Crypto inheritance in Spain: taxes and procedures
Inheritance tax (ISD): Based on market value at date of death. Regional tax (varies by autonomous community). Direct heirs often get 99% bonification in most regions.
Critical IRPF point (step-up basis): Inherited crypto acquisition cost = market value at date of death (not original purchase price). This means future gains are calculated from the much higher inheritance value.
Example: BTC bought at €10,000, inherited at €60,000. Sold at €70,000. Capital gain = €10,000 (not €60,000).
kointax correctly handles inherited crypto with the step-up basis for future sale calculations.
