Everything employers and employees need to know about potongan cukai bulanan — from the official LHDN formula to step-by-step MTD examples and a free interactive PCB calculator Malaysia tool.
If you run payroll in Malaysia, a PCB calculator Malaysia tool is one of the most important compliance resources you’ll use every month. Employers must deduct the correct Potongan Cukai Bulanan (PCB) amount from employee salaries and remit it to LHDN before the 15th of the following month. Using an accurate PCB calculator Malaysia 2026 estimate helps reduce payroll errors, underpayments, and compliance penalties that can reach up to 35% of unpaid tax.
This guide explains how the PCB calculator Malaysia system works, how Monthly Tax Deduction (MTD) is calculated, which tax reliefs reduce PCB deductions, and how employers can automate payroll compliance. You’ll also find a free PCB calculator Malaysia 2026 estimator below to calculate your monthly PCB instantly.
What Is PCB (Potongan Cukai Bulanan)?
Quick Answer: PCB (Potongan Cukai Bulanan) and MTD (Monthly Tax Deduction) are the same thing — Malaysia’s pay-as-you-earn income tax system where employers deduct tax monthly on behalf of LHDN. The deduction is not a separate tax; it is a prepayment of your annual income tax, spread over 12 months.
PCB stands for Potongan Cukai Bulanan, the Bahasa Malaysia term for Monthly Tax Deduction. In English-facing contexts, it is also called MTD (Monthly Tax Deduction). Both terms appear on your payslip and in LHDN correspondence — they mean exactly the same thing.
The system was introduced under the Income Tax Act 1967 to spread employees’ tax obligations across the year rather than requiring a single large payment at filing time. Your employer calculates the expected PCB each month, deducts it from your gross salary, and remits it to LHDN using Form CP39 by the 15th of the following month in accordance with LHDN PCB employer requirements.
PCB is not a new tax. Think of it as a 12-month installment plan for your annual income tax bill. When you file your return (Form BE, due by 30 April), LHDN reconciles the total PCB deducted against your actual tax liability. If too much was deducted, you receive a refund — typically within 30 to 90 days.
Key point for employers: Late or incorrect PCB submissions attract stiff penalties. Automate your potongan cukai bulanan calculations with payroll software to eliminate manual risk and ensure every submission hits the 15th-of-month deadline without fail.
Malaysia 2026 Progressive Tax Brackets
The PCB calculator Malaysia 2026 formula uses Malaysia’s progressive income tax structure. Higher income levels are taxed at higher marginal rates.
| Annual Chargeable Income (RM) | Tax Rate | Tax on This Band |
|---|---|---|
| First RM5,000 | 0% | RM0 |
| RM5,001 – RM20,000 | 1% | Up to RM150 |
| RM20,001 – RM35,000 | 3% | Up to RM450 |
| RM35,001 – RM50,000 | 6% | Up to RM900 |
| RM50,001 – RM70,000 | 11% | Up to RM2,200 |
| RM70,001 – RM100,000 | 19% | Up to RM5,700 |
| RM100,001 – RM400,000 | 25% | Up to RM75,000 |
| RM400,001 – RM600,000 | 26% | Up to RM52,000 |
| RM600,001 – RM2,000,000 | 28% | Up to RM392,000 |
| Above RM2,000,000 | 30% | On excess |
A PCB calculator Malaysia for non-residents works differently because non-resident employees are taxed at a flat 30% rate without personal tax reliefs.
Key Tax Reliefs That Reduce Your PCB in 2026
Tax reliefs reduce your chargeable income before the progressive rates are applied, which directly lowers your monthly PCB deduction. Employees declare their reliefs to their employer via the TP1 form, allowing the employer to adjust monthly PCB accordingly — improving monthly cash flow instead of waiting for a year-end refund.
The most commonly applied reliefs for YA 2025/2026 are:
Personal Relief
RM9,000
Automatic for every resident individual
Spouse Relief
RM4,000
If spouse has no income
EPF Contributions
Up to RM4,000
Employee contribution (11% standard)
Child Relief
RM2,000–RM8,000
Per child, varies by age and education
Life Insurance & Takaful
Up to RM3,000
Premiums for life insurance or takaful policies
Medical & Education Insurance
Up to RM4,000
Combined cap for medical and education insurance premiums
SOCSO & EIS
Up to RM350
Combined employee contributions
Lifestyle
Up to RM2,500
Books, internet, electronics, sports
SSPN Education Savings
Up to RM8,000
Net savings in the year
In addition, employees with an annual chargeable income below RM35,000 receive a RM400 individual tax rebate (applied after tax is calculated, not before). Married individuals may qualify for an additional RM400 spouse rebate, if the husband or wife does not have any chargeable income.
The reliefs listed above are among the most commonly claimed, but there are many more available — including medical expenses for serious diseases, parental care, education fees, PRS contributions, and more.

Employer tip: The official LHDN calculators are suitable for spot-checking individual employee deductions. For bulk payroll processing across many employees, use a compliant payroll system like QNE Cloud Payroll that auto-generates CP39 batch files and applies all statutory rates in one run.
How the PCB Formula Works: The Official LHDN Method
LHDN uses a computerised calculation method for employers running payroll software. The core logic is straightforward: project your annual income tax, subtract what has already been collected year-to-date, then divide the remainder equally across the remaining months in the year.
The key formula components are:
- P = Annual chargeable income (gross annual salary minus EPF minus tax reliefs)
- PR = Annual tax on P using the progressive bracket table
- T = PCB already deducted in previous months of the current year
- Z = Zakat already paid in previous months
- X = Tax rebate (RM400 if P ≤ RM35,000)
- n = Remaining months after the current month
Monthly PCB = (PR – T – Z – X) ÷ (n + 1)
This is why a mid-year pay rise or bonus can cause a sudden spike in PCB. When annual projected income increases, LHDN recalculates the full-year liability and redistributes the remaining tax burden across fewer months — leading to a noticeably higher deduction for the rest of the year.
This explains why bonuses and salary increments can significantly increase monthly deductions later in the year. A PCB calculator Malaysia automatically recalculates projected annual tax whenever income changes.
Step-by-Step MTD Examples for 2026
Let’s walk through two practical examples to see how the PCB calculator Malaysia 2026 logic applies in real payroll scenarios.
Example 1: Single employee, RM5,000/month, standard EPF 11%
RM15,000 × 1% = RM150
RM15,000 × 3% = RM450
RM12,000 × 6% = RM720
Annual tax = RM1,320
6. Divide by 12: RM1,320 ÷ 12 = RM110/month
Estimated monthly PCB for this employee: RM110
Example 2: Married employee, RM10,000/month, spouse no income, 2 children
RM5,000 × 0% = RM0 RM15,000 × 1% = RM150 RM15,000 × 3% = RM450 RM15,000 × 6% = RM900 RM20,000 × 11% = RM2,200 RM29,000 × 19% = RM5,510 Annual tax = RM9,210
Tip: The employee in Example 2 could further reduce their PCB by submitting a TP1 form declaring additional eligible reliefs such as medical insurance premiums, education fees, or SSPN contributions — potentially saving hundreds of ringgit per month in deductions.
How to Reduce Your PCB Legally Using the TP1 Form
Many employees overpay PCB simply because they don’t declare their full entitlements to their employer. The TP1 form is the official LHDN mechanism for employees to declare their eligible reliefs, so that employers can calculate a lower — and more accurate — monthly PCB deduction.
Reliefs that can be declared via TP1 include voluntary EPF contributions, life insurance and takaful premiums, spouse and child reliefs, SSPN savings, medical insurance, and more. Submitting TP1 at the start of the year (or whenever your circumstances change) is the most effective way to improve monthly cash flow without waiting for a lump-sum annual refund.
A separate TP3 form is used when an employee has changed jobs during the year, to declare PCB already paid under a previous employer so the new employer doesn’t double-count deductions.
Employer Obligations: The 15th-of-Month Deadline
Under the Income Tax Act 1967, employers must remit PCB to LHDN by the 15th of the following month. For example, January’s payroll PCB must be submitted by 15 February. Submissions are made electronically through LHDN’s e-PCB system or ezHasil, using Form CP39 or the CP39A batch format for larger payrolls.
Failure to remit on time, or submitting incorrect amounts, can attract penalties of up to 35% of unpaid tax — plus potential legal action under the Act. For SMEs processing payroll manually, this creates significant compliance risk every single month.

At what salary does PCB kick in?
For a single Malaysian tax resident with standard EPF 11% contribution and no additional reliefs beyond the default personal relief of RM9,000, PCB deductions typically begin when monthly salary exceeds approximately RM2,851. Below this threshold, the annual chargeable income remains within the 0% tax bracket. The exact threshold shifts based on marital status, children, and other declared reliefs.
Can I get a refund if too much PCB was deducted?
Yes. If your total PCB deductions for the year exceed your actual tax liability, you are entitled to a refund from LHDN. You claim this when filing your annual income tax return (Form BE, due 30 April). To avoid overpayment in the first place, submit accurate TP1 declarations to your employer so that monthly PCB reflects your full relief entitlements. LHDN typically processes refunds within 30 to 90 days and credits them to your registered bank account.
What is the difference between PCB, MTD, and potongan cukai bulanan?
They are three names for the same thing. PCB (Potongan Cukai Bulanan) is the full Bahasa Malaysia term. MTD (Monthly Tax Deduction) is the English equivalent. Potongan cukai bulanan is the same as PCB — “potongan” means deduction, “cukai” means tax, and “bulanan” means monthly. All three terms appear in official LHDN documents, payslips, and payroll software.
Why did my PCB suddenly increase mid-year?
A mid-year salary increase, bonus, or additional allowance changes your projected annual income. LHDN’s PCB formula recalculates the full-year tax liability and then distributes the remaining balance (after subtracting what has already been deducted) across the remaining months of the year. With fewer months left, each month’s deduction is higher. This is expected behavior — not an error — and resolves at year-end when your actual liability is assessed.
