Quick Facts

The partnership (or its authorized representative) files Schedule K‑2.
It captures foreign‑source income, foreign taxes paid or accrued, foreign tax credits, and other international items that flow through to partners.
Schedule K‑2 is due the same day as Form 1065 – generally March 15 for calendar‑year partnerships, with extensions available to September 15.
Attach Schedule K‑2 to the paper Form 1065 when mailing to the IRS Service Center, or upload it as part of the electronic filing package through approved software.
Errors can cause mismatched partner statements, trigger IRS notices, and delay partner K‑1 processing, potentially leading to penalties.
1. Gather all foreign income, expense, and tax data for the partnership year. 2. Complete Part I (income) and Part II (taxes and credits) of Schedule K‑2 using the partnership’s books. 3. Transfer the totals to each partner’s Schedule K‑1 (Box 16). 4. Review totals for consistency with Form 1065 lines 1‑10. 5. Attach Schedule K‑2 to the final Form 1065 before filing.
