This publication is written in the plain English style so the tax information is easier to understand. As a result, we do not directly quote
Illinois statutes and the Illinois Administrative Code. The contents of this publication are informational only and do not take the place
of statutes, rules, and court decisions. For many topics covered in this publication, we have provided a reference to the applicable
section or part of the Illinois Administrative Code for further clarification or more detail. All of the sections and parts referenced can
be found in Title 86 of the Code.

2025 Withholding Income Tax Payment and
Return Due Dates

General Information

			do I make my withholding payments?
How
•	

Payments are made electronically or with Form IL-501 on either a monthly or semi-weekly payment schedule.

•	

Electronic mandates for Illinois Withholding Income Tax: You must make withholding tax payments electronically if you are
assigned to the semi-weekly payment schedule.

How often must I make withholding payments?
There are two different payment schedules — monthly and semi-weekly.
•	

Monthly payers: Payments are due on the 15th day of the month following the month in which the tax was withheld.

•	

Semi-weekly payers: Illinois follows the federal rule that allows you at least three banking days to make your payments.
Semi-weekly IL-501 payments are due by Wednesday for amounts withheld on the preceding Wednesday, Thursday, or Friday,
and by Friday for amounts withheld on the preceding Saturday, Sunday, Monday, or Tuesday.
Anytime a due date falls on a weekend or state recognized holiday, we adjust the due date to the next business day.

How do I file Form IL-941, Illinois Withholding Income Tax Return?
All Forms IL-941 must be filed electronically. If you are unable to file electronically, you may request Form IL-900-EW, Waiver
Request, through our Taxpayer Assistance Division. The waiver request must be completed and submitted back to IDOR. You will be
notified if the waiver request is approved or denied.
	Avoid common errors: Make sure that your Form IL-941 includes your withholding information in Step 4. IDOR does not 		
			 calculate these entries for you.
