The new Robien mechanism is based on a tax depreciation of the acquisition price, rather than a tax reduction. This technical distinction conditions the entire asset analysis of the system: depreciation is deducted from rental income (and from global income in case of a deficit), which makes its impact proportional to the taxpayer’s marginal tax rate. Confusing depreciation and tax reduction, as some wealth management advisors still do, skews the profitability calculation from the outset.
Robien depreciation: accounting mechanics and impact on global income
Robien depreciation functions as a fictitious deductible expense. The owner deducts each year a percentage of the acquisition price from their rental income, without having incurred any corresponding actual expense. The rental result then becomes negative, generating a rental deficit that can be deducted from global income.
In the classic version (acquisitions between April 3, 2003, and August 31, 2006), the depreciation rate reaches 8% for the first five years, then 2.5% for the next four, with a possibility of extension in three-year periods. Total depreciation could thus represent up to 65% of the property’s price.
The refocused version (from September 1, 2006, to December 31, 2009) reduced this ceiling: 6% for seven years, then 4% for two years, for a total capped at 50%. The extension beyond nine years was removed. This contraction of the tax advantage was the main reason for the transition to the Scellier system in 2009.
We observe that the decision to invest in new Robien law irrevocably engaged the taxpayer: the choice of the depreciation regime, exercised during the income declaration of the year of completion or acquisition, could no longer be modified afterwards.
Robien rental deficit and capping: what the marginal rate changes
The rental deficit generated by Robien depreciation is deductible from global income up to a limit of 10,700 euros per year. The excess is carried forward to the rental income of the following ten years. This mechanism benefits taxpayers in the higher tax brackets more.
A taxpayer taxed at 30% and another at 41% do not derive the same return from the same Robien property at all. For the latter, each euro of deducted depreciation generates a higher tax saving of one-third. That is why the Robien system structurally favored high incomes, unlike tax reductions like Pinel, which provide the same advantage regardless of the tax rate.
The Robien rental deficit did not fall under the global capping of tax niches (currently set at 10,000 euros per year), as it was part of the rental income regime and not a capped advantage. This technical point, often overlooked, constituted an additional asset for multi-system investors.
Zoning and rent ceilings in new Robien law
The classic Robien had no geographical zone restrictions. Any new housing located in French territory (mainland and DOM) was eligible. This lack of zoning led to investments in less tight rental markets, with difficulties in renting that contributed to the poor reputation of the system in certain medium-sized cities.
The refocused Robien corrected this flaw by limiting eligibility to zones A, B1, and B2, excluding zone C. The rent ceilings were set annually by decree according to the zone, with no resource conditions for the tenant (except in cases of accumulation with the new Borloo supplement).
The rental obligations common to both versions:
- Unfurnished rental, for the tenant’s principal residence, for a minimum duration of nine years
- Rental within twelve months following the completion or acquisition of the property
- Prohibition of renting to a member of the owner’s tax household (renting to an unlinked ascendant or descendant remained allowed under classic Robien)
- Compliance with the applicable rent ceilings for the zone, revised annually
New Robien as a reference point in the current tax debate
The Robien system has been formally closed since the end of 2009, but its tax effects continue to have consequences for properties acquired during the application period. The last Robien recentrized depreciations ceased around 2018-2019 for late acquisitions.
What makes the Robien law relevant beyond its history is its resurgence in recent debates on the taxation of private landlords. Several economists, including Jean-Marc Daniel, have proposed a return to a generalized depreciation mechanism rather than a targeted tax reduction, explicitly taking the Robien model as a reference.
The Jeanbrun system, which came into effect to succeed Pinel, operates under a different logic (tax reduction conditioned on rent and resource ceilings). We recommend that investors carefully compare the two approaches:
- Depreciation (Robien model) reduces the taxable base and benefits higher brackets more
- Tax reduction (Pinel/Jeanbrun model) offers an identical flat-rate advantage regardless of the marginal rate
- The choice between the two depends on the marginal tax rate, asset strategy, and holding horizon
The issue of zoning remains central: where the classic Robien imposed no geographical constraints, recent systems target tight zones. The absence of zoning in the classic Robien was its commercial strength and its asset weakness. Investors who bought in relaxed zones have suffered prolonged rental vacancies and capital losses upon resale.
For taxpayers who still hold a property acquired under Robien, exiting the system after nine years does not trigger any tax recovery, provided that the rental commitment has been respected throughout the period. Resale can occur freely, subject to the classic regime of capital gains for individuals with allowances for holding duration.
