What documents do I need to renew my one-year retirement visa in Thailand for the first time?

Residence certificate has never been a part of retirement visa or extension. Go to your immigration office and ask them for their handout for 1-year retirement extension. Each office has their own requirements and they change from time to time. The only way to know what you need for sure is to go there and ask for their handout.

These are common requirements but you need to find out directly from your immigration office.
