@jamiemhornbaker - normally, the firm will withhold a certain amount (I think 10% is the requirement), but the impact on your tax return could be very different - higher or lower.
can you explain more of what you are really asking? did you receive a death benefit? did the firm explain whether or not they withheld taxes from the payment? are you trying to determine how much to pay as an esstimated tax payment?
just need more details.
