<prompt> Human: I am 18 and as of May I have been trading Forex and have made it my main income. I have never had a job before so I will file my first taxes this coming April 2018. However I have just been informed that as a self employed person that I need to file quarterly payments of some sort not sure exactly but its called a 1040-ES now Im worried because I didnt do it for the 2nd quarter of 2017 and from what I read there is a penalty for not doing it I think it was 4 or a fine. I just want to know if it applies to me or not. Im not exactly sure how it works but from what I read I am suppose to give them an estimate of upcoming income which is very unpredictable because some weeks are amazing and some are just okay. Anyway for the first quarter I averaged about 800 weekly and I am slowly growing currently I am netting 1200 weekly so my income is slowly rising as I put my 65 profits back into forex. Since I am 18 and have no expenses other than my phone bill and cable bill which my parents have put me in charge of. How do I know if that form applies to me and how do I go about filing estimates when my income can vary weekly. Also what are other general fillings a self employed person must do besides the annual and quarterly because i really dont want to get i trouble with the IRS.SORRY FORGOT TO MENTION but I live in Las Vegas NV and from what i know we only have federal taxes we have no income taxes  <response>: Hmm, this is more complicated then being self employed. You probably need to get an accountant.
