Illinois Withholding Requirements

The state of Illinois requires all employers to withhold state income taxes from their employees' paychecks. In addition to that, they must also contribute to state unemployment taxes each quarter. To know how much tax to withhold from employees each pay period, you must collect Form IL W-4, Employee's Withholding Allowance Certificate.

According to the Illinois Department of Revenue, all taxes are equal, so a flat rate of 4.95% is imposed as a tax rate for all employees, and 7% for corporations. Certain exemptions in withholdings are allowed if the employee is over 65 years of age or blind

The state has no local taxes and state disability insurance. But does support reciprocal agreements with certain states.

As you are required to report both state taxes and unemployment wages, you must register to the following agencies:

  • The Department of Revenue- For reporting state taxes withheld from employee wages. To file these taxes, Form IL-941 and IL-501 are needed. You can file electronically through the department’s online site MyTax Illinois.
  • The Department of Labor- For reporting unemployment taxes using MyTax Illinois. To file these taxes, Form UI-3/40 is needed.

Once you complete your registration, you will be provided with an Illinois state withholding tax ID, unemployment ID, and tax rate. We suggest you record this information in PayWow to remit and file taxes on your behalf.

Though the state mandates on minimum wage payments, there are some exemptions:

  • Employees till their 90 days of employment can be paid 50 cents less than the usual wage rate.

Reciprocal States

Reciprocal agreements between states are agreements that allow employees living in one state and working in another state to pay taxes only to their state of residence.

Withholding Tax Forms

IL-941: Illinois Withholding Income Tax Return

You are required to file Form IL-941 if you have paid wages and other employee compensations like bonuses, commissions, and overtime pay on a W-2.

Or, you paid non-wage income like pensions, annuities, unemployment income, and sick pay. The state mandates the filing of form 941, even if there was no tax withheld during the reporting period.

Usually, the form is due quarterly, and unlike the federal government, Illinois does not require an annual reconciliation return.

You must make withholding tax payments electronically if you are assigned to the semi-weekly pay schedule. If you are unable to file 941 form electronically, you must complete form IL-900-EW to request a waiver.

As form 941 falls due each quarter, the deadline to file Form IL-941 is on the last day of the month that follows the end of the quarter.
