Form 1099‑SB reports the gross proceeds from the sale or exchange of a business, including a partnership interest, corporation stock, or other business assets. File it when you are the seller or the broker handling the transaction.
Plain English
If you sold a whole business or a big chunk of it, the IRS wants to know how much money changed hands. This form tells the government the sale price, so the buyer and seller both stay on the right side of tax rules. It’s not for selling a personal home or a single piece of equipment.
