Avoid Rejections: Keep Form 5472 and 1120 Data Consistent
Many Form 5472 issues come from inconsistent data between the form and the attached pro forma 1120. A single source of truth eliminates this risk.
Data consistency
The most common mismatch areas
LLC legal name or address differences
EIN formatting errors
Tax year dates not aligned
Owner information inconsistent across forms
How to prevent mismatches
Store your LLC profile in one place and reuse it across all forms.
Avoid manual re-entry where possible.
Review both forms side by side before submission.
