The eCDF platform
Last update
You are required to file financial data with the State on a regular basis.
The platform for electronic gathering of financial data (eCDF) can be used to:
- prepare your data; and
- validate your data electronically; and
- file your data with the State online.
The eCDF platform is accessible at www.ecdf.lu.
The eCDF platform can be used for all types of interim and annual returns, such as:
All VAT returns and recapitulative statements for goods and services must be filed electronically using the eCDF platform.
When creating an eCDF account, you, the applicant (whether you are a natural or legal person), will have to:
- select the type of eCDF account you wish to open. The type of account you choose will depend on the features you require (filings for yourself or for other companies);
- specify a primary user, i.e. the account administrator, who has control over the entire eCDF account. The account administrator must possess a digital certificate that is compatible with the type of eCDF account that is being applied for.
You can only have one account.
Who is concerned
Entities concerned
Any natural person (self-employed) or legal person subject to VAT who is required to:
- submit electronically:
- their VAT returns; and
- their recapitulative statements for goods and services; or
- prepare annual financial statements.
eCDF account holder
You can apply to be the holder of an eCDF account:
- if you are a legal or natural person, for:
- a professional LuxTrust certificate; and
- an eIDAS certificate;
- for a private LuxTrust certificate, only if you are a natural person.
The account administrator
On the eCDF account application form, you must specify the account administrator.
That person must be the user with the LuxTrust/eIDAS certificate.
The eCDF account users
The eCDF account administrator can:
- grant one or more of their business's employees access to the eCDF account; and
- manage users directly through their account, without having to file another application for access with the eCDF administration.
Each eCDF account user / account administrator must possess:
- a professional LuxTrust certificate containing exactly the same Organisational Unit (OU) identification number, if the eCDF account is for a professional LuxTrust certificate with verification of the 'OU'. Users cannot be added if they have a different 'OU' identification number; or
- a private LuxTrust certificate or an eIDAS certificate, if it is a private LuxTrust or eIDAS account.
How to proceed
Types of eCDF accounts
Professional LuxTrust eCDF accounts with verification of the 'Organisational Unit' (OU)
Types of certificates
Both natural and legal persons can apply to open an eCDF account using a professional LuxTrust certificate, which enables authentication using:
- a LuxTrust Smartcard Pro (professional smartcard); or
- the LuxTrust Mobile Pro application; or
- LuxTrust Pro Scan.
Features
With this type of account, filings can be made for:
- yourself, as the eCDF account holder;
- other companies.
This type of account is also intended for accounting firms as it can be used to file returns for their clients.
Means of authentication
The means of authentication must satisfy the following criteria:
- the means of authentication must be a professional LuxTrust certificate;
- for security purposes, the means of authentication must contain the business's 'Organisational Unit' (OU) identification number (if it has one). This number must be one of the account holder's official Luxembourg identification numbers, i.e.:
- their Luxembourg VAT number;
- their RCSL number, i.e. their number in the Luxembourg Trade and Companies Register (Registre de commerce et des sociétés luxembourgeois – RCSL);
- their 13-digit Luxembourg national identification number (Matricule);
- all professional LuxTrust certificates that are subsequently attached to the eCDF account must contain exactly the same 'OU' identification number as the one in the account administrator's (i.e. the primary user's) professional LuxTrust certificate.
This identification number must be specified when signing up for a LuxTrust product. It is up to the business to decide which of the above identification number it wishes to use as its OU identification number. All users of the same account must have the same 'OU'.
If a LuxTrust professional certificate is already in use in the company, it is recommended to align with the 'OU ' of this certificate.
If no LuxTrust professional certificate is in use within the company and it has an RCSL number, it is recommended that the RCSL number be used.
In practice:
- The primary eCDF account user – i.e. the eCDF account administrator – must record the eCDF account's 'OU' identification number in their certificate; and
- all other users must specify the same OU identification number when ordering a LuxTrust product; otherwise, they cannot be attached to the eCDF account.
If need be, the holder of a professional LuxTrust certificate can find the 'OU' identification number recorded in their certificate by using the 'Test my certificate' tool on the LuxTrust website.
Applicants that do not have a Luxembourg identification number – such as foreign accounting firms – but want to file returns on behalf of their customers should contact the eCDF Helpdesk. It is not necessary to undertake any procedure to obtain a 13-digit Luxembourg national identification number (Matricule).
eCDF accounts for private LuxTrust certificates
Types of certificates
Natural persons can apply to open an eCDF account for a private LuxTrust certificate, which enables authentication using:
- a LuxTrust private smartcard; or
- the private LuxTrust mobile application; or
- the private LuxTrust Scan device.
You can also use your Luxembourg eID (electronic identity card).
Features
With this type of account, filings can only be made for the account holder, i.e. yourself.
Means of authentication
You can authenticate your identity using your private LuxTrust certificate.
You are both the eCDF account holder and the eCDF account administrator.
eCDF accounts for eIDAS certificates
Types of certificates
Both natural and legal persons can apply to open an eCDF account with an eIDAS certificate.
Features
With this type of account, filings can only be made for the account holder, i.e. yourself.
It does not allow filing on behalf of other companies and is not suitable for accounting firms.
Means of authentication
Your eIDAS certificate will be used to authenticate your identity.
A natural person with an eCDF account in their own name can only register an eIDAS certificate in their own name on said eCDF account.
