Form 1120(redirected from 1120 Form)
A corporate tax return in the United States. A corporation files Form 1120 to report its revenue, expenses, and profits or losses. It also uses Form 1120 to claim deductions and credits, which is especially important in the United States because corporate tax rates historically have been high compared to other countries. Form 1120 generally is filed three months after the end of the corporation's tax year.
