Bulk Sales Law Illinois

What Illinois requires today (IDOR Form CBS-1)

Many older “bulk sales act” summaries still describe UCC Article 6 creditor-notice regimes. Illinois practice for Main Street deals is dominated by tax bulk-sale notice through IDOR using Form CBS-1 (Notice of Sale, Purchase, or Transfer of Business Assets).

According to IDOR’s CBS-1 instructions, a bulk sale occurs when, outside the normal course of business, a business entity sells or transfers the major part of:

• stock of goods that it is in the business of selling; or
• furniture or fixtures, machinery and equipment, or real property of the business that is subject to the Retailers’ Occupation Tax Act or the Illinois Income Tax Act (instructions cite 35 ILCS 120/5j and 35 ILCS 5/902(d)).

• Who must file: the purchaser/transferee must file; the seller/transferor may also file.
• Deadline: at least ten (10) business days before the sale or transfer date.
• Attachments: signed sales contract (property description, price/consideration, payment terms) and financing agreement as applicable.
• Late/missing notice risk: purchaser/transferee can become personally liable for amounts the seller owes IDOR, up to the reasonable value of property acquired.
• Release: IDOR issues a bulk sales release only after taxes, penalties, and interest are paid.

City of Chicago bulk sales notice (separate calendar)

Chicago businesses may face an additional municipal bulk-sales notification requirement. City guidance requires notice no less than 45 days before certain sales/transfers of a business or major part of assets tied to City tax/licensing obligations. Failure to file timely can leave the purchaser jointly liable for unpaid prior City tax. City materials direct filers to submit the Bulk Sales Notification Form with the sales contract (and power of attorney if represented) to the Department of Finance bulk sales channel published on the City site.

Deal-calendar implications

1. Counsel decides whether the APA asset transfer is in scope for CBS-1 and any local notices.
2. Build IDOR’s 10-business-day lead time (and Chicago’s 45-day lead time if applicable) into exclusivity and closing conditions.
3. Do not market a “two-week close” that collides with notice windows unless counsel documents a risk plan (often escrow/holdback—not skipping filings).
4. Coordinate MyTax Illinois account updates, final returns, and buyer registration with your CPA.
5. Track UCC lien payoffs in parallel—bulk sales notice is not a lien search.

Common misconceptions

• “Bulk sales was repealed, so we ignore tax notices.” — Tax bulk-sale notice under Illinois law can still apply; use IDOR materials, not folklore.
• “Only the seller files.” — IDOR places a filing duty on the purchaser/transferee.
• “Stock sales never care.” — Structure still needs counsel review; do not assume.
