Quote from JackR:
That's the way it used to be.
Last year the IRS stated they wanted all detail. There was much discussion and you might do a search on ET.
Another acceptable approach, but you will not be able to file electronically, is to prepare an Excel spreadsheet with the columns laid out in the Schedule D format. Carry the Excel total to the appropriate line on Schedule D and make reference to the Excel attachment on the Schedule D.
Here are two extracts from the 2006 Schedule D Instructions:
Do not enter "available on request" and summary totals in lieu of reporting the details of each transaction...."
.....
Like an investor, a trader must report each sale of securities (taking into account commissions and any other costs of acquiring or disposing of the securities) on Schedule D or D-1 or on an attached statement containing all the same information in a similar format.
