Cardano (ADA): staking, delegation and taxation in Spain
Cardano is known for its academic approach and lock-up staking system. ADA holders can delegate to stake pools without giving up custody of their tokens and receive rewards every 5 days (every epoch).
How staking works on Cardano
- No lock-up: You can delegate and withdraw whenever you want. Your ADA never leaves your wallet.
- 5-day epochs: Every epoch, stake pools distribute proportional rewards.
- Approximate APY: 3-5% annually in ADA.
- No slashing: There is no risk of losing stake due to pool behavior.
Taxation of ADA staking rewards
Cardano staking rewards are taxed as income from capital in Spain.
Time of taxable event: When the rewards arrive in your wallet (after each epoch). With Cardano they can be the end of the second epoch after delegation.
Valuation: At the price of ADA at the time of receiving each reward.
Practical problem: With rewards every 5 days, in a year you accumulate ~73 fiscal events just by staking. Carrying this out manually is unfeasible.
Solutions to Register ADA Rewards
- Cardano Explorer (cardanoscan.io): Shows reward history per epoch.
- Pool.pm: Staking dashboard with history.
- Blockfrost APIs: To export bulk data.
- Automatic import: declaracrypto.es allows you to connect Cardano wallets and automatically calculate the value of each reward.
Annual calculation example
Configure that you have 10,000 ADA delegates and receive 400 ADA rewards during 2025.
If the average price of ADA upon receiving each reward is €0.40:
- Return on movable capital = 400 × 0.40 = €160
Those 400 ADA have an acquisition cost of €160 (to calculate the profit when you sell them).
Staking ADA Sale
When you later sell the reward ADA:
- Acquisition cost: value upon receipt (€0.40/ADA in the example).
- Profit = (sale price - 0.40) × number of ADA.
Native projects on Cardano (tokens)
Cardano has dozens of projects with native tokens (MIN, SNEK, AGIX, etc.). Trading these tokens works the same as any other altcoin:
- Purchase/sale: capital gain or loss.
- Reception as airdrop or farming reward: return on movable capital.
NFTs on Cardano
The NFT market on Cardano (JPEG Store, etc.) is also active. Tax treatment identical to that of Ethereum NFTs:
- Purchase with ADA = transmission of ADA (taxable event).
- NFT sale = capital gain/loss.
