Crypto tax policy: What model for Vietnam’s growth?

As the global cryptocurrency market continues to expand, many countries have introduced different taxation models to regulate and control this digital asset.       

However, according to Dr Chu Thanh Tuan, Associate Program Manager of Undergraduate Business Programs at RMIT University Vietnam, developing an effective tax system should not only focus on creating new revenue streams but also ensure that the policy does not weaken the market or lead to capital outflows to other jurisdictions.

Opportunities for tax revenue from the cryptocurrency market

Vietnam is among the countries with the highest levels of cryptocurrency adoption and interest worldwide. According to a report by Chainalysis, Vietnam ranks fifth globally in cryptocurrency interest and third in terms of using international trading platforms. Currently, around 17 million Vietnamese people own cryptocurrency, with the total market value exceeding US$100 billion.

Dr Chu Thanh Tuan believes that with a reasonable tax mechanism, Vietnam could generate significant revenue from this market. One effective approach is a small transaction tax, similar to the securities trading tax. According to estimates from the Vietnam Blockchain Association, imposing a 0.1 percent tax on each transaction could bring in over $800 million annually without significantly disrupting market activity.

Beyond transaction tax, the government could also consider personal income tax (PIT) on cryptocurrency profits or corporate income tax (CIT) on businesses involved in cryptocurrency trading. If cryptocurrencies are classified as an investment asset, capital gains from transactions could be taxed similarly to securities or real estate. Companies engaged in cryptocurrency trading could also be subject to a 20 percent corporate income tax, similar to traditional businesses.

Another potential revenue stream for the government is charging licensing fees for cryptocurrency exchanges. Many countries have already implemented this model, such as Dubai, where cryptocurrency projects must pay licensing fees. If Vietnam adopts a similar system, it could both regulate the market and generate non-tax revenue.

Challenges in implementing cryptocurrency tax policies 

Despite its revenue potential, implementing a cryptocurrency tax system in Vietnam is not without challenges. According to Dr Tuan, one of the biggest obstacles is the anonymity of cryptocurrency transactions.

Unlike traditional financial transactions, cryptocurrencies operate on a decentralised blockchain network without going through banks, making it difficult to track and control financial flows. Even if Vietnam mandates Know-Your-Customer (KYC) compliance for licensed exchanges, investors can still move their assets to private wallets or use decentralised finance (DeFi) platforms to avoid taxation. This poses a significant challenge for tax authorities.

Moreover, Vietnam’s cryptocurrency legal framework is still in the process of being finalised. While the government is actively discussing cryptocurrency legalisation, there are no official regulations yet on how to classify and manage these assets. According to Dr Tuan, whether cryptocurrencies are considered assets, commodities, or a payment method will directly impact how they are taxed. Without a clear legal definition, it will be difficult to implement a fair and effective tax system.

Dr Tuan also warns of the risk of capital outflows if the tax policy is not well-structured. India serves as a notable example. When the Indian government imposed a 30 percent tax on cryptocurrency profits and a 1 percent transaction tax, domestic trading volume plummeted by 70 percent as investors moved to foreign exchanges. If Vietnam implements excessively high taxes or a complex taxation system, investors may shift their activities to more crypto-friendly jurisdictions like Singapore or Dubai, leading to a loss of potential tax revenue.

Another challenge is the technological limitations in tracking transactions. To tax cryptocurrency effectively, Vietnam needs to invest in advanced blockchain analytics tools. However, Dr Tuan points out that this is difficult because many cryptocurrencies are designed for privacy, such as Monero and Zcash. These tools can make tracking transactions nearly impossible without cooperation from exchanges.

What should Vietnam do to build a tax policy for cryptocurrencies? 

According to Dr Chu Thanh Tuan, to attract investment while ensuring stable tax revenue, Vietnam needs a balanced tax model. A small transaction tax, combined with capital gains tax under the personal income tax framework, could help maintain fairness without weakening the market.

Additionally, Vietnam should consider exempting cryptocurrencies from value-added tax (VAT), as seen in the EU and Singapore, to avoid double taxation and maintain competitiveness in the regional market.

Another crucial measure is strengthening exchange oversight by requiring domestic trading platforms to report transaction details, which would help tax authorities monitor activity more effectively. At the same time, Vietnam should collaborate with international organisations to monitor cross-border transactions and prevent tax evasion.

Instead of solely focusing on tax revenue, the government could also generate income through licensing fees, requiring cryptocurrency exchanges and initial coin offering (ICO) projects to register officially. Establishing a transparent licensing framework would not only increase government revenue but also enhance investor protection and reduce the risks associated with low-quality projects.

Legalising and regulating cryptocurrency trading is a critical step for Vietnam to maximise economic benefits from the sector. However, Dr Chu Thanh Tuan emphasises that the tax policy must be carefully designed to avoid discouraging investment or creating loopholes that facilitate capital flight.

"If Vietnam establishes a simple, competitive, and well-balanced tax system, it can both generate significant revenue from cryptocurrencies and foster the growth of a sustainable digital asset ecosystem," Dr Tuan said.
