Illinois Form IL-1000-E is a one-page certificate that a nonresident business-entity owner signs and hands to the partnership, S corporation, or trust paying it Illinois-source income, so the entity stops withholding Illinois tax on that owner’s distributive share. The owner then files its own Illinois return and pays the tax directly. The certificate goes to the pass-through entity, not to the Illinois Department of Revenue, and once signed it stays in effect indefinitely.1Illinois Department of Revenue. Form IL-1000-E – Certificate of Exemption for Pass-through Withholding Individuals cannot use it. The exemption is available only to corporate, partnership, trust, and estate owners.
Who Can File It
Illinois requires partnerships, S corporations, and trusts to withhold state income tax on distributive shares paid to nonresident members.2Illinois Department of Revenue. Pass-through Entity Information The statute carves out an exemption for nonresident owners “other than an individual” who certify that they will file and pay on their own.3Illinois General Assembly. Illinois Code 35 ILCS 5/709.5 – Withholding by Partnerships, Subchapter S Corporations, and Trusts Eligible owners are:
- Corporations, including Subchapter S corporations
- Partnerships
- Trusts and estates
Nonresident individuals cannot file Form IL-1000-E. The entity must keep withholding on their shares.1Illinois Department of Revenue. Form IL-1000-E – Certificate of Exemption for Pass-through Withholding Owners that are already tax-exempt under Section 501(a) of the Internal Revenue Code or Section 205 of the Illinois Income Tax Act are exempt from the withholding requirement by statute and have no reason to file the certificate at all.3Illinois General Assembly. Illinois Code 35 ILCS 5/709.5 – Withholding by Partnerships, Subchapter S Corporations, and Trusts
How to Fill Out the Certificate
Download the current version from the Illinois Department of Revenue website. The form runs three short steps, and each field has to be complete. A blank or wrong entry gives the pass-through entity no legal cover to stop withholding.
Step 1: Identify the Pass-Through Entity
Enter the name, mailing address, phone number, and Federal Employer Identification Number of the partnership, S corporation, or trust that currently withholds on your share.1Illinois Department of Revenue. Form IL-1000-E – Certificate of Exemption for Pass-through Withholding
Step 2: Identify the Owner
Enter the name, mailing address, phone number, and FEIN of the owner claiming the exemption. The form asks for a FEIN only; there is no field for a Social Security Number, consistent with the ban on individual filers. Then check the box for your business type: corporation, Subchapter S corporation, partnership, trust, or estate.1Illinois Department of Revenue. Form IL-1000-E – Certificate of Exemption for Pass-through Withholding Checking the wrong box or leaving it blank can invalidate the certificate.
Step 3: Sign the Certificate
An owner, officer, fiduciary, or authorized representative signs and dates the form and prints their name and title. The signature commits the owner to two things: filing all required Illinois returns and paying all Illinois tax on income from the entity, and submitting to Illinois personal jurisdiction for collection of any unpaid tax, interest, or penalties on that income.3Illinois General Assembly. Illinois Code 35 ILCS 5/709.5 – Withholding by Partnerships, Subchapter S Corporations, and Trusts
Where to Send It
Give the signed certificate directly to the pass-through entity. Do not mail it to the Department of Revenue. The form’s instructions are explicit: “Do not send them to us unless we specifically request them from you.”1Illinois Department of Revenue. Form IL-1000-E – Certificate of Exemption for Pass-through Withholding Deliver it before the entity runs its annual withholding calculation so the exemption applies to the correct tax year.
How Long It Lasts
Form IL-1000-E has no expiration date and does not need to be renewed each year. One signed certificate stays on file with the entity.1Illinois Department of Revenue. Form IL-1000-E – Certificate of Exemption for Pass-through Withholding
The Department of Revenue can revoke it, though. If the owner stops filing Illinois returns or falls behind on payments, the department can notify the pass-through entity that the certificate is no longer valid. The entity then has 60 days before it must resume withholding on the owner’s share. The entity may not accept a replacement certificate from that owner until the department clears it.
What the Owner Still Has to Do
Filing the certificate does not reduce the Illinois tax owed. It just shifts responsibility for paying it from the entity to the owner. Each year, the owner has to file the Illinois return that fits its entity type and report its share of the pass-through entity’s Illinois-source income. Corporations file Form IL-1120, partnerships file Form IL-1065, and trusts and estates file Form IL-1041. The tax is due on the same schedule as any other Illinois filer’s.
Falling behind creates problems on both sides. The department can revoke the certificate and force the entity to start withholding again, which is a compliance headache for the entity that accepted the certificate in good faith.
What the Entity Has to Keep
The pass-through entity must keep every IL-1000-E it accepts and produce it for the Department of Revenue on request.3Illinois General Assembly. Illinois Code 35 ILCS 5/709.5 – Withholding by Partnerships, Subchapter S Corporations, and Trusts The statute sets no specific retention period for the certificates, but Illinois generally requires businesses to keep tax records for at least three and a half years after filing the return that covers the period.4Illinois Department of Revenue. What Must I Keep in My Books and Records? Because the certificate stays in effect for as long as the owner receives distributions, the safer practice is to keep it for the full length of the relationship and for at least three and a half years after the last tax year it covered. Without a valid certificate on file, the entity has no defense against an assessment for the withholding it should have collected.
