Instructions for Form 720
Note: Autodeclaro is not a consultancy, nor are we tax experts. We simply automate the completion of the Form 720 from the files you provide using the Excel template, statements from your broker or crowdlending platforms, accounts and deposits such as Raisin.
We are not responsible for your use of the information described here. It is your responsibility to check the information or instructions given here with a tax advisor.
You are ultimately and solely responsible for your declaration.
Once we have received our completed Form 720, the next step is to import the file generated in the tax office.
If you don't have it yet, you can generate it at:
The table of contents of this article is:
- Review of marital status and property regime (community property or separation)
- Import and file with the Tax Agency, the Provincial Councils of Guipúzcoa, Vizcaya and Álava, and the Treasury of Navarre.
- Declare cash account (DeGiro, IBKR, XTB and Trade Republic)
Marital status and property regime (community property or separation)
If married in community of property, the spouse would have to complete Form 720.
In Autodeclaro we offer the generation of the 720 model for your spouse at no additional cost, you just have to check the option that you are married in community of property and you need the 720 model for your spouse. This is indicated in the final purchase process.
The obligation of the spouse to report in the Model 720 is explained in the questions frequent use of the AEAT Form 720. And the answer is:
“When the formal ownership of a community property or right belongs to one of the spouses, both spouses (if they are within the subjective scope of the obligation) are obliged to file the declaration.
The spouse who is not the formal holder must declare as the beneficial owner in accordance with Article 4.2 of Law 10/2010 of 28 April 2010 on the prevention of money laundering and terrorist financing.“
Situations that married couples may encounter
1/ Married in separation of propertyEach one presents and reports his or her assets regardless of what the spouse disposes of.
2/ Married in community of property: The spouse owning the assets reports to 100% and the spouse not owning the assets to 50% as above. Autodeclaro generates this file automatically in the order. But there can be two situations
a/ Sole spouse has property abroadThe holder reports to 100% and the non-holder spouse to 50%. A single request is sufficient to inform both the holder and the non-holder.. In the order you will receive a file for each one where you will file directly with the tax office following the instructions
b/ Both spouses own property abroad: In this case, two situations arise
- The holder informs the 100% of his or her assets and the non-holder spouse informs the 50% of those assets.
- And vice versa, the other entitled spouse reports to 100% on his/her assets and the non-entitled spouse reports to 50% on those assets.
In this case two orders would be necessary, one for each holder with the assets he owns. In the order you will receive your assets at 100% ownership and 50% in community of property for the couple.
Submission process for case 2b - Both spouses own property abroad.
Two orders have been placed:
- Order spouse 1720 file extension is obtained with the model 720 of the holder (spouse 1) and also in community of property for the couple (spouse 2).
- Spouse order 2Vice versa, file extension .720 is obtained with the model 720 of the holder (spouse 2) and also in community of property for the partner (spouse 1).
In the example, we are spouse 1
1/ The received file with extension .720 indicating in ganancials (from the order) will be imported. spouse 2) is imported (step 2 of the capture) after filling in the ID card (step 1 of the catch). Full instructions here.
2/ Fill in the personal details of the spouse 1 .
3/ Export (step 3 of the capture) so that the .720 WIN file received in the order spouse 2 have the DNI and full name of the spouse 1.

We now have two files with extension .720
- Form 720 generated during the purchase in the order for the spouse 1
- Form 720 in community of property exported in the previous order step spouse 2 with the personal data of the spouse 1
4/ Import the first file “Modelo 720 generated in the order of the spouse 1”following the instructions: Choose option A - delete declaration and import)
5/ Import the Model 720 in community of property that has been prepared in step 3 with the DNI of spouse 1 and personal data (Choose option B - Add records to the current one.)

Records type "Origin of the good or right" type "C".
Update: 15 January 2025. Autodeclaro automates the filling in of the value and date of sale from the transactions offered by brokers. DeGiro, IBKR and Revolut how we do for the service of Auto-Renta.
If you have a lot of type C (extinguished) records to complete, please review the instructions for brokers on the Form 720. DeGiro, IBKR and Revolut.
If you have type "C" recordsare extinguished securities (they were declared in your previous Model 720 declaration but you no longer hold them in your portfolio). The valuation indicated by Autodeclaro is 0, so that It would be advisable to update this with the sale value and the date of sale/discontinuation.
Note: Sales during the year of purchases that have occurred in the same year are not reported on form 720.
You can quickly identify the type C records to be reviewed through the summary CSV you receive in the confirmation email.
Note: if you use crowdlending as Mintos or ViaInvest you may have hundreds of type C records. In that case the platform indicates all these records as closing date 31 December of the reporting year.
Check that type C records have valuation and date of sale indicated:

Below is indicated in yellow where to fill it in once it has been imported in the AEAT:
- Sales AmountIn the field "Valuation 1" : In the field "Valuation 1" : In the field "Valuation 2
- If the sale is in a currency other than the Euro, you can make the conversion using the exchange rates indicated by the European Central Bank for that day of the sale.
- Date of saleIn the field "Date of expiry".

In addition, these records of type "C" being extinct valuesappear totalled to the total value of the Model 720.
In other words appear in the sum of the total value that appears in the AEAT's Form 720, is greater than its value on 31 December, as indicated by the broker.
E.g. In the example below, there is a type C record for a value of 49,106.13 euros, and it is added to the total shown in the summary of the 720 tax return at the AEAT.


If we have securities that have suffered a spin-off that we declared in a previous Form 720 and we sell them during the following year, these will appear as a type "C" record. You will have to indicate the amount and date of the sale of the company resulting from the spin-off, which was declared in the previous Form 720 that you have filed in the current year.
Note: To see the day when the ISIN that appears in the C-type registers ceased to trade, here are a couple of tips:
- Web https://es.marketscreener.com/ to search for the ISIN and see the last day and amount of trading, for example: https://es.marketscreener.com/ quote/stock/share/DESKTOP-METAL-INC-131564025/
- Web https://extraetf.com to look up the ISIN and see the last day and amount of trading, for example: https://extraetf.com/es/stock-profile/US00165C2035?tab=chart
- The website is also valid justetf.com it is often interesting to look up the ISIN you have without amount and date, as in the example I show: https://www.justetf.com/en/stock-profiles/US09247X1019#chart searching for the ISIN and usually gives the company's last share price and the date when it has been a spin-off or change of isin the reason for the “C” type registration.
