France’s flat tax on crypto capital gains (PFU) rose to 31.4% on January 1, 2026, as the European DAC8 directive forces platforms to transmit user data to tax authorities. Meanwhile, public debt surpassed EUR 3,595 billion, roughly 119% of GDP. A triple shift that reshapes the country’s crypto fiscal landscape.
🔑 Key takeaways
- The flat tax (PFU) increased from 30% to 31.4% on January 1, 2026, driven by a 1.4-point CSG rise on capital income.
- The European DAC8 directive mandates automatic tax data transmission by crypto platforms since January 2026.
- Pending PLF 2027 amendments target stablecoin conversions, plus an exit tax above EUR 800,000 and self-custody wallet disclosure from EUR 100,000.
- Public debt reaches EUR 3,595bn (~119% of GDP), with interest charges exceeding EUR 77bn in 2026.
- The EUR 305 rule: annual payments in crypto for goods and services under this threshold remain exempt from the flat tax.
A higher flat tax, not a brand-new tax
France has no crypto-specific tax. The change stems from an increase in the contribution sociale generalisee (CSG) on capital income, voted as part of the 2026 social security financing law. CSG on capital income rose from 9.2% to 10.6%, a gain of 1.4 points. Because gains from selling crypto by individuals fall under the same regime as other capital income, they absorb the full increase.
The calculation mechanics remain unchanged. Annual net capital gains (gains minus losses on disposals) face a combined rate of 31.4%, split between 12.8% income tax and 18.6% social levies. For an investor with EUR 10,000 in net gains, the bill goes from EUR 3,000 to EUR 3,140. The difference is modest on a small portfolio, but it stacks on top of other deductions in place for years.
What does not change is the reporting logic. Exchanging one cryptocurrency for another is not inherently taxable. Only converting into euros, or using crypto to buy goods and services, creates a taxable capital gain. Transactions must be declared on Form 2086, and accounts opened with foreign platforms on Form 3916-bis. These obligations have existed for a long time, but many individuals neglected them due to light enforcement.
The breakdown in detail
| Component | Rate | Detail |
|---|---|---|
| Income tax | 12.8% | Fixed PFU component |
| CSG (2026) | 9.2% to 10.6% | 1.4-point increase |
| CRDS | 0.5% | Unchanged |
| Social levies | 18.6% | Total after increase |
| PFU total | 31.4% | Up from 30% before 2026 |
DAC8: the end of platform opacity
The real structural change is DAC8. This European directive, in force since January 1, 2026, requires crypto-asset service providers to collect and transmit user and transaction data to tax authorities. Identity, country of residence, volumes, balances: the administration now receives structured data without opening an investigation.
For tax authorities, this is a major advance. For years, foreign platforms and decentralized exchanges made it possible to stay under the radar. With DAC8, transparency becomes the rule for centralized platforms registered in the European Union. Platforms failing to comply face penalties, and users who forgot to declare an account abroad risk a tax reassessment.
Some nuance is needed, however. DAC8 does not cover hardware wallets or fully decentralized protocols with no identifiable provider. The directive therefore shifts the problem without eliminating it. It does make checks far easier for taxpayers using regulated platforms, which account for the bulk of the retail market.
At the same time, the European MiCA regulation, governing crypto-asset service providers, moves into full application, with the CASP license required from July 1, 2026. Again, the goal is to professionalize the sector and make it more traceable.
Public finances under strain
The rise in crypto taxation is not isolated. It fits a budget situation that the Cour des comptes (France’s supreme audit institution) describes as worrying. According to the latest INSEE figures, French public debt stood at EUR 3,536.1 billion at the end of Q1 2026, or 117.5% of GDP. In Q2, it passed EUR 3,595 billion, approximately 119% of GDP.
These figures place France among the most indebted countries in the euro area, behind Greece and Italy in available data. The country also still runs a high public deficit: 5.1% of GDP in 2025, against an initial forecast of 5.4%. However, the Cour des comptes notes that this improvement is due “exclusively to tax and social contribution increases”, while spending savings have once again been postponed.
“Interest charges will exceed EUR 77 billion in 2026, more than the state spends on national education, roughly EUR 64.5 billion.”
Cour des comptes, 2026 public report
The problem goes beyond the debt stock. It lies in the cost of servicing that debt. The Cour des comptes estimates interest charges will exceed EUR 77 billion in 2026, more than the state spends on national education, roughly EUR 64.5 billion. In other words, a growing share of tax revenue goes to paying interest on past borrowing without funding current services.
Public debt trajectory
| Period | Debt (EUR bn) | Share of GDP |
|---|---|---|
| Q1 2026 | 3,536.1 | 117.5% |
| Q2 2026 | ~3,595 | ~119% |
| Cour des comptes 2026 scenario | > 3,620 | 118.5% |
| Interest charges 2026 | > 77 | — |
The Cour’s central scenario is blunt. Even if the government’s forecasts come true, debt would keep rising past EUR 3,620 billion, or 118.5% of GDP in 2026. The government’s 5%-of-GDP deficit target for 2026 is itself described as “far from assured”, notably because geopolitical uncertainty weighs on both revenue and spending.
The EUR 305 rule explained
There is an exemption often misunderstood. When a cryptocurrency is used to pay for goods or services and the total of those payments does not exceed EUR 305 per year, the transaction is exempt from the flat tax. This threshold does not apply to selling crypto for euros: once capital gains from disposals accumulate, they become taxable regardless of transaction frequency. Many individuals confuse these two regimes, which explains a significant share of reporting errors recorded each year.
This distinction matters more than ever with DAC8. Platforms will transmit detailed data, and the administration can match purchases, sales and withdrawals against bank accounts. A taxpayer who picked the wrong regime in good faith will no longer be able to claim ignorance of the flows. Specialists recommend keeping a precise log of every transaction, starting with the very first purchase.
A debate that goes beyond crypto
Crypto is sometimes presented as a special case. That is a perspective error. Cryptocurrencies still represent a modest share of French household savings, although more than 10% of French people have held them, according to a 2025 ADAN and KPMG study. The core debate concerns fairness in taxation between labor income and capital income, and the role the state intends to give taxes on investments in funding social protection.
The CSG increase on capital income was voted to finance the social security system. It therefore affects all savers: stocks, life insurance, bonds and crypto gains. The political choice is openly acknowledged: rather than cut certain spending, the majority preferred to widen the tax base. Critics answer that spending itself keeps growing faster than national wealth. The Cour des comptes’ finding that savings have once again been “postponed” supports that argument.
Pending PLF 2027 measures
Overnight, the National Assembly’s finance committee approved several crypto amendments as part of the 2027 Finance Bill (PLF 2027). The most sensitive: taxing conversions from a cryptocurrency into a stablecoin for French residents, starting in 2027. This is not yet law: the text must still go through floor debate and the final parliamentary vote.
The other measures under review point in the same direction:
- Exit tax for holders of more than EUR 800,000 in crypto assets who leave France.
- Mandatory disclosure of self-custody wallets (held without an intermediary) worth at least EUR 100,000.
- The committee rejected extending the wealth tax (IFI) to digital assets.
- One measure favorable to investors would allow crypto losses to be carried forward for 10 years.
Tax increases as a recurring pattern?
The link between crypto taxation and public finances is obvious. When the state needs revenue and savings are slow to materialize, it turns to the taxpayers who are easiest to identify. Capital income, capital gains and digital assets are among those targets. Savers, investors and crypto holders share one trait: with DAC8, they are visible, and they do not carry the same political weight as large groups of employees or retirees.
But the question is not only who pays. It concerns the trajectory. Debt above 118% of GDP, with interest charges absorbing a growing share of the budget, reduces the state’s room for maneuver in the next crisis. Every rise in borrowing rates means billions more to finance. In this context, higher taxes on capital look like short-term fixes that do not address the underlying issue: controlling public spending.
What to do, concretely, if you hold cryptocurrencies
For an individual, the answer is fairly simple, even if it is not pleasant. Keep a complete history of all your transactions, starting from your first purchase. Declare every disposal, including those made through foreign platforms, and file Form 3916-bis for every account opened abroad. Also plan your flat-tax calculation in advance, taking into account capital losses, which can be offset against gains from the same year.
Tax tracking tools, such as specialized software, can help rebuild these histories and avoid calculation errors. The most important thing is not to wait for a letter from the tax office before getting compliant. With DAC8, the data already exists, and gaps between what the administration receives and what the taxpayer declares will be easier to spot.
Finally, keep the right order of magnitude in mind. The tax treatment of crypto in France remains comparable to that of other financial investments. The 1.4-point increase is real, but it is not a shock for an overall portfolio. The real issue is trust: a heavily indebted state looking for new revenue will be tempted to make taxation heavier and more closely monitored as budget cycles progress. Taxpayers who plan ahead are best placed to navigate these changes.
What comes next?
Several deadlines will shape the coming months. The MiCA regulation requires the CASP license from providers starting July 1, 2026, which should reduce the number of platforms operating opaquely with French residents. The 2027 income tax returns, covering 2026 transactions, will be the first to rely on data reported under DAC8. Finally, every finance or social security financing law can change the rate applied to capital income again.
On the debt side, the trajectory will depend on the government’s ability to hold its 2026 deficit target at 5% of GDP and to stabilize interest charges. The state’s borrowing rates, which have hardened in recent years, directly determine the cost of this debt. Each additional point weighs on the following year’s budget. The Cour des comptes’ scenario, projecting debt above 118% of GDP, is not inevitable, but avoiding it requires difficult choices on spending.
In short
The “new crypto tax” is, in substance, a rise in the flat tax from 30% to 31.4%, combined with stronger tax transparency through DAC8. The Assembly committee’s stablecoin measure, still subject to parliamentary approval, would extend this logic further. The whole picture unfolds against a backdrop where public debt sits at 118 to 119% of GDP and interest charges are becoming one of the state’s largest spending items.
For crypto holders, the immediate issue is simple: declare everything accurately and plan ahead. For the country, the stakes are broader: getting off a path of debt that weighs, year after year, on budget choices and on the capacity to invest in the future.
