What e-Tax Japan is
e-Tax Japan is an online service for handling tax procedures with Japan’s National Tax Agency. Users can file and pay taxes, submit statutory records, and complete tax applications and notifications. Individuals can prepare and submit income, consumption, and gift tax returns through the National Tax Agency’s return preparation site. Downloadable desktop software creates tax filings and specified supporting forms, while browser-based software works on computers, smartphones, and tablets without installing the desktop software. Payments can be made by direct debit through e-Tax, internet banking, or Pay-easy ATMs. My Number Portal can retrieve eligible salary and pension withholding information and deduction certificates for automatic entry, though some data requires prior setup or employer submission. Users can sign in through My Number Portal with a My Number Card or smartphone electronic certificate, or with a user ID and password. The service is free, though related costs may include internet service, certificates or a card reader, and bank fees. Some individual return content is not handled by the preparation site, and some web features are unavailable on smartphones.
