This skill should be used when the user needs to calculate their income tax (所得税), compute deductions, or import withholding slips. Trigger phrases include: "所得税を計算", "確定申告書を作成", "控除を計算", "源泉徴収票を取り込む", "所得税額", "納付額を計算", "還付額を計算", "第一表", "第二表", "申告書B", "所得控除", "税額控除".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 所得税計算（Income Tax Calculation） 事業所得・各種控除から所得税額を計算するスキル。 settlement スキルで決算書の作成が完了していることを前提とする。 計算結果は `/e-tax` スキル（Claude in Chrome）で確定申告書等作成コーナーに入力する。 ## 設定の読み込み（最初に実行） 1. `shinkoku.config.yaml` を Read ツールで読み込む 2. ファイルが存在しない場合は `/setup` スキルの実行を案内して終了する 3. 設定値を把握し、相対パスは CWD を基準に絶対パスに変換する: - `db_path`: CLI スクリプトの `--db-path` 引数に使用 - `output_dir`: 進捗ファイル等の出力先ベースディレクトリ - 各ディレクトリ: ファイル参照時に使用 ### パス解決の例 config の `db_path` が `./shinkoku.db` で CWD が `/home/user/tax-2025/` の場合: - `shinkoku tax calc-income --input /home/user/tax-2025/output/income_input.json` ## 進捗情報の読み込み 設定の読み込み後、引継書ファイルを読み込んで前ステップの結果を把握する。 1. `.shinkoku/progress/progress-summary.md` を Read ツールで読み込む（存在する場合） 2. 以下の引継書を Read ツールで読み込む（存在する場合）: - `.shinkoku/progress/06-settlement.md` - `.shinkoku/progress/02-assess.md` - `.shinkoku/progress/05-furusato.md` 3. 読み込んだ情報を以降のステップで活用する（ユーザーへの再質問を避ける） 4. ファイルが存在しない場合はスキップし、ユーザーに必要情報を直接確認する ## 基本方針 - settlement スキルで青色申告決算書が完成しているか確認してから開始する - 所得の計算 → 控除の計算 → 税額の計算 の順序で進める - 各ステップの計算結果をユーザーに提示し、確認を得る - references/form-b-fields.md の各欄に正しく値を設定する - 端数処理ルールを厳守する: - 課税所得: 1,000円未満切捨て（国税通則法118条） - 復興特別所得税: 1円未満切捨て（復興財源確保法13条） - ㊺ 所得税及び復興特別所得税の額: 端数処理なし …

How to install
mdr add kazukinagata/shinkoku/income-tax@sha256:21621328c3d2c1a3The line at the top of this page pins the label git:20260909.675d496, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
