The instructions together with all the details here.

5- How to fill in the Excel template for all assets abroad?

  • S-type well: Life or disability insurance and temporary or life annuities, the insurers of which are located abroad.
  • Good type B: Ownership and rights in rem over real estate located abroad.

6- How do I obtain the statement from foreign brokers?

You can see how to download your portfolio for DeGiro, IBKR, Revolut, XTB, eToro, Charles Schwab and Trading 212 among others.  here.

7- Can I generate the Form 720 for portfolios of several brokers?

Yes, to do so, compress in .ZIP format the files of the brokers for which you want to obtain the completed Form 720.

8- Can I change the default values that are made during the automation of the Model 720 (number of owners / marital assets and Country of the broker)?

Yes, you can change the NUMBER OF OWNERS / PROFITABLE PROPERTY and COUNTRY CODE (in the "Declarant details" section) of the Form 720 when you fill it in with Autodeclaro.

This is very useful when we want to indicate that we are two or more owners or simply the owner is one but we are in community of property so the ownership is assigned to the 50% (in the case of 2 owners).

To do so, this information must be added to the .CSV file name, and then compress the file(s) into a .ZIP file the archive(s).

  • [NUM_HOLDERS]_[COUNTRY]_rest filename.CSV

Examples of valid filenames:

  • 1 Italian headline and broker: "1_IT_myPortfolio.csv".
  • 2 headlines and French broker: "2_FR_myPortfolio.csv".
  • 3 holders (default broker country. See previous question): "3_myPortfolio.csv".

Then compress the file(s) in a .ZIP file. This ZIP file can have any name.

Autodeclaro will assign the ownership percentage according to the number of owners or will change the country of the default tax domicile that the broker has in Autodeclaro for the indicated file in case it has been indicated.

Note: Don't forget that if you use these prefixes, compress the file in ZIP.

9- What happens if the security/share has changed ISIN since the last filing of the Form 720?

E.g. Let's say a security had the ISIN: EN222 in 2021 and changes to EN999 during the year 2022.

If this value/share was not declared in the last Model 720 (from 2021), nothing happens. It is declared as type of origin of the asset A (First filing).

However, you declared in the last Modelo 720 (from 2021) the ISIN: ES222 and you keep the value with the new ISIN ES999 that you have to declare in a new Modelo 720, Autodeclaro will do the following:

  • Registration of type of origin of asset C: for ES222. In other words, the ownership of that asset is extinguished for ISIN ES222.
  • Source type record of asset A: for ES999. That is, this asset is declared for the first time for ISIN ES999.
10- What about securities such as options, futures, CFDs and forex?

Autodeclaro filters out options, futures, CFDs and currencies as they are not declared in the 720 Model, as explained in this binding consultation V0813-17 are derivative financial instruments and are not considered to be securities or rights representing interests in legal entities.

Therefore, even if they appear on the statement provided by your broker, you do not have to delete them, we take care of it.

11- I am using leverage/borrowed money from my broker.

It is a loan, and as such is not declared in the 720 model. The shares held in your broker are declared as such, whether or not there is leverage.

12- When is the CSV, Excel or ZIP file attached to generate the Form 720?

Before finalising the purchase you will have the possibility to attach the excel file or also with the share portfolio in order to generate your Modelo 720.
Once the process is complete, you will receive your completed Model 720 in BOM 720 format, ready for you to be imported into the state tax agency's or provincial/county's tax office's income tax web programme.

13- What exchange rate is used for positions whose currency is not the EURO?

The exchange rates used are those of the ECB (European Central Bank) at the date of 29 December 2023(last working day and with published exchange rates).

They are the same as those published in the BOE  as of 29 December 2023.

Note RUB (Russia): ECB and BOE fix exchange rate EUR/RUB.

  • For the RUB, the ECB does not fix it from 1 March 2022.
  • For this reason, we have decided to fix the EUR/RUB exchange rate marked by XE.COM e providing the same exchange rate for 29 December 2023 (last working day and with published field rates)

Note DeGiro: Although DeGiro provides the position statement in Euros, it is not using the ECB exchange rate, so the values in Euros may be different between those indicated by DeGiro and those that Autodeclaro calculates and fills in the Form 720.

14- What values are indicated by default (% participation, origin of the asset or right, country code...) in the Model 720 during automation?


    • By default, a single holder is indicated, i.e. a 100% holding is reflected in the Form 720. In this case each extract corresponds to a single holder.
    • It can be changed as indicated in the question 8 "Can I change the default values that are made during the automation of the Model 720 (number of holders and Country of the broker)"?


    • By default always A shall be indicated A (Asset or right being declared for the first time or incorporated in the declaration exercise).
    • It shall indicate M (Asset or right that has already been declared in a previous financial year)
    • It shall indicate C (Property or right that is declared because the title or any other form of real ownership over it is extinguished).

In order to be able to indicate M or C values, the extract of the last financial year of the Form 720 filed must be included, more details here.

There are new developments in the 2024 campaign regarding how to indicate the completion of the "Origin of the Asset or Right" explained in the Question 2- What's New 2024

COUNTRY CODE (In section "Data of the declarant"):

  • The custodian country of the broker shall be indicated. The following default country correlation is assigned by default for each broker.
  • It can be changed as indicated in the question 8 "Can I change the default values that are made during the automation of the Model 720 (number of holders and Country of the broker)"?

But it could be changed as indicated in the next question.

    • DeGiro : NL (The Netherlands)
    • IBKR : IE (Ireland)
    • Revolut : GB (Great Britain)
    • XTB: The country indicated in the extract
    • eToro: CY (Cyprus)
    • Trading 212: CY (Cyprus)

    • DIF Broker: PT (Portugal)
    • Scalable Capital: DE (Germany)

COUNTRY CODE (Under "Address of the entity or location of the property):

    • This is the Páis of the address of the entity's registered office in its tax domicile. We have a data source of 70k companies obtained from "".
    • In the event that such an address is not found, this value shall be left empty and must be complied with.

ADDRESS (Other fields)


    • For brokers' statements, only goods shall apply:
      • Type V (Securities or rights representing participation in any type of legal entity) and
      • Type I (Shares and units in Collective Investment Schemes located abroad)
    • They also apply to brokers the type C (Accounts opened in entities engaged in banking and credit transactions and located abroad) and must indicate in the web income programme the money deposited in cash with brokers abroad. If you were in an Investment Fund, the following would apply Type I. Note: There are no bank account details in the broker's statement..
SUBCLAVE TYPE OF PROPERTY OR RIGHT (Disabled for I, only indicated for V)
      • 1- Securities or rights representing participation in any type of legal entity.
      • 2- Securities representing the transfer of own capital to third parties.
      • 3- Securities contributed for management or administration to any legal arrangement, including trusts and trusteeships or bodies of property which, although lacking legal personality, may act in the course of trade.
Default values for asset type V and I, together with its subkey if V.
      • Actions: Type V subkey -> 1
      • ETFs and Mutual Funds: Type I. (No subkey applicable)
      • Bonds, ETCs and ETNs: Type V subkey -> 2
15- Does the result of the total of Model 720 in the tax authorities not match the total of my portfolio?

This occurs when we are declaring extinguished or sold records (origin of type C asset).

The sum of the total of model 720 adds up all the records of type A (new incorporation), M (asset already declared) and C (extinguished / sold), so your portfolio value shown by your broker is not the same as the one shown in the model 720 in the tax office.

16- How is the broker's cash/balance declared?

If you wish to declare cash/broker's balance, you have to do so if it exceeds €50,000. Remember that it is a separate block from listed shares/securities, so it is counted separately.

In the instructions explains how.

17- Do you have to file a Form 720 for a past campaign?

If it is not the first time that you have filed Form 720, you must include the extract of the last financial year filed together with that of the financial year you wish to file.

If, for example, you last filed in the financial year 2020, and you wish to file for the financial year 2022, you must provide the statement for 2020 and the statement for 2022 as at 31 December in both cases.
