Equalization Rates & Residential Assessment Ratios
Calculating Full Market Value & Assessed Value
- The City assesses all real property at a percentage of market value.
- The percentage is known as an Equalization Rate (ER) for commercial property and multifamily residences (4 plus families and apartment buildings).
- The percentage for residential properties (owner-occupied one to three-family dwellings) is known as the Residential Assessment Ratio (RAR).
- These rates are established annually by the NYS Department of Taxation and Finance (see their link to Munipro below).
The ER and RAR are used to determine a property's full market value. It should be noted that this is merely a calculation. It is not what a property would sell for and should not be used to determine a listing price. It is used to determine if a property is fairly assessed.
The formulas are:
Property Class: Assessed Value Divided by Rate/Ratio Equals Market Value
- Residential: 8,600 ÷ 3.97% level of assessment = $216,625 full market value.
- Commercial: 75,000 ÷ 3.85% (2012 ER) = $1,948,052
- Inversely, this formula is used to determine the assessment:
Property Class: Market Value Times Rate/Ratio Equals Assessed Value
- Residential: $229,381 × 3.88% (2013 RAR) = 8,900
- Commercial: $ 1,948,052 × 3.85% (2012 ER) = 125,000
NYS Department of Taxation and Finance performs a statistical analysis each year to adjust the rate and ratio in accordance with real estate market trends. An increasing rate/ratio results in a lower market value calculation; inversely, a lower rate/ratio results in a higher market value. This example illustrates this relationship for a single-family home with an assessment of 8,900:
Year: Assessment Divided by RAR = Market Value (Effect)
- 2005: 8,900 ÷ 3.05% = $291,803
- 2006: 8,900 ÷ 2.55% (decreasing) = $349,020 (increasing)
- 2007: 8,900 ÷ 2.45% (decreasing) = $363,265 (increasing)
- 2008: 8,900 ÷ 2.63% (increasing) = $338,403 (declining)
- 2009: 8,900 ÷ 2.64% (slight increase) = $337,121 (slight decrease)
- 2010: 8,900 ÷ 3.20% (increasing) = $278,125 (declining)
- 2011: 8,900 ÷ 3.36% (increasing) = $264,881 (declining)
- 2012: 8,900 ÷ 3.48% (increasing) = $255,747 (declining)
- 2013: 8,900 ÷ 3.88% (increasing) = $229,381 (declining)
In order to determine taxes, you would need to obtain the current tax rate from the City's Finance Department and multiply it by the assessment less any exemptions. Tax rates are usually expressed in rates per thousand. An example of the calculation of a school tax would be:
Assessment Less Exemption(s) Divided by 1000 Times Tax Rate = Taxes
Example (See Note): 8,900- 2,970 (STAR) ÷1000 × 603.943369 (school rate) = $3,581.38
