The tax rate on rental income is not just a line on a tax notice. It results from the combination of the progressive income tax scale and social contributions, which produces very variable effective rates depending on the landlord’s marginal tax bracket. Comparing these rates with each other, and with those applied to financial investments since 2026, allows for measuring the actual tax burden of an unfurnished rental investment.
Effective tax rates on rental income according to the marginal tax bracket
Rental income from an unfurnished property is added to other income of the tax household. Therefore, it is subject to the progressive scale, followed by social contributions at a rate of 17.2%. The table below summarizes the overall rate borne by a landlord according to their marginal tax bracket.

| Marginal income tax bracket | Social contributions | Overall effective rate on rental income |
|---|---|---|
| 0% | 17.2% | 17.2% |
| 11% | 17.2% | 28.2% |
| 30% | 17.2% | 47.2% |
| 41% | 17.2% | 58.2% |
| 45% | 17.2% | 62.2% |
A landlord taxed at the 30% bracket thus pays nearly half of their net rents to the tax authorities. This observation drives many property owners to seek deduction mechanisms to reduce the taxable base rather than the rate itself.

Rental income and financial investments: a growing tax gap in 2026
The finance law for 2026 raised the rate of social contributions on certain financial investment income to 18.6%, bringing the total flat tax (PFU) to 31.4%. Rental income, on the other hand, remains subject to social contributions of 17.2%, but includes the progressive scale.
For a taxpayer in the 30% bracket, the effective rate on their rental income reaches 47.2%. The same taxpayer pays only 31.4% on their dividends or interest subject to the PFU. The gap exceeds 15 points.
Conversely, a non-taxable household bears 17.2% on their rents, compared to 31.4% on their investment income under the PFU. In this specific case, rental real estate is fiscally lighter than financial investments.
Thinking in terms of “overall effective rate” becomes a prerequisite for any allocation decision between real estate and investments. Few guides on rental income incorporate this comparison, even though it conditions the actual net profitability.
Micro-property regime or real regime: the direct impact on the taxable base
The choice of tax regime does not change the tax rate, but it alters the base on which this rate applies. The difference in outcome can be considerable.
Micro-property: a fixed deduction of 30%
The micro-property regime automatically applies when the gross rental income of the household remains below 15,000 euros per year. The administration applies a flat deduction of 30% on gross rents. The landlord cannot deduct any actual expenses or amounts for works.
This regime is suitable for owners whose actual expenses represent less than 30% of the rents received. Beyond that, it becomes penalizing.
Real regime: deduction of expenses and mechanism of property deficit
The real regime allows for the deduction of all deductible expenses borne by the owner:
- Loan interest related to the acquisition or works of the rented property
- Property tax, whose structural upward trend increasingly weighs on net yield
- Management fees, insurance premiums, and maintenance or repair expenses
- Improvement works (excluding construction or expansion)
When deductible expenses exceed the rents collected, the landlord generates a property deficit applicable to global income, up to a limit of 10,700 euros per year. The excess can be carried forward to the rental income of the next ten years.
Property deficit doubled for energy-inefficient homes: the tax lever of 2026
The finance law for 2026 raised the ceiling for applying the property deficit to global income to 21,400 euros per year for owners who carry out works that allow a property to exit the status of energy-inefficient home (labels F or G of the DPE). This doubling is subject to conditions of energy performance and maintaining the property for rent.
For a landlord taxed at 30%, a property deficit of 21,400 euros represents a tax savings of over 6,000 euros, in addition to the savings on social contributions on future rental income absorbed by the carryover of the deficit.
This measure targets a dual objective: to encourage the renovation of the most energy-consuming rental stock and to offer a significant tax advantage to landlords who invest in heavy works. It significantly alters the profitability calculation of a property classified as F or G, as the net cost of works after tax savings decreases markedly.
Declaration of rental income: costly mistakes
The micro-property regime is declared directly on the main income tax return by indicating the gross amount of rents received. The 30% deduction is automatically applied by the administration.
The real regime, on the other hand, requires a specific form. Each expense must be justified. Three common mistakes occur:
- Forgetting to deduct the property tax, which is one of the most significant expenses for a landlord
- Deducting expenses for expansion or construction, which are not eligible under the real rental income regime
- Not carrying forward a previous property deficit, which amounts to losing a benefit acquired in previous years
The choice of the real regime commits the landlord for three years. Switching from micro-property to real requires prior calculations over several years, taking into account planned works and the foreseeable evolution of property tax.
The tax rate on rental income depends less on the scale itself than on the landlord’s ability to reduce their taxable base. With a doubled property deficit for energy renovations and a growing tax gap compared to financial investments, the fiscal management of an unfurnished rental investment relies on technical arbitrations that vary from one household to another.
