2026 fiscal calendar
Know the tax date before it becomes a penalty date.
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The verified record below separates published figures from dates that require confirmation with Broome County Real Property Tax Service.
Effective rate
county, town, city, village, school, and special-district rates vary; no single countywide 2026 effective rate is published.
Statement mailing
bills are issued by the applicable town, city, school district, or county collection office; no single countywide 2026 mailing date is published.
Payment deadline
2026 collection schedule varies by taxing authority; Broome County's centralized collection page states school-tax collection is generally September-October and town/county collection January-March, with delinquent taxes collected year-round at the county office.
Valuation protest
May 26, 2026 (fourth Tuesday in May); Broome County states grievance day is the fourth Tuesday in May annually, and assessment disputes are handled by the local assessor.
Critical payment warning
Do not assume a grace period.
The verified county record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat the published payment deadline as a hard operational date and retain your receipt or confirmation number.
Read the calendar in order
From assessment to collection
1. Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
2. Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
3. Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
