PCB versus annual income tax at a glance
| Aspect | PCB (Monthly Tax Deduction) | Annual income tax |
|---|---|---|
| Timing | Deducted every month from salary. | Assessed once for the whole year. |
| Purpose | A tax instalment — a prepayment spread across the year. | Your final tax liability for the year of assessment. |
| Who deducts or reports it | Your employer deducts and remits it to HASiL. | You report and confirm it yourself at e-Filing. |
| When it is finalised | Recalculated on each payslip through the year. | Finalised after your assessment is submitted. |
PCB as monthly tax instalments through payroll
PCB is deducted by your employer each month and paid to HASiL on your behalf. Rather than facing one large tax bill at the end of the year, you settle your tax gradually as you earn. The monthly amount is worked out from your annualised taxable income, EPF, reliefs, rebates and year-to-date records, so it can move from month to month — a bonus month, for example, often carries a higher deduction.
Because it is an instalment, PCB is an estimate of your tax collected in advance. It is designed to track your likely annual tax closely, but it is not the same thing as the final figure your assessment confirms.
Annual tax liability through e-Filing
Income tax is the total you actually owe for a year of assessment. When you complete e-Filing, your full-year income, all eligible reliefs and rebates, and any income outside your main salary are brought together to arrive at the final liability. This is where the year is settled properly, not just estimated month by month.
Filing matters because your final tax can differ from the total PCB deducted. Reliefs you did not claim through payroll, additional income, or a change of employer during the year can all move the final figure away from the running total your payslips showed.

When PCB paid may be higher or lower than final tax
Total PCB for the year and your final assessed tax are two different numbers, and they will not always match. PCB is calculated from the information available to payroll during the year; your assessment uses the complete, confirmed picture. The gap between them can go either direction.
- Reliefs claimed at filing but not through payroll can make your final tax lower than the PCB already deducted.
- Extra taxable income not captured in payroll can make your final tax higher than the PCB deducted.
- Changing jobs, or PCB not reflecting your full circumstances, can push the two figures apart in either direction.
Refunds and balances payable
When your total PCB for the year is more than your final assessed tax, the difference may be refunded to you. When it is less, you may have a balance to pay after filing. Which one applies depends entirely on how your PCB compares with your final liability, so neither outcome is guaranteed in advance.
Treat any refund as possible rather than certain, and any balance payable as something to check for once your assessment is finalised. The reliable way to know is to file and let the assessment reconcile the two figures.
When PCB can count as final tax
In some cases, PCB may be treated as final tax, which can mean an eligible employee is not required to file separately. This is not automatic and does not apply to everyone — it depends on the official conditions set by HASiL, which cover matters such as having income from a single employer and correctly deducted PCB.
Because these conditions are specific and can change, do not assume PCB is your final tax. Confirm your eligibility against the official references in the sources panel on this page before relying on it.
How to actually declare your income for tax purposes
Declaring income tax in Malaysia means completing e-Filing for the year of assessment, using the return form that matches the kind of income you have, then submitting it through HASiL's MyTax portal. The steps are the same whether your income is a single salary, several income sources, or income that changes month to month.
1. Make sure you can log in first. You need a Tax Identification Number (TIN) and active e-Filing access before you can declare anything. Many people already have a TIN without realising it, so check with e-Daftar before assuming you need to register from scratch — see DuitMap's guide to checking and registering for a TIN for the correct order to do this in.
2. Use the return form that matches your income. HASiL's individual e-Filing forms are split by income type, not by how many payslips you have. If every ringgit you earned in the year came from an employer, one form generally applies; if you also had, or only had, business, freelance or gig income, a different form generally applies instead — DuitMap's Borang BE guide and Borang B guide set out exactly which one fits your situation and what LHDN treats as business income for this purpose.
3. Declare everything together, not per source. Your chargeable income for the year is worked out from all your income combined — employment plus any business, freelance, gig-platform, rental or other income — inside the one return, not as separate filings per employer or per platform.
For exactly which supporting documents to keep before you sit down to file — payslips, the EA form from an employer, receipts for reliefs you plan to claim — see DuitMap's record-keeping checklist for e-Filing.
Declaring gig or irregular income
If part or all of your income does not come from one steady employer — freelance projects, e-hailing or delivery platform work, or a side business with income that moves month to month — HASiL still expects it to be declared. It does not automatically count as ordinary employment income for e-Filing purposes, and it is usually treated as business income instead. DuitMap's gig income tax overview walks through this in more detail.
Registering with SSM and declaring to LHDN are two different obligations. Under the Registration of Businesses Act 1956 [Act 197] — administered by the Companies Commission of Malaysia (SSM) — an activity that meets the Act's definition of a "business" must generally be registered with SSM within thirty days of starting, subject to a small number of exemptions in the Act's Schedule (checked against SSM's own reprint of Act 197, 18 August 2026). Whether or not that registration has been done, the income itself is still taxable and still has to be declared to LHDN — one obligation does not excuse the other. See DuitMap's guide to freelancers and SSM registration for who is actually covered by the exemptions.
"Gig worker" and "business income" are also two different questions. Malaysia's Gig Workers Act 2025 [Act 872] received royal assent on 16 December 2025 and was gazetted on 31 December 2025; its provisions come into force on dates the Minister sets separately by notification in the Gazette. That Act governs the working relationship between a gig worker and a platform — it is a labour-protection classification, not a tax rule — so being (or not being) a "gig worker" under Act 872 has no bearing on whether income from that work must be declared to LHDN.
What you can claim against gig or freelance income. Once income is declared as business income, expenses can only reduce your taxable amount if they meet the Income Tax Act 1967's own test: under section 33(1), an expense must be incurred wholly and exclusively in producing that income, and section 39(1) then blocks common claims such as private or domestic expenses and capital spending (a laptop or a vehicle, for instance, is generally handled separately through capital allowances rather than claimed outright). DuitMap's deductible business expenses checklist runs through what typically passes this test and what typically does not.
Because gig or freelance income usually has no PCB deducted from it as you go, the amount owed at filing time can come as a larger single figure than it would for a salaried employee. Keeping your own running records through the year — rather than reconstructing them at filing time — is what makes that figure predictable instead of a surprise.
