How it works
In Onondaga County, each town and the City of Syracuse determines the assessed value of property and places it on the local assessment roll. The county itself does not perform assessments. Property tax is generally calculated by multiplying the taxable assessed value by the applicable tax rates per $1,000 of assessed value. A typical parcel may be subject to several separate tax components, including county tax, town or city tax, school district tax, and in some cases village or special district taxes. These rates are set by the relevant local governments and school districts. The calculator combines user-provided rates and applies them to the assessed value to estimate total annual property tax.
Examples
Properties located in different towns or school districts may face different combined rates. The calculator reflects this by applying the total rate provided to the assessed value entered.
Limitations and important notes
This calculator provides an estimated property tax only. Actual tax bills depend on the parcel’s official taxable assessed value as shown on the assessment roll, applicable exemptions under New York law, and the specific rates adopted by the county, municipality, school district, and any special districts. Equalization rates are used by the county for apportionment purposes, but individual tax bills are based on the taxable assessed value and the rates applicable to the parcel’s jurisdiction. Special assessments or district charges may apply and are not automatically included unless added to the combined local property tax rate. Always verify final amounts with official county or local tax authorities.
FAQs
Is property tax in Onondaga County based on assessed value or market value?
Property taxes are based on the assessed value determined by the local assessing unit. Equalization rates measure the relationship between assessed value and full market value for apportionment purposes, but individual tax calculations use the taxable assessed value.
What tax rates apply to a property in Onondaga County?
A property may be subject to county, town or city, school district, and possibly village or special district tax rates. The total annual property tax is based on the combined local property tax rate applicable to the parcel.
Do exemptions affect property tax in Onondaga County?
Yes. Applicable exemptions reduce the taxable assessed value before tax rates are applied. The type and amount of exemption depend on eligibility under New York Real Property Tax Law and local adoption.
Why can two similar properties have different tax bills?
Differences in location, school district, village status, special districts, assessed value, and exemptions can all affect the combined local property tax rate and the resulting tax bill.
