Oscar Oppressed consults you regarding his tax problems. Oscar tells you that he has not paid the $20,000 balance due on his 2008 income tax return. He had sent some information to the Collection function of the IRS showing them that he had no money aside from the wages he earned as a janitor at the local packing plant. Oscar mailed in the information approximately six months ago and heard nothing further until he went to pick up his paycheck last Friday. The paymaster informed him that they had received a levy and had paid over the amount of his check to the IRS. (A) Is the levy proper? (B) Can the IRS take Oscar's entire check or must they leave something for Oscar and his three minor children to live on?
