Koinly problems for crypto tax returns in Spain
Problem 1: FIFO doesn't match AEAT requirements
The Spanish AEAT has specific FIFO criteria for cryptocurrencies that Koinly's generic implementation doesn't always follow.
Problem 2: Doesn't generate Models 172 and 173
Since 2023, many investors must file Model 172 (balances at foreign exchanges) and Model 173 (year operations). Koinly doesn't automatically generate these.
Problem 3: No exact IRPF boxes
Koinly shows gains generically without mapping them to specific IRPF boxes.
Problem 4: Customer support only in English
Problem 5: Prices in dollars
The solution: kointax
kointax resolves all these issues as it was designed from scratch for Spain.
