How to Submit a Sole Proprietor Tax Declaration in Slovakia?
A tax declaration in Slovakia can only be submitted online through the portal of the Financial Administration of the Slovak Republic (Finančná správa); this requires access to an electronic account and activated electronic identification. For foreigners without permanent residence in Slovakia, it is important to consider that if you need to obtain income confirmation for residence permit renewal or certificates from the tax authority for a bank (e.g., when applying for a loan), you must appoint a trusted person to receive official correspondence. For this reason, we recommend using our services to avoid administrative complications and delays.
