Understanding Ex Aequo Et Bono: How Indonesia Ensures Fair Tax Judgments
When tax disputes arise, many business owners hope that decisions will go beyond rigid legal wording and reflect a sense of fairness . This is where the principle of ex aequo et bono—Latin for “according to what is fair and good”—comes into play . In Indonesia’s tax system, this principle allows judges to consider justice and equity, not just technical compliance, when resolving complex tax cases.
According to the Directorate General of Taxes, fair interpretation plays a vital role in maintaining public trust during tax appeals and objection reviews . While regulations under the Ministry of Finance establish procedural limits, the Tax Court has discretion to apply ex aequo et bono in exceptional situations where strict application of the law would create an unjust outcome . This approach strengthens both taxpayer protection and government accountability—especially for PT PMA entities or multinational investors facing nuanced cases.
For instance, a Bali-based logistics company once faced double taxation after a reporting mismatch between two fiscal years. After presenting evidence and legal reasoning consistent with ex aequo et bono principles, the Tax Court partially granted their appeal . This example shows how fairness, backed by proper documentation and professional advocacy, can help businesses achieve balanced and transparent tax resolutions in Indonesia .

What Is Ex Aequo Et Bono in Indonesia’s Tax Court?
The Latin phrase ex aequo et bono means “according to what is fair and good.” In simple terms, it allows judges in Indonesia’s tax court to make decisions based on fairness rather than just rigid legal wording.
Imagine two companies filing similar tax reports — one makes a small technical mistake, and the other follows everything perfectly. Under ex aequo et bono, judges can recognize good faith effort and apply justice more humanely . This principle balances the letter of the law with its spirit, ensuring that justice doesn’t become robotic.
By using ex aequo et bono, Indonesia’s tax court promotes a culture of fair tax judgment where taxpayers and authorities both act responsibly . It keeps legal outcomes grounded in common sense and equity — two values that strengthen public trust in the system.

For PT PMA (foreign-owned companies) in Indonesia, fair tax judgment is not just a legal issue — it’s a matter of survival. When investment structures, invoices, or cross-border transactions are misinterpreted, the financial impact can be massive .
Ex aequo et bono offers a bridge between law and economic reality. It helps judges consider how a PT PMA operates globally and the intent behind each transaction. For example, if a company pays tax late due to currency transfer delays, judges can view it through a lens of equity .
This approach builds confidence among foreign investors who fear being trapped in bureaucratic complexities. By applying fair tax judgment, Indonesia shows that it values fair play and transparency . That trust encourages more responsible investments and supports the nation’s economic growth .
In practice, the Indonesia tax court does not use ex aequo et bono casually . It comes into play only when strict application of law creates unfair consequences.
Judges review evidence, intent, and the overall context of a case. If a company has acted transparently and in good faith, the court may decide based on fairness rather than technical faults.
For example, in some fair tax judgments, the court has reduced penalties for minor clerical errors or adjusted tax amounts when regulations were ambiguous. Such actions illustrate how justice in tax cases is not only about numbers but also about values.
Ultimately, the application of ex aequo et bono keeps Indonesia’s tax system flexible yet principled, protecting both state revenue and taxpayer rights .
Judges turn to ex aequo et bono when the law alone does not capture the whole truth . For instance, when two regulations conflict or a policy lacks clarity, fairness becomes the guiding light.
The Indonesia tax court often considers factors like honest intent, document transparency, and economic impact. A judge might think, “If we apply this law strictly, will it cause unfair hardship?” If yes, the principle is activated.
This human-centered interpretation ensures that fair tax judgment reflects the spirit of justice and not just its text. It also encourages taxpayers to cooperate openly with authorities rather than fear them .
By acknowledging good intent, judges strengthen public confidence and create a more trust-based tax culture.
Let’s break down a typical fair tax judgment using the principle of ex aequo et bono. A small import company in Jakarta under-reported its VAT by a few percent because its supplier submitted incomplete invoices . Technically, this was a violation.
However, the Indonesia tax court found that the company had kept all receipts and cooperated fully during audit . Since the mistake was administrative, not intentional, the judge reduced the penalty and allowed a re-submission of correct data.
This decision balanced fairness and discipline. It showed that while taxpayers must obey rules, the law should not punish honest errors. That’s the true value of ex aequo et bono — it turns a cold process into a human one.
The idea of ex aequo et bono comes from international law but fits well within Indonesia’s legal culture . It’s recognized under Law No. 14/2002 on the Tax Court and supported by the Ministry of Finance’s guidelines.
This principle requires judges to consider equity, ethics, and intent before reaching a decision. It also reflects Pancasila’s values of justice and humanity, which guide many Indonesian institutions .
When interpreted correctly, ex aequo et bono acts as a moral compass within the Indonesia tax court, ensuring every ruling supports social harmony and public trust . That’s why tax law in Indonesia is not just about compliance — it’s about balance and responsibility.
Meet Daniel Fischer, a German entrepreneur who runs a logistics company in Canggu, Bali . After expanding his PT PMA operations, he faced a massive tax bill due to a clerical error in reporting foreign transactions.
At first, he was devastated. The audit claimed he owed double taxes for two fiscal years . Daniel gathered receipts, bank records, and advice from his consultant at Bali Business Consulting. Together, they filed an appeal based on ex aequo et bono, arguing that the mismatch was technical, not fraudulent.
In court, his legal team demonstrated good faith and transparent documentation. The judge acknowledged that strict law application would lead to an unfair result . Applying fair tax judgment, the court reduced the penalty by 60% and cleared future audit flags .
