Sales Tax Duties for Gas Station Owners
As a gas station owner in Chicago, Illinois, you have duties to report your sales tax collected, like any other retail business. Over the last two years, the Attorney General has been coming down hard on unremitted sales tax. Over the last year, they went from imposing civil penalties to criminal tax fraud charges; upon conviction, there can be jail time.
