The threshold of 23,000 euros in annual rental income crystallizes the boundary between LMNP and LMP. Crossing this line alone is not enough to trigger the transition to professional landlord status. Two cumulative conditions outlined in Article 155 IV of the CGI must be met, and it is precisely the interplay between these two criteria that generates the most costly qualification errors.
Calculating rental income: what the 23,000 euro threshold actually includes
The amount considered for assessing the crossing of the threshold corresponds to the gross rental income including taxes received during the calendar year. Charges re-invoiced to the tenant, provisions for charges included in the rent, occupancy fees: everything is included in the calculation.

We regularly observe landlords who wrongly exclude recoverable charges or rents received during a period of partial vacancy, reasoning on a net amount. The tax administration considers the gross flow, without deductions.
For a landlord who owns several furnished properties, the income accumulates. A studio rented long-term generating just over half of the threshold, combined with a seasonally rented apartment, may be enough to exceed the limit. The question of prorata temporis also arises in the case of starting activity during the year: the income is then annualized to verify the excess.

Exceeding the LMNP ceiling at 23,000 euros only impacts the status if the second condition is simultaneously met: the furnished rental income must exceed the other professional income of the tax household.
Transition from LMNP to LMP: the majority income condition that landlords underestimate
The second condition is the one that traps the most multi-active taxpayers. The income from furnished rentals must represent more than half of the professional income of the tax household, and not of the global income. Pensions, bare property income, dividends: these flows do not enter into the comparison.
An employee whose net professional income far exceeds their furnished rents remains LMNP, even beyond 23,000 euros in income. In contrast, a retiree receiving a modest pension and exceeding the threshold transitions to LMP without any leeway, as their pension is not considered professional income under Article 155 IV.
The trap also closes on couples: it is the tax household that is analyzed. A spouse without professional activity lowers the denominator of the comparison, which can lead to an unexpected transition.
Direct tax consequences of the transition to LMP
The change in status brings several simultaneous effects:
- Deficits from furnished rentals become deductible from global income, but in return, capital gains from sales fall under the professional regime, which is significantly less favorable in the short term than the capital gains regime for individuals.
- The property enters the scope of the IFI from a different angle: professional qualification can modify the wealth management strategy, especially in the case of donations or incorporation.
- Liability for social contributions SSI (formerly RSI) applies to the taxable profit, with a global rate that can represent a significantly higher charge than the 17.2% social contributions applicable in LMNP.
URSSAF controls and reclassifications: an increasing operational risk
Since 2024, URSSAF controls are more actively targeting furnished landlords who have exceeded the 23,000 euro threshold without registering with the social regime for independents. Adjustments often cover multiple years and concern SSI contributions that were never paid.
The typical scenario: a landlord has exceeded the threshold for several years, has never checked the majority income condition, and discovers during a control that they fall under LMP. The regularization then concerns the due SSI contributions, increased by late penalties.
We recommend documenting each year the comparison between furnished rental income and the household’s professional income. A simple spreadsheet is sufficient, but it must be archived with the tax declaration. In the event of a control, this document demonstrates the landlord’s good faith.
SSI registration: the timeline to respect
Registration must occur within the legal deadlines from the start of LMP activity. Waiting for a control notice to regularize worsens the situation. Proactive registration protects against increases and allows for provisioning contributions from the very first relevant fiscal year.
Strategies to stay below the LMNP threshold or absorb the transition to LMP
Artificially reducing rents to stay below 23,000 euros makes no economic sense. Several more relevant levers exist.
- Distributing properties between spouses or through joint ownership allows splitting income flows between several tax households, provided that the legal structure is consistent with the reality of ownership.
- Switching to the real regime in LMNP allows for property depreciation and generating a low or even zero taxable result. This lever does not prevent exceeding the 23,000 euro threshold (calculated on gross income), but it reduces the taxable base and contributions in case of transitioning to LMP.
- Anticipating wealth transmission before transitioning to LMP can prove strategic. Several notaries and tax advisors indicate that the transition to LMP modifies the analysis of the IFI base and the donation strategy, especially for incorporation.
The choice between remaining in LMNP and accepting LMP status depends on the overall profile of the household: level of professional income, holding horizon, exit project. A landlord close to retirement, whose professional income will drop, should model the transition well before liquidating their rights.
The threshold of 23,000 euros remains a technical dividing line between two regimes with distinct fiscal and social consequences. The second condition, that of majority income, solely determines the actual transition. Documenting this comparison each year and anticipating the resulting social obligations remains the most reliable way to avoid an adjustment.
