'Plusvalía del Muerto' (Spanish Inheritance Step-Up)

Definition

The 'plusvalía del muerto' (literally, 'the dead person's capital gain') is the colloquial name for a tax advantage in Spanish inheritance law: the latent capital gain on a deceased person's assets — the appreciation of their portfolio, including their Bitcoin — is not taxed in the deceased's personal income tax (IRPF). It is enshrined in Spain's IRPF law, which states that no capital gain or loss arises from transfers of assets upon death (the 'plusvalía del muerto' goes untaxed).

Inheriting versus gifting. This is the key difference. If a person gifts their Bitcoin to their children during their lifetime, the donor may have to pay IRPF on the accumulated capital gain (the difference between cost and value at the time of the gift). If, instead, those same bitcoins pass by inheritance, that appreciation is never taxed: for a Bitcoin portfolio that has appreciated heavily, the difference can be enormous. In both cases, the recipient still pays Spain's Inheritance and Gift Tax, which varies by autonomous region.

Why it matters for Bitcoin. Given Bitcoin's volatility and long-term appreciation potential, the effect is amplified: planning the transfer — with a will, a succession plan, and a secure key-handover scheme — is not just about preventing heirs from losing access; it is also a decision with significant Spanish tax consequences. This is not tax advice: confirm your situation with a professional.
