86 Ill. Adm. Code 130.430
Deposit or Prepayment on Purchase Price
Section 130
Section 130.430 Deposit or
Prepayment on Purchase Price
a) If a buyer in a sale at retail makes a binding commitment to
purchase, and the tangible personal property which is the subject of the
binding commitment has been identified to the contract, any payment on the
purchase price must, at the time of such payment, be included in the measure of
the seller's tax liability. Tangible personal property is identified to a
contract pursuant to the standards set forth in Section 2-501 of the Uniform
Commercial Code Sales (Ill. Rev. Stat. 1989, ch. 26, par. 2-501). The giving
of the binding purchase order by the purchaser, identification of the tangible
personal property and the making of a payment on the price are sufficient to
establish that a sale is intended for the purpose of determining that the
seller has received taxable "gross receipts".
b) After the seller has paid Retailers' Occupation Tax on the
amount of such payment on the price, if the transaction is rescinded and the
seller refunds such payment to the purchaser, the seller is in the same
position as when he makes a refund on account of the return of merchandise
after having paid Retailers' Occupation Tax on the amount so refunded and so
may take a deduction on his return for the return period in which such a refund
is made.
