Bitcoin24 and Your Crypto Tax Obligations
Bitcoin24 (bitcoin24.de) was a pioneering German Bitcoin exchange that allowed users to buy and sell Bitcoin as far back as 2011–2013. Operated from Germany, it was one of the first domestic trading platforms for German crypto users before larger international exchanges became dominant. Bitcoin24 permanently closed in April 2013.
Despite the exchange being long offline, any Bitcoin trades you executed on bitcoin24.de in 2012 or 2013 may still have tax implications today — particularly if those Bitcoins were held and later sold on other platforms. Accurate records of your original cost basis from Bitcoin24 are essential for calculating your overall crypto tax position.
CoinTracking supports Bitcoin24 import via JSON export:
- If you saved your old JSON export code from bitcoin24.de, paste it directly into CoinTracking\'s Bitcoin24 import page
- All historical trades and transactions are automatically parsed and processed
- Your Bitcoin24 data can be combined with imports from any other exchange or wallet in one unified portfolio
- CoinTracking applies German tax rules, including the one-year holding period exemption (§ 23 EStG)
Crypto Tax Basics: What Bitcoin24 Users Need to Know
Bitcoin24 was a German exchange serving primarily German-speaking users. The tax rules below focus on Germany, where the vast majority of Bitcoin24 users were based — but CoinTracking supports tax reporting for all jurisdictions.
Germany: one-year holding period exemption
In Germany, crypto gains are taxed as private disposal income under § 23 EStG (Einkommensteuergesetz). Gains on assets held for longer than one year are completely tax-free. For assets held under one year, your personal income tax rate applies — up to 45%. Annual gains below €1,000 are also exempt from tax. German users declare crypto gains in Anlage SO of their annual income tax return. Given that Bitcoin24 closed in 2013, most historical Bitcoin purchased there has long since passed the one-year holding threshold — but exact calculations depend on your individual transaction history.
Cost basis matters even for old trades
The cost basis of Bitcoin you acquired on bitcoin24.de in 2012 or 2013 directly affects your taxable gain when you later sell that Bitcoin — regardless of which exchange you ultimately used for the sale. CoinTracking tracks the acquisition cost from your Bitcoin24 JSON import and carries it forward through your entire transaction history, ensuring accurate gain calculations even years after the original purchase.
Record-keeping obligations
German tax law requires that you retain records supporting your tax return. For historical crypto trades, this means preserving your Bitcoin24 JSON export or other evidence of your original Bitcoin purchases. CoinTracking stores and processes this data, generating a complete audit trail that you can present to your Finanzamt if required.

Are Bitcoin24 Transactions Taxable?
In Germany and most EU countries, crypto is treated as an asset: disposing of it triggers capital gains tax. The one-year holding rule in Germany is key for Bitcoin24 users.
Taxable Events
- Selling Bitcoin for fiat (EUR, USD, etc.) within one year of purchase
- Swapping or trading Bitcoin for other crypto within one year
- Using Bitcoin to pay for goods or services
- Selling Bitcoin held for less than one year (Germany)
Not Taxable
- Buying and holding Bitcoin on Bitcoin24
- Selling Bitcoin held for more than one year (Germany)
- Transferring Bitcoin between your own wallets
- Annual gains below €1,000 total (Germany, Freigrenze)
Tax treatment varies by country. CoinTracking applies the rules for your selected jurisdiction automatically.
How to Calculate Your Bitcoin24 Taxes
Even a small number of Bitcoin trades from 2012 or 2013 can have a significant tax impact if the Bitcoin was later sold at a much higher price. Accurately calculating your cost basis from your Bitcoin24 trades is the foundation of a correct tax return — especially in Germany, where the one-year holding period determines whether gains are tax-free or taxable at your income tax rate.
CoinTracking imports your complete Bitcoin24 JSON export, matches your original purchase cost to every subsequent disposal, and applies the correct cost-basis method (FIFO, LIFO, HIFO, and others). The result is a clear breakdown of taxable and tax-free gains for each year — including an Anlage SO report formatted for the German Finanzamt.
If you used multiple exchanges in addition to Bitcoin24, CoinTracking consolidates everything into one unified portfolio with a single tax report — saving you hours of manual calculation.

How to Create Your Bitcoin24
Tax Report with CoinTracking
Three steps from JSON import to a tax report your Finanzamt will accept.
Import your Bitcoin24 JSON export
In CoinTracking's Import section, search for "Bitcoin24" and paste your old JSON export code from bitcoin24.de into the import field. All historical trades are processed automatically.
Review your transactions
Open Reports → Validate Transactions. CoinTracking flags missing cost basis entries, duplicate imports and price gaps so your final report is accurate.
Generate and export your tax report
Select Germany (or your country) and the relevant tax year. CoinTracking generates an Anlage SO report or jurisdiction-specific PDF/Excel — ready for your Finanzamt or accountant.
No. Bitcoin24 closed in April 2013 and is no longer operating. However, if you still have an old Bitcoin24 JSON export file from bitcoin24.de, you can import it into CoinTracking. CoinTracking will process your historical Bitcoin24 trades and generate a compliant tax report for your jurisdiction — including Germany and other EU countries.
Bitcoin24 used a JSON export format. If you saved your JSON export code from the now-closed bitcoin24.de, you can paste it directly into CoinTracking's Bitcoin24 import page. Navigate to the Import section in CoinTracking, search for "Bitcoin24", and paste your JSON code into the text field provided. CoinTracking will automatically parse and import all your historical trades.
Yes. In Germany, capital gains from crypto disposals are taxable under § 23 EStG regardless of when the trades occurred. However, gains on assets held for longer than one year are completely tax-free. Since Bitcoin24 closed in April 2013, any Bitcoin you sold through the exchange in 2012–2013 may be subject to a statute of limitations — but this depends on your individual circumstances. Consult a qualified tax advisor for guidance on older transactions.
DAC8 is an EU directive that requires licensed crypto exchanges to report user transaction data to national tax authorities. Bitcoin24 closed in 2013 — long before DAC8 was introduced. However, your overall obligation to declare historical crypto gains from German exchanges remains. Tax compliance for all past trades is your personal responsibility. CoinTracking helps you calculate and document any remaining tax obligations from your Bitcoin24 transaction history.
If you no longer have your JSON export from bitcoin24.de, you may not be able to recover the data directly from the exchange — the site has been closed since April 2013. However, you can manually enter your Bitcoin24 trades in CoinTracking using the manual entry feature. If you have bank statements or other records from that period, these can help reconstruct your trading history for tax purposes.
CoinTracking directly supports the Bitcoin24 JSON import format, so if you have your old export file, importing is straightforward. Once your historical trades are in CoinTracking, it calculates gains and losses using FIFO, LIFO, HIFO, and other cost-basis methods, applies German tax rules (including the one-year holding period exemption), and generates an Anlage SO report for your income tax return. You can also combine your Bitcoin24 history with data from all your other exchanges and wallets in a single portfolio.
