It’s that time of year again to discuss Modelo 720, and it seems like every year, many new members on the forum are asking about it. As someone who has filed it a few times, I want to share what I’ve learned, especially regarding overseas real estate, as that seems to be the biggest concern for everyone. If I get anything wrong, I welcome corrections from the seasoned folks here!
The main question is: Who needs to file? Simply put, for the [overseas asset declaration], if you are a tax resident in Spain and the total value of your assets in a single category abroad exceeds €50,000, then you need to file [Modelo 720]. Note that this is calculated per category. For example, if the total deposits in all your overseas bank accounts exceed €50,000, or the combined value of all your properties exceeds €50,000, you must file. If you have filed previously, you only need to file again if the value of your assets has increased by more than €20,000.

How to Value Overseas Property?
This is a key point and can be tricky. The tax authorities stipulate that the value of a property is typically based on its “acquisition cost,” which is how much you paid for it. If you own multiple properties, you add up their acquisition costs to see if the total exceeds the €50,000 threshold. For inherited or gifted properties, the situation is more complex; you generally need to refer to the value recorded on the official documents at the time of inheritance or gift. My personal advice is to keep all related contracts and receipts safe, just in case.
Key Information for Declaration
When declaring property, you need to provide very specific information. I’ve put together a simple table so you can see what materials you’ll need to prepare:
| Information Category | Specific Details |
| Identification | The full address of the property, including country, city, street, and building number. |
| Property Type | Is it a residence, commercial space, or land? |
| Ownership | Do you own it 100%, or is it jointly owned? If co-owned, specify your share. |
| Acquisition Date | The date on the purchase contract or property deed. |
| Value | Fill in according to the “acquisition cost” as mentioned above. |
One last reminder: the filing period for Modelo 720 is typically from January 1st to March 31st each year. Although the penalties for this form are not as severe as they used to be, failing to file or filing incorrectly can still lead to trouble. If your situation with [overseas real estate investment] is complex—for example, you have multiple asset types or co-owned properties—it’s highly recommended to hire a reliable Gestor to handle it. Spending a little money can save you a lot of hassle and risk. After all, it’s best to leave professional matters to the professionals.
