Important: This article was published in 2018 and analyzes the Preliminary Draft Law on Measures to Prevent and Combat Tax Fraud in relation to virtual currencies. The subject matter analyzed was subsequently incorporated into the legal system through Law 11/2021, of July 9, and implemented through new reporting requirements regarding virtual currencies.
Virtual Currencies and the Tax Agency. Taxation
On October 23, 2018, the DRAFT BILL ON MEASURES TO PREVENT AND COMBAT TAX FRAUD was published for the purposes of the public information procedure, directly affecting Virtual Currencies and the Tax Agency.
In fact, among the measures contained in the aforementioned PRELIMINARY DRAFT BILL are those relating to the regulation of cryptocurrencies—whether held in Spain or abroad—for taxpayers subject to the Spanish tax authorities. This regulation aims to obtain information on the balances and holders of virtual currencies held in custody and establishes an obligation to provide information on cryptocurrency transactions.
In particular, this draft bill would entail—especially—the following amendments:
1. Introduction of new sections 6 and 7 in the Thirteenth Additional Provision of Law 35/2006, of November 28, on Individual Income Tax and partially amending the laws on corporate income tax, on Nonresident Income Tax , and Wealth Tax
2. The amendment to paragraphs 1 and 2 of the EIGHTEENTH ADDITIONAL PROVISION of Law 58/2003, of December 17, on General Taxation.
Objectives: Oversight of Transactions Involving Virtual Currencies and Cryptocurrencies. Taxation and Anti-Money Laundering
As stated in the Explanatory Memorandum of the Draft Bill, among other measures it includes, it seeks to strengthen “tax control” over the potential taxation related to virtual currencies. To this end, two measures are essentially reinforced:
1.- Information measures relating to: the balances held by holders of virtual currencies; as well as information about transactions (acquisition, transfer, exchange, transfer, receipts and payments).
2.- Penalty measures
Subjects: Exchanges, Technology Service Providers, and Taxpayers
The objectives of such regulation affect:
1.- Companies providing services related to Cryptocurrencies. This regulation covers
a.- Individuals/entities resident in Spain
b.- Permanent Establishments in Spain
c.- Entities resident abroad
That primarily provide the following services:
a.- Safekeeping of private cryptographic keys on behalf of third parties, to hold, store and transfer virtual currencies;
b.- Exchange between virtual currencies and legal tender or between different virtual currencies, or acting as an intermediary in any way in carrying out such transactions.
2.- Taxpayers (tax obligors)
In summary, we should bear in mind:
Prestadores de Servicios
Los prestadores de servicios son definidos como las personas y entidades residentes en España y los establecimientos permanentes en territorio español de personas o entidades residentes en el extranjero.
Obligados Tributarios
Los obligados tributarios son los contribuyentes, personas físicas o jurídicas, sometidos a la Hacienda española.
Servicios de Intermediación
La intermediación es una de las categorías de servicios definidas legalmente, por la que sus prestadores, independientemente de la forma en la que intermedien en la realización de operaciones de adquisición, transmisión, permuta, transferencia, cobros y pagos de monedas virtuales.
Servicios de Claves
Los prestadores de servicios de claves criptográficas privadas en nombre de terceros, para mantener, almacenar y transferir monedas virtuales, también se encuentran dentro de los sujetos obligados a prestar información a la Agencia Tributaria.
Servicios de Cambio
Los prestadores de servicios de cambio entre monedas virtuales y dinero de curso legal o entre diferentes monedas virtuales quedan igualmente sujetos a las obligaciones informativas. Los servicios de intermediación y cambio se encuentran íntimamente ligados, aunque la norma los haya definido específicamente.
Consequently, a more intense and focused interrelationship between Virtual Currencies and the Tax Agency begins, which will result not only in the corresponding amendment of the regulations but also in forthcoming implementing regulations to make it effective.
