Cataluña defines 'large property owner' as having five properties and sets ITP at 20%

El Departament de Territori, Habitatge i Transició Ecològica de la Generalitat de Catalunya has formalised housing regulations through resolutions TER/3739/2026 and TER/3740/2026, published in the Diari Oficial de la Generalitat de Catalunya (DOGC n.º 9775). The regulations consolidate a total of 302 municipalities declared as stressed residential market areas, lower the 'large property owner' threshold to five properties, and automatically activate 20% taxation on the Impuesto sobre Transmisiones Patrimoniales (ITP) for new acquisitions by these profiles.

What's Changing

The regulatory framework introduces two key adjustments to the operations of the Catalán real estate market:

• New Map of Stressed Areas: Resolution TER/3739/2026 extends the validity of 'stressed area' status in 118 municipalities (excluding 22 that improved their records compared to the 2024 list), while Resolution TER/3740/2026 incorporates 53 new towns. Overall, Cataluña has a total of 302 municipalities under this regime.
• Reduced 'Large Property Owner' Threshold: exercising the powers granted by Article 3.k) of State Law 12/2023 on the right to housing, the Generalitat defines the condition of 'large property owner' as owning five or more urban properties for residential use located in these stressed areas. Storage rooms and parking spaces are expressly excluded from the count.
• Activation of the 20% Tax Rate: as established in Decree-Law 5/2025 (integrated into Article 641-1.5 of Book Six of the Tax Code of Cataluña), onerous transfers of used properties are taxed at 20% ITP when the buyer is already a 'large property owner' or when an entire residential building is acquired.

Who is Affected

The measure directly impacts individuals and asset-holding companies that accumulate five or more residential properties within the stressed municipalities, as well as investment companies that acquire blocks of properties in Catalán territory.

However, the Direcció General de Tributs i Joc (DGTiJ) of the Generalitat de Catalunya has established delimiting criteria through its interpretative resolutions (Resolution 3/2025 and Resolution 2/2026):

• Exclusion of Primary Residence: for individual buyers, the primary residence does not count among the five units when determining if they meet the 'large property owner' condition for ITP purposes.
• Purchase of Primary Residence Not Penalised: the purchase made by an individual expressly to establish their own primary residence is not taxed at 20%, maintaining the ordinary (10%) or reduced rates that apply.

What it means if you own a property in Cataluña

For property owners and asset investors in regions such as Vallès Occidental, Vallès Oriental, or Barcelonès, the increased tax burden alters profitability calculations for second-hand purchases. By moving from the general ordinary rate for onerous property transfers (10%) to the increased rate of 20%, the tax burden when signing the deed of sale doubles.

Furthermore, anyone who qualifies as a 'large property owner' within this scope is subject to civil obligations regarding rent containment in new rental contracts, and must apply the limits of the official reference index system.

What to do now

Given the entry into force and consolidation of these resolutions, it is advisable to follow several operational steps before committing to any investment:

1. Audit your property portfolio: review the exact number of residential cadastral references owned, excluding garages, storage rooms, and the primary residence for individuals.
2. Verify the Municipality: check if the properties are located within the 302 municipalities currently on the list of the Departament de Territori. Properties located outside stressed areas do not count towards this specific autonomous threshold.
3. Review taxation before signing deposit contract (arras): consult with a registered tax or real estate advisor on the exact tax impact on the ITP settlement before making any down payments or committing to binding payments.
