Hi Guys, newbie here.

Im just wierded out. My first time on income tax.
I just did a look around and found this : https://ringgitplus.com/en/blog/Personal-Fi...Guide-2015.html

1.Based on there. My salary is 4500 per month. Does it mean i dont have to pay tax?
2.Or thats annually?
3.If so, then roughly does it mean my taxable income would be (4500*12)-(standard tax relief 9000+6000)= 54000-15000=39000 [roughly here means ignoring other tax relief] = i will be in the 11% tax bracket?
4.If so, lets say i want to add in another tax relief which lets say a computer at max 3000 and books max 1000. So 39000 - 4000 = 35000 which made me fall under the 6% tax bracket. Does it mean that LHDN will pay me back the 4-5% difference that i had paid?
5.If so how much is that roughly?

Thaaaanks.

Thank you but can explain the less rebate is from where?

Thanks.
