Gross sales price refers to the total amount of consideration received by the taxpayer for the sale of capital assets, including any commissions or fees paid to brokers. Net sales price, on the other hand, is the gross sales price reduced by any allowable deductions, such as sales taxes, transfer taxes, and certain closing costs. The net sales price is used to calculate the taxable gain or loss on the sale of the capital asset. Form 2438 requires taxpayers to report both the gross sales price and the net sales price for each sale or exchange of a capital asset.
