Background context for invoice-system input tax credit rules (仕入税額控除) in the shinkoku tax filing plugin. Contains eligibility requirements, the 6 permanent exceptions (帳簿のみ保存の恒久特例), transitional measures for purchases from tax-exempt businesses, and storage requirements. This skill is not user-invocable — Claude loads it automatically when responding to input tax credit questions under the invoice system.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'tax-invoice-credit-context' ] || [ -L ~/.agents/skills/'tax-invoice-credit-context' ]; then echo 'A skill folder named tax-invoice-credit-context already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/kazukinagata/shinkoku' "$d" && git -C "$d" checkout --quiet '607574d5e5ce63898b2560e083a555d074ef258d' -- 'skills/tax-invoice-credit-context' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/tax-invoice-credit-context' ~/.agents/skills/'tax-invoice-credit-context' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'tax-invoice-credit-context' ~/.claude/skills/'tax-invoice-credit-context' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
