How Property Tax Works

Greene County, New York operates on a property tax system that funds essential local services including schools, county operations, town services, and special districts. Property taxes are the primary revenue source for these governmental entities, with the fiscal year running from January 1 through December 31. Tax bills are mailed to property owners in January and are due by January 31 each year.

The effective property tax rate in Greene County varies significantly by location within the county due to different combinations of county, town, school district, and special district taxes. Based on recent data, the county general tax rate has ranged from approximately 18-20 per thousand of assessed value in recent years. However, when combined with school taxes, town taxes, and any applicable special district assessments, total effective rates typically range from 2.5% to 4.0% of assessed value depending on your specific location and the services provided in your area.

Property owners should note that Greene County uses a fractional assessment system, meaning properties are assessed at a percentage of their full market value. This percentage can vary by town and is applied uniformly within each assessing jurisdiction.

Section 4

Supplemental Tax Bills

Supplemental taxes in Greene County are additional tax bills issued when there are changes to property ownership, new construction, or property improvements that occur after the annual assessment roll is finalized. These supplemental bills ensure that property taxes are properly allocated for the portion of the tax year affected by the change.

Common triggers for supplemental taxes include: change of ownership that removes existing exemptions, completion of new construction or major renovations, subdivision of property, or discovery of previously unassessed improvements. The supplemental tax is calculated based on the difference between the old and new assessed values, prorated for the portion of the tax year remaining after the change occurred.

For example, if a homeowner completes a $100,000 addition in July and the assessed value increases by $75,000, they would receive a supplemental tax bill for six months (July through December) based on the additional assessed value multiplied by the applicable tax rate. This supplemental bill would be due within 30 days of issuance and is separate from the regular January tax bill.

Escrow & Property Taxes

Most mortgage lenders in Greene County require borrowers to maintain an escrow account for property tax payments. The lender collects monthly payments equal to 1/12th of the annual property tax bill and holds these funds to pay taxes when due on January 31st. Lenders typically add a cushion of 1-2 months to ensure adequate funds are available.

Your lender will receive a copy of your tax bill and pay it directly to the Greene County tax collector. You should verify that payments are made correctly and on time, as you remain ultimately responsible for ensuring taxes are paid. If your tax bill changes due to reassessment or changes in exemptions, your monthly escrow payment will be adjusted accordingly during the annual escrow analysis.

Property owners without mortgages or those who have paid off their loans are responsible for paying taxes directly to their local tax collector by January 31st each year. Most jurisdictions offer online payment options, and some may offer installment payment plans for qualifying taxpayers.
