Bitcoin Lending in Austria: When Tax Falls Due

Bitcoin lending in Austria: when the ongoing income is already taxed

Anyone who lends Bitcoin through a crypto exchange, a lending platform or a DeFi protocol usually receives a recurring payment in return. Depending on the product, providers call this interest, rewards, yield or earn income. For Austrian tax purposes, the name of the offer carries no weight.

Where Bitcoin is made available to another market participant for consideration, the payments received generally count as ongoing income from cryptocurrencies. Tax normally falls due as soon as the investor can dispose of the rewards. Selling the Bitcoin received for euros is not a requirement.

That creates a particular risk for investors. The tax is calculated on the euro value at the moment of receipt. If the Bitcoin price falls afterwards, the tax bill can exceed the value the coins still hold later on.

What is Bitcoin lending?

In Bitcoin lending, the investor hands over coins for a limited period to a platform, a company, a borrower or a decentralised protocol. A payment is made in return.

Depending on the product, the Bitcoin made available may be used to:

• fund loans to other users,
• supply trading positions with liquidity,
• provide Bitcoin to institutional market participants,
• fund a centrally managed credit pool,
• provide liquidity inside a DeFi protocol.

The payment can be made in Bitcoin, stablecoins, other tokens or fiat currency. It is often credited to the platform account daily, weekly or monthly.

The Austrian Income Tax Act explicitly captures payments for making cryptocurrencies available as ongoing income from cryptocurrencies. The finance ministry names interest from lending cryptocurrencies as well as consideration for providing crypto assets to liquidity and credit pools.

Bitcoin lending is generally taxed at the point of receipt

The decisive moment is not the later sale of the lending rewards but their receipt. All ongoing crypto income has to be valued at the moment it reaches the investor.

An asset is generally treated as received once the recipient can dispose of it in legal and economic terms. On a lending platform, that may be the point at which the payment is credited to the user account and the investor can withdraw it, swap it, transfer it or lend it out again.

A payout to a bank account is not necessary. A credit in Bitcoin or another crypto asset can already amount to taxable income.

Typical moments of receipt include:

• the daily credit to an accessible platform account,
• the monthly payout to a wallet,
• the allocation of freely transferable reward tokens,
• the automatic credit with immediate reinvestment,
• the payout at the end of a fixed lending term.

Whether a payment that is merely displayed as a figure, without being available yet, has already been received depends on the contractual terms. Where the investor can neither dispose of the coins nor demand their payout, receipt for tax purposes may occur only later.

A sale for euros is not required for the first tax charge

A common misconception holds that crypto gains only become taxable once money lands in a bank account. That does not apply to lending.

Ongoing income is taxed on its value at the moment of receipt. As a rule it makes no difference whether the investor:

• sells the Bitcoin received for euros straight away,
• leaves it sitting on the platform,
• transfers it to a hardware wallet,
• lends it out again automatically,
• swaps it for another cryptocurrency.

The Austrian finance ministry states explicitly that for ongoing crypto income the value of the cryptocurrencies or other payments received at the moment of receipt forms the taxable base.

How the taxable Bitcoin lending income is calculated

Where lending interest is paid in Bitcoin, the amount received has to be valued in euros at the moment of receipt. The reference is generally an available price from a crypto exchange. If no exchange price is available, the price quoted by a cryptocurrency dealer can be used.

This euro value serves two purposes:

• It forms the immediately taxable ongoing income.
• It becomes the tax acquisition cost of the coins received.

The Austrian Cryptocurrency Ordinance prescribes this valuation explicitly. A valuation carried out as part of a capital gains tax deduction is generally binding for the assessment as well.

Example: lending income paid in Bitcoin

An investor lends Bitcoin through a platform. In June the payment amounts to 0.0005 BTC. At the time of the credit the Bitcoin price stands at 60,000 euros.

The calculation runs as follows:

Payment received: 0.0005 BTC
Bitcoin price at receipt: 60,000 euros
Taxable income: 30 euros
Tax at 27.5 percent: 8.25 euros

Those 30 euros also count as the acquisition cost of the 0.0005 BTC received.

The investor therefore has to account for 8.25 euros of tax even though no euros were received and no coins were sold.

A second calculation can follow when the coins are sold

Taxation at the moment of receipt settles the ongoing lending income only. If the value of the Bitcoin received changes afterwards, a further gain or loss arises on the later sale.

Continuing the example:

• value of the Bitcoin received at receipt: 30 euros
• later disposal: 45 euros
• taxable disposal gain: 15 euros
• additional tax at 27.5 percent: 4.13 euros

The 30 euros are not taxed a second time. They form the acquisition cost. What is taxed on the sale is generally only the increase in value of 15 euros that arose afterwards.

If the value instead drops from 30 to 20 euros, the later disposal generally produces a loss of 10 euros. That loss can be set against certain other investment income within the statutory loss offset rules.

Falling prices can create a liquidity problem

Immediate taxation on the value at receipt can turn awkward when the Bitcoin price drops sharply after the credit.

An example:

• lending rewards at receipt: 10,000 euros
• tax at 27.5 percent: 2,750 euros
• value of the rewards when the tax falls due: only 5,000 euros

The original tax charge does not shrink automatically because the Bitcoin price fell later. The loss in value is generally recognised only once it is realised for tax purposes.

If the investor later sells the coins for 5,000 euros, that produces a loss of 5,000 euros against acquisition costs of 10,000 euros. Whether the loss can be used in full depends on whether suitable positive investment income is available in the same period for an offset.

Investors should therefore not assume that lending income is fully available for reinvestment. Part of the value may be needed to fund the tax that follows.

The special tax rate of 27.5 percent generally applies to lending

Ongoing income from cryptocurrencies is subject in Austria to the special tax rate of 27.5 percent. Crypto income therefore does not usually push up the progressive rate applied to the rest of an investor's income.

That typically holds for publicly offered lending products from exchanges and crypto service providers, provided the activity stays within private assets and does not go beyond straightforward asset management.

The 27.5 percent rate generally covers both:

• the ongoing lending payments,
• and later realised increases in value of the coins received.

An exception can apply to private cryptocurrency loans. Where the underlying agreement was not publicly offered in legal and factual terms, the income can fall under the progressive income tax tariff. Depending on total income, that rate can be lower or considerably higher than 27.5 percent.

The label «staking» offers no shelter from the lending tax

Many platforms market interest-bearing crypto products as staking even though no coins are technically deployed to validate a blockchain. In practice the assets are often made available to the platform or to other market participants.

Genuine, classic staking is treated differently in Austria. Where new cryptocurrencies are acquired by participating in transaction processing or block validation, no tax generally arises at the moment of receipt. The coins received are instead recorded with acquisition costs of zero, so the entire sale proceeds can become taxable on a later disposal.

This exception applies only to actual staking. The finance ministry warns explicitly that products merely described as staking can amount to lending for tax purposes. Where the arrangement is economically a supply of cryptocurrencies for consideration, the payment is taxed on receipt.

What matters is therefore the substance rather than the product name, and in particular:

• Who can dispose of the Bitcoin during the term?
• Are the coins deployed for blockchain validation?
• Does the platform obtain the economic use of the assets?
• Is there a claim to repayment in Bitcoin of the same type and amount?
• Is a fixed or variable return promised?
• Does the investor carry a credit or counterparty risk?

An offer labelled Bitcoin staking warrants particularly close inspection, because Bitcoin itself uses no classic proof-of-stake mechanism.

DeFi and liquidity pool income can also count as lending

The Austrian rules are not confined to centrally managed crypto exchanges. Payments from decentralised credit and liquidity pools can equally be ongoing crypto income.

The finance ministry names consideration for providing cryptocurrencies to liquidity or credit pools as a possible case in point. The term liquidity mining is often used for this.

The tax treatment of decentralised products can be more complex, however. Depending on the protocol, the user receives for example:

• ongoing reward tokens,
• an interest-bearing claim against the protocol,
• liquidity pool tokens,
• a token whose value rises continuously,

several different payments at the same time.

Not every increase in the value of such a token is automatically an ongoing receipt. In some cases the income arises only on redemption, exchange or disposal of the claim. The technical and legal construction of each protocol therefore has to be analysed individually.

Depositing the Bitcoin is not the same as the interest earned

Transferring Bitcoin into a lending product has to be distinguished from the taxation of the ongoing rewards.

Under an ordinary supply arrangement, the investor obtains a claim to repayment of the Bitcoin or of a corresponding amount. Austrian law includes repayment claims arising from the supply of cryptocurrencies within the definition of cryptocurrency.

Simply creating such a repayment claim therefore does not automatically trigger taxation of the entire Bitcoin gain accrued up to that point. The ongoing income generally arises through the additional payment received.

The precise assessment depends on the contract. Where the user transfers Bitcoin definitively in exchange for a different kind of token, a security, a fund unit or another asset, a taxable swap can arise instead of a mere lending transaction.

Automatic reinvestment does not necessarily prevent receipt

Many platforms credit the rewards and immediately lend them out again. The user then sees an interest-bearing balance that grows daily or weekly.

Automatic reinvestment does not necessarily mean that no tax arises. Where the investor first held legal and economic control over the payment and it is then reinvested, two events can exist for tax purposes:

• receipt of taxable lending income
• a fresh supply of the coins received

Whether control genuinely existed depends on the contractual terms. Among other things it matters whether the user could switch off the automatic reinvestment, withdraw the rewards or otherwise dispose of them. Receipt for tax purposes generally requires both legal and factual control.

What applies to a fixed lock-up period?

Fixed-term products often lock up Bitcoin for a defined period. The platform may display the payment continuously while paying it out only at the end of the term.

Merely displaying expected income is not necessarily a receipt for tax purposes. Where the user can neither transfer nor withdraw the coins on display and holds no enforceable claim to immediate disposal, receipt can generally occur only on release or maturity.

The picture can differ where the platform credits the rewards irrevocably and merely delays the payout for technical reasons. The question cannot be answered on the strength of the words locked or fixed alone.

Investors should keep the terms and conditions along with their account statements. These should show:

• when the claim arises,
• when the rewards are credited definitively,
• when they become available,
• whether they can lapse early,

whether a payout is possible during the term.

Legacy holdings can become more complicated through lending

Bitcoin acquired up to and including 28 February 2021 generally counts as legacy assets. It falls outside the newer Austrian crypto tax regime to begin with.

Where such legacy holdings are used after 28 February 2022 to generate ongoing crypto income, the newer regime already applies to the rewards produced. The lending payments received count as new assets.

That means:

• The original legacy Bitcoin holding still has to be examined separately.
• The lending rewards derived from it are generally taxed on receipt.
• The reward coins count as newly acquired cryptocurrencies for tax purposes.
• Their later sale generally follows the rules for new assets.

The use of older Bitcoin in a lending product should be documented carefully. Depending on how the contract is drafted, it may also need to be examined whether the supply affects the previous tax classification of the original holding.

Austrian or foreign provider?

Where a domestic party is obliged to withhold, the capital gains tax can be deducted by the provider and paid directly to the tax office. For investment income arising after 31 December 2023, certain Austrian debtors and crypto service providers are generally required to withhold. Once a correct deduction has been made, income tax is usually settled.

Since the 2025 calendar year, Austrian withholding agents also have to supply standardised tax reporting for crypto income on request. Among other items, this can set out ongoing income from supplying cryptocurrencies.

Foreign platforms frequently apply no Austrian withholding at all. Investors resident in Austria for tax purposes then generally have to determine the income themselves and declare it in their income tax return.

The location of the platform does not remove the Austrian tax liability. What counts above all is where the investor is resident for tax purposes and which state has taxing rights under any applicable double taxation treaty.

Foreign withholding tax can play a role

In cross-border lending, states other than Austria can also raise claims. For the purposes of double taxation treaties, the finance ministry generally classifies payments for the supply of cryptocurrencies for consideration as interest.

Under the OECD model treaty, the recipient's state of residence generally has the taxing right. The source state can hold a limited taxing right in addition. Which withholding rate applies in practice, and whether a foreign tax can be credited in Austria, depends on the specific double taxation treaty.

With foreign platforms, investors should therefore also check whether:

• withholding tax was deducted,
• a tax certificate is available,
• the relevant double taxation treaty allows a credit,

a refund application abroad is required.

What happens if a lending platform becomes insolvent?

Bitcoin lending carries economic as well as tax risk. Depending on the structure, the investor transfers coins to a platform and holds nothing more than a claim to repayment.

Where lending income has already been recognised for tax purposes and the platform later loses the coins or becomes insolvent, the original tax charge does not fall away retroactively. Whether a subsequent default on the claim can be recognised as a tax loss depends on the precise legal structure of the claim and on the loss offset rules.

A situation is particularly awkward where:

• rewards were taxed at high prices,
• the coins could not be withdrawn,
• the Bitcoin price then fell,

the platform later became unable to pay.

Recognition of a tax loss should not be assumed in such a case without an individual review.

Commercial activity or private asset management?

Treatment at the special tax rate generally requires the lending to take place within private asset management.

Where the activity goes beyond that in nature and scale, income from a trade or business can arise. The finance ministry names commercial crypto trading and commercial mining as possible cases in which the progressive income tax tariff applies. The distinction is always drawn on the specific facts.

A large sum invested does not by itself turn private lending into a business. Relevant factors can include the organisation, the sustained nature of the activity, its scale, the use of outside capital and participation in general commercial dealings.

Which data investors should document for Bitcoin lending

For every lending platform or protocol, at least the following information should be stored:

• type and amount of the Bitcoin supplied,
• date of deposit and repayment,
• contractual terms of the lending product,
• term and cancellation options,
• date of each reward credit,
• amount of the payment in Bitcoin or other tokens,
• euro price at each moment of receipt,
• price source used,
• capital gains tax withheld,
• acquisition costs of the reward coins received,
• later sales or swaps,
• platform fees,
• wallet addresses and transaction IDs,
• tax reports and account statements,

foreign tax certificates where applicable.

Daily rewards can produce a large number of individual taxable receipts. Suitable crypto tax software can make the analysis easier. Its results should nevertheless be reconciled with the actual platform data and with the legal structure of the product.

Conclusion: Bitcoin lending interest is taxed on receipt

Bitcoin lending can generate ongoing taxable income in Austria before a single satoshi has been sold for euros. What generally counts is the moment at which the investor gains legal and economic control over the payment.

The euro value of the Bitcoin received is then:

• recorded as ongoing crypto income,
• generally taxed at 27.5 percent,

and stored at the same time as the acquisition cost of the reward coins.

If the price climbs further from there, an additional taxable gain can arise on the later sale. If it falls, the tax loss usually only crystallises on a later realisation.

Particular attention is required with:

• automatically reinvested rewards,
• fixed lock-up periods,
• foreign lending platforms,
• credit products marketed as staking,
• DeFi and liquidity pool models,
• legacy Bitcoin holdings,
• private crypto loans that were not publicly offered,
• missing historical price and transaction data.

Investors should therefore document more than their deposits and withdrawals. For the tax calculation, every single available reward credit matters, including the euro value it carried at the time.
