What Is PCB?

PCB stands for Potongan Cukai Bulanan, or Monthly Tax Deduction (MTD). It is a system where employers deduct estimated income tax from employees' remuneration and remit the amount to HASiL on behalf of the employee.

PCB helps spread income tax payments across the year instead of requiring the employee to settle the whole tax amount only after annual filing.

Who May Have PCB Deducted?

PCB generally arises when an employee's estimated tax position produces a monthly tax deduction under the official MTD calculation method. Not every employee will necessarily have PCB deducted.

For employees with lower taxable income, the calculated PCB may be nil after considering the applicable tax treatment, deductions and relief information used in payroll. This is why an employee can still have EPF, SOCSO and EIS deductions while having no PCB for a particular month.

Important: PCB should be determined using HASiL's approved computerized calculation method or e-Jadual PCB through e-CP39, not by applying a simple flat percentage to monthly salary.

How PCB Works in Malaysia

PCB is calculated from payroll information and is designed to estimate the employee's income tax position progressively during the year.

FactorHow It Affects PCB
Monthly RemunerationHigher taxable remuneration generally increases the estimated annual tax and monthly PCB.
Accumulated RemunerationYear-to-date income is relevant because PCB uses cumulative information in computerized calculation.
EPF ContributionEligible EPF deductions are taken into account subject to the applicable PCB calculation rules and limits.
Tax Deductions / RebatesApproved deductions and rebates reflected through payroll may reduce PCB.
Bonus / Additional RemunerationAdditional remuneration is calculated separately under the PCB computerized method and can cause a higher deduction in that month.
Tax Residency / Special Tax TreatmentThe applicable tax treatment can materially change the monthly deduction.
Key point: PCB is a payroll mechanism for income tax. It is not the same type of statutory contribution as EPF, SOCSO or EIS.

How PCB Is Calculated

PCB is calculated using HASiL's Monthly Tax Deduction rules and 2026 computerized calculation specification. The calculation considers normal remuneration, accumulated remuneration and deductions, accumulated PCB, applicable relief information and tax rates.

Additional remuneration such as bonus is handled using a specific additional-remuneration calculation rather than simply dividing estimated annual tax by 12.

PCB ≠ Monthly Salary × Fixed Tax Rate Actual PCB follows HASiL's MTD calculation method using current-year payroll and tax information.

Simple PCB Example: RM5,000 Monthly Salary

A RM5,000 monthly salary does not automatically produce one universal PCB amount because the deduction can differ according to the employee's tax profile and payroll information.

Monthly salaryRM5,000
Annualised employment incomeUsed as part of the tax estimation
EPF / eligible deductionsConsidered under the applicable PCB rules
Personal / family informationMay affect allowable deductions and rebates
Final monthly PCBDetermined using HASiL's approved calculation method
Why no single RM amount here? Two employees earning RM5,000 can legitimately have different PCB amounts because their accumulated income, deductions, rebates, marital or child information, previous employment data and additional remuneration may differ.

What Can Increase or Reduce PCB?

Your PCB amount can change when your income or tax information changes. This is why PCB may be different from one month to another.

📈

Higher Income

Salary increments and additional taxable remuneration can increase PCB.

🎁

Bonus & Commission

Additional remuneration may trigger a higher PCB deduction in the payment month.

💸

Deductions & Reliefs

Eligible items reflected correctly for PCB purposes may reduce the deduction.

👨‍👩‍👧

Personal Information

Relevant spouse, child and other tax information may affect the calculation where applicable.

PCB for Bonus, Commission and Additional Remuneration

Bonus, commission and other additional remuneration can increase PCB because they increase taxable employment income. Under HASiL's computerized method, additional remuneration has a specific calculation procedure.

This is why an employee may see a much higher PCB deduction in a bonus month even though the normal monthly PCB is relatively low.

Practical payslip check: When reviewing a bonus month, separate the gross bonus from EPF, SOCSO, EIS and PCB rather than assuming the entire increase in deductions comes from one item.

Tax Reliefs, Deductions and Form TP1

Eligible deductions and rebates can affect PCB when they are properly declared and processed under the applicable HASiL rules. Form TP1 is used by employees to claim qualifying deductions and rebates for Monthly Tax Deduction purposes.

If an employee had previous employment during the same year, Form TP3 is used to provide the new employer with accumulated remuneration, EPF, zakat and PCB information from previous employment so that the current-year PCB calculation can take that information into account.

FormMain Purpose
TP1Employee claim for qualifying individual deductions and rebates for PCB purposes.
TP3Current-year previous-employment information used for PCB calculation by the new employer.

PCB vs Annual Income Tax

PCB is not a separate tax. It is a monthly payment toward the employee's income tax position.

ItemMeaning
PCB / MTDMonthly income tax deduction through payroll.
Income Tax ReturnAnnual declaration of income, deductions, reliefs and final tax position where filing is required.
Tax RefundMay arise when tax paid or deducted exceeds the final tax liability.
Additional Tax PayableMay arise when total tax paid or deducted is lower than the final tax liability.
Important: In certain circumstances, eligible taxpayers may treat PCB as final tax and may not need to submit an income tax return, but only when all conditions prescribed by HASiL are satisfied.

PCB vs EPF, SOCSO and EIS

EPF, SOCSO and EIS are statutory payroll contributions or social protection deductions, while PCB is a monthly income tax deduction. All can affect take-home pay, but they serve different purposes.

DeductionMain PurposeEmployee Take-Home Pay?
EPFRetirement savingsReduced by employee contribution
SOCSOSocial security protectionReduced by employee contribution
EISEmployment insuranceReduced by employee contribution
PCBMonthly income tax paymentReduced by PCB deducted

Why PCB Can Change From Month to Month

PCB can change when salary changes, a bonus or commission is paid, previous-employment information is added, tax deduction information is updated or payroll has additional remuneration to process.

A higher PCB in one month does not automatically mean the payroll calculation is wrong. The correct amount depends on the employee's accumulated current-year tax position and the applicable MTD calculation rules.

PCB, Tax Refund and Additional Tax Payable

After the relevant year ends, the taxpayer's final tax position can be compared with tax already paid through PCB.

SituationPossible Result
Total tax paid through PCB is higher than final tax liabilityA tax refund may arise.
Total PCB is lower than final tax liabilityAdditional tax may need to be paid.
Total PCB broadly matches final tax liabilityThere may be little or no remaining balance.

PCB Payment Deadline for Employers

Employers must deduct PCB from employee remuneration and remit the PCB to HASiL on or before the 15th day of the following month.

Deduction MonthPayment Deadline
January 2026On or before 15 February 2026
February 2026On or before 15 March 2026
Submission Channels

HASiL provides e-PCB, e-Data PCB and e-CP39 through MyTax / ezHasil for PCB submission.

Employer Responsibilities
  • Calculate PCB using an approved method
  • Deduct the correct amount from remuneration
  • Submit employee PCB data
  • Remit payment by the deadline

Common PCB Payroll Mistakes

  • Assuming PCB is a fixed percentage of monthly salary.
  • Ignoring previous-employment information during the same calendar year.
  • Forgetting that bonus and other additional remuneration require specific PCB treatment.
  • Using outdated employee deduction or rebate information.
  • Confusing PCB with EPF, SOCSO or EIS.
  • Assuming PCB deducted each month will always equal the employee's final annual tax liability.
