Spain is one of the most popular destinations for foreigners buying property, whether as a second home, holiday residence or investment. However, many non-resident owners are unaware of a key tax obligation: the annual Non-Resident Income Tax (IRNR) return in Spain.
This tax applies to all foreign property owners in Spain, even if the property is not rented out. Failure to comply can result in penalties, interest, surcharges and, in serious cases, asset seizures or charges recorded in the Land Registry.
In this guide, we explain clearly what IRNR in Spain is, who must file it, how to avoid problems and why it is particularly important for German property owners in Spain.
What Is IRNR in Spain?
The Non-Resident Income Tax (IRNR – Impuesto sobre la Renta de No Residentes) must be filed by individuals who:
- Are not tax residents in Spain
- Own property in Spain (house, apartment or commercial premises)
- Whether or not they generate rental income
This tax return must be filed every year, even if:
- The property is not rented
- It is used only for holidays
- It remains empty
In these cases, the Spanish tax authorities apply an imputed income, meaning a notional income based on property ownership.
What If I Rent Out My Property?
If the property is rented, either partially or fully, the rental income must be declared under IRNR.
EU residents (including Germany) can deduct expenses related to the rental, such as property tax, community fees, repairs, mortgage interest, utilities and insurance.
Non-EU residents cannot deduct expenses.
Rental income must be declared quarterly.
What Happens If You Do Not File IRNR?
The Spanish Tax Agency has access to extensive financial and property data and increasingly exchanges information with European countries, including Germany.
If a non-resident fails to declare:
- A tax notice is sent to the address registered in the Land Registry or to the country of residence
- If no response is given within 10 working days, a provisional tax assessment is issued including penalties and interest
- If unpaid, the assessment becomes final
The authorities may then initiate enforcement actions, including:
- Seizure of Spanish bank accounts
- Offsetting future tax refunds
- Registering the debt against the property in the Land Registry
If the property is later sold, inherited or donated, all outstanding debts must be settled, including surcharges.
For this reason, filing IRNR correctly each year is essential.
Important Information for German Property Owners in Spain
German citizens represent one of the largest groups of foreign property owners in Spain, particularly in regions such as Andalusia, the Balearic Islands, Valencia and the Canary Islands.
If your tax residence is in Germany, you are required to file IRNR in Spain, even if you spend time in Spain during the year.
Many German owners are unaware of this obligation, especially when the property is not rented. Spanish taxes are not included in the German tax return (Steuererklärung), so failing to declare in Spain results in non-compliance.
Spain and Germany exchange financial and tax information automatically. This includes bank accounts, property ownership and income. Both tax authorities have access to the same data.
In many cases, German property owners only become aware of unpaid IRNR when attempting to sell their property, as a tax charge appears registered against it.
How Is IRNR Calculated If the Property Is Not Rented?
The calculation is based on:
- The cadastral value of the property
- The number of owners
- The period during which the property was available
- The applicable tax rate (19% for EU residents)
In most cases, this is a relatively low tax when declared correctly and on time.
Why You Should Hire a Specialist Tax Advisor for Non-Residents
A specialised advisor ensures:
- Correct and timely filing of tax returns
- Proper declaration of rental and imputed income
- Avoidance of penalties and enforcement actions
- Monitoring of tax notifications
- Representation before the Spanish Tax Agency
For German clients, it is particularly useful to work with a professional familiar with Spanish tax law, the Spain–Germany tax treaty and the relevant tax forms, including Modelo 210, 211, 216 and 115.
Conclusion
Non-Resident Income Tax (IRNR) is a mandatory obligation for all foreign property owners in Spain. While the tax itself is usually modest, failing to comply can lead to significant financial and legal consequences.
Filing correctly and on time is essential. Professional advice ensures compliance and peace of mind.
