令和７年分 年末調整控除申告書作成用ソフトウェア
This is the official year-end tax adjustment certificate creation software from Japan's National Tax Agency (Kokuzei-Cho), designed for the 2025 tax year (Reiwa 7). The app helps Japanese employees generate and file year-end tax adjustment documents (nenchouyoku) and deduction claim forms with their employers, a mandatory annual process in Japan. It guides users through calculating eligible deductions, personal exemptions, and adjustments based on their income, marital status, dependents and life circumstances, then produces the forms required by Japanese tax law. The app is provided free by the government and is updated annually to reflect changes in tax rules and form requirements for each fiscal year.
AI Recommendation
1 suggestionWe could not find public information about whether a native Apple Silicon build of this software exists. The National Tax Agency's official tax software is typically released as annual editions with specific fiscal-year validity (this version is for the 2025 tax year, or Reiwa 7). Contact the National Tax Agency's technical support or check their official website directly to ask whether a native Apple Silicon build is available, or whether this Intel-only version will be updated before macOS 28 ships in September 2028. If the agency does not release a native version, this app will stop launching when Apple removes Rosetta 2, which could leave you unable to file required tax documents in late 2028 and beyond. For future tax years, verify native support at time of download so you do not encounter this situation again.
