If you open a transaction in Transactions, the advanced details show you two things:
📒 Ledger Details: how the transaction affects your holding of the asset in this integration
🧾 Tax Details: how Blockpit values the transaction for tax purposes, i.e. proceeds, cost basis and gain or loss
This way you find out why a balance turns negative or how a gain in your tax report comes about.
Ledger Details: What happens to my balance?
The Ledger Details show every balance change of the transaction and the new total balance after it.
💡 Example: In a Trade from ETH to USDC, the ETH balance decreases by 0.2402 ETH, while 719.7281 USDC come in.
The columns
▸ Label: inflow or outflow, for example Sell or Buy
▸ Integration: the exchange or wallet the transaction comes from
▸ Asset and Asset Type: which asset is affected and which category it belongs to, for example Crypto
▸ Change: by how much the balance changes, for example −0.2402 ETH
▸ Balance: the new total balance of the asset after this transaction
⚠️ Caution: A negative balance means that earlier transactions are missing or one is duplicated. Check whether all deposits, purchases and transfers have been imported.
Tax Details: How is the transaction valued?
For every outflow, the Tax Details show at what value you sold, what you had paid for it and whether this results in a taxable gain or loss.
✨ Blockpit Plus: The Tax Details are available with an active Blockpit Plus subscription.
💡 Example: You sell 0.2402 ETH for €615.90. The cost basis of this amount was €814.78.
€615.90 proceeds − €814.78 cost basis = €198.88 loss
Below, you see the tranches that make up the cost basis, in this case according to the FIFO principle (first in, first out).
The columns
▸ Price: euro price per unit at the time of the transaction, mostly taken from CoinMarketCap or CoinGecko
▸ Value: basically quantity × price. For trades, Blockpit values the incoming or the outgoing asset depending on the tax country (see below). This value becomes the proceeds.
▸ Proceeds: the value at which the asset was disposed of. You can change it afterwards via Update asset values.
▸ Cost Basis: the sum of the acquisition costs from earlier purchases (tranches). It also depends on the label: Airdrop sets it to €0, Non-Taxable (In) to the value at the time of the transaction (quantity × price).
▸ Profit/Loss: proceeds − cost basis, gains in green, losses in red
▸ Tranche Display: A click on the arrow shows which earlier purchases go into the calculation, in the order of your method (FIFO or average cost basis)
▸ Taxable: A check mark shows that the transaction is taxable
ℹ️ Good to know: Here you only see whether the outflow of an asset triggers a gain or loss. Gains from futures and derivatives (label Derivative Gain) are not shown here but in the tax results under Reports.
Why sometimes the incoming and sometimes the outgoing asset counts
Blockpit values all transactions in euros. A Trade has two sides, but only one is valued, so that no value is applied twice or contradictorily. Which side counts depends on the tax country and on the price quality of the assets:
🇩🇪 Germany: In crypto-to-crypto trades, mostly the incoming asset
🇦🇹 Austria: mostly the outgoing asset. Since crypto-to-crypto trades are tax-exempt there, this only plays a minor role now (keyword: average cost basis).
💶 Trade directly against euros: The euro amount is the value
Blockpit uses hourly and daily closing prices. If a value is wrong, you correct it via Update asset values.
⚠️ Typical misunderstandings
✗ A loss in the Tax Details means the Trade was bad → only the cost basis of the disposed quantity counts, not your overall result
✗ Looking for derivative gains here → they are in the tax results under Reports
✗ Taking a cost basis of €0 for an error → for airdrops that is intended; otherwise it points to a missing history
