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 must also be filed if the purchaser or seller is amending an original or a previously filed supplemental Form.8594 because of an increase or decrease. Form 8594 is a tax document required in certain business sales where the buyer acquires assets rather than stock or equity. As a rule, the starting point for your Arizona return is your federal adjusted gross income. Form 8594 is the Asset Acquisition Statement, which the buyer and seller must complete and submit to the IRS. Edit, sign, and share 8594 online.
