eCDF Luxembourg: file your returns and accounts.
eCDF is the Luxembourg State's electronic platform to submit tax returns (VAT, taxes) and the structured data of annual accounts. Here is what it is for, who must use it and how to file, or delegate.
eCDF (electronic collection and filing of financial data) is the Luxembourg State platform, under the Registration Duties, Estates and VAT Authority (AED), for the electronic collection and filing of tax returns and structured financial data (balance sheet, profit-and-loss account under the standard chart of accounts).
What is eCDF in Luxembourg?
eCDF is the State platform for the electronic filing of financial data. It is used by companies and their fiduciaries to submit, in a dematerialised and structured form, their tax returns and the elements of their annual accounts.
The aim is standardisation: normalised forms (under the standard chart of accounts, PCN) ensure data that is comparable and usable by the authorities.
What can be filed via eCDF?
Mainly: VAT returns (monthly, quarterly, annual), certain tax returns, and the structured forms of the annual accounts (balance sheet and profit-and-loss account) used for the legal filing.
The legal filing of annual accounts is done with the Trade and Companies Register (RCS / Luxembourg Business Registers); eCDF provides the accompanying structured financial-data forms.
How to file your annual accounts and VAT?
In practice: prepare the accounts in LuxGAAP, fill the structured forms (PCN), pass the consistency checks, then submit via eCDF (and, for annual accounts, file with the RCS). VAT returns follow the same electronic capture-and-submit principle.
A fiduciary automates this chain: preparation, checks, submission and tracking of receipts, to avoid errors and delays.
Access: LuxTrust authentication
Access to eCDF requires strong authentication via a State authentication product (a LuxTrust certificate, for example). Filing via eCDF is free; publication fees may apply separately for filing with the RCS.
If you entrust us with your accounting, we file on your behalf, fully compliant.
Deadlines and common errors
For annual accounts: approval by the general meeting within 6 months of year-end, then filing within one month, i.e. 7 months after closing. For VAT: depending on periodicity (monthly, quarterly, annual). Missing deadlines triggers penalties.
Common errors: forms inconsistent with the trial balance, missing PCN items, late filing, wrong financial year. We secure everything upstream for a rejection-free filing.
