What is a GIS?
One of the primary elements of the SUTS System allows businesses to easily, and with the aid of free technology, identify the correct taxing jurisdictions related to the sale of a taxable good or service. The Geographic Information System (GIS) now allows businesses to look up the specific sales tax rate for an individual address. The GIS not only shows state sales tax information, but it also includes sales tax information for counties, municipalities, and special taxation districts. This system allows for a complete tax rate to be determined so the correct tax is collected from customers in real-time.
Also, if your internal point of sale system supports it, the GIS information can be accessed through an Application Programming Interface (API).This API can automatically reference current tax information directly from the CDOR. Please note that the Department will need to verify that you have registered for an account for the Remittance Portal before using the API. Additionally, in some instances, the base map from Google cannot resolve some queries where, for example, “county road” is abbreviated as C.R. This issue is being investigated by Google Maps staff and should be resolved shortly.
What is an API?
The new GIS includes an API, which is short for "application programming interface," which is a software intermediary that allows two systems to talk to one another. An API assists you in automating your point of sale (POS) system. The API automatically retrieves sales tax rate calculation information from the GIS database. It can also help integrate GIS database information into your online ordering and point of sale systems.
