2026 Property Tax: How renting out a homestay can lower your bill

Autumn is often synonymous with back-to-school season, falling temperatures, but also the dreaded return of tax assessment notices. Starting at the end of August 2026, many homeowners will discover the amount of their 2026 property tax. And this year once again, the bill promises to be hefty with another generalized increase. Faced with this growing fiscal pressure, it is legitimate to seek lasting solutions to preserve your purchasing power. At Roomlala, we support thousands of hosts every day who have found the perfect solution: homestay rentals. This approach, which is both supportive and lucrative, allows you to generate a significant additional income for the host. Better yet, under certain very specific conditions, this income can be totally tax-exempt. How can you turn that spare bedroom that is gathering dust into a real anti-inflation shield? We explain everything you need to know about the taxation of homestay furnished rentals in 2026, so you can approach the tax season with peace of mind.

2026 Property tax increase: Why is the bill getting heavier?

The receipt of 2026 property tax notices, sent from the end of August for taxpayers not on monthly payment plans, is likely to make some people cringe. This year, the economic context continues to directly impact local taxation. Indeed, the property tax is undergoing another increase with an automatic national revaluation of cadastral bases of at least +0.8%. This increase, indexed to inflation, applies systematically across the entire French territory, regardless of local decisions.

But that is not all. To this base revalued by the State are added any potential rate increases voted on by municipalities and inter-municipal authorities. 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 extra euros. Faced with this situation, it is becoming urgent for homeowners to find levers for financial optimization to compensate for this inevitable charge.

Homestay rentals: The ideal solution for a host's additional income

Meeting increasingly strong rental demand

As property taxes increase, another phenomenon is intensifying in France: the housing crisis. Students, young professionals, and even seasonal workers are finding it increasingly difficult to find an affordable roof, particularly in large metropolitan areas and tight housing markets. Renting an unoccupied furnished room in your primary residence is a direct and civic-minded response to this issue. By opening your door, you are offering a secure and welcoming 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 appealing because of its financial accessibility for the tenant and the human dimension it offers. Whether you have a child's bedroom that is now empty, 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, homestay rental is a remarkably effective financial lever. This additional income for the host is ideal for cushioning, or even totally offsetting, 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 that you rent a 12-square-meter room in Bordeaux for 350 euros per month including utilities. Over a 9-month university year, that represents a gross income of 3,150 euros. This sum easily covers the national average of the property tax, and even leaves you with a surplus to fund your hobbies, renovation work, or cope with inflation. Furthermore, using a secure platform like Roomlala guarantees reliable payments and a clear contractual framework, thus avoiding any unpleasant surprises.

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

Strict conditions related to the housing and the tenant

The great strength of homestay rental lies in its extremely advantageous tax framework. Indeed, Article 35 bis of the General Tax Code provides for a total income tax exemption on the income generated, subject to meeting very specific criteria. The first condition is that the room being 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 themselves: 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, meaning it must include all items essential to daily life (bed, bedding, storage, table, chair, lighting, 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 tool for housing assistance and does not become an instrument for speculation, the tax authorities impose a price limit. To benefit from tax exemption in 2026, the annual rent excluding utilities that you set must not exceed the caps of what is called a reasonable rent. 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 utilities, are set at:

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

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

Points of vigilance: Avoiding the pitfalls to keep your exemption

The risk of requalification into BIC income

It is crucial to understand that respecting the 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 final: the income tax exemption for homestay rentals is completely lost. There is no pro-rata or partial exemption.

In this scenario, all of your rental income becomes taxable under the Industrial and Commercial Profits (BIC) category. You will then have to declare these sums to the tax authorities. If your annual revenue is less than 77,700 euros, you will by default fall under the micro-BIC regime, which entitles you to a flat-rate allowance of 50% 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 housing and the duration of the provision

Another common pitfall concerns the configuration of the premises. For the exemption to work, the room being rented must not be a completely independent housing unit. If it is a studio apartment at the bottom 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 connection to your living space, the tax authorities will consider it a distinct dwelling. The exemption under Article 35 bis will not apply, and you will be taxed under the standard regime for furnished rentals.

Finally, keep in mind the temporality of this tax loophole. The tax exemption provision provided for 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 housing shortages, 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 experiencing a wonderful human adventure.
