IRS Form 1065 (Schedule K-3) – In the complex world of U.S. taxation, partnerships with international dealings must navigate specific reporting requirements to ensure compliance. IRS Form 1065 Schedule K-3, titled “Partner’s Share of Income, Deductions, Credits, etc. – International,” plays a crucial role in this process. This form helps partners report their share of international tax items accurately on their individual or corporate tax returns. Whether you’re a partnership preparing the form or a partner receiving it, understanding Schedule K-3 is essential for avoiding penalties and optimizing tax positions.
This article provides a comprehensive overview of Schedule K-3, including its purpose, key sections, filing requirements, and recent updates. We’ll draw from official IRS guidance to ensure accuracy and relevance for tax year 2025 and beyond.
What Is IRS Form 1065 Schedule K-3?
Schedule K-3 is an extension of Schedule K-1 from Form 1065, the U.S. Return of Partnership Income. It specifically focuses on international tax matters, reporting a partner’s distributive share of items like foreign income, deductions, credits, and other global transactions. Partnerships use this form to provide detailed information that partners need for forms such as Form 1116 (Foreign Tax Credit for individuals) or Form 1118 (Foreign Tax Credit for corporations).
Introduced for tax year 2021, Schedule K-3 ensures transparency in international tax reporting, helping partners calculate items like foreign tax credits, deductions for foreign-derived intangible income (FDII), subpart F inclusions, and base erosion and anti-abuse tax (BEAT) liabilities. It’s particularly relevant for partnerships with foreign activities, assets, or partners who may claim credits or deductions related to international operations.

Purpose of Schedule K-3
The primary goal of Schedule K-3 is to report items of international tax relevance from a partnership’s operations. This includes details on foreign source income, expenses, taxes paid or accrued abroad, and other data that affect a partner’s U.S. tax liability.
Partners use this information to:
- Compute foreign tax credits to avoid double taxation.
- Determine inclusions under sections 951(a) and 951A (related to controlled foreign corporations, or CFCs).
- Calculate FDII deductions under section 250.
- Assess BEAT under section 59A.
- Report on passive foreign investment companies (PFICs) and other international entities.
Even partnerships with limited or no foreign activity may need to prepare Schedule K-3 if partners require the data for their returns, such as claiming foreign tax credits or handling base erosion payments. All amounts are typically reported in U.S. dollars, with exceptions noted where functional currency applies.
Who Must Prepare and Receive Schedule K-3?
Who Prepares It?
Partnerships (including domestic ones) must prepare Schedule K-3 if they have international tax items or if partners need the information for their returns. This includes partnerships with:
- Foreign source income or assets.
- Foreign taxes paid or accrued.
- Interests in foreign corporations, PFICs, or other entities.
- Partners who are foreign or who may claim foreign tax credits.
Exceptions apply, such as the domestic filing exception for partnerships with no foreign activity and partners who don’t request the form by a specified deadline (one month before the partnership’s return due date). Partnerships must also prepare it upon request from eligible partners.
Who Receives It?
Partners receive Schedule K-3, including:
- U.S. individuals, corporations, estates, trusts.
- Foreign partners for reporting effectively connected income (ECI) or fixed, determinable, annual, or periodical (FDAP) income.
- Pass-through entities (like other partnerships) that use it to prepare their own Schedules K-3.
If a partner is a domestic corporation, they might receive it to determine BEAT or FDII.
