Regulatory reporting notes for investment funds and financial companies in Luxembourg and across the EU. What changed, what it means for the data you file, and what breaks a submission in practice.
We publish here as the rules move: CSSF and BCL circulars, EBA and ESMA frameworks, DORA, AIFMD, CESOP, FATCA and CRS. Each note is written from the filing side — the fields that change, the validations that start failing, and the dates that matter — rather than as a summary of the text. If you are looking for a tool instead, the DORA register validator, the VAT checker and the LEI lookup are free and need no account.
