I Received a «Requerimiento» from Hacienda: A Step-by-Step Guide for Non-Residents
If you’ve just opened a letter or email from the Spanish Tax Agency (Agencia Tributaria/Hacienda) with the word «requerimiento» (official tax request) prominently displayed, your heart rate has likely accelerated, panic is setting in, and you’re wondering: What is this? Why did I receive it? What happens if I ignore it? And most critically—how much time do I have to respond?
For non-resident property owners in Spain—UK buyers with vacation homes in Costa del Sol, German retirees with Mallorca apartments, French investors with Barcelona flats, US expats owning Madrid properties—a requerimiento from Hacienda represents one of the most urgent and potentially costly tax compliance crises you can face, because unlike casual reminders or informational notices, a requerimiento is a formal legal demand requiring you to provide documentation, clarify tax filings, or pay outstanding taxes within an extremely short deadline—typically 10 business days from the date of notification—and failure to respond triggers automatic penalties ranging from €150 to €600,000 (yes, six hundred thousand euros), potential asset seizures, enforcement orders (providencia de apremio) authorizing Hacienda to freeze bank accounts or garnish rental income, and in severe cases, criminal investigations for tax fraud if the amounts involved exceed €120,000.
The requerimiento you received likely stems from one of five common triggers: (1) failure to file Modelo 210 (non-resident income tax for rental income or imputed income from property ownership), (2) late or incorrect Modelo 210 filing (Hacienda detected errors in your declared rental income or property value), (3) failure to file Modelo 720 (declaration of foreign assets exceeding €50,000 if you’re a Spanish tax resident), (4) discrepancies between your tax filings and third-party data (banks, notaries, or rental platforms reported income Hacienda believes you didn’t declare), or (5) outstanding tax debt (unpaid taxes from previous years now escalating to enforcement stage).
This guide provides the emergency roadmap every non-resident needs RIGHT NOW: WHAT a requerimiento is (formal legal demand vs. casual correspondence), WHY you received it (the 5 most common triggers for non-residents), WHAT the deadline is (10 business days—calculated excluding weekends and Spanish public holidays, starting the day AFTER notification), HOW to respond step-by-step (document gathering, translation requirements, electronic submission via Hacienda portal or physical delivery), WHAT happens if you miss the deadline (automatic penalties starting at €150, escalating to €600,000 for serious infractions, plus asset seizure authority), HOW to request an extension (you can request up to 5 additional business days if you apply MORE THAN 3 DAYS before the original deadline expires), and WHEN you need professional help (if the requerimiento involves amounts exceeding €5,000, multiple tax years, or allegations of fraud, you MUST hire a Spanish tax lawyer immediately—attempting DIY responses in these situations often worsens your position and forfeits appeal rights).
Whether you’re a London accountant who’s never dealt with Spanish tax law, a Berlin engineer panicking because the requerimiento is entirely in Spanish and references obscure tax codes, a Paris consultant who thought your rental agent handled all tax filings, or a New York investor who assumed non-residents didn’t need to file annual returns, this guide ensures you understand the urgency, know exactly what steps to take TODAY, and—if the situation is beyond your expertise—connect with qualified Spanish tax professionals who can respond on your behalf before the 10-day deadline expires and penalties become irreversible.
IMMEDIATE ACTION REQUIRED: Understanding Your 10-Day Deadline
The Most Critical Information You Need RIGHT NOW
If you received a requerimiento from Hacienda, you have ONLY:
10 business days to respond (calculated from the day AFTER notification)
«Business days» means:
- Exclude: Saturdays, Sundays, and Spanish national/regional public holidays
- Include: Only Monday–Friday working days
Example timeline:
| Notification Date | 10 Business Days Deadline |
|---|---|
| Monday, December 1, 2025 | Tuesday, December 16, 2025 |
| Friday, December 5, 2025 | Thursday, December 18, 2025 (excludes weekends) |
| Monday, December 22, 2025 | Tuesday, January 7, 2026 (excludes Christmas holidays) |
Critical: The 10-day clock starts the day AFTER you receive the notification, NOT the day the letter was sent.
What Happens If You Miss the Deadline?
Immediate consequences:
- ❌ Automatic penalty imposition (minimum €150, up to €600,000 depending on infraction)
- ❌ Hacienda proceeds with its assessment by default (they assume their calculations are correct, and you lose the right to contest)
- ❌ Loss of appeal rights (you forfeit the ability to challenge Hacienda’s findings)
- ❌ Escalation to enforcement stage (providencia de apremio—formal debt collection order)
- ❌ Asset seizure authority (Hacienda can freeze bank accounts, garnish wages, seize property)
This is NOT a casual notice. A requerimiento is a LEGAL DEMAND. Ignoring it is one of the costliest mistakes non-residents make.
Part I: What Is a «Requerimiento»?
Definition: A Formal Legal Request
A requerimiento is an official legal communication from the Spanish Tax Agency (Agencia Tributaria/Hacienda) demanding that you:
- Provide documentation or information (e.g., rental income records, bank statements, invoices, contracts)
- Clarify or correct tax filings (e.g., explain discrepancies in your Modelo 210 declaration)
- Pay outstanding tax debt (e.g., settle unpaid non-resident income tax from prior years)
- Appear for an audit or meeting (less common for non-residents, more common for residents or businesses)
It is NOT:
- A friendly reminder
- An informational notice
- A suggestion
- Optional correspondence
It IS:
- A binding legal demand
- Subject to strict deadlines (10 business days)
- Enforceable through penalties and asset seizure if ignored
How Requerimientos Are Delivered
Hacienda sends requerimientos via:
- ✅ Postal mail (registered letter, Correos certified mail)
- ✅ Electronic notification (via your Hacienda electronic mailbox if you’re registered on the Tax Agency website)
- ✅ In-person delivery (at your registered Spanish address, delivered by a Hacienda official)
Important: If you’re a non-resident living abroad, Hacienda sends the requerimiento to the address you provided on your tax forms (typically your Spanish property address or a Spanish lawyer/gestor’s address).
If you never provided a Spanish address: Hacienda publishes the notification on their official bulletin board (tablón de edictos), and it’s legally considered «delivered» 10 days after publication—even if you never saw it.
This is why many non-residents miss requerimientos entirely—they don’t check their Spanish property mailbox, and by the time they discover the notice, the deadline has passed.
Part II: Why You Received a Requerimiento—The 5 Most Common Triggers for Non-Residents
Trigger #1: Failure to File Modelo 210 (Non-Resident Income Tax)
What it is: Modelo 210 is the tax form non-residents must file to declare:
- Rental income (if you rent out your Spanish property)
- Imputed income (if you own a Spanish property but DON’T rent it out—Spain taxes you on a fictional «imputed income» based on the property’s cadastral value)
- Capital gains (if you sold a Spanish property)
Deadlines:
| Income Type | Deadline |
|---|---|
| Rental income | January 1–20 (annually, for prior year’s income) |
| Imputed income (non-rented property) | December 31 (annually, for prior year) |
| Capital gains (property sale) | 3 months after sale date |
Why you received a requerimiento:
- Hacienda has no record of your Modelo 210 filing for [year]
- Example: You own a property in Málaga, don’t rent it, and didn’t file the December 31, 2024 Modelo 210 for 2023 imputed income → Hacienda sends requerimiento in 2025 demanding you file and pay the tax
Typical penalty if you don’t respond: €150–€1,500 (depending on tax amount owed)
Trigger #2: Incorrect or Incomplete Modelo 210 Filing
What it is: You filed Modelo 210, but Hacienda detected errors or omissions:
- Underreported rental income (you declared €10,000 but bank records show €15,000 in rental deposits)
- Incorrect property value (you used an outdated cadastral value, and Hacienda recalculated the imputed income)
- Missing deductions (you claimed rental expenses that Hacienda believes aren’t deductible)
- Wrong tax rate (you applied 19% rate as EU resident but Hacienda believes you should pay 24% as non-EU resident)
Why you received a requerimiento:
- Hacienda is asking you to provide documentation proving your declared figures are correct
- Example: You declared €12,000 rental income, but Airbnb reported €18,000 to Hacienda → requerimiento demands you explain the €6,000 discrepancy
Typical penalty if you don’t respond: €1,000–€10,000 (depending on the amount involved)
Trigger #3: Failure to File Modelo 720 (Foreign Asset Declaration)
What it is: If you’re a Spanish tax resident (spending 183+ days/year in Spain), you must file Modelo 720 annually (by March 31) declaring foreign assets exceeding €50,000 per category:
- Bank accounts abroad (total balance >€50,000)
- Foreign investments (stocks, bonds, mutual funds >€50,000)
- Foreign real estate (property outside Spain valued >€50,000)
Why you received a requerimiento:
- Hacienda suspects you’re a Spanish tax resident but didn’t file Modelo 720
- Example: You moved to Spain in 2023, became a tax resident, own a UK property worth £200,000 and a US bank account with $80,000, but didn’t file Modelo 720 for 2024 → Hacienda sends requerimiento demanding you file
Typical penalty if you don’t respond: €10,000 PER UNDECLARED ASSET (this is one of the harshest penalties in Spanish tax law)
Important: Modelo 720 does NOT apply to non-residents who only own Spanish property—it only applies to Spanish tax residents with foreign assets.
Trigger #4: Discrepancies Between Your Filings and Third-Party Data
What it is: Hacienda receives income reports from:
- Banks (reporting interest income, account balances)
- Notaries (reporting property sales and purchase prices)
- Rental platforms (Airbnb, Booking.com report rental income directly to Hacienda)
- Employers (if you work in Spain)
If this data doesn’t match your tax filings, Hacienda sends a requerimiento asking for clarification.
Example:
- Airbnb reported you earned €20,000 in 2024 from your Barcelona apartment
- You filed Modelo 210 declaring €15,000
- Hacienda sends requerimiento: «Explain the €5,000 discrepancy or we’ll assess you owe tax on €20,000»
Typical penalty if you don’t respond: €1,500–€15,000 (depending on amount)
Trigger #5: Outstanding Tax Debt (Unpaid Taxes from Previous Years)
What it is: You have unpaid taxes from prior years, and Hacienda is escalating collection efforts.
Escalation stages:
- Initial notification (carta de aviso): Friendly reminder about unpaid tax
- Formal notice (requerimiento): Legal demand to pay within 10 days
- Enforcement order (providencia de apremio): Formal debt collection order (adds 20% surcharge to original debt)
- Asset seizure (embargo): Hacienda freezes bank accounts, garnishes income, or seizes property
Why you received a requerimiento:
- You’re at Stage 2—Hacienda is giving you one final chance to pay before moving to enforcement (Stage 3)
Typical penalty if you don’t respond: Original tax debt + 20% surcharge + enforcement costs
Part III: How to Respond to a Requerimiento—Step-by-Step Guide
Step 1: Translate and Understand What Hacienda Is Asking
If you don’t read Spanish fluently:
- ✅ Hire a Spanish tax advisor or lawyer IMMEDIATELY to translate and interpret the requerimiento
- ✅ Use Google Translate as a temporary measure (but DO NOT rely on it for legal accuracy)
- ✅ Identify the key sections:
- What Hacienda is requesting (documentation? payment? clarification?)
- The deadline (date by which you must respond)
- The reference number (número de referencia or CSV—needed for electronic submission)
- The tax year(s) involved (e.g., «Modelo 210 for fiscal year 2023»)
Common Spanish terms you’ll see:
| Spanish Term | English Translation |
|---|---|
| Requerimiento | Official request/demand |
| Plazo | Deadline |
| 10 días hábiles | 10 business days |
| Documentación justificativa | Supporting documentation |
| Alegaciones | Written arguments/explanations |
| Propuesta de liquidación | Proposed tax assessment (Hacienda’s calculation of what you owe) |
| Sanción | Penalty/fine |
| Providencia de apremio | Enforcement order |
Step 2: Gather Required Documentation
Depending on what Hacienda is requesting, you may need:
- ✅ Rental income proof:
- Rental contracts
- Bank statements showing rental deposits
- Invoices from rental platforms (Airbnb, Booking.com)
- Rental expense receipts (if claiming deductions: property management fees, repairs, utilities)
- ✅ Property ownership proof:
- Property deed (escritura de compraventa)
- Cadastral certificate (certificado catastral) showing property value
- IBI (property tax) receipts
- ✅ Income tax filings from prior years:
- Copies of previous Modelo 210 forms
- Proof of payment (bank transfer receipts, tax payment confirmations)
- ✅ Foreign asset proof (if Modelo 720-related):
- Foreign bank statements
- Investment account statements
- Foreign property deeds
Important: All non-Spanish documents must be translated into Spanish by a certified translator (traductor jurado).
Step 3: Prepare Your Response
Your response should include:
- Cover letter (written in Spanish) stating:
- Your name, NIE (Spanish tax ID), and the requerimiento reference number
- Confirmation you received the requerimiento on [date]
- Brief explanation of your response (e.g., «I am providing the requested rental income documentation for 2023»)
- Your contact information (email, phone, Spanish address)
- Supporting documents (organized, numbered, and referenced in your cover letter)
- Signed declaration (stating the information you’re providing is accurate and complete)
Pro tip: If you’re unsure how to respond or if the situation is complex, state in your cover letter: «I am currently gathering the requested documentation and will provide it as soon as possible» — this buys you time and shows good faith, reducing the likelihood of immediate penalties.
Step 4: Submit Your Response
You have TWO submission options:
Option A: Electronic Submission (Recommended)
Portal: https://sede.agenciatributaria.gob.es (Hacienda’s electronic office)
Requirements:
- Spanish digital certificate (certificado digital) OR Cl@ve PIN (government electronic ID system)
- The requerimiento reference number (CSV or número de referencia)
Steps:
- Log in to Sede Electrónica using your digital certificate or Cl@ve
- Navigate to «Registro Electrónico» (Electronic Registry)
- Select «Presentación de escritos y comunicaciones» (Submit documents and communications)
- Enter the requerimiento CSV/reference number
- Upload your response letter + supporting documents (PDF format)
- Submit and download the confirmation receipt (justificante de presentación)—SAVE THIS
Processing: Response is timestamped and considered submitted on the date/time of upload.
Option B: Physical Submission
Where to submit:
- ✅ At your nearest Tax Agency office (Oficina de la Agencia Tributaria)
- ✅ By registered mail (Correos certificado) to the address listed on the requerimiento
- ✅ At certain post offices (Oficinas de Correos) that have registry agreements with Hacienda
Important: If submitting by mail, the postmark date counts as the submission date—so mail it with enough time to meet the 10-day deadline.
What to bring:
- Original requerimiento
- Your response letter + supporting documents (2 copies: 1 for Hacienda, 1 for you with their stamp)
- Passport or NIE card (ID)
Step 5: Confirm Receipt and Wait for Hacienda’s Response
After submitting:
- ✅ Save your confirmation receipt (justificante de presentación or stamped copy of your physical submission)—this is your proof you responded on time
- ✅ Hacienda has 6 months to review your response and issue a decision
- ✅ Possible outcomes:
- Accepted: Hacienda confirms your response is satisfactory and closes the matter
- Propuesta de liquidación (proposed tax assessment): Hacienda calculates you owe additional tax and gives you 10 days to accept or challenge
- Sanción (penalty): Hacienda imposes a fine (if they determine you committed an infraction)
If you disagree with Hacienda’s decision: You have the right to appeal (recurso de reposición) within 1 month of receiving the decision.
Part IV: Can You Request an Extension?
Yes—But Only Under Specific Conditions
You CAN request an extension of the 10-day deadline IF:
- ✅ You request it MORE THAN 3 DAYS BEFORE the original deadline expires
- ✅ You provide a valid reason (e.g., «I need time to gather documentation from abroad,» «I require a certified translation,» «I’m hiring a tax advisor»)
Example:
- Deadline: Friday, December 20, 2025
- You must request extension by: Tuesday, December 17, 2025 (3 days before deadline)
- If you wait until Wednesday, December 18 or later, extension requests are typically denied
How much time you’ll get:
- Maximum extension: 5 additional business days (total: 15 business days)
- Example: Original deadline December 20 → Extended deadline December 30 (15 business days total)
How to request an extension:
Option A: Online submission
- Log in to Sede Electrónica (https://sede.agenciatributaria.gob.es)
- Navigate to «Registro Electrónico»
- Submit a formal request (solicitud de ampliación de plazo) using the requerimiento CSV
- State your reason and requested extension length
Option B: Physical submission
- Write a formal letter to Hacienda stating:
- Your name, NIE, requerimiento reference number
- Date you received the requerimiento
- Reason for extension request
- Requested extension length (up to 5 days)
- Submit at Tax Agency office or by registered mail
Important: Extension requests are NOT automatic—Hacienda can deny them. If denied, the original 10-day deadline still applies.
Part V: What If You Miss the Deadline?
Immediate Actions to Minimize Damage
If the 10-day deadline has passed and you haven’t responded:
- ❌ Do NOT ignore it and hope it goes away (this makes the situation exponentially worse)
- ✅ Submit your response IMMEDIATELY, even if late (late response is better than no response—Hacienda often waives penalties if you respond within a few days of the deadline)
- ✅ Include a brief apology in your cover letter: «I apologize for the delay. I received the requerimiento on [date] and have been gathering the requested documentation.»
- ✅ Hire a Spanish tax lawyer IMMEDIATELY if penalties have already been imposed or if Hacienda has escalated to enforcement (providencia de apremio)
Penalties you’ll face:
| Infraction Type | Penalty Range |
|---|---|
| Failure to respond to requerimiento | €150–€1,500 (minor infractions) |
| Failure to file tax return (Modelo 210) | €100–€1,500 + interest on unpaid tax |
| Underreporting income | 50%–150% of unpaid tax (serious infractions) |
| Failure to file Modelo 720 | €10,000 per undeclared asset (up to €600,000 total) |
| Tax fraud (intentional evasion >€120,000) | Criminal prosecution + 1–4 years imprisonment |
Enforcement escalation:
If you continue to ignore the requerimiento:
- Hacienda issues providencia de apremio (enforcement order)—adds 20% surcharge to your tax debt
- Hacienda freezes your Spanish bank accounts (embargo)
- Hacienda garnishes your rental income (if applicable)
- Hacienda places a lien on your Spanish property (prevents sale until debt is paid)
Part VI: When You MUST Hire Professional Help
Do NOT Attempt DIY If:
- ❌ The requerimiento involves amounts exceeding €5,000
- ❌ The requerimiento references multiple tax years (e.g., «Modelo 210 for 2021, 2022, 2023»)
- ❌ The requerimiento mentions «propuesta de liquidación» (Hacienda has already calculated what you owe)
- ❌ The requerimiento mentions «sanción» (penalty) or «infracción» (infraction)
- ❌ The requerimiento is about Modelo 720 (foreign asset declaration—penalties are enormous)
- ❌ You don’t speak Spanish fluently (legal/tax terminology is complex even for native speakers)
- ❌ You’ve already missed the deadline
- ❌ You’re unsure what documentation Hacienda is requesting
Why professional help is essential:
- ✅ Spanish tax law is complex (non-residents face different rules than residents, and mistakes are costly)
- ✅ Tax advisors know how to negotiate with Hacienda (they can often reduce penalties or arrange payment plans)
- ✅ You have appeal rights (if Hacienda’s assessment is incorrect, a lawyer can challenge it on your behalf)
- ✅ Time is critical (attempting DIY, making mistakes, and missing deadlines forfeits your rights)
