Income Tax Computation

Compute chargeable income = gross income − reliefs, apply the tax bands, and subtract a rebate to find the tax payable.

How income tax is computed

In Malaysia an individual is taxed on chargeable income, not the full salary. First subtract all tax reliefs (EPF, life insurance, education, medical, etc.) from gross income, then apply the tax rate bands to what remains.

Key formula

$\text{Chargeable income} = \text{gross income} - \text{total reliefs}$. Tax is charged band by band; a tax rebate is then subtracted from the tax charged to give the tax payable.

Worked example

Worked example

Bands: first RM5,000 at 0%; next RM15,000 at 1%; next RM15,000 at 3%. Gross income RM48,000 and total reliefs RM16,000 give a chargeable income of $48000 - 16000 = \text{RM}32{,}000$. Tax $= 15000(0.01) + 12000(0.03) = 150 + 360 = \text{RM}510$. Since chargeable income does not exceed RM35,000, a rebate of RM400 applies, so tax payable $= 510 - 400 = \text{RM}110$.

Remember

  • Reliefs reduce chargeable income; a rebate reduces the tax itself.
  • Tax is charged band by band, not all at the top rate.
  • Write all amounts as RM, never with a bare sign.
