The international exchange of information between governments will be extended to immovable property.

OECD Establish Framework for Automatic Exchange of Information on Immovable Property

Last week, twenty-six jurisdictions pledged to implement the new OECD framework for the automatic exchange of information on offshore real estate, marking an expansion of global tax transparency beyond financial accounts and crypto-assets. The initiative is set out in the Multilateral Competent Authority Agreement on the Exchange of Readily Available Information on Immovable Property (IPI MCAA), designed to close long-standing gaps in cross-border tax reporting by enabling tax administrations to access electronically searchable and reliable data on foreign property holdings, transactions and related income. The framework responds to challenges faced by administrations, including limited visibility over cross-border immovable property ownership, rising levels of underreported foreign property and the use of real estate to shelter undeclared wealth.

There is a joint statement published by the OECD with the following text:

In recent years, tax policy developments have greatly enhanced cross-border exchanges of tax information and international cooperation between tax administrations, combating offshore tax non-compliance and tax secrecy on financial accounts. This includes delivering transparency through automatic exchange of financial assets (through the Common Reporting Standard) and crypto-assets (through the Crypto-Asset Reporting Framework).

Despite these significant advances in automatic exchange of information, there is not yet a mechanism for jurisdictions to exchange information on non-financial assets, especially immovable property.

Recognising that ownership and transactions involving immovable property often have cross-border elements, we acknowledge the need for improved mechanisms to ensure that tax authorities have access to relevant information on immovable property assets held and income derived therefrom abroad to enforce tax laws effectively. We therefore welcome the new Multilateral Competent Authority Agreement on Automatic Exchange of Readily Available Information on Immovable Property (IPI MCAA) between tax authorities developed by the OECD.

The broad adoption of the IPI MCAA is an important step towards delivering tax transparency on non-financial assets. It will strengthen our ability to monitor and enforce tax compliance, and to combat tax evasion, which undermines public revenues and unfairly shifts the tax burden onto compliant taxpayers.

We aim to join the IPI MCAA by 2029 or 2030, subject to domestic procedures as applicable.

We also encourage other jurisdictions to join this initiative in the collective effort to promote transparency, fairness and efficiency in global taxation.
