Form IL-990-T-V, officially titled “Payment Voucher for Exempt Organization Income and Replacement Tax,” is a form issued by the Illinois Department of Revenue (IDOR). It’s used by tax-exempt organizations to submit payments for the Illinois Exempt Organization Income and Replacement Tax — typically when filing Form IL-990-T (the income tax return for exempt organizations).
This voucher serves one primary purpose: to properly credit payments made by check or money order to the correct taxpayer and tax period. It’s used when a payment is due and you’re not paying electronically. The state encourages online payments through tax.illinois.gov to save time and confirm transactions immediately, but if you choose to mail a payment, Form IL-990-T-V must accompany your check or money order.
The voucher applies to all types of IL-990-T payments — whether it’s an extension payment, prepayment, or payment submitted with a return. However, if no payment is due or you’ve already paid electronically, you should not file this form.
How To File Form IL-990-T-V
Filing Options
You have two options for paying the tax amount due:
- Electronic Payment:
Visit tax.illinois.gov or scan the QR code on the form to pay directly online.- Advantages include avoiding mailing delays, skipping postage costs, and getting instant confirmation.
- You must pay electronically if IDOR has notified you that you’re required to do so.
- Mail Payment:
If you choose to pay by mail, complete the voucher carefully, attach your payment, and mail both to:
Illinois Department of Revenue, P.O. Box 19053, Springfield, IL 62794-9053. If you’re mailing your tax return at the same time, attach the voucher and payment to the front page of your return, then send them together to the filing address shown on the return.

How To Complete Form IL-990-T-V
Form IL-990-T-V is a short but critical form. Here’s how to complete each section clearly:
Header: “If No Payment Is Due…”
At the top of the form, you’re reminded not to file the voucher if you:
- owe nothing, or
- are paying electronically.
This prevents unnecessary paperwork and processing delays.
Section 1: Taxpayer Identification
- FEIN (Federal Employer Identification Number):
Enter your organization’s nine-digit FEIN. This uniquely identifies your account with both the IRS and IDOR.
Example:36-1234567. - Name:
Enter the full legal name of the exempt organization, exactly as it appears on your Form IL-990-T. - C/O (Care Of):
If correspondence should go to a representative (like an accountant, tax preparer, or administrator), list their name here. Otherwise, leave blank. - Mailing Address:
Write the organization’s current mailing address, including any suite or box numbers. - City, State, ZIP:
Enter your city, state abbreviation, and ZIP code (use ZIP + 4 if available). - Phone:
Provide a daytime contact number, including the area code, so IDOR can reach you if needed.
Section 2: Tax Year Ending
- Enter the month and year in which your tax year ends.
Example: If your fiscal year ends June 30, 2024, write:
Month: 06 Year: 2024.
This ensures that the payment applies to the correct filing period.
Section 3: Payment Amount
- On the line marked with a dollar sign ($), enter the exact payment amount in whole dollars only (no cents).
Example:1500(for $1,500.00). - Double-check that the amount matches what’s due on your Form IL-990-T or payment notice.
Section 4: Instructions for Mailing Payment
Follow these exact steps if paying by check or money order:
- Write your FEIN, tax year ending, and “IL-990-T-V” on the check or money order.
- Make it payable to “Illinois Department of Revenue.”
- Detach the voucher portion of the form.
- Enclose your check or money order with the voucher and mail it to the address printed on the form:
