Can Land Taxation Help France Solve Its Growing Public Debt Crisis?
With 9,000 billion euros set to change hands in France by 2040, economists suggest that taxing land rent—an asset created by collective public investment—could be an efficient, non-distortionary way to lower public debt and address growing social and geographical wealth inequalities.
Highlights
- •Nearly 9,000 billion euros are expected to be transferred through inheritances in France by 2040.
- •Land value in France is estimated at 6,700 billion euros, representing about half of the nation's total real estate wealth.
- •Economists advocate for land taxation as an efficient, non-distortionary tool for funding public expenditures and reducing debt.
- •Taxing land rents could help address rising real estate inequality and encourage the efficient use of property by heirs.
As France approaches a monumental period of wealth transfer, often termed the "Great Transmission," economists are re-evaluating the role of land taxation as a vital solution for reducing public debt. Projections suggest that approximately 9,000 billion euros will shift from the baby-boomer generation to their heirs by 2040. This economic transition unfolds against a backdrop of significant public financing needs, driven by an aging population, geopolitical instability, and climate change, making the search for efficient fiscal strategies more critical than ever.
The Case for Taxing Land Rent
The core of the issue lies in how we perceive property wealth. An immovable property value is split between the structures built upon it and the land itself. According to INSEE, the value of land in France reached roughly 6,700 billion euros in 2024, accounting for nearly half of the total real estate wealth. Unlike man-made structures, land is not a product of labor; its value is essentially a rent derived from collective factors such as public infrastructure, territorial attractiveness, and local policy decisions.
Economic literature frequently points to land taxation as one of the least distortionary fiscal instruments available. Because land cannot be created or destroyed, taxing it does not discourage investment or reduce the supply of housing, unlike taxes on buildings. This concept finds its roots in the work of economist Henry George and the later "Henry George Theorem" formalized by Richard Arnott and Joseph Stiglitz. These theories suggest that capturing this ground rent is an efficient way for the state to recoup value that it helped create through public investment.
Addressing Inequality and Debt
The current fiscal system often exacerbates geographical inequalities. Between 2001 and 2023, property prices in older residential areas grew much faster than household incomes. Heirs inheriting property in highly desirable urban hubs gain a significant financial advantage, while those inheriting in less developed areas are left at a disadvantage. Furthermore, with approximately 40% of households holding no real estate and the top 10% controlling over 40% of the market, the "Great Transmission" risks cementing these wealth gaps.
Implementing a specific tax on land value during successions could serve a dual purpose. It would provide much-needed revenue to help manage public debt, which currently exceeds 115% of the GDP. Simultaneously, it would incentivize the efficient use of land. By introducing a fiscal cost to holding unproductive land, heirs might be encouraged to rent or sell these properties, thereby increasing housing availability and cooling the overheated real estate market. Ultimately, utilizing the ground beneath our feet could be the key to fostering both fiscal stability and social equity in the years to come.
