<prompt> Human: Hi all,I just survived my first year of full employment out of college and was surprised with a generous bonus. I knew Id lose about 25 of it to taxes but when i got the deposit, about 36-38 of it was withheld even though Im in the 25 bracket. The bonus was deposited as a separate deposit from my normal check.Ive tried researching why this is but Im still confused and tax law is not my area of expertise.Why is this so?  <response>: I think the normal method for bonus withholding is a flat 25 for federal taxes. Then 7.65 for Social Security and Medicare. The other 6 is probably statelocal taxes.
