X12 105 — Business Entity Filings

The 105 carries business-entity filings (formation, amendment, dissolution) to a state or federal registration authority in the United States.

Purpose

The 105 documents filings submitted to a state register (Secretary of State, Corporations Bureau) to open, amend or dissolve an entity — corporation, LLC, partnership, non-profit. It carries the filer identity, filing type, officers and addresses, and attachments (articles, dissolution certificate).

It is used in Secretary-of-State e-government programs that accept EDI filings: the 105 is the structured equivalent of paper filed at the counter, and it is typically acknowledged by an 824 (Application Advice) on rejection, or by a return certificate.

Envelope structure

The 105 travels within the three X12 envelope levels (ISA/IEA, GS/GE with functional group BB, and ST/SE). Didactic example in release 004010:

Common segments

  • Header — ST, BGN (Beginning Segment), DTM (effective date).
  • Filer — N1*FF (Filing Filer), N3/N4 (address), PER (contact).
  • Officers — repeated LX loop with N1 (officer), PER.
  • Filing items — LX + REF (filing type), DTM.
  • Attachments — PWK (Paperwork) for non-EDI documents.
  • Summary — SE.

Common pitfalls

  • Filer identifier: the N1*FF must carry a consistent EIN or state identifier; missing EIN drops the filing into a paper queue.
  • Binary attachments: articles and certificates stay outside EDI; PWK references a document served by URL or portal, not an embedded binary.
  • Filing code: each state maintains its own filing-type code list; without prior alignment, the return 824 rejects the 105.

Documentation

The code 105 and the name Business Entity Filings are public and listed on x12.org/products/transaction-sets. The complete structure of loops, qualifiers and code lists is distributed by DISA via the proprietary Implementation Guides (TR3). ediverse.io covers only public concepts, the envelope and didactic examples.
