The National Tax Agency of Japan's new system KSK2 officially launches: AI enhances cryptocurrency declaration verification

According to CoinPost, the National Tax Agency of Japan officially launched the first upgrade of its next-generation core system KSK2 on September 24, marking the first upgrade in about 25 years. The new system centers around personal identification numbers (My Number) and corporate identification numbers, achieving unified management of individual and corporate data, and introducing AI technology to enhance the detection of improper declarations.

Cryptocurrency traders and investors are particularly affected, as annual transaction reports submitted by exchanges, bank account deposit and withdrawal records, and information exchange with overseas tax authorities (CRS) data have all been included in the key analysis scope of AI.

In addition, statements related to "cryptocurrency profits" on social media will also be compared with declaration data, significantly increasing the risk of tax investigations. The National Tax Agency has also integrated horizontal data between corporations and individuals, making it easier to identify inconsistencies in assets and income for investors who purchase cryptocurrencies through private company investments or with funds from gifts and inheritances.

Industry insiders emphasize that properly retaining annual transaction reports and accurately and completely declaring them has become an urgent priority.
