Introduction to the Single Flat-Rate Levy (PFU) – the 30% Flat Tax
Since January 1, 2018, the single flat-rate levy (PFU), commonly called the "flat tax," has been applied to capital income in France. This tax measure aims to simplify the taxation of investment income by establishing a fixed overall rate of 30%, composed of 12.8% income tax (IR) and 17.2% social contributions. This reform has profoundly changed the tax landscape for investments, but it remains important to understand its terms, alternatives, and real impacts for individual French investors.
Composition and Operation of the PFU
The PFU applies to the following investment income: dividends, interest, capital gains on securities (stocks, bonds, fund shares), as well as gains from the sale of securities and equity rights. The rate is a fixed 30%, broken down as follows:
Income tax: 12.8%
Social contributions: 17.2%
This overall rate is fixed and applies directly to the gross amount of the income concerned, without applying the progressive income tax scale or the usual marginal tax brackets.
Social contributions include the CSG (9.2%), CRDS (0.5%), solidarity levy (7.5%), and other social contributions (0.0% to 0.3%) (source: Bank of France, Annual Report 2023).
Alternatives to the PFU: the Progressive Income Tax Scale
Taxpayers may opt for taxation according to the progressive income tax scale. This option can be advantageous for households whose marginal tax rate (MTR) is below 12.8% or for those benefiting from specific allowances. The choice must be made when filing the annual income tax return.
With the option for the progressive scale:
Dividends benefit from a 40% allowance on their gross amount (before applying the scale).
Interest and capital gains do not benefit from a fixed allowance but are added to other income for income tax calculation.
Social contributions of 17.2% remain payable in addition.
The 2024 progressive scale is as follows (source: INSEE, Tax Bulletin 2024):
Taxable Income Brackets (€)
Marginal Tax Rate (MTR) %

Holding Period Allowances Before the 2018 Reform
Before the PFU was introduced, capital gains on securities benefited from holding period allowances, which reduced the taxable base depending on how long the securities were held. These allowances were as follows (source: AMF, Tax Guide 2017):
Holding Period
Holding Period Allowance (%)
Less than 2 years
0%
2 to 4 years
50%
4 to 8 years
65%
More than 8 years
85%
These allowances no longer apply if the PFU option is chosen. However, if the taxpayer opts for progressive taxation, the allowances can still be used for securities acquired before 2018.
Comparative Simulation: PFU vs Progressive Scale
To assess the tax impact of the PFU compared to the progressive scale, let’s take the example of a household with an MTR of 11% (income bracket between €10,778 and €27,478), receiving €10,000 in dividends in 2024.
Criterion
PFU
Progressive Scale
Gross amount of dividends
€10,000
€10,000
40% allowance
Not applicable
€4,000
Taxable income
€10,000
€6,000
Income tax (MTR 11%)
12.8% flat → €1,280
€6,000 × 11% = €660
Social contributions (17.2%)
€1,720
€1,720
Total taxes and contributions
€3,000
€2,380
Net after taxes
€7,000
€7,620
In this specific case, choosing the progressive scale is more advantageous because the MTR is below 12.8%. Conversely, for a household with an MTR above 12.8%, the PFU is generally more favorable.
Impacts for French Investors
The PFU offers notable simplification and better clarity of taxation on capital income. It also neutralizes the risk of high marginal taxation for highly taxed taxpayers. However, it penalizes low-taxed taxpayers who lose the benefit of allowances and progressivity.
According to a study by the Bank of France (2023), about 60% of taxpayers opt for the PFU, mainly those with an MTR above 14%. Others prefer the progressive scale, notably retirees or low-income households.
Actionable Recommendations for Investors
Analyze your MTR: If your marginal rate is below 12.8%, opt for the progressive scale with a 40% allowance for dividends.
Consider the nature of the income: For capital gains on securities acquired before 2018, the progressive scale with holding period allowances may be beneficial.
Consult a tax advisor: The complexity of the rules requires personalized analysis, especially in cases of mixed income or wealth management strategies.
Simulate annually: The choice between PFU and the progressive scale should be reviewed yearly based on your tax situation and income evolution.
Conclusion
The 30% single flat-rate levy simplifies the taxation of capital income but is not systematically advantageous for all investors. Its fixed rate of 12.8% income tax plus 17.2% social contributions is particularly suited to highly taxed taxpayers. Conversely, for households with a low MTR or those benefiting from holding period allowances, opting for the progressive scale remains preferable. A precise analysis of the individual situation is therefore essential to optimize the tax burden on investment income.
