Continuously. Changes are received by the Mapping Department daily. These changes usually result from deeds being assessed in the Appraisal Department and/or recorded in the Probate Office. Other updates come from newly recorded subdivision plats, right-of-way surveys, etc.

A tax map is used to identify ownership of each parcel of land in the county. These drawings are representations of geographical features, property lines, and parcel identification numbers. Although tax maps are for tax purposes only and cannot be used for conveyance, these maps have proven to be very helpful to taxpayers for many reasons.

This 16 digit number uniquely identifies every piece of property within the county for tax purposes. The parcel ID number is broken down as follows: Example: 16-09-31-3-004-019.003 16: Locator – this number is derived from the township and range of the property. The legend located on every tax map will depict this grid of locator numbers. 09: Area – this number refers the ‘4 section area’ the property is located inside of. See the legend on the map for details. 31: Section – this is the section number 3: Quarter-Section – this identifies the quarter section (i.e. NE1/4=1, NW1/4=2, SW1/4=3, SE1/4=4) 004: Block – some maps are broken down into blocks because of the number of parcels per map, this number identifies which block on the map 019.003: Parcel and sub-parcel – this is the number found on the map. Most often, leading zeros will not appear on the map. (i.e. 19.03)

Multiple parcel numbers do not affect the tax rate on your property. These numbers are simply for location and identification. There are several possible reasons for multiple parcel identification numbers: Property lies in two different sections, and each section is numbered independently, each parcel was previously owned by different individuals, or property was purchased at different times.
