Argentina and Bulgaria have moved to align their crypto tax reporting rules with international standards, with Buenos Aires committing to the OECD’s Crypto-Asset Reporting Framework and Sofia transposing the EU’s DAC8 directive into national law.
The OECD’s Global Forum on Transparency and Exchange of Information for Tax Purposes confirmed on Sept. 14 that Argentina had formally committed to CARF. That makes Argentina the 77th jurisdiction to join the framework, which was developed with G20 countries to extend cross-border tax information exchanges to crypto assets. Argentina is expected to begin automatic information exchanges by September 2029. Before that, it must incorporate CARF into domestic law, build reporting infrastructure, and establish arrangements with other tax authorities. Gaël Perraud, chair of the Global Forum, said the move would give Argentine authorities access to information on crypto transactions conducted abroad and help address tax evasion risks.
Under CARF, crypto-asset service providers such as centralized exchanges and brokers must collect customer identification and transaction data, including names, addresses, jurisdiction of tax residence and tax identification numbers, as well as data on purchases, sales and transfers. The framework does not itself create a new crypto tax and leaves tax liability to domestic law. Data collection already began on Jan. 1, 2026 in 48 jurisdictions, including the UK and EU countries, with many first exchanges due in 2027.
Argentina already requires virtual asset service providers to register under a regime introduced in 2024. The country’s crypto market remains heavily concentrated in stablecoins, which account for 94% of peso-denominated volume, and adoption research cited by a16z Crypto estimated that about one in five Argentines uses crypto.
Separately, Bulgaria adopted amendments to its Tax and Social Security Procedure Code, passed by the National Assembly on September 9 and published on September 15. The new rules implement the EU’s DAC8 provisions and require crypto service providers to register with the National Revenue Agency and report customer identification and transaction information. Providers must submit data electronically once a year by June 30 following the reporting year, with the first period starting January 1, 2026. The reporting covers purchase, sale, transfer and exchange of digital assets by category, number and total volume, including fiat flows, but does not require tracking movements between external private addresses.
Bulgaria’s law does not increase the tax burden or change how the tax base is calculated. The country is late in transposing DAC8, as the EU deadline was the end of 2025, and has also granted only two MiCA licenses through its Financial Supervision Commission, while more than 70 firms have notified the watchdog that they hold licenses from other EU member states. The first EU automatic exchange for 2026 transactions is expected by September 2027.
