What Is PCB Tax in Malaysia? Monthly Tax Deduction Explained
PCB tax, also called Monthly Tax Deduction or MTD, is the monthly income tax deduction taken from an employee's salary and paid to LHDN by the employer.
If you see PCB or MTD on your Malaysian payslip, it means part of your salary has been deducted as an income tax instalment. PCB stands for Potongan Cukai Bulanan, while MTD stands for Monthly Tax Deduction. Both terms refer to the same system.
PCB is not a separate tax. It is a monthly deduction that helps employees pay estimated annual income tax gradually throughout the year instead of paying one large amount after filing.

Why PCB Exists in Malaysia
Malaysia's PCB system was introduced so income tax can be collected gradually through payroll. The Malaysia Government Portal explains that Monthly Tax Deduction helps reduce the year-end tax burden and supports regular tax compliance.
Without PCB, many employees would need to pay their full annual income tax after filing. With PCB, tax is spread across the year through monthly salary deductions.
For Employees
PCB reduces the chance of a large year-end tax bill because tax is paid monthly through salary.
For Employers
Employers deduct PCB from eligible employees and remit the amount to LHDN.
For Filing
PCB paid during the year is compared with final tax payable when annual tax is filed.
PCB vs MTD vs Income Tax
PCB, MTD and income tax are related, but they are not exactly the same. PCB and MTD describe the monthly deduction system. Income tax is the final yearly tax calculated after annual income, deductions, reliefs and rebates are considered.
Who Is Subject to PCB?
PCB usually applies to employees whose income is high enough to create an estimated income tax liability. The Malaysia Government Portal lists a minimum annual income subject to PCB of RM37,333.
Whether PCB appears on your payslip depends on your salary, tax residency, EPF, marital status, dependants, tax relief information and payroll setup. Some employees with lower salary may have no PCB deduction because the estimated monthly tax is zero.
How PCB Is Calculated
PCB is generally calculated by estimating annual taxable income, applying the relevant tax treatment, then spreading the estimated tax across the remaining months of the year. Payroll systems may use LHDN's PCB schedule, e-PCB, or approved computerised calculation methods.
The simplified idea is:
Start with monthly taxable remuneration such as salary, allowance, commission and bonus.
Annualise the income based on current and expected salary for the tax year.
Deduct eligible items such as EPF and reliefs that have been declared or keyed into payroll.
Apply resident progressive tax rates or non-resident treatment depending on tax residency.
Deduct rebates, zakat or previous PCB paid where relevant to calculate the monthly deduction.
Income Subject to PCB
PCB is not limited to basic salary. The Malaysia Government Portal lists fixed monthly salary, allowances or annual bonuses, and cash-based benefits received as part of income as types of income subject to PCB.
PCB Example: RM5,000 Monthly Salary
The example below uses a single Malaysian tax resident employee under 55 with RM5,000 monthly gross salary, 11% employee EPF and basic personal relief only. This is a planning example, not an official LHDN assessment.
In this example, the estimated PCB is around RM110 per month. The actual monthly PCB may differ if the employee has other reliefs, bonus, zakat, children, spouse details or payroll adjustments.
Why PCB Changes Every Month
PCB may change because it is based on estimated annual tax, not only one fixed monthly salary number. If payroll inputs change, the monthly deduction can also change.
Common Reasons
- Bonus, commission or overtime paid in the month.
- Salary increment, unpaid leave or backdated salary.
- Updated marital status, children or spouse details.
- New relief, zakat or TP1 information entered into payroll.
Payroll Reasons
- Previous month PCB adjustment.
- CP38 additional tax deduction instruction.
- Resident or non-resident status update.
- Incorrect employee profile later corrected by payroll.
TP1, TP3 and CP38: Forms Employees Should Know
Some PCB-related forms affect how payroll calculates monthly deductions. Employees do not need to memorise every tax form, but these three are useful to understand.
PCB for Resident and Non-Resident Employees
PCB calculation depends heavily on tax residency. A Malaysian tax resident may be taxed using progressive rates and eligible reliefs. A non-resident employee may be subject to a flat non-resident tax rate on Malaysian employment income.
LHDN states that a person is non-resident if they stay in Malaysia for less than 182 days in a year, regardless of citizenship or nationality. Foreign employees and employees with cross-border work should pay close attention to this setting.
Is PCB Final Tax?
PCB is usually a monthly tax instalment, not automatically the final tax. At year-end, your actual tax is calculated through the annual income tax return after all income, reliefs, rebates and PCB payments are considered.
Malaysia also has rules where MTD may be treated as final tax in certain situations, but employees should not assume this applies automatically. If you have other income, relief claims, job changes, incorrect payroll details, or special tax circumstances, you should review your filing position carefully.
Employer Responsibility and PCB Payment Deadline
Employers are responsible for deducting PCB from employee remuneration and remitting it to LHDN. Competitor payroll guides and LHDN-related references commonly note that PCB should be submitted monthly, usually by the 15th day of the following month.
Employees should check their payslip and EA Form. If PCB is deducted from salary but does not appear correctly in tax records, ask payroll for confirmation and keep supporting documents.
PCB vs EPF, SOCSO and EIS
PCB is often shown together with EPF, SOCSO and EIS on a payslip, but it is different. EPF is retirement savings, SOCSO is social security protection, EIS is employment insurance, and PCB is income tax deducted monthly.
How to Check Your PCB
Employees should check PCB regularly, especially after bonus months, salary changes or job changes. A simple check can help you catch payroll profile errors early.
Check the PCB or MTD line on your monthly payslip.
Compare the annual PCB total with your EA Form and tax records.
Use a PCB calculator to estimate whether the amount looks reasonable.
Ask payroll if marital status, children, TP1, TP3 or previous PCB information may be missing.
Frequently Asked Questions About PCB Tax
What is PCB tax in Malaysia?
PCB is Malaysia's Monthly Tax Deduction system. It is the estimated income tax deducted from employee salary every month and remitted to LHDN by the employer.
Is PCB the same as MTD?
Yes. PCB means Potongan Cukai Bulanan, while MTD means Monthly Tax Deduction. They refer to the same monthly payroll tax deduction system.
Is PCB deducted from gross salary?
Yes. PCB is deducted from salary through payroll, after payroll calculates the estimated tax deduction based on income and employee tax information.
Does PCB mean I do not need to file income tax?
No. PCB helps pay tax monthly, but employees may still need to file an annual tax return and confirm whether their final tax is fully paid, overpaid or underpaid.
Why is PCB higher in a bonus month?
Bonus increases estimated annual taxable income, so the monthly PCB for that month may increase. Payroll systems may treat bonus separately or adjust the remaining annual tax estimate. For a focused estimate, use the Bonus Tax Calculator Malaysia.
What is TP1 for PCB?
TP1 is an employee form used to claim certain deductions and rebates for monthly tax deduction purposes, so payroll can consider eligible information when calculating PCB.
What is CP38?
CP38 is an additional tax deduction instruction from LHDN. If CP38 applies, your monthly deduction may be higher than the normal PCB amount.
