Hope you can help me regarding percentage tax.
Here are my questions:

1. Do I need to file tax just per month? or I am also required to file quarterly and annually?

2. Do I need to keep a book of accounts if I’m a percentage tax?

3. Can I just file my tax by myself without the need for an accountant?

4. Can I file tax online if I’m percentage tax?

Your help are much appreciated.

Thank you!
