Tax reporting made easy with AIA | IDES Reporter

AIA | IDES Reporter is a software tool that enables organizations to deliver both AIA / EAR and FATCA tax reporting. Our product checks XML files for AIA / EAR or FATCA conformity and provides data encryption according to the respective specifications. Furthermore, it provides easy-to-use data upload and status tracking functionality. AIA / EAR and FATCA modules can be licensed separately. Users who have to report according to both standards, AIA / EAR and FATCA, will be able to use one single tool with the same process for both purposes.


Automatischer Informationsaustausch / Echange automatique de renseignements


Financial institutions (FI) in Switzerland have to collect data according to the Common Reporting Standard (CRS) or AIA / EAR (Automatischer Informationsaustausch / Echange automatique de renseignements).

Before uploading to ESTV, XML files have to be encrypted with cryptographic mechanisms similar to US FATCA reporting.

FATCA Reporting

Foreign Account Tax Compliance Act


Financial Institutions (FI) that have signed a Foreign Account Tax Compliance Act (FATCA) agreement with the U.S. Internal Revenue Service (IRS) have to transfer relevant business data to IRS’ International Data Exchange Service (IDES).

This data transfer has to comply with strict specifications, including cryptographic requirements.

AIA | IDES Reporter ensures that your XML data is correctly signed, encrypted and packed for transmission; all steps executed are logged for control and audit purposes.

AIA | IDES Reporter can handle one or multiple ESTV/FTA ID’s or Global Intermediary Identification Numbers (GIINs).

AIA | IDES Reporter produces XML Digital Signature and Signature Validation according to the W3C XML Digital Signature Specification ( including schema validation. It takes care of compressing the digitally signed data file, encrypting it, including certificate chain validation via OCSP or CRL, and naming it as required by ESTV/FTA or IDES standards. Thus, it produces the sender metadata file and the ESTV/FTA or FATCA data packet for you.

After successful upload, the sender receives a notification message from ESTV/FTA or IRS. For IRS messages, AIA | IDES Reporter validates this notification message using the same cryptographic mechanisms, thus guaranteeing your FATCA file validity and confirming the success of your FATCA tax reporting process.

Among others, AIA | IDES Reporter security features include the production of RSA signatures employing any hash function from the SHA family, support for RSA keys in PKCS#12 file format, AES cipher, secure memory locked vectors and secure memory wipe out after usage.

In order to use AIA | IDES Reporter successfully, your banking solution must be able to produce AIA / EAR data according to ESTV/FTA specifications or FATCA data according to FATCA specifications. In addition you have to be fully enrolled in the ESTV/FTA SuisseTax and / or IRS IDES system.
