Both the seller and purchaser of a group of assets that makes up a trade or business must use Form 8594 to report such a sale. Form 8594 is treated as an information return and failure to file this form when required triggers a penalty under I.R.C.. §6721(a) and (b).Unless Seller elects the installment method or is eligible for the "open transaction" method, Seller must use the "closed transaction" method. You (or the purchaser or transferee) must complete Form CBS-1, Notice of Sale, Purchase, or Transfer of Business Assets. Form 8883 generally serves the same purpose as Form 8594, Asset Acquisition Statement.
