When you don't file a tax return, the Internal Revenue Service does it for you. You may wonder if that's a bad thing, as you don't have to do all the work. The IRS files the tax return with only the information it has on hand, so you miss out on valuable credits and tax deductions by not doing it yourself. You may even end up owing a balance on your taxes, and the IRS will begin collection proceedings on it. If you failed to file your taxes for a year, it's not too late to file. The IRS amends any returns it substituted with your new tax return document.
