2025 Schedule OI (Form 1040‑NR) – Fillable Spanish PDF

This schedule collects additional details about income, treaty benefits, and other tax‑related information that the main 1040‑NR does not capture. It is mandatory for most non‑resident alien returns and must be attached to the completed Form 1040‑NR.
