IRS tax exemption and reduction for rentals in Portugal: What's new in 2026

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

Faced with the housing crisis that has affected the country for several years, the Portuguese government decided to take strong action in 2026. The goal is clear: to encourage hosts to put their vacant properties and rooms back on the traditional rental market, rather than opting for short-term tourist rentals. At Roomlala, we know how taking the step of renting out space can raise questions, particularly regarding taxes. This is why we are breaking down the very latest government measures for you.

The big news this year lies in the complete overhaul of tax incentives for hosts. If you have a free room in your primary residence in Portugal, renting it out has never been more advantageous. The Portugal rental IRS reduction is now built around two major pillars: 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 settled in the Algarve, a family in Lisbon with an empty student room, or a professional in Porto looking to monetize an unoccupied space, these systems are designed for you. By opting for a Portugal long-term lease, you are not only securing a regular supplemental income, but you are also participating 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 out homestays. From the reduction of the standard tax rate to the total exemption via the new simplified scheme, including the essential administrative steps, you will have all the keys in hand to optimize your rental income with complete legality and peace of mind in 2026.

Understanding the general reduction in taxation on rental income

Even if you do not wish to use 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 flat rate of 28%, which had recently been lowered to 25%. Since January 1, 2026, this standard rate has undergone a drastic cut to encourage long-term rentals.

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 charged does not exceed the ceiling of 2,300 euros per month. For renting a simple homestay room, this ceiling is obviously very widely respected, which ensures that almost all our Roomlala hosts can benefit from this ultra-reduced 10% rate.

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

Case study: Let's take the example of Tiago, who rents a room in his apartment in Faro for 400 euros per month to a young professional. Over a year, he receives 4,800 euros. Under the old 25% scheme, he would have had to pay 1,200 euros in IRS on this income. In 2026, with the new 10% rate, his tax drops 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)?

June 1, 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 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 remove the bureaucratic hurdles that discouraged hosts from joining the affordable rent program.

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

This measure is aimed directly at creating a supply shock 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 headline rent is slightly lower, the total absence of taxation often makes the operation more financially profitable at the end of the tax year.

Case study: Sofia owns a large apartment in Coimbra and wants 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.

The conditions to benefit from the total exemption

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

The second essential condition is compliance with rent ceilings. These ceilings are not set at random: they vary according to municipalities (concelhos), parishes (freguesias), and the type of property (single room, studio, apartment). It is imperative to check the exact ceiling applicable to your property on the official Portal da Habitação simulator (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 residence. It can in no way be used for secondary residences or transitional rentals of a few months. The tenant will also have to justify that this address is becoming their primary tax residence.

Portuguese property owner 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 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 need to provide the tenant's identity (their Portuguese NIF is essential), the lease duration, the rent amount, and specify whether the contract falls under 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.

In addition, you are required 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 issuing these receipts takes just a few clicks, or can even be automated if you set it up.

Exclusions: watch out for Alojamento Local

There is a crucial point of vigilance that we must highlight: 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 vacation rentals that are draining the permanent housing market.

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

This is where the Roomlala proposal makes perfect sense. By moving toward medium and long-term rentals (semester students, year-round young professionals), you avoid the hassles of Alojamento Local, you reduce tenant turnover (less cleaning, less management), and you unlock massive tax benefits. It is a win-win model that is more peaceful and more profitable over the long term.

The benefits for tenants: a major argument for renting

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

For the year 2026, the ceiling for IRS rent deductions for tenants (students, young professionals, families) has been significantly increased. It has risen to 900 euros per year. This means that a tenant declaring their income in Portugal can deduct a large portion 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 host.

This rental tax benefit makes undeclared rentals (the black market) extremely unpopular with younger generations. Today, a student or a young professional will demand a proper 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 host on Roomlala.

Case study: Lucas is a young French engineer recently hired in Porto. He is looking for a homestay to settle in. By choosing a declared room at 400 euros per month, he accumulates legal rental invoices. When filing 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 due. For him, it is a non-negotiable selection criterion: he will always prefer your legal listing to an undeclared offer, thus ensuring the continuity of your Portugal long-term lease.
