2026 property tax: How renting out a homestay can lower your bill

Autumn is often synonymous with the start of the new school year, falling temperatures, but also the dreaded return of property tax bills. From the end of August 2026, many homeowners will discover the amount of their 2026 property tax. And this year again, the bill promises to be steep with a new generalized increase. Faced with this growing tax pressure, it is legitimate to look for sustainable solutions to preserve your purchasing power. At Roomlala, we support thousands of hosts every day who have found the perfect solution: a homestay. This approach, which is both supportive and lucrative, makes it possible to generate a significant supplementary income for the owner. Better yet, under certain very specific conditions, this income can be totally exempt from tax. How do you transform that guest room gathering dust into a real anti-inflation shield? We explain everything you need to know about the taxation of furnished homestay rentals in 2026, so you can approach the tax season with serenity.

2026 property tax increase: Why is the bill getting heavier again?

The receipt of 2026 property tax notices, sent from the end of August for taxpayers who do not pay monthly, is likely to cause some teeth grinding. This year, the economic context continues to directly impact local taxation. Indeed, property tax is undergoing a new increase with an automatic national revaluation of cadastral bases of at least +0.8%. This increase, indexed to inflation, applies systematically to the entire French territory, regardless of local decisions.

But that is not all. Added to this base revalued by the State are any rate increases voted by municipalities and intermunicipalities. Many municipalities, faced with rising operating costs and the need to finance the ecological transition, have chosen to increase their tax rate in 2026. The combination of these two factors leads to a significant increase in the final amount to be paid for many households.

Let us take a concrete example: if your rental base was 3,000 euros last year, it automatically goes to 3,024 euros with the national revaluation. If your municipality decides at the same time to increase its rate by 2 points, the difference on the final bill will quickly amount to tens or even hundreds of euros in additional costs. Faced with this situation, it is becoming urgent for owners to find financial optimization levers to compensate for this unavoidable burden.

Homestay: The ideal solution for a homeowner's supplementary income

Meeting an ever-growing rental demand

While property tax is increasing, another phenomenon is accentuating in France: the housing crisis. Students, young professionals, and seasonal workers are increasingly struggling to find an affordable roof, especially in large metropolitan areas and strained areas. Renting out an unoccupied furnished room within your primary residence is a direct and civic response to this problem. By opening your door, you offer a safe and warm housing solution to someone who is in dire need of it.

At Roomlala, we see a spectacular increase in searches for homestays every year. This lifestyle is attractive because of its financial accessibility for the tenant and the human dimension it offers. Whether you have a child's room that has now left the nest, or a guest room used only two weeks a year, this space represents untapped potential. Transforming it into a living space for a student allows you to give new purpose to this room while creating social ties.

A secure and regular additional income

Beyond the human aspect, a homestay is a formidably effective financial lever. This supplementary income for the owner is ideal for amortizing, or even completely canceling, the impact of the 2026 property tax. By renting out your room for a few hundred euros a month, you can quickly accumulate an annual sum that far exceeds the amount of your local taxes.

Imagine you rent a 12-square-meter room in Bordeaux for 350 euros per month, utilities included. Over a 9-month academic year, this represents a gross income of 3,150 euros. This sum easily covers the national average of property tax, and even leaves you a surplus to finance your hobbies, your renovation work, or deal with inflation. Furthermore, using a secure platform like Roomlala guarantees reliable payments and a clear contractual framework, thus avoiding unpleasant surprises.

Furnished rental taxation: How to benefit from tax exemption in 2026?

Strict conditions linked to the accommodation and the tenant

The great strength of a homestay lies in its extremely advantageous tax framework. Indeed, Article 35 bis of the General Tax Code provides for a total tax exemption on the income generated, subject to meeting very specific criteria. The first sine qua non condition is that the room rented must be an integral part of your primary residence. It must be a room in your own living space, where the tenant generally shares access to common areas (kitchen, bathroom).

The second condition concerns the tenant himself: the room must constitute their primary residence. There is, however, a notable and very practical exception: if your tenant is a seasonal worker, the room can be considered their temporary residence and qualify you for the exemption. Finally, the room must be rented furnished, that is to say, it must include all the essential elements for daily life (bed, bedding, storage, table, chair, lights, etc.), in accordance with the list set by law.

Reasonable rent caps not to be exceeded in 2026

So that this furnished rental taxation remains a housing aid tool and does not become an instrument of speculation, the tax authorities impose a price limit. To benefit from tax exemption in 2026, the annual rent excluding charges that you set must not exceed reasonable rent caps. These caps are revalued each year and published in the Official Bulletin of Public Finances (BOFiP).

For the year 2026, the annual rent caps per square meter of living space, excluding charges, are set at:

• 215 euros per square meter in the Île-de-France region.
• 159 euros per square meter in other French regions.

Let's do a simple calculation. If you live in Toulouse (outside the Île-de-France) and you rent out a 15-square-meter room, the annual rent excluding charges must not exceed 2,385 euros (15 x 159). Spread over 12 months, this represents a maximum monthly rent excluding charges of 198.75 euros to maintain total exemption. To this amount, you can of course add a provision for charges (water, electricity, internet) which must correspond to the reality of the expenses.

Points of vigilance: Avoiding the traps to keep your exemption

The risk of reclassification as BIC income

It is crucial to understand that compliance with rent caps is not a simple recommendation, but a strict obligation. If the set rent exceeds, even by one euro, the legal cap of 215 euros or 159 euros per square meter depending on your zone, the tax penalty is absolute: the homestay tax exemption is totally lost. There is no pro-rata or partial exemption.

In this scenario, all of your rental income becomes taxable in the Industrial and Commercial Profits (BIC) category. You will then have to declare these sums to the tax authorities. If your annual income is less than 77,700 euros, you will default to the micro-BIC regime, which entitles you to a standard 50% allowance for expenses. Although this allowance is interesting, it remains less advantageous than a total exemption. It is therefore essential to properly calibrate your rent when drafting the lease.

The notion of independence of the accommodation and the duration of the provision

Another frequent trap concerns the layout of the premises. For the exemption to work, the room rented must not be totally independent accommodation. If it is a studio converted at the back of your garden, a maid's room under the roof with its own independent entrance from the building's common areas, or a space with its own kitchen and bathroom without any communication with your living space, the tax authorities will consider it a separate dwelling. The exemption of Article 35 bis will not apply, and you will be taxed under the classic furnished rental regime.

Finally, keep in mind the temporality of this tax loophole. The tax exemption provision provided by Article 35 bis of the General Tax Code has been extended by Parliament, but it is currently in force until December 31, 2026. Although it is very often renewed due to its social utility in the face of the housing shortage, it will be necessary to remain attentive to future finance laws. In the meantime, at Roomlala, we strongly encourage you to take advantage of this opportunity in 2026 to calmly face your property tax while living a beautiful human adventure.
