France's Crypto Tax Gap: $9.4 Billion Unreported

A recent study by Chainalysis found that over 90% of cryptocurrency gains in France go undeclared, highlighting a significant tax gap in the country.

The analysis estimated that potentially taxable crypto activity in France reached $9.4 billion for 2025, split into payments ($5.2 billion), capital gains ($2.5 billion), and income from sources like mining and staking ($1.7 billion).

However, according to French tax filings, only about 24,000 individuals declared a combined €368 million in net gains for the 2024 income year.

This disparity is consistent with Chainalysis' estimate that non-compliance may exceed 90% in some countries. The company's report notes that more than 90% of people in Sweden did not report their crypto activity.
