The status of a resident will let you avoid double taxation under Serbian DTTs with nearly 60 countries. Residents can buy property in Serbia. For residents it is easier to open a corporate account in Serbia with the local banks. Among other benefits of the legal residence is the banking/financial confidentiality, because Serbia has not yet started automatic exchange of financial information about its residents with other countries. Please note that if you apply for opening a branch of a foreign company in Serbia you as a foreign investor can qualify both for opening a bank account in Serbia and for a residence permit.
