The agreement supports the international exchange of tax information relating to large multinational enterprise groups under the Global Anti-Base Erosion framework.

According to Thailand’s Revenue Department, the Cabinet approved Thailand’s participation in the GloBE MCAA on 16 June 2026, and Thailand was subsequently officially listed by the OECD as a signatory on 8 September 2026.

For multinational groups operating in Thailand, this development is particularly important because it forms part of Thailand’s preparation for the international exchange of the GloBE Information Return (GIR).

What Is the GloBE MCAA?

The GloBE MCAA is a multilateral arrangement designed to enable participating tax authorities to exchange information contained in GloBE Information Returns.

The objective is to support international tax administration while reducing unnecessary duplication for multinational groups operating across several jurisdictions.

Rather than requiring the same set of information to be separately submitted to multiple participating jurisdictions, an information-exchange mechanism can allow relevant tax authorities to receive the required information through agreed international channels.

Thailand’s Revenue Department stated that this mechanism is intended to help reduce compliance burdens for large multinational groups while improving transparency and confidence in Thailand’s tax system.

Why Thailand’s Participation Matters

Thailand’s participation reflects the country’s continued integration into international tax cooperation frameworks.

For multinational companies, this means that international tax reporting can no longer be viewed solely as a matter for the head office or parent company.

Thai subsidiaries, branches and related entities within multinational groups should increasingly ensure that their accounting information, tax records and intercompany documentation are consistent with information reported elsewhere within the group.

Key areas that may require attention include:

• Consistency of financial and tax information across jurisdictions
• Identification of group entities and reporting responsibilities
• Reconciliation between statutory accounts and group reporting packages
• Documentation of related-party transactions
• Internal coordination between finance, tax and accounting teams
• Readiness to respond to information requests from tax authorities

GloBE Information Return and Thailand

A key part of the new framework is the GloBE Information Return, or GIR.

The Revenue Department confirmed that Thailand is preparing to exchange GIR information with treaty partners and expects its first exchange to take place by December 2027.

Businesses therefore have time to prepare, but multinational groups should not wait until the first exchange deadline before reviewing their internal systems.

Information used for international tax reporting often originates from accounting records created months or years earlier. Errors in entity classification, accounting treatment or intercompany transactions may become difficult to correct later.

What Multinational Companies in Thailand Should Do

Companies that form part of multinational groups should consider conducting an early review of their Thailand operations.

The review should include the company’s accounting system, corporate income tax records, financial statements and supporting documentation.

Management should also determine which company within the group is responsible for preparing the GloBE Information Return and how information from Thailand will be supplied to that company.

Where a Thai company receives instructions or reporting templates from an overseas parent company, the local accounting team should understand how those figures reconcile with the company’s Thai statutory accounts.

Accounting Records Will Become Increasingly Important

International tax transparency ultimately depends on the quality of underlying accounting information.

For companies in Thailand, accurate bookkeeping therefore remains fundamental.

Proper accounting records support not only annual financial statements and Thai tax filings, but also group-level reporting, tax reconciliations and cross-border information exchange.

Businesses should maintain complete documentation for material transactions and ensure that accounting records can be reconciled with tax filings and audited financial statements.

Preparing Before 2027

Thailand’s planned first exchange of GIR information by December 2027 provides multinational groups with an opportunity to prepare in advance.

Companies may consider reviewing the following areas:

Accounting Records

Check whether transactions are properly recorded, classified and supported by appropriate documentation.

Tax Compliance

Review whether corporate income tax, withholding tax and VAT records reconcile with the accounting system.

Group Reporting

Ensure that figures reported from Thailand are consistent with information submitted to overseas headquarters.

Intercompany Transactions

Review whether transactions with related companies are properly documented.

Internal Responsibility

Identify which person or department will coordinate GloBE-related information in Thailand.

Early preparation can reduce the risk of inconsistencies when information begins to be exchanged internationally.

Professional Accounting and Tax Support in Thailand

International businesses often need local accounting records to meet both Thai statutory requirements and group-level reporting requirements.

For multinational companies, proper coordination between local accounting records and international reporting requirements can become increasingly important as Thailand moves toward GloBE information exchange.

On 21 July 2026, the Thai Cabinet approved in principle a draft Royal Decree to amend and improve existing tax incentives for Social Enterprises.

The proposed measures aim to provide broader and more continuous support for Social Enterprises, recognising their role in addressing social challenges and contributing to Thailand’s progress toward the United Nations Sustainable Development Goals (SDGs).

What is a Social Enterprise?

A Social Enterprise is generally a business that conducts commercial activities while pursuing social, community or environmental objectives.

Thailand has introduced tax incentives to encourage individuals, companies and investors to support qualifying Social Enterprises and the Social Enterprise Promotion Fund.

The latest proposal seeks to expand those incentives further.

5 Key Proposed Tax Measures for Social Enterprises in Thailand

1. Companies supporting Social Enterprises may claim a one-times expense deduction without an expiry date

Under the previous measure, a company or juristic partnership providing money or property to support a Social Enterprise could claim a tax expense deduction equal to one times the qualifying amount, with the incentive previously scheduled to expire on 31 December 2023.

Under the proposed amendment, the government would extend this incentive without a specified expiry date.

This may provide greater certainty for businesses wishing to support Social Enterprises as part of their long-term social, CSR or ESG initiatives, subject to applicable tax requirements.

2. Individual taxpayers may claim a one-times tax deduction

The proposed measures introduce an additional incentive for individual taxpayers who provide financial support to qualifying Social Enterprises.

Eligible financial contributions would be deductible at one times the qualifying amount, with no specified expiry date.

The actual availability and amount of any tax deduction remain subject to the conditions and limitations prescribed by Thai tax law.

3. Double tax deduction for donations to the Social Enterprise Promotion Fund

One of the most significant proposed incentives concerns donations of money or property to the Social Enterprise Promotion Fund.

The deduction would increase from one times to two times the qualifying donation.

The enhanced incentive would apply to qualifying donations made between:

1 January 2024 and 31 December 2028.

Taxpayers must nevertheless comply with all applicable statutory requirements and conditions.

e-Donation Requirement

The proposed measures require taxpayers to make qualifying support and donations through the Thai Revenue Department’s electronic donation system (e-Donation).

Companies and individuals intending to claim these tax benefits should therefore confirm that the relevant recipient, Social Enterprise or fund qualifies under the Revenue Department’s requirements and ensure that the transaction appears correctly in the e-Donation system.

4. Extension of tax exemptions for transfers and donations of property

The draft measure also proposes extending tax exemptions for individuals, companies and juristic partnerships that transfer property to qualifying Social Enterprises or donate property to the Social Enterprise Promotion Fund through the e-Donation system.

The proposed exemptions cover several types of Thai taxation, including:

• Personal Income Tax
• Corporate Income Tax
• Value Added Tax (VAT)
• Specific Business Tax
• Stamp Duty

These exemptions previously applied until 31 December 2023. The proposal would extend them without a specified expiry date.

5. More flexible registration for Social Enterprise tax incentives

The proposed amendment also seeks to relax the registration requirements applicable to Social Enterprises wishing to obtain tax incentives.

A Social Enterprise that misses the original statutory notification deadline may still register later.

However, if a Social Enterprise registers after the prescribed deadline, its tax incentives and those available to its supporters would generally commence from the accounting period or tax year following the period or year in which it submits the notification.

Investors may only need to hold their investment for 10 years

The Revenue Department has also indicated that, once the new Royal Decree comes into force, it expects to amend Revenue Department Director-General Notification No. 38.

The proposed change relates to tax deductions for investments in shares or partnership interests made for the establishment or capital increase of a Social Enterprise.

Under the proposed rule, an investor would need to retain the relevant shares or partnership interest for at least 10 years from the investment date.

This would replace the existing rule requiring investors to retain the investment indefinitely.

According to the Revenue Department announcement, the revised rule should also cover earlier investments that predate the new Royal Decree.

Who should monitor these changes?

The proposed measures are particularly relevant to several groups.

Social Enterprises

Social Enterprises should review their registration status, tax-incentive notification requirements and ability to participate in the Revenue Department’s e-Donation system.

Thai Companies and Juristic Partnerships

Businesses undertaking CSR, ESG or other social-support programmes should assess whether qualifying contributions could benefit from available tax deductions.

Individual Taxpayers

Individuals financially supporting qualifying Social Enterprises may become entitled to additional personal income tax deductions, subject to statutory conditions.

Investors

The proposed 10-year holding requirement may provide greater flexibility for investors considering investments in Social Enterprises.

Important: Cabinet Approval in Principle Does Not Yet Make the Measures Fully Effective Law

The Revenue Department’s announcement dated 21 July 2026 states that the Cabinet approved in principle a draft Royal Decree.

Accordingly, taxpayers should not assume that they can immediately apply every proposed measure to a tax return or transaction without first checking the final legislation and its effective date.

Before claiming a tax incentive, taxpayers should verify, among other matters:

• whether the new Royal Decree has entered into force;
• the applicable effective date;
• whether both the contributor and recipient satisfy the prescribed conditions;
• whether the transaction appears correctly in the e-Donation system;
• whether any statutory deduction limits or other tax conditions apply.

Conclusion

Overall, the proposed Thailand Social Enterprise Tax Incentives could provide broader tax benefits for companies, individuals, donors and investors supporting qualifying Social Enterprises. Thailand’s proposed Social Enterprise tax measures represent a significant expansion of tax incentives available to businesses, individuals, donors and investors supporting socially responsible enterprises.

Key proposals include continuing one-times deductions for corporate supporters, introducing deductions for individual supporters, providing double deductions for qualifying donations to the Social Enterprise Promotion Fund, extending certain tax exemptions and relaxing investment and registration requirements.

Businesses and taxpayers intending to rely on these incentives should continue to monitor the final Royal Decree, Revenue Department notifications and related implementation rules before claiming the relevant tax benefits.
