Hello,
The thing is louiss ... you better make it faster. The latest tax submition for self-employed is 30 June (if I not mistaken). If you missed it you have to pay fine. 10% of your tax payable.
How long you already go venture in blogging business ? Better declare ALL years of income. Why ?
Let say the LHDN people pinpoint you and start the investigation. The calculate you CURRENT year blogging income. Let say RM 50,000 yearly. Then they just multiply it with UNDELCARED years of your income.
By the way, do not try to cheat them. All of Tax Investigation are top people

their starting payment is RM 3800. To join the team you must have EXTENSIVE general knowledge + few specialise knowledge which Govt tested during interview.
So ... please be honest in declaring, please do not think that they DO NOT know about blogging
Thank you,
