I'm not sure if posting in this section is appropriate. Please correct me if I'm wrong.

1. If we make money through stock market trading (SMT), do we still have to pay income tax? Not so clear in the Financial Budget for 2024...

2. I've heard that the "frequency of trading" is the point. However, I'm having trouble finding its specific rules. How do we assess? (Assume that I buy and sell in a span of two days, one week, sometimes longer than a month.)

3. Can we include other costs like water and electricity bills, computer maintenance, hardware purchases, and so on? I didnt registeringmy in SSM, but under my own name only.

4. Should I use the Borang B or BE when e-filing? (Because I make my own money)

Thanks in advance for the helps!

As long as we EARN profit on any legal channel ("gains or profits not falling under any of the foregoing classes"), we have to pay tax.
Either individual or company.

You are right. It's too ambiguous, not much information after surfing online.
