Japan suspends e-Tax after detecting suspicious communications
Japan’s National Tax Agency suspended e-Tax on November 4 after detecting suspicious communications from outside the system.
e-Tax is the government service people use to file tax returns and make payments online.
The system is unavailable during emergency maintenance, leaving users unable to access it.
The agency said no taxpayer information leak had been confirmed at the time.
It has not said what caused the suspicious communications.
There was no estimate for when service would return, and the agency said it would post updates on the e-Tax website.
