（No.2）確定申告書等作成コーナーAP
This app is the official desktop application for Japan's National Tax Agency (NTA) used to prepare and file tax returns (確定申告), withholding tax forms, and other statutory tax documents required by Japanese tax law. It serves individual taxpayers, small business owners, and accountants who must submit annual income tax filings to the Japanese tax authority. The app guides users through a structured form-filling process, performs calculations, and generates files ready for submission to the NTA or printing. It is essential for anyone in Japan with income reporting obligations.
AI Recommendation
1 suggestionNo search results are available to confirm whether this official Japanese tax-filing app has a native Apple Silicon build. Given that it is a government utility maintained by Japan's National Tax Agency (NTA), contact the NTA directly through their website at nta.go.jp to ask whether a native build is available or planned. As of today, May 2026, you have roughly 27 months before macOS 28 arrives in September 2028 and Intel-only apps stop working, but an official government app like this is unlikely to receive urgent updates once Rosetta 2 is removed. If the NTA indicates no native version is planned, you should begin preparing an alternative workflow — for example, using the web-based filing system at e-tax.nta.go.jp if available, or consulting with a Japanese accountant about compliant filing alternatives. Contact the developer as soon as possible to confirm their support roadmap.
