Complete Guide on Taxes and Legal Obligations for Renting an Apartment in Barcelona (2025)

Renting an apartment in Barcelona involves a series of tax and legal obligations that property owners must know to avoid penalties and optimize profitability. In 2025, regulations have undergone significant changes, especially in high-demand areas and applicable tax deductions. Below, we analyze the key taxes and obligations to consider for managing a rental efficiently and legally.

Applicable Taxes for Renting

Personal Income Tax (IRPF)

Income from rental properties must be declared as real estate capital income in the income tax return. Deductions apply based on rental conditions:

• 50%: For general contracts.
• 70%: If the tenant is between 18 and 35 years old or in a vulnerable situation.
• 90%: If the property is in a high-demand area and the rent is at least 5% lower than the previous contract.
  If net income after deductions exceeds €1,600 annually, filing a tax return is mandatory. Deductible expenses include home insurance, community fees, mortgage interest, and necessary repairs for property maintenance.

Property Tax (IBI)

IBI is a municipal tax paid by the property owner. However, the lease agreement may specify that the tenant covers this cost. The amount varies depending on the municipality and the property’s cadastral value.

Value-Added Tax (VAT)

• Exempt: For residential leases.
• 21% VAT: Applies to tourist rentals or mixed-use properties (e.g., office and residence).
  If the landlord provides additional services typical of hotel operations (e.g., cleaning, linen changes, reception), VAT must also be charged.

Tax Obligations for Non-Residents

Non-resident property owners must file the Non-Resident Income Tax Return, applying fixed rates to income generated in Spain. Depending on the owner’s country of residence, a double taxation agreement may prevent double taxation.

Legal Obligations for Property Owners

Contract Registration and Transparency

Rental contracts must include:

• The price of the last contract within the past five years or the reference from the national price index.
• Declaration if the owner is a large property owner (owns five or more properties).
  Failure to meet these requirements may result in fines ranging from €9,001 to €900,000. Additionally, landlords must ensure that contracts comply with the Spanish Urban Leasing Law (LAU).

Rent Limits in High-Demand Areas

In Barcelona, properties in high-demand areas must meet the following requirements:

• Rent cannot exceed 95% of the reference index.
• Exception: Properties over 150 m² or recently renovated properties may increase the rent by up to 10%.
  Owners can check if their property is located in a high-demand area through the Barcelona City Council portal.

Repairs and Maintenance

The owner must ensure the property is habitable and address urgent repairs (e.g., leaks, electrical problems, heating). Additionally, the landlord must provide a contact for incidents and conduct periodic inspections to prevent serious deterioration.

Mandatory Documentation

• Energy performance certificate.
• Certificate of occupancy.
• Security deposit registration with INCASOL.
  Failure to register the deposit may result in administrative penalties.

Relevant Penalties in 2025

Violations may result in significant penalties:

• Rent Limit Exceedance: Fines up to €900,000.
• Abusive Clauses: Charging more than two months’ rent as a deposit or passing on costs like IBI or structural repairs to the tenant—fines up to €90,000.
• Deadline Non-Compliance: Contract adaptations to new regulations must be completed within five days of publication.
  Additional penalties may apply if the property is rented without mandatory documentation or if ownership changes are not properly communicated.
