適格請求書等保存方式（インボイス制度）に関する包括的な知識ベース。 制度の概要、記載要件、経過措置、仕入税額控除ルール、登録判断を支援する。
インボイス制度（適格請求書等保存方式）は、令和5年（2023年）10月1日に開始された消費税の仕入税額控除に関する制度。課税事業者が仕入税額控除を受けるためには、原則として「適格請求書発行事業者」が発行する「適格請求書（インボイス）」の保存が必要となる。適格請求書発行事業者になるには税務署への登録申請が必要で、登録番号（T+13桁）が付与される。
令和8年度税制改正大綱（R7.12.26閣議決定）により、3割特例の新設、経過措置スケジュールの5段階化など大幅な変更がある。
| 措置 | 内容 | 適用期限 |
|---|---|---|
| 2割特例 | 売上消費税額の20%を納付 | R8.9.30を含む課税期間まで |
| 免税事業者仕入控除 | 80%→70%→50%→30%→0% | R11.10.1で完全移行 |
| 少額特例 | 税込1万円未満はインボイス不要 | R11.9.30まで |
| 少額返還インボイス免除 | 税込1万円未満は返還インボイス不要 | 恒久措置 |
