Retailers doing business in Illinois may be collecting a different sales tax rate on July 1 as changes in various taxing jurisdictions become effective.

According to the Illinois Department of Revenue’s Informational Bulletin, changes to some locally imposed sales taxes will impact the overall rate of sales taxes.

Cook County’s sales tax rate will roll back 0.5 percent on July 1, dropping from 1.75 percent to 1.25 percent and decreasing the City of Chicago rate from 10.25 to 9.75 percent.

In Union County, the rate will rise 0.75 percent; in Stark County, it will increase by 0.5 percent; and in Lawrence County, the rate moves up a full 1 percent.

Retailers will need to adjust cash registers and computer programs that generate sales tax amounts.
