Crypto Tax Reporting in Spain: When to Declare Crypto

You must declare when you carry out transactions that generate gains or losses (selling, swapping or paying with crypto) and when you earn income (staking, lending, airdrops). Buying and holding, on its own, is not taxed.

There may also be reporting and wealth tax obligations: Form 721 if you hold more than €50,000 in crypto abroad, and wealth tax if you exceed the tax-free threshold in your autonomous community.

If there is no disposal (sale, swap or payment), you normally do not declare gains or losses under IRPF. Buying crypto and holding it is not a taxable event.

But you may still have to file if you earn income, if your crypto abroad exceeds €50,000 (Form 721) or if you exceed the wealth tax threshold. It is worth analyzing custody and location before assuming that “it doesn’t apply”.

The most common: selling for euros, crypto-to-crypto swaps, paying for goods or services with crypto and receiving income (staking, lending interest or airdrops). If there is a transaction, you almost always have to calculate the result and support it.

Yes. The Spanish Tax Agency treats an exchange between cryptocurrencies as a swap that generates a capital gain or loss, even if you never convert to euros. When you swap BTC for ETH, for example, for tax purposes you are selling BTC and buying ETH: you must calculate the difference based on the euro market value of each token at that moment.

It is a key distinction that affects your tax bill. Staking and lending are treated as income from movable capital and taxed in the savings base. Airdrops, on the other hand, are usually treated as a capital gain not arising from a disposal and go into the general base (higher rates). Confusing them is one of the errors the Tax Agency reviews most closely.

To avoid mistakes: full exports from all exchanges, a list of wallets, on-chain movements, fees, purchase and sale receipts, and an annual summary by asset and transaction. With complete data, the calculation is solid and the return can be defended if a request for information arrives.

It is an information return on virtual currencies held abroad. It is mandatory if, at December 31, your combined balance on platforms outside Spain exceeds €50,000. It is filed between January 1 and March 31 of the following year. Crypto in self-custody (your own keys) does not count, unless it is linked to a foreign provider. We cover it in detail in Form 721.

It can lead to requests for information, regularizations, late-payment interest and penalties of 50% to 150% of the tax due on undeclared gains, plus the specific Form 721 fine. And with DAC8 and Forms 172/173, the AEAT already cross-checks data with exchanges. Correcting late is usually more expensive than declaring correctly from the start.

Yes. We analyze your historical activity, rebuild the calculation lot by lot and assess the most suitable route (supplementary returns or corrections) with supporting documents. We handle this together with Tax Agency audits of crypto. The sooner the evidence is in order, the less friction the process creates.

It depends on the number of exchanges and wallets, the volume of transactions and the years to be reviewed. The key factors are the time needed to consolidate the data and the quality of the starting data. After a quick review of your activity, we give you a tailored quote.

FIFO (First In, First Out) means that, when you sell, the units you bought first are deemed to be disposed of first. The AEAT requires it to calculate the gain: disposal value − FIFO acquisition value − fees. Applying it correctly lot by lot is essential when you have bought the same asset at different times and prices.

Inheritances and gifts of crypto are subject to inheritance and gift tax (Impuesto sobre Sucesiones y Donaciones), managed by each autonomous community. In addition, on a gift, the donor may realize a capital gain under IRPF if the value exceeds the acquisition value. We cover this in crypto inheritance.

They are information returns filed by exchanges registered in Spain: Form 172 reports balances at December 31 and Form 173 reports transactions. You do not file them, but they are one way the Tax Agency already knows about your activity in Spain. More detail in Form 172.

The savings base (gains from sales or swaps, staking, lending) is taxed at progressive rates starting at 19%. The general base (airdrops, habitual mining, payments in crypto for services) is added to the rest of your income and can reach much higher marginal rates. That is why classifying each item of income correctly changes the result.

Yes, within limits. Capital losses are first offset against gains of the same kind in the same tax year; any remaining negative balance can be offset up to 25% against income from movable capital. Anything not offset is carried forward over the following four tax years. That is why you should always declare losses.

It only counts as a deductible capital loss if strict requirements under the IRPF Regulations are met (a police report, insolvency proceedings or a proven uncollectible debt). In practice the AEAT is very restrictive, so each case should be analyzed with the documents in hand before including it.

The taxation described here applies to tax residents in Spain. Non-residents are subject to non-resident income tax (Impuesto sobre la Renta de No Residentes) and to double tax treaties, with different rules. Correctly determining tax residence is the first step and should be analyzed case by case.
