2026 property tax: How renting out a homestay can lighten the load

Autumn is often synonymous with the start of the academic year, dropping temperatures, but also the dreaded return of tax assessments. From the end of August 2026, many hosts will discover the amount of their 2026 property tax. And this year again, the bill promises to be steep with another general increase. Facing this growing fiscal pressure, it is legitimate to look for 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 community-minded and lucrative, makes it possible to generate significant additional income for hosts. Better yet, under very specific conditions, this income can be totally tax-exempt. How can you transform that spare 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 peace of mind.

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

Receiving the 2026 property tax assessments, sent out from late August for taxpayers not on monthly payments, may cause some frustration. This year, the economic context continues to directly impact local taxation. Indeed, property tax is experiencing a new increase with an automatic national revaluation of cadastral bases by 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 state-revalued base are any rate increases voted for by municipalities and inter-municipalities. Many municipalities, faced with rising operating costs and the need to finance the ecological transition, have chosen to increase their tax rates 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 rises to 3,024 euros with the national revaluation. If your municipality also decides 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 hosts to find financial optimization levers to compensate for this unavoidable burden.

Homestay rentals: The ideal solution for additional host income

Meeting increasingly strong rental demand

As property taxes rise, another phenomenon is intensifying in France: the housing crisis. Students, young professionals, and seasonal workers are increasingly struggling to find an affordable roof, particularly in large cities and high-demand areas. Renting out an unoccupied furnished room within your primary residence is a direct and civic response to this issue. By opening your door, you provide a secure and welcoming housing solution to someone who is in dire need of it.

At Roomlala, we see a spectacular rise in searches for homestays every year. This lifestyle appeals due to its financial accessibility for the tenant and the human dimension it offers. Whether you have a child's room 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 this room a new purpose while creating social bonds.

A secure and regular source of additional income

Beyond the human aspect, renting a room in your home is a formidably effective financial lever. This additional host income is ideal for cushioning, or even completely offsetting, the impact of the 2026 property tax. By renting 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.

Let us imagine you rent a 12-square-metre room in Bordeaux for 350 euros per month including utilities. 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 with a surplus to fund your leisure activities, renovations, or to cope with inflation. Furthermore, using a secure platform like Roomlala guarantees you reliable payments and a clear contractual framework, thus avoiding unpleasant surprises.

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

Strict conditions regarding the accommodation and the tenant

The great strength of homestay rentals 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, provided that very specific criteria are met. The first absolute condition is that the rented room 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 imperatively be rented furnished, meaning it must include all items essential for 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

To ensure this furnished rental tax regime remains a housing assistance tool 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 charges that you set must not exceed what is considered a reasonable rent cap. 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 metre of living space, excluding charges, are set at:

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

Let us do a simple calculation. If you live in Toulouse (outside Île-de-France) and you rent a 15-square-metre 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 actual expenses.

Points of vigilance: Avoiding pitfalls to keep your exemption

The risk of requalification as industrial and commercial profits (BIC)

It is crucial to understand that complying with rent caps is not a simple recommendation, but a strict obligation. If the set rent exceeds the legal ceiling of 215 euros or 159 euros per square metre according to your zone by even one euro, the tax penalty is final: the income tax exemption for the room is completely lost. There is no pro-rata or partial exemption.

In this case, all 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 receipts are less than 77,700 euros, you will by default fall under the micro-BIC regime, which entitles you to a standard 50% allowance for expenses. Although this allowance is attractive, it remains less advantageous than a total exemption. It is therefore essential to correctly calibrate your rent when drafting the lease.

The concept of independence of the accommodation and the duration of the scheme

Another common pitfall concerns the configuration of the premises. For the exemption to work, the rented room must not be a totally independent unit. If it is a studio converted at the end 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 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 scheme provided for by Article 35 bis of the General Tax Code has been extended by Parliament, but it is currently in effect until 31 December 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 serenely face your property tax while having a wonderful human experience.
