Adjustments to the Mais Habitação 2026 program: New benefits of long-term rentals in Portugal

Faced with a housing crisis that has profoundly reshaped the Portuguese real estate landscape in recent years, the Portuguese government has had to rethink its approach. If you are a host, you have most likely followed the heated debates around the first part of the reforms with great interest. Today, in the autumn of 2026, the legislative landscape is clearing up and offering unprecedented opportunities. At Roomlala, we support thousands of hosts and tenants every day, and we have analyzed these recent developments in detail for you. The government's objective is clear: to provide fiscal incentives for hosts to move away from mass tourism, which has become too restrictive, in favor of long-term rentals in Portugal.

In this comprehensive article, we will break down the major adjustments brought about by the new government plan, which replaces the former Mais Habitação 2026 program. From drastic tax cuts to total exemptions under certain conditions, discover how renting out your property or just a room is now one of the most profitable and secure options on the market.

From Mais Habitação 2026 to Construir Portugal: What really changes for hosts

For a long time, the term Mais Habitação resonated as a source of concern for many hosts. Indeed, the first versions of this program imposed rules that were perceived as too restrictive, particularly a strict rent freeze on new contracts, which had the perverse effect of freezing the market and driving away investors. However, faced with the urgency of the situation, the government has made a major strategic shift.

Today, from a legal standpoint, the term Mais Habitação 2026 has become obsolete. It has been officially replaced by the Construir Portugal program. This new action plan, enacted by Decree-Law No. 97/2026 promulgated in May 2026, marks a paradigm shift. The government has understood that it cannot solve the housing crisis without the active cooperation of private hosts. Thus, the strict rent freeze has been lifted to restore confidence among landlords.

The main focus of Construir Portugal is the carrot rather than the stick. The goal is to massively boost long-term rentals in Portugal by making this option financially more attractive than short-term tourist rentals (such as Alojamento Local), which are also facing increasingly heavy local restrictions. For you, as a host, this is the perfect time to rethink your rental strategy and secure your income over the long term without being crushed by the tax burden.

At Roomlala, we are already seeing a significant increase in the number of hosts who are withdrawing their properties from tourist platforms to offer them as shared housing or homestays. This transition is not only supported by law, but it also meets extremely strong local and international demand (students, young professionals, digital nomads).

Revolution in host taxation in Portugal: Drastically reduced tax rates

The shift from 25% to 10% IRS for moderate rents

The flagship measure for the fall of 2026 concerns the easing of host taxation in Portugal. Historically, rental income was heavily taxed, which discouraged putting affordable properties on the market. Decree-Law No. 97/2026 changes the situation: the personal income tax (IRS) rate applicable to rental income is dropping from 25% to a very advantageous 10%.

To benefit from this reduced rate, several simple conditions must be met. First, the monthly rent must be considered "moderate," meaning capped at 2,300 euros per month. Next, the signed lease must have a minimum duration of 3 years. This measure clearly aims to stabilize the market and offer residential security to tenants, while ensuring a very attractive net yield for hosts.

But the real good news, confirmed by a tax clarification published in September 2026, concerns partial rentals. If you decide to rent a room in Lisbon or Porto or in any other city in the country, you are fully eligible for this 10% rate. Furthermore, renting an apartment or a room to a company to house one of its employees also allows you to benefit from this tax advantage.

Concrete example: Let's take the case of Maria, who owns a large apartment in Porto. Until 2025, she rented two rooms to students for a total of 900€ per month, and paid 25% IRS on this income. With the new 2026 law, by signing 3-year leases via Roomlala, her tax rate drops to 10%. She thus saves several hundred euros per year, mechanically increasing her net profitability without having to increase the rent for her tenants.

The Simplified Affordable Rental Regime (RSAA): Total tax exemption

If the 10% rate is already excellent news, the government has gone even further with the creation of the Simplified Affordable Rental Regime (RSAA), which came into force on September 1, 2026. This regime is the direct response to the shortage of housing for the middle class and young professionals.

The principle of the RSAA is extremely powerful: it offers a total tax exemption (0% IRS) on rental income. To be entitled to it, the host must offer a rent at least 20% lower than the median value of the local market (i.e., a rent lower than 80% of the local median).

Point of caution: Please note, this exemption is not automatic. At Roomlala, we want to inform you precisely about the legal steps. To benefit from the RSAA, your rental contract must be registered on the official IHRU (Institute for Housing and Urban Rehabilitation) portal. In addition, the exact rent caps that determine the local median depend on local ordinances (the portarias), the publication of which is spread over the end of 2026. It is therefore crucial to check the cap applicable to your municipality (concelho) before setting your price.

Use case: Joao owns a two-bedroom apartment in Lisbon. The median rent in his neighborhood is estimated at 1,200€. If he decides to rent his property at 950€ (i.e., below the 80% median mark), he will pay absolutely no tax on this income. Although the gross rent is slightly lower than what he could hope for on the free market, the net rent (after taxes) that ends up in his pocket is significantly higher. It is a highly effective tax strategy.

Tenants and hosts: A finally win-win system

Increased tax benefits for tenants

For a rental market to be healthy, both supply and demand must benefit. The Construir Portugal program has not forgotten tenants, who are facing inflation in the cost of living. To help them manage rents and to ensure demand is solvent, the government has increased the tax deductions they can benefit from.

Thus, tenants are seeing their tax deduction cap on rents (deductible from their own IRS) increase significantly. This cap will rise to 900 euros for the 2026 fiscal year and will reach 1,000 euros in 2027. This measure restores purchasing power to tenants.

For you, as hosts, this is excellent indirect news. A tenant who benefits from high tax deductions is a financially more stable tenant, which drastically reduces the risk of unpaid rent. At Roomlala, we foster this relationship of trust: by offering properties or rooms with proper contracts in place, you allow your tenants to benefit from this assistance, while securing your investment.

The end of the strict rent freeze: The return of confidence

As we mentioned, one of the biggest fears linked to the old Mais Habitação 2026 project was the drastic limitation of rent increases when changing tenants or renewing leases. This mechanism had paralyzed many hosts, who were frightened by the idea of seeing their property's profitability frozen for decades despite inflation.

The government has heard these concerns. The removal of this strict freeze as part of Construir Portugal is a strong signal sent to investors and individual hosts. The market is regaining a certain level of freedom, conditioned by fiscal incentives rather than punitive obligations.

This restored flexibility allows hosts to adapt to economic realities while being rewarded if they choose moderate pricing. It is in this climate of renewed trust that room rentals and shared housing stand out as the most agile and protective solutions in 2026.

How to optimize your rental with Roomlala in light of the new laws?

As you can see, host taxation in Portugal has never been more favorable for those who choose long-term rentals. But how can you take advantage of it concretely without getting lost in administrative complexity? That is where Roomlala comes in to simplify your life.

If you have an empty room, now is the time to take the plunge. Renting out a room in Lisbon, Porto, Coimbra, or Faro has become a real breeze tax-wise. By using Roomlala, you gain access to a community of verified tenants (students, seconded workers, expats). We advise you to prioritize medium to long-term leases (over 3 years) to immediately unlock the reduced 10% IRS rate.

To ensure you are in compliance and to benefit from the Simplified Affordable Rental Regime (RSAA) at 0% tax, we recommend that you:

• Check the portarias of your municipality to find out the exact rent cap (80% of the median).
• Draft a clear rental contract, explicitly mentioning the minimum 3-year duration.
• Register this contract on the tax portal (Autoridade Tributária) and on the IHRU portal within the set deadlines (usually within 30 days of signing).
• Use Roomlala's messaging and secure payment system to keep a transparent record of all your transactions, thus facilitating your tax returns.

In conclusion, the end of 2026 marks a historic turning point for real estate in Portugal. Far from the constraints of mass tourism, long-term rentals are reinventing themselves.
