How to Appeal Your Putnam County Property Tax Assessment

To appeal a Putnam County property tax assessment, you confirm your assessed value is higher than your home’s market value, talk to your town assessor, then file Form RP-524 with the town’s Board of Assessment Review by Grievance Day, the fourth Tuesday in May. If the Board denies you or offers too little, you have 30 days after the final assessment roll is filed on July 1 to take the case to court.

Putnam County has six towns (Carmel, Kent, Patterson, Philipstown, Putnam Valley, and Southeast) and three villages (Brewster, Cold Spring, and Nelsonville), each with its own assessor who sets values for every parcel.¹ Those valuations drive your municipal, county, and school tax bills, so an inflated assessment means you’re overpaying across all three.

First, Confirm Your Assessment Is Actually Too High

Before you file anything, do the math. If your town assesses at 100 percent of market value, as Southeast does using a July 1 valuation date,² compare the assessed value on the tentative roll directly to what your home would sell for today. Pull recent sales of similar homes nearby. If they consistently close below your assessed value, you have a case.

If your town assesses at less than full market value, you need the equalization rate. Divide your assessed value by the equalization rate to get the market value the assessor effectively assigned. A property assessed at $200,000 in a town with an 80 percent equalization rate carries an implied market value of $250,000.³ If comparable homes are selling for $220,000, the assessment is too high. The 2026 tentative rolls for all six towns are posted on the Putnam County Real Property Tax Service Agency website,¹ and current equalization rates come from the New York State Office of Real Property Tax Services.

One date to keep in mind while you evaluate: the assessor fixes your property’s condition and ownership as of March 1, the taxable status date. Damage or improvements after that date won’t show up until the following year. Serious problems that existed before March 1 and weren’t accounted for are strong grounds for a grievance.

The Four Legal Grounds

New York Real Property Tax Law Section 524 limits grievances to four grounds, and you must pick at least one on the form.⁴

Excessive assessment: the valuation exceeds market value. This also covers denial of a partial exemption like STAR or the senior citizen exemption. Most homeowner grievances fit here.
Unequal assessment: your property is assessed at a higher percentage of market value than the average parcel on the same roll.
Unlawful assessment: the property is legally exempt or sits outside the taxing municipality’s borders.
Misclassification: the parcel is in the wrong tax class, for example a home taxed at a commercial rate.

When in doubt, pick excessive assessment. It’s the right fit for almost any homeowner who believes the dollar figure is simply too high.

Start by Talking to the Assessor

The New York State Department of Taxation and Finance recommends an informal conversation with the assessor before filing anything.⁵ The assessor may not know about a deteriorating roof, a failed septic system, or interior problems that affect value. Photos and documentation can prompt a voluntary correction with no paperwork and no hearing.

Even if the assessor won’t budge, the meeting is useful. You’ll see the comparable sales they used, the data in your property record card, and the reasoning behind the number. All of that sharpens a formal grievance. Visit the assessor’s office between May 1, when the tentative roll is published,⁶ and Grievance Day.

Filing Form RP-524

The formal complaint is Form RP-524 (Complaint on Real Property Assessment), available at your town assessor’s office or as a fillable PDF from the New York State Department of Taxation and Finance.⁷ It asks for your tax map number (on your tax bill and the tentative roll), the legal ground you’re asserting, and your own estimate of market value.

Fill out every relevant section. Incomplete forms can be dismissed, and a dismissal also blocks you from going to court afterward.⁸ If someone else is filing on your behalf, include a written authorization dated within the same calendar year. The form carries a certification that your statements are true, so base your value estimate on real evidence.

Set that estimate carefully. If you later go to Small Claims Assessment Review, you cannot ask the hearing officer for a lower value than the one you wrote on the RP-524.

Evidence That Works

The strongest single document is a professional appraisal from a licensed appraiser, typically $400 to $700 for a residential property. It gives the board an independent market value backed by methodology they recognize.

If you’d rather not spend that, build the case yourself from three to five recent comparable sales (within the past year) of homes with similar square footage, lot size, age, and condition. For physical problems, contractor estimates for foundation repair, roof replacement, or mold remediation attach a dollar figure the board can weigh. Photos help. The point is to give the board concrete reasons to doubt the assessor’s number, not just your opinion that it’s wrong.

The Deadlines

The calendar is tight and unforgiving. Miss any of these and you lose the right to challenge this year’s assessment.

March 1, taxable status date: condition and ownership are frozen; also the deadline to apply for most exemptions.
May 1, tentative roll published: the window opens for informal review and preparing your grievance.⁶
Fourth Tuesday in May, Grievance Day: the Board of Assessment Review convenes. Your RP-524 and supporting documents must be filed by this date. Putnam County towns typically hold evening hearings.
July 1, final assessment roll filed: the Board’s decisions take effect, and the clock starts for court appeals.²
30 days after July 1 (or notice of filing, whichever is later): deadline to file either a Small Claims Assessment Review petition or an Article 7 proceeding.⁹

Hand-delivering your packet to the assessor’s office gives you immediate proof of filing. If you mail it, use certified mail with return receipt.

What the Board Hearing Is Like

Each town’s Board of Assessment Review has three to five residents familiar with local property values. The assessor and the assessor’s staff cannot serve on the board.¹⁰ The hearing is less formal than court, but the board can administer oaths, take testimony, and require you to answer questions. Refusing to cooperate costs you the chance at any reduction.¹¹ The assessor can present rebuttal evidence.

You and the assessor can also stipulate to a value during the process. If both sides sign a stipulation on the RP-524 agreeing to a specific figure, that number goes on the final roll and neither side can challenge it in court.⁴ Most successful grievances end this way. The board issues a written determination, and the result shows up on the July 1 final roll.

If the Board Says No: SCAR or Article 7

Two court paths exist, and your property type decides which one.

Small Claims Assessment Review

SCAR is for owner-occupied one-, two-, or three-family homes. The filing fee is $30, no attorney is required, and an impartial hearing officer decides the case.¹² You must have filed a grievance with the Board first; you cannot skip that step. The equalized value of your property generally cannot exceed $450,000, though you can still use SCAR above that threshold if the reduction you’re seeking is 25 percent or less of the assessed value. You cannot ask SCAR for a lower value than the one you put on your RP-524.

Article 7 Tax Certiorari

Commercial owners, landlords with non-owner-occupied rentals, and homeowners whose properties fall outside the SCAR thresholds file a tax certiorari proceeding in Supreme Court under Article 7. This is a full legal proceeding, typically requires an attorney, and costs substantially more. The 30-day filing window from the final roll (or notice of its filing) applies to both SCAR and Article 7.⁹

After You Win

A successful grievance lowers your assessed value on the current year’s final roll, which cuts the taxes calculated from that roll. The reduction applies only to that year. The assessor can raise the value again next year if market conditions support it, and if that happens you’ll need to grieve again.

Keep paying your full tax bill while the grievance or appeal is pending. If you end up overpaying, you’ll get a refund or credit. For homeowners with escrow, the savings flow through the servicer’s annual escrow analysis, which can produce either a refund check or a lower monthly payment going forward.

Check Your Exemptions First

Before putting work into a grievance, make sure you’re getting every exemption you qualify for. A missing exemption inflates your bill just as much as an inflated value, and the fix is often simpler. If you were entitled to an exemption and the assessor didn’t apply it, that counts as an excessive assessment and goes through the same RP-524 process.⁴

Putnam County’s senior citizen exemption can reduce assessed value by up to 50 percent for owners 65 or older with household income of $50,000 or less, with a sliding scale phasing out up to $58,400 under the most recently published thresholds.¹³ Also check Basic STAR and Enhanced STAR for school taxes, veterans’ exemptions tied to service period and disability rating, and exemptions for people with disabilities. Most exemption applications are due to your town assessor by the March 1 taxable status date, so planning ahead matters.
