Keuka Lake Property Taxes: Assessments, STAR & Grievance Guide

Last reviewed: October 9, 2026. General information only, not tax or legal advice. Rates, exemptions, and deadlines change every year and vary by town, village, and school district. Confirm with your assessor, tax collector, and the NYS Department of Taxation and Finance.

Property taxes come up in nearly every conversation about owning on Keuka Lake. The comparisons people trade at the marina are usually useless, because two houses a mile apart can sit in different towns, different counties, and different school districts. Each of those sets its own budget, and each town can assess at a different percentage of market value.

This guide covers how the system works around the lake: who taxes you, how assessments and equalization rates turn into a bill, the STAR credit, how to grieve an assessment (including the extra rights non-resident owners have), and the taxes you’ll see at closing. It’s the in-depth companion to our shorter overview, Property Taxes Around Keuka Lake, and part of our Property Taxes section.

Who taxes a Keuka Lake property

Keuka Lake lies in two counties. The northern half is in Yates County: the towns of Jerusalem, Milo, and Barrington, plus the Village of Penn Yan. The southern half is in Steuben County: the towns of Pulteney, Urbana, and Wayne, plus the Village of Hammondsport. A typical property tax picture has several layers:

County tax
Town tax (rates can differ inside and outside a village)
School district tax, usually the biggest single piece. Districts don’t follow town lines, so neighbors can be in different districts.
Village tax, if the property is inside Penn Yan or Hammondsport
Special district charges, such as fire, lighting, water, or sewer, depending on location

Bills are separate, and they arrive at different times of year. Yates County’s tax tips for property owners say school tax bills go out in September and are paid to the school tax collector, while town and county bills go out in January and are paid to the town tax collector through March 31, then to the county. Village taxes have their own schedule. Steuben County properties follow that county’s calendar, so confirm dates with your town tax collector.

Escrow note: if your lender escrows taxes, make sure it has the right school district and tax collector. On a newly bought lake property, a bill sent to the previous owner is a common first-year mix-up.

How the bill is calculated

The NYS Department of Taxation and Finance describes the formula simply:

Taxes owed = taxable assessment × tax rate per $1,000

Taxable assessment is your assessed value minus any exemptions you’ve been granted.
The tax rate comes from the levy. Each jurisdiction adopts a budget, subtracts revenue from other sources, and divides what’s left (the levy) by the total taxable assessed value in the jurisdiction.

The state lists what can change your bill from year to year: budgets, other revenue, the total taxable assessed value in the jurisdiction, how the levy is split among municipalities, and changes in your own assessment or exemptions. A neighbor’s new house can shift the math, and so can a town reassessment or a school budget vote.

Why comparing tax rates between towns misleads people

New York lets each town assess at its own level of assessment. Some towns assess at full market value and some don’t. The state measures each town’s level with an equalization rate: total assessed value divided by total market value. A rate of 100 means assessments equal market value. A rate below 100 means assessments are below market value (NYS explanation).

Two consequences for buyers:

You can’t compare a tax rate in one town with a rate in another unless both are at full value. A town with a low level of assessment will show a higher rate per $1,000 of assessed value.
Counties and school districts use equalization rates to divide their levies among towns. That’s how a school district spanning several towns charges each town a fair share.

The useful number is the actual current bill, or the property’s assessment adjusted to full market value. To check whether an assessment is fair, divide it by the town’s equalization rate (or by the residential assessment ratio, which the state publishes for grievance purposes). That gives you the market value the town is implying. Then compare it to what similar properties have sold for.

Lakefront assessments

Lakefront and lake-access homes are usually assessed higher than similar homes inland. Frontage, view, and water access are value factors, so that’s expected. What’s worth watching:

Frontage and land value. Make sure the tax record shows the right lot size and frontage. Shoreline footage on the tax map also decides how many docks you can have; see our dock rules guide.
Improvements the assessor may not know about. Finished basements, winterized porches, and new docks can change values. Unpermitted work can cause trouble later.
The sale itself. The state’s new homebuyer guidance recommends using the Sales Web tool in its Municipal Data Portal to look up comparable sales. It also recommends asking the assessor for a tax estimate before you buy.

The STAR credit and exemption

New York’s School Tax Relief (STAR) program lowers school taxes on a primary residence. It comes in two forms (NYS eligibility page):

STAR credit: a check or direct deposit from the state. This is what new homeowners get.
STAR exemption: a reduction on the school tax bill. It’s only available to people who’ve had it on the same home since 2015. “The STAR exemption is no longer available to new homeowners.”

And two benefit levels:

Basic STAR: no age requirement. Combined income of the owners and their resident spouses must be $500,000 or less for the credit ($250,000 or less for the exemption).
Enhanced STAR: at least one resident owner must be 65 or older by December 31 of the benefit year. For 2026 benefits, the income limit is $110,750, and for 2027 benefits it’s $113,550. For STAR, “income” means federal adjusted gross income minus the taxable part of IRA distributions, using the return from two years earlier.

STAR and second homes

STAR only applies to a primary residence. The state looks at how much time you spend there, where you’re registered to vote, and the address on your vehicle registration and ID. A married couple can get only one STAR benefit, no matter how many homes they own. If you’re turning a seasonal Keuka cottage into your year-round home, register once it actually becomes your primary residence.

How to register

The Tax Department says that once the home becomes your primary residence, you register for the STAR credit online through its Homeowner Benefit Portal (in your Individual Online Services account). Depending on when you bought, you may get the prior owner’s STAR exemption in your first year instead of the credit. After that, the credit arrives each year as long as you’re eligible.

Other exemptions to ask about

Besides STAR, most property tax exemptions in New York are local options. Each county, town, and school district decides whether to offer them and sets some of the terms. Common ones include senior citizen exemptions with income limits, veterans’ exemptions, and exemptions for people with disabilities. The state’s guidance is to check with your assessor about what your community offers. Deadlines matter. Many exemptions have to be filed by the taxable status date (often March 1), so ask early.

How to grieve your assessment

If your assessment looks too high, New York has a free process that doesn’t require a lawyer (NYS grievance procedures):

Check the tentative roll. Only the assessment on the current tentative roll can be challenged. Tentative Roll Date is May 1 in most communities.
File Form RP-524 (Complaint on Real Property Assessment) with the assessor or the Board of Assessment Review (BAR).
Meet the deadline. In most towns, the deadline and the BAR hearing are both on Grievance Day, usually the fourth Tuesday in May. Confirm the date with your assessor or clerk. Towns that share an assessor can set a date between the fourth Tuesday in May and the second Tuesday in June. Villages that do their own assessing typically hold grievance day in February. A mailed form has to arrive by Grievance Day, and missing the deadline costs you both administrative and court review for that year.
Bring evidence: recent sales of comparable properties, an appraisal, and corrections to the property description, such as wrong square footage, frontage, or condition.
If you’re still not satisfied: owners who live in their own one-to-three-family home can use Small Claims Assessment Review (SCAR). The filing fee is listed as $30. Other owners file a tax certiorari case. Both must start within 30 days of the final roll being filed.

Extra rights for non-resident owners

Many Keuka owners live somewhere else part or all of the year. The state gives non-resident owners two useful rights:

You can make a written request for a list of your property, its assessed value, and the time and place of grievance hearings. The request has to be made at least 15 days before Tentative Roll Date, and the assessor must mail the information within five days after the tentative roll is finished.
You can ask for a hearing date after Grievance Day, up to 21 days later. You still have to submit RP-524 on or before Grievance Day.

You can also stipulate, meaning agree with the assessor on a reduced assessment, on or before Grievance Day. Once you sign a stipulation, you can’t ask for a further reduction that year.

Taxes you’ll pay at closing

Beyond annual property tax, buyers and sellers should know about these New York charges (Tax Department: new homebuyers and real estate transfer tax):

Real estate transfer tax: $2 for each $500 of consideration, generally paid by the seller.
“Mansion tax”: an extra 1% on residential property sold for $1 million or more, generally paid by the buyer. It applies statewide, and plenty of Keuka lakefront sells above that price.
Mortgage recording tax on financed purchases.
A filing fee for the Real Property Transfer Report (Form RP-5217).

Your attorney and title company will calculate the exact amounts.

A practical tax checklist for buyers

Get all current bills: county, town, school, and village. Don’t rely only on the listing’s “taxes” figure.
Find out which school district the parcel is in and look up its budget history.
Ask the assessor whether the town has had a recent reassessment and what its equalization rate is.
Check the assessment record for errors in frontage, acreage, square footage, and improvements.
Find out which exemptions the seller receives (STAR, senior, veteran). Those go away when the property changes hands, so your bill may be higher.
Plan your STAR registration if this will be your primary home.
Note Grievance Day and the tentative roll date on your calendar.

Frequently asked questions

Are property taxes higher on Keuka Lake?

Lakefront properties usually have higher assessed values, so their bills tend to be higher. But school district, town budgets, and the town’s level of assessment matter a lot. Compare actual bills, not rates.

Can I get STAR on a lake house that’s my second home?

No. STAR only applies to an owner’s primary residence, and a married couple can receive only one STAR benefit.

What is the income limit for Enhanced STAR?

For 2026 benefits it’s $110,750, and for 2027 benefits it’s $113,550. That’s combined income of the owners and their resident spouses, measured as federal AGI minus taxable IRA distributions. At least one resident owner must be 65 or older.

When is Grievance Day around Keuka Lake?

In most New York towns it’s the fourth Tuesday in May. Towns that share an assessor and villages that assess may use other dates. Always confirm with your assessor.

I’m not a full-time resident. Can I still grieve?

Yes. Non-resident owners have extra rights, including asking for assessment information before the tentative roll and requesting a hearing up to 21 days after Grievance Day. You still have to file on time.
