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.
Generally, the due date for filing your tax return is April 15 following the close of the tax year. If April 15 falls on a weekend or holiday, the due date for filing your tax return is the next business day. Fiscal-year tax returns are due by the 15th day of the fourth month after the close of the fiscal year. (ie: Fiscal year end date July 1, returns are due November 15). You must complete the Fiscal Year date at the top of the income tax form you're filing.
