“Great tool! I would otherwise qualify for de minimis except for stupid tiny rebalancing dispositions and one money market account that was opened and closed in the same week (why?? Argh). Your calculator saves me from paying hundreds of dollars to a tax advisor to report dispositions with gains/losses of pennies, so, thanks!”
