On January 1, 1991, the Village of Nyack disbanded its own police force, and something unusual happened: the department didn't just close down, it split in half. Because the village sits inside two different towns, state law required each town to absorb the officers who policed its portion. The eastern half of the village, including the entire downtown business district, went to the Town of Orangetown. The western half went to the Town of Clarkstown. Ten officers and two sergeants landed on one side of an invisible line that runs through the middle of a single village most people think of as one place.
That line didn't go away when the patrol cars changed decals. It's still there, and it still governs which office assesses your home, which board hears your tax grievance, and, if two pending pieces of local legislation move forward, how much you might owe at closing on top of the taxes New York State already collects.
A village with two landlords
The Village of Nyack's own website introduces itself simply: it describes the village as located in the Town of Orangetown within Rockland County. That's accurate for most of the village, and it's also incomplete. A small western section of the incorporated village actually sits in the Town of Clarkstown, a fact the village's own page doesn't mention. Reference sources are split on how to describe it too: Wikipedia calls Nyack a village primarily in Orangetown with a small western section in Clarkstown, while Britannica describes it more evenly as a village in the towns of Clarkstown and Orangetown.
The confusion isn't a modern branding problem. It goes back to 1990, when the Village of Nyack passed a local law giving up its own authority to assess property. Instead of maintaining its own tax rolls, the village chose to let two separate town assessors do that work for it, with taxes levied using whichever town's roll matched each parcel's physical location. That single decision is why, three decades later, a house on one block of the village can carry an assessed value calculated by an assessor in Orangetown, while a house a few streets over carries one calculated by an assessor in Clarkstown, using a different Residential Assessment Ratio entirely. Clarkstown's 2025 ratio, for instance, sat at 19.44 percent, a figure that has nothing to do with what Orangetown uses for the parcels it assesses inside the same village.
What the split changes today
None of this shows up on a listing sheet. It shows up in the paperwork after you're under contract, which is exactly when you don't want a surprise.
| Orangetown-side parcel | Clarkstown-side parcel | |
|---|---|---|
| Assessing authority | Town of Orangetown assessor | Town of Clarkstown assessor |
| Residential Assessment Ratio | Set independently by Orangetown | 19.44% for 2025, set independently by Clarkstown |
| Village tax billed | June, per the village fiscal calendar | June, same village calendar |
| State, county, and town tax billed | January | January |
| School tax billed | September | September |
The billing calendar lines up because both parcels sit in the same village and the same school district, Nyack Union Free School District, which itself spans parts of Orangetown and Clarkstown and feeds into one high school. What doesn't line up is the number underneath that calendar. Two houses that would sell for the same price on the open market can carry different assessed values simply because two different offices, using two different ratios, decided what "assessed value" means for each of them. A tax bill built on that number can diverge even when the headline school tax rate is identical for both properties, because the rate is only half the equation. The assessed value is the other half, and that's the part the town line quietly controls.
If you believe your assessment is too high, Rockland's towns have historically set Grievance Day on the fourth Tuesday in May, and the 2026 assessment review deadline for Nyack parcels has been reported as May 26, 2026. But because the two halves of the village report to different assessing offices, a grievance for a Clarkstown-assessed parcel and a grievance for an Orangetown-assessed parcel are two separate filings, heard by two separate Boards of Assessment Review, even though both properties have a Nyack mailing address and sit inside the same village limits.
"We're almost 7,000 residents strong living along the Hudson River just north of the Mario M. Cuomo Tappan Zee Bridge, located in the Town of Orangetown within Rockland County."
That's how the village describes itself to visitors, and it's not wrong, it's just not the whole map.
The line is about to get more expensive
Here's the part that matters most if you're closing in the next year or two. Both towns that share the Village of Nyack are separately building their own real estate transfer tax, and as of this writing, neither one is fully in effect.
Orangetown's Town Board adopted Local Law 3-C on July 14, 2026, creating a 0.3 percent transfer tax on real property conveyances, paid by the purchaser, with revenue earmarked for a Community Preservation Fund aimed at open space, historic resources, and working farms. The law exempts the first $100,000 of value on improved property and the first $50,000 on unimproved land. But the tax can't actually be collected yet. New York's community preservation fund statute requires a mandatory town-wide referendum before collection begins, and Orangetown has targeted that vote for November 2026.
Clarkstown is a step behind. State legislation authorizing Clarkstown to create its own preservation fund and impose a transfer tax of up to 0.75 percent passed the legislature, but as of this summer it still needed the Governor's signature. After that, Clarkstown would still need to hold its own public hearing, pass its own local law, and put the question to its own voters in a future referendum, a process Orangetown is already partway through.
Neither tax replaces what New York already collects. The state's existing transfer tax runs $2 for every $500 of value, or 0.4 percent, and adds a 1 percent mansion tax on residential sales of $1 million or more. Given how much of the current Nyack-area inventory this brand sees sits at or above that $1 million mark, a future local transfer tax wouldn't be a replacement cost, it would stack directly on top of the state tax and the mansion tax that already apply.
The practical result: a buyer closing on the Orangetown side of the village after a November 2026 referendum passes could owe a local transfer tax that a buyer closing the same month on the Clarkstown side does not, simply because Clarkstown's process is further from the finish line. That gap could close, or it could widen, depending on how each referendum and each town's timeline plays out.
What to ask before you sign
- Ask the listing agent or attorney which town's assessor currently holds the parcel's assessment roll. It's a one-line answer they should be able to confirm.
- If a grievance is part of your post-purchase plan, confirm which Board of Assessment Review has jurisdiction and what that board's current-year deadline is, rather than assuming it matches a neighbor's timeline.
- Ask your attorney to check the status of both towns' Community Preservation Fund transfer taxes at the time you go to contract, not at the time you first toured the house. Orangetown's referendum outcome and Clarkstown's legislative progress can both move between an accepted offer and a closing date.
- If the property sits near the village's western edge, don't assume "Nyack" on the listing means Orangetown. Confirm it directly.
A few questions worth asking before you close
Does this affect Upper Nyack or South Nyack too? No. Upper Nyack is a separate incorporated village entirely within Clarkstown, and South Nyack is a separate incorporated village entirely within Orangetown. The split described here is specific to the Village of Nyack itself, the only one of the Nyacks that straddles both towns.
Does the town split change my school tax rate? Not the rate. Nyack Union Free School District sets one levy for the district regardless of which town collects it. What can still differ is the assessed value the levy gets applied to, since that value comes from whichever town's roll covers your specific parcel.
How do I find out which town my address falls under right now? Ask your attorney or agent to pull the parcel's tax map identification, which will show the assessing town directly, rather than relying on the mailing address or the village name alone.
A village that looks like one place on a map can still operate as two jurisdictions underneath it, and the only way to know which one applies to a specific house is to ask before you're locked into a contract. If you're comparing homes across the Nyack line, or anywhere else in the Lower Hudson Valley or Bergen County, Bobbie Procida can walk through exactly what applies to the property you're looking at, town by town, before you sign anything. Schedule a consultation to get the specifics for your address, not just the general map.
