Calling all county and municipal GIS folks! Or anyone else who’s interested in learning how e-retailers know just how much sales tax to charge you.
Abstract
Revenue (IDOR) has an annual process during which they contact local governments asking that they review the boundaries reported to IDOR for accuracy. This communication is initiated to the clerks and/or treasurers, who are responsible for tax matters. We’d like to take the time to reach out directly to the GIS analysts as you are the ones often tasked with carrying out the boundary review itself.
