I am in your position, I'm freelancing for a UK company earning $3k/month. They pay me through Transferwise which I then transfer out to my local bank account.

Just talked to LHDN on this issue last week, here is what they told me.

If your income is taxed from the source country, you will not need to pay double the tax in MY (meaning tax free). But if your income is not taxed from the country of origin (ie, you get the full pay/gaji kasar), you will need to declare and pay the income tax in Malaysia IF you are a tax residence residing in Malaysia for more than 180 days.

Pretty sux eh? I though I'd get the zero income tax... 🤷🏻‍♂️

Oh well, since you're getting tax for it, might as well create your own company to receive the overseas income so that you can actually use it for loan approval lol. (Doing it this year for my overseas income)
