IRS Filed Returns
Sometimes IRS doesn’t want to wait for you to act, so IRS will act for you. In some cases, IRS will fill out a return for you, using assumed numbers, and then calculate a tax (and penalty and interest) based on their assumed numbers…which are very often incorrect (and not in your favor!) It is very difficult to undo this once IRS files a return for you. You may lose many rights by relying on an IRS filed return.
