Hi Ivan,
I'm not a tax expert either, and that IRS description is not very specific on how to report the bought date when considering an Average cost accounting method. In the case of Average accounting Fund Manager calculates your basis off the average of all purchased shares prior to the sell transaction. This is also what it uses for reporting the bought date. In your example, I agree it would also make sense to report only from the date of your purchase after you sold all the original shares. It would also make sense to report the bought date based off a FIFO share accounting method, as that is how short/long term shares are determined, even when using Average cost accounting. I'm not sure which method is more right, and I suspect all 3 would be acceptable to the IRS as long as you properly categorize long versus short term gains/losses, and report the correct gain/loss.
If you would prefer your gains/losses to be itemized in greater detail, you can turn on the "Use Wash Sale Rules" option under "Options / Report Settings... / Capital Gains" if you have the Professional or Advisor version. When this option is turned on, the Bought column is only a single date. When you have a sell transaction that spans multiple purchases, you will get a line item in the Capital Gains report for each lot, so there is a unique Bought date on each line. In your example, you would get a bought date for the batch B shares you sold for the date you purchased them after you sold batch A.
