<prompt> Human: My taxes are fairly simple, I have 4 income streams this year - W2 59k, dividend 287, capital gainslosses unclear atm, and the 1099. The 1099 totaled 480 box 7, nonemployee compensation, but the live refund estimate calculation jumped from owing 52 it was at this figure after having input only the W2 and dividend income to a staggering 232. 180 on 480 of income just doesnt sound right to me, even considering nothing was withheld. Can anyone explain?  <response>: Sounds reasonable; certainly within the right ballpark. You need to pay income tax at your marginal rate, plus self-employment taxes.
