<prompt> Human: According to page 2 of this IRS document for 2014, if a person is single, under 65, and has made less than 10,150 for the year, then they do not need to file a return. So, should this kid who lives with his parents and has been cutting grass as his main source of income make estimated tax payments, knowing full well he is not going to even come close to the 10,150?I spoke with an paid for it a tax expert who said that if you earn over 650, then you MUST file for taxes and pay a self-employment tax. Is that true? When you do an odd-job for someone or lots of odd-jobs for lots of people, is that considered self-employment or miscellaneous income?  <response>: IRS employee here: a tax expert who said that if you earn over 650This is incorrect. Dont ask a plumber to fix your car.Thank you for reading.
