13. How to calculate tax on salary?
(90 combined monthly Google searches in Malaysia)
Many Malaysians search for this because salary tax isn’t always as straightforward as it seems. Between PCB deductions, reliefs, rebates, and progressive tax rates, it’s easy to get confused about how much tax you actually owe. The good news is that once you understand the basic structure, salary tax becomes much easier to calculate.
Here’s a clear breakdown to help you navigate it with confidence:
Step 1: Determine your total annual income
Start with your gross annual salary, which includes:
- Monthly wages
- Bonuses
- Overtime
- Commissions
- Allowances (unless specifically exempted)
This gives you your annual taxable income before deductions.
Step 2: Apply allowable deductions
Malaysia offers several deductions that help reduce your chargeable income, including:
- EPF contributions
- SOCSO/EIS contributions
- Lifestyle deductions
- Insurance premiums
- Medical expenses for parents
- Education fees
- PRS contributions
Your total income minus all allowable deductions gives you your chargeable income.
Step 3: Apply Malaysia’s progressive tax rates
Malaysia uses a tiered tax system, meaning higher portions of your income fall under higher tax brackets. As of YA 2024, rates range from 0 percent to 30 percent.
To calculate tax manually:
- Break your chargeable income into the appropriate tiers
- Apply the corresponding tax rate for each tier
- Add up the results
This gives you your gross tax payable.
Step 4: Apply tax rebates (if eligible)
Malaysia offers tax rebates such as:
- Self rebate (if chargeable income is below a certain threshold)
- Spouse rebate
- Zakat rebate (equivalent zakat payments can offset your tax)
Rebates directly reduce your tax payable.
Step 5: Subtract PCB deductions
PCB (Potongan Cukai Bulanan) is the amount your employer deducts from your salary for tax throughout the year. After calculating your total tax payable:
Final Tax Payable = Actual Tax Owed – PCB Already Deducted
- If PCB exceeds what you owe, you’ll receive a refund
- If PCB falls short, you’ll have to pay the balance
Accurate salary tax calculations help employees stay compliant and give businesses more confidence in their payroll processes.
