit’s abatement year. A tax-abated unit in year 9 of a 10-year term can cost much more than one in year 2.
J-51: The Renovation-Focused Abatement
J-51 is discussed less often than 421a, but it works in a similar two-part structure. It focuses on renovating older buildings or converting commercial spaces to residential use. It is not meant for new ground-up construction
- Tax exemption: the property’s assessed value is frozen at its pre-renovation level.
- Tax abatement: property taxes are reduced by a percentage of the “certified reasonable cost” of the renovation for a term of up to 34 years.
If a building was converted from commercial or industrial use, or underwent a major gut renovation, J-51 is the abatement to ask about rather than 421a.
The NYC Co-op & Condo Tax Abatement
Separate from both of the above, this abatement helps existing co-op and condo owners reduce their property taxes by 17.5%–28.1% annually, scaled by the unit’s assessed value:
| Assessed Value | Abatement |
|---|---|
| $50,000 or less | 28.1% |
| $50,001–$55,000 | 25.2% |
| $55,001–$60,000 | 22.5% |
| $60,001 or more | 17.5% |
To qualify, the unit must be your primary residence. You must buy it before January 5 of the tax year. You cannot own more than three units in the building. This is not a program for landlords building an empire. The unit also cannot already receive a J-51, 421a, or similar abatement.NYC allows one tax break at a time, not a buffet.
Eco-Friendly Abatements
NYC also offers abatements for green building features, independent of new construction status:
- Green roof abatement: a one-time tax abatement of $4.50 per square foot of vegetated roof space, capped at $100,000 or that year’s total tax bill, whichever is less.
- Solar roof abatement: a benefit for rooftop solar installations, though a unit already receiving 421a or similar new-construction abatements isn’t eligible to stack this on top.
Property Tax Exemptions (Based on Who You Are, Not What You Built)
STAR and Enhanced STAR
The School Tax Relief (STAR) exemption knocks a few hundred dollars off property taxes each year for owner-occupants below the income threshold. Enhanced STAR is for owners aged 65 and older.
It offers a larger benefit. For the 2026–2027 school year, the income limit is $110,750.
This is higher than in prior years. Do not rely on an old number from another guide. That includes an older version of this guide.
SCHE (Senior Citizen Homeowners’ Exemption)
SCHE is separate from STAR and stacks with it. Homeowners 65+ with a combined household income of $58,399 or less can get up to a 50% reduction in assessed value, scaled down on a sliding scale as income approaches the cap.
Veteran, Good Samaritan, and Clergy Exemptions
Smaller additional exemptions exist for military veterans, people disabled during or preventing a crime, and members of the clergy — amounts vary by situation. The full current list lives on the NYC Department of Finance benefits page.
How to Verify a Tax Abatement Before You Buy
Don’t take a listing agent’s word for it — “tax abated!” in a listing description is doing a lot of unverified work, and it costs you nothing to check. Verify independently on the NYC Department of Finance property tax lookup.
You’ll need the borough, building number, street, and apartment number. Once you’re in, click “Benefits — Business & Construction” to see current exemptions, the current tax period amount, and the proposed amount for the next period — which tells you exactly where the building sits in its phase-out schedule, not just whether an abatement technically exists somewhere in its past.
Tax Abatement FAQ
What is a tax abatement in NYC?
A temporary reduction in property taxes is usually granted to encourage new construction or major renovation. The two most common are 421a (largely legacy now) and J-51.
Is the 421a tax abatement still available?
Not for new construction — it closed to new applications in June 2022. Existing 421a abatements on already-built buildings continue on their original schedule. The current program for new construction is 485-x.
What’s the difference between 421a and J-51?
421a applies to new ground-up residential construction; J-51 applies to renovations and conversions of existing buildings. Both combine a tax exemption with a phased-in tax abatement.
How do I know when a building’s tax abatement expires?
Verify directly on the NYC Department of Finance’s property tax lookup tool using the building’s address, or have your real estate attorney confirm the exact benefit year during due diligence.
Can I combine multiple tax abatements or exemptions?
Generally, no for abatements tied to construction (a unit already receiving 421a can’t also get the co-op/condo abatement or solar abatement), but STAR and SCHE can be combined since they’re both owner-based exemptions rather than construction abatements.
The Bottom Line
A tax abatement can save you real money. But it only helps while it lasts.
A listing that says “tax-abated” means little. You need to know the program and the schedule year. You also need to know when it ends.
With 421a now closed to new construction and 485-x as its successor, that verification step matters more than ever. Nobody wants to fall in love with a monthly carrying cost that was only ever a temporary personality.
Working with someone who checks this before you fall for a listing’s monthly carrying-cost number is worth it — and NestApple pays buyers up to 2% back at closing, on top of that due diligence.
