All of us have our own methodology when it comes to tax season. Some of us haul out a thick stack of documents and receipts, and then attempt to sift through it all. Some turn everything over to an accountant and hope for the best. But regardless of whether you itemize or not, your tax documents could be a gateway to identity theft if you're not careful. From stolen mail to dumpster dives, this is a popular season for criminals to go after you. In addition, you'll need to hang onto certain documents just in case you're audited at some point down the line. As you go through all the forms, we'll give you a better idea of what should (and should not) head straight to the shredder.
