The new era of international taxation encourages multinational investors to place tax readiness as an integral part of investment strategy and corporate governance. In an increasingly transparent global business environment, taxation is no longer viewed merely as a compliance obligation, but also as a critical element in risk management, decision-making, and investment sustainability. This article discusses the readiness checklist that investors should consider in addressing the implementation of Pillar Two and the Global Minimum Tax, covering the assessment of regulatory scope, evaluation of Effective Tax Rate (ETR), review of tax incentives, alignment of Transfer Pricing Documentation with GloBE data, data readiness, and the strengthening of tax governance frameworks. Companies must ensure that their tax positions are not only accurate from a calculation perspective, but also supported by reliable data, sufficient business substance, and transparent and accountable decision-making processes. With tax advisors playing an increasingly strategic role as business partners, early preparation becomes a critical factor in helping investors manage top-up tax risks, enhance certainty, and build resilient investment structures with long-term credibility.
The previous four articles in this series have guided NIHAO readers through the fundamentals of Pillar Two, the technical framework of Indonesia’s Ministry of Finance Regulation (PMK) No. 136 of 2024, its relationship with Transfer Pricing Documentation, and the broader transition from tax planning toward tax governance. This fifth article moves into a more practical stage: what investors should assess before global minimum tax rules evolve into risks that are discovered too late. This readiness checklist is intended to help multinational investors identify where to begin in establishing tax governance in the era of Pillar Two and the Global Minimum Tax.
For investors, Pillar Two should not merely be viewed as a compliance obligation, but as an opportunity to build investments that are more predictable, better documented, and more resilient under regulatory scrutiny. In an increasingly transparent global tax environment, the companies best prepared will not simply be those capable of calculating tax liabilities, but those able to demonstrate that their tax positions are supported by data, commercial substance, and sound governance.
The first step is to assess whether the multinational group falls within the scope of Pillar Two. Under PMK No. 136 of 2024, the rules generally apply to Multinational Enterprise Groups with consolidated revenues of at least EUR750 million in at least two of the four preceding fiscal years. For investors, this assessment should be undertaken at the outset of an investment, acquisition, restructuring exercise, or cross-border expansion, not after the financial statements have already been finalized.
The second step is to map jurisdictions and effective tax rates (ETR). Investors should identify countries where the group’s ETR may fall below 15%, including Indonesia where tax incentives, fiscal losses, temporary differences, or certain related-party transaction structures may reduce the effective tax burden. This analysis is essential because top-up tax obligations may arise through the Income Inclusion Rule (IIR), Domestic Minimum Top-up Tax (DMTT), or Undertaxed Payments Rule (UTPR), depending on the group’s structure and the rules adopted in relevant jurisdictions.
The third step is to revisit the economic value of tax incentives. Tax holidays, tax allowances, super deductions, and special economic zone incentives may continue to provide meaningful benefits to investors. However, under Pillar Two, those benefits must be reassessed from an economic perspective rather than solely a domestic tax perspective. An incentive that reduces local tax costs may ultimately result in part of the benefit being absorbed through a top-up tax in another jurisdiction. Consequently, investors should no longer ask merely whether incentives are available; they should ask whether those incentives continue to generate a net economic benefit after considering Pillar Two implications.
The fourth step is to ensure alignment between Transfer Pricing Documentation (TP Documentation), Country-by-Country Reporting, financial statements, tax returns, and GloBE data. PMK No. 172 of 2023 remains a key foundation for the arm’s length principle, TP Documentation, Advance Pricing Agreements (APA), and Mutual Agreement Procedures (MAP). In practice, under Pillar Two, TP Documentation no longer serves solely as a defensive file for related-party transactions. Instead, it becomes part of a broader data ecosystem that explains why profits arise in particular jurisdictions and whether those profit allocations are supported by functions performed, assets employed, risks assumed, and genuine business substance.
The fifth step is data readiness. GloBE calculations require accounting and tax data that are often distributed across multiple business functions, including finance, accounting, tax, legal, human resources, treasury, ERP systems, and operational departments. Payroll information, tangible assets, deferred tax balances, covered taxes, ownership structures, intercompany charges, and tax incentives frequently originate from different sources. Without adequate data readiness, companies may understand the rules conceptually yet struggle to implement them operationally.
The sixth step is to establish a tax governance framework. Investors should ensure that internal policies clearly define who is responsible for the group’s tax position, who validates tax data, who approves tax positions, how tax matters are escalated to the Board, and when decisions should be brought to the attention of senior management or the audit committee. At this stage, Pillar Two transforms tax from an annual technical exercise into a core element of enterprise risk management.
The involvement of tax advisors becomes increasingly strategic because their role can no longer be limited to preparing tax returns or calculating tax liabilities. In the context of Pillar Two, tax advisors must act as navigators who connect regulations, investment structures, transfer pricing, financial data, tax incentives, governance frameworks, and communication with management. Their value lies not merely in performing calculations, but in helping investors understand the business implications of each tax decision.
For foreign investors entering Indonesia, tax advisors can assist with Pillar Two impact assessments, incentive reviews, transfer pricing alignment, DMTT analyses, and reporting readiness. For Indonesian businesses expanding overseas, advisors can support the design of holding structures, financing arrangements, royalty models, service fee mechanisms, and business substance that can withstand scrutiny from tax authorities across multiple jurisdictions. In other words, tax advisors become part of the architecture of investment certainty.
This role must, however, be exercised responsibly and with balance. Effective tax advisors do not encourage investors to oppose governments or pursue aggressive loopholes. Instead, they help investors understand regulations clearly, utilize legitimate incentives, avoid unnecessary risks, and establish tax positions that can be professionally explained and defended. Such an approach is pro-investor because it provides certainty, and pro-government because it strengthens the quality of tax compliance.
Investors increasingly require advisors who understand not only taxation, but also business operations, regulatory frameworks, governance expectations, and cross-border realities. SW Tax Consulting supports investors throughout the entire journey from assessment, training, structuring, and documentation to governance design and implementation coordination. In the Pillar Two era, the greatest value no longer lies in finding the lowest tax rate, but in building structures that are transparent, robust, and trusted.
Ultimately, the Pillar Two readiness checklist is a reflection of investment maturity. Companies focused solely on short-term efficiency may perceive these rules as a burden. Those with a long-term perspective will view them as an opportunity to strengthen trust and credibility. In an increasingly transparent global tax environment, certainty has become the new form of competitiveness.
Investor readiness checklist:
- Assess whether the group meets the EUR 750 million threshold and falls within Pillar Two scope.
- Map effective tax rates by jurisdiction and identify potential top-up tax exposure.
- Review tax incentives against DMTT, IIR, and UTPR implications.
- Align TP Documentation, CbCR, tax returns, financial statements, and GloBE data.
- Establish data readiness and a robust tax governance framework.
- Engage tax advisors early in the investment, acquisition, or restructuring process.
