Several things change when you become a sub-contractor.  One of them is W-2s; you won’t have them anymore.  You will self-employed.   As a self-employed sub-contractor, you may (very likely) be asked to complete a W-9 when you are hired for a project.   On that W-9, you’ll give your name, address, and your social security number (or your employer identification number).  You SHOULD get a 1099-MISC if an individual or company pays you $600 or more.  That 1099-MISC will show your self-employed income earned.  Pay attention here – this is important!!!  Even if you don’t get a 1099-MISC, you still must report the income you’ve earned on each of your individual jobs or projects.  Do yourself a BIG favor; keep good records—from the very beginning.
