What is the take-home pay on 30,000 baht?

About 28,960.42 baht: 164.58 baht tax withheld and 875 baht social security, if only the personal allowance and social security were declared.

What is the most social security takes?

From 1 January 2569 the wage base is capped at 17,500 baht at 5%, so at most 875 baht a month.

Section 50(1) adds whatever doesn’t divide evenly to the last withholding of the year, so December is slightly higher.

Employers use the allowances you declare on ล.ย.01. Without them the monthly withholding may be more than you owe.
