Do I need to do 90-day reporting after getting my work permit in Thailand?

After receiving a work permit in Thailand, the original poster was confused about the requirement for 90-day reporting. The school manager initially indicated that reporting was not necessary for a year, but later suggested it was required in 2 months and 15 days. Comments clarified that 90-day reporting is typically needed depending on the visa class held, with a yearly extension of stay needing to be applied for based on employment for accurate reporting timelines. A yearly extension will provide the necessary information about when to report.
