A2A.Proceeds from real estate transactions are typically reported on Form 1099S.Form 1099B is typically used to report sales made by a broker normally stocksales. Im not sure why you would be getting a 1099B for a real estatetransaction so I assume you meant 1099S. How you report it depends on thetype of property you sold.If you sold a personaluse property you use Part II of IRS Form 8949 Salesand Other Dispositions of Capital Assets to compute the gain or loss. If thisis your personal home and you qualify for the capital gains exclusion youincorporate that on Form 8949. You then carry the information to Schedule DForm 1040 Capital Gains and Losses. You cannot deduct a loss on the sale ofa personaluse property.If you sold a property other than a personaluse property you use IRS Form4797 Sales of Business Property to report the sale. If you did not use theproperty in a trade or business but were holding it for investment theportion of the gain that represents recapture of depreciation is reported asordinary income and any remaining gain is carried to Form 8949 and Schedule Dand reported as capital gain. If you used the property in a trade or businessyou still report depreciation recapture as ordinary income and any remaininggain from the sale is treated as section 1231 gain. See IRS Publication 5442023 Sales and Other Dispositions of Assets for a full description of howto treat section 1231 gain.
