You cannot deduct a fee you pay to a broker to acquire investment property, such as stocks or bonds. You must add the fee to the cost of the property. See Basis of Investment Property in chapter 4. You cannot deduct any broker’s fees, commissions, or option premiums you pay (or that were netted out) in connection with the sale of investment property. They can be used only to figure gain or loss from the sale. See Reporting Capital Gains and Losses, in chapter 4, for more information about the treatment of these sale expenses.
