DIAN has issued Resolution No. 000240, mandating that cryptocurrency exchanges and service providers report user transactions involving Bitcoin, Ethereum, and stablecoins such as USDT and USDC. This requirement aligns with the OECD's Common Reporting Standard for Automatic Exchange of Financial Account Information (CARF) and will take effect from the 2026 tax year, with the first reports due in May 2027. The resolution requires detailed reporting, including account holder identities, transaction amounts, volumes, and market values. Non-compliance could result in penalties of up to 1% of the transaction value. Additionally, any single transfer exceeding $50,000 will be automatically reported to authorities.
