text: how do you calculate the amount they take out for taxes if you claim "0" on your paycheck? im in wisconsin. any website that can calculate this for me or any one know about this? check out www.paycheckcity.com they have paycheck calculators.  make sure when you get to the area to put the amount in, you change the state near the top.  i use it frequently for myself and clients so they know the best number to claim.
