What Luxembourg financial institutions must report
Luxembourg and the United States signed a Model 1 intergovernmental agreement on 28 March 2014, implemented by the Luxembourg law of 24 July 2015. Luxembourg reporting financial institutions report their US reportable accounts — and the payments made on them — to the ACD in XML by 30 June of the following year; the ACD forwards the information to the US Internal Revenue Service.
GIIN and filer category
Each reporting FI, sponsor and intermediary is identified by its GIIN and its FATCA filer category.
US persons and owners
US TINs for individuals, and the substantial US owners of passive entities.
Balances and payments
Year-end balances plus dividends, interest, gross proceeds and other payments.
Amendments and voids
Records already accepted are amended or voided by reference, never simply sent again.
From your data to the ACD’s answer, in five steps

Import
Excel files from custodians and transfer agents, or FATCA XML files already filed with the ACD.

-

The FATCA XML is validated against the ACD schemas before you can download it.
-

Fund XP transmits your files to the ACD as depositor.
-

FATCA details checked before the file leaves
One panel lists the problems of the whole report; one click opens the account on the right field.
GIIN format
Typed with its capitals and its dots placed automatically, in the shape XXXXXX.XXXXX.XX.XXX.
US persons
US TINs, US residence and the substantial US owners of passive entities, checked field by field.
Sponsored entities
Sponsors and intermediaries carry their own GIIN and filer category.
Payments
By type — dividends, interest, gross proceeds and other — in the account currency.
Why a FATCA filing is rejected
In most cases the account data is sound and the file structure is not.
| Cause | What happens |
|---|---|
MessageRefId reused | Each message carries an identifier unique to the sender. Reusing one from a previous filing has the whole file rejected, however sound the data. |
DocRefId not unique | Every record carries its own identifier, unique over time and never reused. An export regenerated without renewing them fails. |
Amendment without CorrDocRefId | An amendment has to name the record it replaces. Without that reference it is treated as a new account, and the holder ends up reported twice. |
| GIIN with the letter O | A GIIN never contains the letter O. What looks like one is the digit zero, and the check fails on it. |
| GIIN not issued or lapsed | A well-formed GIIN that the IRS FFI List does not carry, or carries no longer. |
| Missing US TIN | A US reportable account with no TIN, where the agreement expects one or an explicit code in its place. |
| No nil report | A reporting FI with nothing to report still files. Silence is not a return. |
You change the data — the platform writes the FATCA record
The platform keeps the history of every record sent and accepted, and sends what the ACD expects for each change.
| What you do | What is filed with the ACD |
|---|---|
| Report accounts for the first time | New records, DocTypeIndic FATCA1 |
| Change an account already accepted | Amended record, FATCA4, referencing the accepted one |
| Delete an account already accepted | Void record, FATCA3 |
| The reporting FI’s details change | Sent with the next amendment or new-data file |
| Nothing to report for a reporting FI | A nil report in the ACD format |

FATCA reporting in Luxembourg — frequent questions
What is the deadline for FATCA reporting in Luxembourg?
FATCA reports are filed with the ACD by 30 June of the year following the reporting year — for example by 30 June 2027 for the 2026 reporting year.
Who has to file a FATCA report with the ACD?
Luxembourg reporting financial institutions under the law of 24 July 2015 implementing the Luxembourg–US intergovernmental agreement, including investment funds, unless they qualify as non-reporting or deemed-compliant institutions.
Does the ACD send the FATCA reports to the IRS?
Yes. Under the Model 1 agreement, Luxembourg institutions report to the ACD, which exchanges the information with the IRS.
How do I correct a FATCA record already accepted?
Edit the account in the platform. It sends an amended record (FATCA4) or a void record (FATCA3) referencing the accepted one, in its own file.
Can sponsored entities be reported?
Yes. A reporting FI can have a sponsor and an intermediary, each with its GIIN and filer category, reported in the FATCA file.
Does the platform also handle CRS?
Yes. CRS and FATCA reports are prepared in the same project. See CRS reporting in Luxembourg.
