Annual Sales Tax Jurisdiction Boundary Verification Map

On February 1, 2024, LTAD will make its local taxing jurisdiction boundaries available, which requires annual review for accuracy by local governments. Local governments have the option of providing their boundary file which IDOR will overlay onto its maps to make any necessary corrections. Alternatively, IDOR can provide shape files to local governments which can then be used to determine if any boundary changes are needed.

Local governments may report corrections or request/provide a boundary file using the contact information below. Please note: Changes must be reported by April 1, 2024.  All changes will take effect July 1, 2024. Any updates not reported by April 1, other than boundary changes made by local ordinances, such as annexations or disconnections, will not be made until July 1, 2025.
