Do Portuguese Guests Need to Be Registered in SIBA?
Do You Need to Register Portuguese Guests in the SIBA Portal?
If you run an Alojamento Local (AL) property in Portugal, you have likely heard about the requirement to register guests in the SIBA portal. Many hosts know that foreign guests must be reported, but a common question arises:
Do Portuguese guests also need to be registered in SIBA?
The answer depends on the nationality of the guest and the purpose of the reporting system. Understanding this distinction is important for hosts who want to stay compliant with Portuguese regulations while avoiding unnecessary administrative work.
This article explains the legal requirements for guest identification in Portuguese short-term rentals and clarifies when SIBA registration is required.
What Is the SIBA Portal?
The SIBA portal (Sistema de Informação de Boletins de Alojamento) is the platform used by Portuguese authorities to collect information about foreign guests staying in accommodation establishments.
This system was originally managed by SEF (Serviço de Estrangeiros e Fronteiras) and is now associated with AIMA, the Portuguese agency responsible for migration and borders.
Accommodation providers such as:
Hotels
Guesthouses
Hostels
Alojamento Local properties
are required to submit guest information when hosting foreign citizens.
The purpose of the system is to monitor the presence of foreign nationals in Portugal and ensure compliance with immigration regulations.
Do Portuguese Guests Need to Be Registered in SIBA?
In most cases, Portuguese citizens do not need to be registered in the SIBA portal.
The legal requirement applies primarily to foreign nationals, meaning guests who are not Portuguese citizens.
If your guest holds Portuguese nationality, there is generally no obligation to submit their details to SIBA.
However, hosts may still choose to collect identification information for operational or security purposes.
Why SIBA Registration Applies Mainly to Foreign Guests
The SIBA system exists to support border control and immigration monitoring. For this reason, the reporting requirement focuses on non-Portuguese citizens entering the country.
When a foreign guest stays at an Alojamento Local property, hosts must submit information such as:
Full name
Nationality
Date of birth
Identification document number
Country of residence
Arrival and departure dates
This information allows authorities to maintain records of foreign visitors staying in Portuguese accommodation establishments.
Portuguese citizens already appear in national administrative systems, which is why their stays do not typically require SIBA registration.
Identification Requirements for All Guests
Although Portuguese guests usually do not need to be reported in SIBA, hosts are still expected to verify the identity of guests staying at the property.
For operational and safety reasons, many hosts request identification from all guests at check-in.
Common identification methods include:
National ID card
Passport
Driver’s license
Verifying identity helps prevent fraud, improves security, and ensures hosts know who is staying in their property.
Online Check-in and Guest Identification
Many hosts now use Online Check-in systems to collect guest information before arrival.
Instead of manually asking for documents during check-in, guests fill in their information through a digital form.
Online Check-in systems typically collect:
Guest name
Date of birth
Nationality
Identification number
Arrival and departure dates
When the guest is a foreign citizen, this information can be used to prepare the required SIBA submission.
When the guest is Portuguese, the information can still be stored for internal records but does not need to be sent to SIBA.
Common Mistakes Hosts Make
Because the rules can be confusing, many hosts misunderstand SIBA requirements.
Some of the most common mistakes include:
Registering all guests in SIBA
Some hosts believe every guest must be reported. In reality, only foreign guests generally require submission.
Not registering foreign guests
Other hosts mistakenly assume Airbnb or Booking handles guest reporting. This is not the case — the responsibility always lies with the host.
Collecting incomplete information
If guest details are missing, hosts may not be able to submit accurate SIBA reports when required.
Other Compliance Requirements for Alojamento Local
Guest reporting through SIBA is only one part of the regulatory framework governing Alojamento Local operations in Portugal.
Hosts may also need to manage several additional obligations, including:
INE reporting through the IPHH survey
City Tax collection in municipalities that apply it
Invoicing for accommodation services
Modelo 30 reporting when receiving payments from foreign platforms
COPE compliance and financial record keeping
Managing these requirements separately can become time-consuming, particularly for hosts operating multiple properties.
Simplifying Compliance for Portuguese Hosts
To simplify administrative tasks, many hosts use platforms designed specifically for Portuguese Alojamento Local management.
Tools like EazyAL help hosts manage processes such as:
Online Check-in for guests
Preparation of SIBA submissions for foreign guests
INE reporting workflows
City Tax management
Invoicing and financial tracking
These systems help hosts stay compliant while reducing the time spent on administrative tasks.
They are particularly useful for property managers who operate multiple listings, work with or without a Channel Manager, or manage properties under one or several VAT IDs.
Final Thoughts
Understanding when to register guests in the SIBA portal is essential for hosts operating short-term rentals in Portugal.
In most cases:
Foreign guests must be registered in SIBA
Portuguese guests do not need to be submitted
However, hosts should still verify guest identity and maintain accurate records for operational purposes.
By implementing a structured check-in process and using digital tools to manage compliance tasks, hosts can ensure they meet regulatory requirements while focusing on delivering a great experience for their guests.
For many Portuguese hosts, solutions like EazyAL provide a simple way to manage guest registration, reporting obligations, and day-to-day operations in one place.
