How to Sell Your Property in Spain and Get Paid in Crypto

Why Sellers in Spain Are Being Offered Crypto

Foreign buyers accounted for 15.98% of all home purchases registered in Spain in the second quarter of 2026, according to the Colegio de Registradores, and a growing number of them hold a significant part of their wealth in digital assets. For sellers, this creates a new question: what happens legally and fiscally if the buyer offers to pay in crypto, or if the seller wants to be paid in crypto? Vicox Legal advises on crypto real estate transactions in Spain and Portugal for both buyers and sellers, and the seller’s side raises issues that most guides ignore.

The context in 2026 is more structured than ever. Spain’s MiCA transitional period for crypto-asset service providers ended in July 2026, so only authorised providers can convert or hold crypto for Spanish clients. DAC8 has applied across the EU since 1 January 2026, so crypto transactions through EU providers are reported to tax authorities. And Spanish notaries continue to apply strict rules on identifying the means of payment in every property deed.

This guide explains how a seller can receive crypto for a Spanish property, the difference between being paid in euros funded by crypto and being paid directly in crypto, the AML file the notary will expect, the taxes that fall on the seller, including the 3% withholding for non-residents and the municipal capital gains tax, and how to choose between bitcoin, ether and stablecoins.

Legal and Regulatory Framework in Spain

Under Spanish law, the sale of a property for crypto is governed by the general rules on the transfer of real estate, the anti-money laundering regime, the crypto-asset regulation and the tax rules that apply to the seller. Six layers interact.

Civil law: sale or exchange

The Spanish Civil Code defines a sale (compraventa, Article 1445) as a contract in which one party delivers a thing in exchange for a price in money or a sign that represents it. Crypto-assets are not legal tender in Spain. When the buyer delivers crypto rather than euros, the contract is generally characterised as an exchange (permuta, Article 1538), in which each party delivers one asset in return for another. The classification determines how the seller’s gain is calculated and how the deed is drafted.

Anti-money laundering: Ley 10/2010 and SEPBLAC

Ley 10/2010 designates notaries, registrars, real estate agents, banks and crypto-asset service providers as obligated subjects. Each must identify both parties, establish the beneficial owner and understand the origin of the funds. SEPBLAC is the Spanish financial intelligence unit, and notaries channel their AML function through the Órgano Centralizado de Prevención of the Consejo General del Notariado. The seller is not a passive party: the notary identifies the seller and will ask where the crypto received is going.

Notarial and registry rules

Spanish notaries must identify the means of payment in every deed of transfer, under the Notarial Law and the Notarial Regulation. Article 254 of the Ley Hipotecaria prevents registration where the means of payment have not been identified. For a crypto payment, this means recording the asset, the amount, the wallet addresses and the transaction identifiers.

MiCA and the Transfer of Funds Regulation

Regulation (EU) 2023/1114 (MiCA) governs the providers through which crypto is converted or held, and the stablecoins that can be offered in the EU. Regulation (EU) 2023/1113 applies the travel rule, so transfers between providers carry originator and beneficiary information. A seller who plans to convert crypto received into euros will need an authorised provider and a clean transfer history.

Taxation of the seller

A resident seller’s gain is taxed under the Personal Income Tax Law (Ley 35/2006). A non-resident seller is taxed under the Non-Resident Income Tax Law (Real Decreto Legislativo 5/2004), which also imposes the 3% withholding on the buyer. The municipal tax on the increase in urban land value (IIVTNU, known as plusvalía municipal) is governed by Real Decreto Legislativo 2/2004 as amended by Real Decreto-ley 26/2021.

DAC8

Directive (EU) 2023/2226 (DAC8) requires crypto-asset service providers to report client transactions to tax authorities, with data collection from 1 January 2026. A seller who receives crypto and later converts it through an EU provider should expect the conversion to be reported.

Two Ways to Get Paid in Crypto for a Spanish Property

The legal structure of a crypto-funded sale follows one of two routes: the buyer converts crypto to euros and pays the seller in euros, or the buyer delivers crypto directly to the seller. The choice determines who bears the conversion, the volatility and the tax consequences.

Route 1: euro settlement funded by crypto

In the most common structure, the buyer sells crypto through a MiCA-authorised provider and pays the price by bank transfer. For the seller, the sale is a standard euro transaction: the seller receives euros, the deed records a bank transfer and the seller’s tax position is identical to any other sale. The crypto element sits entirely in the buyer’s AML file. This is the structure Vicox Legal typically coordinates for clients who buy real estate with crypto, and the simplest option for a seller who simply wants to accept a crypto-funded buyer.

Route 2: direct payment in crypto

In a direct crypto payment, the buyer transfers crypto-assets to a wallet controlled by the seller, and the deed records that transfer as the consideration. The contract is generally characterised as an exchange. The seller acquires crypto at the moment of the deed, with an acquisition value equal to its market value at that date, and takes on all subsequent price movements. This structure suits sellers who want to hold crypto, such as investors reallocating property wealth into digital assets, or sellers who will reinvest in crypto in any case.

Hybrid structures

Sellers frequently combine both routes: part of the price in euros, to cancel an existing mortgage, cover the non-resident withholding and pay taxes, and the rest in crypto. Hybrid structures are workable but must be drafted precisely, so that the notary can identify each payment and the tax base is correctly calculated.

Step-by-Step Transaction Flow

The process involves seven stages, from verifying the buyer’s crypto to registering the new owner. The same sequence applies to both routes, with differences noted in each step.

1. Verification of the buyer’s wallet and origin of funds — Before accepting an offer, the seller’s adviser asks for evidence of how the buyer acquired the crypto: exchange statements, on-chain history and tax filings. A buyer who cannot document the origin of funds is likely to be stopped by the notary, leaving the seller with a failed sale and lost time.
2. AML/KYC validation of both parties — The notary identifies buyer and seller, their beneficial owners and politically exposed person status. In a direct crypto payment, the seller’s own wallet and its intended use are also reviewed, and the seller’s bank will apply its own checks when the crypto is later converted.
3. Preparation of legal documentation — The seller gathers title documents, the latest IBI receipt, the energy certificate, the community certificate of no debts and, where required, the certificate of occupancy. Counsel drafts the arras contract, specifying the payment route, the crypto asset and amount or the euro price, the valuation date and who bears volatility until completion.
4. Crypto-to-fiat conversion or crypto transfer — In the euro route, the buyer converts crypto through a MiCA-authorised provider and transfers euros to a notarial or bank-controlled payment flow. In the direct route, the parties agree the wallet addresses and execute the transfer at or immediately before signing, with confirmations verified before the deed is authorised.
5. Notarial execution (escritura pública) — Buyer and seller sign the deed before a Spanish notary, who verifies identity, beneficial ownership and means of payment, and records the bank transfers or the on-chain transaction identifiers. Any mortgage is cancelled at completion with euros paid directly to the lender.
6. Tax settlement (ITP or VAT + AJD, withholding and plusvalía) — The buyer pays transfer tax, or VAT plus stamp duty on a new build. If the seller is non-resident, the buyer withholds 3% of the price and pays it to the tax authority using form 211 within one month. The municipal capital gains tax is declared to the town hall within the applicable deadline.
7. Inscription in the Land Registry — The deed is presented to the Registro de la Propiedad, which records the buyer as owner. For the seller, registration completes the transfer and ends liability for future property taxes.

AML and KYC Compliance for Sellers Receiving Crypto

AML compliance in a crypto-funded sale is defined by a principle that sellers often overlook: a seller who accepts tainted funds faces the consequences of a failed or blocked transaction, and in a direct crypto payment, may end up holding assets that no regulated provider will convert.

Who carries the obligations

The notary, the real estate agent, the banks involved and any crypto-asset provider are obligated subjects under Ley 10/2010. Each must apply customer due diligence, keep records for ten years and report suspicious transactions to SEPBLAC without delay. The seller is not an obligated subject but is identified by all of them, and a seller who knowingly accepts illicit funds can incur liability.

KYC versus AML for the seller

KYC (know your customer) refers to identifying the parties: identity, residence, beneficial ownership and politically exposed person status. AML (anti-money laundering) refers to the legitimacy of the money: the buyer’s source of funds and source of wealth, and, in a direct crypto payment, the destination of the crypto received. A seller should ask for the buyer’s origin-of-funds file before signing the arras, not on the day of the deed.

Red flags for sellers

Cash declarations and the S-1 form

The S-1 declaration applies to physical movements of cash and bearer instruments of €10,000 or more into or out of Spain. It is not relevant to crypto or bank transfers, but Spanish law also limits cash payments in transactions involving a professional to €1,000, so no part of the price should be settled in cash.

Risk of notarial refusal

A notary who cannot establish the origin of funds or the beneficial owner may decline to authorise the deed. For a seller, that means a failed sale after months of negotiation. Our guide to crypto-backed loans for property in Spain and our analysis of buying property in Portugal with crypto explain how compliant buyers structure their funds.

Tax Implications for the Seller

A sale for crypto produces the same Spanish taxes as any sale, with two additional elements: the valuation of the crypto in the seller’s gain calculation, and the future tax on the crypto if the seller is paid directly in it.

Capital gain on the property: resident sellers

A Spanish-resident seller pays personal income tax on the gain, calculated as the transfer value minus the acquisition value, each adjusted for the costs and taxes inherent to the operation. The gain is taxed in the savings base at rates from 19% to 30%. Exemptions may apply for the sale of a main home when the proceeds are reinvested in a new main home, or for sellers over 65 selling their main home.

Capital gain on the property: non-resident sellers

A non-resident seller pays non-resident income tax at 19% on the gain. The buyer must withhold 3% of the agreed price and pay it to the tax authority using form 211 within one month of the sale. The seller then files form 210 to declare the gain, offsetting the 3% withheld and paying any difference, or claiming a refund if the withholding exceeds the tax due.

How the gain is calculated when paid in crypto

In an exchange, Spanish personal income tax law calculates the gain as the difference between the acquisition value of the property delivered and the higher of the market value of the property delivered or the market value of the crypto received. The crypto then enters the seller’s wealth with that value as its acquisition cost. If the seller later sells the crypto, a new gain or loss arises based on its value at that time. Because crypto and property values can diverge, the valuation at the date of the deed should be documented with a reliable market price source.

Municipal capital gains tax (plusvalía municipal)

The IIVTNU taxes the increase in value of urban land between acquisition and sale and is paid by the seller in a sale. Since Real Decreto-ley 26/2021, the taxpayer can choose between an objective method based on cadastral land value and coefficients, or the real gain, and no tax is due if there is no real increase in value. When the seller is a non-resident individual, the buyer is the substitute taxpayer and in practice retains the amount from the price.

VAT for developers

Where the seller is a developer selling a new build, the sale is subject to VAT. If the consideration is crypto, the taxable base is the market value of the crypto received, and the invoice must be issued in euros.

Holding crypto after the sale

A Spanish-resident seller who receives crypto and holds it with a foreign custodian must file Modelo 721 if the value exceeds €50,000 at year end. Holdings with Spanish providers are reported by the providers themselves. Under DAC8, any later conversion through an EU provider will be reported to tax authorities.

Risk Mitigation and Due Diligence

Risk for a seller paid in crypto is defined by three exposures: the price risk of the crypto, the legitimacy of the buyer’s funds and the euro obligations that still have to be met at completion.

Price risk between arras and completion

If the arras fixes the price in crypto, the seller bears the risk that its euro value falls before completion. If it fixes the price in euros but payment is in crypto, the parties must agree the valuation source and timing. A common solution is a euro price with a crypto amount calculated at a defined reference rate shortly before signing, with an adjustment mechanism if the market moves beyond a threshold.

Price risk after completion

In a direct crypto payment, the seller holds a volatile asset from the moment of the deed, while the tax on the property gain is calculated on the value at that date. A sharp fall after signing does not reduce the tax due on the property sale. Sellers who need certainty should convert immediately or choose euro settlement.

Risk of notarial refusal

Funds from unidentified sources, unauthorised platforms or wallets with poor history can lead the notary to refuse the deed. The arras should allocate the consequences of a refusal caused by the buyer’s funds, including retention of the deposit.

Existing mortgage and charges

A mortgaged property cannot be sold free of charges unless the loan is repaid at completion, and lenders accept only euros. The payment schedule must include a euro amount sufficient to cancel the mortgage, along with the seller’s other debts on the property.

Unregulated stablecoins and mixed structures

Stablecoins that are not authorised in the EU may be difficult to convert through MiCA-compliant providers. Mixed structures, combining crypto, euros and third-party funds, multiply the documentation required. Each payment must be traceable independently.

Pre-sale legal advice

Before accepting an offer in crypto, the seller should obtain advice on the legal classification of the contract, the tax calculation, the withholding and the mechanics of payment. Most failed crypto-funded sales fail on documentation, not on price.

Bitcoin, Ether or Stablecoins: What Should a Seller Accept?

The choice of crypto-asset determines the seller’s volatility exposure and the ease of converting it later. The table below summarises the main options from the seller’s perspective.

For most sellers, euro settlement or a MiCA-authorised euro stablecoin offers the best balance between accepting crypto-funded buyers and avoiding market risk. Bitcoin or ether payment makes sense when the seller deliberately wants to hold those assets.

Advantages for International Sellers

Accepting crypto-funded buyers gives sellers in Spain specific advantages, provided the transaction is structured correctly.

• A wider pool of buyers. Crypto holders are a growing segment of international demand, particularly for high-end coastal and urban property.
• Speed. A buyer with documented crypto and an authorised conversion provider can complete without waiting for mortgage approval.
• Portfolio reallocation. Sellers who want to move property wealth into digital assets can do so in a single transaction through a direct payment.
• Cross-border convenience. Non-resident sellers can receive value without depending on cross-border bank transfers, while still meeting Spanish tax obligations.
• Legal certainty. The deed, the notary’s verification and registration protect the seller in the same way as in a euro sale.

Pre-Sale Checklist for Sellers Accepting Crypto in Spain

• Decide whether you will accept euros funded by crypto, direct crypto payment or a hybrid.
• Request the buyer’s origin-of-funds file before signing the arras.
• If paid in crypto, choose the asset and confirm that a MiCA-authorised provider can convert it for you.
• Set up a wallet in your own name, or an account with an authorised provider, to receive the crypto.
• Agree in the arras the price currency, valuation source, valuation time and who bears volatility.
• Calculate the euro amount needed at completion to cancel any mortgage and settle debts on the property.
• If you are non-resident, factor in the 3% withholding and prepare form 210.
• Estimate your capital gain and plusvalía municipal using the valuation that will apply on the deed date.
• Gather title, IBI receipt, energy certificate, community debt certificate and other required documents.
• Share the payment structure and wallet details with the notary before the signing date.
• Document the market price of the crypto at the time of the deed for your tax records.
• Plan when and how you will convert or hold the crypto received, and the reporting that follows.
