2. Hi People Team,
I just joined Gojek last September 5. This morning I just received my first salary and payslip. However, I was a little confused regarding taxation because my tax on the payslip was quite large so the nominal take home pay (THP) I received was smaller than I expected. Can you help with this? Or who can I ask?
Thank You.
Best regards, 

Tasya
