When buying property in Spain, you must pay different taxes, and stamp duty is one of the most important. This tax applies when purchasing a new home or taking out a mortgage, adding to the total cost. Many buyers only realise the actual amount of stamp duty when they begin the legal process.
Understanding how this tax works helps property buyers plan their budgets properly. In this guide, we explain stamp duty, who pays it, how much it costs, and when it applies. Whether you’re a Spanish resident or an investor, this breakdown will help you make an informed decision.
Why is it charged?
Stamp duty, officially known as AJD tax (Impuesto sobre Actos Jurídicos Documentados), applies to legal documents related to property transactions in Spain. It is required when buying a new-build property, signing a mortgage deed, or handling other notarial documents.
The tax ensures that all public deeds are properly recorded in industrial property registries and other official records. It plays a crucial role in securing legal rights over property. Next, let’s explore the exact rates and how they vary across regions.
How much is stamp duty in Spain?
The stamp duty rate depends on the type of property and the region where it is purchased. The tax usually ranges between 0.75% and 1.5% of the property’s value.
Regional stamp duty rates
- Madrid & Castilla-La Mancha – 1.25%
- Catalonia & Balearic Islands – 1.5%
- Andalusia & Valencia – 1.2% to 1.5%
- Other regions – Between 0.75% and 1.5%, based on local regulations
Factors affecting stamp duty
- Property type – New-build properties have a higher stamp duty rate than resale homes.
- Mortgage registration fees – Stamp duty applies to mortgage deeds.
- Additional costs – Some transactions include Land Registry fees and other administrative documents.
Rates can change, so it’s recommended to check with local authorities before purchasing. Now, let’s look at who is responsible for paying this tax.

Exemptions and reductions on stamp duty
Certain property transactions qualify for reduced stamp duty rates or full exemptions. This is especially true for social housing, family transfers, and some business transactions.
Who qualifies for reductions?
- Affordable housing buyers – Lower rates may apply in some regions.
- Resale property purchases – These homes are taxed under the Property Transfer Tax (Impuesto de Transmisiones Patrimoniales) instead of AJD tax.

Stamp duty reductions depend on autonomous community regulations, so buyers should check local laws before purchasing. Next, let’s see how the tax is calculated.
How to calculate stamp duty in Spain
Stamp duty is calculated based on the property’s sale price, mortgage amount, or value recorded in notarial documents.
Formula to calculate stamp duty
Stamp Duty = Property Price x Applicable Tax Rate (%)
Example Calculation:

- Stamp duty rate: 1.2%
- Total tax payable: €3,600

Some regions offer reduced stamp duty rates for first-time buyers and people with disabilities. The exact special rate depends on the autonomous community. Buyers should check local tax offices to confirm their eligibility for tax relief before purchasing a property.
