The IBA–developed electronic system to exchange information between the tax bodies of Belarus and the Russian Federation (ES VAT) was implemented by the Ministry of Taxes and Duties of the Republic of Belarus. This system designed to automate the processing of the paid indirect taxes is a secure multilevel intranet accessible to tax divisions of the two states.

The system provides the following basic features:

• Multilevel structure: Four levels were created in the system: taxpayer, province, region, and Central administration.
• Distribution: The data are distributed between several database servers and data integration is implemented using replication mechanism.
• Web–driven application: The functionality of automated workstations is provided through web–browser.
• Multiplatform: In addition to PCs, IBM xSeries 206 and 236 servers with Windows and Linux operating systems are used.

• Security: Information protection tools certified by the Belarusian State Center for Information Security ensure the system's security. Special components of the system detect intrusions, prevent unauthorized access, and provide cryptographic protection and the use of electronic digital signature (EDS).

According to the Belarusian weekly Computer News, "the system's creation served as the completing stage of the new taxation mechanism".
