e-Tax Japan review
A free, official filing route for Japanese individuals who need broad e-Tax coverage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
e-Tax Japan is the National Tax Agency of Japan's online system for individual tax filing, applications, notices and payments. It is aimed at Japanese filers who need to prepare and transmit income-tax, consumption-tax or gift-tax returns electronically. The service also supports tax applications and notifications, payment procedures, filing-result messages, tax-office notices, certificates and electronic submission of supporting-document image data. It fits solo and small users who want an official route rather than a general-purpose tax workflow.
The service is free to use and covers a broad set of filing tasks without a paid tier structure. Users can work through browser-based e-Tax software without local installation, use downloadable desktop software for filing data and attachments, or access the service from computers and smartphones. My Number Card and My Number Portal authentication are supported, along with electronic signatures for transmitted filing data. Payment options include direct debit, internet banking and Pay-easy. Connectivity, electronic certificates, card readers and banking fees may add costs outside the service itself.
Its strongest advantage is official filing breadth: users can move from return preparation to transmission, payment and message-box access within the same system. The trade-off is a focused ecosystem. My Number Portal is the named integration, while the Android e-Tax app has been discontinued and smartphone access now runs through the web service and required authentication apps. Filers who need official electronic submission and a wide range of Japanese tax procedures should choose e-Tax Japan. Those seeking a broader network of third-party integrations or a more guided tax-preparation experience may prefer another product.
