I was a plaintiff on a lawsuit and accepted a settlement offer that will send me a check within the next few months. It is over $600 so I assume the company paying will submit a 1099-MISC to the IRS. What % of the check should I set aside to cover these taxes? Also, is there any way to go ahead and pay the IRS the taxes on the check when I receive, so that it is kind of like taxes coming out of my paycheck?
