A Certificate of Income is the National Tax Service's official confirmation of your reported comprehensive income, commonly required for visa extensions, loans, or lease deposits (jeonse). If you have no filing history, a "no filing record" certificate is issued instead, and there can be a processing delay right after filing before it updates in the system.
A Certificate of Residence is issued when you need to prove Korean tax residency to claim treaty benefits (like a reduced rate) in your home country. Submit the "Certificate of Residence Application" on Hometax to have it issued online.
What you need to issue a certificate
Issuance can be delayed right after filing
Right after the May comprehensive income tax filing, it can take from several days to a few weeks for the record to update in the NTS system. If you're on a tight deadline (a visa extension, for example), check with the tax office in advance to confirm the record has been updated.
