French social charges, known in France as prélèvements sociaux, are levies that fund the country’s healthcare, retirement, and broader social welfare system. As of January 2026, the combined rate on most investment income is 18.6%, up from 17.2%.1Service-Public.fr. Income Tax – Savings and Investment Income They are collected alongside income tax but serve a different purpose: the money is earmarked for France’s social protection system, not the general budget. Whether you pay the full rate, a reduced rate, or almost nothing depends on the type of income, your tax residency, and whether you are covered by another country’s social security system.
What the Charges Fund
Three separate levies make up the total. Each is ring-fenced for a specific purpose, which is why France uses several components rather than a single unified charge.
- CSG (Contribution Sociale Généralisée) is the largest, at 10.6% on investment income. It was designed to spread the cost of healthcare and family benefits across all types of income rather than funding social security through payroll deductions alone.2Legifrance. Code de la Securite Sociale Article L136-1
- CRDS (Contribution au Remboursement de la Dette Sociale) is a 0.5% levy dedicated to paying down accumulated social security debt.
- The solidarity levy (prélèvement de solidarité) is a 7.5% charge that supports additional social programs.
The government cannot redirect CSG revenue to pay down social debt, or use CRDS collections for family benefits. Each euro follows the purpose written into its enabling law.
Current Rates on Investment Income
The 2026 budget raised the CSG rate on investment income from 9.2% to 10.6%, pushing the combined social charges rate to 18.6%. The CRDS and solidarity levy rates did not change.3Justice.fr. Prélèvements Sociaux (CSG, CRDS) sur les Revenus du Patrimoine The breakdown for 2026:
- CSG: 10.6%
- CRDS: 0.5%
- Solidarity levy: 7.5%
- Total: 18.6%
This rate covers dividends, bank interest, capital gains on securities, and furnished rental income. The increase also flows through to the flat tax option, the prélèvement forfaitaire unique or PFU, which bundles income tax and social charges. The PFU rose from 30% to 31.4%, made up of 12.8% income tax plus the new 18.6% in social charges.4Service-Public.fr. Evolution du Taux du Prelevement Forfaitaire Unique (PFU)
Rates on Pension Income
Pensions face lower social charges, and the rate you pay depends on your household’s reference tax income. The CSG on pensions has four tiers: a zero rate for the lowest incomes, a reduced rate of 3.8%, a medium rate of 6.6%, and a normal rate of 8.3%.5Cleiss. The French Social Security System – Rates and Ceilings of Social Security and Unemployment Contributions The 0.5% CRDS applies at every level except the fully exempt tier. A retiree with modest income can pay total social charges as low as 4.3%, while someone above the normal-rate threshold pays around 9.1% on their pension.
Which Income Is Covered
Social charges reach well beyond wages. The main categories:
- Employment income: salaries and professional earnings, with social charges typically withheld by the employer alongside standard social security contributions.
- Self-employment income: independent workers and micro-entrepreneurs pay social contributions calculated as a flat percentage of revenue, with rates varying by activity type.
- Replacement income: pensions, disability payments, and unemployment benefits at the reduced pension rates.
- Investment income: dividends, bank interest, and gains on financial instruments at the full 18.6%.
- Rental income: profits from letting property in France, furnished or unfurnished.
- Real estate capital gains: profits from selling property, with special rules for holding periods and exemptions.
Passive income from investments and property generally faces the full 18.6% rate. Active income (employment, pensions) often carries lower rates or employer-shared contributions.
Real Estate Capital Gains
Property sales come with the most detailed rules, and this is where sellers most often get caught off guard. When you sell, the notary handling the transaction calculates, withholds, and remits both the income tax and social charges owed on the capital gain before you receive the proceeds.6Impots.gouv.fr. Selling Property – Tax Arrangements and Rate Real estate gains do not appear on your annual return.
Your principal residence is fully exempt from both income tax and social charges on the gain, as long as it was genuinely your main home at the time of sale. Temporary or strategic occupation just before selling does not qualify. You can still claim the exemption if you moved out before the sale, provided you placed the property on the market promptly and sold within roughly a year.7Impots.gouv.fr. Exempt Capital Gains
For second homes and investment properties, a holding-period reduction gradually erases the social charges liability. The schedule for social charges is 1.65% per year of ownership from the 6th through the 21st year, 1.60% for the 22nd year, and 9% per year from the 23rd year onward. After 30 years of ownership, the gain is completely exempt from social charges.6Impots.gouv.fr. Selling Property – Tax Arrangements and Rate The income tax abatement is faster, reaching full exemption at 22 years, which creates a window between years 22 and 30 where you owe social charges but no income tax on the gain.
Residency Rules: Who Pays What
Tax residency sets the scope. France treats you as a tax resident if your primary home is in the country, or if you spend more than 183 days there in a given year.8Service Public. How to Determine Your Tax Domicile Professional activity centered in France, or having your main economic interests there, can also establish residency without meeting the day count.
French tax residents owe social charges on worldwide income, including investment returns and rental profits from assets held outside France. Non-residents face social charges only on French-source income, which in most cases means rental income from French property or capital gains on French real estate. A non-resident with only foreign investments and no French-source income has no French social charges liability.
The Big Exemption: EU, EEA, Swiss, and UK Social Security Affiliates
The most valuable exemption applies to people already covered by another country’s social security system. In the De Ruyter ruling, the European Court of Justice held that France cannot impose CSG and CRDS on individuals affiliated with an EU or EEA member state’s social security system, because those levies are directly linked to social security financing and EU rules prohibit double coverage.9EUR-Lex. Ministre de l’Economie et des Finances v Gerard de Ruyter
In practice, qualifying individuals pay only the 7.5% solidarity levy on their French investment income and real estate gains, rather than the full 18.6%. Their foreign pension income is entirely exempt from French social charges. To claim the exemption, you typically need documentation from your home country’s social security office confirming your affiliation. Retirees in France often use an S1 form, which gives them access to French healthcare and simultaneously establishes their foreign social security coverage for tax purposes.10GOV.UK. Healthcare in France
After Brexit, UK nationals who held S1 forms on December 31, 2020, kept the reduced 7.5% rate. New UK retirees who later obtain S1 coverage through the Withdrawal Agreement also qualify. Post-Brexit eligibility can be fact-specific, so it is worth confirming with the French tax office in each case.
What This Means for US Residents
Americans with French investments or property are in a different position. The De Ruyter exemption rests on EU regulations that do not cover the United States, so American investors owe the full 18.6% rate on French-source investment income and real estate gains, regardless of whether they pay into US Social Security.
There is relief on the US side. The IRS and France reached a formal understanding in 2019 that the CSG and CRDS are not social security taxes under the US-France Totalization Agreement. American taxpayers can claim CSG and CRDS as creditable foreign taxes on their US return using the Foreign Tax Credit, rather than having them treated as non-creditable social security contributions.11Internal Revenue Service. French Foreign Tax Credits Before that change, the IRS had routinely denied the credit, creating a genuine double-taxation problem. The solidarity levy portion should be creditable under the same logic, though some tax advisors recommend documenting the claim carefully.
Filing and Compliance
Social charges on most income types are calculated automatically as part of your annual French tax return. The standard form is the Déclaration de Revenus (Form 2042), with supplementary forms such as the 2042-C for additional categories including capital gains and self-employment earnings.12Service-Public.fr. 2025 2024 Income Tax Return (Paper) (Form 10330) Online filing is the default; paper returns are mainly reserved for first-time filers.
Deadlines are staggered by location. The paper deadline is typically in mid-to-late May, and online deadlines run from late May through early June depending on your département. Non-residents usually file on the earliest online deadline. Missing the deadline triggers penalties.
Real estate capital gains are the exception. The notary handles the entire social charges calculation and payment at the time of the sale, so those amounts never appear on your annual return. For a non-resident selling French property, the notary appointment is effectively the only interaction with the social charges system.
If you claim the reduced 7.5% rate as a foreign social security affiliate, expect to supply supporting documentation each year. The tax office will want current proof that you remain covered by your home country’s system, whether that is an S1 form, an attestation from your national social security office, or equivalent evidence. Letting the paperwork lapse means reverting to the full 18.6% rate, and clawing back overpayments retroactively is slow.
