The Federal Tax Service Migrates Tax Infrastructure to a Russian Database Platform
Key components of the automated information system “Nalog-3,” which supports the Federal Tax Service (FTS), have been migrated to a Russian-developed database management system.
The FTS completed the project in collaboration with the Main Research, Innovation and Implementation Center (GNIVTs). Nine mission-critical subsystems of the Nalog-3 automated information system now run on Postgres Pro Enterprise Certified, an industrial-grade database management system designed for high-load environments and developed by Russian company Postgres Professional.
The Scale of the Migration
The project took four years to complete. Oracle Exadata, a hardware and software platform, previously served as the digital platform’s core, and some Nalog-3 subsystems still run on it. However, the accounting and compliance subsystems, which contain critical information totaling more than 2 petabytes, have been migrated to Russian software. That represents about 45% of all data in the information system. It is one of the largest transitions to Russian database technology ever undertaken by the public sector.
Nalog-3 processes data on millions of taxpayers, administers tax collections, and exchanges information with other government services. Migrating part of the system to Postgres Pro Enterprise Certified required the team to build a new technology layer within the existing infrastructure. The GNIVTs’s team ensured compatibility with application components, preserved data throughout the migration, kept mission-critical processes running without interruption, and maintained the required performance. The project also reduced the risk of losing critical data by distributing workloads across multiple fault-tolerant clusters.
Using Russian software in areas once dominated by foreign platforms demonstrates the maturity of Russia’s IT industry and reduces the technological dependence of a high-load government system that forms part of the country’s critical infrastructure.
Demand for Import Substitution
Russia is gradually replacing foreign software in government information systems and corporate IT environments. The FTS project’s successful completion could help accelerate that shift.
“We started by populating individual databases with a few terabytes of data. Now, after completing the full implementation cycle, we have databases holding up to 60 TB, with several terabytes added every month, and the system is handling that load. This project has confirmed that Postgres Pro Enterprise Certified can support applications at the federal level,” said Sergey Shturmin, deputy director general of GNIVTs.
Russian IT products are doing more than keeping high-load systems running: they are also improving performance. Meanwhile, systems integrators have developed the expertise needed to move organizations from foreign platforms to Russian alternatives without disrupting operations. Demand for these migrations is expected to grow over the next few years. The FTS itself still has components that need to be moved to a Russian database management system.
Moving Toward Technological Independence
Russian government agencies and businesses have been moving from foreign database management systems to domestic alternatives for years. Goznak, for example, began a phased migration of electronic document management systems at the St. Petersburg Mint and other divisions to Postgres Pro in 2019.
One of the largest migrations has been undertaken by the state corporation Rosatom. Since 2020, it has been moving its automated financial management systems, electronic document management systems, and corporate data warehouse to Russian platforms. This has helped secure technological independence for hundreds of enterprises across Russia’s nuclear industry.
In 2025, the Federal Treasury completed the migration of the State Information System for State and Municipal Payments from Oracle to Postgres Pro Shardman, a distributed database management system. Transferring the 240 TB database took more than two years and was completed without interrupting mission-critical services. The system’s performance and fault tolerance also improved.
A Foundation for Further Deployments
Experience gained from these projects confirms that Russian database management systems can support high-load federal and corporate systems processing hundreds of terabytes of data. Migrations are increasingly delivering more than just preserved functionality: they are also bringing substantial performance gains, as demonstrated by Rosatom’s experience and the Federal Treasury project.
Each successful project reduces the risks associated with the next one and builds confidence in Russian solutions. In Russia, database import substitution is no longer simply a forced measure; it is becoming an economically justified way to modernize critical infrastructure. Over the next three to four years, this shift is expected to affect major corporations’ financial systems, government agencies’ databases, corporate data warehouses, and document management systems. The experience gained is also expected to strengthen the competitive position of Russian systems integrators and database developers in global markets.
