Schedule K-3
Schedule K-3 is the partner-level or shareholder-level companion to Schedule K-2, reporting each individual partner's or shareholder's allocated share of international tax items from a partnership (Form 1065) or S-Corporation (Form 1120-S). While K-2 reports entity-level international tax information in aggregate, K-3 breaks down each partner's or shareholder's proportionate share of foreign tax credits by category and country, foreign-source income by basket (general, passive, branch), treaty benefits, GILTI inclusions, Section 250 FDII deductions, and PFIC reporting. Each K-3 must be provided to the relevant partner or shareholder by the partnership's or S-Corp's filing deadline — March 15, or September 15 if extended. The K-3 replaced the prior practice of providing international tax information via ad hoc statements, creating a standardized but significantly more complex reporting framework. A 50-page K-3 is not unusual for entities with operations spanning multiple countries. Individual partners use K-3 information to complete Form 1116 (Foreign Tax Credit), Form 8992 (GILTI), and other international tax forms on their personal returns. The compliance burden is particularly heavy for venture-backed startups that raise capital from foreign investors: even a single non-resident alien LP in a fund structure triggers K-3 filing requirements for the entire entity. For multi-member LLCs with international members, the cost of K-2/K-3 preparation adds $1,500–$5,000 per entity to annual tax preparation fees. doola handles K-3 preparation and distribution as part of its comprehensive tax filing services for LLCs with foreign members, ensuring each partner receives the international tax information needed for accurate individual return filing.
