The IRS also will fax commonly used forms and instructions to you. You can get forms at many post offices, public libraries or local IRS offices. It's open 24 hours a day through April 16.
Refund information is updated weekly.
But wait at least 4 weeks after you've filed. Use Form 4868 to get an automatic 4-month extension for filing your forms. Tax preparation software provides an e-filing option for extensions, and, starting next month, the IRS will begin taking extension notifications by phone. You still must pay your tax by April 16 to avoid interest charges.
