Spain's Tax Authority Steps Up Non-Resident Property Checks: What the 2026 Control Plan Means for Costa Blanca Owners
Spain's tax agency has named non-resident property owners as an explicit enforcement priority for 2026 — and the tools at its disposal are sharper than ever. If you own a home on the Costa Blanca and live outside Spain, here is exactly what the Agencia Tributaria is looking at, and why getting your filings in order today is the sensible move.
What Is the 2026 Annual Tax Control Plan?
Every year Spain's Agencia Tributaria (AEAT) publishes its Plan Anual de Control Tributario y Aduanero — an official document setting out the sectors, taxpayer groups and tax heads it will focus on during the year. The 2026 edition was approved by BOE-A-2026-5843, a resolution of 11 March 2026 published in the Official State Gazette (Boletín Oficial del Estado, BOE) on 12 March 2026.
Non-residents with income or property in Spain are named explicitly in the 2026 Plan as an enforcement priority. The AEAT's own explanation is matter-of-fact: "non-resident persons who own assets in Spain, directly or indirectly through entity shareholdings, represent an increasingly numerous group." International buyers have driven that growth — Alicante province alone accounts for nearly 43% of all foreign property purchases across Spain — and the tax register is catching up.
The Three Tax Areas Under Active Scrutiny
1 — IRNR: rental income and capital gains
The Impuesto sobre la Renta de No Residentes (IRNR) is the non-resident income tax, filed via Modelo 210. The 2026 Control Plan highlights two specific IRNR areas:
Rental income imputation. Non-residents who leave a property empty or use it solely for personal holidays must declare a deemed rental income every year (imputación de rentas inmobiliarias) — even without a single paying tenant. HAC/623/2026 (June 2026) updated the filing deadlines and consolidated quarterly returns into a single annual declaration from 1 April. The 2026 Control Plan tasks inspectors with cross-checking these filings against property-registry data.
Capital gains on property sales. When a non-resident sells a Spanish property, the buyer withholds 3% of the purchase price and pays it to AEAT via Modelo 211 as an advance tax payment. A separate IRNR return must then be filed to calculate the actual gain and claim any refund of excess withholding. The 2026 Plan specifically directs inspectors to verify that these returns have been filed and that the gain has been correctly calculated.
2 — Wealth Tax
Non-residents holding Spanish assets above certain thresholds are liable for Impuesto sobre el Patrimonio (Wealth Tax) under obligación real rules — Spain taxes the value of assets located within its borders regardless of where the owner is resident. The 2026 Control Plan includes Wealth Tax within its non-resident inspection programme. EU/EEA residents may benefit from regional allowances; non-EU owners — including British nationals since Brexit — should take specific advice on their exposure. In the Valencian Community, a €500,000 individual exemption applied from the 2024 tax year.
3 — Corporate and entity structures
Investors holding Spanish property through a company — a Spanish SL, a foreign holding vehicle, or shares in a property-owning entity — are explicitly named in the 2026 Plan under the heading SOCIMI y no residentes. AEAT will scrutinise whether capital gains and rental income flowing through these structures have been correctly declared under IRNR rules. Owning through a company does not eliminate Spanish tax liability; it changes which form of IRNR applies and how income is calculated.
How AEAT Is Now Detecting Filing Gaps
The most significant change in the 2026 Plan is not a new tax — it is the sophistication of detection. The agency has moved from reactive audits to continuous, automated data-matching, drawing on:
- Property registry data cross-referenced against IRNR filings and Wealth Tax returns
- Rental platforms (DAC7): EU Directive 2021/514 (DAC7), fully operational from January 2024, requires Airbnb, Booking.com, Vrbo and similar platforms to report users' income directly to the tax authority
- Bank and payment data: AEAT now has monthly access to bank-account ownership information for cross-referencing
- International exchange (CRS / DAC2): under the Common Reporting Standard, foreign bank accounts and investment income are automatically reported to Spanish authorities by overseas financial institutions
A rental that went unreported in prior years is now far more likely to surface in an automated risk-selection run. The window for voluntary regularisation — before AEAT acts first — is narrowing.
A Practical Checklist for Costa Blanca Owners
If your filings are up to date, the 2026 Control Plan simply confirms that the system is working as intended. For owners who have not yet regularised their position, the table below is a useful starting point.
| Area | What to check |
|---|---|
| Modelo 210 — annual property filings | All years from acquisition filed, including years of personal use only |
| Rental income via Airbnb / Booking | Earnings declared match what the platform reported to AEAT |
| Property sold (past five years) | Final IRNR return filed; Modelo 211 excess correctly claimed or offset |
| Wealth Tax | Spanish assets assessed against threshold; Valencian €500,000 exemption applied |
| Company ownership | IRNR filings reflect actual rental income and gains within the structure |
An independent asesor fiscal or gestor registered in Spain can review your entire position in a single session. Elia Living's network of trusted English-speaking advisers in Jávea can make introductions.
The Bigger Picture
Spain's enforcement modernisation is part of a Europe-wide trend: DAC7, the emerging DAC8 framework for crypto assets, and the Common Reporting Standard together mean that AEAT today has access to information that would previously have required years of investigation. For diligent owners, that is a level playing field. For those who have been meaning to sort out their filings, acting proactively — before a query arrives — is both simpler and significantly cheaper.
The Costa Blanca remains an outstanding place to own property. The tax obligations for non-residents are clear once understood, and the English-speaking network of tax advisers, gestores and lawyers in Jávea and across the Costa Blanca North is deep and experienced. The 2026 Control Plan is not a reason for alarm — it is a useful prompt to check that your position is exactly as it should be.
Frequently Asked Questions
Do I have to file a Spanish tax return if I just use my Costa Blanca villa as a holiday home and never rent it out? Yes. Non-resident owners must file Modelo 210 every year for the imputación de rentas inmobiliarias — a deemed rental income based on the cadastral value of the property. The tax is modest, but the obligation exists regardless of whether the property earns a euro in rent. HAC/623/2026 (effective 24 June 2026) updated the filing deadlines.
What taxes apply when I sell my Costa Blanca property as a non-resident? The buyer retains 3% of the sale price and pays it to AEAT via Modelo 211 as an advance IRNR payment. You must then file a separate IRNR return calculating the actual capital gain. If the 3% exceeds your liability, you can claim a refund. The 2026 Control Plan specifically targets these returns for inspection.
I own my Spanish property through a limited company. Does the corporate structure protect me from IRNR? No. AEAT specifically names property-holding corporate structures in the 2026 Control Plan. The tax liability exists whether you own directly or through an entity; the applicable IRNR form and calculation method differ. Specialist advice is strongly recommended for any company structure.
What is DAC7 and how does it affect my Airbnb rental income? DAC7 is an EU directive requiring digital rental platforms — Airbnb, Booking.com, Vrbo and others — to report each user's annual income directly to national tax authorities. AEAT receives this data and will cross-check it against your Modelo 210 filings. Any gap between what the platform reported and what you declared is a straightforward trigger for a query.
Am I subject to Spanish Wealth Tax as a British owner since Brexit? Yes. Non-EU owners are taxed on their Spanish assets under obligación real rules. In the Valencian Community, a €500,000 per-person exemption applied from the 2024 tax year, but assets above this threshold are taxable. The 2026 Control Plan includes Wealth Tax explicitly within its non-resident inspection programme.
