If you can get (the balance) paid by the due date of your return plus extensions, don't do it.

The AMT is an entirely different way to calculate your taxes, and it's not really an alternative, as the name suggests. You have no choice. And it's affecting more and more people all the time.

You're going to need all that information to determine cost to calculate your gain or loss at a later date.

Once you've done the sale, the only way to fix that is with a time machine. But you can take steps to minimize the (tax) impact.

Lower taxes are great, but if its going to cost you money, it's not worth it. If a stock hits your sell range after 3 months, do you really want to risk 9 more months of fluctuation to get a lower tax rate?

Your guess is as good as mine.
