Common Reporting Standard – Marshall Islands

CRS reporting in the Marshall Islands requires Reporting Financial Institutions to submit reportable account and controlling person information in the OECD CRS XML format, aligned to Marshall Islands–specific submission and validation requirements.

Competent Authority

Ministry of Finance (Republic of the Marshall Islands)

Submission Method

Electronic submission via the applicable Marshall Islands CRS/AEOI reporting channels (upload of CRS XML files), in line with the local reporting process.

Reporting Format / Schema

OECD CRS XML (Custom CRS schema v.2 - MDES) - Individual XML per country

Deadlines & Timelines

- CRS deadline: typically 30/06
- Reporting is submitted annually for the relevant reporting year.
- Submissions should be completed by the applicable CRS deadline, with corrections submitted as needed after initial filing.
- Late submissions or repeated errors may trigger follow-up actions by the competent authority.

Common Pitfalls

  • TIN quality and completeness issues

    Missing, invalid, or incorrectly formatted TINs for account holders or controlling persons can lead to validation failures or remediation requests.

  • Entity classification errors (FI vs Non-FI / Passive NFE)

    Misclassifying entities can cause incomplete controlling person reporting and incorrect account treatment, especially in layered structures.

  • Controlling person data gaps

    Incomplete controlling person details (residence, DOB, address, TIN) is a frequent cause of rework for Passive NFE structures.

  • Residence/jurisdiction mismatches and country code issues

    Inconsistent tax residence declarations or incorrect ISO country codes can fail business-rule checks and require correction cycles.

  • XML schema and business-rule validation failures

    Files may pass schema checks but fail business rules (invalid codes, missing mandatory elements, inconsistent values), leading to rejection or resubmission.

  • Duplicate reporting and correction handling

    Re-submitting previously reported accounts without correct correction logic can create duplicates and complicate reconciliation.
