Get a crypto portfolio tax-ready by completing transaction history, resolving Blockpit warnings, and improving data quality before CARF.
With the tax deadline approaching and new regulations like CARF and DAC8 increasing transparency around crypto reporting, proper documentation of your portfolio is more important than ever.
Use quieter market phases to review your data in Blockpit: import all exchanges and wallets, resolve open tips, and improve your Account Health. This helps ensure that your portfolio is fully documented and that your tax report can be generated accurately—without unnecessary tax risk.
In short: If you review your transactions now, preparing your tax report later becomes almost automatic.
Regulation in the crypto space is becoming stricter. With CARF, transactions from crypto exchanges and wallet providers are already being recorded today and will be automatically reported to tax authorities starting in 2027. Exchanges and platforms are required to report relevant transaction data.
This means that incomplete or inconsistent transaction histories will become much harder to explain in the future.

Quick checklist:
Goal: Your portfolio in Blockpit should reflect your entire crypto history. Only then can your tax report be generated accurately. For all integrations, you can find detailed step-by-step guides in the Blockpit Help Center explaining how to set up connections and import your data.

Once your transactions are imported, it’s worth checking the tips in your Blockpit account.
Tips are automatic indicators that highlight when something in your transaction history is incomplete, unclear, or inconsistent. They help you identify potential problems early and improve the quality of your data.
The more tips you resolve, the higher your Account Health becomes. This metric represents the percentage of transactions without unresolved tips, and ideally it should be as close to 100% as possible. High data quality ensures that your tax report can be calculated accurately.

In this case, Blockpit applies fallback logic to calculate your report. While the report remains usable, it may result in a higher tax burden rather than a lower one. By resolving tips, you can often improve the accuracy of your tax report and potentially reduce your tax liability.</div></div>
Below are the four most common tips you may encounter in Blockpit—and how you can resolve them quickly.
This tip appears when a transaction does not yet have a label, meaning Blockpit cannot clearly determine what type of transaction it is. While many transactions are labeled automatically, some cases require manual classification.
Typical examples:
How to fix it:
If several transactions belong together, you can also edit them together or merge them to correctly represent the event.
This tip occurs when the balance reported by the exchange or wallet (Synced Balance) does not match the balance calculated from your transactions (Calculated Balance). It usually indicates that some transactions may not have been imported correctly.
This commonly happens when:
How to fix it:
The “Missing History” tip appears when an asset leaves your account even though, according to your transaction history, it was never recorded as being in your balance.
Example:
You see an outgoing transaction of 1 BTC with the message “Missing history of 1 BTC”. This means that the previous transaction where 1 BTC entered the integration is missing.
This often happens when:
How to fix it:
This tip appears when Blockpit cannot determine a price or market value for a transaction.
This can happen for example with:
