A filled-in Form ITR-1 example: a bakery asks for clearance for a license renewal

Form ITR-1 example filled out, example: a bakery asks for clearance for a license renewal
Dana Sample, owner of Sample Bakery LLC, fills out Form ITR-1. It has employees and an office in Illinois, makes no retail sales, and needs a license renewal clearance. The picture shows the filled form, and its names and figures are sample values. The business does business as Sample Bakery, started in Illinois on 03/01/2015 and is identified by its FEIN, so the Social Security number stays empty. Dana checks only Withholding Income Tax in Step 2 because the business has employees, so the other Step 2 boxes and the Excise Tax License number stay empty. In Step 3 only License renewal required by another agency is checked, so the other Step 3 boxes and both explain lines stay empty. The clearance is not sent to a third party, so the third party lines stay empty. Dana signs as owner on 09/15/2026, and because the fillable form has no field for the signature line, Dana signs a printed copy by hand.
