What Luxembourg reporting financial institutions must file
Under the Luxembourg law of 18 December 2015 on the automatic exchange of financial account information, reporting financial institutions report each year the financial accounts held by residents of reportable jurisdictions. The report is filed in XML with the ACD by 30 June of the following year; the ACD then exchanges the information with the tax authorities of the jurisdictions concerned.
Strict ACD XML formats
The ACD envelope, the CRS message and the file naming rules: a file that deviates is rejected.
Corrections, record by record
Changes and deletions must reference the record accepted before, with DocTypeIndic OECD2 and OECD3.
Reportable jurisdictions
Only the jurisdictions on the Luxembourg list for the year are reported, and that list changes over time.
Many entities, one deadline
Funds, sub-funds and clients, with data from several sources, all due by 30 June.

Every CRS error found before the ACD finds it
Live checks on every field the ACD requires: TINs and their usual format by country, residences, addresses, account types, controlling persons. One panel lists the problems of the whole report; one click opens the account on the right field.
Year on year
Accounts reported last year and missing this year are flagged, to be reported as closed.
Duplicates
The same holder with different data across reports is detected before the file goes out.
Why a CRS 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. |
Correction without CorrDocRefId | A correction has to name the record it replaces. Without that reference it is treated as a new account, and the holder ends up reported twice. |
| Jurisdiction off the list | A residence that is not on the Luxembourg list for that reporting year. The list changes, and a file built on last year’s is wrong this year. |
| TIN in the wrong shape | A tax identification number that does not match the format of the declared country of residence — separators left in, or the wrong person type. |
| New data and corrections in one file | The ACD expects them in separate files. Mixing them has both rejected. |
| 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 correction
The platform keeps the history of every record sent and accepted. You only edit the accounts; it works out what the ACD must receive.
| What you do | What is filed with the ACD |
|---|---|
| Change an account already accepted | Correction, DocTypeIndic OECD2, referencing the accepted record |
| Delete an account already accepted | Deletion, OECD3 |
| A holder moves to another reportable jurisdiction | Deletion for the old jurisdiction, new record for the new one |
| The reporting FI’s details change | Corrected reporting FI record |
| Nothing to report for a reporting FI | A nil report in the ACD format |

CRS reporting in Luxembourg — frequent questions
What is the deadline for CRS reporting in Luxembourg?
CRS 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 CRS report with the ACD?
Luxembourg reporting financial institutions under the law of 18 December 2015: investment entities such as funds, custodial and depository institutions, and specified insurance companies, unless they qualify as non-reporting financial institutions.
Which jurisdictions are reportable?
Those on the Luxembourg list of reportable jurisdictions for the reporting year. The platform applies the list of each year automatically and shows the accounts that fall outside it.
How do I correct a CRS report already accepted by the ACD?
Edit the account in the platform. It sends a correction (OECD2) or a deletion (OECD3) referencing the record the ACD accepted, in a separate corrections file.
Can I import my data from Excel?
Yes. You match the columns of a custodian’s workbook once; the profile is remembered for the next file. One workbook can hold the accounts of several reporting FIs of a client.
Does the platform also handle FATCA?
Yes. CRS and FATCA reports are prepared in the same project. See FATCA reporting in Luxembourg.
