<prompt> Human: So this year Im set to earn 70K per year as a W2 employee and an additional 12-15K as a 1099 independent contractorI live in NYC, single, and get zero benefits... The last part is slightly painful since over 40 of my gross salary will be taxed and then I have to pay for my own benefits after. So my salary looks higher on paper than it actually is.I was told I could write off some of the taxes for the 1099 paycheck. I was curious how this works and if the amount I can write off is limited because most of my income is W2? Also, do I have to complete taxes twice?Thanks  <response>: Your 1040 will include both your W2 income on line 7 and your 1099 profit on line 12.The write-offs people may be talking about are deductions to your 1099 revenue that you can make on your Schedule C -- related to expenses you incurred in relation to making the 1099 revenue. The Schedule C takes your revenue, then subtracts your deductible business expenses, to arrive at your profit. Its that profit that then gets taxed for self-employment taxes on Schedule SE that goes on 1040 line 57. And its also that profit that gets income taxed, though you get to remove 12 SE tax amount on 1040 line 27 before you compute the income tax. So your filing will include Schedule C, Schedule SE and Form 1040; you dont file two form 1040s.
