Porta 65 Jovem program in 2026: How to finance your room in a shared housing in Portugal

Faced with soaring rents in major Portuguese cities like Lisbon, Porto, or Coimbra, finding affordable housing has become a real challenge for young people. Fortunately, the Portuguese government offers concrete solutions to alleviate this financial burden. Among them, the Porta 65 Jovem 2026 program stands out as an essential lifeline. At Roomlala, we know how crucial budget concerns are when looking to move, whether for studies or a first job. That is why we have broken down the new rules of this state aid for you.

In 2026, the program underwent significant updates to adapt to the reality of the housing market. Gone are the rigid rent caps that automatically excluded many candidates, making way for a fairer assessment based on the debt-to-income ratio. However, one major subtlety remains: rental contracts covering only an individual room are strictly rejected. So, how can you benefit from this subsidy when living in a homestay or shared housing? This article guides you step-by-step to understand access conditions, adapt your contracts with the help of your Roomlala hosts, and maximize your chances of obtaining this valuable aid.

What is the Porta 65 Jovem 2026 program?

Age and personal situation criteria

The Porta 65 Jovem program is a financial subsidy paid by the Portuguese government (via the IHRU - Instituto da Habitação e da Reabilitação Urbana) aimed at helping young people pay their rent. To be eligible in 2026, the main criterion remains age. The program is aimed at young people aged 18 to 35. However, flexibility is granted for couples: if one of the two members is under 35, the other can be up to 37. This rule also applies to shared housing, where the average age or the age of each co-tenant will be scrutinized closely.

Beyond age, candidates must reside permanently in Portugal, and the concerned housing must be their primary residence. It is mandatory to possess a Portuguese Tax Identification Number (NIF) and have income declared to the Tax Authority (Autoridade Tributária). At Roomlala, we often remind our international users, particularly Erasmus students or expats, that obtaining the NIF is the very first step to take upon arriving in Portugal, well before searching for student room rentals in Portugal.

Let's take a concrete example: Lucas, 24, a young French professional recently settled in Lisbon. He obtained his NIF, works for a local company, and declares his taxes in Portugal. He therefore ticks the first boxes to claim the Porta 65 Jovem. On the other hand, if he were still attached to his parents' tax household in France without declared income in Portugal, his application would be automatically rejected by the government portal.

The 2026 novelty: flexibility on caps and continuous applications

The year 2026 marks a decisive turning point for the Porta 65 Jovem program. Previously, the system operated in very strict application phases (only a few weeks per year) and imposed a maximum rent cap (Teto Máximo de Renda) according to the housing typology and the municipality. If your rent exceeded this cap by even one euro, you were excluded. Now, applications are open continuously throughout the year. You can apply the exact moment you find your accommodation, which takes immense pressure off tenants.

Furthermore, the rent cap is no longer an automatic exclusion criterion. In 2026, the evaluation is primarily based on the tenant's debt-to-income ratio (taxa de esforço)—that is, the portion of their income dedicated to rent payment—and on the reference rent (RMR) of the geographical area. The ideal debt-to-income ratio to receive support is generally between 35% and 60%. If your rent is slightly higher than market standards but your income is modest, the state will adjust the aid according to your actual situation rather than closing the door on you from the start.

Another major 2026 advancement is the possibility of submitting your application even before the final lease signing. You can now present a promise of lease (promessa de arrendamento). If the aid is granted to you, you have a two-month period to sign the final contract and register it. This measure is a real breath of fresh air for young people who could not afford to pay the first months of rent without the guarantee of obtaining the subsidy.

Shared housing and room rental: strict eligibility conditions

Ineligibility of individual room leases

This is the absolute point of vigilance for the Porta 65 Jovem program, and a frequent source of confusion for tenants. Contracts covering only the rental of an individual room (what is known in Portuguese as arrendamento de quartos) are strictly and systematically rejected by the IHRU. The Portuguese government subsidizes entire homes, not isolated parts of homes, for reasons of tax control and market regulation.

This means that if you rent a room in a homestay with a contract that explicitly states you are only renting room number 2, with access to common areas, you will not be able to receive the Porta 65 Jovem. This is a major obstacle for many students looking for shared housing in Lisbon with a subsidy, as many hosts are used to making separate leases for each tenant to facilitate comings and goings.

At Roomlala, we want to be transparent about this point: although individual room rental is our core business and a very economical solution at the base, it requires a contractual adaptation if you wish to benefit from Portuguese state aid. Fortunately, a legal and perfectly viable solution exists to get around this problem without breaking the rules.

The solution: the single shared housing lease (coabitação)

For young people sharing the same apartment to benefit from the Porta 65 Jovem, they must apply under the shared housing regime, called coabitação in Portugal. The sine qua non condition is that all tenants appear on one single lease contract that covers the entire property. They thus become co-holders of the contract.

In this scenario, the group of young people can submit a joint application. The IHRU will then assess the sum of the income of all tenants appearing on the lease to calculate the overall debt-to-income ratio against the total rent of the property. It is imperative that each member of the shared housing meets the age criteria (18-35 years old) and has declared income. If one of the tenants does not meet the conditions, the entire shared housing application risks being compromised or will require complex adjustments.

Let's take the use case of three students, Maria, Inês, and Chloé, who rent a 3-bedroom apartment in Porto. Instead of signing three distinct room contracts at 400 euros each, they ask their Roomlala host to draft a single 1200-euro lease for the entire apartment in all three of their names. They can thus submit a Porta 65 Jovem application in coabitação. If their application is accepted, the financial aid will be paid into the bank account indicated during the application, and they can divide the reduction on their respective share of the rent.

Roomlala hosts: how to adapt your contracts to help your tenants?

As a host on Roomlala, it is in your best interest to accompany your tenants in their procedures. A tenant who receives Portuguese housing aid is a solvent, reassured tenant who will tend to stay in your accommodation longer. To make your offer eligible for the Porta 65 Jovem in 2026, the first step is to agree to group your tenants under one lease contract (co-tenancy) if you rent several rooms in the same independent apartment.

If you are renting a room within your own primary residence (classic homestay), the situation is more delicate because you cannot rent the entire property. In this specific case, the Porta 65 is unfortunately not applicable. However, if you own an apartment dedicated to shared housing, the switch to a single lease is the key. We advise you to draft this contract carefully by including a solidarity clause, which protects you in case of payment default by one of the tenants.

The other mandatory legal obligation is the registration of the rental contract (or lease promise) with the Portuguese Tax Authority (Autoridade Tributária e Aduaneira - AT). Without the AT registration receipt and payment of the Stamp Duty (Imposto do Selo), your tenants' application will be rejected. At Roomlala, we strongly encourage all our hosts to regularize their contracts. This not only ensures eligibility for aid for young people but also protects you legally and allows you to deduct certain expenses from your rental income.

Finally, do not hesitate to provide your future tenants with a promise of lease (promessa de arrendamento) duly signed. As mentioned previously, the 2026 law allows young people to apply with this simple document. This reassures them about their ability to pay the rent before committing definitively, and it ensures you rent your property to young people supported by the state. It is a win-win relationship that we value enormously on our platform.

How to submit your application for this housing aid in Portugal?

Necessary documents and the online procedure

The application for the Porta 65 Jovem program is done exclusively online via the Portal da Habitação (portaldahabitacao.pt). Thanks to tax identifiers (NIF) or the Chave Móvel Digital (Digital Mobile Key), the process is greatly simplified in 2026. The interface now automatically retrieves a large part of your tax data, thus reducing paperwork.

Here is the list of essential items to prepare to build your file:

• Your NIF and your access to the tax portal (Portal das Finanças).
• The lease contract registered with the AT or the signed lease promise.
• Electronic rent receipts (recibos de renda) if the lease has already started.
• The income tax return (IRS) from the previous year to prove your resources.
• Proof of identity (Cartão de Cidadão or passport with residence permit).
• The RIB (IBAN) of the bank account into which the aid will be paid.

In the context of shared housing, the main candidate (the one who initiates the request on the portal) will have to invite the other co-holders of the lease via the platform. Each tenant will then have to log in with their own credentials to validate their participation in the application and confirm their tax data. It is a collaborative process that requires good coordination between the members of the shared housing.

The payment and renewal of the subsidy

Once the application is submitted, the IHRU has a period to analyze the file. With the 2026 continuous application system, responses are generally faster. If your request is approved, the financial aid is granted for an initial duration of 12 months. The amount of the subsidy is paid monthly, directly into the indicated bank account, generally around the 8th of each month.

It is important to note that this aid is not granted for life. It is renewable for successive 12-month periods, up to a maximum of 5 years (60 months). To keep the aid, you must imperatively submit a renewal request each year, proving that you still meet the conditions (age, income, remaining in the accommodation). Furthermore, the amount of the aid is degressive over the years, the state's goal being to accompany young people toward progressive financial autonomy.

In conclusion, the Porta 65 Jovem 2026 is a fantastic tool to finance your shared housing or rental in Portugal. Although the rules regarding individual room leases are strict, communication with your Roomlala host to establish a coabitação lease is the key to success. Do not wait any longer to talk about it with your future housemates and hosts, and fully enjoy your Portuguese experience without sacrificing your budget!
