CategoriesBusiness & Finance

1120 stands for U.S. Corporation Income Tax Return (IRS Form 1120), a tax abbreviation.

Federal income tax return for C corporations, which pay tax at the entity level at a flat 21% rate. Shareholders are taxed again on dividends, the so-called double taxation of corporate profits.

Example: The startup is a Delaware C corp, so it files a 1120 even though it lost money.

Usage notes

The flat rate replaced graduated rates of up to 35% starting in 2018. Calendar-year corporations file by April 15, a month later than S corporations and partnerships. Specialized variants include Form 1120-F for foreign corporations and Form 1120-H for homeowners associations.
