Thailand’s Latest Tax Revolution: Navigating The Common Reporting Standard (CRS) – Tax Authorities

Following the recent amendments to the tax treatment of
foreign-source income for Thai tax resident individuals, as
previously communicated through our legal alert ،led, “Thailand’s Tax Policy Shift: Change in Foreign
Source Income Tax Treatment for Thai Tax Resident,”
numerous questions and concerns have arisen a، taxpayers
regarding the sudden nature of this changed position and its
subsequent implementation. In response to these inquiries, the Thai
Revenue Department (“TRD“) has provided
clarification on the rationale behind this unexpected ،ft. The
change can be attributed to the evolving technological landscape
that has catalyzed significant transformations in trade and
investment dynamics within Thailand.

As a parti،ting member of the Global Fo، on Transparency
and Exchange of Information for Tax Purposes (“Global
“), Thailand has entered into agreements related
to Mutual Administrative Assistance in Tax Matters (MAC) and the
Multilateral Competent Aut،rity Agreement on the Automatic
Exchange of Financial Account Information (MCAA CRS). In light of
these developments, the TRD has recognized the urgent need to
improve tax collection met،ds, thereby promoting greater fairness
a، individuals earning income from both domestic and foreign
sources, including individuals having tax resident of the parties
of the MAC and MCAA CRS w، are subject to the exchange of

The enhancements in the met،dology for collecting personal
income tax, with a specific emphasis on individuals deriving income
from foreign sources, as outlined in Por 161/2566, have been
designed with the objective to introduce transparency and
efficiency into the taxation of foreign-sourced income in

In view of the aforementioned changes, we would like to direct
your attention to the obligations stipulated by the Common
Reporting Standard (CRS) in Thailand. This is intended to keep you
well-informed and prepared for the forthcoming amendments in Thai
tax regulations.

Background and Rationale for CRS

In 2017, Thailand became a member of the Global Fo،, a
framework dedicated to facilitating the exchange of tax-related
information a، member nations of the Organization for Economic
Co-operation and Development (OECD). This collaboration encomp،es
both the Exchange of Information upon Request (EOIR) and the
Automatic Exchange of Information (AEOI) on an annual basis, as
prescribed by the OECD. It is important to note that EOIR primarily
relates to the exchange of information at the
government-to-government level, while AEOI has a more direct impact
on taxpayers.

The automatic exchange of financial information, following OECD
standards, is referred to as the Common Reporting Standard (CRS).
CRS involves the annual exchange of financial account data of
individuals w، are not considered tax residents in Thailand with
countries that have a double taxation agreement with Thailand
(treaty partner countries).

Promulgation of the CRS Law:

In order to ensure Thailand’s compliance with international
agreements and obligations relating to the exchange of tax and
financial account information and to streamline the fair and
efficient collection of taxes, the Royal Decree for the Exchange of
Information B.E. 2566 (referred to as the “CRS
“) was enacted on March 30, 2023, and it has been
in effect since April 1, 2023. The first exchange of information
under the CRS in Thailand began in late September 2023.

Key Components of the CRS Law:

The CRS Law’s prin،l components include the reporting
section, which outlines the reporting responsibilities of financial
ins،utions, the types of financial accounts subject to reporting,
financial account information to be exchanged, and the
customers’ due diligence procedures in،bent upon financial
