We will use this information to identify the affected businesses and to correct our records to reflect the change in taxing jurisdiction.
Note: Illinois Business Tax (IBT) numbers eventually will be replaced by Account IDs when that tax is included in the new system. At the end of the four-year transition period, use of the term “IBT” will be discontinued.
Failing to notify us of an annexation may result in the misallocation of sales tax revenue. Currently the law provides for adjustment of only those amounts erroneously disbursed within the six month period prior to the discovery of misallocation. Delays in submitting proper notification of an annexation may result in unrecoverable revenue losses.
For example, if in January 2000, you annexed a portion of land that contained a retail business but you did not notify us that this annexation had occurred until January 2001, we could adjust only the portion of money that had been misallocated between the months of July 2000 and December 2000. Any money that was allocated to the county between January 2000 and June 2000 would not be adjusted.
