How to declare cryptocurrency staking income in Spain

Staking turns locked-up crypto into periodic returns. In Spain, the tax authorities (Hacienda) classify those rewards (as a general rule) as income from movable capital (rendimientos del capital mobiliario) in the savings base (base del ahorro), valued in euros on the date of receipt; later, if you sell those tokens, you will be taxed on the capital gain/loss relative to the value already declared.

In addition, if you hold crypto with foreign exchanges and exceed certain thresholds, there is an information obligation under Form 721 (Modelo 721).

What is cryptocurrency staking?

Staking consists of locking crypto-assets on Proof of Stake networks (or delegating them to a validator) in order to validate transactions and receive rewards in tokens. The Directorate-General for Taxes (Dirección General de Tributos, DGT) distinguishes between direct staking (you act as a validator with your own infrastructure) and delegated staking or staking “as an investment” (you lock your assets and share the reward with a third party); in both cases, the rewards are treated (as a general rule) as income from movable capital.

Quick differences from mining and holding

• Mining (PoW): it is usually analysed as an activity carried out with material resources; different treatment.
• Holding: keeping crypto without receiving anything does not in itself give rise to taxation, unless there is income (e.g. staking, lending).

Why is staking so often a tax headache?

• Classification and accrual: The DGT has set its position (V1766-22): staking = movable capital; the rewards must be valued in euros when they are received. Then, if you sell those tokens, the cost will be that value already included.
• Documentation and traceability: Without statements, txid, source/destination wallets and the euro exchange rate by date, it is difficult to justify amounts and bases.
• Information obligations: If you exceed thresholds with crypto held outside Spain, Form 721 comes into play (an information return, no tax is payable).

Possible consequences of not declaring staking properly

• Fines and surcharges for omitting income: Staking rewards are income and must be included in your Personal Income Tax (Impuesto sobre la Renta de las Personas Físicas, IRPF) return; omitting them can lead to financial penalties and late-payment interest.
• Requests for information and inspections: The Spanish Tax Agency (Agencia Estatal de Administración Tributaria, AEAT) may ask for traceability: wallets, txid, euro valuations and proof of receipt.
• Impact on your “tax record”: Previous incidents make instalment or deferral arrangements harder to obtain and increase the risk of further audits.

How to declare staking income step by step

1) Identify the type of income

As a general rule, staking rewards are treated as income from movable capital (savings base). If you act as a validator with organised resources and on a regular basis, check whether your case qualifies as an economic activity.

2) Determine which base it goes into

Staking is included in the IRPF savings base (progressive bands). If you also later sell those same tokens, that sale will generate a capital gain or loss, taking as the cost the euro value you already declared when you received them.

3) Declare it on Form 100

Report the total annual amount in euros of the rewards received in the income from movable capital section of the savings base. You do not need to convert the crypto-assets in your wallet into euros; what is included is the euro value of what you received on the date of receipt.

4) Practical example (summary)

• January: you receive 10 units of token X as staking. On that day they are worth €5 each → €50 of income from movable capital.
• March: you receive 4 units (price €6) → €24.
• December: you sell the 14 units for €80 in total. For the gain/loss, the cost is the €74 already declared as income (50 + 24). Result of the sale: €80 − €74 = €6 of capital gain.

5) Check whether you must file information returns.

If you hold crypto with foreign providers and exceed the thresholds at 31 December, there may be an annual information obligation (no tax is payable) on holdings abroad. Review your situation.

If you find all these steps complicated, you can always contact a specialist advisory firm.

Additional tax forms you might need

Form 714 – Wealth Tax

Assess whether your net wealth (including cryptocurrencies at market value at 31/12) exceeds the exempt minimums set by your autonomous community (comunidad autónoma) or, even if no tax is payable, whether there is an obligation to file because you exceed certain thresholds. Where applicable, it is filed annually, together with the income tax return.

Form 721 – Virtual currencies abroad

An information return for crypto holdings held outside Spain when thresholds are exceeded at 31 December. It may also be required in subsequent years if there are significant changes (significant additions/disposals or substantial increases). The ordinary deadline is the first quarter of the following year.

Forms 172 and 173 – Transactions and balances in crypto-assets

They are information returns filed by providers (exchanges, custodians and certain intermediaries established in Spain). The user does not file them, but should be aware that these reports can be cross-checked against their IRPF return: it is advisable for your records to match what your providers declare.

How to calculate the value of rewards correctly

Valuation method (practical rule and legal basis). Staking rewards are income in kind and must be valued in euros at the exact moment of receipt at their normal market value; that is the amount you will include in the savings base.

Afterwards, if you sell those same tokens, the gain or loss will be calculated against that value already declared as the cost. Administrative doctrine on staking also confirms its classification as movable capital (unless there is an activity carried out with organised resources).

How to estimate the value accurately (step by step)

1. Exact timestamp: record the date and time of each receipt (using a consistent time zone throughout the year).
2. Reference price: take the market spot price at that instant (if there are several markets, use that of the platform where you receive the rewards or a reasonable and consistent average price).
3. Conversion to euros: convert the value of the token into EUR on that same date/time (if the reward arrives in another currency or crypto pair, document the double conversion: token→USD/USDT→EUR).
4. Fees: record network or platform fees associated with the receipt (not with future sales) and keep them as an expense linked to that income where applicable.
5. Annual consistency: always apply the same source and method of conversion; record any change of methodology in an internal control note.

Operational criteria for special cases

• Vesting or periodic unlocks: accrual takes place when the tokens become available to you (not when they are announced). Value and record each delivery.
• Illiquid tokens or tokens with a high spread: use an average of prices over the interval close to receipt and document the source; avoid anomalous prices from isolated candles.
• Rewards in liquid staking: treat them as income from the token received; if you later redeem them for the underlying asset, calculate the capital gain or loss with a cost equal to the value already included on the date of receipt.
• Validators with their own resources: if there is regularity and organisation of resources, check whether there is an economic activity (accounting and specific obligations).

Minimum documentation you must keep (traceability)

• Rewards ledger: date/time, txid, source/destination wallets, token and value in EUR; identify the price source used.
• Evidence of price and exchange rate: screenshots/exports showing the spot price taken and the exchange rate to EUR.
• Annual reconciliation: total income per token and a table of subsequent sales in which the cost is the value already included as income.
  Well-organised documentation reduces the risk in tax audits and aligns your calculation with the applicable criteria for valuing income in kind.

Tools that make the process easier

If you carry out a large number of transactions, tax trackers and aggregators (or a well-designed spreadsheet) help you to import transactions, tag staking income, set the valuation rule and export an annual report with totals per token and justification of the cost for future sales. Carry out a manual review at year end to reconcile totals with your wallets/exchanges and with the accrual criterion applied.

Common mistakes to avoid when declaring staking

• Not declaring until you “cash out into euros”: Rewards are included when they are received, valued in euros on that same day, even if you do not convert or sell them.
• Using the wrong IRPF boxes: As a general rule, they are reported as income from movable capital in the savings base (not under economic activities unless you act as a validator with organised resources).
• Allocating to the wrong tax year: Accrual occurs on the date of receipt; without chronological control you will end up declaring late or in the wrong year.
• Mixing valuation criteria: Changing source or method mid-year breaks consistency. Choose one price source and one EUR conversion rule and keep them for the whole tax year.
• Forgetting the subsequent sale of tokens already declared: When you sell those rewards, use as the cost the euro value you reported on the day you received them; otherwise, you are taxed twice.
• Not keeping supporting evidence: Without txid, wallets, price screenshots, fees and reconciliations, your calculation is weak in the event of a tax audit.

Recommendations for complying properly with the tax authorities

• Keep records regularly: Maintain a rewards ledger with date/time, token, txid, source/destination wallets, value in EUR and fees. Add a monthly total to keep track of the running balance.
• Quarterly reconciliation: Reconcile your ledger with your wallet/exchange balances and record any differences (e.g. airdrops, bridges, fees).
• Methodology annex: Document in advance the price source, the reference time, the exchange rate to EUR and how you treat special cases (vesting, liquid staking, illiquidity).
• Review information obligations: If you hold crypto abroad and exceed thresholds at 31/12, prepare the corresponding information return; and assess whether your net wealth requires a wealth tax return.
• Validator or high regularity: If you operate with organised resources (node, infrastructure, third parties), check whether there is an economic activity and what formal obligations it entails.
• Update every tax season: Review the latest changes before filing: bands, boxes, deadlines and criteria.

Frequently asked questions about the taxation of staking

Is staking on a centralised exchange the same as on a decentralised one?

For Spanish tax purposes, the classification does not change: the reward is, as a general rule, income from movable capital that is included in the savings base and valued in euros on the date of receipt. The nature of the provider (CEX/DEX) does not alter accrual or the obligation to declare, although it does affect the traceability requirements (justifying txid, wallets and prices). This criterion is based on the DGT’s rulings on staking and on the IRPF manual for the savings base.

Can it be offset against losses on other crypto?

Yes, but following the rules on aggregation and offsetting: income from movable capital (such as staking) is offset first within its own block of the savings base and, if a negative balance still remains, against 25% of the positive balance of the other block (capital gains/losses) and vice versa, respecting the four-year time limit.

What happens if you receive staking rewards from a foreign exchange?

You must still declare it in your IRPF return as income from movable capital. In addition, if at 31 December the total virtual currencies held outside Spain exceed €50,000, there is an information obligation through Form 721 in the first quarter of the following year.
