Instructions for Form CBS-1, Notice of Sale, Purchase, or Transfer of Business Assets

General Information

Who must file Form CBS-1?

This form is commonly known as a "bulk sale" notice. A bulk sale occurs when, outside the normal course of business, a business entity (seller or transferor) sells or transfers the major part of any of the following:

  • 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 provisions of the Retailers' Occupation Tax Act or the Illinois Income Tax Act. 35 ILCS 120/5j; 35 ILCS 5/902(d).

When a bulk sale occurs, the purchaser or transferee must file (and the seller or transferor may file) Form CBS-1, Notice of Sale, Purchase, or Transfer of Business Assets, to report the sale or transfer of assets to the Illinois Department of Revenue (IDOR).

When must I file Form CBS-1?

Form CBS-1 must be filed with IDOR at least ten (10) business days prior to the date of sale or transfer.

What if I fail to timely file Form CBS-1?

If Form CBS-1 is not filed in a timely manner, the purchaser or transferee shall be personally liable for the amount owed by the seller or transferor to IDOR up to the amount of the reasonable value of the property acquired by the purchaser or transferee.

What if the terms of the sale change after filing Form CBS-1?

If the terms of the sale change after filing Form CBS-1, an updated Form CBS-1 must immediately be submitted with the updated sales contract and financing agreement.

What do I do if the sale is not finalized?

If the sale is not finalized, submit a letter signed by the seller or purchaser explaining why the sale did not occur.

What needs to be submitted with Form CBS-1?

When submitting Form CBS-1, enclose a copy of the financing agreement and the sales contract, which shall include the following information:

  • a description of the property being sold
  • the amount of the purchase price or a statement of other consideration for the sale or transfer, and
  • the terms for payment of the purchase price.

The sales contract must be signed by both the seller or transferor and the purchaser or transferee.

When will IDOR issue a bulk sales release?

IDOR will issue a bulk sales release only after all taxes, penalties, and interest have been paid.

Specific Instructions

Step 1: Identify the business, business assets, or business property being sold or transferred

Complete all lines to identify the business or business assets being sold or transferred.

Note: If the seller or transferor is a disregarded entity, provide the Illinois Account ID number of the entity responsible for filing tax returns with IDOR.

If the entire business is not being sold or transferred, specify what is being sold or transferred.

If the entire business is being sold or transferred, the seller or transferor can update the business's registration information with IDOR via MyTax Illinois, available at mytax.illinois.gov. Using MyTax Illinois, the seller or transferor may close the tax accounts associated with the business being sold or transferred, close any registered locations, or register a new business or additional locations.

To close a location using MyTax Illinois:

  • Log in to your ST-1 account, and select "View More Account Options."
  • Under “Account Maintenance," select "Maintain Locations," and then click the hyperlinked Location Code next to the site you would like to close.
  • Enter a cease date for a closing date and submit your request.

If you need help, contact IDOR's Central Registration Division at 217 785-3707 or REV.CRD@illinois.gov.
