The Property Tax, known in Spain as IBI (Impuesto sobre Bienes Inmuebles), is one of the main recurring expenses associated with owning a property. Before buying a property in Madrid, it is important to understand how it is calculated, who is responsible for paying it, when it is due and which information should be reviewed during the purchase process.
In Madrid’s real estate market, particularly when purchasing luxury homes, penthouses, period apartments, villas and investment properties, the IBI tax receipt forms part of the documentation that should be carefully reviewed before signing the reservation agreement or the title deed. It also makes it possible to verify the cadastral reference, the cadastral value and the existence of any outstanding tax debts.
Key fact for 2026: the standard tax rate applicable to urban properties in the municipality of Madrid is 0.414%. This percentage is applied to the taxable base, which is calculated from the property's cadastral value and may include any legally established reductions.
What is IBI or Property Tax?
IBI is a municipal, direct and real property tax levied on the value of certain rights over real estate. Its general legal framework is established in the revised text of the Spanish Local Finance Law.
The tax may apply to urban properties, rural properties and special-category properties. In a standard residential transaction in Madrid, the most common case is an urban property: an apartment, a house, a parking space, a storage room or commercial premises.
Although the legal framework is established at national level, the management and collection of the tax are the responsibility of the relevant local council. As a result, tax rates, payment schedules and certain tax benefits may vary from one municipality to another.
Who must pay the IBI on a property?
As a general rule, the person responsible for paying the tax is the individual who holds the taxable property right on 1 January of the relevant tax year. In most residential properties, this is the owner registered as the legal holder on that date.
This obligation applies regardless of the owner's nationality or tax residency. Therefore, a foreign buyer who purchases a property in Madrid must also pay IBI for as long as they own the property.
In rental properties, the tax bill is generally issued to the owner. However, the lease agreement may stipulate that the tenant assumes certain expenses, provided that the agreement is clear and complies with the applicable legislation.
How IBI is calculated in Madrid
The calculation of IBI starts with the property's cadastral value. Where applicable, the legally established reductions are applied to determine the taxable base. The Madrid City Council then applies the corresponding tax rate, followed by any tax reliefs that may apply.
Indicative formula:
Taxable base × tax rate = gross tax amount
Gross tax amount − applicable tax relief = net IBI payable
For 2026, the standard tax rates published by Madrid City Council are as follows:
Property type
Madrid tax rate in 2026
Urban property
0.414%
Rural property
0.567%
Special-category property
1.141%
Illustrative calculation example
If an urban property had a taxable base of €250,000 and no tax relief applied, the calculation would be:
€250,000 × 0.414% = €1,035
This example is provided for guidance only. The actual amount will depend on the cadastral data, applicable reductions, any differentiated tax rates and the tax benefits available for each property.
What is the cadastral value and why does it affect IBI?
The cadastral value is an administrative value assigned by the Spanish Land Registry (Cadastre). It is determined based on factors such as location, land value, construction characteristics, floor area, use, age of the building and other urban planning considerations.
It should not be confused with the purchase price, the market value, the reference value or the result of a mortgage valuation. A prime property located in Salamanca, Chamberí, El Viso, Jerónimos or Justicia may have a market value significantly higher than its cadastral value.
If the floor area, use, annexes or cadastral description do not match the property's physical reality or the information recorded in the Land Registry, it is advisable to investigate the reason for the discrepancy before proceeding with the purchase.
When is IBI paid in Madrid in 2026?
In the municipality of Madrid, the voluntary payment period for the 2026 IBI is scheduled from 1 October to 30 November 2026, inclusive.
Madrid City Council offers various payment methods, including direct debit, instalment plans and special payment schemes. Some of these options may qualify for tax reductions, provided that the relevant requirements and deadlines are met.
If the tax is not paid within the voluntary payment period, the debt may enter the enforcement stage, resulting in surcharges, interest and, ultimately, compulsory collection procedures.
Who pays IBI when buying or selling a property?
In relation to the City Council, the person legally responsible for the tax is the individual who owns the property on 1 January. However, in a property transaction, it is common practice for the buyer and seller to agree on a proportional division of the tax according to the period during which each party owned the property during that year.
To avoid any uncertainty, the agreed arrangement should be expressly included in the reservation agreement or in the public deed of sale. It is also advisable to request the latest paid IBI receipt from the seller and verify that there are no outstanding debts.
Important: in certain circumstances, outstanding IBI debts may affect the property itself. For this reason, verifying the tax status forms part of a thorough legal and tax due diligence process before purchasing a property in Madrid.
IBI tax relief and exemptions in Madrid
Spanish legislation provides for mandatory exemptions and allows local councils to establish certain tax relief schemes. These benefits are not automatically granted in every case: some must be requested and are subject to specific deadlines, documentation and eligibility requirements.
The situations that may be relevant include:
Protected housing (VPO) during the legally established benefit period.
Large families, depending on the cadastral value and the conditions established by the local regulations.
Installation of solar energy systems for self-consumption.
Special payment plans or direct debit schemes accepted by the City Council.
Properties that qualify for any tax exemption provided by law.
In Madrid, the applicable conditions and percentages may change from one tax year to another. Before applying for any tax relief, it is advisable to review the current tax ordinance and the latest information published by Madrid City Council.
What should you review regarding IBI before buying a property in Madrid?
The IBI receipt should not be reviewed in isolation. To minimise risks during a real estate transaction, it should be compared with the rest of the property's documentation.
Latest IBI receipt: verify the tax year, registered owner, cadastral reference and tax amount.
Proof of payment: confirm that the tax has been paid and request clarification if there is any deferred payment arrangement.
Cadastral reference: ensure that it corresponds exactly to the property being transferred.
Floor area and use: compare the cadastral information with the physical property, the title deeds and the Land Registry.
Annexes: check whether parking spaces, storage rooms or other ancillary units have separate tax receipts.
Outstanding debts: request the necessary documentation to confirm that there are no unpaid amounts.
Tax allocation for the year of sale: clearly specify in writing which party will pay the IBI for the year in which the transaction takes place and in what proportion.
Frequently asked questions about IBI in Madrid
Is IBI calculated based on the purchase price?
No. IBI is calculated using the property's cadastral value and taxable base, not the purchase price paid for the property.
Who pays IBI if the property is sold halfway through the year?
As far as the City Council is concerned, the person who owned the property on 1 January is responsible. However, the buyer and seller may agree to split the tax proportionally, and this agreement should be recorded in writing.
Does a foreign buyer have to pay IBI?
Yes. The obligation is linked to property ownership, not to the owner's nationality or tax residency.
Do the garage and storage room have their own IBI?
It depends on their cadastral and Land Registry status. If they are registered as independent properties, they may have separate cadastral references and individual IBI tax bills.
What happens if IBI has not been paid?
The debt may generate surcharges and interest and may enter the enforcement stage. Before purchasing a property, it is advisable to verify that all IBI payments are up to date.
Can an incorrect cadastral value be challenged?
Yes. Depending on the origin of the error, there are procedures available for correction, declaration or appeal. The appropriate process will depend on the specific circumstances.
