If you mean personal income taxes, you can file them any time after January 1, and they are due on or before April 15, unless you file for an extension. In USA, you may file personal income taxes beginning January 2 and the deadline is April 15 or the first business day thereafter.
It is generally subject to the same April 15 deadline. If you need to file a Form 1120, you must file it by the 15th day of the third month following the close of the tax year, which for most taxpayers is March 15. You cannot send this form to the IRS with your personal income tax return.
