So, my bud had two sets of options he exercised for cash. The small one seems to have been taxed right, but the larger one was Fed taxed at 22% and likely should have been taxed closer to 34%. As a result, he thinks he owes close to $100,000 in additional fed tax.
Should he try to find some way to pay the extra tax now, or just wait until April to cut the big check?
Thanks!
