In 2008, a developer – known only under the pseudonym “Satoshi Nakamoto” – published the first whitepaper for the crypto-currency “Bitcoin”, which has proven to be a highly volatile investment for currency speculators. The first currency-token is based on the blockchain – a distributed ledger technology.
On 18 September 2019, the previous German Federal Government had presented its block-chain-strategy. Whether the underlying technology might be “The next big thing” or the marketability is overestimated due to “empty promises of ‘techies’ for unsolved problems” can be hardly answered. It is certain that the research and development potential is still immense.
Due to the technical complexity there is a legislative backlog for the legal classification of blockchain-based business models. The conclusion for taxation purposes of the literature are based on the subsumption of tax-relevant processes under the German Tax Codes and the published publications of the German Tax Authorities. In the meantime German Tax Courts published several decisions and the Act on the Introduction of Electronic Securities has come into force.
How does a blockchain work?
There is a wide range of applications for blockchain proponents, even outside of token speculation. Companies can use investment-token for the participation of their employees as shareholders and utility-token for financing upcoming projects or for tracking supply chains. Due to its transparency advantage over central systems, the technology is often mentioned in combination with the digitization of registers (e.g. German transparency register, German commercial register, German land register, etc.).
The underlying distributed ledger technology is a decentral-managed database that is stored in multiple locations, with identical copies stored at multiple users. A peer-to-peer network architecture enables data exchange between the users. A consensus mechanism is required for verification, before the database can be constantly synchronized and updated for all users. The transparent architecture guarantees the users access to status and history of all transactions. The subject of a transaction can be any information.
Especially in the blockchain, the data records are combined in blocks, which are linked to each other as a chain, whereby each newly attached block is calculated from the hash, a summary and verification of the previous block – comparable to a digital fingerprint. If the content of a block changes even minimally, the hash no longer matches the information stored in the following block. As a result, the entire chain becomes tamper-proof.
The coin/token in the blockchain describes the tamper-proof, digital and cryptographic registry, which might be most comparable to an analog document with inherent transferability. Miners receive tokens as a reward for “writing” new transactions into the next block. Regular users have a read-only access and no writing access. They pay transaction fees by token.
In summary, the main advantages of the technology are the transparency of the database and the protection against manipulation of the transaction history by individual users.
How is the taxation according to the law?
Current legal situation
Currently, the German Tax Law does not provide any explicit taxation of the income from the receipt, exchange, holding or sale of coins/token or the transactions. The subsumption of these virtual items is based on traditional Tax Law. Thus, as a rule, capital gains may be subject to taxation either as part of the trading income (Sec. 15 para. 1, para. 2 German Income Tax Code (“GITC”) or as part of the income from private sales transactions (Sec. 22 no. 2, Sec. 23 para. 1 sent. 1 no. 2 GITC). The exact classification depends on the (technical) circumstances of the individual case.
Act on the Introduction of Electronic Securities
The Act on the Introduction of Electronic Securities (“IESA”), which came into force on 4 June 2021, allows companies to use blockchain technology for corporate financing. As in the blockchain-strategy, the IESA emphasizes that the intended regulations should be technology-neutral. Key points of the IESA are the security registers – the central register of electronic securities and the cryptographic paper register – as well as the protection for investors. Accordingly, electronic securities would be treated as things under Sec. 90 German Civil Code.
While the central register of electronic securities would be subject to financial supervision, the cryptographic paper register must be kept on a decentralized, tamper-proof recording system in which data is logged chronologically and stored in a way that it is protected from unauthorized deletion and subsequent modification. It is required that the emitter publishes the entry of the cryptographic paper register and determines the owner of the register. Still, neither the publication nor the notification is constitutive for the creation of the cryptographic paper.
According to the Coalition Agreement, the German Federal Government intends to extend the possibility for issuing electronic securities (provided by the IESA) to shares as well.
The classification of the legal nature of the crypto-currencies made by the IESA does not provide any prejudicial effect for other regulations outside of the German Security law.
How is the taxation from the point of view of the German Tax Authorities?
VAT treatment of virtual currencies
In a letter dated 27 February 2018, the German Federal Ministry of Finance (“BMF”) complied with the decision of the European Court of Justice (“ECJ”) and outlined its understanding of the VAT treatment of virtual currencies. As the transactions are comparable to a conven-tional currency exchange, the exchange of a conventional FIAT currency into currency-tokens and vice versa are VAT exempt under Sec. 4 no. 8 lit. b VAT Act which must be interpreted in accordance with the VAT Directive. However, the VAT exemption is not applicable to virtual play money (so-called game currencies or in-game currencies, especially in online games), as these currencies do not constitute a means of payment within the meaning of the VAT Directive. The transfer of currency tokens for the mere payment of a fee is not subject to VAT, as the use of currency tokens is equivalent to the use of conventional means of payment, insofar as it does not serve any other purpose than that of a pure means of payment. With regard to the VAT treatment of mining, the services provided by the miners are not subject to VAT due to the lack of a concrete exchange of services.
Income tax treatment of virtual currencies
On 10 May 2022, the BMF published a long awaited BMF letter regarding individual questions on the income tax treatment of virtual currencies and other tokens. The letter does not cover recent developments such as the tax treatment of so-called Non-Fungible Tokens (“NFT”) explicitly. However, the principles of the BMF letter are to be applied to all open cases.
In the opinion of the BMF mining is an acquisition process which, depending on the individual case, can be qualified as trading income (gewerbliche Einkünfte) or income from (private) asset management (Vermögensverwaltung). In addition to the virtual tokens received for the block creation, the transaction fee and the fee received from an operator of a mining pool for providing computing power are also qualified as income. Regarding the distinction between business income and income from asset management, mining should likely be qualified as trading income if the taxpayer operates on a sustained basis for his own account and bears entrepreneurial risk as well as entrepreneurial initiative. The participation in general economic transactions is given by providing computing power to the network participants. However, it is irrelevant that the miner only receives a fee if a block is successfully created. Due to the high acquisition costs for the hardware and the high energy costs inevitably associated with the use of the hardware, mining should be qualified as trading income, although this presumption can be challenged if there is no intention to make a profit.
In individual cases, an activity could be qualified as mere asset management if the activity still represents the use of assets in the sense of collecting the benefits from intrinsic values to be preserved and the utilization of substantial assets through restructuring does not decisively become prominent.
The distinction principles should also apply to the tax treatment of a mining pool. Depending on the contractual arrangement, a mining pool could also be qualified as a co-entrepreneurship. In any case the operator of the mining pool only serves as a coordinator and does not bear the entrepreneurial risk alone. If the individual miners merely provide the operator with computing power in return for a payment, this should not be sufficient for a co-entrepreneurship.
If the requirements of a trading income are not met, the income from mining should be subject to so called other income (sonstige Einkünfte) according to Sec. 22 no. 3 GITC.
The BMF considers coins/token which are held as business assets to be non-depreciable assets as part of the fixed or current assets in accordance with the general principles of Balance Tax Law. Coins/token held as private assets are “other assets” within the meaning of Sec. 23 para. 1 sent. 1 no. 2 GITC. The market price for virtual currencies that can be determined and independently valued through stock exchanges, trading platforms and lists, represents a financial benefit for which the purchaser makes a payment. Profits from the sale of coins/token held as private assets are income from private sales transactions (private Veräußerungsgeschäfte) within the meaning of Sec. 22 no. 2, Sec. 23 para. 1 sent. 1 no. 2 GITC, if the period between acquisition and sale is less than one year. In contrast to the original draft, in its final letter the BMF retracts the application of Sec. 23 para. 1 sent. 4 GITC in the context of virtual currencies. This means that crypto-currencies, even in the context of lending or staking, can be sold tax-free after the expiry of a one-year holding period. For reasons of simplification, the acquisition and selling date resulting from the wallet should be decisive for determining the selling period. If the contractual transaction is to be decisive for the selling period, the taxpayer must prove the time of conclusion of the contract by means of suitable documents. If the sum of the profit realized from all private sales transactions is less than EUR 600 in a calendar year, the profit realized from the sale of the coins/tokens is tax-exempt according to Sec. 23 para 3 sent. 5 GITC.
The BMF letter clarifies that also an exchange transaction between different virtual currencies (just as the exchange transaction of units of a virtual currency into units of a state currency) leads to a sales transaction within the meaning of Sec. 23 para. 1 sent. 1 no. 2 GITC as well and that the profit resulting from such exchange transactions is also subject to tax upon sale under the requirements of Sec. 23 para. 1 sent. 1 no. 2 GITC. In addition, the selling period under Sec. 23 para. 1 sent. 1 no. 2 sent. 3 GITC starts to run again from the beginning after each exchange, as for simplification reasons it is to be assumed that the tokens acquired first were sold first.
Depending on their design, tokens may also be regarded as securities or other financial instruments. For this purpose, tokens must be regarded as securities within the meaning of Sec. 2 para. 1, para. 4 German Securities Trading Act. If the right conveyed by the token is a debt security and thereby creates a capital claim within the meaning of Sec. 20 para. 1 no. 7 GITC, the income received during the holding period is to be qualified as income from capital assets within the meaning of Sec. 2 para 1. sent. 1 no. 5, Sec. 20 GITC. Accordingly, a sale of the debt certificate falls within the scope of Sec. 20 para. 2 sent. 1 no. 7 GITC. Thus, capital gains from crypto-currencies can be taxed in certain cases at the capital gains tax rate of 25%, instead of the personal income tax rate.
What follows from the current case law?
Currently, there is (still) no case law on the taxation of profits from the sale of virtual currencies by the German Federal Court of Finance (“BFH”). With regard to the decision of the Cologne Tax Court the plaintiff has withdrawn the appeal originally filed against this decision before the BFH in the meantime.
Cologne Tax Court: profits from the sale of cryptocurrencies are subject to income tax
The facts on which the decision was based were as follows: The taxpayer acquired Bitcoins valued at approximately EUR 20,000 via a trading platform in the years 2014 to 2016. In the year of dispute 2017, he exchanged the Bitcoins through numerous transactions on various trading platforms first into Ethereum and Monero and then back into Bitcoin. He thereby generated a profit in the amount of EUR 3,441,261.70, which he declared as income from private sales transactions in his income tax return (Sec. 22 no. 2, Sec. 23 para. 1 sent. 1 no. 2 GITC). The taxpayer did not engage in mining. The tax office assessed the income tax for 2017 in accordance with the declaration – initially subject to a conditional review, which the Tax Office revoked at the beginning of 2019 by means of a subsequent assessment. After an unsuccessful appeal, the taxpayer claimed against the subsequent decision before the Cologne Tax Court. He argued that there was neither an (unchanged) asset nor had such an asset been sold, which is why there was also no private sales transaction. Even if the capital gains from exchange transactions with crypto assets are qualified as private sales transactions, the taxation is unconstitutional due to the structural enforcement deficit as well as due to a violation of the principle of certainty.
The Cologne Tax Court granted the claim only insofar as the profit in the amount of EUR 2,419.78 realized from an exchange of Bitcoins into Ethereum could not be determined within the sales period of Sec. 23 para. 1 sent. 1 no. 2 GITC. In all other matters the Cologne Tax Court rejected the claim as unfounded.
Crypto-assets are so-called “other business assets”
The Cologne Tax Court confirmed the view of the tax authorities and assessed the sales profits from the exchange transactions as taxable income from private sales transactions. The crypto-assets Bitcoin, Ethereum and Monero traded by the taxpayer are qualified as assets within the meaning of Sec. 23 para. 1 sent. 1 no. 2 GITC. According to the established case law of the BFH, the term “asset” in income tax law is to be interpreted broadly and on the basis of an economic approach. At the respective reporting date, there must be an economically beneficial asset that can be considered a realizable asset. In the opinion of the Cologne Tax Court crypto-assets provide concrete opportunities and advantages in legal transactions. A certain value can and is attributed to them due to the demand on trading platforms. Whoever acquires crypto-assets receives clearly defined opportunities for profit in return for the services rendered, even if their realizability is subject to risk due to a possible price decline. In the same way, due to price increases, there is the possibility to resell the crypto-assets at a profit. If payments are made for the acquisition of the opportunity to profit, the opportunity to profit appears as a business asset. Contrary to the taxpayer’s view, crypto-transactions are not to be compared to pure gambling. In the case of gambling the opportunity to win is lost at the end of the game in accordance with the rules of the game. For crypto-transactions, on the other side, there are established markets, which enable the achievement of economic benefits through commercial trading. Unlike stakes in gambling crypto-assets do not expire due to expiry of time or due to speculation. For business assets, crypto-assets also have sufficient transferability, irrespective of civil law transfer options. According to the case law of the BFH, it is necessary and sufficient that legal transactions have found ways of transferring crypto-assets to a third party in return for payment via trading platforms and thereby realizing them economically.
Crypto-assets are economically attributable to the taxpayer
Contrary to the taxpayer’s view, the classification of crypto-assets as business assets does not depend on the determination of who is the owner of the crypto-assets under civil law. Instead, the attribution of (legal or economic) ownership under Sec. 39 German Fiscal Code is a legal consequence of the being a business asset, not a requirement for it. The Cologne Tax Court has not decided who is the legal owner of crypto-assets. In any case, economic ownership is attributable to the taxpayer pursuant to Sec. 39 para. 2 German Fiscal Code.
No structural enforcement deficit and no violation of the principle of certainty
The taxation of crypto-currency pursuant to Sec. 23 para. 1 sent. 1 no. 2 GITC does not constitute an enforcement deficit that leads to taxation that is contrary to equality or otherwise in violation of the law. The fact of anonymous sale between the contracting parties is not sufficient enough for this purpose. Tax deficits in the trading of crypto-assets are based on factual difficulties of tax control. Deficits in enforcement are not sufficient in themselves to establish the unconstitutionality of a legal provision. Furthermore, there are certain control options and identifications can be made, among other things, by means of collective information requests from the tax investigation department to trading platforms, so that there is no total anonymity. It is also conceivable to retrospectively read the blockchain and to identify the persons behind the transactions. The assessment period of ten years in the case of tax evasion bears the risk for the taxpayer of still being identified within a very long period of time (Sec. 169 para. 2 sent. 2 German Fiscal Code).
Berlin-Brandenburg Tax Court: private sales transactions
The Berlin-Brandenburg Tax Court had to decide whether there were serious doubts to the legality of the German income tax assessment for a suspension of enforcement (Sec. 69 para. 3, para. 2 German Tax Court Regulations). The tax authority had qualified the income from the purchase (or exchange) of Ethereum with Bitcoin as income from private sales transactions (Sec. 22 no. 2, Sec. 23 para. 1 sent. 1 no. 2 GITC).
The taxpayer countered that the income had not been generated by acquisition and sale by explaining the technical processes and referring to the above-mentioned whitepaper. He was not entitled to any enforceable rights of economic value, so that it was not a matter of “other business assets” within the meaning of the regulation. The Berlin Court of Appeal has determined – in a criminal proceeding – that Bitcoin is not an accounting unit. The taxation is un-constitutional because of a structural enforcement deficit and leads to discrimination against German citizens.
The tax authority pointed out that the German Federal Financial Supervisory Authority had qualified Bitcoins as an accounting unit and financial instrument within the meaning of Sec. 1 para. 11 German Banking Act, so that the principles of foreign currency transactions were applicable.
The Berlin-Brandenburg Tax Court rejected the taxpayer’s application because it had no serious doubts about the taxation. Considering the literature opinion, it classified Bitcoin as tax-entangled, private assets that would be accepted as payments in business use. A detailed examination of the technical processes would be reserved for the principle proceeding – if it needs to be recognized at all with regard to the common definition of assets.
In the reasons, the Berlin-Brandenburg Tax Court refers to the crypto-currency Bitcoin, where-by the case concerned Ethereum. It seems questionable whether the Berlin-Brandenburg Tax Court was not aware of the difference of these two crypto-currencies or if it was irrelevant for taxation according to its legal opinion.
Nuremberg Tax Court: Doubts about the opinion of the German Tax Authorities
At first the taxpayer had explained profits from the purchase and sales of various different crypto-currencies which were not Bitcoins essentially. Later, he explained trades in connection with a hacker attack, which caused a loss.
In his opinion, there was no special legal basis to authorize the taxation and referred to the proceedings at the Baden-Wuerttemberg Tax Court, which had been admitted for revision – and completed in the meantime – and which had casually doubted the tax liability. There was a structural enforcement deficit, as the Tax Authority depends on the voluntary information provided by taxpayers. Also, the extreme volatility of crypto-currencies would preclude a classification of the latter as “other business assets”.
The Nuremberg Tax Court objected that the tax authority did not understand the technical processes and the determination of the acquisition costs. Thus, they did not determine the relevant facts according to Sec. 88 German Fiscal Code. The Tax Authority is responsible to determine the taxable situation, which increases the tax load of the taxpayer. This applies in particular to factually and legally complex assessments.
The Nuremberg Tax Court explained that the existing tax regulations are sufficient in order to assess the taxation of business transactions with a crypto-currency. The Nuremberg Tax Court was unable to follow the remarks of the Berlin-Brandenburg Tax Court, although it clearly states that the Berlin-Brandenburg Tax Court did not deal with the differences between Bitcoin and Ethereum in a sufficient depth.
What can be expected in the near future?
It remains to be seen whether the blockchain-strategy will lead to a legislative adjustment of Sec. 23 para. 1 sent. 1 no. 2 GITC. The Blockchain Bundesverband e.V. has already made suggestions, which derive the tax valuation differences based on the claim connected with a coin/token in the sense Sec. 194 para. 1 German Civil Code.
Further, the commencement/entry into force of a European Regulation on markets in crypto-assets (“MiCA”) is in prospect. A preliminary agreement on a draft from the European Commission was reached by the Council and the European Parliament in the end of June 2022.
The MiCA-regulation deals with currency-token and utility-token and therefore stands in tension with the German eWpG. During the votes on the final draft of the MiCA-regulation, the European Parliament voted against a ban on the energy-intensive consensus and protection method (“Proof of Work method”), which would have prohibited member states from mining crypto-currencies such as Bitcoin and Minero. Due to the high energy consumption of crypto-currencies, the committee rapporteur Stefan Berger (CDU) had proposed to include crypto-assets in the scope of the Taxonomy Regulation just like all other financial products.
In addition, the OECD has published a draft of a legal framework for the international exchange of tax-relevant data on crypto assets (“Crypto-Asset Reporting Framework”).
With a view to other countries, the next developments on crypto-currencies remain exciting. For example, El Salvador, Venezuela and the Central African Republic have recognized bitcoin as a means of state payment, while Egypt, Iraq, Qatar, Oman, Morocco, Algeria, Tunisia, Bangladesh, China, Turkey and Russia have imposed an absolute crypto ban.
In Austria, sales profits from crypto-currencies of individual persons will be taxed as capital income in the future. The law came into force on 1 March 2022 and applies with retroactive effect to acquisition transactions made after 28 February 2021. It remains to be seen whether all profits from crypto-currencies will also be taxed as capital income in Germany in the future.
Can we support you?
The challenges of a blockchain structure as a vehicle for corporate and real-estate financing or participation are technically demanding and complex in terms of Financial, Data Protection and Tax Law.
If you already declared income from trade with crypto-currencies in your income tax declaration, it is recommended to keep the validity of the income tax assessments open by redresses.
