C Corporations and S Corporations. C corporation and S corporation business owners are required to file their income tax returns on the 15th day of the third month after the end of the tax year. For calendar-year corporations, the return is due by March 15.
Every corporation, whether taxed as a C or S corporation, must file annual tax returns and pay the appropriate amount of tax, if any, by the same deadline. Your corporation is still subject to this deadline, even if it has a net loss for the year and doesn't owe tax.
