CryptoTax determines your cost basis using FIFO (First-In-First-Out) lot matching for your Belgian tax return.
FIFO lot matching
CryptoTax processes your taxable actions per asset in chronological order. For each disposal, the engine assigns the volume to the oldest open acquisition lots first (FIFO).
Cross-chain tracking
The system links bridge deposits and withdrawals to each other to maintain lot continuity across blockchain networks.
Cost basis calculation
The cost basis is calculated per disposal using the exact lot pieces consumed by FIFO, not as a rough aggregated calculation.
Export details
The CSV for disposals contains lot-level data with timestamps, holding periods, costs and gains/losses.
Common FIFO mistakes
Many users make common FIFO mistakes in their tax return. Make sure you understand your disposals before you file your return.
