Cryptocurrencies can be defined as a digital exchangeable asset that uses cryptographic methods to secure its financial transactions, control the creation of new units and verify the transfer of assets.
They are considered, for tax purposes, as intangible assets, which are computed by units or fractions of units. Although they are not legal tender, they are used as a means of payment as they can be exchanged for other goods, including other virtual currencies.
In recent years, interest in investing in cryptocurrencies has grown as a result of a combination of technological, economic, social and cultural factors. It is a phenomenon that is constantly evolving, and the adoption of cryptocurrencies seems to be on an upward trend due to innovation in the sector and the growing interest in alternatives to the traditional financial system.
For this reason we believe it is important to understand the fiscal effects and obligations to which we are exposed when using and owning cryptocurrencies.
The yield and holding of cryptocurrencies must be declared from April until June, by filing form 100 and form 714.
There is no minimum amount; you are always obliged to declare the result of your investments in cryptocurrencies.
From the 1st of January until the 31st of March, all residents in Spain, both individuals and legal entities, are obliged to declare their holdings of cryptocurrencies abroad if the accumulated balance exceeds €50,000.
The declaration is made using Form 721 of the Informative Declaration on virtual currencies located abroad, which must include precise information on the cryptocurrencies held and be filed between January and March of the following year.
Losses obtained by holding cryptocurrencies are also declared for income tax purposes.

The result of the transactions carried out with cryptocurrencies must be declared for income tax (IRPF) and the holding of cryptocurrencies for Wealth Tax (IP).
Transactions made with virtual currencies will give rise to a capital gain or loss. This is generated by the difference between the price at which the cryptocurrency is acquired and the price at which it is sold or exchanged. Therefore, the result must be determined for each particular transaction by calculating the difference between the sale price in euros (unless this is lower than the market value) and the amount at which the said currency was acquired. Expenses and taxes directly related to these transactions may be considered.
All units of the same cryptocurrency are equal to each other, which means that they cannot be differentiated from each other. Therefore, when a sale is made of cryptocurrencies that have been purchased at different times and at different prices, the FIFO ("First In, First Out") rule is used. This means that, in order to calculate the result of the transaction, the first coins purchased are considered to be sold.
By means of example, if you have cryptocurrency type A according to the following table.
DATE |
UNITS |
VALUE |
TOTAL |
05/09/2022 |
5 |
€10,000.00 |
€50,000.00 |
15/11/2022 |
2 |
€12,500.00 |
€25,000.00 |
23/03/2023 |
3 |
€11,350.00 |
€34,050.00 |
And on the 25th of November 2023, 6 cryptocurrencies (A) are sold at a value of €14,250.00 each.
The total sales price would be €85,500 and for the calculation of the cost we must first consider the oldest units.
Meaning that we will have:
5x10.000€ = 50.000€
1x12.500€ = 12.500€
Total cost = 62.500€.
To calculate the capital gain the sum would be €85,500 - €62,500 obtaining, therefore, a gain of €23,000. From this capital gain we can deduct the expenses that are directly attributable to the transactions carried out.
As such, we have determined a capital gain that, according to the provisions of Law 35/2006, of the 28th of November, on Personal Income Tax (IRPF) (Ley 35/2006, de 28 de noviembre, del Impuesto sobre la Renta de las Personas Físicas (IRPF)), must be included in the income tax return.
According to article 14 of the Personal Income Tax Law, this gain will occur at the moment in which the virtual coins are delivered, regardless of the moment in which the sale price is received.
In our example we can consider the sale to have been made in November 2023, so we must include this capital gain in our income tax liquidation for 2023.
It remains for us to determine what type of income constitutes the capital gains and losses derived from the transfer of virtual currencies.
According to article 46 of the Personal Income Tax Law, the amount of capital gains or losses derived from the transfer of virtual currencies constitutes savings income and must be included in the income tax return in the specific section for cryptocurrencies.
Since it is savings income, the following percentages will be applied.
Cryptocurrencies are considered intangible assets and are part of personal wealth. If the total assets exceeds the limits established by the regulations, cryptocurrencies must be included in the declaration of wealth.
In case your total wealth, including cryptocurrencies, exceeds the established limits, you must file this form, including cryptocurrencies in the section "Other assets and rights of economic content" ("Otros bienes y derechos de contenido económico").
That is to say, in the Wealth Tax Form 714, cryptocurrencies are declared in the section of "Other assets and rights of economic content". There is no specific section in this form.
In order to calculate the value in euros of the cryptocurrencies to be included in Form 714 (IP), the price of these on the 31st of December will be taken. If no price is found, the acquisition value will be taken.
If the total value of your cryptocurrencies abroad exceeds 50,000 euros, file Form 721 between the 1st of January and the 31st of March of the year following the fiscal year to be declared.

Penalties for not declaring cryptocurrencies can be severe:
There are several laws and regulations that seek to balance technological innovation with consumer protection and the integrity of the financial system, as well as to prevent money laundering and terrorist financing through the use of virtual currencies.
The main laws and relevant articles are detailed below:
