1094-C Aggregated Group Reporting: Prepare the Entity Facts

Ask the responsible reviewer to identify the reporting ALE member, the other relevant entities, and the periods for which they were part of the applicable aggregated group. Record legal names and secure EIN references, along with transaction documents or other evidence supporting changes.

The IRS ALE determination guidance explains that related-employer rules can affect ALE status. The form preparer needs the result of that review, not an independent guess based on shared benefits or a common payroll provider.

Keep entities that merely share a service provider distinct from entities actually determined to be group members. Also flag organizational changes that need review rather than assuming an acquisition date always produces the same reporting treatment.

The 2025 Form 1094-C presents the group question in Part II and the supporting detail in Parts III and IV. Review them as one connected set.

Under the 2025 definition, membership on any day of a month makes that a membership month. Preserve the exact effective date even when the final form uses a monthly indicator.

Fictional Alder Basin Services is the reporting ALE member. Its tax reviewer determines that it joins the applicable aggregated group with Birch Basin and Cedar Basin on July 18, 2025. The example assumes that determination is complete and all three named companies are relevant ALE members.

Line 21 is reviewed as “Yes” because the year contains membership months. Part IV for Alder Basin considers the other members, Birch Basin and Cedar Basin, rather than listing Alder Basin as its own other member.

The six membership months do not imply that the relationship began July 1. The source timeline retains July 18, while the monthly reporting follows the instruction's any-day rule.

Maintain the complete reviewed list before reducing it to the form's available entries. The 2025 Part IV instructions call for up to 30 other members, exclude the reporting member, and specify selection and descending-order rules based on average monthly counts. They also provide a different count basis when a group member uses the 98% Offer Method.

Have the reviewer document the applicable ranking basis and period. Keep the underlying counts with the full entity list, especially when there are more members than the form can list. Do not simply take the first 30 names alphabetically.

Compare legal names and EINs to verified entity records. A familiar shortened business name may be useful in an internal dashboard but should not replace reviewed identity data in the prepared form.

Compare the year-level answer, monthly indicators, and other-member list against the same approved timeline. A “No” response paired with populated group details, or all-year markings after a midyear membership start, calls for review.

Distinguish the reporting employer's membership months from each other entity's entire corporate history. The group register can contain more detail than the form; the preparer must apply the field's scope to the reviewed facts.

When a source date changes, revisit all related fields and any affected employer packets. Keep the original determination and revised explanation rather than silently replacing the organization chart and losing the reason earlier forms differed.

Retain the legal review or determination reference, entity identities, effective dates, monthly map, and Part IV ranking support. Record the actual reviewer and the prepared output version. The employer approver should know which facts were confirmed and which questions remain unresolved.

Use the downloadable entity-month worksheet to assemble the packet. Its first row identifies the reporting member so that member is not accidentally included in the list of other members. Its ranking fields make the selection process reviewable.

If a corporate relationship remains unclear, collect the documents and ask the designated reviewer to resolve it. The correct next step is a factual determination, not a guessed checkbox chosen to make the form look complete.
