Prior-Year Form 1120 Dates and Continuous Form 5472 Revisions: Read Them Differently
· 6 min read
The practical answer
A year printed on an annual return and a revision date printed on another form do not necessarily describe the same kind of period. Identify what each date means before treating a downloaded file as the correct version for an earlier filing year. Three details shape the review: Is the printed date a tax year or a revision date? Which period is the filing intended to cover? What supports using that version for that period?[1, p.1] [2, p.1] [3, p.1] [4, p.1] [5, p.2]
Scope and the records behind the answer
The discussion follows the entity, form and transaction conditions identified below. The same label on a different form can have a different purpose. Keep the relevant entity and reporting period visible while you compare the requirements, and treat each stated exception as part of the rule rather than an optional footnote.
Official sources checked: 2026-11-09. Annual tax-year forms and continuously revised forms are identified separately in the references.

| Form1120 year 2023 | The official 2023 Form 1120 identifies calendar year 2023 or a tax year beginning in 2023. | Annual Form 1120 tax year only; continuous Form 5472 revision applicability must be checked separately. | [2, p.1] |
| Form1120 year 2024 | The official 2024 Form 1120 identifies calendar year 2024 or a tax year beginning in 2024. | Annual Form 1120 tax year only; continuous Form 5472 revision applicability must be checked separately. | [3, p.1] |

Work through the official requirements
Form1120 year 2022
The official 2022 Form 1120 identifies calendar year 2022 or a tax year beginning in 2022.[1, p.1]
This applies when: Annual Form 1120 tax year only; continuous Form 5472 revision applicability must be checked separately.
Form1120 year 2023
The official 2023 Form 1120 identifies calendar year 2023 or a tax year beginning in 2023.[2, p.1]
This applies when: Annual Form 1120 tax year only; continuous Form 5472 revision applicability must be checked separately.
Form1120 year 2024
The official 2024 Form 1120 identifies calendar year 2024 or a tax year beginning in 2024.[3, p.1]
This applies when: Annual Form 1120 tax year only; continuous Form 5472 revision applicability must be checked separately.
Form 5472 continuous revision 2021
The archived Form 5472 is marked Rev. December2021 and separately provides blanks for the reporting corporation’s tax year.[4, p.1]
This applies when: A revision date is not an annual-tax-year label; do not infer applicability to a particular delinquent year solely from the filename.
De tax year
A foreign-owned U.S. DE uses the tax year its owner uses for U.S. tax filing. If the owner does not have such a tax year, the DE uses a calendar year.[5, p.2]
De proforma required
A foreign-owned U.S. DE subject to Form 5472 filing attaches Form 5472 to a pro forma Form 1120 and files by the Form 1120 due date, including a valid extension.[5, p.2]
Field/section Part VI attachment: Nonmonetary and Less-Than-Full Consideration Transactions
Check Part VI and attach the description of foreign-related-party nonmonetary or less-than-full-consideration transactions. Do not omit them merely because they do not fit a cash-payment category.[6, p.2] [5, p.6]
Field/section Top annotation: Foreign-owned U.S. DE
Write "Foreign-owned U.S. DE" across the top of the pro forma Form 1120 to identify this special filing.[5, p.2]
Field/section Name: Name
Enter the foreign-owned U.S. DE's name.[7, p.1] [5, p.2]
An illustrative preparation scenario
In this hypothetical preparation example, a preparer finds an annual Form 1120 for an earlier year and a Form 5472 carrying a revision date. The review records each document's version information separately and checks applicability for the intended period instead of forcing both dates into the same tax-year label. The preparer checks three points: Is the printed date a tax year or a revision date? Which period is the filing intended to cover? What supports using that version for that period? The file remains a working comparison until the relevant facts and applicable instructions have been checked together. No agency outcome is assumed.[1, p.1] [2, p.1] [3, p.1] [4, p.1] [5, p.2]
This is a planning illustration, not a statement that a particular filing has been accepted or that an entity qualifies for a tax result. Use the source-backed distinctions above to decide what information still needs to be established before a form is completed.
A review sequence you can actually use
- Is the printed date a tax year or a revision date?
- Which period is the filing intended to cover?
- What supports using that version for that period?
Write down the answer and the record that supports it, rather than marking a question complete because a field contains text. When two records disagree, identify whether the difference concerns the entity, an individual, the reporting period or the type of change. That makes the remaining question specific enough to resolve against the relevant instruction.
Keep the scope of a preparation service separate from the government requirement. A service intake question may gather information for a workflow; it does not create an exception, extend a deadline or determine whether a transaction is reportable. The cited government material remains the basis for those conclusions.
Questions to settle before moving forward
How should I check form1120 year 2024?
The official 2024 Form 1120 identifies calendar year 2024 or a tax year beginning in 2024. Annual Form 1120 tax year only; continuous Form 5472 revision applicability must be checked separately.[3, p.1]
How should I check form 5472 continuous revision 2021?
The archived Form 5472 is marked Rev. December2021 and separately provides blanks for the reporting corporation’s tax year. A revision date is not an annual-tax-year label; do not infer applicability to a particular delinquent year solely from the filename.[4, p.1]
How should I check de tax year?
A foreign-owned U.S. DE uses the tax year its owner uses for U.S. tax filing. If the owner does not have such a tax year, the DE uses a calendar year. [5, p.2]
How should I check de proforma required?
A foreign-owned U.S. DE subject to Form 5472 filing attaches Form 5472 to a pro forma Form 1120 and files by the Form 1120 due date, including a valid extension. [5, p.2]
