You can do it. A lot of people are doing that from years. If you're lucky, if you get audited or IRS will not ask you further paperwork, you will be fine. If in case you got audited or if they request further paper work that time you have to amend the tax return and have to pay the penalty with 25% interest. I am not suggesting you to do illegal thing because there is always bad consequences when you try to do anything illegal. "Just pay the penalty and stay in the safe side" my suggestion.
