FATCA Dry-Run & Reconciliation

We execute a full dry-run of your FATCA reporting and perform detailed reconciliations (tie-outs) before go-live — expanding sampling, validating schema/logic, checking GL tie-outs, fixing defects, and issuing a clear go/no-go recommendation.

Who it’s for

  • Reporting entities that completed Build & Configure and want assurance before live filings.
  • Teams seeking strong evidence (results, logs, reconciliations) for reviewers, Internal Audit, and RO certification.
  • Institutions aligning FATCA with QI and wanting consistent tie-out & defect handling across regimes.

Objectives of the dry-run

Expand Sampling

Scale up samples across classifications, account types, and edge cases to validate outcomes and controls.

Validate Consistency

Schema (XSD) checks plus cross-field and cross-system consistency; review of code sets and reference tables.

Prove Reconciliations

GL/tie-outs from source balances to 8966/local XML totals; exception log with root cause & fix path.

Scope of work

Sampling & Testing

  • Risk-based and stratified sampling
  • Re-performance of controls & reviewer checkpoints
  • Negative/boundary tests for critical rules

Schema & Logic Validation

  • XSD validation for XML outputs
  • Cross-field checks (TIN/GIIN, classifications, balances)
  • Lineage spot-checks & evidence completeness

Tie-outs & Reconciliations

  • GL / sub-ledger reconciliations
  • Totals by pool/classification vs. filings
  • Variance analysis & materiality assessment

Defects & Fixes

  • Defect register with severity/impact
  • Root cause & remediation owner/date
  • Retest results & acceptance criteria

Portals & Submissions (test)

  • Portal readiness checks
  • Test submissions where available
  • Query handling playbook

Corrections Readiness

  • Pre-agreed workflow for corrections/re-filings
  • Receipt/ACK handling & audit trail
  • Escalation & communication templates

How we work

  1. 1) Dry-run plan & data cut

    Agree sampling, materiality thresholds, and exact data cut; lock acceptance criteria with stakeholders/IA.

  2. 2) Execute tests & validations

    Run schema/logic checks, expand samples, and re-perform key controls; maintain live defect register.

  3. 3) Reconcile & remediate

    Complete GL/tie-outs, analyze variances, fix defects, and retest until criteria pass.

  4. 4) Read-out & go/no-go

    Reviewer-ready report, reconciliations pack, and a clear go/no-go recommendation — plus next-step plan.

Deliverables you receive

Dry-Run Results Pack

Sampling plan & outcomes, schema/logic validations, evidence checks with screenshots/logs.

Reconciliation Sheets

GL/tie-outs, pool/class totals, variance analysis, materiality & sign-off trail.

Defect Register & Fixes

Severity, root cause, remediation status, retest results, acceptance criteria met/not met.

Go/No-Go Memo

Formal recommendation with residual risks and mitigations for go-live.

Corrections Playbook

Pre-approved workflow for corrections/re-filings, ACK tracking, and query handling.

RO Brief Check (optional)

Short-form note to support the RO ahead of certification.

Options & combinations

  • Independent or with Internal Audit: Align sampling, ratings, and documentation to your IA methodology.
  • QI alignment: Run a coordinated dry-run across FATCA & QI to reuse reconciliations and evidence.
  • Automation add-on: Lightweight scripts/dashboards to repeat key validations & KRIs each cycle.

What’s next

Go-Live & Submission

Final filings, receipts/ACKs, authority queries; corrections if needed.

Handover & Certification Support

Operating handbook, training, RO brief check and certification support.

Voluntary FATCA Review (optional)

Independent, sampling-based review for added assurance.
