PCB / MTD in Malaysia: How Monthly Tax Deduction Works

Why your employer deducts PCB

Under the Income Tax (Deduction from Remuneration) Rules 1994, every employer must withhold tax from an employee's monthly remuneration and remit it to LHDN by the 15th of the following month. The idea is pay-as-you-earn: instead of a large tax bill after filing, your tax is spread across twelve payslips. If PCB was deducted correctly all year, your final tax at filing is close to zero.

PCB applies to salary, wages, allowances, commissions, bonuses, director's fees and most cash remuneration. It does not apply to statutory contributions your employer pays (EPF, SOCSO, EIS) or to benefits that are not cash remuneration in the ordinary sense.

How the monthly amount is calculated

There are two official routes. Most payroll software uses the Computerised Calculation Method: it annualises your expected income for the year, subtracts the reliefs it knows about, computes the tax on that chargeable income using the resident brackets, applies rebates, and then spreads the balance over the remaining months of the year. The alternative is the MTD Schedule (Jadual PCB) — LHDN's lookup tables that give a deduction for each wage band and category.

By default PCB builds in the individual relief (RM9,000), the EPF/approved-scheme relief capped at RM4,000 a year, and the category (single, married with non-working spouse, number of children). It does not automatically know about your other reliefs — insurance, lifestyle, medical, education — unless you tell your employer.

TP1, TP2 and TP3 — telling PCB about your reliefs

Three forms let you sharpen your PCB so it matches your real tax:

• TP1 — you declare additional reliefs and rebates (lifestyle, medical, education, insurance, zakat) during the year so PCB is reduced accordingly instead of you waiting for a refund at filing.
• TP2 — used to include benefits-in-kind and value of living accommodation (perquisites) in the PCB base.
• TP3 — you give a new employer your accumulated income and PCB from a previous employer in the same year, so mid-year job changes are taxed correctly.

When PCB is your final tax (no need to file)

Under Section 77C of the Income Tax Act 1967 you can elect for PCB to be your final tax and skip filing an income tax return, if you meet all the conditions: you have employment income only (no rental, business or other income), you were employed by the same employer for the full 12 months of the basis year, your PCB was deducted correctly, you are not opting for joint assessment with your spouse, and your employer has not borne your tax. If any condition fails — you changed jobs, earned side income, or want to claim reliefs you did not declare via TP1 — you should still file to reconcile.

Bonuses and one-off payments

A bonus or backpay is 'additional remuneration' and is not simply added to that month's salary at the normal rate. PCB rules compute the tax on your normal pay for the year, then the tax on your pay plus the bonus, and deduct the difference in the bonus month. The effect is that the payslip month containing a bonus shows a noticeably larger PCB — which is why a steady-state estimate never matches a bonus month.

Worked example

Take an employee earning RM5,000 a month (RM60,000 a year) with the standard 11% EPF and no dependants. Annual EPF is RM6,600, but the relief is capped at RM4,000. Chargeable income is RM60,000 − RM9,000 (self) − RM4,000 (EPF cap) = RM47,000.

Tax on RM47,000 comes to about RM1,320 (RM150 on the 1% band, RM450 on the 3% band, and 6% on the RM12,000 above RM35,000). There is no RM400 rebate because chargeable income exceeds RM35,000. Spread over 12 months that is roughly RM110 of PCB a month. LHDN's official schedule uses a built-in monthly rebate and stepped tables, so your real payslip PCB will differ by a few ringgit — declaring extra reliefs via TP1 lowers it further.

Important caveats

This is a planning explanation and estimate only. The actual PCB on your payslip comes from LHDN's official MTD calculation, which factors in your marital and child category, TP1/TP2/TP3 declarations, and a monthly rebate mechanism this simplified view does not model. Rates, reliefs and the deduction rules are set by law and revised at each budget.
