Illinois Revenue Dept Address 2026: P.O. Box & Office Mail
A practical Illinois Department of Revenue address guide for taxpayers, businesses, payroll teams, tax professionals and Illinois residents who need the correct IDOR P.O. Box, office location, tax return mailing address, payment voucher address, amended return address, business registration mail address, sales tax address, withholding tax address or regional office contact.
Quick Answer: What Is the Illinois Department of Revenue Address?
There is not one single Illinois Department of Revenue address for every tax issue. IDOR uses different P.O. Boxes and office addresses based on the form, tax type, payment status, notice type and department unit. For example, an IL-1040 individual return without payment goes to a different P.O. Box than an IL-1040 with payment, an amended return, estimated tax payment, business registration request, sales tax correspondence or withholding tax return.
For individual returns
Use the IL-1040 address based on whether payment is enclosed. Do not use a general correspondence P.O. Box for a paper return unless the official instruction tells you to.
For payments
Use MyTax Illinois or the payment voucher address shown on the voucher. If you do not have a notice, bill or voucher, IDOR lists a separate general payment P.O. Box.
For office visits
IDOR has regional offices including Chicago, Des Plaines, Fairview Heights, Marion, Rockford and Springfield. Office visits are different from tax-return mailing addresses.

Illinois Department of Revenue Payment Address: Voucher, Check, Money Order and MyTax Illinois
IDOR encourages electronic payment methods because they are faster and reduce mailing mistakes. If you must mail a paper check or money order, use the correct voucher or notice address. If there is no notice, bill or voucher, IDOR lists a general payment mailing address.
General payment without notice, bill or voucher
Use this only when you do not have a notice, bill or voucher and you are mailing an individual income tax balance-due payment.
ILLINOIS DEPARTMENT OF REVENUE PO BOX 19006 SPRINGFIELD IL 62794-9006
- Make the check payable to Illinois Department of Revenue.
- Write SSN and spouse SSN if filing jointly.

Before You Mail Anything to Illinois DOR: Address, Envelope and Tracking Checklist
A correct P.O. Box is only one part of successful mailing. The wrong form, missing signature, no voucher, wrong tax year, wrong Social Security number, or missing documentation can cause delays even if the envelope goes to the right place.
Mailing checklist
- Use the current tax-year form and instructions.
- Check whether the form is with payment or without payment.
- Use the exact P.O. Box printed on the official instruction or notice.
- Sign and date the return or letter when required.
- Include schedules, W-2/1099 copies and attachments when required.
- Write tax year, tax type and ID/account number on checks and letters.
- Keep a full copy of everything mailed.
Envelope and proof tips
- Use USPS formatting exactly: department name, P.O. Box, city, state and ZIP+4.
- Do not mix multiple tax types in one vague envelope unless IDOR instructions allow it.
- Use certified mail or tracking when deadline proof matters.
- Do not mail cash.
- Do not use a street office address for a P.O. Box return unless instructions say so.
- For complex notices, call or use MyTax Illinois before mailing.
Illinois DOR Notice, Bill, Adjustment Letter or Return Correction: Which Address Should You Use?

| Balance due bill | Voucher, payment address, tax type and account number. | Pay electronically or use address printed on the voucher/bill. |
