Bitcoin as corporate reserve in Spain: Corporate Tax
Corporate Tax (IS): 25% general rate (15% for startups in first years).
Accounting treatment (under Spanish PGC):
- Intangible asset: Recorded at acquisition cost. Not amortized. Value decline → impairment (deductible). Value increase → NOT recognized (prudence principle).
- Financial asset: At fair value. Variations through P&L or equity.
Selling corporate Bitcoin: Gain = sale price - acquisition cost → taxed at 25% IS. No short/long-term distinction in IS.
Corporate staking rewards: Income of the period → taxed at IS rate.
