Transfer Pricing in Latin America: When It Applies to You
Before a US parent or international group wires a payment to its Colombian or Mexican subsidiary, finance needs to know whether that payment triggers transfer pricing documentation, at what threshold, and with what filing, as of September 2026.
A US parent wiring a monthly management fee to its Colombian subsidiary, or a Mexican subsidiary invoicing services back to its US parent, is not making a routine intercompany transfer. It is carrying out a related party transaction, and that triggers a tax regime with its own threshold, its own documentation, and its own filing deadline in each country involved.
In Soulbit Academy we already covered Colombia's withholding tax on payments abroad, the rule that applies when a Colombian company pays an unrelated foreign supplier. This guide goes one step further: what counts as a related party, which thresholds trigger transfer pricing documentation and filing in Colombia and Mexico, what the arm's length principle requires, and what changes, if anything, when the related party payment moves in stablecoin.
What transfer pricing is and what counts as a related party
Transfer pricing is the set of conditions (price, margin, or profit) that two related parties agree on in a cross-border transaction, measured against what two independent parties would have agreed on in a comparable transaction. A related party is, broadly, a parent company, a subsidiary, or any entity in the same corporate group with which there is control, a relevant equity stake, or shared management.
The regime does not depend on any intent to lower a tax bill. It depends on two objective facts: a related party relationship between the two sides, and a transaction that crosses a tax border, usually because one party is a tax resident of a different country than the other, or because one of them operates through a tax haven.
Does a payment to an unrelated supplier also fall under transfer pricing?
A payment to a supplier with no equity, control, or management link to the paying company does not fall under transfer pricing rules, regardless of the amount. The trigger is the related party relationship, not the fact that a payment crosses a border. That kind of payment to an independent foreign supplier is governed by ordinary withholding tax rules, not by transfer pricing.
When the obligation applies in Colombia: gross assets and gross income thresholds
A Colombian entity becomes subject to transfer pricing rules when, at year end, its gross assets exceed 100,000 UVT or its gross income exceeds 61,000 UVT, and it carried out transactions with related parties abroad during that year. With the 2026 UVT set at COP 52,374 by DIAN Resolution 000238 of December 15, 2025, those thresholds equal roughly COP 5,237 million in gross assets or COP 3,195 million in gross income.
If the related party sits in a jurisdiction Colombia treats as a tax haven, the duty to prepare supporting documentation applies regardless of the paying entity's assets or income. Article 260-2 of Colombia's Tax Code, the base rule for the local regime, carves out no exception for a smaller entity in that scenario.
Colombia's transfer pricing informative return is filed on Form 120 with DIAN. The supporting documentation, which backs the arm's length analysis, is made up of a Local File and, when the size of the multinational group requires it, a Master File. Per DIAN's official filing calendar, the 2026 window for both obligations runs from September 9 to September 22, depending on the last digit of the taxpayer's tax ID, and the Country-by-Country report, when it applies, is due by December 15, 2026. This runs in parallel to the duty we already covered around Colombia's foreign exchange regime for companies and DIAN's crypto asset reporting rules, both of which require a similar dated record of counterparties.
When the obligation applies in Mexico: the Article 76 thresholds
A Mexican entity carrying out business activities must keep transfer pricing supporting documentation once its accumulated income in the immediately prior fiscal year exceeded MXN 13 million. The threshold drops to MXN 3 million when the income comes from professional services, under Article 76, sections IX and XII, of Mexico's Income Tax Law.
These two thresholds apply independently: a Mexican entity billing below MXN 13 million in general business activity, but above MXN 3 million in professional services, is still obligated. The duty requires documenting that transactions with related parties, whether inside or outside Mexico, were priced at market value, under the arm's length principle set out in Articles 179 and 180 of the same law. A group whose Mexican subsidiary also handles crypto assets should separately check its exposure under Mexico's Fintech Law for crypto assets, a different regime that shares the same documentation-first logic.
| Aspect | Colombia | Mexico |
|---|---|---|
| Threshold that triggers the obligation | Gross assets > 100,000 UVT or gross income > 61,000 UVT | Accumulated income > MXN 13,000,000 (business activity) or > MXN 3,000,000 (services) |
| Transactions with tax havens | Documentation duty applies regardless of amount | Same duty applies, no carve-out for related low-tax jurisdictions |
| Informative filing | DIAN Form 120 | Related party disclosure inside the annual return filed with Mexico's SAT |
| Supporting documentation | Local File and, when applicable, Master File | Documentation showing the method applied under Article 180 of the Income Tax Law |
| Legal basis | Articles 260-1 to 260-11, Colombian Tax Code | Articles 76, 179, and 180, Income Tax Law |
What if my group has subsidiaries in both Colombia and Mexico, with payments running between them?
A group with subsidiaries in both countries has to assess each transaction between them under both regimes at once, not under a single one. The payment the Colombian subsidiary makes to the Mexican one, or the reverse, can trigger the Colombian documentation duty if that subsidiary crosses the local asset or income thresholds, and independently trigger the Mexican duty if the Mexican subsidiary crossed its own accumulated income thresholds.
The arm's length principle and the methods the OECD recognizes
The arm's length principle requires that a transaction between related parties be priced under the same conditions two independent parties would have agreed to in a comparable transaction. It is the international standard behind both Colombia's Tax Code and Mexico's Income Tax Law, and it is developed in detail in the OECD's Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations. The United States enforces its own version of this principle domestically under Internal Revenue Code Section 482, a separate US filing duty that does not replace either country's local requirement.
The OECD guidelines recognize five methods to test whether a related party transaction meets the arm's length standard. The first is the comparable uncontrolled price method, which measures the agreed price directly against a similar transaction between independent parties. The second is the resale price method, which starts from the price at which the related buyer resells the good to a third party. The third is the cost plus method, which adds a profit margin to production or acquisition cost. The fourth is the transactional net margin method, which compares profitability indicators across comparable transactions. The fifth is the profit split method, reserved for transactions where both related parties contribute significant intangible assets and no direct comparable exists.
Both the Colombian and Mexican rules require choosing the method that best fits the nature of the transaction, not the one that produces the most favorable tax result. That choice has to be backed by a transfer pricing study, with a functional analysis of which assets, functions, and risks each related party assumes.
Documentation and informative filings: what a parent company needs from its LATAM subsidiary
Supporting documentation is the technical file that shows, transaction by transaction, that the price or margin agreed with a related party meets the arm's length principle. It includes a functional analysis of each party, the selection and application of the method, and a comparison against similar independent transactions or companies.
The informative return, by contrast, is the form where the entity reports to the tax authority which transactions it had with related parties and with whom, without necessarily including the full technical analysis. In Colombia that form is Form 120; in Mexico, the informative duty is met inside the annual return, with the related party transaction detail Mexico's SAT requires.
Preparing this documentation requires inputs a group has to gather throughout the year, not at year end: intercompany contracts, financial statements for each entity, and a dated record of every payment's amount and counterparty. Without that ongoing record, the transfer pricing study becomes a late, more expensive reconstruction in the weeks before the deadline.
Related party payments in stablecoin: what changes and what does not
A related party payment made in USDC or USDT does not change the nature of the transaction or the transfer pricing obligation. It remains a payment between an entity and its parent, subsidiary, or affiliate, and it still requires that the agreed price or margin meet the arm's length principle. The currency or instrument used to move the value is not a factor either Article 260-2 of Colombia's Tax Code or Article 179 of Mexico's Income Tax Law considers when determining whether a related party relationship exists.
What does require an extra step is conversion: to document and file the transaction, the entity must translate the stablecoin amount into each country's functional currency at the official rate on the day of the transaction. In Colombia that reference is the Tasa Representativa del Mercado; in Mexico, the exchange rate Banco de México publishes, the same reference we cover in our guide on receiving international payments in USDC in Mexico.
Does an intercompany payment in stablecoin need a different transfer pricing analysis than one made in local currency?
An intercompany payment in stablecoin does not need a different analysis than one made in Colombian pesos, Mexican pesos, or US dollars: the arm's length analysis looks at the economic substance of the transaction, not the payment instrument. The entity still has to justify why the agreed price or margin matches what two independent parties would have used, whether the transfer moved by bank wire or by OTC stablecoin conversion.
What Soulbit delivers around transfer pricing and what it does not
Soulbit does not calculate the arm's length price of a related party transaction, does not select the applicable OECD method, and does not prepare or file supporting documentation or an informative return with DIAN or Mexico's SAT. That work requires a functional and economic analysis that belongs to a tax advisor or a transfer pricing specialist, never to the platform executing the payment.
What Soulbit provides today is traceability for related party payments: institutional custody with MPC technology over USDC and USDT balances, OTC conversion on request toward local currency, and a record by beneficiary and by batch of every transfer, with date, amount, and counterparty. That record is an input for the transfer pricing study a group must commission from its advisor, never a substitute for it.
| Transfer pricing task | Does Soulbit handle it today? | Who is responsible |
|---|---|---|
| Determine whether a transaction triggers the obligation | No | The entity and its tax advisor |
| Select the OECD method and calculate the arm's length range | No | The transfer pricing specialist |
| Record date, amount, and counterparty for each intercompany payment | Yes, through the record by beneficiary and by batch | Soulbit provides the record, the entity retains it |
| Convert a stablecoin payment into functional currency | Partial, through the transaction's OTC quote | The entity, backed by the quote |
| File Form 120 or Mexico's related party disclosure | No | The entity, as the direct filer |
Frequently asked questions
What counts as a related party for transfer pricing purposes?
A related party is a parent company, a subsidiary, or any entity in the same corporate group with which there is control, a relevant equity stake, or shared management. The relationship depends on corporate ties, not on where each entity is located. A supplier with no equity, control, or management link to the paying company is not a related party, even when the payment crosses a border.
What thresholds trigger the transfer pricing obligation in Colombia?
A Colombian entity is subject to transfer pricing rules when its gross assets exceed 100,000 UVT or its gross income exceeds 61,000 UVT at year end, and it had transactions with related parties abroad. With the 2026 UVT set at COP 52,374, those thresholds equal roughly COP 5,237 million in gross assets or COP 3,195 million in gross income. If the counterparty sits in a tax haven, the documentation duty applies regardless of amount.
What thresholds trigger the transfer pricing obligation in Mexico?
A Mexican entity carrying out business activities must keep transfer pricing documentation once its accumulated income in the prior fiscal year exceeded MXN 13 million, under Article 76 of the Income Tax Law. The threshold drops to MXN 3 million when the income comes from professional services. Both thresholds apply independently of one another.
Does paying a subsidiary in stablecoin change the transfer pricing obligation?
A payment to a subsidiary in USDC or USDT does not change the transfer pricing obligation: it remains a related party payment that must satisfy the arm's length principle. The only extra step is converting the stablecoin amount into each country's functional currency at the official rate on the day of the transaction, for documentation and filing purposes.
What is the arm's length principle and which methods does the OECD recognize?
The arm's length principle requires that a transaction between related parties be priced the way two independent parties would have priced a comparable transaction. The OECD guidelines recognize five methods to test that: comparable uncontrolled price, resale price, cost plus, transactional net margin, and profit split. A group must pick the method that fits the transaction, not the one that produces the lowest tax result.
