In Phnom Penh, Cambodia’s sweeping tax modernisation efforts are delivering remarkable results, with government tax revenue surging from $700 million in 2012 to more than $3.57 billion in 2025. The dramatic increase reflects the country’s expanding economy, stronger tax compliance, and rapid digital transformation within the General Department of Taxation. Officials say the reforms are helping Cambodia build a more transparent, efficient, and internationally competitive tax administration system capable of supporting long term national development goals.
The announcement was made during the inauguration ceremony of the new General Department of Taxation headquarters, known as the GDT Tower, attended by Prime Minister Hun Manet, senior government officials, and business leaders. The event highlighted how digital technology and institutional reforms are reshaping Cambodia’s public financial management system.

Digital Transformation Reshapes Cambodia’s Tax System
Kong Vibol, Minister Attached to the Prime Minister and Director General of Taxation, said Cambodia’s tax reforms have transformed the way revenue is collected and managed across the country. According to Vibol, the introduction of digital systems has improved service quality while strengthening taxpayer compliance and overall efficiency.
“The digital transformation has improved the quality of tax administration while supporting stronger revenue collection and greater compliance among taxpayers,” Vibol said.
He explained that the GDT has developed a broad digital ecosystem that allows taxpayers to complete obligations more easily while reducing administrative delays and inconsistencies that once affected the agency. The reforms have also increased the government’s fiscal capacity to fund infrastructure, public services, and national development priorities.
Cambodia’s tax collection system is currently divided between two major institutions. The General Department of Taxation manages domestic taxes including income tax, salary tax, value added tax, and property tax, while the General Department of Customs and Excise oversees customs duties and international trade related taxes.
Hun Manet Pushes for AI Driven Tax Reform
Speaking during the opening ceremony of the new GDT headquarters in Phnom Penh, Prime Minister Hun Manet called on tax authorities to continue accelerating reforms and embrace modern technologies, especially Artificial Intelligence and digital systems, to improve efficiency and align Cambodia with international standards.
“Reform is not easy. Reforming and implementing it effectively and consistently is even more difficult,” he said.
The Prime Minister stressed that meaningful progress requires governments to take risks and adapt to changing conditions, even when reforms may not guarantee immediate success.
“Even with careful planning, implementing something different from its previous path is risky, but it is the only way to improve,” he said.
He also acknowledged that reform is a gradual process requiring persistence and long term commitment.
“Reform cannot be 100 percent successful all the time, but if we don’t do it at all, it means zero improvement. However, if we dare to take one step of reform, it will become the basis for us to continue reform,” he said.
Six Key Priorities for Cambodia’s Tax Sector
Prime Minister Hun Manet outlined several recommendations aimed at strengthening Cambodia’s tax administration and improving public service delivery. One major priority is continuing reforms under the Pentagonal Strategy Phase One, the Revenue Mobilization Strategy, and the Public Financial Management Reform Program.
He also urged tax authorities to provide higher quality and more transparent services to taxpayers while strengthening ethics, professionalism, and discipline among tax officials through continuous training and human resource development.
Another major focus is the modernisation of Cambodia’s tax administration through the use of AI, digital information systems, and international best practices. The Prime Minister encouraged stronger cooperation between ministries and institutions to improve data sharing and support fair tax collection under the legal framework.
According to Hun Manet, the GDT is already working closely with the General Department of Identification and the General Department of Immigration to integrate systems and improve public services through information technology.
New GDT Tower Reflects Cambodia’s Modernisation Vision
The newly inaugurated GDT Tower represents more than just an office building. Officials say it symbolises Cambodia’s broader push toward digital government, institutional modernisation, and stronger governance.
Hun Manet noted that the modern facility will help improve taxpayer services, strengthen revenue mobilisation, and support a more professional and intelligent tax administration system that meets international standards.
He added that Cambodia’s strong economic growth and rising tax revenue have increased the need for modern infrastructure and better human resource development to support future employment opportunities and long term economic expansion.
The Prime Minister also said the building contributes to Phnom Penh’s urban development while reflecting Cambodia’s continued progress in public administration reform and national development.
Tax Reform Supports Cambodia’s Long Term Growth
Government officials believe Cambodia’s growing tax revenue base will play a critical role in financing future development projects and maintaining economic stability. Improved tax collection also helps strengthen investor confidence by creating a more transparent and predictable business environment.
The reforms are part of the Royal Government’s wider strategy to modernise state institutions, strengthen governance, and achieve Cambodia’s long term socio economic vision for 2050. Officials say continued cooperation between the government, private sector, and taxpayers will be essential for sustaining this momentum.
Conclusion
Cambodia’s rapid growth in tax revenue highlights the impact of digital transformation and administrative reform across the country’s public sector. From AI driven systems to improved taxpayer services, the government is positioning the tax sector as a key driver of long term economic development. As Cambodia continues modernising its institutions and expanding digital governance, officials believe the country is building a stronger foundation for sustainable growth and international competitiveness.
