Malaysia Tax Refund Guide 2026: How to Claim Back Overpaid PCB, Check Refund Status & Avoid Excess Deductions

A Malaysian employee in the 8% tax bracket earns RM4,800 a month. Their employer deducts RM120 in PCB each month — RM1,440 over the year. When they file their BE form and compute their actual tax liability, the number comes to RM520 — after factoring in EPF relief, personal relief, lifestyle relief, SSPN deposits, and medical insurance. They have overpaid by RM920. LHDN owes them money.

But the employee does not know this. They do not file because "the company already deducted my tax." The RM920 sits unclaimed. After six years, the right to claim it expires under the limitation period in the Income Tax Act 1967.

PCB (Potongan Cukai Berjadual) is a withholding mechanism, not a final tax bill. It deducts based on your monthly salary, without accounting for most of the tax reliefs you are entitled to. The result is almost always an overpayment — and the only way to get the money back is to file your tax return. This guide explains what triggers PCB overpayment, how to file to claim a refund, how long it takes, and how to adjust your PCB so you are not lending money to LHDN interest-free.

Use the DuitTools PCB calculator to check whether your monthly PCB deduction matches what it should be, and the salary calculator to see your full take-home pay breakdown.

Why PCB Almost Always Over-Deducts

PCB is calculated using the PCB schedule published by LHDN. It is applied to your monthly gross salary — but the schedule is designed to approximate your annual tax liability based on your monthly income alone. It makes assumptions that are conservative (i.e., it over-deducts) in most cases.

The fixed assumptions in the PCB schedule

The PCB formula assumes you receive the same salary every month for 12 months. It assumes you have no tax reliefs beyond the basic personal relief (RM9,000) and EPF contribution relief (RM4,000 cap). Every other relief you claim — medical insurance, education insurance, SSPN deposits, lifestyle purchases, PRS contributions, SOCSO, and any of the 20+ reliefs available — is unknown to the PCB formula.

What the PCB formula does not account for

Your actual tax liability is lower than what PCB projects because of deductions and reliefs the payroll system cannot know about until you report them in your tax return:

An employee who claims only the lifestyle relief (RM2,500) and SSPN relief (RM8,000) reduces their chargeable income by RM10,500. At the 11% marginal rate, that is RM1,155 in overpaid PCB — money that belongs to the employee, not LHDN.

Bonus months inflate PCB disproportionately

When you receive a bonus, your PCB for that month spikes sharply. This is because the PCB calculation for a bonus month treats that month's higher total as if it were your new monthly salary, projecting it across 12 months. The additional tax withheld on the bonus often exceeds the actual marginal tax on that bonus — creating another source of refundable overpayment.

How to File Your Return to Trigger a Tax Refund

The refund is not automatic. LHDN will not compute your refund proactively. You must file your annual tax return — and file correctly.

Step 1: File your BE or B form via myTax

1. Go to https://mytax.hasil.gov.my
2. Log in with your NRIC and password (register if it is your first time — you will need your EA form or previous year's tax number)
3. Select "e-BE" (for employed individuals without business income) or "e-B" (for individuals with business income)
4. The system pre-populates some fields, including your employer-reported income and PCB deducted (from your EA form)
5. Review the pre-populated PCB total against your EA form. Do not skip this — employers make data entry errors and the pre-populated number can be incorrect
6. Enter all applicable tax reliefs
7. The system calculates your tax liability and compares it to your total PCB paid
8. If PCB paid exceeds tax liability, the system displays the refund amount
9. Submit the return

Step 2: Verify your bank account details

LHDN refunds are credited directly into your bank account via EFT (Electronic Funds Transfer). The bank account must:

• Be registered under your NRIC name (the same name as the taxpayer)
• Be a Malaysian bank account (any licensed bank)
• Be active (not dormant or closed)

You can register or update your bank account in the myTax portal under "Perkhidmatan e-Kemaskini" → "e-Permohonan Bayaran Balik."

Step 3: Check refund status

After filing, you can track your refund status:

1. myTax portal: "Semakan Status Bayaran Balik" shows the current stage — "Dalam Proses" (processing), "Diluluskan" (approved), or "Dibayar" (paid)
2. LHDN careline: 1-800-88-5436 (domestic) or +603-8911-1000 (overseas)
3. Hasil Live Chat: Available on the LHDN official portal (https://www.hasil.gov.my) during office hours

How long does the refund take?

E-filed returns are processed faster because the system validates them algorithmically. Paper returns go through manual keying and verification. Refunds for returns filed close to the deadline (April 30 for BE, June 30 for B) take longer because of filing volume.

What delays a refund

• Mismatched details: Bank account name does not match NRIC name
• Desk audit flag: LHDN selects your return for a desk audit (random or risk-based selection). You will receive a letter requesting supporting documents. The refund is held until the audit is cleared
• Employer data mismatch: The PCB amount in your return does not match what your employer reported in Form E
• First-time filer: First-time returns are subject to additional verification
• Large refund relative to income: Refunds exceeding 30% of total tax liability are flagged for review

How to Stop Overpaying PCB in the First Place

Getting a refund is better than not getting one, but lending money to LHDN interest-free for a year is poor cash flow management. The better approach: reduce your monthly PCB so that your deductions more closely match your actual liability.

Request a PCB revision from LHDN

If your PCB is consistently higher than your actual tax liability, you can apply to LHDN for a lower monthly PCB deduction. This is done via:

Form TP1 (PCB revision application):

1. Download Form TP1 from the LHDN website
2. Fill in your estimated annual income, expected reliefs, and expected chargeable income
3. Attach supporting documents (EA form from the previous year, relief receipts, SSPN statement, insurance premium receipts)
4. Submit to your nearest LHDN branch
5. If approved, LHDN issues a PCB deduction instruction to your employer, reducing the monthly PCB to the revised amount

This is under-used. Most employees accept the default PCB deduction and wait for a refund each year. Filing a TP1 converts that annual refund into monthly cash flow — the same total tax paid, but across 12 months at a lower rate instead of as a lump sum deduction.

Claim the PCB rebate of RM400

Low-income employees may qualify for the PCB rebate — a direct RM400 credit against tax payable. If your chargeable income is RM35,000 or below, your tax liability is capped at RM800 (after the standard tax computation). You then subtract the RM400 rebate, leaving a maximum tax of RM400. If PCB deducted exceeds RM400, the balance is refunded.

Many low-income employees who are eligible for this rebate do not claim it because they do not file — "my income is too low to need to file" — and lose the refund.

Frequently Asked Questions

1. Do I need to file a tax return to get my PCB refund?

Yes. Filing is the only mechanism that triggers the refund. LHDN does not automatically reconcile PCB deductions against actual tax liability and issue refunds on its own. No filing = no refund = money stays with LHDN. This is true even if your total income is below the chargeable income threshold (RM37,333 after personal relief) — you should still file to claim the refund of PCB that was deducted.

2. How far back can I claim an overpaid PCB refund?

Under Section 131 of the Income Tax Act 1967, you have six years from the end of the relevant year of assessment to claim a refund. For YA 2020, the deadline is 31 December 2026. If you have unfiled returns from previous years with overpaid PCB, you can still file them and claim the refund, subject to this six-year limit. Late filing penalties may apply, so file voluntarily before LHDN issues a demand notice.

3. Can I transfer my refund to next year's tax liability instead of receiving cash?

Yes. When filing your e-BE or e-B, there is an option to carry forward the credit to the following year of assessment instead of receiving a cash refund. This is rarely the best choice — cash today is worth more than a credit against a future liability. Take the refund and place it in a savings account or SSPN deposit.

4. My employer deducted PCB but I did not receive an EA form. Can I still file and claim a refund?

You can file without the EA form, but LHDN may flag the return for verification if the PCB amount does not match the employer's Form E submission. Contact your employer (or former employer) and request the EA form. Employers are legally required to provide it by 28 February of the following year. If the employer refuses, report it to LHDN — non-issuance of EA forms is an offence under S120(1)(b) of the Income Tax Act.

5. I work two jobs and both employers deducted PCB. Will I get a refund?

Probably not — in fact, you may owe additional tax. Each employer's PCB calculation assumes that salary is your only source of income and applies the progressive tax brackets independently. Your combined income may push you into a higher bracket that neither employer's PCB schedule accounted for. This is one of the few scenarios where PCB under-deducts rather than over-deducts. You must file a return that combines both incomes. The system will calculate the total tax on the combined income and compare it to the sum of PCB from both jobs.

6. What if the refund amount shown in myTax looks wrong?

If the refund looks too high or too low, review:

• Total PCB paid — cross-check with your EA form(s)
• All reliefs entered — a missed relief reduces your refund (because it increases your calculated tax liability)
• Your tax residency status — non-residents are taxed at a flat 30% and are generally not entitled to reliefs
• Any outstanding tax from previous years — LHDN offsets refunds against outstanding tax debts before paying the balance

If the error is on LHDN's side (pre-populated data is incorrect), call the LHDN careline or visit a branch. If the error is on your side, file an amended return before the filing deadline.

PCB is a withholding mechanism, not a tax bill. It is designed to approximate your tax — but because it cannot see your reliefs, it almost always over-estimates. The overpayment is your money, and LHDN will return it — but only if you ask. File your BE or B form every year, claim every relief you are entitled to, check your refund status, and if your PCB consistently over-deducts, file a TP1 to reduce your monthly deductions so the money stays with you throughout the year.

Enter your salary into the DuitTools PCB calculator to see your expected monthly PCB and compare it against your payslip. If you are overpaying, file early and get your money back.
