When switching from Digital Nomad to Cuenta Propia, regional authorities increasingly ask for proof that the applicant really worked during the previous permit.
Galicia: reviewed in about a month; after a request for proof of previous activity, a four-year permit was granted. Tenerife: requests for evidence of activity covering the whole digital nomad period, including invoices, tax returns and other documents. Alicante: positive decision for the main applicant with no request; decisions for family members were still pending at the time. Tarragona and Asturias: positive practice without significant difficulties. Castilla y León: described as unfavourable for this type of modification, without a specific decision or refusal text.
Practical takeaway: for a switch to Cuenta Propia, keep evidence of real professional activity for the entire previous permit period. Regional differences need to be assessed separately.
