Turn TIN Matching Results into a Follow-Up Queue

Match the response file or record to the submitted batch reference and frozen input version. Compare the number of submitted combinations with returned results and unresolved entries. A provider notification that a batch is complete does not by itself show that every row received the expected result.

Use the stable recipient key or documented row mapping to attach results. Do not join only by row order if the response can reorder or omit records. Keep any rejected file, parsing error or missing response outside the ordinary success count.

Preserve the original code and text before translating them into internal queue labels. A future reviewer may need the source meaning, especially if a provider changes its display terminology.

The IRS result-code table in IRM 3.42.8.7.4 describes nine codes. The actions below are our operational routing suggestions, while the code meanings come from the IRS.

Codes 6-8 relate to unknown TIN-type requests. They do not independently establish whether a supplier is an employee, corporation or other tax entity.

For an input error, assign the data owner the exact field problem and source reference. For a mismatch, provide the submitted name, protected identifier reference, documentation version and the question that needs answering. For a duplicate request, inspect the earlier event before generating another submission.

Use separate queue reasons such as source missing, formatting issue, identity clarification or response unavailable. These are internal labels, not replacements for the original IRS code. A single failed category can hide the difference between an incomplete request and a meaningful mismatch.

Set a next action and owner for each unresolved record. Avoid a queue that can be closed simply by changing a status dropdown without recording the document or corrected input that resolved the issue.

Fictional example. A team submits twelve documented combinations and receives twelve coded results. No real matching occurs here.

The result count reconciles: 8 + 1 + 2 + 1 = 12. The queue has four records needing follow-up, but only two are name/TIN mismatches. Calling all four mismatches would send the wrong message to the supplier whose problem was a local formatting error.

After correction, a new match event is linked to the earlier unresolved event. The team keeps both responses so it can show which input changed and whether the later result addressed that change.

A pre-filing match response is not the same document as an IRS CP2100 or CP2100A notice. The IRS notice guidance and Publication 1281 describe notice, solicitation and backup-withholding procedures.

Do not automatically send a formal B notice for every matching-system exception. At the same time, do not use this distinction to ignore a missing or obviously incorrect TIN or an actual IRS notice. Those facts can create separate duties that require prompt review.

Route those cases to the person responsible for withholding and formal notices with the actual triggering document and dates. The matching queue should link to that workflow, not guess its requirements from a provider's red icon.

A resolved queue item should link to the source clarification, final input version and resulting match event, or document why no further match was appropriate. Retain unresolved results explicitly when the issue cannot yet be completed.

A positive match does not certify payment amounts, filing thresholds, worker status or the accuracy of every field on a return. It also does not guarantee that an agency filing will be accepted. Keep those reviews separate while reusing the documented identity evidence.

The downloadable queue template preserves the raw code and the operational action. Use it to report how many records were submitted, matched, unresolved and assigned for other review, rather than reducing the entire process to a percentage that hides the remaining work.
