Uniform Percentage of Value
The percentage of market value (full value) used by an assessing unit to establish uniform assessments. This value must appear on the tentative roll. Real Property Tax Law Section 305 specifies, "all real property in each assessing unit shall be assessed at a uniform percentage of value..."

Taxable Status Date - March 1st
The Assessor is required by New York State law to value property as it is on this date. A partially completed building will receive a partial assessment based on its estimated percentage of completion as of March 1st. If you suffer a loss to your property (ex: fire, demolition) after this date you will see no reduction for that loss on forthcoming roll. Exemption forms must be filed by this date also.

Residential Assessment Ratio (RAR)
A percentage established by the State Board of Real Property Services according to law, using the ratio of assessed value to the sales price for each usable residential sale in a recent one-year period. Ratios are then listed from highest to lowest; the midpoint (median) ratio is selected as the RAR. The RAR can be used to prove that a residential property is assessed at a higher level than other homes on the assessment roll. Your locality's RAR indicates at what percent of full value residential properties are assessed. For example, a RAR of 20 indicates that residential properties are assessed at approximately 20 percent of their full value.

Equalization Rate
"State equalization rate" means the percentage of full value at which taxable real property in a county, city, town or village is assessed as determined by the state board." (RPTL Section 102) The rate is a ratio of the sum of the locally determined assessed values for all taxable parcels for a given assessment roll divided by ORPS's estimate of total full value for that same roll.

Cold War Veterans Exemption - NEW
