New IRS FDDEI Proposal: What International Founders Selling to Foreign Markets Should Know
Updated: September 14, 2026
Topic: Foreign-derived deduction eligible income, section 250, U.S. corporations, and international sales
The IRS has highlighted proposed regulations that would clarify how certain property sales and other dispositions are treated when calculating foreign-derived deduction eligible income (FDDEI) under section 250. The proposal may matter to U.S. domestic corporations that earn qualifying income from foreign markets, including some companies owned or operated by international founders. [1] [2]
The proposal is not final law and does not create an automatic tax benefit for every non-U.S. owner, U.S. LLC, or online seller. It addresses a specific corporate deduction framework, and the proposed rules would apply only when the taxpayer and income satisfy the statutory and regulatory requirements. Written comments are due October 5, 2026. [1]
For international entrepreneurs, the practical takeaway is to separate three questions: whether the business is a U.S. domestic corporation, whether its income may qualify as FDDEI, and whether the proposed treatment becomes final. An ITIN, EIN, LLC formation, or foreign customer base alone does not answer any of those questions.
What did the IRS and Treasury propose?
The proposed regulations are identified as REG-117130-25 and were published in the Federal Register on August 20, 2026, as document 2026-17019. The proposal concerns the application of section 250(b)(3)(A)(i)(VII) to sales or other dispositions of property and the calculation of deduction eligible income used in the FDDEI deduction. [1]
The IRS summarized the proposal in Internal Revenue Bulletin 2026-38, dated September 14, 2026. The bulletin states that the proposed regulations would provide for the exclusion of certain income from the calculation of deduction eligible income for the FDDEI deduction. [2]

What is FDDEI?
FDDEI is a statutory category used in the section 250 deduction framework. In broad terms, it relates to certain income earned by a domestic corporation from serving foreign markets. The technical calculation can involve deduction eligible income, foreign-derived ratio rules, the type of property or service, the customer’s location, and documentation supporting the transaction.
The proposal is not a general “international founder deduction.” It is not an ITIN benefit, an EIN benefit, or an LLC-formation benefit. The relevant taxpayer is generally a domestic corporation that may have qualifying foreign-derived income and must apply detailed rules to calculate the deduction.
A corporation that sells to foreign customers may need to review whether the transactions involve property, services, software, intellectual property, or other categories subject to distinct statutory requirements. The classification of the seller, the buyer, the transaction, and the property can affect the result.
Why does the property-sales proposal matter?
The Federal Register document addresses the treatment of certain income from sales or other dispositions of property when calculating deduction eligible income. It includes proposed rules concerning intangible property, other property, sales, and software transactions. [1]
The proposal’s subject matter matters because a company may have foreign customers without every dollar of foreign-market revenue qualifying for FDDEI. The tax analysis can depend on what was sold, who acquired it, where the property was used, how the sale was structured, and whether the income falls within an excluded category.
The proposed regulations are intended to provide administrable standards and clarify how the statutory language should be applied. Until the rules are finalized, taxpayers should identify which positions are based on current law, existing guidance, or the proposal itself.
Who could be affected?
The Federal Register states that the proposed regulations would affect domestic corporations with foreign-derived deduction eligible income. [1] This can include a U.S. corporation that sells products or services to non-U.S. customers, subject to the detailed requirements.
A corporation with an international owner may be within the potential audience, but foreign ownership alone does not establish eligibility. The business must first be the right type of taxpayer and then analyze its income and transactions under section 250.
The proposal may be relevant to companies with:
- Foreign customers purchasing products or services from a U.S. corporation.
- Cross-border software or digital-service transactions.
- Sales involving intangible property or other property.
- International supply, distribution, or licensing arrangements.
- Separate U.S. and foreign entities that transact with one another.
These categories are starting points for review, not conclusions that the income qualifies.
Why an LLC may not receive the deduction directly
Many international founders begin with a U.S. LLC because an LLC can provide a state-law business structure and may be practical for operations. However, an LLC is not automatically a domestic corporation for every federal tax purpose. Its federal tax classification may depend on elections, ownership, and applicable tax rules.
A single-member LLC may be treated differently from a partnership or a corporation. An LLC can elect corporate tax treatment in some circumstances, but the election, effective date, filing obligations, and tax consequences require a fact-specific analysis.
Therefore, a founder should not assume that forming an LLC creates FDDEI. The business must determine its federal tax classification and whether the statutory section 250 requirements apply. An EIN identifies the business for federal tax administration; it does not decide the entity’s tax classification or guarantee a deduction.
What records should an international business maintain?
A company considering a foreign-derived income position should maintain records that show the legal identity of the seller, the customer’s location, the nature of the property or service, the contract terms, the delivery or use location, the transaction value, and the related accounting treatment.
The documentation may include invoices, contracts, customer addresses, shipping records, product descriptions, software or licensing agreements, payment records, delivery evidence, and internal analyses supporting the foreign-market characterization. The exact records depend on the transaction and the final rules.
| Record category | Why it may matter |
|---|---|
| Entity and tax classification | Identifies whether the taxpayer is a domestic corporation and how it files |
| Customer location | Helps analyze whether the transaction is foreign-derived under applicable rules |
| Product or service description | Supports the classification of property, software, service, or intangible property |
| Contracts and invoices | Shows the parties, terms, price, and transaction structure |
| Delivery or use evidence | May help support where property or services were provided or used |
| Accounting reconciliation | Connects the tax position to books and filed returns |
A foreign founder should also keep the U.S. corporation’s records separate from those of a foreign parent, foreign affiliate, or personally owned entity. Related-party transactions require careful documentation and may involve additional U.S. tax and reporting rules.
What is still uncertain?
Because the rules are proposed, several details may change. The Federal Register document requests comments on the proposed treatment and invites public input before the Treasury Department and IRS decide what final guidance should say. [1]
The proposal does not make every relevant transaction eligible, and the IRS may revise the language after reviewing comments. Taxpayers should not claim a deduction solely because a transaction appears to fit a summary of the proposal.
The IRS Internal Revenue Bulletin itself cautions that its synopses are aids for identifying subject matter and may not be relied upon as authoritative interpretations. [2] The full proposed rule and any later final regulations should be reviewed for technical positions.
What should international founders do before October 5?
Determine the entity’s federal tax classification
Identify whether the business is a C corporation, an S corporation where eligible, a partnership, a disregarded entity, or another classification. Do not use “LLC” as a substitute for the federal tax classification.
Separate current law from proposed guidance
Mark each position as based on enacted law, existing final regulations, published IRS guidance, or the new proposal. A proposed regulation is not the same as a final rule.
Review foreign revenue by transaction type
Group foreign revenue by product, service, software, licensing, intangible property, and other categories. Identify the customer, location, contract party, and delivery or use facts for each category.
Preserve supporting records
Build a transaction file that connects the income calculation to contracts, invoices, customer information, delivery records, and accounting data. A tax result should be supported by contemporaneous records rather than a post-filing assumption.
Consider submitting a public comment
Interested parties can review the Federal Register document and submit written comments through the official rulemaking process by October 5, 2026. Comments may address the practical effect on businesses, documentation burdens, technical interpretations, and implementation concerns.
How ITIN, EIN, and LLC services fit into this issue
An ITIN is an IRS-issued federal tax-processing number for an eligible individual who cannot obtain an SSN. An EIN is an IRS-issued business tax identifier. An LLC is formed under state law. None of these items independently establishes FDDEI eligibility or guarantees a section 250 deduction.
ITIN.com can prepare and coordinate eligible ITIN, EIN, and LLC formation services, along with banking-assistance preparation. ITIN.com does not determine a company’s federal tax classification, calculate a section 250 deduction, issue a tax ruling, or guarantee that a proposed tax position will be accepted.
The IRS issues ITINs and EINs, states form LLCs, and banking partners decide account approval. ITIN.com prepares, verifies, files, coordinates, and guides. A qualified tax adviser should review any FDDEI calculation or position under proposed regulations.
Bottom line
The IRS’s September 14, 2026 Internal Revenue Bulletin highlights proposed regulations that could clarify how certain property sales and other dispositions are treated when calculating FDDEI. The proposal may matter to U.S. domestic corporations serving foreign markets, including some companies owned by international founders.
It is not a final rule and is not an automatic tax benefit for every non-U.S. entrepreneur, LLC, EIN holder, or online seller. Review the entity’s federal classification, analyze foreign transactions carefully, preserve supporting records, and consider the October 5 comment deadline. The final result will depend on enacted law, final guidance, and the taxpayer’s facts.
