IRS exemption and reduction for property rentals in Portugal: New features for 2026

The housing crisis and the opportunity of the Portugal rental IRS reduction

Faced with the housing crisis that has been affecting the country for several years, the Portuguese government decided to take strong action in 2026. The goal is clear: to encourage landlords to return their properties and spare rooms to the traditional rental market, at the expense of short-term tourist rentals. At Roomlala, we know how much taking the step towards renting can raise questions, especially regarding tax. This is why we are decoding the latest government measures for you.

The big news this year lies in the complete overhaul of tax incentives for landlords. If you have a spare room in your primary residence in Portugal, renting it out has never been more advantageous. The Portugal rental IRS reduction is now structured around two major axes: a general decrease in tax rates for standard long-term leases, and a total exemption under certain affordable rent conditions.

Whether you are a young retiree living in the Algarve, a family in Lisbon with an empty student room, or a professional in Porto looking to monetize an unoccupied space, these measures are designed for you. By opting for a long-term lease in Portugal, you not only secure a regular supplementary income, but you also participate in the national housing effort, while significantly easing your annual tax burden.

In this article, we will explore in detail how these new laws apply to renting rooms in a homestay. From the drop in the standard tax rate to the total exemption via the new simplified scheme, including the essential administrative steps, you will have all the keys to optimize your rental income legally and with peace of mind in 2026.

Understanding the general decrease in tax on rental income

Even if you do not wish to enter into capped rent schemes, 2026 brings excellent news for Portugal room rental taxation. Historically, rental income (Category F of the IRS) was taxed at a fixed final rate of 28%, which had already been lowered to 25% recently. Since 1 January 2026, this standard rate has undergone a drastic cut to encourage long-term renting.

From now on, the standard tax rate on rental income has gone from 25% to just 10%. This measure applies automatically to all new long-term rental contracts, provided that the monthly rent requested does not exceed the ceiling of 2,300 euros per month. For renting a simple room in a homestay, this ceiling is obviously very widely respected, which guarantees that almost all of our Roomlala hosts will benefit from this ultra-reduced rate of 10%.

This drastic reduction changes the game for Portuguese landlord taxes. It allows you to keep a much larger share of your net rental income. The government understood that heavily taxing small landlords discouraged them from declaring their income or renting out their vacant spaces. With a rate at 10%, the risk of undeclared rental is no longer worth taking, especially since declaring protects you legally in the event of a dispute.

Practical case: Let's take the example of Tiago, who rents a room in his apartment in Faro for 400 euros a month to a young professional. Over a year, he receives 4,800 euros. Under the old 25% regime, he would have had to pay 1,200 euros in IRS on this income. In 2026, with the new 10% rate, his tax falls to 480 euros. That is a net saving of 720 euros per year, simply by declaring a standard long-term lease.

The new Regime Simplificado de Arrendamento Acessível (RSAA)

What is the RSAA (formerly Arrendamento Acessível 2026)?

1 June 2026 marked a decisive turning point in housing policy in Portugal with the entry into force of Decree-Law no. 97/2026. This legislative text has officially replaced the old and complex Programa de Arrendamento Acessível with the Regime Simplificado de Arrendamento Acessível (RSAA). The objective of this reform is to lift the bureaucratic hurdles that discouraged landlords from joining the affordable rent programme.

The principle of the RSAA is extremely incentivizing: if you agree to rent your room at a rate at least 20% lower than the median value of rents charged in your municipality, the Portuguese State rewards you with a total exemption (0%) from IRS on this rental income. Yes, you read that right: no tax to pay on the money you earn from renting your room.

This measure directly aims to create a supply boost for students and young workers who struggle to find housing in large cities like Lisbon, Porto, or Coimbra. At Roomlala, we strongly encourage our hosts to study this option: although the nominal rent is slightly lower, the total absence of tax often makes the operation financially more profitable at the end of the fiscal year.

Practical case: Sofia owns a large apartment in Coimbra and wishes to rent a room to a student. The median rent for a room in her neighborhood, according to the Portal da Habitação, is 350 euros. To benefit from the RSAA, Sofia must offer a maximum rent of 280 euros (i.e., 20% less). By renting at 280 euros per month, she receives 3,360 euros per year, tax-free. If she had rented at 350 euros outside the RSAA (taxed at 10%), she would have received 4,200 euros, minus 420 euros in taxes, i.e., 3,780 euros. The financial difference is minimal, but Sofia gains peace of mind, finds a tenant instantly, and participates in a rewarding social initiative.

Conditions to benefit from the total exemption

For this 0% exemption to be applied, the legislator has set strict but simplified rules compared to previous years. The first major condition concerns the lease duration. To encourage a real long-term lease in Portugal, the minimum duration of the rental contract to benefit from the RSAA in a primary residence was reduced to 3 years in 2026, compared to 5 years previously. This increased flexibility reassures landlords who were hesitant to commit for half a decade.

The second essential condition is compliance with rent ceilings. These ceilings are not set randomly: they vary according to municipalities (concelhos), parishes (freguesias), and the property type (single room, studio, apartment). It is mandatory to check the exact ceiling applicable to your accommodation on the official simulator of the Portal da Habitação (managed by the IHRU) before signing the lease and setting your price.

Finally, the housing or room rented must meet basic standards of decency and habitability (window, access to sanitary facilities, electrical safety). The RSAA is exclusively reserved for the tenant's permanent housing. It cannot in any way be used for secondary residences or transitional rentals of a few months. The tenant will also have to prove that this address becomes their main tax residence.

Portuguese landlord taxes: procedures and points of vigilance

Mandatory registration on the Portal das Finanças

At Roomlala, safety and legality are our priorities. To activate your Portugal rental IRS reduction or your total exemption via the RSAA, it is not enough to sign a paper contract with your tenant. Portuguese law is strict: every rental contract must be obligatorily registered with the Tax Authority (Autoridade Tributária) via the Portal das Finanças.

This step must be carried out within a maximum period of 30 days following the signing of the lease. During this online registration, you will have to provide the tenant's identity (their Portuguese NIF is essential), the lease duration, the rent amount, and specify if the contract falls within the framework of the Regime Simplificado de Arrendamento Acessível. It is this box checked and verified by the tax algorithms that will trigger your 0% or 10% rate.

Furthermore, you have the obligation to issue electronic receipts (recibos de renda eletrónicos) each month on this same portal when the rent is paid. This traceability is the State's guarantee that the rental is effective and transparent. Rest assured, the Portuguese tax platform was greatly modernized in 2026 and the issuance of these receipts is done in a few clicks, or even automatically if you set it up.

Exclusions: watch out for Alojamento Local

There is a crucial point of vigilance that we must emphasize: tourist or short-term rentals, known as Alojamento Local (AL), are strictly excluded from these advantageous tax schemes. The government wants to curb the proliferation of holiday rentals that drain the permanent housing market.

If you rent your room by the night or by the week to passing tourists, you will remain subject to the classic tax regime for commercial activities (Category B) or the full rate of Category F, without any possible reduction. Furthermore, Alojamento Local licenses are increasingly difficult to obtain, and even frozen in cities like Lisbon and Porto.

This is where Roomlala's proposal makes perfect sense. By moving towards medium and long-term rental (semester students, young professionals year-round), you avoid the headaches of Alojamento Local, you reduce the turnover of your tenants (less cleaning, less management), and you unlock massive tax benefits. It is a win-win model, more serene and more profitable in the long term.

The benefits for tenants: a major argument for renting

Portugal room rental taxation was not only designed for landlords; tenants also benefit from strong measures in 2026. Knowing how to communicate these advantages is an excellent way for you, hosts, to attract serious, solvent profiles who are eager to settle down for the long term.

For the year 2026, the ceiling for deducting rent from IRS for tenants (students, young professionals, families) has been significantly increased. It has been raised to 900 euros per year. This means that a tenant declaring their income in Portugal can deduct a large part of their housing expenses from their own taxes, on the sole condition that the lease is officially registered and that electronic receipts are issued by the landlord.

This rental tax advantage makes undeclared rental (the black market) extremely unpopular with younger generations. Today, a student or young professional will demand a formal contract to be able to benefit from their 900 euro deduction. By offering a legal and transparent contract from the start, you position yourself as a trusted landlord on Roomlala.

Practical case: Lucas is a young French engineer recently hired in Porto. He is looking for a homestay room to integrate. By choosing a declared room at 400 euros per month, he accumulates legal rental invoices. During his Portuguese tax return the following year, he will be able to deduct up to 900 euros, which will increase his tax refund or decrease his remaining amount to pay. For him, this is a non-negotiable selection criterion: he will always prefer your legal listing to an undeclared offer, thus ensuring the durability of your long-term lease in Portugal.
