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.
How the 31.4% Rate Breaks Down
| Component | Before 2026 | From 2026 |
|---|---|---|
| Income tax | 12.8% | 12.8% |
| CSG (social contribution) | 9.2% | 10.6% |
| Other social levies | 8.0% | 8.0% |
| Total flat tax | 30% | 31.4% |
The 1.4-point increase comes solely from the CSG. The government created the CFA (Financial Contribution for Autonomy) to fund elderly care services.
Concrete Impact: How Much More Do You Pay?

| €100,000 | €30,000 | €31,400 | +€1,400 |
For an investor with €100,000 in Bitcoin gains, the tax bill increases by €1,400.

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.
