Subpart F Income 2026: Which Foreign-Owned LLC Distributions Trigger US Taxation
If you’re a non-US founder who formed a US LLC or C-Corp, understanding Subpart F income could save you thousands in unexpected US taxes. This rule affects international entrepreneurs who own controlling stakes in foreign companies or receive distributions from US entities.
Here’s what changed in 2026 and what it means for your US business structure.
What Is Subpart F Income and Why Should You Care?
Subpart F income is a critical component of U.S. international tax law, designed to prevent the indefinite deferral of U.S. taxation on certain types of income earned by controlled foreign corporations (CFCs). But here’s the catch: it also applies to distributions from US entities if you have certain foreign ownership structures.
Those affected by Subpart F rules include US shareholders holding at least 10% ownership in a CFC. Even if you receive no distributions, you may owe US taxes on the income your company earns.
For non-US founders, this means that forming a US LLC doesn’t automatically shield you from immediate US taxation on your business income. Understanding which distributions trigger taxes is essential for smart tax planning.
The 2026 Tax Law Changes: GILTI Becomes NCTI
The GILTI regime is terminated for tax years beginning after December 31, 2025 and is replaced by a “net CFC tested income” (NCTI) regime. This is one of the biggest changes affecting international business owners in 2026.
What does this mean in plain English? The old rules that allowed you to shelter income based on tangible assets are mostly gone. The 10% QBAI return is eliminated, so capital-intensive CFCs that previously generated little or no GILTI may now produce sizeable NCTI inclusions.
For foreign founders with US LLCs or C-Corps, this translates to potentially higher US tax bills starting in 2026. If your business relies on physical assets (equipment, inventory, real estate), you no longer get a free pass on a portion of your profits.
What Types of Income Trigger Subpart F Taxation?
Whereas the Subpart F rules are aimed at a CFC’s passive (e.g., dividends, interest, royalties) income, the NCTI rules are aimed at a CFC’s active (e.g., business, trading) income.
Here are the main categories of income that trigger immediate US taxation:
- Foreign Base Company Sales Income (FBCSI): Foreign base company sales income includes profits, commissions, and fees derived from buying and selling tangible property in which a related person is buyer or seller. Therefore, Subpart F income will arise if profits are: Generated from related parties. Earned outside the country where the product is manufactured. outside the country where the product is sold for use.
- Passive Income: Interest, dividends, and royalties earned by your foreign company are taxed immediately in the US.
- Services Income: FBC services income includes income earned from technical, managerial, industrial, and similar services. Services are performed outside of the country of incorporation.
- Insurance Income: Income from providing insurance to related parties.
Important Exceptions That Can Reduce or Eliminate Your Tax
The good news? Not all foreign income triggers immediate US taxation. There are three major exceptions that could help you avoid Subpart F taxes entirely.
1. The High-Tax Exception
The High Tax Exception can eliminate GILTI entirely if your foreign corporation pays a local tax rate of at least 18.9% (2025) or approximately 14% (2026 under NCTI). Many expats working in countries such as the UK, Germany, France, Japan, and Australia already exceed this threshold.
If your foreign company operates in a country with higher corporate taxes, you may not owe any additional US tax. This is where working with tax professionals becomes invaluable for international founders.
2. The De Minimis Rule
De Minimis Rule exception: Subpart income (certain categories) is less than $1,000,000 or 5% of the CFC’s gross income. If your Subpart F income falls below these thresholds, you may be able to exclude it from US taxation.
3. Same-Country Exception
Same country sales/use exception: Income derived from the sale or disposition of property within CFC’s country of incorporation is not considered FBCSI. If all your sales occur in the country where your company is incorporated, this exception can help.
How Distributions Trigger Taxation
Subpart F assumes that shareholders receive a proportionate share of certain categories of a controlled foreign corporation’s (CFC) current earnings and profits. US shareholders must report Subpart F income in the United States regardless of whether the CFC makes a distribution.
This is critical: you don’t need to actually take money out of your company to owe US taxes. Even if your profits stay in the foreign company’s bank account, you still report them on your US tax return.
When you do take distributions, those are taxed differently. By properly tracking and applying PTI, US expats can significantly reduce the risk of paying tax on income twice–once when it’s included in your tax return under Subpart F or GILTI, and again when it is distributed as a dividend from the CFC. This concept is called “previously taxed income” (PTI).
Form 5471 and Form 5472: What You Must File
Foreign-owned US LLCs must file Form 5472 with a basic Form 1120 if they have transactions with related parties. A foreign-owned US LLC is a domestic disregarded entity, yet when wholly owned by a foreign person, it must file a pro forma Form 1120 with Form 5472.
Additionally, the form now includes a new Schedule H-1 specifically for reporting your controlled foreign corporation’s adjusted net income or loss for corporate alternative minimum tax (CAMT) purposes. This replaces the previous Worksheet H-1 and reflects recent tax law changes.
These forms are mandatory for non-US founders with US entities, and The $10,000 penalty for Form 5471 is now more strictly enforced via automated IRS matching.
The New NCTI Tax Rate and Section 250 Deduction
Effective corporate rate rises to approximately 12.6% – reflecting the 40% §250 deduction that applies to NCTI (21% × 60% = 12.6%). This is slightly higher than the previous GILTI rate, which means international founders will see higher US tax bills.
However, Starting in 2026, 90% of foreign income taxes can help offset NCTI. This improved foreign tax credit can significantly reduce your US tax liability if your foreign company pays substantial taxes abroad.
To properly calculate your NCTI obligations, you’ll need to file Form 8992 is used by US shareholders. Getting this right is crucial for avoiding penalties and overpaying taxes.
Pro Rata Share Changes for 2026
For CFC years beginning after December 31, 2025, new rules will allocate Subpart F and GILTI income to US shareholders who own stock at any time during the year, not just on the last day. This is important if you’re planning to buy or sell shares in a foreign company—timing matters now more than ever.
Common Tax Planning Strategies for International Founders
As an international founder with a US entity, you have several options to minimize Subpart F taxation:
- The Section 962 Election: The Section 962 election lets you be taxed at the corporate rate (21%) instead of the individual rate, often providing substantial savings. This is especially useful for high-income founders.
- Disregarded Entity Election: Available only for single-owner CFCs, this treats your corporation as a disregarded entity for U.S. tax purposes. Primary benefit: Can use the Foreign Earned Income Exclusion to exclude up to $132,900 (2026 tax year) and avoid NCTI entirely. This strategy works best for solo founders.
- High-Tax Exception Structuring: Operate your business in a country with higher corporate taxes to qualify for automatic exemption from US taxation.
- Careful Related-Party Transaction Management: Document all transactions between your US and foreign entities to avoid triggering Subpart F sales income rules.

Frequently Asked Questions (FAQ)
Q1: Do I owe US taxes on Subpart F income if I don’t take distributions from my foreign company?
Yes. Subpart F assumes that shareholders receive a proportionate share of certain categories of a controlled foreign corporation’s (CFC) current earnings and profits. US shareholders must report Subpart F income in the United States regardless of whether the CFC makes a distribution. The income is attributed to you automatically in the year it’s earned by the foreign company.
Q2: What’s the difference between Subpart F income and NCTI (formerly GILTI)?
Whereas the Subpart F rules are aimed at a CFC’s passive (e.g., dividends, interest, royalties) income, the NCTI rules are aimed at a CFC’s active (e.g., business, trading) income. Subpart F targets easy-to-move income, while NCTI now captures a broader range of active business earnings because the tangible asset deduction was eliminated.
Q3: If my foreign company is taxed at 25%, do I still owe US NCTI tax?
Probably not. Under the NCTI regime a CFC will need to pay a tax rate of 14% in order for its US shareholder to not have an NCTI inclusion on an accrual basis. If your foreign company’s effective tax rate exceeds approximately 14%, the high-tax exception can eliminate your US tax liability on NCTI.
Q4: What forms do I need to file for Subpart F income reporting?
The main forms depend on your entity structure. Foreign-owned US LLCs must file Form 5472 with a basic Form 1120 if they have transactions with related parties. A foreign-owned US LLC is a domestic disregarded entity, yet when wholly owned by a foreign person, it must file a pro forma Form 1120 with Form 5472. For CFCs, you’ll also file Form 5471 and Form 8992 (for NCTI calculations).
Q5: How can I minimize Subpart F and NCTI taxes as an international founder?
There are several strategies: (1) Qualify for the high-tax exception by operating in a higher-tax country; (2) Make a Section 962 election to be taxed at the corporate rate; (3) Structure your entity as a disregarded entity and use the Foreign Earned Income Exclusion; (4) Carefully document all related-party transactions to avoid triggering Subpart F sales income; and (5) Work with a tax professional to model the best structure for your specific situation.
