What happens if you leave the Commission field blank?
@LMillsap1
On the brokerage report, is the cost basis $12,976 or is it $13,000?
If it is a transaction fee and not a commission, the cost basis will be $12,976. You would enter the Buy without a commission and a separate MiscExp transaction for the fee. You can assign a Category to the fee and it will show up in your report. You can decide whether you want the fee to affect the reported performance of the security.
If it is really a commission, the amount should be included in your cost basis, making it $13,000 and will reduce any capital gains taxes you owe. You should enter the fee in the Commission box. Commissions do not get a Category but you can see them in the Investment Transaction report.
