Hello kiameshar. The answer to your question is very easy and comes under what the IRS defines as constructive reciept. Did you receive and/or have access to all of your income last year? When you receive a W-2 for income in Tax Year 2013 that is what your employer reports to the IRS as income paid to you, so yes, you are required to file each one of these W-2's with your 2013 Tax Return. I hope this helps.
