Filing notes for 2026: The IRS requires all partnerships to maintain documentation supporting their Schedule B responses, especially regarding audit elections under section 6221(a) and ownership of foreign entities. Partnerships that elect out of the centralized partnership audit regime must attach a valid election statement and provide partner details. Always reconcile these disclosures with entries on Schedules K, L, and M-1.

Schedule B ensures compliance with various reporting requirements that extend beyond basic income or deduction reporting. The form identifies whether a partnership has foreign or tax-exempt partners, owns interests in other entities, or must file additional international information returns. It also captures critical elections like the section 754 basis adjustment. Completing this section accurately minimizes IRS correspondence and improves the accuracy of partner K-1 statements.
For official guidance, refer to the IRS Instructions for Form 1065 and verify that your responses align with federal partnership reporting standards.
