Staking in Spain: the Koinly misclassification problem
Spanish AEAT rule: Staking rewards = "rendimientos del capital mobiliario" (capital income), valued at market price at receipt, placed in specific IRPF boxes.
Koinly's approach: Classifies as generic "income" — doesn't specify which Spanish IRPF box to use and doesn't differentiate from capital gains.
Impact: Filing in wrong IRPF box (same tax rate, wrong category) can trigger AEAT requests.
Solution: kointax automatically classifies staking as capital income in the correct IRPF boxes.
