Real Decreto 933/2021 is a Spanish regulation that requires hosts and accommodation platforms to collect and report guest registration data to the Spanish Ministry of the Interior. This law aims to enhance security and prevent criminal activities within the vacation rental sector.

Understanding Real Decreto 933/2021

Effective from January 2, 2023, with a transition period until October 1, 2024, this decree mandates that all properties located in Spain must comply with guest registration requirements. After the transition period ends, non-compliance can result in significant fines ranging from €100 to €200,000 depending on the severity of the infraction.

When Did This Law Come Into Effect?

The regulation came into force on January 2, 2023. The transition period lasted until October 1, 2024. After this deadline, hosts must ensure full compliance to avoid penalties:

• Minor infractions: €100 to €600
• Serious infractions: €601 to €30,000
• Very serious infractions: €30,001 to €200,000

How Real Decreto 933/2021 Affects Hosts

If you have properties in Spain listed on Holidu, you must report guest and booking details within 24 hours after each check-in. This regulation applies to all properties located in Spain, regardless of whether you are a Spanish resident or your nationality.

What Information Must You Report?

As a host, you must collect and report the following key data:

• Your host details and property information
• Complete guest information, including all occupants in the booking
• Booking and transaction details

Mandatory guest information includes:

• Full names of all guests
• Date of birth
• Residential address
• Contact details (phone number or email address)
• ID type and number (for all adults)
• Spanish ID support number (NIF or NIE) for applicable guests
• Relationship to minors (when applicable)

How Holidu Helps You Comply

Holidu simplifies compliance with Real Decreto 933/2021 through its online check-in feature. As an intermediary platform, Holidu automatically collects transaction data and securely reports guest information to the Spanish Ministry of the Interior via the SES Hospedajes platform within 24 hours after bookings become non-refundable.

What Steps Must You Follow to Submit Data Through Holidu?

To set up guest registration reporting through Holidu, follow these steps:

1. Register on the SES Hospedajes platform at the Spanish Ministry of the Interior official website
2. During registration, select the option "Send communications via webservice"
3. Activate the Guest Online Check-in feature in your Holidu account
4. Choose your relevant reporting authority: SES Hospedajes (for most of Spain), Mossos d'Esquadra (for Catalonia), or Ertzaintza (for the Basque Country)
5. Enter your login credentials from your selected authority platform

Once configured, Holidu automatically sends guest details to the appropriate authorities by 11:00 PM on the check-in day. Guests complete their information through an online check-in form that Holidu emails them, which they can access directly from their booking details.

How Holidu Reports Data Automatically

Holidu automatically reports booking information to the Spanish Ministry of the Interior. If a non-refundable booking is later cancelled, Holidu will update the SES Hospedajes platform to withdraw the previously reported booking information. While you cannot view a complete list of reported bookings, you can verify reported data by checking confirmed and non-refundable bookings in your Holidu account.

Important Reminders for Hosts

Even though Holidu reports data automatically, you remain responsible for ensuring all mandatory guest information is collected and accurate. If any information is missing from the online check-in form, collect it directly from guests upon arrival. Always verify that you have activated the online check-in feature, selected the correct reporting authority, provided accurate login credentials, and confirmed that the "Send communications via webservice" option is enabled on your authority platform.
