French Taxes for Expats: The Plain-English Map (2026)

French taxation runs on five boxes: income tax (progressive, computed per household), the 30% flat tax on investment income, social charges (the second layer everyone forgets), property taxes, and — for real estate fortunes above €1.3M — the IFI wealth tax. As a French resident you declare worldwide income; as a non-resident, only French-source income. Treaties then decide who actually taxes what. Master those five boxes and nothing on a French tax notice will ever surprise you again.

Am I a French tax resident?

France uses four alternative tests (article 4B of the tax code). Meeting any single one makes you resident:

1. Your household (spouse/partner and children) lives in France;
2. France is your main place of stay — 183+ days is the classic marker, but not the only reading;
3. Your main professional activity is exercised in France;
4. France is the center of your economic interests (where your wealth is managed, your main income arises).

The tax calendar (and your first return)

• Salaries are withheld at source (PAS) from your first French payslip.
• The annual declaration each May-June settles everything — including foreign income, foreign accounts (mandatory disclosure!), and treaty relief.
• Foreign bank accounts and life insurance must be declared every year (forms 3916) — forgetting carries fines per account, and it's the single most common expat filing mistake.

Income tax: the household system that surprises everyone

France taxes the household (foyer fiscal), not the individual — through the "parts" system:

• The progressive scale runs from 0% to 45% by brackets (updated every year — current figures on impots.gouv.fr).
• Your household income is divided by its number of parts (1 per adult, +0.5 per child, +1 from the third child), taxed per part, then multiplied back. Mechanically, families slide down the brackets.
• Salaries and pensions get an automatic 10% deduction (capped) before the scale applies.

Concrete effect: a married couple with two kids on €90,000 pays meaningfully less income tax than a single person on the same €90,000 — a logic that doesn't exist in the UK and only palely in the US. It's also why comparing "headline rates" between countries misleads: the base matters more than the rate.

Investment income: the 30% flat tax (PFU)

Since 2018, interest, dividends and capital gains on shares are taxed at a flat 30% — the PFU (prélèvement forfaitaire unique): 12.8% income tax + 17.2% social charges. Simple, predictable, no bracket anxiety. You can opt for the progressive scale instead in low-income years if it's cheaper.

The real game is choosing the wrapper around your investments:

Social charges: the "second tax" nobody mentions at dinner

Beyond income tax, France levies social contributions (CSG, CRDS & co.) that fund healthcare and social protection:

• On salaries: withheld with your payslip (part of the gross-to-net gap).
• On capital income (interest, dividends, rents, gains): 17.2% — already included inside the 30% flat tax.

The international exemptions worth knowing:

• Covered by another EEA/UK/Swiss social security system? (S1 pensioners, cross-border workers): no CSG/CRDS on capital income — only a 7.5% solidarity levy. Tick boxes 8SH/8SI on the return.
• Non-residents: same logic on French property income — 7.5% (EEA/UK/CH-insured) vs 17.2% (others).
• Americans: since the 2019 agreement, CSG/CRDS is creditable against US tax — money many US filers in France still leave on the table.

Property taxes: simpler than you fear

• Taxe foncière — the owner's annual tax, set by each commune. Typically several hundred to a few thousand euros; generally far below US property-tax levels.
• Taxe d'habitation — abolished for main residences. Still due on second homes, with surcharges up to 60% in tight housing zones (the classic surprise for holiday-home buyers — budget it).
• Buying? Acquisition taxes are covered in the property guide (~7–9% old, ~2–3% new).

The wealth tax (IFI): real estate only, €1.3M+

France's famous wealth tax was reshaped in 2018: the IFI now targets only net real estate wealth above €1.3 million. Shares, funds, assurance vie unit-linked holdings, cash — all out of scope.

Double taxation & treaties: who taxes what

French residents declare worldwide income — but declaring is not the same as paying twice. France's ~120 treaties allocate taxing rights and neutralize double taxation via credits. The two headline cases:

The impatriate regime: up to 8 years of tax gifts 🎁

If you're recruited to work in France after living abroad for the previous 5 calendar years, article 155 B gives you — until December 31 of your 8th year:

• Impatriation bonus exempt from income tax (or a flat 30% exemption for direct international hires);
• 50% exemption on foreign-source dividends, interest and capital gains — enormous for anyone keeping investments abroad (a Luxembourg contract pairs beautifully here);
• IFI on French property only for 5 years.

Almost nobody structures their investments around this regime in time. If you've just arrived (or are negotiating a French offer), this is a this-month conversation, not a someday one — details in the Moving to France guide.

France vs US vs UK — the honest comparison

The honest conclusion: France is heavy on labor income and light where people don't expect — families, main homes, long-held investments, arriving impatriates, and treaty-protected retirees. Whether France is "expensive" for you is a personal calculation, not a slogan. It takes about 30 minutes to run.

Where these figures come from (official sources)

Nothing on this page is invented — every rule and rate is drawn from official French government and tax-authority sources. The headline numbers (brackets, thresholds) are updated each year, so always check the current figure at the source before acting:
