This is the amount you receive from the sale of an asset. Your broker or mutual fund company will send you a Form 1099-B or a substitute statement. The document will list the sales price of mutual fund and stock shares you sold during the year. By law, your broker or mutual fund company must send you a 1099-B by Feb. 15, 2013.

The amount shown on the 1099-B is the total amount you enter on your return for that particular sale. The IRS checks to see if the amount you reported is the same as the amount your broker or mutual fund company reported directly to the IRS.

Most 1099-Bs report the net sales price -- the gross amount minus commissions and other expenses. Your broker or mutual fund company will tell you on the form if the amount reported is the gross sales price or the net sales price. The gross sales price includes commissions and other expenses.

If the gross sales price is reported:

1. Enter the amount on the form.
2. Adjust the mutual fund’s cost by adding to it the sales commissions or expenses you paid.
