How Property Tax Works

Broome County, New York operates a property tax system that funds essential local services including schools, county government operations, and municipal services. Property taxes are collected by BC Real Property Tax Service and support various taxing jurisdictions including the county, school districts, towns, and cities within Broome County. The county has demonstrated fiscal responsibility by reducing property tax rates by 24% since 2018, with an additional 0.3% reduction implemented for 2025, even as inflation has increased over 25% during the same period.

Property tax rates in Broome County vary significantly by location within the county due to different combinations of special taxing districts, school districts, and municipal boundaries. Homeowners may be subject to county taxes, school district taxes, town or city taxes, and various special district assessments depending on their property's location. The effective tax rate typically ranges around New York's statewide average of approximately 1.4%, though individual properties may experience higher or lower rates based on their specific taxing jurisdictions and available tax credits.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Broome County are additional assessments that may be levied when there are changes to a property's assessed value during the tax year. These typically occur due to new construction, major improvements, or changes in property ownership that trigger reassessment. When improvements are completed or ownership transfers occur after the March 1 "Taxable Status Date," a supplemental assessment may be issued to account for the increased property value.

Supplemental taxes are calculated by applying the current tax rate to the difference between the new assessed value and the original assessed value, prorated for the remaining portion of the tax year. For example, if a property's assessed value increases by $50,000 due to completed renovations in July, and the effective tax rate is 2.5%, the supplemental tax would be approximately $1,250 multiplied by the fraction of the tax year remaining (typically 8/12 months), resulting in a supplemental bill of about $833.

Escrow & Property Taxes

Most mortgage lenders in Broome County require borrowers to maintain an escrow account for property tax payments, particularly when the loan-to-value ratio exceeds 80%. Lenders collect monthly escrow payments as part of your mortgage payment and are responsible for making property tax payments to BC Real Property Tax Service on your behalf. The payment period runs from January through March, with March 1 serving as the final deadline for payment.

Property owners with escrow accounts should verify that their lender has current tax information and is making timely payments. You can monitor your account by contacting BC Real Property Tax Service or checking online payment records. If you pay taxes independently without escrow, mail payments to BC Real Property Tax Service, PO Box 2087, Binghamton, NY 13902. It's important to ensure sufficient funds are maintained in escrow accounts as tax bills can fluctuate annually based on assessment changes and rate adjustments across various taxing districts.

Q: What tax credits are available and do I need to apply? A: The STAR program provides school tax relief credits but requires application.
