HLB Thailand Tax Team


The Thai Cabinet has approved the proposal of the Social Security Board to reduce contributions for both employers and employees from the current 5% rate to 2.5% for three months from June to August 2021, to alleviate the suffering of insured persons from the impact of Covid-19. 

The monthly wage base for contributions ranges from THB 1,650 to a maximum of THB 15,000 for each employee. 

The maximum contribution will therefore be reduced to THB 375 per month for both employers and employees for the three months from June to August 2021.

Monthly contributions by voluntary insured persons under Section 39 of the Social Security Act have also been reduced to THB 216 per month (from THB 432 per month) for three months from June to August 2021.

For social security contributions filed electronically for the 2021 year, the filing date is extended for seven working days. The extended filing deadlines for the remainder of the year are summarized below.
