2 verifications about Form 1120 Form 1120 ×
“A calendar-year C corporation files its federal income tax return on Form 1120.”
The statement accurately describes the standard federal filing rule for a domestic calendar-year C corporation. IRS instructions establish that such corporations generally use Form 1120. Limited exceptions exist for corporations required or permitted to file specialized returns, but they do not materially undermine the ordinary rule.
“An S corporation files its federal income tax return on Internal Revenue Service Form 1120.”
S corporations generally file their federal returns on Form 1120-S, not Form 1120. IRS materials explicitly identify Form 1120-S as the “U.S. Income Tax Return for an S Corporation,” while plain Form 1120 is a distinct return generally associated with C corporations. Omitting the “-S” changes the form being identified and makes the statement incorrect.
