France’s New Crypto Tax Rate: 31.4%

On December 16, 2025, the French National Assembly adopted the PLFSS 2026 budget. This law changes cryptocurrency taxation in France: the flat tax rises from 30% to 31.4%, effective January 1, 2026.

This reform doesn’t affect all investments—life insurance and real estate are spared. However, capital gains on cryptocurrencies, stocks, and dividends are directly impacted.

Legal Tax Optimization Strategies

1. Crypto-to-Crypto Exchanges Remain Non-Taxable

In France, only disposals to fiat currency (euros, dollars) or purchases of goods/services trigger taxation. Exchanging BTC for ETH or converting to stablecoins (USDT, USDC) is not a taxable event. You can secure gains without triggering immediate taxation.

2. The €305 Exemption Threshold

If your total annual disposals (conversions to euros) don’t exceed €305, you’re exempt from tax. This strategy suits small investors who want to gradually withdraw gains.

3. Progressive Rate Option

Low-income taxpayers can choose progressive rates instead of the flat tax. If your marginal tax bracket is 0% or 11%, this option may be more advantageous (18.6% to 29.6% vs 31.4%).

4. Donations

Crypto donations to family members can use gift allowances, potentially reducing the tax base for future disposals.
