With the expansion of cryptocurrency activities in trading, investment, mining, and payment systems, the taxation of digital assets has become an increasingly complex global issue. The decentralized nature of cryptocurrencies, the relative anonymity of transactions, and the ease of cross-border transfers create significant challenges for tax authorities. While many countries have adopted specific tax rules for cryptocurrencies, Iran still lacks a comprehensive and transparent tax framework. In contrast, several European countries, including the United Kingdom, France, Germany, Spain, and Austria, have implemented diverse approaches to cryptocurrency taxation, offering valuable comparative insights.



European tax systems generally classify cryptocurrencies as financial assets subject to income tax or capital gains tax, though their implementation differs. Germany exempts cryptocurrencies held for more than one year from taxation, encouraging long-term investment, while France and Spain impose taxes only upon conversion into fiat currency. These differences demonstrate regulatory flexibility within Europe.



Regarding tax reporting, European countries are moving toward convergence under the EU’s DAC8 framework, which standardizes reporting and facilitates the exchange of tax information. By contrast, Iran has not established a dedicated cryptocurrency tax regime. Current practices rely on the general provisions of the Direct Taxes Act and focus mainly on monitoring banking transactions and cryptocurrency exchanges rather than reducing tax uncertainty. This article argues that Iran should develop a specialized cryptocurrency tax framework inspired by European models to enhance transparency, reduce tax evasion, and improve fiscal oversight.
