What are the FEOC requirements for 45X tax credits?

Section 45X (Advanced Manufacturing) has the most comprehensive FEOC restrictions. Three core requirements apply: (A) Ownership Prohibition: cannot claim 45X if classified as a PFE, effective for tax years after July 4, 2025. (B) Material Assistance Restrictions: manufacturers cannot receive assistance from PFEs, with component-specific MACR thresholds that escalate annually (e.g., Battery: 60% in 2026, 65% in 2027, 70% in 2028, 80% in 2029, 85% in 2030+). (C) Effective Control Prohibition: no credit for components produced through effective control by an SFE.

How do I determine if a supplier is a Foreign Entity of Concern?

Use a two-step analysis. Step 1: Determine if the supplier is a Specified Foreign Entity (SFE): entities that are governments of China, Russia, North Korea, or Iran, incorporated in covered nations, owned/controlled by covered governments (>50%), or on U.S. restricted lists (OFAC SDN, Commerce Entity List, UFLPA). Step 2: Determine if the supplier is a Foreign-Influenced Entity (FIE): triggered if an SFE can appoint board members, a single SFE owns ≥25% of stock/voting rights, multiple SFEs collectively own ≥40%, SFEs hold ≥15% of outstanding debt, or entity allocates >10% of non-goods payments to a single SFE.

What is the Material Assistance Cost Ratio (MACR)?

MACR measures how much of your project comes from PFE sources. For Qualified Facilities (45Y/48E): MACR = (Total Direct Costs - PFE Costs) ÷ Total Direct Costs. For Eligible Components (45X): MACR = (Total Direct Material Costs - PFE Material Costs) ÷ Total Direct Material Costs. Example for Battery Manufacturing (2026): threshold is 60%. If total costs are $1M and PFE costs are $350K, MACR = 65%, which is compliant. The IRS must issue safe harbor tables by December 31, 2026.

What documentation do I need for FEOC compliance?

Supplier certifications must include the supplier's EIN or foreign government ID number, be signed under penalties of perjury, and state that property was not produced by a PFE. Certifications must be retained by both supplier and taxpayer for ≥6 years. Documentation needed includes: shareholder agreements and board appointment rights for ownership/FIE status; supply chain audit trails and cost allocation worksheets for MACR; technology licensing agreements for effective control analysis; and physical work test documentation for beginning of construction.

How do the new PFE rules differ from FEOC rules?

They are the same framework with different terminology. FEOC (Foreign Entity of Concern) is the umbrella term referring to the overall regulatory framework. PFE (Prohibited Foreign Entity) is the specific legal status that triggers credit disqualification, defined in OBBBA Section 7701(a)(51). PFE has two categories: Specified Foreign Entity (SFE) for direct connections to covered nations, and Foreign-Influenced Entity (FIE) for indirect connections through SFE ties. The IRA 2022 had limited FEOC rules only for EV battery supply chains; OBBBA 2025 expanded the PFE framework to virtually all clean energy credits.

Structural Risk Analysis

The 25% Ownership Threshold

The math behind Foreign-Influenced Entities (FIEs), and how contamination spreads through a supply chain.

Establishing that your immediate supplier isn't a Specified Foreign Entity (SFE) is the easy part. The hard part is proving they aren't a Foreign-Influenced Entity (FIE).

The Triggers

According to the Notice provisions, an entity becomes an FIE through a material relationship to an SFE. The most critical triggers are equity-based:

01
The 25% Single Limit≥25% equity ownership by a single SFE
02
The 40% Aggregate Limit≥40% aggregate equity ownership by multiple SFEs
03
Debt & Control Hooks≥15% SFE debt, or effective control via licensing/board seats

Calculating Indirect Ownership

The 25% threshold gets hard once ownership is tiered. Say Company A is 50% owned by a Chinese state enterprise, which makes it an SFE, and Company A owns 30% of Company B. Working out whether Company B crosses the threshold takes careful, step-by-step tracing.

Hidden ownership automatically triggers a CAUTION flag. If a tier-1 supplier's ownership is generic or obscured, sits above the 25% threshold, and has no jurisdiction confirmed, they are a real risk to your certification.

This is why Verdex traces ownership against canonical entity data (GLEIF, OpenCorporates) rather than trusting a supplier's own disclosures. The 25% threshold gets checked against the real ownership graph, not a form someone filled out.
