<prompt> Human: My employer gives me a check every pay period. Im not a W2 employee, more independent contractor, so I get paid per day not per hour. I get no benefits, all I receive is a check for: days worked X daily rate. I dont take a lunch break and I dont clock in or out. I filled out a 1099. My question is, what forms do I need to receive from him to do my taxes and since my checks dont take out Medicare, SS or other things, will I have a lot to pay come tax season? Thanks.  <response>: Youre looking at 12.4 for social security and 2.9 for medicare. If no federal taxes are being withheld you should have been filing estimated taxes quarterly. If you havent been paying quarterly there are underpayment penalties you may be subject to.Your tax burden is probably going to be more than you expect. Id try and figure it out now before you get obliterated in April.
