Hello
i know there's alot of confusion here. You may wish to speak to an officer in Bahagian Teknikal of IRB and get the clarification straight.
Basically, in the absence of a permanent esablishment in the UK, the IRB may view that this income is derived from Malaysia and hence subject to tax in Malaysia. I believe u do not conclude sales etc in the UK? if you are not taxable in the UK then i would think the IRB may tax that income inMalaysia.
But then again, calling Bahagian Teknikal and get it cleared is the best. You may wish to even write in to them and tell them the entire situation (you can write in english la!)...it will probably take them 2-3 months to revert with a written clarifications. SO written is better than verbal right?
First thing first...call the IRB Bahagian Teknikal. General line is 03-6209 1000. good luck
