Anyone mining crypto-assets in Germany earns taxable income, and does so from the very first reward. The only open question is which category of income your mining falls into: income from a trade or business under section 15 of the Income Tax Act (EStG), or other income from services under section 22 no. 3 EStG. Everything else follows from that classification, from the tax rate to trade tax to the question of whether you have to register a business. This guide walks you along the line drawn by the Federal Ministry of Finance and shows you at each point what you can check yourself.
The governing text is the Ministry’s circular of March 6, 2025 on individual questions of the income tax treatment of crypto-assets. It recast the earlier circular of May 10, 2022 and deals with block creation in margin numbers 35 to 47. Every statement in this text on the taxation of cryptocurrencies comes from that source or directly from the law.
Crypto mining is never private asset management for tax purposes
This is the sentence on which most misunderstandings hang. Many investors simply transfer what they have learned about buying Bitcoin to mining: hold for a year, then sell tax-free. On the income side, that logic does not apply to mining.
Margin number 39 of the circular states expressly that block creation does not constitute private asset management. The reasoning is coherent: block creators receive the block reward and the transaction fees in exchange for computing power they have supplied. The activity therefore matches the picture of a service provider. Anyone who renders a service and is paid for it is not managing assets but generating income.
Private asset management describes, in tax law, the mere holding and reallocation of one’s own assets without offering a service of one’s own on the market. That is precisely what is missing in mining. The consequence: every inflow from block creation is taxable income in the year it accrues, regardless of whether you subsequently sell the coins or leave them untouched.
Commercial mining or other income: three criteria decide the classification
Whether your mining activity is a commercial activity is governed by the requirements of section 15 (2) EStG. The Ministry works through them individually for block creation in margin numbers 36 to 38.
Sustained activity (margin number 36): block creation is sustained if it is designed to be repeated. A one-off attempt over a weekend is not, a permanently running machine is.
Intention to make a profit (margin number 37): the activity must be capable, over time, of producing an overall profit. Anyone who pays more for electricity over the years than the rewards are worth does not meet this criterion.
Participation in general economic activity (margin number 38): in mining this criterion is almost always met. Simply by making your computing power available to the network for verifying transactions, you are participating in economic activity. The fact that your payment depends on successfully creating the block does not, according to the Ministry, stand in the way of this.
In practice, then, it is mainly scale that decides. If all three criteria are met, you have income from a trade or business. If one is missing, section 22 no. 3 EStG applies. Margin number 45 names exactly this case as an example: where the activity is not sustained, mining income is taxable as a service under section 22 no. 3 EStG.
There is no hard numerical threshold for how many graphics cards make mining commercial. The circular names none, and neither does the law. Anyone who quotes you such a threshold is repeating a rule of thumb, not the legal position.
Do I have to register a business for crypto mining?
Yes, as soon as your activity meets the criteria of section 15 (2) EStG. The obligation itself follows from trade law, namely section 14 (1) of the Trade Regulation Act (GewO): anyone starting the independent operation of a standing trade must notify the competent authority. The competent body is your municipality’s trade office. Depending on the municipality, registering a business usually costs a two-digit euro amount.
The order matters: registering a business is the consequence of your tax classification, not its cause. You do not become commercial by registering a business, and you do not escape commercial classification by failing to register one. The tax office examines the actual circumstances. Conversely, anyone who mines only occasionally and falls under section 22 no. 3 EStG needs no business registration.
After registration, the tax office will usually send you the questionnaire for tax registration. In it you state, among other things, what profits you expect and whether you want to use the small business scheme.
The 256-euro exemption limit on other income and its catch
If your mining falls under section 22 no. 3 EStG, an exemption limit applies. Margin number 45 puts it this way: the income is not subject to income tax if, together with other income from services, it amounted to less than 256 euros in the calendar year (section 22 no. 3 sentence 2 EStG).
Two details are regularly reported incorrectly. First, this is an exemption limit, not an allowance: at 255 euros everything remains tax-free, at 256 euros the full amount is taxable. An allowance, by contrast, would only capture the excess portion. Second, the limit refers to income, meaning the amount after deduction of income-related expenses, and it applies to all service income of a year taken together. Anyone who provides another service under section 22 no. 3 EStG alongside mining has to add the two together.
Worked example, rounded and for illustration only: your pool payouts over the year add up to inflow values of 470 euros. You document electricity costs and depreciation of 200 euros in total. Your income is 270 euros, which is above the exemption limit, and the full 270 euros is subject to your personal income tax rate. Had the documented costs been 215 euros, income would be 255 euros and no income tax would arise. At this point clean bookkeeping is worth more than any optimization.
Electricity costs, hardware and depreciation: what you can deduct when mining
Margin number 47 of the circular is the most important line in the whole document for private miners. It names expressly, as income-related expenses, the costs of acquiring the necessary hardware and software, where applicable in the form of depreciation, as well as the costs of electricity consumption.
Depreciation means that you spread the acquisition costs of a device over its normal useful life instead of deducting them in full in the year of purchase. For computer hardware the tax authorities have allowed a useful life of one year since 2021, which in effect amounts to an immediate deduction.
For electricity you need a comprehensible separation. A dedicated submeter at the socket is the cleanest route, because it separates the mining hardware’s consumption from household electricity. Without such a measurement you are estimating, and an estimate is something you have to be able to justify to the tax office. With commercial mining the same items are called business expenses; the system is the same.
One limit applies in both cases: shares attributable to private use of the computer are not deductible. Anyone who plays games in the evening on the same graphics card cannot claim the full electricity costs.
Commercial mining: trade tax, the 24,500-euro allowance and accounting duties
If your activity is classified as a trade or business, further taxes and duties come on top of income tax. The most important item is trade tax.
It is calculated under section 11 of the Trade Tax Act (GewStG): the trade income is rounded down to the nearest 100 euros and, for natural persons and partnerships, reduced by an allowance of 24,500 euros. The tax base rate of 3.5 percent is applied to the remainder, and the municipality multiplies the resulting base amount by its multiplier.
Worked example, rounded: with trade income of 30,000 euros, 5,500 euros remain after the allowance. That produces a base amount of 192.50 euros. At a multiplier of 400 percent you pay 770 euros in trade tax. The decisive part is the second step: under section 35 (1) EStG your income tax is reduced by four times the base amount, here likewise by up to 770 euros. At a multiplier of around 400 percent, trade tax is therefore largely neutralized for natural persons. If your municipality’s multiplier is significantly higher, a genuine additional burden remains. The credit is also limited to the trade tax actually paid and to the maximum reduction amount.
On accounting: an obligation to keep books under section 141 of the Fiscal Code (AO) only arises once the tax office notifies you of it and your business has reached total turnover of more than 800,000 euros in the calendar year or a profit of more than 80,000 euros in the financial year. Below that, the cash-basis income statement under section 4 (3) EStG is sufficient. For that case margin number 44 holds a peculiarity that is easily overlooked: the mined crypto-assets produce business income at the time of receipt, but you may only deduct their acquisition costs as business expenses at the time the sale proceeds accrue or the assets are withdrawn. The coins belong in the continuously maintained register under section 4 (3) sentence 5 EStG.
One difference from private assets is particularly expensive: within business assets there is no one-year holding period. Every later sale of the mined coins is a taxable event, no matter how long they sat in the business.
Time of receipt: how to determine the value of a mining reward
It is not the sale that is taxable but the receipt. Margin number 47 provides that crypto-assets obtained through block creation are to be recognized under section 8 (2) sentence 1 EStG at the market price at the time of acquisition. That value is your income, and it remains so even if the price falls afterwards.
As a market price you may, under margin number 43, use the price from a trading platform or a web-based price list; the Ministry expressly names Coinmarketcap and CoinGecko there as examples. Margin number 91 additionally contains a non-objection rule under which a daily price may be used instead of the price at the exact moment. For pool payouts arriving minute by minute, that is a considerable relief.
An example using a price measured on this day: on September 19, 2026 at 12:38 UTC, Bitcoin was quoted by CoinGecko at 70,785 euros. A pool payout of 0.0005 BTC would be recognized on that day as income of around 35 euros. If you sell those 0.0005 BTC three months later at a lower price, that changes nothing about the 35 euros; it merely produces an additional loss from a private disposal transaction. It is precisely this separation of receipt and sale that puts miners under pressure in years of falling prices, because the tax on the high inflow value falls due even when the coins are worth less by then. Anyone who plans for this early sets aside part of every reward for the payment.
Holding period after receipt: why mined coins count as acquired
For the time after receipt, the familiar system returns, and this is where the good news lies. Margin number 42 makes clear that crypto-assets allocated for block creation are acquired, because an exchange-like transaction is involved. Margin number 54 expressly counts them among assets acquired for consideration.
The same rule therefore applies to mined coins held as private assets as to purchased ones: a sale within one year of receipt is a private disposal transaction under section 23 (1) sentence 1 no. 2 EStG, a sale after that is not taxable. The one-year period begins with the receipt of each individual reward, so separately for every payout. Under section 23 (3) sentence 5 EStG, gains also remain tax-free if the total of all private disposal transactions in the calendar year is below 1,000 euros; up to the 2023 assessment period the figure was 600 euros. How these periods interact with savings plans and FIFO is set out in our overview of Bitcoin and taxes in Germany.
This two-part structure is the core of the tax treatment of mining: taxation on receipt under section 22 no. 3 or section 15 EStG, and thereafter the normal rules for private disposal transactions. Anyone explaining only one of the two levels is explaining half of it.
How does the tax office check crypto gains? The records you must keep
The duties to cooperate and to retain records for private assets are set out in margin numbers 100 to 103. The text there is clearer than many expect.
The tax authority may, observing the general rules on the burden of proof, require you to provide evidence, for instance through questionnaires. Tax reports that appear plausible can aid comprehensibility, but the authority may request the underlying documents and files, such as transaction overviews or CSV files. After exhausting its own investigations, which expressly include the use of a block explorer, the Ministry even considers it proportionate to request screenshots from a wallet or an exchange account.
Margin number 103 lists what your presentation may cover. For mining these are above all: the time of acquisition, the quantity received and the type of transaction, with mining and forging named separately there, the platform used, the market price applied together with its source, and, on a later sale, the time of disposal, the quantity, the proceeds and the disposal costs. Under margin number 102, every private disposal transaction must be capable of being traced individually and on its own.
In practice this means: export your pool’s payout history yourself at regular intervals rather than relying on the provider’s interface, and record the price source for each day. A tax tool or portfolio tracker takes most of this work off your hands by valuing inflows at daily prices and tracking the holding period for each inflow. Responsibility for accuracy nevertheless remains with you.
Pool mining, solo mining and cloud mining compared for tax
The chosen form of mining changes nothing about the category of income, but it does change the details.
Solo mining means mining on your own account without joining others. For tax purposes it is the simplest case: you rarely receive anything, and when you do, it is the full block reward, to be valued at the time of receipt.
Pool mining bundles the computing power of many participants. Margin number 40 records that, at the level of the mining pool, a co-entrepreneurship may exist depending on the contractual arrangement in the individual case. It does not exist, in any event, where the miners merely make computing power available to the operators for payment within a service relationship. With the common pools that is the standard case. Margin number 46 adds that no distinction is to be drawn for tax purposes between the block reward and the transaction fees.
Cloud mining means that you rent computing power instead of operating your own hardware. Margin number 46 expressly includes participation in a cloud mining service within the same treatment. For tax purposes the case is therefore no more favorable. Economically it is riskier, because you do not control the facility and providers in this segment have repeatedly failed in the past.
If you later sell your rewards, that runs through a trading platform. Which venues are authorized in Germany and how they differ on fees and tax reports is shown in our comparison of crypto exchanges.
Is there VAT on crypto mining?
No. The Ministry’s circular of February 27, 2018 on the VAT treatment of Bitcoin and other so-called virtual currencies classifies miners’ services as non-taxable transactions. The reasoning: there is no exchange of services with an identifiable recipient. The transaction fee is paid voluntarily and bears no direct connection to the miners’ service, and the remuneration in the form of new Bitcoin by the system itself is likewise not consideration in the VAT sense.
This statement concerns VAT alone. It changes nothing about liability to income tax and, where applicable, trade tax. If as an entrepreneur you sell other services, such as hosting for third-party miners, that is a separate question and generally subject to VAT.
Liquidity mining and staking are not mining
Three terms are regularly confused, and the confusion leads to incorrect tax returns.
Mining in the sense of this text is block creation by proof of work. Forging is its counterpart under proof of stake, that is, active block creation as a validator; the Ministry deals with it in the same margin numbers as mining. Passive staking, by contrast, meaning the provision of a stake through a pool or a platform without creating blocks yourself, is under margin number 48 subject to taxation under section 22 no. 3 EStG as the reaping of fruits falling within private asset management. The classification looks similar, the route there is a different one, and a commercial classification regularly does not come into consideration here. The details are set out in our guide to staking and taxes in Germany.
Liquidity mining, finally, has nothing to do with block creation. It means providing capital in a decentralized trading pool in return for a fee. The term carries the word mining, but the tax treatment follows the rules for lending and liquidity pools, not those for block creation.
Crypto mining tax: what to take away
- Classify your activity honestly. Check sustained activity, intention to make a profit and scale against margin numbers 36 to 38 of the circular. If the check produces a commercial activity, register the business rather than waiting to be asked. Our guide to crypto tax in Germany gives an overview of the whole framework.
- Record every inflow on the day it accrues. Quantity, date, daily price and price source belong in a file you keep yourself. If you do not want to do that by hand, a crypto tax tool takes over the valuation and the holding periods for each reward.
- Set money aside for the tax before you sell. The tax on the inflow value falls due even if the price drops later. A fixed share of every reward, set aside when you sell through a regulated trading platform, prevents the nasty surprise in the tax assessment.
