Solana: ecosystem, staking and taxation in Spain

Solana has established itself as one of the most active blockchains, with its own and growing DeFi, NFT and memecoins ecosystem. For Spanish investors, the tax treatment of SOL and its derivatives follows the same logic as other cryptocurrencies.

SOL as an investment asset

Basic operations with SOL (purchase, sale, swap) are taxed the same as Bitcoin or Ethereum:

• Equity gain/loss on the savings basis.
• FIFO method required.
• The taxable event is consolidated at the time of each transmission.

Important specificity: Solana has very low transaction fees (fractions of a cent), making high-frequency trading easy. With many trades, the FIFO calculation can become very complex, although the tax treatment is identical to any other crypto.

SOL Staking: how it is taxed

Solana uses Proof of History + Proof of Stake. To validate, users can:

1. Direct staking with a (native) validator.
2. Liquid staking through protocols such as Marinade Finance (mSOL) or Jito (JitoSOL).

Native staking

Native staking rewards on Solana automatically accumulate in the stake account. Technically, there is no explicit "cash out" until you destake and withdraw funds.

The most prudent tax criterion: declare the accumulated rewards as return on capital at the end of each year, valued at the price of SOL as of December 31.

Liquid Staking (mSOL, JitoSOL)

• You deposit SOL → you receive mSOL. This exchange can be considered transmission.
• mSOL increases in value against SOL over time (accumulates rewards internally).
• When withdrawing (mSOL → SOL), the profit is the difference in value.

NFTs on Solana

Solana's NFT ecosystem (Magic Eden, Tensor) is very active. The tax treatment is identical to that of Ethereum NFTs:

• Purchase with SOL → profit/loss for the transmitted SOL.
• NFT sale → capital gain/loss.
• Royalties → return on capital.

Memecoins on Solana (BONK, WIF, POPCAT, etc.)

Solana's memecoin trading has generated extreme returns (and equal losses). Fiscally there is no difference: each sale or swap is a taxable event.

With the high transaction volume typical of memecoins, registration is essential. declaracrypto.es can import the history of the Solana blockchain automatically.

Jupiter and DEX aggregators

Jupiter is the main swap aggregator on Solana. Each swap executed through Jupiter is a taxable transfer. Even if you use multiple routes internally, the end result (what you give and what you receive) is what determines the taxable event.

Operations log in Solana

Unlike Ethereum, Solana does not have as robust an explorer for exporting histories in CSV format. Recommended options:

• Solana Explorer + RPC APIs to export.
• Helius API for complete histories.
• Direct import through wallet connect on specialized platforms.
