In short
When two companies under common control transfer or license an AI model between them, the price must be what unrelated parties would have set under the same circumstances. That is the arm’s length standard under IRC §482. Treas. Reg. §1.482-1(b)(1)
Because AI models often generate large income well after the original transaction, a special rule applies. The price must be commensurate with the income the intangible produces over time. If actual profits later prove much higher than the original price assumed, the IRS can adjust the price in a later year, even if the original year is closed. IRC §482, Treas. Reg. §1.482-4(f)(2), IRS guidance, Treas. Reg. §1.482-4(f)(2), Treas. Reg. §1.482-4(f)(2)
Key safe harbors exist. If actual profits stay within 80% to 120% of what the pricing analysis projected, and the taxpayer meets certain conditions, periodic adjustments are generally blocked. But recent IRS guidance makes clear that when no exception applies, the adjusted arm’s length price is final. The taxpayer cannot simply argue that the original price was reasonable at the time. IRS AM 2025-001
For AI model intellectual property, the residual profit split method is available when the controlled transaction involves nonroutine intangible contributions, and transfer pricing documentation is essential to avoid penalties that can reach 40% of the underpayment. Treas. Reg. §1.6662-6, Treas. Reg. §1.482-6
How does IRC §482 apply to AI model intellectual property?
The statute does three things. It gives the IRS broad power to reallocate income among commonly controlled taxpayers when a transaction does not clearly reflect income. It adds a special standard for intangible property. And it lets the IRS require aggregate valuation.
The arm’s length standard is the core test. The results of a controlled transaction must match what independent parties would have done in the same circumstances. For a license of an AI model from a U.S. parent to an Irish subsidiary, the royalty rate must resemble what the parent would charge an unrelated licensee. Treas. Reg. §1.482-1(b)(1)
Congress added the commensurate with income standard in 1986 because it found that taxpayers were undervaluing high profit intangibles in controlled deals. The price must be commensurate with the income attributable to the intangible. This means the IRS can look at actual income generated after the transfer, not only projected income. IRC §482
A third sentence, added in 2017, requires the IRS to value intangibles on an aggregate basis or based on realistic alternatives when those are the most reliable approaches. The Tax Cuts and Jobs Act inserted this language. IRC §482
All three parts work together when a controlled group develops an AI model in one entity and uses it to generate revenue in another.
What AI assets count as intangible property under the regulations?
The regulatory definition is broad
The regulation defines intangible property to include patents, inventions, formulas, processes, designs, know how, copyrights, trademarks, trade names, programs, systems, surveys, studies, customer lists, and any other similar item that derives value from intellectual content rather than physical attributes. AI model weights, training data that qualifies as a trade secret, and certain algorithms can fall within the broad categories listed in this definition, including know-how, processes, methods, programs, and technical data. Treas. Reg. §1.482-4(b)
To be property rather than a service, training data must generally qualify as know how or a trade secret. If the data is not secret, it likely would not be treated as property. Tax alert
The federal digital content rules under §§1.861-18 and 1.861-19 classify cloud transactions solely as services and exclude non copyrightable data from the definition of digital content. So the provision of user data for AI training may fall entirely outside the §861 framework and must be classified under general tax and §482 principles. Treas. Reg. §1.861-18, Tax alert
Three classification pathways for an AI model transaction
The same AI model can be handled three different ways depending on the deal structure, and each path brings different permissible pricing methods.
| Classification | Example transaction | Primary pricing method | Reference |
|---|---|---|---|
| Transfer of intangible property | License of model weights and underlying algorithms | CUT, CPM, profit split, unspecified | §1.482-4 |
| Provision of services | Access to a trained model hosted by the owner, no rights transferred | Services cost method, CPM, comparable uncontrolled services price | §1.482-9 |
| Transfer of tangible property | Delivery of a copy of the model file with no IP rights | CUP, cost plus, resale price | §1.482-3 |
Most significant AI model transactions are structured as intangible transfers or service arrangements, and the distinction drives the method choice.
How do you price an AI model transaction?
The four methods for intangible transfers
The regulations list four methods for pricing a transfer of intangible property. No single method has automatic priority. The best method rule requires the method that produces the most reliable arm’s length result based on comparability and data quality. Treas. Reg. §1.6662-6(d)
- Comparable uncontrolled transaction method. Compares the controlled transaction to a similar deal between unrelated parties involving the same or a comparable intangible under similar circumstances.
- Comparable profits method. Tests whether the profit of the tested party falls within a range of profits earned by similar uncontrolled companies.
- Profit split method. Splits the combined profit from the controlled transaction based on the relative value of each party’s contributions.
- Unspecified methods. Any other method that yields a reliable arm’s length result.
Why the profit split method often fits AI
AI model development inside a multinational group usually involves multiple entities making unique, hard to value contributions. One entity develops the core algorithm, another contributes proprietary training data, a third handles domain expertise and ongoing refinement. These are non routine DEMPE contributions (development, enhancement, maintenance, protection, and exploitation of intangibles). Finding truly comparable uncontrolled transactions for such a bundle is nearly impossible.
The residual profit split method addresses this. First, each participant receives a routine return benchmarked to comparable companies. The remaining residual profit is then split based on the relative value of the non routine contributions. Treas. Reg. §1.482-6
The OECD identifies three indicators that favor a profit split, including unique and valuable contributions by each party, highly integrated business operations, and shared assumption of economically significant risks.OECD
Multiple practitioner analyses identify the residual profit split as a more defensible approach for AI-generated IP. Tax alert
The CUT method faces comparability hurdles
A pure comparable uncontrolled transaction method requires a transaction involving the same or a truly comparable intangible. AI model weights are unique assets. No two large language models are identical. Even open source models differ materially in architecture, training data, and performance. This makes a reliable CUT search difficult, though not impossible if an appropriate comparable license grant exists.
What are periodic adjustments and how do they affect AI transactions?
The IRS can look back at actual profits
The commensurate with income standard means that the price of an intangible must reflect the income it actually generates, not just what the parties predicted when they set the price. The IRS can make a periodic adjustment in a later taxable year even if the original transfer year is closed under the normal three year statute of limitations. Treas. Reg. §1.482-4(f)(2)
For an AI model that suddenly becomes the core of a billion dollar revenue stream five years after the intercompany license was signed, the IRS can reopen the pricing and demand additional tax based on ex post results.
The 80% to 120% exception
The periodic adjustment rule contains a important safety valve. If actual profits fall within 80% to 120% of the profits the taxpayer reasonably projected when setting the price, no periodic adjustment can be made, provided certain conditions are met. For a CUT method, the intangible must be comparable and all circumstances substantially identical. For other methods, the taxpayer must meet the documentation requirements. Treas. Reg. §1.482-4(f)(2)(ii)(B)(6), Treas. Reg. §1.482-4(f)(2)(ii)(C)(4)
The five year rule provides additional certainty. If all the requirements of Treas. Reg. §1.482-4(f)(2)(ii)(B) or (f)(2)(ii)(C) (which include the 80% to 120% test) are met for each year of the five year period beginning with the first year in which substantial periodic consideration was required to be paid, no periodic adjustment may be made in any later year. Treas. Reg. §1.482-4(f)(2)(ii)(E)
Extraordinary events beyond the taxpayer’s control also block adjustments if they could not reasonably have been anticipated.
AM 2025-001 raises the stakes
On January 17, 2025, the IRS Office of Chief Counsel released a generic legal advice memorandum that changed the enforcement posture. When no exception to periodic adjustments applies, the arm’s length price determined by the periodic adjustment rules is definitive. The taxpayer cannot overcome it by arguing that the original price was set in good faith under the general arm’s length standard. IRS AM 2025-001
The memorandum also clarified that income for the commensurate with income standard means income the intangible actually generated after the transaction, evaluated on an ongoing basis. This directly reversed the IRS’s own 2007 guidance, which had limited the inquiry to what a reasonable taxpayer would have projected at the time of transfer. IRS AM 2025-001, IRS AM 2007-007
Periodic adjustments are one directional. Only the IRS can make them. A taxpayer cannot use the commensurate with income standard to lower a price the IRS has already accepted. IRS AM 2025-001
If actual profits from an AI model substantially exceed the profits assumed in the original pricing analysis, and no exception applies, the IRS will adjust the transfer price to match reality. A well reasoned pricing report at the time of the deal will not by itself stop the adjustment.
One open question commentators have raised is that AM 2025-001 treats the 80% to 120% range as a trigger for adjustments, but the regulation text frames that range as an exception component rather than an affirmative trigger. The regulation does not contain an explicit periodic adjustment trigger equivalent to the PRRR trigger found in the cost sharing rules. Tax alert
This tension may be litigated, and courts will need to reconcile the IRS’s position with the regulatory requirement that periodic adjustments must be consistent with the arm’s length standard. AM 2025-001, Treas. Reg. §1.482-4(f)(2)(i)
Cost sharing arrangements use a different range
For a cost sharing arrangement involving a platform contribution transaction, the IRS uses the Actually Experienced Return Ratio. If the AERR falls outside the Periodic Return Ratio Range of 0.667 to 1.5, the IRS may make a periodic adjustment. If the AERR stays within that range for the first ten years, further adjustments are barred. The PRRR narrows to 0.8 to 1.25 if sufficient documentation is not maintained annually. Treas. Reg. §1.482-7(i)(6)
What documentation and penalties apply?
The §6662 documentation requirements are specific
To avoid penalties, a taxpayer must prepare principal documents that include a business overview, an organizational structure, a description of the chosen transfer pricing method and why alternatives were rejected, a description of the controlled transactions, information on any comparables and adjustments, economic and financial projections, any post year end data available before the tax return is filed, and an index of all principal and background documents. The documents must exist when the return is filed and must be provided to the IRS within 30 days of a request. Treas. Reg. §1.6662-6(d)(2)(iii)(A)
The penalty framework is two layered
| Penalty type | Threshold | Penalty rate |
|---|---|---|
| Net adjustment penalty | Net §482 adjustment exceeds lesser of $5 million or 10% of gross receipts | 20% of underpayment |
| Gross valuation misstatement penalty | Net adjustment exceeds lesser of $20 million or 20% of gross receipts | 40% of underpayment |
| Transactional penalty | Price is 200% or more of arm’s length amount (or 50% or less) | 20% of underpayment |
| Transactional penalty (higher) | Price is 400% or more of arm’s length amount (or 25% or less) | 40% of underpayment |
Enforcement is intensifying
At a TEI conference in September 2024, IRS Director of Field Operations Brad Anwyll stated that the IRS is now more willing to assert penalties even when transfer pricing documentation exists, and the agency is hiring roughly 70 new economists, tax specialists, and revenue agents for the transfer pricing practice. Tax alert
An IRS Chief Counsel attorney added that both the documentation and the chosen method must be reasonable. Having a report is not enough. The report and the price must both hold up. Tax alert
What can practitioners learn from the major transfer pricing cases?
Three recent Tax Court decisions offer a roadmap for AI model transactions, even though none involved AI directly.
Coca-Cola taught the power of the CPM and the limits of contractual labels
The IRS reallocated more than $9 billion in aggregate taxable income from foreign supply points back to the U.S. parent over three tax years. The Tax Court upheld the IRS’s comparable profits method, rejected the company’s CUT and residual profit split alternatives, and held that the foreign subsidiaries did not own marketing intangibles because no contract granted them ownership. A 1996 closing agreement did not bind the IRS for later years. Coca-Cola deposited $6 billion with the Treasury and appealed to the Eleventh Circuit. The company’s 2023 financial statements estimated potential aggregate incremental tax and interest liability of roughly $16 billion if the IRS position applies through 2023. Coca-Cola Co. v. Comm’r, 155 T.C. 145 (2020), Tax alert
The lesson for AI is that a foreign subsidiary that merely distributes or deploys an AI model developed in the United States will not acquire ownership of the model’s intangible value simply by operating it. Ownership follows formal agreements, and the IRS will look through the form.
Facebook showed the income method can work, but inputs must be reasonable
The dispute involved the 2010 platform contribution transaction payment from Facebook Ireland to Facebook US under a cost sharing arrangement. The Tax Court held that the income method was the best method because only Facebook US made nonroutine platform contributions. However, the IRS used unreasonable inputs, including $1.9 billion in aspirational revenue from the CEO’s projections, used an inappropriate discount rate, and applied a cost plus 8% markup when the median comparable profits method analysis showed a 13.9% markup. The court recalculated the payment at $7.786 billion, down from the IRS’s $19.945 billion. Facebook, Inc. v. Comm’r, 164 T.C. No. 9 (2025), Tax alert
The lesson is that when pricing an AI model’s platform contribution, the inputs matter as much as the method. Using aspirational revenue forecasts rather than supportable projections will invite a challenge and may lead to a court determined value, but not one the taxpayer controls.
Medtronic revealed the court’s occasional willingness to create its own method
The Tax Court rejected both the IRS’s CPM and the taxpayer’s CUT method and crafted its own unspecified method with a blended 48.4% royalty rate. Both parties appealed. Medtronic, Inc. v. Comm’r
Notably, the Facebook court declined to craft its own method, suggesting the Tax Court may be moving away from the Medtronic approach. The lesson is that an AI taxpayer cannot assume a court will split the difference. The method must be defensible on its own.
Special considerations for AI model intellectual property
Classification uncertainty remains
No IRS guidance exists that is specific to AI model weights, embeddings, or neural network parameters. Practitioners must fit these assets into the existing categories, namely formula, program, system, method, or know how. Most fit, but the absence of explicit authority creates risk. User data for AI training could be treated as a service, tangible property, or intangible property depending on the transaction structure. Tax alert
DEMPE analysis must capture the full development chain
AI models often involve multiple entities contributing training data, algorithm design, compute resources, and ongoing fine tuning. A thorough DEMPE analysis is necessary to support the profit split allocation under the residual method. Each entity’s functions, assets, and risks must be mapped to the value it creates.
The OECD framework informs but does not bind
The OECD Transfer Pricing Guidelines treat ex post results as presumptive evidence of an intangible’s value, but that evidence is rebuttable. The U.S. CWI standard and AM 2025-001 go further by making the ex post result definitive when no exception applies. The U.S. does not incorporate the OECD guidelines by reference, though the U.S. maintains the regulations are consistent with them. IRS legal advice, OECD U.S. transfer pricing profile
The Loper Bright effect is unresolved
The Supreme Court’s rejection of Chevron deference in 2024 may open challenges to Treasury’s §482 regulations. The Facebook court independently reviewed the 2009 cost sharing regulations under Loper Bright and upheld them. But other provisions, including the periodic adjustment rules that override the statute of limitations, could face renewed challenge.
Repatriation options exist under new §367(d) rules
Final regulations effective October 10, 2024 allow a U.S. parent to terminate ongoing §367(d) income inclusions when previously transferred intangible property is repatriated to a qualified domestic person. A qualified domestic person excludes partnerships and S corporations. This offers a planning tool for groups that outgrow an initial offshore structure for their AI model IP. T.D. 9994
Key takeaways
- Section 1.482-4(b) defines intangible property broadly to include processes, methods, programs, technical data, know-how, and other items that derive value from intellectual content. The classification drives the permissible pricing methods. Treas. Reg. §1.482-4(b)
- The residual profit split method is a practical solution for AI-generated IP. It splits routine returns first, then allocates residual profit based on non routine contributions. OECD, Tax alert
- The commensurate with income standard allows the IRS to adjust prices based on actual profits years later. If no exception applies, the adjusted price is final. IRC §482, IRS AM 2025-001
- The periodic adjustment exceptions in Treas. Reg. §1.482-4(f)(2)(ii) bar adjustments if, among other requirements, aggregate actual profits remain between 80% and 120% of the prospective profits foreseeable when the controlled agreement was entered into. Plan to track this annually. Treas. Reg. §1.482-4(f)(2)(ii)
- Documentation must be ready when the return is filed and delivered within 30 days of an IRS request. Both the method and the documentation must be reasonable to avoid penalties. Treas. Reg. §1.6662-6(d)(2)
- Penalties reach 40% of the underpayment for large adjustments and can apply even when a report exists. The IRS is adding staff and is more willing to assert penalties. Tax alert
- Recent cases show that contractual terms control ownership. The court analyzed who performed the key functions and bore the risks, but held that contractual terms control ownership and only the Commissioner may set them aside. Coca-Cola, 155 T.C. 145, Facebook, 164 T.C. No. 9
Frequently asked questions
Q:Does IRC §482 apply to an open source AI model transferred between controlled entities?
A:Yes, if the transaction involves any intangible rights that produce income. Even an open source model may carry value through proprietary modifications, compiled weights, or exclusive access arrangements. The fact that the base model is publicly available does not eliminate the need for an arm’s length price for the specific rights transferred.
Q:Which transfer pricing method is best for AI model transactions?
A:No method is presumptively best. The best method rule requires the most reliable measure under the facts. In practice, the residual profit split method is often the most defensible because AI models are unique and tend to involve integrated contributions from multiple entities. But the taxpayer must document why the chosen method is more reliable than the alternatives. Treas. Reg. §1.482-1(c)
Q:What happens if the IRS makes a periodic adjustment years after the original return was filed?
A:The adjustment stands, even if the original year’s statute of limitations has expired. The commensurate with income standard allows a periodic adjustment without regard to whether the statute of limitations for the original transfer year remains open. The IRS may make such an adjustment unless the taxpayer satisfies an exception. Certain of the exceptions require, among other things, that aggregate actual profits are not less than 80% nor more than 120% of prospective profits. Treas. Reg. §1.482-4(f)(2)
Q:Can a taxpayer use the commensurate with income standard to lower a transfer price?
A:No. Periodic adjustments under §1.482-4(f)(2) can only be initiated by the IRS. If actual profits turn out lower than projected, the taxpayer cannot use that to reduce a previously accepted price. This one way nature is confirmed by AM 2025-001. IRS AM 2025-001
Q:How does the periodic adjustment rule differ from the cost sharing PRRR rule?
A:Both allow the IRS to adjust prices based on ex post results, but the mechanics differ. The intangible property rule under §1.482-4(f)(2) uses the 80% to 120% profit range and a five year forward safe harbor. The cost sharing rule under §1.482-7(i)(6) uses an Actually Experienced Return Ratio range of 0.667 to 1.5 and a ten year safe harbor. The cost sharing rule also narrows the range to 0.8 to 1.25 if documentation is insufficient. Treas. Reg. §1.482-7(i)(6), Treas. Reg. §1.482-7(i)(6)(ii), Treas. Reg. §1.482-7(i)(6)(vi)
Q:Is AM 2025-001 binding precedent?
A:No. As a generic legal advice memorandum, it cannot be used or cited as precedent. But it reflects the current litigation position of the IRS Office of Chief Counsel and will guide IRS agents during audits and may influence Appeals’ assessment of litigation hazards. Practitioners should treat it as a clear statement of the IRS’s view. IRS AM 2025-001
Q:What documentation is required to avoid penalties on an AI model transaction?
A:The taxpayer must prepare and maintain principal documents that describe the business, the organizational structure, the controlled transactions, the method selected and why alternatives were rejected, any comparables and adjustments, economic and financial projections, post year end data, and an index. The documents must exist when the return is filed and be provided within 30 days of an IRS request. The method itself must be reasonable. Treas. Reg. §1.6662-6(d)(2)(ii), Tax alert
Q:Does the OECD transfer pricing framework bind U.S. taxpayers?
A:No. The OECD Transfer Pricing Guidelines are not incorporated into U.S. law, except for a single cross reference in Notice 2025-04 for the Simplified and Streamlined Approach. However, the U.S. regulations are stated to be consistent with the OECD guidelines, and the IRS and courts sometimes reference them. The U.S. CWI standard is more stringent than the OECD’s HTVI guidance on ex post evidence. OECD, Tax analysis
Q:What is the practical effect of the 2024 Loper Bright decision on §482 rules?
A:The Facebook court upheld the 2009 cost sharing regulations after conducting an independent review under Loper Bright, meaning the court did not defer to Treasury’s interpretation. Other provisions, such as the periodic adjustment rules that extend the statute of limitations, may face future challenges. The full effect is still developing.
Q:Can a U.S. group bring AI model IP back from a foreign subsidiary without ongoing §367(d) income?
A:Yes, for repatriations to a qualified domestic person that is not a partnership or S corporation, and only for transfers occurring on or after October 10, 2024. Final regulations provide specific reporting requirements. This can terminate future §367(d) inclusions. TD 9994
