Tax reporting made easy with AIA | IDES Reporter

  • Enables organizations to deliver both AIA / EAR and FATCA tax reporting.

  • Checks XML files for AIA / EAR or FATCA conformity and provides data encryption according to the respective specifications.

  • 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.

  • Provides easy-to-use data upload and status tracking functionality.


Financial institutions in Switzerland have to collect data according to the Common Reporting Standard (CRS) or AIA / EAR.

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

FATCA Reporting

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

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

XML Digital Signature and Signature Validation compliant with the W3C XML Digital Signature Specification ( including schema validation.

AIA | IDES Reporter 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 the 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.
