Polygon (MATIC/POL) in Spain: taxation

MATIC → POL migration (2023): 1:1 swap. Conservative position: treat as swap with capital gain/loss at migration market value. Some argue no tax event (technical upgrade).

POL staking: Rewards = capital income at market value when received. Taxed at base del ahorro (19-28%).

DeFi on Polygon (QuickSwap, Aave, etc.):

  • Swaps: capital gain/loss
  • Liquidity provision: potential tax event
  • Farming rewards: capital income

Gas fees: POL payment = disposal event if POL has unrealized gains.

kointax natively supports Polygon network, importing all wallet transactions.
