Certified Tax Roll Data

After certifying the tax roll each year, our office publishes a Summary of Assessment and Tax Roll showing where your tax dollars go including a ten-year history of property values and taxes.  Each tax code area is listed with the districts included in that area and the tax rate per thousand dollars of assessed value collected for each district.   Other publications include Detail of Taxing District Levies (SAL tables), and several other documents of interest.  In addition, the detailed certified assessment roll data is extracted from the database into several text files that can be downloaded and imported into a database or spreadsheet.
