Calculating market values and property taxes doesn’t happen overnight. The process of collecting open market sales data to determining market values to calculating taxes to actually collecting property taxes takes more than three years from start to finish.

How the process works for 2015 property taxes
- Oct. 1, 2012–Sept. 30, 2013: Data from open market sales of property is collected to form basis of the 2014 assessment.
- Oct. 11, 2013–February 2014: The Assessing Office uses the data to establish the 2014 market value.
- Jan. 2, 2014: The "as of" date the 2014 market value for taxes payable in 2015 is effective.
- March 2014: Assessing Office sends every property owner a Notice of Valuation, explaining the market value of the property as of Jan. 2 for taxes paid in 2015.
- March–May 2014: Residents can appeal the market value.
- November 2014: Proposed Tax Statements for 2015 are sent out.
- March 2015: 2015 Property Tax Statements sent.
- May 2015: First half of property taxes due.
- October 2015: Second half of property taxes due.
