Q1012. What are the Thai social security contribution rules?
Answered by the NYC Visa & Translation accounting and tax team
Under the Social Security Act B.E. 2533, an employer with one or more employees must register within 30 days of hiring. Section 33 contributions are ordinarily 5 percent from the employee and 5 percent from the employer, computed on a monthly wage ceiling of THB 17,500, maximum THB 875 per person per side from 1 January 2026 to 31 December 2028; check temporary reductions. Contributions are not registration fees. Contributions and form SPS.1-10 are remitted by the 15th of the following month. Temporary rate reductions have been made by ministerial regulation in the past, so verify the rate for the month being filed. Ask our Thai accounting team to review your position by phone, LINE or email before you file.
Based on the Revenue Code, the Accounting Act B.E. 2543 and related law as at August 2026. General information only, not advice on a specific matter — verify with the Revenue Department (rd.go.th) before acting.
