Buying a Flat in Catalonia for Under 35s: 5% ITP and Actual Costs

Acquiring a second-hand first home in Catalonia requires a financial cushion to cover not only the mortgage deposit but also the transaction taxes. Since the entry into force of Decree Law 5/2025 from the Generalitat de Catalunya, the age threshold for accessing the reduced 5% rate for Property Transfer Tax (ITP) has been extended to include those up to 35 years old, representing a direct saving of half the tax bill compared to the ordinary 10% rate.

Requirements for Applying the Reduced 5% ITP

Property Transfer Tax is levied on the purchase of used properties. Although the general rate in Catalonia stands at 10%, you can pay tax at 5% if you meet four simultaneous conditions on the date the public deed is granted before a notary:

• Buyer's Age: you must be 35 years old or younger at the time of signing. If you buy as a couple and only one of you meets the age requirement, the 5% benefit applies only to their percentage of ownership (generally 50%), with the other half being taxed at 10%.
• Income Limit: the sum of the general and savings taxable bases from your last IRPF declaration (after deducting the personal and family minimum) cannot exceed 36,000 euros. For joint declarations by family units, this cap is not automatically doubled, so it is advisable to review the individual calculation.
• Designated as Primary Residence: the acquired property must become your continuous residence. For the tax authorities, this means effectively inhabiting it within a maximum of twelve months from the acquisition and residing in it for at least three uninterrupted years, except for force majeure reasons covered by tax regulations.
• Property Type: it must be a second-hand dwelling. New-build developments are not taxed under ITP, but rather by VAT (at 10%) and Stamp Duty (AJD).

Numerical Example: Tax Savings for a Typical Purchase in Vallès

To gauge the impact of this measure, let's take as a reference a second-hand multi-family dwelling with a fixed price of 220.000 euros in municipalities such as Sabadell, Terrassa, or Granollers. The contrast between paying tax at the general rate or the reduced rate substantially alters the liquid capital required for the transaction.

Buyers who meet the requirements save a net 11.000 euros on the day they settle their taxes using form 600 from the Agència Tributària de Catalunya (ATC). This amount reduces the previously required savings from 31% of the property's value to 26%, facilitating access for those with stable incomes but a shorter savings history.

Closing Prices vs. Asking Prices in the Catalan Market

When looking for a property, it's common to focus on prices published on real estate portals, but purchase decisions should be based on actual closing prices. According to data from formalised public deeds compiled by the Consejo General del Notariado for July 2026, the average price per square metre recorded in Cataluña was 2.541 €/m², with a year-on-year increase of 7.7%. In the flat segment (multi-family dwellings), the average reached 3.040 €/m² (13.2% more than in July of the previous year).

Furthermore, the Housing Price Index (IPV) from the INE, published by Idescat for the second quarter of 2026, reflects that second-hand housing in Cataluña accumulated a year-on-year rise of 10.9%, surpassing the 6.4% for new builds. In terms of activity, the INE's Property Rights Transfer Statistics recorded a total of 8.407 formalised home purchases in the region in August 2026, of which 6.727 corresponded to the second-hand market.

Mortgage Conditions: Official and Market Rates

Beyond taxation, financing dictates the buyer's monthly outlay. The 1-year Euribor closed September 2026 at 3.247%, according to official resolutions from the Banco de España published in the BOE. Concurrently, the weighted average interest rate for mortgage loans exceeding three years for the acquisition of freehold property granted by financial institutions stood at 3.134% with data from August 2026.

For a mortgage of 176.000 euros (80% of the 220.000 euro flat from the previous example) formalised over a 30-year term at a fixed rate of 3.13%, the resulting monthly repayment is approximately 755 euros. Before reserving a property, it is advisable to calculate that the sum of this repayment and other active loans does not exceed 30% or 35% of the family unit's accredited net income, a credit burden limit usually applied by the risk departments of banking institutions.

Essential Documentation Before Signing the Deposit Contract (arras)

The deposit contract (arras) sets the binding conditions for the sale. In Catalonia, unless expressly agreed otherwise in the wording, the deposit (arras) is presumed to be confirmatory according to the Codi Civil de Catalunya (article 621-8), although it is most common in notarial practice to agree on penal deposit (arras). Before transferring any initial payment, it is essential to verify four documents:

1. Updated Land Registry extract (nota simple): allows you to check who holds legal ownership and if there are any prior mortgages, liens, easements, or tax burdens that must be financially cancelled before signing the deed.
2. Valid certificate of occupancy: an obligatory document in Catalonia for transferring a property and for registering water, gas, and electricity supplies.
3. Energy performance certificate: issued by a competent technician and registered with the Institut Català d'Energia (ICAEN).
4. Certificate of being up to date with community payments: issued by the property administrator or the secretary of the homeowners' association with the president's approval, detailing if there are any approved outstanding special assessments.
