FATCA corrections & re-filings — practical workflows and evidence
Corrections are inevitable: late documents, GIIN changes, TIN/Name hygiene, or mapping fixes. This playbook shows a repeatable workflow and the evidence to keep so corrections pass audit and reviewer checks.
Scope: Form 8966 (Model 2 / some Model 1 via local portal), Form 1042-S, and local IGA filings. Keep a centralized Corrections Log and Refiling Tracker.
1) When to correct vs re-file (quick rules)
- Data errors (Name/TIN, GIIN, residence, amounts): file a correction using the same record key the platform expects.
- Omissions (missed accounts/recipients): submit additional records and log the reason.
- Schema/process errors (bad version, invalid TCC, rejected file): re-file batch after fixing the root cause.
- Nil returns: follow portal rules; corrections may still be required if metadata was wrong.
2) Standard workflow (5 steps)
- Identify issue & root cause (late docs, mapping bug, onboarding hygiene).
- Prepare corrected dataset: maintain a Before/After diff per record.
- Validate against the correct schema; dry-run if your platform supports it.
- Submit correction/batch; capture Submission ID/receipt and any error report.
- Close the loop: update logs, evidence, and impacted processes; communicate to stakeholders.
3) Evidence pack — what to keep
- Corrections Log with Before/After, error code/description, owner, due date, status, and receipt.
- Refiling Tracker for batch submissions: counts accepted/rejected and next actions.
- Receipts & error reports (portal confirmations, PDFs/CSVs, hashes if provided).
- Root cause memo for material issues; track remediation action and validation evidence.
4) Controls that reduce re-work
- Schema/version lock in build pipeline; sample validation before every submission.
- Name/TIN hygiene routines; GIIN monthly match (see GIIN tracker).
- Maker-checker for corrections; approvals captured in the log.
- Post-mortems for rejected batches; fix mappings and re-run validations.
