e-Tax Japan

What e-Tax Japan does

Through e-Tax, users can file returns, pay taxes, submit statutory records, and complete tax applications and notifications online. Individuals can create and submit income, consumption and gift tax returns using the National Tax Agency’s return-preparation site.

Support covers self-employment, investment income and rental income. My Number Portal may bring eligible salary and pension withholding details and deduction certificates into a return, although some information requires setup beforehand or employer submission.

Fees and plans

The e-Tax plan has no charge. Tax-office procedures also carry no fee, and there is no trial period because the plan is already free.

Users may still pay for internet service, certificates, a card reader or bank services.

Where it runs

The Web version works on Windows and macOS computers, smartphones and tablets without requiring the desktop program. Its recommended computer environments list Windows 11 and macOS 13, 14, 15 and 26 with specified browsers.

For mobile use, the listed recommendations are Android 13–16 with Chrome and specified iOS and iPadOS versions with Safari. Some Web functions do not work on smartphones, and the return-preparation site cannot process certain individual return content.

Windows and macOS users can download e-Tax software. That program creates tax filings and can create and submit specified supporting forms with them.

Protection, as e-Tax publishes it

Personal information is encrypted while moving between users and e-Tax. The service also describes firewalls and access monitoring for its databases and servers, together with electronic signatures and certificates.

Sign-in is available through My Number Portal using a My Number Card or smartphone electronic certificate, or through a user identification number and password. The message box provides transmission results, tax-office messages and notices.

A Web response feature has allowed online replies to tax-office inquiries since September 2026.

Strengths

Tax-office procedures do not incur an e-Tax service fee. One online system handles returns, payments, applications, notifications and statutory records.

Several individual return types are supported, and after the necessary setup My Number Portal can automatically enter eligible salary, pension and deduction information. Payment can be made by direct debit, internet banking or Pay-easy ATM.

The browser option avoids a desktop installation, while the downloadable software can produce supporting forms.

Catches to check

Certain individual tax-return material is beyond the return-preparation site’s capabilities. Smartphone users also have fewer functions because some Web features are unavailable there.

Operating-system, browser and mobile-version requirements are specific. Separate spending may include internet service, certificates, a card reader and bank fees.

Imported salary, pension or deduction information may depend on prior setup or employer submission. The help desk assists with starting and running the service and with supported devices; local tax offices provide tax advice.

Who should skip e-Tax Japan

People whose individual return contains material outside the preparation site, or who need the full Web feature set on a smartphone, may need another option. Readers comparing filing products can review tax filing software.

Verdict

e-Tax Japan fits users managing Japanese tax-office procedures who want a free online way to handle returns, payments, applications and notices. Computer and mobile browser access is paired with desktop software, and eligible information from My Number Portal can reduce typing.

It is a weaker fit when a return includes unsupported material, smartphone use requires every Web function, or the listed device and browser versions are unavailable. Allow for possible internet, certificate, card-reader and bank charges.
