I had already filled out and sent in a tax return form for 2007. I only included one job on there, and that was the job I made $8000 at. I worked one job earlier in 2007 and made $824 total. I got the W-2 for the $824 job today and I had sent in my federal return about a week and a half ago but I had only included the job wherein I made $8000. Also bear in mind no money for federal taxes had been taken out of the $824 job, but some had been taken for Medicare and Social security. 1) Do I need to refile my federal taxes again in because of the W-2 for the job I did not include? 2) If I do not refile with the new W-2 included, will the IRS withhold my tax return or audit me?
