Chekin collects the required guest data during online check-in and files the Accommodation Bulletin with SEF/AIMA through the SIBA portal — automatically and within the legal deadline, up to 3 days after arrival, with zero manual work.
Mandatory reporting to SEF/AIMA through the SIBA portal (Accommodation Bulletin Information System). It applies to every guest, nationwide, and is the main legal obligation for anyone who provides lodging.
Data filed with SEF/AIMA must be kept securely for 1 year, for audits and inspections. Chekin collects only the legally required fields and stores them encrypted, fully compliant with the GDPR.
An adaptive form that captures document, full name, nationality, date of birth and length of stay — all validated before submission.
The Accommodation Bulletin is filed to the SIBA portal the moment a guest completes check-in. One integration covers every property.
Submissions are scheduled to meet the legal deadline — the first working day after arrival. You get an alert whenever something needs attention.
We collect only the legally required fields and store them encrypted. GDPR compliance by default, with no loose spreadsheets in sight.
Every bulletin is kept for the year required by law, encrypted and ready for any inspection by the authorities.
Every bulletin is stored, time-stamped and exportable. When an inspection comes, it's all one click away. E-invoicing (AT) ready when you need it.
In Portugal, invoicing is overseen by the Autoridade Tributária e Aduaneira (AT). E-invoicing is currently voluntary for most B2B and B2C transactions, but businesses with an annual turnover above €50,000 must use certified software in the SAF-T / ATCUD format for invoicing and reporting.
Chekin is ready to integrate with certified invoicing systems, so you stay compliant as e-invoicing becomes mandatory for more businesses.
Read moreIn Portugal the tourist tax is set at municipal level but stays broadly consistent across cities, and is charged for a maximum of seven nights. The amount depends on factors like the number of nights, guest age and type of accommodation.
Hosts must collect the tax during the stay, communicate it to guests in advance and keep accurate records. Chekin is fully configurable to local municipal rules and automates the calculation, collection and reporting — fewer errors, less admin.
The guest fills in the registration form with their info, verifies their identity, and signs before submitting.
Chekin builds the digital Accommodation Bulletin from the guest's data, in the exact format the SIBA portal requires.
Automatic submission to SEF/AIMA through the SIBA portal, within the legal deadline — with no work from the host.
Every bulletin is archived and kept for 1 year. You see the status of each filing in your dashboard, with alerts if anything needs attention.
The check-in form asks only for the legally required fields, validates them on the spot, and delivers them to the authorities in the format they expect. Easy for you, quick for your guests, and GDPR-compliant.
Reporting to SEF/AIMA is mandatory for every accommodation, without exception. Fines range from €100 to €40,000, with the risk of license suspension for repeat cases — on top of GDPR penalties for mishandling guest data.
