If you live in Spain as a tax resident and you own a holding in an Estonian company, Modelo 720 probably concerns you — the Spanish annual declaration of assets held abroad. It is not a tax. You pay nothing for it. It is simply information for the Spanish tax authority about what you hold abroad.
But if you complete it wrongly or leave it unfiled, it draws the tax authority's attention to you.
Where your Estonian holding belongs
Modelo 720 divides foreign assets into three blocks. Each block has its own 50,000 euro threshold, measured as at 31 December:
- bank accounts (art. 42 bis),
- securities and holdings in companies (art. 42 ter),
- real estate (art. 54 bis).
Your holding in an Estonian company goes into the securities block (art. 42 ter). You declare it only once the total value of the assets in that block passes 50,000 euros.
How much your holding is worth on paper
This is where most mistakes are made. The value to be declared is not the 2,500 euros you paid in as share capital when you set the company up. It is your share of the company's theoretical value according to the last approved balance sheet (valor teórico del último balance aprobado).
That means one important thing for every owner of an Estonian company: retained profit raises the value you have to declare. If you leave the profit inside the company, the equity grows and your value grows with it — even if you have not taken out a single cent.
Why this starts with Estonian bookkeeping
For that you need a proper balance sheet as at 31 December, ready on time. Estonian law places this duty on the management board.
Commercial Code § 179 subsection 1: "After the end of the financial year, the management board prepares the annual report pursuant to the procedure provided in the Accounting Act."

If the Estonian bookkeeping runs late or the annual report is left unfiled, the Spanish declaration inherits the same problem. If this is your situation, start here: A late annual report.
The deadline
Modelo 720 is filed for the previous year between 1 January and 31 March. The calm option: ask for the Estonian figures in January and file in Spain in March.
Fines — without the old horror stories
The old penalty regime for Modelo 720 was notorious. The European Court of Justice struck it down on 27 January 2022. The Court held it to be disproportionate. Spain then changed the rules by Ley 5/2022. The general penalty regime now applies (art. 198–199 of the Spanish General Tax Act):
"…la sanción consistirá en multa pecuniaria fija de 20 euros por cada dato… con un mínimo de 300 euros y un máximo de 20.000 euros."
That is, 20 euros for each missing item of data, at least 300 and at most 20,000 euros. If you file late on your own initiative, before the tax authority asks, the fine is reduced by half. The greatest risk today is not the fine. The greatest risk is that an incomplete declaration makes the tax authority look at you more closely.
Frequently asked questions
Is Modelo 720 a tax?
No. It is information only. Tax arises on income — on dividends in your Spanish income tax return, for example, not here.
My holding is below 50,000 euros. Do I have to file anything?
If the total value of the securities block stays below 50,000 euros and you have not declared that block before, then no. Keep the year-end value on record all the same — retained profit changes that figure every year.
