According to CoinMeta, the Japanese National Tax Agency officially launched a new generation of core tax system on September 24th, integrating data and applications that were previously managed separately for different tax categories in order to enhance tax information analysis and declaration verification. Citing tax agency materials, annual transaction reports provided by cryptocurrency exchanges, bank fund records, and overseas tax information exchange data can be used to identify potential omissions in cryptocurrency transaction declarations. The Japanese National Tax Agency officially confirmed that the system update was completed on September 24th, but this announcement did not disclose the specific analysis rules for cryptocurrencies.
