All your Spanish tax obligations. One provider. One fixed annual fee.

The non-resident tax maze: what you actually owe

Owning property in Spain as a non-resident is a pleasure in many respects — and a source of unexpected administrative complexity in others. The Spanish tax authority (Agencia Estatal de Administración Tributaria, AEAT) has progressively tightened enforcement of non-resident obligations over the past decade, and the combination of automated information exchange under the Common Reporting Standard (CRS) and the EU’s DAC directives means that undisclosed Spanish income and assets are increasingly easy to detect.

The main taxes a non-resident property owner needs to manage are:

IRNR (Impuesto sobre la Renta de No Residentes): The non-resident income tax, applied to Spanish-source income and to imputed income on vacant properties. Filed via Modelo 210, either quarterly (for rental income) or annually by 31 December (for imputed income on non-rented properties).

Patrimonio (Impuesto sobre el Patrimonio): Wealth tax on Spanish-sited assets. Applies to non-residents on Spanish assets above 700,000 euros per individual. Filed via Modelo 714, due May-June for the prior year.

Plusvalía municipal: The municipal land value increment tax, levied by the local council on every transfer of urban property. Calculated on the increase in the cadastral value of the land (not buildings) since the date of acquisition, applying a set of municipal coefficients. Payable by the seller on a sale; by the heir or donee on inheritance or gift.

Modelo 720/721: Informational declarations for Spanish residents with foreign assets over 50,000 euros. Not applicable to non-residents, but becomes relevant if a non-resident purchases additional Spanish property and spends enough time in Spain to inadvertently become a Spanish tax resident.

Capital gains (IRNR plusvalía estatal): Tax on the gain realised on selling a Spanish property. A 3% withholding is automatically applied by the buyer at the notary; any overpayment is reclaimed via Modelo 210.

Why a single provider matters

Each of these taxes has different deadlines, different filing forms, and different calculation methodologies. Many non-residents manage them through a patchwork of local advisers — a gestor in the town where the property is located, an accountant back home who handles the overseas income declaration, and no one paying attention to the interactions between them. This fragmented approach is a reliable source of errors, missed deadlines, and missed opportunities to reduce liability.

A single provider who manages all your Spanish tax obligations has a complete picture of your position. When you sell a property, BMC knows your original acquisition cost, the improvements you made, and the depreciation claimed in prior years — information that is essential for an accurate gain calculation but frequently unavailable when it is needed. When you receive a rental income increase, BMC assesses whether wealth tax thresholds are affected. When you restructure your UK or US portfolio, BMC models whether the Spanish treaty implications are considered.

What BMC’s annual package includes

The standard annual package covers:

• Fiscal representation with the AEAT (mandatory for non-EU residents including British nationals)
• Annual IRNR imputed income filing (Modelo 210) for vacant or owner-occupied properties
• Quarterly IRNR rental income filings (Modelo 210) if the property is rented out
• Annual wealth tax return (Modelo 714) if Spanish assets exceed the threshold
• AEAT correspondence management — all official letters and notices handled without requiring your personal intervention
• Annual tax position review call with your dedicated tax manager

Capital gains advisory and Modelo 720/721 declarations are available as add-ons priced per transaction or declaration.

Country-specific considerations

UK nationals post-Brexit: Since 1 January 2021, UK nationals are treated as non-EU third-country nationals for Spanish tax purposes. This means rental income is taxed at 24% on gross income (no expense deductions), fiscal representation is mandatory, and the 3% capital gains withholding applies on property sales. The UK-Spain DTA remains in force and prevents double taxation, but the procedural burden has increased compared to the pre-Brexit position. BMC is familiar with the mechanics of the UK-Spain treaty and the HMRC paperwork required to claim relief on Spanish tax paid.

US nationals: American citizens are subject to worldwide income taxation by the IRS regardless of where they live. Spanish tax paid on Spanish property income creates a US foreign tax credit, but the interaction between the two systems requires careful management. FBAR (FinCEN 114) reporting is required for Spanish bank accounts above 10,000 USD at any point in the year. FATCA rules mean Spanish banks routinely report US-connected account holders to the AEAT, which exchanges the information with the IRS. BMC coordinates with US tax counsel for clients who need integrated Spanish-US advice.

German, Dutch, and Nordic nationals: EU residents benefit from the 19% IRNR rate and the ability to deduct expenses from rental income. Wealth tax applies at the same thresholds as for other non-residents. Several Northern European countries have particularly active information exchange arrangements with Spain, meaning undisclosed Spanish income has a high probability of detection.

Pricing transparency

BMC prices annual tax packages on a fixed-fee basis with no hourly billing or unexpected invoices. Fees are agreed upfront and cover all standard filings for the year. We publish indicative pricing on request and tailor packages to your exact asset profile — a client with one residential property in Alicante paying no rent has a straightforward profile; a client with three rental properties in different regions and a Spanish bank account has a more complex one. In both cases, you know the cost at the start of the year.

The AEAT data exchange network: why undisclosed Spanish income is increasingly visible

Many non-residents who have historically underreported or not reported Spanish tax obligations assume that the risk of detection is low. That assumption is becoming increasingly incorrect. Spain participates in a comprehensive network of international tax information exchange that makes previously invisible income and assets visible to the AEAT:

Common Reporting Standard (CRS) / DAC2. Under the OECD’s CRS framework, financial institutions in over 100 jurisdictions automatically report account information — balances, income payments, and transactions — to their domestic tax authority, which then shares the data with the AEAT for Spanish-resident account holders. For non-residents, Spanish financial institutions (including banks where non-residents hold accounts in Spain) report to the AEAT and to the account holder’s home tax authority.

DAC6 mandatory disclosure. Cross-border arrangements that meet certain hallmarks — including arrangements that circumvent automatic information exchange — must be reported to the AEAT by intermediaries (advisors, banks) or the taxpayer. This further reduces the effectiveness of opacity structures.

Property sale data. Spanish notaries are legally required to report all property sale transactions to the AEAT within 30 days of completion. The AEAT therefore has a complete record of all property transfers in Spain — and where a non-resident sale occurs without a subsequent Modelo 210 gain return, the discrepancy is automatically flagged.

Rental income from digital platforms. Since 2023, Spanish regulations require Airbnb, Booking.com, and similar platforms to report to the AEAT all rental income paid to Spanish property owners. This has dramatically increased the AEAT’s visibility of short-term rental income that was previously undisclosed.

Non-residents who have outstanding unfiled Modelo 210 returns, undeclared rental income, or unreported property sales are strongly advised to make a voluntary disclosure. The AEAT’s voluntary disclosure provisions (declaracion extemporanea sin requerimiento previo) apply reduced surcharges — starting at 1% for declarations filed within 3 months of the original deadline and rising to 15% for declarations more than 12 months late — that are substantially lower than the penalty regime triggered by a formal AEAT notice. BMC manages voluntary disclosure processes for non-residents across all outstanding obligation types.

Inheritance and gift tax for non-residents: post-ECJ ruling

Prior to a series of European Court of Justice rulings (C-127/12 and subsequent cases), non-EU residents inheriting Spanish assets were subject to the national ISD scale, without access to the more favourable autonomous community rules that applied to EU residents. This created materially worse outcomes for UK, US, and other non-EU nationals.

Following the ECJ rulings and their implementation in Spanish law, non-EU residents can now apply the autonomous community ISD rules of the community where the largest value of Spanish assets is located. In practice, this means a British national inheriting a property in Andalucía can apply Andalucía’s 99% ISD rebate for direct-line heirs — the same favourable treatment that applies to Andalucía-resident heirs. This change is significant and has not been widely communicated to non-residents and their advisors.

BMC manages the full inheritance process for non-residents: identifying the applicable autonomous community rules, preparing the ISD declaration using the most favourable legal basis, and coordinating with the property registry and notary for the transfer of title to heirs or beneficiaries. We also advise on pre-death gifting strategies — donations of Spanish property to children during the owner’s lifetime — where the autonomous community gift tax rules are even more favourable than the inheritance tax rules.

Frequently missed obligations: a checklist for non-resident property owners

Experience with thousands of non-resident client onboardings shows that the same obligations are consistently missed. This checklist covers the obligations that new BMC clients most frequently discover for the first time:

Annual imputed IRNR on vacant property. The most commonly missed obligation. Any non-resident who owns a Spanish property that is not rented out must file an annual Modelo 210 for deemed rental income: 1.1% of cadastral value (for properties with cadastral values revised after 1 January 1994) or 2% (for older cadastral values) is the deemed income, taxed at 19% (EU residents) or 24% (non-EU). For a property with a cadastral value of €200,000, this generates approximately €418 in annual tax — small in absolute terms, but with significant penalties and interest for non-filing accumulated over multiple years.

IBI (Impuesto sobre Bienes Inmuebles). The local council property tax, charged annually by the municipality. Non-residents frequently do not receive IBI bills at their home address and allow the amounts to accumulate in arrears. BMC advises on direct debit setup or annual review of IBI status to prevent enforcement proceedings against the property.

Community of owners contributions. Not a tax but legally required: membership of the comunidad de propietarios for any property in a development with shared areas (urbanisations, apartment blocks). Failure to pay community fees can result in the community obtaining a mortgage charge over the property.

Plusvalía municipal on sale. When selling, the plusvalía municipal (IIVTNU) is payable to the municipality within 30 days of the sale date. It is calculated on the increase in the land component of the cadastral value since acquisition, using municipal coefficients. Following the 2021 Constitutional Court ruling, the tax is not payable if there has been no actual increase in land value — but the seller must file a declaration and request the zero assessment, not simply omit to pay.

For each of these obligations, BMC provides either direct management or advice on the correct procedural approach, ensuring that non-resident property ownership remains fully compliant at all times.
