Spain's 2026 Tax Control Plan: What Non-Resident Property Owners Need to Know

Spain’s Tax Agency (AEAT) has published its 2026 Tax Control Plan, confirming a clear direction: more digital control, more data, and stronger enforcement—especially in areas like real estate and cross-border income.

If you own property in Spain as a non-resident, this matters more than ever.

What Is the 2026 Tax Control Plan?

The plan is based on the Strategic Plan 2024–2027 and focuses on improving compliance through:

• Better taxpayer assistance

• Prevention of errors and non-compliance

• Stronger investigation of tax fraud

• Improved debt collection

• Increased cooperation with regional authorities

The goal is not just to audit more—but to detect issues earlier using data and automation.

Key Changes in 2026

Expanded financial data collection

The AEAT will now have access to significantly more financial information, including:

• Monthly data on bank account ownership

• Monthly data on card payments and mobile payments

• New reporting linked to digital assets and platforms (DAC8 directive)

This allows the tax authority to detect undeclared income much faster than before.

Stronger control of real estate activity

The 2026 plan confirms increased focus on the property sector, including:

• Property ownership

• Rental activity

• Property sales

This directly impacts non-residents who:

• Rent out their property

• Do not rent it (imputed income still applies)

• Sell property in Spain

Increased monitoring of digital platforms

The AEAT is strengthening control over:

• Rental platforms (Airbnb, Booking, etc.)

• E-commerce and digital income

• Online payment systems

This means rental income is now easily cross-checked against tax filings.

Focus on hidden income and lifestyle discrepancies

A key priority is identifying:

• Undeclared income

• Assets not properly reported

• Mismatches between lifestyle and declared income

This is done by combining:

• Financial data

• Property ownership data

• Platform and international reporting

More cooperation and data sharing

The AEAT will increase cooperation with:

• Autonomous communities

• EU tax authorities

• International reporting systems

This improves their ability to cross-check:

• Property ownership

• Transactions

• Foreign income

What This Means for Non-Resident Property Owners

The 2026 plan significantly increases the risk of being flagged if something is missing or incorrect.

Main risk areas

• Rental income not declared

• Imputed income not filed

• Capital gains not correctly reported

• Wealth tax exposure not reviewed

Why enforcement is now stronger

The key change is how enforcement works:

Before:

• Random audits

• Limited data

Now:

• Continuous monitoring

• Automatic data matching

• Faster detection

In many cases, the tax authority already has the information before reviewing your tax return.

What You Should Do

To stay compliant in 2026:

• File Modelo 210 correctly (rental or imputed income)

• Declare capital gains after selling property

• Review whether wealth tax applies

• Ensure consistency with your home country tax reporting

• Keep proper documentation

Final Takeaway

Spain’s 2026 Tax Control Plan confirms a clear trend:

• More data

• More automation

• More control

For non-resident property owners, the biggest risks remain:

• Missing rental income declarations

• Missing imputed income filings

• Incorrect handling of property sales

The difference now is that these issues are much easier for the tax authority to detect.

Taking a proactive approach is no longer optional—it’s essential.
