Schedule K‑3 (Form 1120‑S) is the IRS’s dedicated worksheet for reporting a corporation’s international tax items that flow through to each shareholder’s Schedule K‑1. If your S corporation has foreign income, taxes paid, or other cross‑border activities, you must complete this form.
Schedule K‑3 expands on Schedule K‑2 to capture detailed foreign tax credit limitations, foreign source income, and other international items. All S corporations that report foreign activities on their Form 1120‑S must file Schedule K‑3, and shareholders use the information to claim foreign tax credits on their personal returns.
