How to Correct Errors in Modelo 210 (Amending, Late Filing, Penalties) – 2025 Guide

If you’re a non-resident property owner in Spain, you’ve likely heard of Modelo 210 — the Spanish tax form used to declare income from Spanish properties. But what happens if you make a mistake, forget to file, or need to amend a previous declaration?

This in-depth 2025 guide explains everything you need to know about correcting errors in Modelo 210, filing late returns, avoiding penalties, and how Taxadora can help you fix things quickly and stay compliant.

✅ What Is Modelo 210?

Modelo 210 is the tax form non-residents must use to declare:

• Renta imputada (imputed income on personal-use property)
• Rental income (from short- or long-term lets)
• Capital gains (e.g., after selling property in Spain)

It’s filed annually for renta imputada and quarterly for rental income.

If you fail to file, or file incorrectly, Spain’s tax authority (AEAT) can impose interest, surcharges, and penalties — even if you didn’t owe much tax.

🧾 Common Mistakes in Modelo 210

Here are the most frequent errors we see:

• Filing the wrong use type (e.g., declaring rental instead of imputed income)
• Using the wrong cadastral value or outdated reference
• Forgetting to convert foreign rental income into EUR using the official rate
• Skipping co-owner declarations (each owner must file separately)
• Not filing at all
• Reporting on the wrong timeline (e.g., rental filed annually instead of quarterly)

Even minor mistakes can trigger a review by AEAT or delay property sales.

🛠️ How to Correct a Mistake in Modelo 210

If you’ve already submitted a Modelo 210 and realized it’s incorrect, you can file a request to amend it to fix the mistake. How to do this depends if you have paid too little or too much taxes.

🕒 What If You File Late?

Late filing is common — especially for non-residents who aren’t aware of Spanish deadlines.

If you miss the deadline, here’s what happens:

🧾 If You File Voluntarily (Before AEAT Notices)

• Late surcharge of 1% + 1% per additional month (up to 12 months)
• No penalty if filed voluntarily within 12 months

🚨 If AEAT Detects It Before You File

• Minimum penalty of often €150–€300
• Plus interest and late surcharges
• May affect future property transactions or tax refunds

⚠️ Penalties for Not Filing or Filing Incorrectly

• Surcharge of 5%, 10%, or 20% (depending on how late)
• Fines starting often at €150
• If underreporting income: 50%–150% of unpaid tax
• Interest for late payment (legal interest rate + penalty interest)

AEAT shares information with:

• Spanish property registries
• Utility companies
• Local councils (IBI)
• Rental platforms like Airbnb, Booking.com

This allows them to cross-reference your usage and rental income.

✍️ Case Study: Swedish Couple Files Late

Anna and Lars, Swedish non-residents, forgot to file Modelo 210 for their Marbella home in 2023. In 2025, they want to sell the property.

The notary requests proof of Modelo 210 compliance. They:

• File late returns for 2021–2023
• Pay renta imputada with interest and late fees
• Avoid higher penalties by filing voluntarily before AEAT contact

✅ Sale proceeds without delay thanks to late compliance

🔁 Can You Claim Refunds on Overpaid Modelo 210?

Yes. If you overpaid or filed the wrong use-type (e.g. paid rental rate on personal-use), you may be eligible for a refund.

How:

• File a rectificación de autoliquidación (corrective return)
• Submit written request for refund
• Attach proof (e.g. no rental income, utility bills, or stays)
• AEAT typically replies within 6-12 months

If denied, you can file an administrative appeal or go to tax court.

🔄 What If You Missed Multiple Years?

Taxadora regularly helps clients file Modelo 210 backdated returns for up to 4 years.

• You can catch up without major penalties if you file voluntarily
• AEAT statute of limitations is 4 years, but property sales or audits can trigger longer reviews
