If the worker controls how the work is done, the worker is not your employee. This person usually provides his or her own tools and offers services to the general public in an independent business.

If you employ household employees and you are eligible to file federal Schedule H (Form 1040), Household Employment Taxes, you may file your Illinois withholding tax annually on Form IL-1040, Illinois Individual Income Tax, Line 22. We encourage you to file electronically using MyTax Illinois. For more detailed information, see Pub-121, Illinois Income Tax Withholding for Household Employees. No registration is required to use this option.
If you do not file annually on Form IL-1040, Line 22, you must file Form IL-941, Illinois Withholding Income Tax Return, to report and pay the income tax you withheld. See Pub-131, Withholding Income Tax Filing and Payment Requirements, to determine how often you are required to report and pay withholding tax. You must register with us (the Illinois Department of Revenue) online or by completing Form REG-1, Illinois Business Registration. For new registrants, Form IL-941 is required quarterly and payments are required monthly.
Note: If you already file IL-941 and you would like to convert to the annual IL-1040, Line 22 option, you must call us first at 217 785‐3707 to close your IL‐941 account. If you do not, you may be subject to penalties and collection action.
