What is the SSO contribution ceiling in Thailand for 2026?

From 1 January 2026, the SSO wage ceiling increased from THB 15,000 to THB 17,500 per month. This means the maximum monthly contribution per party — employer and employee — is THB 875, up from THB 750. The ceiling will rise again in January 2029 and January 2032 as part of a phased government reform.
