Buying property with Bitcoin in Spain: taxes
IRPF (for buyer): Using BTC to pay = deemed BTC sale at market value. Capital gain = market value on transaction day - original purchase price.
Example: Bought BTC at €10,000, pays property when BTC = €60,000 → €50,000 capital gain → pay ~28% IRPF on that gain.
ITP (Property Transfer Tax): Also due. Property value = market value of BTC delivered. Rate: 6-10% depending on Autonomous Community.
Documentation: Notary must document transaction. Price expressed in euros even if paid in crypto.
