Thanks again bro
Appreciate your explanation, it help me a lot ! I understand much better now
I am tax payer but sometimes I might not taxable for 1~2 months ( if I don't do overtime). If let say my total tax per year is ONLY RM1000, I still can claim up to RM8000 provided got receipt under personal relief ?

Well, we have to differentiate between reliefs and rebates. Reliefs in a way reduces your taxable income, and as for rebates, it reduces your tax payable. That's the different.
As for monthly tax deduction, usually stated as PCB (Potongan Cukai Bulanan) or STD (Schedular Tax Deduction), it depends on your current marriage status and also how many kids you have, then your employer deduct it accordingly. They have the deduction table and they just follow there. As far as I know from the deduction table, deduction starts if your monthly salary is RM2,500 and above. You can refer the table here. However, i think there will be 2008 ammendment due to rate changes starting YA2008.
You can refer the table here. PCB deduction table doesn't take into account of any other reliefs, other than your EPF contribution, self relief, wife relief and children reliefs.
The big question, how do we claim the other reliefs that we can claim, like insurance, books, medical expenses, etc? At the end of a year, your employer will give you a form called Borang EA. This form is a summary of your gross taxable income, your EPF contribution and your PCB paid. When the IRB opened their e-filing website, login to your own form and fill it. When it comes to the reliefs part, just key in the amount that you want to claim (books, insurance, etc), and the e-filing system will automatically compute your tax. Then you will know whether your monthly deduction is enough to cover your tax payable for that year or not. If not enough, you can use maybank2u to pay, and if overpaid, just wait for refund from the IRB.
