Guys, I'm still very new to this income tax thing.
I started work since mid 2008 , first company salary RM1800.
Second company on year 2009 with RM2000 salary.
Question 1 - So I suppose I don't have to submit tax right? I didn't open a tax file yet.

Year 2010 December, I stop my employment and started a Sole Prop.
Question 2 - When do I need to start my income tax submission?
Q3 - I understand that there's personal incometax and company's which category do I need to do?
