CRS Reporting for Escrow Accounts: Who Bears the Obligation?

In 2026, over 110 jurisdictions have committed to the automatic exchange of financial account information under the Common Reporting Standard (CRS), with the OECD reporting that more than €11 trillion in assets have been disclosed through this framework since its inception. For transactional lawyers and compliance officers navigating cross-border deals, one persistent ambiguity remains: the CRS classification and reporting obligations attached to escrow accounts. The determination of who bears the reporting obligation—whether the escrow agent, the bank holding the account, or the transaction parties—can significantly impact deal structuring and regulatory exposure.

Understanding the CRS Framework for Escrow Arrangements

The Common Reporting Standard, developed by the OECD and endorsed by the G20, requires Financial Institutions (FIs) to identify, document, and report financial accounts held by tax residents of participating jurisdictions. Escrow accounts, by their nature, present classification challenges because they involve three-party relationships: the payer, the payee, and the escrow agent. Under CRS, the fundamental question is whether the escrow account constitutes a Financial Account and, if so, which entity qualifies as the Reporting Financial Institution.

The CRS Commentary distinguishes between Custodial Institutions and Depository Institutions, each carrying different reporting responsibilities. An escrow account held with a bank typically falls under the definition of a Depository Account, making the bank the Reporting FI. However, where the escrow agent independently maintains the account as part of its business, the agent itself may qualify as a Custodial Institution or Depository Institution, depending on the specific facts. The OECD’s 2026 implementation guidance emphasizes that substance over form governs this analysis, meaning the actual functions performed by each party determine the classification.

Depository Institution vs. Custodial Institution: The Escrow Distinction

The classification of an escrow account under CRS hinges on whether the account is maintained by a Depository Institution or a Custodial Institution. A Depository Institution accepts deposits in the ordinary course of banking or similar business. When an escrow account is opened at a licensed bank, that bank is the Depository Institution, and the account constitutes a Depository Account. The bank bears the primary CRS reporting obligation, subject to due diligence requirements to identify the Account Holder.

However, the escrow agent CRS analysis becomes more complex when the agent itself holds client funds in a segregated client account at a bank. In this scenario, the escrow agent may be classified as a Custodial Institution if it holds Financial Assets for the benefit of others as a substantial portion of its business. The CRS defines Financial Assets broadly to include cash held in escrow pending transaction completion. Where the escrow agent qualifies as a Custodial Institution, it must treat the underlying beneficial owners—the transaction parties—as Account Holders and report accordingly. The 2026 OECD FAQ on escrow arrangements clarifies that passive escrow agents who merely hold funds without discretion may not reach the Custodial Institution threshold, shifting the obligation back to the bank.

Who Is the Account Holder? Determining the Reportable Person

Identifying the Account Holder for an escrow account is perhaps the most consequential determination in the CRS reporting chain. Under CRS, the Account Holder is the person listed or identified as the holder of the Financial Account by the Financial Institution that maintains the account. For escrow accounts, this determination depends on the legal and contractual framework governing the arrangement.

Where the escrow account is opened in the name of the escrow agent as principal, the agent is the Account Holder from the bank’s perspective. If the agent is not itself a Reporting FI, the bank must treat the agent as the Account Holder and apply CRS due diligence to the agent. However, the CRS contains a look-through requirement for certain entities: if the escrow agent is a Passive Non-Financial Entity (Passive NFE), the bank must identify the controlling persons behind the agent, which may include the transaction beneficiaries. Conversely, where the escrow account is structured as a joint account in the names of the transaction parties with the escrow agent as a signatory, the parties themselves are the Account Holders, and the bank reports directly on them.

Escrow Agent as Reporting Financial Institution: Triggering Events

An escrow agent may become the Reporting Financial Institution when it meets the definition of a Custodial Institution or Depository Institution in its own right. The key test is whether the agent holds Financial Assets for the account of others as a substantial portion of its business. The OECD has indicated that “substantial portion” is measured by reference to the entity’s gross income or the assets managed. Where 20% or more of the agent’s gross income derives from holding Financial Assets for others, or where 20% or more of the entity’s assets relate to such activities, the Custodial Institution classification is triggered.

For law firms and professional escrow agents that routinely handle third-party account CRS reporting, this threshold is easily crossed. In such cases, the escrow agent must register with its local tax authority as a Reporting FI, obtain a Global Intermediary Identification Number (GIIN) if also subject to FATCA, and implement CRS due diligence procedures. The agent must then determine whether the transaction parties are Reportable Persons—tax residents of CRS-participating jurisdictions—and report the account balance, gross proceeds, and other required information to its home tax authority for exchange. The 2026 CRS Implementation Handbook notes that professional escrow agents in major financial centers are increasingly being classified as Custodial Institutions, reflecting the professionalization of escrow services.

Cross-Border Escrow Accounts: Multi-Jurisdictional Reporting Challenges

Cross-border transactions introduce multi-jurisdictional complexity to CRS escrow reporting. Consider a typical M&A escrow: a buyer resident in Country A, a seller resident in Country B, an escrow agent located in Country C, and the escrow account held at a bank in Country D. Each jurisdiction may have its own CRS regulations and guidance, and the interplay between multiple reporting obligations can create both duplication and gaps.

The OECD’s 2026 updated CRS Commentary addresses this scenario through the hierarchy of reporting obligations. Where multiple FIs have reporting obligations with respect to the same account, the CRS generally assigns primary responsibility to the FI that maintains the account directly—typically the bank. However, where the escrow agent is itself a Custodial Institution, it must report on the underlying beneficiaries regardless of whether the bank also reports. To avoid double reporting, jurisdictions may adopt rules that permit one FI to rely on another’s reporting where certain conditions are met. Practitioners should carefully review the competent authority agreements between the relevant jurisdictions to determine whether such relief is available. In the absence of coordination, both the bank and the escrow agent may independently report, potentially triggering tax authority inquiries from the transaction parties.

Practical Compliance Steps for Escrow Agents and Transaction Parties

For escrow agents facing CRS obligations, proactive compliance is essential. The first step is to conduct a classification analysis to determine whether the agent qualifies as a Custodial Institution or Depository Institution. This analysis should be documented and reviewed annually, as changes in business volume or service offerings may alter the classification. If classified as a Reporting FI, the agent must register with its home tax authority, implement written CRS policies and procedures, and conduct due diligence on all escrow accounts opened after the applicable effective date.

Transaction parties should also be aware of the CRS implications of escrow arrangements. When negotiating transaction documents, parties should specify the CRS classification intended for the escrow account and allocate responsibility for any resulting tax reporting. In some cases, parties may wish to structure the escrow to achieve a particular CRS outcome—for example, by ensuring the account is treated as a Depository Account at a bank rather than a Custodial Account with the agent. Parties should also confirm the tax residency certifications provided to the escrow agent or bank are accurate, as misrepresentations can lead to penalties and, in some jurisdictions, criminal liability.

FAQ

Does an escrow account always trigger CRS reporting obligations?

No. An escrow account triggers CRS reporting only if it constitutes a Financial Account maintained by a Reporting Financial Institution in a CRS-participating jurisdiction, and if the Account Holder is a Reportable Person. If the escrow account is held at a bank in a non-CRS jurisdiction, or if the Account Holder is not a tax resident of a CRS-participating jurisdiction, no reporting obligation arises. However, as of 2026, with over 110 jurisdictions participating, the likelihood of no reporting is diminishing. Additionally, pre-existing accounts opened before the applicable CRS effective date may be subject to different due diligence rules, potentially deferring reporting.

Who is considered the Account Holder when an escrow agent opens an account at a bank?

The answer depends on how the account is structured. If the escrow agent opens the account in its own name as principal, the agent is the Account Holder from the bank’s perspective. The bank must then determine whether the agent is a Financial Institution or an Active or Passive NFE. If the agent is a Passive NFE, the bank must look through to the controlling persons, which may include the transaction parties. If the account is opened as a joint account naming the transaction parties with the agent as a signatory, the transaction parties are the Account Holders, and the bank reports directly on them. The 2026 OECD guidance encourages banks to review the underlying escrow agreement to correctly identify the Account Holder.

Can an escrow agent be classified as a Custodial Institution under CRS?

Yes, an escrow agent can be classified as a Custodial Institution if it holds Financial Assets for the account of others as a substantial portion of its business. The OECD considers 20% of gross income or assets as indicative of substantiality. A professional escrow agent that holds client funds in segregated accounts pending transaction completion is likely to meet this threshold. Law firms and trust companies that routinely provide escrow services should carefully assess their classification. If classified as a Custodial Institution, the agent must register as a Reporting FI and report on the underlying beneficial owners if they are Reportable Persons.

What information must be reported for an escrow account under CRS?

For a reportable escrow account, the Reporting FI must report: the name, address, jurisdiction(s) of tax residence, and Taxpayer Identification Number(s) of each Reportable Person; the account number or functional equivalent; the name and identifying number of the Reporting FI; the account balance or value as of the end of the reporting period; and, for Custodial Accounts, the total gross amount of interest, dividends, and other income credited to the account. For escrow accounts that are Depository Accounts, the total gross amount of interest credited is reported. The reporting is made annually to the FI’s home tax authority, which exchanges the information with the partner jurisdiction by September of the following year.
