What is property tax?

The property tax, commonly known as IBI, is an annual tax paid for the ownership of real estate, whether urban, rural, or of special characteristics. This tax is mandatory and managed at the municipal level, meaning each city council is responsible for its collection and regulation. The IBI is calculated based on the cadastral value of the property, which is determined by the Cadastre, an administrative registry under the Ministry of Finance.

Its importance lies in the fact that this tax is crucial for the financing of Spanish municipalities, as it is one of the main sources of income to cover municipal expenses. For example, in 2022, property tax revenue exceeded 14 billion euros. The funds generated by this tax are allocated to various public services, such as education, healthcare, and infrastructure improvements.

What type of tax is IBI?

IBI is a direct and annual tax, meaning it is calculated based on property ownership and must be paid annually, regardless of whether the property is rented out or not. It's important to note that IBI is governed by the Law Regulating Local Finances (Law 39/1988).

What taxes are paid on a property?

When acquiring a property in Spain, owners may be subject to several taxes, including:

  1. Property Tax (IBI): as mentioned, this is paid annually and is based on the cadastral value of the property.
  2. Personal Income Tax (IRPF): for those who rent out their property, the income earned must be declared in their IRPF tax return.
  3. Property Transfer Tax (ITP): this tax is paid when a property is purchased, and it varies depending on the autonomous community.
  4. Tax on the Increase in Value of Urban Land (Plusvalía): this tax is paid at the time of property transfer, and its value depends on the increase in the land's value during the period it was owned by the seller.
  5. Inheritance and Gift Tax: if a property is acquired through inheritance or donation, it is subject to this tax.

How much is property tax?

The amount payable as IBI varies considerably depending on the property's location and characteristics. It is paid annually and varies by municipality, as it depends on the cadastral value of the property and the tax rates set by local councils. It is governed by the Law Regulating Local Finances and established through fiscal ordinances. It ranges between 0.4% and 1.1% of the cadastral value for urban properties, and 0.3% and 0.9% for rural properties.

For example, if a property has a cadastral value of 100,000 euros and the tax rate is 0.5%, the IBI payable would be:

100,000 x 0.5% = 500 euros payable

How is property tax calculated?

The IBI calculation is performed once a year, taking into account the following steps:

  1. Determination of the cadastral value: an administrative value set by the State, through the Cadastre, and cannot exceed the market value of the property; it is updated every ten years, taking into account factors such as location, surface area, age, and characteristics of the property
  2. Application of the tax rates set by the corresponding local council. This refers to the deductions (levies) that the owner may be eligible for, depending on the municipality where it is located. It is important for owners to consult with their respective local council to find out the tax rate applied to their specific property.

In some cases, owners may benefit from exemptions or reductions in the IBI. For example, certain local councils offer incentives for social housing, as well as reductions for the installation of systems of energy efficiency. In general, provisions for exemptions and bonuses vary according to municipal legislation.

Property owners are advised to carefully review their IBI bill each year to ensure the calculation is correct and that cadastral data is up-to-date.

Who must pay property tax?

IBI must be paid by all owners of urban, rural, or special properties. This includes both individuals and legal entities (companies). In cases of shared ownership, the tax will be proportional to each owner's share of the property.

If the owner has a legal relationship with surface rights holders, concessionaires, or usufructuaries, these are the ones obligated to pay this tax, not the owner.

Regarding rentals, it is the owner who must pay the IBI, not the tenant.

If a property is sold mid-year, for example, the property tax must be paid by whoever is the owner of that property as of January 1st of that year. When carrying out a property sale transaction, it is recommended to check that there are no unpaid annual payments, as these could become the responsibility of the new owner.

How is IBI paid?

IBI can be paid in different ways, depending on the regulations of each municipality. Generally, there are two payment methods:

Voluntary payment period

Bills are usually sent to property owners at the beginning of the year, with the option to pay them in a single installment or in fractional payments, as permitted by the city council.

Enforcement payment period

If the owner fails to pay within the stipulated period, the city council can initiate proceedings to seize assets or bank accounts.

Payments can be made at authorized financial institutions, at city council offices, or through online platforms, depending on what each municipality offers.

Examples of property tax

To illustrate the impact of IBI, let's consider two scenarios:

  1. Urban apartment owner: let's assume María owns an apartment in Madrid with a cadastral value of 150,000 euros. If the tax rate is 0.6%, the IBI payable will be: 150,000 x 0.6% = 900 euros
  2. Rural property owner: in this case, we assume Juan owns an agricultural property in a rural area, with a cadastral value of 50,000 euros and a tax rate of 0.4%. Thus, the IBI will be: 50,000 x 0.4% = 200 euros

These examples demonstrate how the tax rate and cadastral value directly influence the amount payable.

What to do if I cannot pay property taxes?

Remember that IBI is a mandatory tax that must be paid. Failure to pay can result in surcharges or seizures for the property owner and financial problems for the city council.

If an owner finds themselves unable to pay the tax, it is crucial to act immediately. They can request a payment deferral or installment plan; many city councils offer options for advance payment or payment in installments to help owners fulfill their obligation.

It is important to know that, sometimes, by explaining their financial difficulties , city councils may consider the owner's financial situation and allow for temporary exemption or reduction of the IBI.

As a last resort, in extreme cases, consider seeking legal advice; this involves contacting a lawyer or tax advisor who can offer guidance on the available options.

Are there properties that don't pay IBI?

Yes, there are exceptions to the obligation to pay IBI. According to regulations, some examples include:

  1. Publicly owned properties: properties belonging to state, regional, or local entities are exempt from paying IBI.
  2. Properties used for religious activities: many temples and churches are exempt from IBI.
  3. Properties of non-profit organizations: those dedicated to social activities can benefit from certain exemptions.

It is important to consult the specific regulations of each municipality to determine if a property could be exempt from IBI.
