CP39A Form — PCB Supplementary Schedule (Malaysia)

A CP39A Form — PCB Supplementary Schedule in Malaysia records the information the relevant body requires to process the matter.

Under Rule 11 of the PCB Rules 1994, when an employer makes a supplementary or additional payment to an employee, the standard monthly PCB calculation table (CP39) does not automatically account for the tax effect of such payments. The CP39A provides the mechanism for employers to correctly spread the additional remuneration across the remaining months of the tax year or to compute a one-off additional PCB deduction, confirming the employee's tax account accurately reflects total year-to-date income.

The CP39A form is used alongside the primary CP39 PCB computation table. LHDN publishes updated PCB computation tables annually through Public Ruling No. 1/2024 and the e-PCB system on the ezHasil portal, which allows employers to compute CP39A supplementary deductions electronically without manual calculation.

Employers who fail to correctly compute and deduct PCB on supplementary payments face liability under Section 107 of the Income Tax Act 1967, which makes the employer personally responsible for any shortfall in PCB that should have been deducted from the employee's income. Underpayment of PCB identified during LHDN's employer audit process — conducted under the LHDN Audit Framework 2022 — may result in penalty assessments on the employer under Section 113 of the ITA 1967.

The legal framework governing the CP39A Form — PCB Supplementary Schedule (Malaysia) in Malaysia draws on several key statutes and regulatory bodies. Under Malaysian law, the Contracts Act 1950 (Act 136) governs contractual obligations. The Companies Act 2016 (Act 777) regulates corporate entities through the Companies Commission of Malaysia (SSM). The Employment Act 1955 (Act 265) and the Department of Labour govern employment matters. The Personal Data Protection Act 2010 (Act 709) and the Personal Data Protection Department protect personal data. The Inland Revenue Board of Malaysia (LHDN) administers tax obligations. The Industrial Court adjudicates employment disputes under the Industrial Relations Act 1967 (Act 177). Parties executing a CP39A Form — PCB Supplementary Schedule (Malaysia) in Malaysia should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Employment Act 1955 (Act 265) sets the foundational requirements.

A CP39A form is required in Malaysia whenever an employer makes a supplementary or additional remuneration payment to an employee that is not part of the regular monthly salary, requiring a separate PCB computation under Rule 11 of the Income Tax (Deduction from Remuneration) Rules 1994.

A CP39A is needed when an employer pays an annual bonus or performance incentive bonus at any point during the tax year. The bonus amount must be incorporated into the employee's annualised income to determine the correct marginal tax rate, and the CP39A provides the computation method for the additional PCB deduction on the bonus payment.

A CP39A form is required when an employer pays salary arrears — for example, backpay following a salary review or an Industrial Court award. Arrears payments represent income that should have been taxed in earlier months and require separate PCB computation to avoid under-deduction.

A CP39A is needed when an employer pays a commission lump sum or incentive payment that is not part of the standard monthly salary. Sales-based companies paying quarterly or half-yearly commissions to employees must use CP39A to calculate the additional PCB on each commission payment.

A CP39A form is required when an employer pays gratuity or ex-gratia payments that are taxable under Section 13 of the Income Tax Act 1967. Not all gratuity payments are exempt — only those meeting specific conditions under Schedule 6 of the ITA 1967 escape PCB deduction.

A CP39A is needed when an employer adjusts an employee's salary mid-year with retrospective effect, creating a difference between PCB already deducted at the old salary rate and the PCB properly due on the revised salary inclusive of arrears.

Parties in Malaysia should prepare a CP39A Form — PCB Supplementary Schedule (Malaysia) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under Malaysian law, the Contracts Act 1950 (Act 136) governs contractual obligations. The Companies Act 2016 (Act 777) regulates corporate entities through the Companies Commission of Malaysia (SSM). The Employment Act 1955 (Act 265) and the Department of Labour govern employment matters. The Personal Data Protection Act 2010 (Act 709) and the Personal Data Protection Department protect personal data. The Inland Revenue Board of Malaysia (LHDN) administers tax obligations. The Industrial Court adjudicates employment disputes under the Industrial Relations Act 1967 (Act 177). Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A complete CP39A supplementary PCB schedule for Malaysia must include the following elements as required by LHDN under the Income Tax (Deduction from Remuneration) Rules 1994.

Employee identification: Full name, NRIC or passport number, and income tax reference number (SG or OG prefix) matching the employee's registration with LHDN. The employer's E number and PCB account reference are also required to link the supplementary schedule to the correct employer account in the ezHasil system.

Regular monthly remuneration: The employee's gross monthly salary for the current month, including all regular allowances and benefits assessed under Section 13 of the Income Tax Act 1967. This baseline figure is needed to compute the annualised income that incorporates the additional payment.

Additional remuneration details: The nature of the additional payment (bonus, arrears, commission, gratuity, or other lump sum), the amount in Malaysian Ringgit (RM), and the period to which the payment relates. Where the payment relates to prior months, specifying the accrual period allows LHDN to assess whether the PCB computation method applied is correct.

PCB computation: The step-by-step computation of the additional PCB deduction, following the method prescribed in the current year's LHDN PCB computation guide. The computation annualises the total remuneration (regular monthly salary multiplied by 12, plus additional payment), determines the annual tax liability based on the tax rates in Schedule 1 of the Income Tax Act 1967, and deducts already-deducted PCB to arrive at the additional PCB amount due.

Personal reliefs and deductions: Employee personal reliefs applicable under Sections 45 to 49 of the ITA 1967 — including spouse relief (RM 4,000), child relief (RM 2,000 per child), and EPF contribution relief (up to RM 4,000) — which reduce the taxable income base for PCB computation. Employers should use the relief information declared by the employee on Form TP1.

Total PCB remittance: The total additional PCB amount to be remitted to LHDN in the current month, combining regular PCB and the supplementary CP39A amount. Remittance must be made by the 15th of the following month through the LHDN e-PCB portal under Rule 3(3) of the PCB Rules 1994.
