The 1040 instructions show to mail payment to:
PO Box 19027
Springfield, IL 62794-9027
The payment voucher form (1040-V) shows to mail payment to:
Illinois Dept of Revenue
Springfield, IL 62726-0001..
Where should I mail the payment?
Thanks for your reply. However, the question was regarding state tax return payments only, not federal taxes. I finally received an answer from the State:
If payment is being submitted with a return, it should be mailed to the PO BOX 19027.
If payment is being submitted without a return (and must include the payment voucher, e.g., estimated tax payments for 1099 employees, etc...), then payment should be sent to the 62726-0001 zip code address.
Per Illinois Department of Revenue website:
With Payment:
PO BOX 19027
SPRINGFIELD IL 62794-9027
Per IRS website:
Internal Revenue Service
P.O. Box 931000
Louisville, KY 40293-1000
