<prompt> Human: Hi, this is my first time on a 1099 starting a new job and would really like the help in figuring out what my annual salary comes to.-I am 25 and will turn 26 this November and from what I understand, I will need to pay my own benefits. I am currently on my parents.-The offer is 45hr which is roughly 90,000 annual.-No benefits  <response>: You can estimate things.But I should point out that if you are self employed there are some deductions you can take on page 1 of your Form 1040:line 27 -- Deduct an amount equal to half of your self-employment taxes Soc Security and Medicareline 28 -- Deduct contribution to a tax advantaged retirement plan, such as a Solo 401k where you can defer 18K as employee and another amount, possibly 20 of SE profit 12 SE tax, as employer of yourselfline 29 -- Deduction for health insurance premiums, also subject to some limitationsSo as you make projections for 2017, include plausible values if you will take advantage of any of those.---Assuming no line 28 or 29 deductions ... Here is some thinking about 2017. Your 2016 tax will be a lot less.Schedule C-EZ: profit is 90000 if you have no business deductions. Put on 1040 line 12.Schedule SE: These taxes will be Sched C-EZ profit 0.9235 0.153 12717. Put on 1040 line 57. Also use half, 6358, on 1040 line 27.Form 1040: AGI would be 90000 6358 83642. If you are Single and not a dependent, then taxable income would be 83642 AGI 6300 standard deduction 4050 personal exemption 73292.There are formulas in 1040-ES booklet to get an idea of tax on this. The 83292 gets divided into chunks.9275 is taxed at 10 927.5028375 is taxed at 15 4256.2535642 is taxed at 25 8910.50So without any deduction for health insurance, federal taxes are likely of this magnitude:14094 federal income tax12717 social security and Medicare taxesThats 2681190000 29.79 effective combined taxes.The amount of estimated tax to pay by each of the four deadlines would depend on your tax in the previous year. All you are asked to send in is the lesser of 100 of previous total tax or 90 of the upcoming years total tax 24130. If the latter is the lesser number, then pay in 6033 by deadlines in mid-Apr 2017, mid-Jun, mid-Sep, and mid-Jan. Then the remaining 10 2680 mid-Apr 2018.If you want to think of after-tax amount, 90000 26811 63189. Think about 5265month. But that is not counting retirement plan deferrals or health insurance premium deduction, and is ignoring state taxes.
