About This App

This is the Japanese National Tax Agency (NTA) macOS application for preparing and filing annual income tax returns (確定申告書) and other tax documents. It is a government-provided tool used by Japanese taxpayers, freelancers and business owners to complete their mandatory tax filing each year. The application guides users through the tax form completion process and enables electronic submission to the NTA.

We could not find public information about whether a native Apple Silicon build of this NTA application exists. Since this is an official government tax-filing tool with a critical annual deadline, contact the National Tax Agency directly through their official support channels (keisan.nta.go.jp or the NTA help desk) to ask whether they have released or plan to release a native Apple Silicon version before macOS 28 arrives in September 2028. An Intel-only build will stop launching at that point. If a native build has not been announced, ask the NTA when they expect to ship one, as many government agencies are still completing their own Apple Silicon migration. In the meantime, the Intel version continues to run under Rosetta 2, so tax filing remains possible on current macOS releases.
