Aloja - Portuguese Rental Compliance Automation
Automates AL license management, SEF guest reporting, and municipal tourist tax filing for short-term rental hosts in Portugal.
Portuguese short-term rental (AL) hosts must manually navigate SEF guest registration, municipal tourist tax filings, and license renewals across increasingly fragmented municipal rules. The 2024 decentralization of AL regulations to individual municipalities has made compliance a confusing, time-consuming, and error-prone process that risks fines or license revocation.
