The announcement informs the public that, due to scheduled technical upgrades, the “MojDDV” system will be temporarily unavailable on June 23, 2026, beginning at 12:00 noon. The suspension is part of a planned infrastructure enhancement aimed at improving system stability, security, and performance for future tax-related services. During the downtime, users will be unable to access the online tax filing portal, submit declarations, or retrieve personal tax data through this platform. The administration advises all taxpayers and businesses to complete any urgent submissions or payments before the shutdown and to plan any necessary filings for alternative channels, such as in‑person visits to local tax offices or the use of authorized third‑party service providers. A notice posted on the agency’s website explains that the upgrade work will involve server maintenance, database optimization, and the implementation of new security protocols. Once the works are finished, the system is expected to resume normal operations, with enhanced features designed to streamline user experience and reduce processing times. The announcement also provides a contact hotline and email address for inquiries regarding the interruption, as well as information on how to obtain copy of previously filed documents during the outage. Stakeholders are encouraged to monitor official communications for updates on the expected restoration time and to follow recommended contingency measures to avoid disruptions in their tax obligations.
