Liquidity provision on Uniswap and Curve: Spanish tax treatment
On deposit: AEAT treats it as a "permuta" (taxable swap) — you "sell" ETH+USDC and "buy" LP tokens. Capital gain/loss applies based on FIFO acquisition cost.
Pool rewards: Trading fees and governance tokens received = capital income at market value on receipt.
On withdrawal: Another taxable swap — "sell" LP tokens, "receive" underlying tokens. Impermanent loss = real capital loss.
Global platforms like Koinly detect liquidity events but don't apply Spanish-specific tax rules. kointax has DeFi-specific support for Spanish regulations.
