Japan National Tax Agency issues fraud warnings and tax compliance advice

The National Tax Agency of Japan has issued a warning regarding fraudulent emails and communications impersonating the agency or the e-Tax system. These scams often use urgent subject lines such as “Urgent,” “Confirmation,” or “Warning” to trick individuals into clicking links, downloading apps, or opening attachments under the guise of tax refunds, unpaid taxes, or password changes. The agency clarified that it never sends emails to guide refund procedures, request payments, or prompt app downloads.

In a separate context, former tax officials have provided insights into tax compliance and investigation methods. Expert commentary highlights common mistakes made by employees filing tax returns due to side businesses, as well as the specific investigative techniques used by tax authorities to detect tax evasion in various sectors, including nightlife and entertainment industries.
