Austrian Bitcoin Lending: Continued income is taxable
Anyone who lends Bitcoin through a cryptocurrency exchange, lending platform or DeFi protocol will usually receive a corresponding return on a regular basis. Depending on the product, providers call it interest, reward, income, or earned income. For Austrian tax purposes, the product name itself is not important.
When Bitcoin is provided to other market participants for a fee, the money received is usually regarded as continuing income from the cryptocurrency. Once investors are able to dispose of these rewards, taxes are usually required. Converting received bitcoins into euros is not a requirement.
This brings specific risks to investors. Taxes are calculated based on the euro value at the time of receipt of the award. If the price of bitcoin falls thereafter, the tax payable may exceed the value of subsequent holdings of these currencies.
What is Bitcoin Loan?
In Bitcoin lending, investors hand over the currency to a platform, company, borrower, or decentralized agreement within a limited time. In return, investors receive a payment.
Depending on the product, the bitcoins provided may be used to:
fund loans to other users,
provide liquidity for trading positions,
provide bitcoins to institutional market participants,
fund a centrally managed credit pool, and
provide liquidity within the DeFi protocol.
Payments can be made in the form of Bitcoin, stablecoins, other tokens, or legal tender. Typically credited to the platform account on a daily, weekly or monthly basis.
Austria's Income Tax Law clearly treats payments received for the provision of cryptocurrencies as continuing income from cryptocurrencies. The Ministry of Finance includes both interest earned on cryptocurrency lending and remuneration earned for providing cryptoassets to liquidity and credit pools.
Bitcoin loans are usually taxed when they are actually received
The key tax point is not the loan reward sold later, but when the reward is received. All persistent cryptocurrency revenue must be valued when it reaches investors.
Generally speaking, the asset is deemed to have been received once the recipient is legally and financially able to dispose of it. On lending platforms, this may be the moment when a payment is credited to a user's account and investors can withdraw, redeem, transfer or lend the money again.
There is no need to make payments to a bank account. Amounts credited in the form of Bitcoin or other crypto assets can itself constitute taxable income.
Typical receipt points include:
daily crediting to an accessible platform account,
monthly payment to a wallet,
allocation of freely transferable reward tokens,
automatic crediting of instant reinvestment, and
payment at the end of a fixed borrowing period.
For payments that are only shown in digital form but are not yet available, whether they have been counted as received depends on the terms of the contract. If investors are unable to dispose of these currencies or claim payment, the point of receipt in the tax sense may be delayed.
Conversion into euros is not required for first tax payment
A common misconception is that cryptocurrency gains are subject to tax only if funds enter bank accounts. But this does not apply to borrowing.
Continuing income is taxed at its value when received. Generally, the situation is the same whether investors:
immediately convert the bitcoin they receive into euros,
leave it on the platform,
transfer it to a hardware wallet,
automatically lend it again,
or convert it to another cryptocurrency,
.
The Austrian Ministry of Finance has clearly stated that for continuing cryptocurrency income, the value of cryptocurrency or other payments received at the time of receipt constitutes a taxable basis.
How to calculate taxable Bitcoin loan income
When loan interest is paid in Bitcoin, the amount received needs to be denominated in euros when received. Usually reference is made to available prices from cryptocurrency exchanges. If there is no exchange price, you can use the quotes provided by a cryptocurrency trader.
This euro value serves two purposes:
It constitutes continuing income subject to immediate tax.
It becomes the tax acquisition cost in the currency received.
Austria's Cryptocurrency Regulations clearly define this valuation method. Valuations made as part of the capital gains tax deduction are usually also binding on the assessment.

Example: Loan income paid in Bitcoin
An investor lent Bitcoin through the platform. In June, he was paid 0.0005 BTC. At the time of crediting, the Bitcoin price was 60,000 euros.
The calculation is as follows:
Payment received: 0.0005 BTC
Bitcoin price when received: 60,000 euros
Taxable income: 30 euros
Tax at a rate of 27.5%: 8.25 euros
This 30 euros is also included in the purchase cost of receiving 0.0005 BTC.
Therefore, even if the euro is not received and the currency is not sold, investors will still have to pay a tax of 8.25 euros.
A second calculation may arise on subsequent sales
The tax received only deals with continuing borrowing income. If the value of the bitcoins received later changes, further gains or losses will be incurred on subsequent sales.
Continuing the example above:
Value of Bitcoin when received: 30 euros
Subsequent disposal: 45 euros
Taxable disposal gains: 15 euros
Additional tax at 27.5% rate: 4.13 euros
These 30 euros will not be taxed again. They constitute the cost of acquisition. Only the subsequent gain of € 15 is usually taxed at the time of sale.
If the value falls from 30 euros to 20 euros, subsequent disposals typically result in a loss of 10 euros. The loss can be offset against certain other investment income within the scope of statutory loss offset rules.

Falling prices may cause liquidity problems
When the price of bitcoin drops sharply after being credited, taxing the value immediately when received can become tricky.
Example:
Loan incentive upon receipt: 10,000 euros
Tax at 27.5% tax rate: 2,750 euros
Value of incentive upon tax: only 5,000 euros
The initial tax amount will not be automatically reduced due to future declines in Bitcoin prices. Loss of value is usually recognized only if it is realized on a tax basis.
If investors later sold the coins for € 5,000, there would be a loss of € 5,000 compared to the acquisition cost of € 10,000. Whether the loss can be fully utilized depends on whether there is appropriate positive investment income available for offset during the same period.
Therefore, investors should not assume that all borrowing income can be reinvested. Some of the value may be needed to pay the ensuing taxes.
A special tax rate of 27.5% is usually applied to loans
In Austria, a special tax rate of 27.5% is applied to continuing income from cryptocurrencies. As a result, cryptocurrency income typically does not push up the progressive tax rates that apply to investors 'other income.
This usually applies to publicly offered lending products from exchanges and crypto service providers, provided that the activity falls within the category of private assets and does not go beyond simple asset management.
The 27.5% tax rate generally covers:
ongoing loan payments,
and subsequent appreciation in the value of the currency received.
Private cryptocurrency loans may be an exception. If the underlying agreement is not, in law and in fact, a public offering, the income may fall under progressive income tax rates. Depending on total income, the tax rate may be lower or much higher than 27.5%.
"Pledge" tags cannot circumvent loan taxes
Many platforms promote interest-bearing encryption products as "pledge" even if currency is not technically used to verify the blockchain. In fact, these assets are usually provided to platforms or other market participants.
Real, classic pledges are handled differently in Austria. If a new cryptocurrency is obtained through participation in transaction processing or block verification, it will usually not be taxed when received. Instead, the currency received is recorded at zero acquisition cost, so all sales revenue may be subject to tax on subsequent disposal.
This exception only applies to actual pledges. The Ministry of Finance has clearly warned that products described only as "pledged" may constitute loans for tax purposes. If the arrangement provides cryptocurrency economically for a fee, the payment will be subject to tax when received.
Therefore, what matters is the substance rather than the product name, especially:
Who can dispose of Bitcoin during its lifetime?
Is the currency used for blockchain verification?
Has the platform obtained economic use rights of assets?
Is there a right to claim the return of the same type and amount of Bitcoin?
Are fixed or variable returns committed?
Do investors bear credit or counterparty risk?
Products labeled "Bitcoin Pledge" require careful scrutiny in particular, because Bitcoin itself does not use the classic proof-of-stake mechanism.
DeFi and liquidity pool income may also be considered loans
Austrian regulations are not limited to centrally managed cryptocurrency exchanges. Payments from decentralized credit and liquidity pools can also be ongoing cryptocurrency revenue.
The Ministry of Finance listed remuneration for providing cryptocurrency to liquidity or credit pools as one of the possible scenarios. The term "liquidity mining" is often used here.
However, tax treatment for decentralized products may be more complex. Depending on the agreement, users may receive:
ongoing reward tokens,
interest-bearing claims for the agreement,
liquidity pool tokens,
tokens with increasing value, and
multiple different payments simultaneously.
Not every increase in the value of such tokens automatically constitutes continuing revenue. In some cases, revenue will only be generated when the claim is redeemed, redeemed or disposed of. Therefore, the technical and legal structure of each protocol needs to be analyzed separately.
Depositing Bitcoin is different from earning interest
Transferring Bitcoin into lending products needs to be distinguished from the tax issues of continuing rewards.
Under ordinary supply arrangements, investors receive the right to claim the return of Bitcoin or the corresponding amount. Austrian law includes claims for reimbursement arising from the provision of cryptocurrency into the definition of cryptocurrency.
Therefore, simply establishing such a reimbursement claim will not automatically trigger a tax on all Bitcoin gains accumulated as of that point. Continuing income is usually generated through additional payments received.
The specific assessment depends on the contract. If users end up exchanging Bitcoin for different types of tokens, securities, funds, or other assets, a taxable exchange transaction may arise rather than just a simple loan.
Automatic reinvestment does not necessarily prevent recognition of "receipt"
Many platforms will credit rewards and immediately lend them again. Users will then see a daily or weekly increase in interest-bearing balance.
Automatic reinvestment does not necessarily mean that no taxes are generated. If an investor initially has legal and economic control over the payment and then the payment is reinvested, there may be two tax events:
receiving taxable borrowing income, and
making a new supply in the currency received.
Whether control actually exists depends on the terms of the contract. Factors to consider include whether users can turn off automatic reinvestments, withdraw rewards, or otherwise dispose of them. Tax "receipt" usually requires both legal and de facto control.
What is the status of the fixed lock-up period?
Periodic products usually lock Bitcoin for a specific period of time. The platform may continue to display payments, but actual payments will only be made at the end of the period.
Simply showing expected income does not necessarily constitute a tax "receipt". If the user can neither transfer nor withdraw the displayed currency and does not have an enforceable immediate disposal request, then "receipt" usually only occurs when the lock is unlocked or expires.
The situation may be different if the platform irrevocably credits rewards and simply delays payment for technical reasons. The answer to this question cannot be based solely on the words "locked" or "fixed".
Investors should retain the terms and conditions and account statements. These documents should show: when
claims are generated,
awards are finalized, when
will be available, whether
may expire prematurely, and whether
may be paid during the duration.
Old positions may become more complex through borrowing
Bitcoin acquired as of February 28, 2021 (inclusive) are generally considered old assets. They were originally outside the scope of Austria's newer cryptocurrency tax regime.
If such old positions are used to generate persistent cryptocurrency income after February 28, 2022, the newer system has been applied to the resulting rewards. Borrowing payments received are treated as new assets.
This means:
Original old Bitcoin positions still need to be reviewed separately.
The resulting borrowing incentives are usually taxed when received.
Reward currencies are considered newly acquired cryptocurrencies for tax purposes.
Their subsequent sales usually follow the rules of new assets.
The use of older bitcoins in lending products should be carefully documented. Depending on how the contract was drafted, it may also be necessary to review whether the supply affected the tax classification prior to the original position.
Austrian provider or foreign provider?
If a domestic party has a withholding obligation, capital gains tax can be deducted by the provider and paid directly to the tax bureau. For investment income generated after December 31, 2023, certain Austrian debtors and crypto service providers usually have withholding obligations. Once correctly deducted, income tax is usually settled.
Starting from the 2025 calendar year, Austrian withholding agents must also provide standardized tax reports on encryption income upon request. It can list the continuing revenue generated by the provision of cryptocurrencies.
Foreign platforms generally do not subject any Austrian withholding taxes. Investors with tax liability in Austria usually need to determine their income and declare it on their income tax return.
The location of the platform does not exempt Austria from tax obligations. The most important factors are where the investor lives for tax purposes and which country has tax rights under any applicable double taxation treaty.
Foreign withholding taxes may play a role
In cross-border borrowing, countries other than Austria may also impose tax requirements. For the purposes of double taxation agreements, the Treasury Department typically classifies payments made for the paid provision of cryptocurrencies as interest.
Under the OECD Model Convention, the recipient's country of residence usually has the right to tax. Source countries can have additional limited taxation rights. The actual withholding rate applicable and whether foreign taxes can be credited in Austria depend on the specific double taxation agreement.
Therefore, for foreign platforms, investors should also check:
whether withholding tax has been deducted,
whether there is a tax certificate,
whether the relevant double taxation treaties allow credit, and
whether there is a need to apply for a tax refund abroad.
What happens if a lending platform goes bankrupt?
Bitcoin lending brings both economic and tax risks. Depending on the structure, investors transfer currencies to the platform and only hold the right to claim repayment.
If borrowing income has been recognized on tax and the platform later loses its currency or goes bankrupt, the original tax amount will not disappear retroactively. Whether subsequent breaches of claims can be recognized as tax losses depends on the specific legal structure of the claim and the loss set-off rules.
The following situations are particularly difficult:
Rewards are taxed at high prices,
currencies cannot be withdrawn,
The Bitcoin price then fell, and
the platform later lost its ability to pay.
In this case, it should not be assumed that tax losses can be recognized without individual review.
Business activities or private asset management?
The application of special tax rates generally requires that lending activities fall within the scope of private asset management.
If the nature and scale of the activity exceeds this range, operating or business income may be generated. The Ministry of Finance has listed commercial cryptocurrency trading and commercial mining as cases where progressive income tax rates may apply. Specific distinctions are always based on specific facts.
Large investments by themselves do not turn private borrowing into business activities. Relevant factors may include organization, continuity of activities, size, use of external capital and degree of participation in general business transactions.
What data should investors record for Bitcoin lending
For each lending platform or agreement, at least the following information should be stored:
The type and amount of bitcoins provided,
Deposit and repayment dates,
the contractual terms of the lending product,
Term and cancellation options,
the date of each reward is credited,
the amount paid in Bitcoin or other token,
the euro price at each receipt,
The source of the price used,
the capital gains tax that has been withheld,
the acquisition cost of the award currency received,
subsequent sales or conversions,
platform fees,
wallet address and transaction ID,
tax report and account statement,
applicable foreign tax certificate.
Daily rewards may generate a large number of separate taxable income records. The right cryptographic tax software can simplify analysis. However, the results should still be checked against actual platform data and product legal structure.
Conclusion: Bitcoin loan interest is subject to tax when received
In Austria, bitcoin borrowing can generate ongoing taxable income even before a satoshi is exchanged for euros. What usually matters is the moment when investors gain legal and economic control of payments.
The euro value of Bitcoin received is subsequently:
is recorded as ongoing cryptocurrency income,
is usually taxed at a rate of 27.5%,
and is also stored as the acquisition cost of the reward currency.
If the price increases further thereafter, additional taxable gains may be generated on subsequent sales. If prices fall, tax losses usually only become apparent when they are realized later.
Special attention should be paid to the following situations:
Incentive for automatic reinvestment,
Fixed lock-up period,
Foreign lending platform,
Credit products sold under the banner of "pledge",
DeFi and liquidity pool model,
Old Bitcoin positions,
Private cryptocurrency loans offered privately,
Missing historical price and transaction data.
Therefore, investors should not only record their deposits and withdrawals. For tax calculations, each available award credit and its current euro value are crucial.
