If you own properties in your company or in your personal estate intended for the rental market — or if you are a real estate developer with construction and rehabilitation projects —, you already know that the new Simplified Accessible Rental Regime (RSAA), created by Decree-Law no. 97/2026, offers an unprecedented package of tax benefits. However, the key piece to finalize profitability calculations was missing: what is, after all, the maximum rent amount I can charge in each municipality without losing the tax exemption?
The answer arrived with the publication of Ordinance no. 454/2026/1, of 13 October, which came into force on 14 October 2026 and sets the new official table of maximum rent ceilings by typology and by municipality.
To allow you to calculate the viability of your properties down to the cent and safeguard your tax benefits, we have prepared a practical guide on the new rules, valuation bonuses, and applicable maximum ceilings.
1. What is at stake in your taxes and projects?
Complying with the rent limits defined in this new Ordinance is not a mere administrative detail; it is the direct key to a set of fiscal and urban planning incentives with huge impact on the cash flow of companies and private investors:
- Total exemption from IRS and IRC: Property rental income obtained through contracts framed under the RSAA is exempt from taxation under IRS and IRC.
- IMT and IMI exemptions: Applies to investments intended for the acquisition, construction, and rehabilitation of properties allocated to accessible rental (supplemented by special regimes for alternative investment undertakings).
- Urban Planning Advantages for Developers: Enables the simplified reclassification of rural land to urban and opens the door to exemption from urban development compensation fees in allotment operations or operations of significant urban impact that include supply for accessible rental.
- Alert for Companies: Under IRC, the exemption is not 100%! If you hold properties individually (IRS), the exemption on accessible rental rents is indeed total. However, if the properties are held by a company (subject to IRC), the brake of Article 92 of the IRC Code (Result of assessment) applies.
- What the rule says: The IRC payable by a company cannot be less than 90% of the amount that would be assessed if the company did not benefit from tax incentives.
- The practical effect: The company will always have to pay at least 90% of the IRC it would pay without the exemption, obtaining a maximum effective reduction of only 10% on the IRC assessment.
2. How the new limits are calculated (and the bonus of up to +20%)
The new maximum rent ceilings by typology (from T0 to >T5) were based on 80% of the median rental values published by the INE for each municipality, crossed with the gross area limits for cost-controlled housing.
However, the Ordinance brought excellent news for those who invested in property quality: the table values can be increased (marked up) cumulatively in two objective situations:
- +10% for Parking: If the lease agreement includes private parking.
- +10% for Energy Efficiency: If the property has an energy performance certificate of Class A or higher, valid at the date of signing the contract.
(In practice, an apartment that combines these two characteristics can be rented for a value higher than the base limit of the table for its municipality, keeping the IRS or IRC exemption intact).
3. What if you rent only rooms ("Parts of Housing")?
The diploma also regulates the rental of rooms within the scope of the RSAA. In these cases, the maximum rent ceiling for the room is calculated proportionally to the area, using the formula:

Where the housing limit (Vrefh) is multiplied by the division between the usable area of the room (Auq) and the total usable area of all rooms in the house (Aut).
- The suite bonus: If the rented room has a private bathroom, the usable area of that room (Auq) is increased by 25% in the calculation formula, allowing a higher rent to be charged. The 10% increases for parking and energy class A also apply.
4. Reference Table: Examples of Base Limits by Municipality
Although the Ordinance sets values for all municipalities in the country, we have gathered below some of the main municipalities so you can have an immediate reference of the monthly base ceilings (before applying the parking or energy class bonuses):

(Note: In the last item, "n" corresponds to the number of bedrooms above five).
5. Annual update, data cross-checking, and transitional rules
There are three operational aspects that property owners and real estate company managers must safeguard:
- Automatic update on 1 January: In years when the Government does not review this ordinance, the maximum limits in the table are automatically updated on 1 January in accordance with the annual rent update coefficient of the NRAU.
- Transitional regime (September to 13 October 2026): Although the revocation of the former 2019 ordinances takes effect on 1 September 2026, for contracts concluded between 1 September and 13 October 2026 the limits set forth in former Ordinance no. 176/2019 continue to apply. The new table applies as of 14 October 2026.
- Automatic data cross-referencing: The IHRU will provide an electronic platform with an uplift simulator and will directly cross-check data (via the Public Administration Interoperability Platform) with the Land Registry (IRN), INE, ADENE (to automatically validate the Energy Certificate), and Municipal Councils.
How should your company prepare right now?
In an accessible lease contract, charging just €10 above the statutory limit allowed for your municipality is enough to completely collapse the IRC or IRS exemption. To monetize your property portfolio without tax risks:
- Simulate Net Yield (Open Market vs. RSAA): Often, charging a rent 20% below the top of the market while remaining exempt from IRC/IRS (and IMT/IMI upon acquisition) generates a higher annual net income than traditional leasing.
- Review the Energy Certificate before signing: If your property has the potential to achieve Class A, obtain certification from ADENE before the lease execution date — it is a mandatory prerequisite to add the 10% extra to the rent ceiling.
- Identify Parking Separately: Ensure private parking space is properly identified and included in the contract to justify the additional 10% uplift before the IHRU and the Tax Authority.
