EXPAT TAX

Hello,

I was employed by a BPO company in June 2018. Since then I didn't go out of Malaysia. My contract now has ended, 10 June 2018, but Hasil is charged me 6k plus of tax (28%), this was deducted from my final pay. Is this correct?

As far as I understand, I should be treated as Resident Tax payer since I stayed  in Malaysia for more than 182 days.

Can someone confirm this? If Hasil made a wrong computation of my tax, can I claim a refund? 6k is very huge amount for me. :(

Thank you for your advise in advance.

Sorry, end of contract is 10 June 2019.
