ITP Tax When Buying Property in Spain: Rates, Calculation and Reduction Strategies
The Impuesto sobre Transmisiones Patrimoniales (ITP) is the tax payable on the purchase of a used property in Spain. The rate varies by region: 7% in Andalusia, 10% in Catalonia, and a sliding scale of 8-10% in Madrid. The tax base is the price declared in the public deed or the regional reference value (valor de referencia catastral), whichever is higher. The buyer pays the ITP within 30 days of signing the public deed. This article explains the calculation in detail, the regional variations, the regional reference value system, and the strategies (legitimate ones) to reduce the ITP burden. We also explain the limitations of price-undervaluation as a tax-saving strategy and the consequences of an undervaluation that the tax authority later challenges.

The structure of property purchase taxes in Spain
The tax on a property purchase in Spain depends on whether the property is new or used. New properties (purchased from a developer or first occupation by the buyer) are subject to VAT (IVA) at the rate of 10% on the price, plus stamp duty (AJD) at 1.2-1.5% depending on the region. Used properties (purchased from a previous owner) are subject to ITP at the regional rate, with no separate stamp duty.
The distinction between new and used is therefore the first question to settle. A property is considered "new" for tax purposes only at its first transfer from the developer to the first buyer. Any subsequent sale (even if the property has never been occupied) is a "used" property transfer subject to ITP. The treatment depends strictly on the nature of the seller (developer vs. private owner) and on the sequence of transfers, not on the physical condition of the property.
Regional ITP rates
ITP is a regional tax and the rates vary significantly: Andalusia applies 7% on the full tax base (since the simplification in 2021). Catalonia applies 10% on the full base. Madrid applies a sliding scale: 8% up to €400,000, 9% from €400,000 to €700,000, 10% above. Valencia applies 10% with some regional reductions for specific cases. Murcia applies 8%. The Basque Country applies its own rates (typically 4% for ordinary purchases).
The regional rate is determined by the location of the property, not by the residence of the buyer. A British buyer purchasing an Andalusian property pays the Andalusian ITP rate (7%), regardless of where the buyer lives. The differences between regions can be substantial: a €500,000 property generates €35,000 in ITP in Andalusia, €50,000 in Catalonia. The regional tax is one of the factors to consider in the choice of location.
The regional reference value (valor de referencia catastral)
The regional reference value is the minimum value on which ITP can be calculated. The value is set by the Cadastre annually for each property based on market analytics and is typically 70-85% of the actual market value. The reference value is published on the Cadastre electronic office and can be consulted by anyone with the cadastral reference of the property.
The tax base for ITP is the higher of the price declared in the public deed and the regional reference value. If the declared price is below the reference value, the tax is calculated on the reference value (with no possibility for the buyer to challenge except in narrow circumstances). If the declared price exceeds the reference value, the tax is calculated on the declared price. The reference value is therefore a floor, not a ceiling, on the tax base.
Limits on price undervaluation
A common temptation for buyers is to undervalue the purchase price in the public deed to save ITP. The temptation has significantly diminished since the introduction of the regional reference value in 2022, because the tax base cannot fall below the reference value regardless of the declared price. Undervaluation below the reference value is therefore ineffective for ITP purposes.
Undervaluation also creates problems for the buyer later: the lower declared value becomes the acquisition value for the capital gain calculation on any future sale, generating a higher gain and higher capital gains tax. The combined effect of (a) no ITP saving (because of the reference value floor) and (b) higher future capital gains tax makes undervaluation a losing strategy. The declared price should reflect the actual price paid and should be supported by the bank transfers.
Payment of ITP and procedural steps
ITP is paid within 30 days of the public deed signature. The buyer (or, in practice, the lawyer) files Model 600 with the regional tax office, paying the tax by bank transfer or through the regional tax office system. The receipt of payment is essential for the Land Registry inscription: without proof of ITP payment, the Registry will not inscribe the buyer’s ownership.
The payment can be made by the buyer’s own bank transfer or through the notary or the lawyer’s client account. The standard practice is for the lawyer to handle the calculation, the filing, and the payment, integrated with the rest of the post-closing administrative steps. The integrated handling avoids delays and ensures that the inscription at the Land Registry can proceed without obstacles.
Reductions and bonifications
Several regions offer reductions and bonifications of ITP for specific categories of buyers: young buyers (under 35) buying their first habitual home; large families; people with disabilities; victims of terrorism or gender violence. The reductions vary by region and are typically in the form of a reduced rate (4-5% instead of 7-10%) or a fixed amount discount.
The reductions are claimed in the Model 600 with the supporting documentation (proof of age, family book, disability certificate, etc.). The lawyer verifies whether the buyer qualifies for any reduction at the start of the purchase planning. For buyers who qualify, the savings can be significant — a 3% reduction on a €300,000 property saves €9,000.
ITP for new properties: VAT and AJD
For new properties subject to VAT instead of ITP, the tax structure is different. VAT at 10% is paid to the developer at the time of the public deed (the developer then remits the VAT to the tax authority as part of their regular VAT filings). Stamp duty (AJD) at 1.2-1.5% is paid by the buyer to the regional tax authority within 30 days of the public deed, similar to ITP.
The combined burden of VAT (10%) and AJD (1.5%) for new properties is 11.5%, higher than the ITP for used properties in most regions. The higher tax is one of the factors that makes new properties relatively more expensive than equivalent used properties. The buyer should consider the tax difference in the comparison of new vs. used property options.
Treatment of off-plan purchases
Off-plan purchases (new properties bought before construction is complete) are treated for tax purposes as new property purchases, with VAT and AJD applicable. The VAT is paid in installments as the buyer makes payments to the developer during construction. The AJD is paid at the time of the public deed (typically at delivery of the completed property). The detailed treatment is in our guide to off-plan property purchase.
The off-plan buyer should ensure that the developer is properly registered for VAT and that VAT invoices are issued for each payment. This documentation is essential for any potential VAT recovery (if the property is acquired through a Spanish company for business use) and for the subsequent record-keeping of the acquisition value.
Strategies for tax optimisation
Legitimate strategies for ITP optimisation include: structuring the purchase to qualify for regional reductions (e.g., timing the purchase to the year when the buyer is under 35); careful documentation of the acquisition value to enable maximum deductions in any future capital gain calculation; consideration of the regional differences when choosing the location of the property (if the buyer is flexible between Andalusia and Madrid, for example, the Andalusian rate may be preferable for high-value properties).
Aggressive strategies (significant undervaluation, structuring through complex intermediaries) typically backfire and are not worth the risk. The Spanish tax authority has substantial information cross-checking capabilities and detects most undervaluation attempts within 1-4 years. The penalty regime is harsh (typically 50-150% of the unpaid tax), and the buyer ends up paying much more than the original tax saving.
Action steps for the ITP component of the purchase
First: identify the regional ITP rate applicable based on the location of the property. Second: verify the regional reference value of the property at the Cadastre. Third: calculate the expected ITP burden as part of the purchase budget. Fourth: verify whether any regional reductions apply to the buyer. Fifth: arrange the funds for the ITP payment in the purchase planning. Sixth: file Model 600 within 30 days of the public deed through the lawyer. Seventh: retain the payment receipt for the Land Registry inscription. For a full consultation on ITP planning, contact our team.
ITP is a significant cost of a Spanish property purchase that should be planned for from the start.
