1. General Questions About Crypto Taxes in Germany

Do I have to show my entire transaction history to the tax office?

‍No, initially it’s enough to report your taxable gains and losses – as shown in the Blockpit tax report. Usually, that’s sufficient. However, some tax offices may later request to see your full transaction history. That’s why you should be able to present it if needed.

Our tip: Keep your tax report and transaction data ready – this way, you're prepared for any follow-up questions.

Do I have to file a crypto tax return if I haven’t sold anything – or made less than €1,000 in profit?

‍No. In Germany, you only need to declare crypto gains in your tax return if they are taxable, meaning:

• You sold coins at a profit within one year, and
• The profit exceeds the €1,000 exemption limit, or
• You had income from staking, lending, airdrops, etc.

You do not have to declare:

• Tax-free sales of long-term holdings (held over 1 year)
• Profits below the €1,000 exemption threshold

But beware: If you realize large amounts tax-free (e.g., buying a house with old BTC gains), the tax office may still request documentation.

Therefore: Keep clean records – e.g., with a Blockpit tax report.

Tip: You should also report losses – even if they’re not taxable. Only then can you carry them forward to the next tax year and offset them against future gains. If you don’t report the losses, you can’t claim them later.

How quickly can I be classified as a commercial trader?

‍There’s no fixed threshold that defines you as a commercial trader. It depends on your individual case and how your tax office assesses it.

Examples:

• If you trade intensively, regularly, and with profit intent (e.g., hours of daily trading like a pro), you might be classified as commercial even with few trades.
• If you trade automatically or only occasionally, you usually remain in the private sphere – even with many transactions.

Important:
Never trade on behalf of others! If you manage other people’s money (e.g., friends or family) and trade with it, you risk being classified as a commercial trader – or even a financial services provider, which would require a license!

Also, shared accounts (e.g., with a spouse or for children) quickly lead to tax complications.

Tip: If you trade frequently and regularly, speak to a tax advisor early to be on the safe side.

Could the government abolish the one-year holding period – and apply it retroactively?

‍No, a retroactive change to the holding period would usually be unconstitutional.

In Germany, the principle of legal certainty applies: If you bought a cryptocurrency when the one-year holding period was in effect, the government cannot change that rule retroactively to your disadvantage.

Specifically:
If you bought Bitcoin in January 2024 and sell it in February 2025, the old one-year holding rule still applies – even if the law changes later.

Only in extreme exceptions (e.g., tax fraud or legal loopholes) might the government try to act retroactively – but this hasn’t happened in the crypto space and would be legally controversial.

How bad is it if I forget something on my tax return or need to submit something later?

‍Don’t panic – mistakes or omissions can usually be corrected without issue.

Best approach: Contact your tax office proactively or ask a tax advisor what to do. In most cases, a correction or voluntary disclosure is enough – you just have to pay the missing tax, usually without penalties.

Important: The earlier you reach out, the better. If you take initiative, it shows willingness to cooperate – which is usually viewed positively by the tax office.

If exchanges are required to report in 2026 – does that make tax returns obsolete since the tax office already has the data?

‍No – your own tax return remains mandatory, even if exchanges report tax-relevant data to the authorities starting in 2026 under DAC8 (EU) or CARF (international).

Important to know:

• The report does not replace a tax return.
• You are still responsible for calculating and reporting your crypto gains correctly.
• Exchange data is often incomplete.
• Authorities see only individual platforms – not your overall strategy (e.g., wallet transfers, losses, tax-free coins, etc.).

The tax office will cross-check your report.
If you don’t report or report incorrectly, the tax office can compare your data with exchange submissions – and initiate estimates, inquiries, or legal action.

Conclusion:
The new reporting obligations increase the pressure to file correctly – but they do not exempt you from your duty to file your crypto taxes yourself. If you keep clean records, you have nothing to worry about.

2. Specific Tax Cases (Staking, Mining, Gifts, Lending, Losses)

Do I have to declare staking rewards in my tax return, even if I haven’t sold anything?

‍Yes – staking is taxable upon receipt, not upon sale.

This means: As soon as you claim staking rewards, you must declare them as other income – regardless of whether you sell them afterwards or not.‍

Important: If your annual earnings are below the exemption limit of €256, you do not have to declare them. If they exceed this amount, you must report the rewards in your tax return – even without a sale.‍

Update from the BMF: Even if you don’t manually claim staking rewards, they are considered automatically received by December 31st of each year – and are therefore taxable.‍

Tip: Keep clean documentation of your inflows and staking protocols – with Blockpit, this is done automatically.

When are purchased and staked tokens tax-free?

‍The originally purchased coins (e.g. 1 ETH on 01/03/2024) are tax-free if they are held for at least one year and then sold.‍

Important for staking: The staking rewards you receive in the meantime (e.g. 0.001 ETH daily) are each considered new inflows. → For each individual reward tranche, a new one-year holding period begins from the date of receipt.

Example:
1 ETH purchased and staked on 01/03/2024
Sold on 02/03/2025 → the original ETH is tax-free
The staking rewards are still partially taxable if they are less than 1 year old.‍

Tip: Blockpit automatically shows you holding periods and tax-free sales.

I want to gift BTC to my children – I’ve held the coins for over a year.
‍a) Is the value for the gift calculated at the time of transfer?
b) Does the tax exemption from the one-year holding period automatically carry over to the children?

a) Is the valuation done at the gift date?
Yes. For gift purposes, the market value of your BTC on the day of the gift is used. This is relevant for determining whether you exceed the exemption thresholds (€400,000 per child, every 10 years).

b) Does the tax exemption (holding period) carry over to the children?
Yes, generally it does. If you’ve held the BTC for more than a year, the child inherits your original acquisition date when the gift is made. This means the coins can be sold tax-free immediately – as long as it is not a paid transfer or a special case.
The gift itself may be subject to gift tax if you exceed the exemption threshold – but the sale of the BTC by the child can still be tax-free.

How is mining treated for tax purposes?

‍It depends on the scale:

• Small-scale mining (e.g. via mining pools or occasionally): Earnings are considered other income and are taxable upon receipt – at the market value at the time of receipt.
• Larger-scale mining (e.g. multiple dedicated devices, high electricity usage): Can be classified as a commercial activity. In this case, different rules apply: no holding period, different taxation (e.g. income or corporate tax).
  Important: Blockpit is not intended for commercial users, but for private income tax purposes.

How can I claim a worthless coin for tax purposes?

‍If a coin has no value but you’re still holding it, you cannot claim the loss for tax purposes until it is disposed of.

Here's how to realize the loss:

• Actively dispose of the coin: You must sell or send the coin elsewhere, e.g. to another wallet. Only then is the loss considered realized for tax purposes.

Example: Send the coin to a friend and have them give you €1 symbolically in return. This counts as a sale – and you can declare the loss for tax purposes.
Important: As long as the coin remains in your wallet, it’s not considered “disposed of” for tax purposes – and the loss does not count. Only through actual outflow (e.g. sale or swap) does the loss become real.

3. Blockpit Features & Tax Report

What happens if warnings in Blockpit remain unresolved?

‍Even if not all warnings are resolved, Blockpit still generates a complete tax report. A fallback logic is automatically applied to supplement missing information using a fixed schema:

• For unidentified inflows, it is assumed the coins were acquired at the current market value.
• For unidentified outflows, no taxable event is assumed – meaning no gain or loss is reported.

This is generally in your favor, but not always accurate. Especially for larger amounts, this may cause issues with the tax office if assumptions don’t match reality.‍

Our recommendation:

• Sort warnings by amount – and prioritize resolving transactions with high values.
• For smaller amounts (e.g. under 1% of your portfolio), the fallback logic might be acceptable.
• Ensure the report documents all unresolved warnings and assumptions – this creates transparency for the tax office.
• If unsure or dealing with large sums: clean up the data or consult a tax advisor.

Important: You are responsible for the accuracy of the data. Blockpit assumes no liability for tax consequences resulting from incomplete or incorrect information.

How do I handle dusting attacks in Blockpit?

‍These tiny, unexplained inflows – often from unknown senders – are known as dusting attacks. They usually have no real value and are not the result of an intentional action on your part.

How to classify them in Blockpit:

• Mark as Airdrop: If you received the coins without providing anything in return, classify them as “Airdrop.” They’ll be recorded with €0 acquisition cost – meaning full taxation upon sale.
• Mark as Spam: If it's clear spam or an untradeable token (e.g. suspicious Solana cashback), mark it as spam. In the transaction or asset overview, click the three dots and select "Mark as spam" – these will be fully excluded from tax calculations.

Is there a way to handle dusting transactions in bulk?

‍Yes, to a certain extent. Blockpit allows batch editing of up to 200 transactions at once. Here’s how:

1. Apply filters: Use the filter function in the transaction overview, e.g. filter by asset (“XLM”) or transaction type (“inflow”).
2. Sort by amount: Sort by lowest value – dusting transactions usually appear at the top.
3. Calculate values (if needed): If no value is shown, click "Calculate" first.
4. Select multiple transactions: Use checkboxes to select the relevant rows.
5. Change transaction type: Use the bulk edit menu to label all selected transactions, e.g., as "Airdrop" – done!

Conclusion:
Dusting attacks are annoying but usually harmless for taxes. With proper classification and batch editing in Blockpit, you can remove them quickly – keeping your tax report clean.

Blockpit shows taxable gains even though I held all coins for over a year. What now?

‍If Blockpit classifies your sale as taxable even though you believe all coins were held for more than a year and all transfers are merged, this is usually due to data gaps or incorrect transactions.

Check the following:

• Warnings & data gaps: Look for any warnings in the affected transaction (e.g., “Missing history”). This often indicates that Blockpit can’t trace the original acquisition date and assumes the sale is taxable.
• Check the tranche: Click on the transaction and see which coins (tranche) were sold. Blockpit shows the acquisition date of the tranche. Only coins with a full 1-year holding period are treated as tax-free.
• Wallet / account separation: If your tax-free coins are on a different wallet or exchange than where you sold from, they won’t be used for the sale.

Example:
You sell from Binance, but your tax-free coins are still on your Ledger. Blockpit uses the Binance tranche – which may be taxable.

• Were transfers properly merged? Only correctly matched transfers with complete history count toward the 1-year holding period. → Open the full transaction chain to see if any transfers are missing or unmerged.

Conclusion:
Blockpit calculates correctly – but only if all data is properly imported and transfers are linked. If you can't find the issue, contact support and provide the transaction ID of the affected sales along with relevant screenshots.

Is there an integration with WISO tax software?

‍Yes. You can easily download the WISO tax export (CSV) from Blockpit and import it directly into WISO Steuer.

Tip: Make sure to export the current tax report and do not modify the file before uploading it to WISO. A detailed guide is available here.

How does Blockpit handle the BEST and PAN token merge into Vision – and what are the tax implications?

‍The Bitpanda token merge (BEST + Pantos → Vision) is automatically recognized by Blockpit as a token migration and correctly processed.

Tax treatment:

• No sale involved: It’s a tax-neutral token migration (label: Token Migration), not a taxable trade.
• Holding period preserved: Your original acquisition date and holding period for BEST and PAN are carried over to the new Vision token.
• Cost basis retained: Your original acquisition cost is also retained.

Result: If your BEST or PAN were already tax-free (e.g. held over 1 year), the resulting Vision tokens will also be tax-free when sold.

Why does Blockpit show more crypto than I actually own – even though I used CSV or API?

‍This almost always results from missing or incorrect transaction data.

Step-by-step explanation:

1. Check how the integration was done:
   • API sync (e.g. Binance, Kraken): The “Synced balance” reflects your live balance on the exchange – usually accurate.
   • CSV import: Blockpit calculates the balance based on transactions (inflows/outflows). If any are missing, the balance will be off.
2. Common causes of inflated balances:
   • Missing outflows in the CSV (e.g. missing sales or transfers)
   • Duplicate transactions due to combined CSV + API import
   • Wrong file used (e.g. wrong exchange format)
   • Exchange provides incomplete data
3. How to fix it:
   • Go to the portfolio view in Blockpit and select the affected integration.
   • Check the “Transactions” tab for missing or duplicate outflows.
   • If only a CSV was used: ensure all relevant inflows and outflows are included.
   • If CSV and API were combined: check for possible double entries.
4. Solution:
   • Add missing transactions manually or correct the CSV
   • Delete duplicate transactions
   • If unsure: contact support and provide a screenshot + the original CSV file

Tip: When using CSVs, always double-check that you use the correct template (right exchange and format). When in doubt, ask for help – incorrect data leads to incorrect tax reports.

How do I correctly represent lending protocols like Aave in Blockpit with collateral and debt?

‍Blockpit supports Aave and similar protocols automatically – as long as you connect a suitable wallet (e.g. Ethereum address).

Here’s how the process is handled:

• Collateral deposit (e.g. ETH to Aave):
  → Marked as tax-neutral outflow
  → Moves into an internal “Collateral account”
  → You receive a token in return (e.g. aETH)
• Borrowing:
  → Marked as tax-neutral inflow
  → Funds are available to use
• Received lending tokens (e.g. aETH, cDAI):
  • If tradable:
    → Treated as a taxable trade upon deposit (e.g. BTC → aBTC)
    → Blockpit automatically recognizes and classifies this as a trade
  • If not tradable (pure IOU):
    → Remains tax-neutral
    → Original coin is returned 1:1 after repayment
• Interest / rewards:
  → Taxable as other income upon receipt (similar to staking rewards)

Important: Blockpit automatically determines whether it’s a taxable trade based on token behavior.

Manual adjustment is possible if you or your tax advisor prefer a different interpretation:
→ Open the transaction and change the label (e.g. from “Trade” to “Transfer” or “Tax Neutral”).

Best practices:

• Use a direct wallet integration (e.g. Ethereum address) to import all Aave transactions accurately
• Avoid CSVs for DeFi – they often lack technical details
• If unsure: consult a tax advisor, especially for large amounts or complex protocol flows

Can I delete or replace an existing API integration in Blockpit if the key has expired?

‍Yes – and this is usually the best approach.

Best practice for expired API keys:

• Don’t create duplicates: Only one API integration per exchange should be active. Two integrations for the same exchange will result in duplicate transactions and incorrect reports.
• Update the existing API (recommended):
  • Go to the respective integration in Blockpit
  • Click the three dots → “Edit”
  • Enter the new API key and secret
  • Save – done! Your transaction history remains intact.
• Alternative: Delete and reconnect the integration
  If your API has been inactive for months and transactions are missing (e.g. due to limited API history like on Kraken), it's better to delete the integration and reconnect – all data will then be re-imported from scratch.

Conclusion:
You can easily delete or replace an API integration. Usually, updating the key is enough. Reconnecting only makes sense if there are major data gaps.

Why don’t my staking rewards show up in the tax report?

‍If your staking rewards were correctly imported into Blockpit and fall within the relevant tax year, they do appear in the tax report – specifically:

• As other income (relevant for the €256 exemption limit)
• In the individual transaction overview
• At the end of the report, summed up with other rewards like airdrops, bounties, etc.

Please check: Are the transactions properly labeled and assigned to the correct tax year?

4. General Questions About Blockpit

When will integration XYZ be available in Blockpit? When will the CSV upload for exchange XYZ be added?

‍Whether and when an integration is added depends heavily on user demand.

Tip: In our AI assistant in the app, you can view current feature requests – there, you can vote for integrations or submit new suggestions. The more votes, the higher the chance of implementation.

Until then: Use our manual Excel import template.

What if I can no longer track my crypto transactions?

‍If you're missing data or can't remember exactly what happened, try the following:

1. Reconstruct to the best of your knowledge
Manually enter missing transactions as accurately as you can based on what you still know.
Important: Your entries should plausibly match your current portfolio (no unexplained balances or gaps).

2. Exchange no longer exists? No problem.
If an exchange no longer exists (e.g. FTX, Mt. Gox, QuadrigaCX), you can only estimate the data.
The tax office usually can't access data from these platforms either – your estimate counts, as long as it’s well-documented and reasonable.

3. For larger sums: Consult a tax advisor + include a written explanation
If significant amounts are involved, definitely coordinate with a tax advisor.
Work together to create a cover letter explaining your estimates.
This helps protect you from inquiries or legal risks.

Tip: Even if you can't reconstruct everything – an honest, documented attempt is better than no explanation at all.

How secure is my data with Blockpit? Who can access what?

‍Your personal data (e.g. name, email) is safe with us – we have no interest in storing unnecessary personal information.

Wallets and transactions are only stored because they’re needed for tax calculations. You enter them consciously – they are publicly visible (public keys), but not linked to your name.

Security & privacy at Blockpit:

• No data sharing with the tax office.
  → We’re not a financial institution, so we have no reporting obligation.
  → The tax office gets data directly from exchanges – not from us.
• Hosting in a private cloud in Central Europe.
  → We don’t use Amazon, Microsoft, Google, etc.
  → Everything runs on GDPR-compliant infrastructure.
• ISO-certified security (ISO 27001).
  → We've already been audited by tax authorities.
  → Encryption and security measures are up to date – and often beyond.

Bottom line: Your data is as secure as technically possible with Blockpit. No access by third parties, no sharing – full control remains with you.

Can I use one license to manage multiple people (e.g. myself and my spouse)?

‍No – each person needs their own account and license. Exchange accounts are always tied to individuals (due to KYC), so transactions should not be mixed.

Even if you file taxes jointly, it’s important to keep data separate for tax purposes – otherwise, it may cause traceability issues or problems with authorities.

Can I use Blockpit support if I have a conflict with the tax office?

‍If you have issues with the tax office itself, you must consult a tax advisor – we’re not allowed to provide individual tax advice.

However, if there are questions about how the Blockpit software works, our support team can provide a technical statement to assist.

What do I need to do to use Blockpit for my business?

‍Blockpit is currently developing an export function for businesses. It will allow you to export all transactions including EUR valuations – ready for further processing in DATEV or via third-party tools like steuertools.de.

This feature is expected to launch within the next few weeks or months (as of July 2025).
Until then, you can continue importing your data and preparing everything as usual.
