Term 42 of 105 in the glossary, filed under F.IRS: instructions for Form 1120
Form 1120, for a founder abroad.
A C-Corporation reports its income, deductions and tax on Form 1120, at a flat federal rate of 21%. It's due on the 15th day of the fourth month after the company's year ends, which is 15 April for a calendar year, and Form 7004 gives six more months to file, though not to pay.
A corporation that's 25% or more foreign-owned attaches Form 5472 to it. A foreign-owned single-member LLC files a pro forma version as the cover for its Form 5472, with no tax calculated.
