International treaties:

• Tax rates may be lower under double taxation treaties concluded with the country in which the taxpayer's registered office or management board are located.

Certificate of Residence:

• Tax rates envisaged in the double taxation treaties may be applied only if a taxpayer holds a certificate of residency issued by the given country's tax authorities.
