<prompt> Human: That seems ridiculously high for self-employment income. 15.3 payroll tax25 marginal income tax. How am I thinking about this wrong? I am a 1099 and not a W-2 for an online company. EDIT: assuming all my self employment income is above the 25 bracket I am a w-2 for income below my 25 bracket and my state and federal taxes are already paid through by me through my other employer  <response>: If it makes you feel better you may or may not have state tax to pay as well.
