O.K., so DW and I are trying to figure out how much tax she is supposed to send the gubmit as a consultant. After using the different calculators, reading different sites, trying to figure out the IRS (ha!) we have values ranging from 50% of her money to all of it plus selling our daughter into slave labor. I am officially hyperventilating at this point. Can someone who's gone down this road help explain just how much you owe? Just some examples and a ballpark? We might be so screwed....
