French Capital Gains Tax Analysis: German Property Sale

Executive Summary

This analysis calculates French capital gains tax liability for a French tax resident selling German property. The analysis examines how the total tax burden (income tax + social levies) decreases over the holding period due to time-based allowances.

Tax Jurisdiction

German Tax Status: As the property has been held for more than 10 years, there is NO German capital gains tax liability under German tax law (§23 EStG - Einkommensteuergesetz). Germany exempts real estate capital gains for properties held longer than 10 years.

French Tax Liability: However, as a French tax resident, the seller remains subject to French capital gains tax on worldwide assets, including this German property. This analysis focuses exclusively on the French tax liability.

Legal Framework and Tax Rates

Primary Source

All tax rates and allowances in this analysis are based on official guidance from the French tax authority:

Tax Components

French capital gains tax on real estate consists of two parts:

Income Tax (IR): 19% flat rate
- IR = Impôt sur le Revenu (French for “Income Tax”)
- This is the standard income tax levied on capital gains from property sales
Social Levies (PS): 17.2% rate
- PS = Prélèvements Sociaux (French for “Social Levies”)
- These are social security contributions that fund France’s healthcare and social welfare systems
- Composed of: CSG (Contribution Sociale Généralisée), CRDS (Contribution au Remboursement de la Dette Sociale), and other social charges

Combined rate before allowances: 36.2%

Official Time-Based Allowances

According to impots.gouv.fr, these allowances apply based on holding period:

Income Tax Allowances (Article 150 VC of the French Tax Code)

Direct quote from impots.gouv.fr:

“To calculate the amount subject to income tax, this allowance is: - 6% for each year of ownership subsequent to the fifth year and up to the twenty-first year; - 4% subsequent to the twenty-second year of ownership

Overall, exemption from income tax is granted after twenty-two years’ ownership.”

Summary: - Years 1-5: 0% allowance - Years 6-21: 6% per year (total: 96% after 21 years) - Year 22: 4% (reaches 100% exemption)

Important Notes

No Inflation Adjustment: The French tax code does not provide for inflation indexation of the cost base. The capital gain is calculated on the nominal difference between sale price and original purchase price.

Alternative to Time-Based Allowances: Taxpayers may instead opt for a flat-rate allowance of 15% of the purchase price to account for improvement costs if the property has been held for more than 5 years, but this does not constitute inflation adjustment (Source: Notaires de France, CGI art. 150 VB II).

Scenario Parameters

# Define the scenario
selling_price <- 550000  # Sale price in euros
cost_base <- 250000      # Original purchase price (NOT inflation-adjusted)
capital_gain <- selling_price - cost_base

cat("Selling Price: €", format(selling_price, big.mark = ","), "\n")

## Selling Price: € 550,000

cat("Cost Base (Original Purchase): €", format(cost_base, big.mark = ","), "\n")

## Cost Base (Original Purchase): € 250,000

cat("Capital Gain (Nominal): €", format(capital_gain, big.mark = ","), "\n")

## Capital Gain (Nominal): € 300,000

Critical Note: The €300,000 gain is the nominal difference between sale price and original cost base. Per French tax law, there is no adjustment for inflation in this calculation.

Interpretation & Key Findings

Main Conclusions

No Inflation Adjustment: The cost base of €250,000 remains fixed at the original purchase price. The entire €300,000 difference is treated as taxable gain, with no adjustment for inflation over the holding period. This is consistent with French tax law (Code Général des Impôts).
Time-Based Relief: While there’s no inflation indexation, France provides generous time-based allowances that effectively reduce the tax burden on long-held properties according to official rates published by impots.gouv.fr.
Two-Tier Exemption System (per impots.gouv.fr):
- Income tax (19% rate) is fully exempt after 22 years
- Social levies (17.2% rate) are fully exempt after 30 years
Maximum Tax Burden: At 12 years of holding, the total tax is €78,700 (effective rate: 26.2%)
Minimum Tax Burden: At 30 years of holding, the total tax drops to €0 (effective rate: 0%)
Tax Savings Through Holding: Holding the property for 30 years instead of 12 years saves €78,700 in taxes.

Verification of Calculations

To verify the accuracy of our implementation against official sources:

At 12 years holding: - IR Allowance: (12-5) × 6% = 42% - PS Allowance: (12-5) × 1.65% = 11.55% - Matches official formula from impots.gouv.fr ✓

At 22 years holding: - IR Allowance: (21-5) × 6% + 4% = 96% + 4% = 100% - PS Allowance: (21-5) × 1.65% + 1.6% = 26.4% + 1.6% = 28% - Matches official formula from impots.gouv.fr ✓

At 30 years holding: - IR Allowance: 100% (achieved at year 22) - PS Allowance: 28% + (30-22) × 9% = 28% + 72% = 100% - Matches official formula from impots.gouv.fr ✓

Important Distinction

Inflation Adjustment vs. Time-Based Allowances:

Inflation adjustment would increase the cost base each year based on a price index (e.g., CPI), reducing the nominal capital gain. This is used in countries like the UK for certain assets.
Time-based allowances (French system) reduce the percentage of the nominal gain that is taxable based on holding period, but do not change the gain calculation itself.

France uses the latter approach for real estate capital gains taxation, as confirmed by impots.gouv.fr.

Additional Tax Considerations

According to official sources, additional taxes may apply:

Surtax on large gains (Article 1609 nonies G CGI): Progressive surtax of 2-6% on gains exceeding €50,000
Improvement allowance: Alternative flat-rate 15% allowance for properties held >5 years (instead of actual costs)

These additional elements are not included in this analysis but should be considered for complete tax planning.
