On December 12, 2025, Thailand's Ministry of Labor published
a ministerial regulation prescribing the minimum and maximum wages
used as a base for calculating social security contributions. The
regulation, which takes effect on January 1, 2026, sets a flat
minimum base wage of THB 1,650 per month and a phased increase of
the maximum base wage over the following six years, as outlined in
the table below.

Impact on Social Security Benefits
Not only will monthly contributions increase as a result of the
adjustment to the maximum wages used as a base for calculating
social security contributions, but the maximum benefits available
to insured persons will also be enhanced, as shown in the next
table.
