The IRS wanted me to list each and every stock transaction I made in 2007, with the name of the stock and number of shares, date purchased, date sold, cost, sale price and profit/loss. I did about 80 transactions last year! I'd have had to fill out 4 or 5 Schedule D-1's. Fortunately the instruction book says I can use a "statement" that provides similar information, and Gainskeeper was able to provide me with a PDF of all of last years sales. I hope the IRS will accept it; it's got all the same data as the D-1 requires, though the columns are in slightly different order (dates then name, rather than name then dates).
So I had to fill out the 1040, and Schedules B and D. No C or SE this year, since I didn't do any business activities this year.
I owe the IRS $250 and NE Dept of Revenue another $116. Damn but Nebraska state income tax is BRUTAL.
