If you own property in the City of Watertown and want a property tax exemption on next year's bills, your application has to reach the City Assessor's Office before December 1. That is earlier than almost everywhere else in Jefferson County. Here is who qualifies, which form to use, and what to do this month.
Sources: the City Assessor's exemptions page, the Assessor's presentation at the Oct. 13 City Council work session (minutes, video), and New York State's Office of Real Property Tax Services (ORPTS) pages on tax.ny.gov.
Why December 1 matters in the city
The city's exemptions page says: "All applications for exemptions must be submitted prior to December 1st to apply for the following years Taxes." (city)
December 1 is the city's taxable status date, the day the assessment roll is fixed for the coming year. At the Oct. 13 work session, City Assessor Kimberli Johnston told the Council: "Our taxable status date is December 1st." She added that everyone else in the county uses March 1. (video, at about 1:07:50)
The March 1 deadline on most state pages and forms does not apply to city property. December 1, 2026 is a Tuesday. Because the city's wording is "prior to," the safe plan is to have your paperwork in by Monday, Nov. 30.
City, county and school taxes. One application to the city covers your property, but each taxing body sets its own rules for some exemptions. A 2024 Assessor's memo said a city-adopted exemption "would apply only to the City of Watertown taxes" unless the county or school also adopts it before December. (May 13, 2024 work session agenda) The senior exemption below is a good example: the city, the county and the school district each use a different income limit. We could not find a separate county or school filing deadline for city properties; ask the Assessor's Office if you are unsure.

STAR: register with the state
The city lists STAR first and points owners to the state. (city) The old STAR exemption (a reduction on your school tax bill) is closed to new applicants. If you have had it since 2015 you can keep it on the same home. Everyone else gets the STAR credit, paid by the state. (NYS eligibility)
- Basic STAR credit: any age, household income of $500,000 or less.
- Enhanced STAR: at least one resident owner 65 or older by Dec. 31 of the benefit year; income of $110,750 or less for 2026 benefits and $113,550 or less for 2027. (NYS)
- How to register: through the state's Homeowner Benefit Portal in an Online Services account, or by phone at (518) 457-2036. You register once; the state reviews eligibility each year. (NYS)
STAR registration is not tied to December 1, but new buyers should do it now.
Senior citizens (RPTL 467)
The city's page lists the senior exemption for owners over 65 with annual income under $23,100. (city) At the Oct. 13 work session, the Assessor explained the city's sliding scale: a 50% exemption at $17,400 or less, shrinking as income rises, and nothing at $23,100 or more. She said the county's ceiling is also $23,100 and the school district's is $18,500. (minutes; video, at about 1:20:30)
State rules: generally every owner must be 65+ (spouses and siblings have exceptions), you must have owned the home 12 consecutive months, and it must be your legal residence. Income starts with federal adjusted gross income, with Social Security added back. First-time applicants file RP-467; renewals use RP-467-Rnw; if you did not file a tax return, add the RP-467 worksheet. (NYS)
A 2024 city memo noted that qualifying for this exemption also gets you favorable water and sewer rates (no minimum charge). (May 2024 memo)
Under discussion, not decided: On Oct. 13 the Council heard two ways to widen the senior exemption: stop counting Social Security as income, or raise the ceiling to $31,500. Council members asked for more numbers on how many residents would qualify and the effect on revenue. No vote had been taken as of the Nov. 2 meeting. (minutes) Apply under today's limits.
Veterans
The city offers the alternative veterans exemption (RP-458-a). (city) Under state law it reduces the assessment of a veteran's primary residence by 15% for wartime service, another 10% for combat-zone service, and another amount equal to half the service-connected disability rating, each subject to dollar caps the local government sets. You apply once, and re-file if you move or your disability rating changes. (NYS) We could not find the city's current dollar caps online.
Permanently and totally disabled veterans: State law now lets each city, county and school district choose whether to fully exempt the home of a veteran the VA rates permanently and totally disabled from service. The Assessor presented the option on Oct. 13 and said 142 city properties have veterans with a 100% rating. Council Member Kimball estimated a revenue loss of $75,000 to $85,000; Council Member Shoen questioned whether the designation should qualify when it does not limit earned income; Kimball and Council Member Garrabrant asked for fiscal estimates before deciding. (minutes) The city has not adopted it as of Nov. 2. The Assessor said the state may give extra time to apply if it is adopted. (video, at about 1:08:05) The application would be the same RP-458-a form. (NYS)
The Cold War veterans exemption (RP-458-b, service from Sept. 2, 1945 to Dec. 26, 1991) is a separate local option that cannot be combined with the alternative exemption for the same tax. (NYS) The city's page does not list it; ask the Assessor.
Persons with disabilities and farmland
The state's exemption for persons with disabilities and limited incomes (RPTL 459-c, form RP-459-c) can cut a home's assessment by up to 50%, but only where the local government has adopted it. (NYS) It is not on the city's exemptions page, and we could not confirm whether the city offers it. The same goes for agricultural assessments (form RP-305). Call (315) 785-7760 before Dec. 1 if either may apply to you.
For businesses and landlords
- Commercial construction (485-b): commercial, business or industrial work costing more than $10,000 (not ordinary repairs). The standard schedule exempts 50% of the added value in year one, dropping 5% a year for nine years. File within one year of finishing the work and by the taxable status date. (RP-485-b instructions)
- Home improvements (421-f): over $3,000 on a one- or two-family house at least five years old; up to $80,000 of added value, phased out over eight years. (RP-421-f instructions)
What to do this month
- Pick your exemption from the table and download the form.
- Gather proof: age, income (for the senior exemption, your 2025 federal return), VA letters, permits or contractor invoices.
- Deliver it to Room 201, City Hall, by Monday, Nov. 30. Email the office first if you are unsure what they need.
- New homeowner? Also register for the STAR credit with the state.
