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

The housing crisis and the opportunity for the Portugal rental income tax 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 objective is clear: to encourage hosts to put their vacant properties and rooms back onto the traditional rental market, at the expense of short-term tourist lets. At Roomlala, we know how taking the leap into renting can raise questions, particularly regarding tax. That 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 hosts. If you have a spare room in your main residence in Portugal, renting it out has never been more advantageous. The Portugal rental income tax reduction now revolves around two major pillars: a general reduction 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 monetise an unoccupied space, these schemes are designed for you. By choosing a long-term lease in Portugal, you not only secure a regular supplementary income, but you also contribute to the national housing effort, all whilst significantly reducing your annual tax burden.

In this article, we will explore in detail how these new laws apply to homestays. From the reduction of the standard tax rate to total exemption via the new simplified scheme, as well as the essential administrative steps, you will have all the keys in hand to optimise your rental income legally and with peace of mind in 2026.

Understanding the general reduction in tax on rental income

Even if you do not wish to enter into capped rent schemes, 2026 brings excellent news for homestay taxation in Portugal. Historically, property income (category F of the IRS) was taxed at a fixed final rate of 28%, which had already been reduced 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 dropped from 25% to just 10%. This measure automatically applies to all new long-term rental contracts, provided that the monthly rent charged does not exceed the cap of 2,300 euros per month. For the rental of a simple homestay room, this ceiling is clearly widely respected, which ensures that almost all our Roomlala hosts benefit from this ultra-reduced rate of 10%.

This drastic reduction changes the game for Portuguese host 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 10% rate, the risk of undeclared renting is no longer worth taking, especially since declaring protects you legally in the event of a dispute.

Practical example: 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 tax 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 officially replaced the old and complex Programa de Arrendamento Acessível with the Regime Simplificado de Arrendamento Acessível (RSAA). The goal of this reform is to remove the bureaucratic hurdles that discouraged hosts from joining the affordable rent programme.

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

This measure aims directly at creating a supply shock for students and young workers who struggle to find accommodation 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 tax often makes the operation more financially profitable at the end of the tax year.

Practical example: Sofia owns a large apartment in Coimbra and wants to rent a room to a student. The median rent for a room in her neighbourhood, 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 takes part in a rewarding social initiative.

The conditions for benefiting from 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 length of the lease. To encourage a genuine long-term lease in Portugal, the minimum duration of the rental contract to benefit from the RSAA in a main residence was reduced to 3 years in 2026, compared to 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 caps. These caps are not set randomly: they vary according to municipalities (concelhos), parishes (freguesias), and the type of property (room only, studio, apartment). It is imperative to check the exact cap applicable to your accommodation on the official Portal da Habitação simulator (managed by the IHRU) before signing the lease and setting your price.

Finally, the accommodation or room rented must meet basic standards of decency and habitability (window, access to bathroom facilities, electrical safety). The RSAA is exclusively reserved for the tenant's permanent residence. It can in no way be used for second homes or transitional rentals of a few months. The tenant will also have to justify that this address is becoming their primary tax residence.

Portuguese host taxes: steps and points of vigilance

Mandatory registration on the Portal das Finanças

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

This step must be carried out within a maximum 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 length of the lease, the amount of the rent, and specify whether the contract is part of the Regime Simplificado de Arrendamento Acessível. It is this box ticked 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 guarantee for the State that the rental is effective and transparent. Rest assured, the Portuguese tax platform was greatly modernised in 2026 and the issuance of these receipts is done in a few clicks, or even automatically if you set it up.

Exclusions: beware of 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 holiday lets that dry up the permanent housing market.

If you rent your room by the night or by the week to 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 licences are increasingly difficult to obtain, and even frozen in cities like Lisbon and Porto.

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

The advantages for tenants: a major argument for renting

Homestay taxation in Portugal 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 keen to settle down for the long term.

For the year 2026, the ceiling for rent deductions on income tax 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 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 host.

This rental tax advantage makes undeclared renting (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.

Practical example: 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. 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, it is a non-negotiable selection criterion: he will always prefer your legal listing over an undeclared offer, thus ensuring the durability of your long-term lease in Portugal.
