If you have ever looked at your payslip and wondered why your take-home pay is less than your gross salary, the answer is in statutory deductions. These are payments your employer is required to make on your behalf, such as EPF, SOCSO, EIS, and PCB.

What Does PCB Stand For?

PCB stands for Potongan Cukai Berjadual (Monthly Tax Deduction in English). It is your monthly income tax deducted by your employer to cover your estimated tax liability for the year.

The deducted amount goes directly to Lembaga Hasil Dalam Negeri or LHDN, Malaysia’s Inland Revenue Board. By the time you file your annual tax return typically between March and April, you’ve already paid most or all of your tax for that year through these monthly deductions.

Understanding Your Payslip

Here’s how PCB appears on a payslip for someone earning RM5,000 a month:

Item	Amount (RM)
Gross salary	5,000.00
Mandatory Deductions / Tax
EPF 11%	550.00
SOCSO	39.25
EIS	15.45
PCB (Income Tax)	346.00
Net salary / Take-home pay	4,049.30

The PCB amount varies depending on your salary and personal circumstances. Some employers include a year-to-date total on your payslip, so you can track how much has been deducted so far.

How Your Employer Calculates PCB

The monthly PCB is an estimate, not simply your annual tax divided by 12. It takes into account progressive tax rates, reliefs, and other adjustments to calculate your deduction as accurately as possible. Employers use LHDN’s formula to estimate your monthly tax deduction based on a few key factors:

• Monthly salary – your gross income, including basic pay and fixed allowances.
  
• Deductions and reliefs – certain contributions and personal reliefs reduce your taxable income.
  
• PCB schedules – LHDN publishes tables that show how much tax should be deducted for different salaries and circumstances.
  

You can also use LHDN’s online PCB calculator to estimate your monthly PCB based on your salary and personal circumstances.

Is PCB Your Final Tax Payment?

No. PCB is an advance payment based on estimates. When you file Form BE between March and April, LHDN calculates your actual tax bill, and that’s when you find out if you’ve paid too much, too little, or hit it exactly right.

Your employer will provide you with an EA form (usually by February or March). This form summarises your total income and the PCB deductions for the year. You’ll use this form to fill out your Form BE, which is your official tax return. 

LHDN then calculates your exact tax based on everything: your actual annual income including bonuses or overtime, all the tax reliefs you claim like lifestyle spending, insurance premiums, EPF contributions and medical expenses, plus any other deductions you’re eligible for.

The most common outcome is getting a refund. If your total PCB deductions exceed your actual tax liability, LHDN refunds the difference to your bank account, usually within 30 days of processing your return.

Sometimes you’ll owe additional tax. If your PCB deductions don’t cover your full tax liability, you pay the balance to LHDN. This typically happens when you received bonuses, commissions, or other irregular income throughout the year that weren’t reflected in your monthly PCB.

Common Situations That Affect Your PCB

Your PCB deduction can end up being too high or too low for several reasons:

Bonuses and irregular income: If you received a RM10,000 year-end bonus, your PCB calculations for the year didn’t account for this extra income. When you file your taxes, this bonus pushes your annual income higher, potentially moving you into a higher tax bracket and creating a balance to pay.

Mid-year job changes: If you changed jobs in July, your new employer only knows about your salary from July onwards. They don’t know you were earning RM6,000 at your previous job from January to June. Your PCB at the new job might be too low because it’s based on incomplete annual income information.

Tax relief claims: You bought RM2,500 worth of lifestyle items like books, computers and sports equipment, paid RM3,000 in life insurance premiums, and spent RM1,000 on medical expenses. Your employer’s PCB calculation probably didn’t include these reliefs, meaning you’ll get a refund when you file your taxes.

Marriage or children: If you got married or had a child during the tax year, your tax reliefs increased but your PCB might still be based on your previous status. You’ll likely see a refund when you file.

Multiple income sources: If you’re doing freelance work on weekends or have rental income, your employer has no way of knowing about this. Your PCB only covers tax on your employment income, so you’ll have additional tax to pay on your other income sources.

Do You Still Need to File Taxes If PCB Is Deducted?

Yes, you still need to file your taxes. All Malaysian residents earning above RM37,333 per year (after EPF deductions) must file Form BE annually, even if PCB has been deducted. 

Filing your tax return lets you claim your full reliefs since many can only be claimed through your annual return and not through PCB. You also get to declare all income if you had multiple jobs or freelance work, and receive your refund if you overpaid through PCB.

The deadline for filing is typically 30 April for manual filing and 15 May for e-filing. Missing the deadline can result in fines up to RM20,000 or imprisonment up to 6 months, plus a 10% penalty on any tax owed.

What To Do If You Think Your PCB Is Wrong

Update your tax relief information: If your circumstances have changed since you started your job such as getting married, having a child, or becoming eligible for new reliefs, submit a TP1 form to your HR department. This form tells your employer about your tax relief eligibility so they can adjust your PCB. If you’re a new employee with previous employment income this year, you should have filled out a TP3 form instead.

Talk to your employer: If there’s a significant discrepancy, speak with your HR or payroll department. They might have made an error applying the PCB schedule, or you might need to update your information.

If it’s already near the end of the tax year, it might be easier to just file your return and sort out any overpayment or underpayment then, since your tax return is where everything gets properly settled anyway.

Keep In Mind

While PCB ensures that you pay your taxes in instalments throughout the year, it’s important to remember that it’s only an estimate. Filing your annual tax return is essential to settle your final tax amount.

Be sure to declare all your income, claim eligible reliefs, and keep track of your payslips and EA form to assist with your filing.
