Addressing the Elephant in the Room of Indonesia’s Tax Ratio

Written by Fatikha Faradina, Directorate General of Taxes' employee

For over a decade, the narrative surrounding Indonesia’s tax administration has been heavily anchored in one vital word which is integrity. Bureaucratic reform has been our North Star, guiding the Directorate General of Taxes (DJP) through a massive cultural transformation. Today, it is safe to say that this mission has achieved its primary goal. Integrity is no longer an aspiration, it is the absolute baseline. It is a value that should already be deeply embedded in the subconscious of every tax official.

We have successfully rebuilt public trust and fortified our internal ethics. But as we stand on this solid foundation, a compelling question arises, what is our next great frontier? If integrity is the established norm, it is time we shift our collective focus toward the ultimate output of our institution. It is time we address the elephant in the room: the stagnation of Indonesia’s tax ratio.

To truly understand the gravity of this stagnation, we only need to look across our borders. In the Asia-Pacific region, the average tax-to-GDP ratio sits near 19.6%. Even within our own ASEAN neighborhood, peers like the Philippines, Thailand, and Vietnam consistently capture between 16% and 18% of their economic output. Meanwhile, Indonesia’s ratio stubbornly lingers around the 10% to 12% mark, depending on whether we apply the narrow national definition or the broader OECD standard. This gap is not merely a statistical quirk, it is a glaring indicator of untaxed economic potential that we can no longer afford to ignore.

If we cast our gaze further toward mature economies, the contrast becomes even more profound and highlights the structural mountain we must climb. Consider Sweden, a nation where the tax ratio exceeds 41%. While their system reflects a radically different social contract, it perfectly demonstrates the revenue power of a highly formalized economy where nearly all individual economic activity is tracked and taxed. Even Switzerland, known for its decentralized system and efficient rather than punishing tax rates, maintains a ratio of over 27%, more than double ours.

These international benchmarks reveal a crucial truth, countries do not cross the 25% threshold simply by auditing large corporations. They achieve it through a massive, compliant base of individual taxpayers and formalized small businesses. Recognizing this points us directly toward the root causes of our own stagnation.

The Challenge of the "Missing Middle" and the Informal Economy

Our primary hurdle is the sheer size of Indonesia's informal sector. While our formal economy continues to grow and comply, a vast segment of economic activity remains in the shadows. We are missing the "middle" the millions of micro, small, and medium enterprises (MSMEs) that drive daily commerce but remain outside the tax net. The challenge is no longer just about auditing the non-compliant formal businesses, it is about strategically bringing this shadow economy into the light. This requires a paradigm shift from traditional enforcement to innovative policy design that lowers the cost of compliance while establishing clear, traceable economic footprints.

Narrow Tax Base vs. Generous Exemptions

We must also critically evaluate our tax base. Historical policy choices, including various exemptions, tax holidays, and high non-taxable income thresholds, have inadvertently narrowed the pool of active contributors. While these incentives were designed to stimulate specific sectors, we must continuously measure their actual economic multiplier against the opportunity cost of lost revenue. Optimizing the tax ratio means finding the delicate equilibrium between incentivizing investment and securing state revenue.

From Manual Oversight to Data-Driven Precision

As we transition into the era of the Core Tax Administration System (CTAS), our operational mindset must evolve. We are moving away from manual, localized oversight toward a borderless, data-driven ecosystem. The stagnation of the tax ratio can only be cured if we utilize third-party data and international tax information exchanges effectively. The future of revenue generation lies in predictive analytics, identifying revenue leakages before they occur and understanding complex, cross-border tax planning strategies utilized by multinational entities.

The New Paradigm for Tax Officials

For the modern tax official, the definition of excellence must evolve. Being honest and disciplined is the bare minimum. The new standard demands profound technical competence, an understanding of dynamic business models, and a strong grasp of macroeconomic indicators. We must transform from being mere administrators of the law into strategic partners in national economic development.

The reform of our institutional character was a necessary first chapter, and we have written it well. Now, we must write the next one. By confronting the stagnant tax ratio head-on through expanding the base, formalizing the informal sector, and leveraging advanced data analytics we can ensure that the integrity we fought so hard to build translates into the robust state revenue our nation deserves. The foundation is set, it is time to build the house.
