Airdrops in Spain: tax treatment
Spain's AEAT rules:
- Airdrops = "rendimientos del capital mobiliario" (capital income) at receipt
- Taxed at market value when received (even if "free")
- Acquisition cost for future sale = market value at receipt
- If no market value at receipt, taxation deferred until value exists
Example: Receive 100 tokens at €0.50 = €50 capital income now. Sell at €2 = €150 capital gain (not €200, because €50 was already taxed)
Koinly classifies airdrops as "income" but doesn't specify the correct Spanish IRPF box. kointax automatically classifies them correctly.
