In Thailand's real estate and M&A market, it is common for investors to acquire shares in a property-holding company rather than purchasing the underlying land directly. From a commercial perspective, such structures may offer advantages in terms of transaction efficiency, continuity of licenses, contractual relationships, and operational infrastructure. However, where the target company's primary asset is real estate, the distinction between a share acquisition and a property transfer can become increasingly blurred from a tax and regulatory perspective.
As Thailand's enforcement landscape continues to evolve, investors, corporate advisors, and legal practitioners must carefully consider whether a transaction's legal form accurately reflects its commercial substance. While a share sale remains legally distinct from a direct transfer of land, transactions involving land-rich companies may attract heightened scrutiny where the economic reality suggests that the true object of the acquisition is the underlying real estate itself.
This issue has become particularly relevant in acquisitions involving special purpose vehicles, dormant companies holding valuable land assets, hospitality projects, development sites, and other structures where the target company's value is overwhelmingly derived from immovable property rather than an active operating business.
The Substance-Over-Form Challenge
Thailand's tax framework has increasingly reflected a broader international trend toward examining the substance of transactions rather than relying exclusively on their legal characterization. Tax authorities are generally entitled to consider the commercial reality of an arrangement when assessing whether a particular structure has been implemented primarily to achieve a tax result that differs from the economic outcome of the transaction.
In the context of real estate acquisitions, this principle creates a potential area of concern where a purchaser acquires all or substantially all of the shares in a company whose principal asset consists of land or property. Although ownership of the land remains legally vested in the company, the practical effect of the transaction may be that control over the underlying real estate has changed hands entirely.
The issue becomes more pronounced where the target company has little independent business activity, limited operational substance, or exists primarily as a vehicle for holding a specific property asset. In such circumstances, tax authorities may be inclined to examine whether the transaction represents a genuine corporate acquisition or merely an indirect mechanism for transferring beneficial ownership of real estate.
While every transaction must be assessed on its own facts and circumstances, the growing focus on beneficial ownership, nominee arrangements, and land-holding structures has significantly increased the importance of careful transaction planning.
Specific Business Tax Exposure: A Risk That Often Emerges After Closing
One of the most significant concerns arising from this analysis is the potential application of Specific Business Tax ("SBT"). Under Thailand's Revenue Code, certain sales of immovable property conducted in a commercial or profit-making manner are subject to SBT at an effective rate of 3.3%, inclusive of municipal tax.
Traditionally, SBT is associated with direct transfers of real estate and is accounted for as part of the land transfer process. However, in transactions involving property-rich companies, investors often focus exclusively on the mechanics of the share acquisition and may overlook the possibility that tax authorities could later scrutinize the transaction from a broader economic perspective.
The commercial risk is compounded by the fact that any challenge by the Revenue Department is unlikely to arise at closing. Instead, a review may occur months or even years after the transaction has been completed. By that stage, the purchase price has been fully paid, the seller may no longer have a meaningful presence in Thailand, and the buyer may be left to manage the consequences of a tax dispute that originated from the acquisition structure itself.
In addition to the underlying tax assessment, exposure may extend to surcharges, penalties, interest, professional costs, and significant management time spent responding to inquiries or defending assessments. For large-scale property transactions, the financial impact can be substantial and may materially affect the overall economics of the investment.
Why Traditional Due Diligence May Not Be Sufficient
Many investors assume that a comprehensive tax due diligence exercise will adequately protect them against post-closing liabilities. While due diligence remains an essential component of any acquisition process, it is important to recognize its limitations.
Conventional due diligence is designed primarily to identify historical liabilities and compliance issues that exist within the target company prior to closing. The potential risk arising from a future recharacterization of the acquisition structure is fundamentally different. It is not necessarily a historical issue embedded within the company; rather, it is a risk created by the transaction itself and the manner in which it has been structured.
As a result, buyers should approach property-holding company acquisitions through a broader risk-management lens. This requires a coordinated assessment involving legal, tax, corporate, and regulatory considerations. Particular attention should be given to the operational substance of the target company, the commercial rationale supporting the transaction structure, the historical use of the company, and the extent to which the company conducts genuine business activities independent of its property holdings.
The objective is not merely to identify risks, but to determine how those risks should be allocated between the parties.
The Critical Importance of Robust Tax Indemnities
Given the uncertainty that can accompany future tax assessments, the Share Purchase Agreement ("SPA") becomes one of the most important tools for protecting a buyer's position.
In many transactions, parties rely on standard tax warranties that confirm compliance with applicable tax laws. Although such warranties provide a degree of protection, they are often insufficient when dealing with potential SBT exposure arising from the transaction itself. The buyer's concern is not necessarily whether the company complied with its historical tax obligations, but whether the Revenue Department may subsequently challenge the structure adopted by the parties.
For this reason, sophisticated transactions increasingly include bespoke tax indemnity provisions specifically addressing any tax liabilities that arise as a consequence of the acquisition. Such indemnities should be carefully drafted to cover not only the underlying tax assessment but also related interest, penalties, surcharges, professional fees, and dispute resolution costs.
Equally important is the practical enforceability of the indemnity. A contractual right has little value if the seller lacks the financial resources to satisfy a future claim. Accordingly, buyers often negotiate escrow arrangements, retention mechanisms, or deferred consideration structures to ensure that meaningful recourse remains available should a post-closing assessment occur.
In transactions involving high-value land assets, these protections should be viewed not as aggressive negotiation tactics but as prudent risk allocation mechanisms.
Thailand remains an attractive destination for real estate investment, and acquisitions of property-holding companies continue to play an important role in sophisticated transaction structures. Nevertheless, investors should recognize that regulatory authorities are increasingly focused on the economic substance of transactions, particularly where valuable real estate assets are involved.
The assumption that a share acquisition automatically eliminates risks associated with a direct property transfer is no longer a safe one. Where a transaction effectively transfers control of a land-rich enterprise, buyers must carefully evaluate the possibility of future tax scrutiny and ensure that appropriate contractual protections are in place.
Ultimately, successful acquisition planning requires more than technical compliance. It requires a thorough understanding of how tax authorities may interpret the commercial realities underlying a transaction. In the current enforcement environment, robust due diligence, thoughtful structuring, and carefully drafted tax indemnities are not merely legal safeguards—they are essential components of prudent investment risk management.
