Tax bills & filing dates

These are the dates and qualifications recorded in the directory. Confirm your tax year and current deadline with the official office and your property’s notice.

Payment deadline: 2026 property-tax payment dates are set by the applicable town, school district, or special district; the County Comptroller handles delinquent tax-lien information and payments under the county tax-lien schedule.
Assessment appeal: May 19, 2026 is the standard Suffolk County town grievance day (third Tuesday in May); confirm the applicable town assessor's filing deadline and hearing time. Small Claims Assessment Review deadlines are set by the town assessor.

Exemptions & appeals

View exemption application

Exemption filing

March 1, 2026 for most New York local property-tax exemptions, including STAR exemption and senior exemptions; file with the applicable municipal assessor. New STAR credit applicants register with New York State instead.

Senior relief

Enhanced STAR for 2026-2027: one resident owner must be at least 65 by December 31, 2026 and qualifying income is $110,750 or less; it applies to school taxes. A municipality may also grant the senior-citizens exemption under RPTL §467, with local income limits and filing rules.

Valuation limits

New York's property-tax cap limits annual local-government and school-district tax-levy growth generally to the lower of 2% or inflation, subject to statutory exclusions and overrides; it is a levy cap, not an individual parcel assessed-value cap. Assessors must maintain uniform municipal assessment levels.

For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
