<prompt> Human: My wife has gotten a new job as an independent contractor, which means we are responsible for our own taxes. I have looked all around the internet for advice on what to do, but come up with a lot of different answers. Is there anyone else who is paid as an independent contractor who could help? I am great with numbers and dont mind doing the calculations and everything, I just do not know the numbers I need to use. Thank you all so much!  <response>: This post is among those from utaxmankeith and it has a good list of IRS publications that can be useful.link hereYou can include both regular job info W2 work and contractor job work 1099 on one Form 1040. Use Schedule C to report the contract income and also to get any legitimate business related deductions. Consult the references about that. Result goes on 1040 line 12.Use Schedule SE to compute self employment tax, which supports Medicare and Soc Security. This is the tax that is normally split 5050 with an employer. Its about 15.3 of a certain percent of net business income. So you need to have completed Schedule C first. The result of Schedule SE goes on 1040 line 57, but you can also deduct half of the SE tax on line 27 so dont forget that.For people who file and have withholding from some jobs but not from self-employment, the IRS has rules about whether they need to be making quarterly estimated payments. Sometimes the withholding is enough. Sometimes not, depending on how much the contractor income is. If thats the case, youre supposed to send the IRS money by deadlines in April, June, September, and January. See Form 1040-ES for the rules about whether estimated taxes are required and how to compute the amount the IRS expects. At tax time you reconcile, so if you overestimated income, and sent in too much, you get a refund.
