A taxpayer can obtain an additional six-month extension of time to file its tax return. A corporate taxpayer is required to file an annual tax return (generally Form 1120) by the 15th day of the fourth month following the close of its tax year. The US tax system is based on the principle of self-assessment and voluntary reporting. New corporations may use a short tax year for their first tax period, and corporations may also use a short tax year when changing tax years. Corporate taxpayers may choose a tax year that is different from the calendar year. US corporate taxpayers are taxed on an annual basis.
