French Corporate Tax Updates Part 1: Tax Loss Carryforward & Audit Developments (April-May 2025)

As France continues to evolve its corporate tax landscape, recent judicial decisions have significant implications for businesses operating in the French market. This first part of our comprehensive analysis covers critical developments in tax loss carryforward rules and audit procedures from April-May 2025.

Tax Loss Carryforward Restrictions: Understanding the Activity Change Rule

One of the most significant developments comes from the Administrative Tribunal of Marseille’s ruling on April 24, 2025 (No. 2204534), which clarifies when companies can lose their ability to carry forward tax losses.

What Changed?

The court reinforced that tax loss carryforwards are subject to strict conditions under Sections 209 and 221,5° of the French Tax Code. Companies cannot carry forward losses if they undergo substantial transformations that fundamentally change their actual business activity.

The Marseille Case: A Practical Example

In this landmark case, a company engaged in both commercial activities and professional property rental was deemed to have changed its core business activity. The trigger? Following the termination of its commercial operations, the company experienced:

• Turnover decline: More than 50% reduction
• Fixed assets reduction: Over 50% decrease
• Workforce reduction: More than 50% cut in employees

Key Takeaway: The 50% threshold across these three metrics appears to be the benchmark for determining whether a business transformation constitutes a “change of activity” that prevents loss carryforward.

Strategic Implications for Your Business

If your company is considering:

• Pivoting business models
• Divesting major business lines
• Significant downsizing

You should carefully evaluate whether these changes might trigger the loss carryforward restrictions. Contact our team for a detailed assessment of your specific situation.

Tax Audit Developments: New Precedents for Businesses

Extended Statute of Limitations for Hidden Activities

The French Administrative Supreme Court’s decision on April 2, 2025 (No. 498921) establishes important precedents for tax audits involving concealed activities.

The Case: A French tax resident who collected undeclared dividends on a Swiss personal account was subject to the 10-year statute of limitations rather than the standard shorter period. The court classified this as “misappropriation of funds constituting illicit activity.”

Impact: This ruling significantly extends the audit window for businesses and individuals involved in:

• Undeclared foreign income
• Concealed business transactions
• Misappropriation of corporate funds

Abnormal Acts of Management: New Flexibility for Director Compensation

The Administrative Court of Appeal of Nancy’s ruling on April 24, 2025 (No. 22NC02867) provides welcome clarity on indirect director compensation.

The Ruling: Payments to third-party companies for services performed by a company’s director are not automatically considered “Abnormal Acts of Management” (AAG) if:

• The payment indirectly remunerates the director
• There is actual consideration for the services
• The arrangement has legitimate business purposes

This decision offers more flexibility for businesses structuring executive compensation arrangements.

Disguised Gifts and Capital Gains Exemptions

The Administrative Tribunal of Nice’s judgment on April 24, 2025 (No. 2301139) highlights the risks of artificial pricing in business transfers.

Warning: If a business sale is requalified as a disguised gift due to artificial price inflation, the transaction loses eligibility for capital gains exemptions under Section 238 quindecies of the French Tax Code.

Online Tax Filing: Burden of Proof Considerations

The Administrative Supreme Court’s recent decision (May 9, 2025, No. 496935) clarifies that online tax return amendments made after legal deadlines are considered “litigious claims.” This places the burden of proof squarely on the taxpayer.

Best Practice: Ensure all tax filings are submitted within statutory deadlines to avoid additional compliance burdens.

Key Takeaways for Today – Part 1

✅ Tax loss carryforwards are lost if business activity changes by more than 50% across turnover, assets, and workforce

✅ Hidden activities trigger a 10-year audit statute of limitations instead of the standard period

✅ Indirect director compensation through third parties can be deductible if properly structured

✅ Online tax filing amendments after deadlines place burden of proof on taxpayers
