French Exit Tax on Large Crypto Holdings Signals Tougher Oversight

French lawmakers have approved a proposal to extend the country's exit tax to crypto-assets exceeding €800,000, targeting wealthy investors who relocate abroad, according to recent parliamentary proceedings. The measure, set to take effect from 1 January 2027 if adopted, would tax unrealized gains on crypto holdings when investors move their tax residence out of France.

The initiative, led by Communist MP Nicolas Sansu and supported across the political spectrum, reflects growing concern over tax avoidance in the fast-expanding crypto sector. The French National Assembly is also backing a plan by centrist Charles de Courson to introduce fines of up to €10,000 for failing to declare self-custody crypto wallets worth €100,000 or more at the end of the year.

The proposed exit tax is designed to mirror existing rules applied to traditional securities. Under current law, a 31.4% flat tax is levied on gains from crypto disposals. However, authorities have struggled to ensure compliance. In 2021, French investors reportedly made €3.5 billion in crypto gains, but declared only €400 million in holdings, according to data cited by lawmakers.

If passed, the changes would impose a substantial regulatory burden on high-net-worth crypto holders. Critics warn the measures could drive capital flight, as investors move assets or themselves abroad to avoid the tax. There are also security concerns about data leaks stemming from mandatory wallet disclosures, which could expose individuals to hacking or extortion risks.

For policymakers, the tax is intended to boost government revenue and bring the crypto market into line with the oversight applied to other financial instruments. Supporters argue it will help close loopholes that have allowed substantial sums to escape taxation. The move may also set a precedent for other EU countries as they consider how to regulate and tax digital assets.

The proposed measures are scheduled for further votes in October and November 2023, with the French Parliament facing a 10 December deadline to pass the annual budget. If enacted, the rules would mark one of the most aggressive crypto tax regimes in Europe, with implications for cross-border investment, compliance standards and privacy in the digital asset sector.
