Section 6 -- Worked Examples
Example 1 -- Sole Proprietor CP500
Situation: Graphic designer, YA 2024 tax liability was RM8,400. LHDN issues CP500 for YA 2025 based on this amount.
CP500 schedule: 6 × RM1,400 = RM8,400 total
- 15 Mar: RM1,400
- 15 May: RM1,400
- 15 Jul: RM1,400
- 15 Sep: RM1,400
- 15 Nov: RM1,400
- 15 Jan 2026: RM1,400
Actual YA 2025 tax liability: RM10,200. Balance of RM1,800 due upon filing Form B (30 June 2026).
Example 2 -- CP500 Revision
Situation: Consultant expects income to drop significantly. Revised estimate: RM4,500 tax for the year.
Action: Submits Form CP502 by 30 June 2025. Remaining 3 instalments reduced. Already paid RM4,200 (3 × RM1,400). New instalments: RM100 each for Jul, Sep, Nov.
Risk: If actual tax turns out to be RM7,000, difference from revised estimate (RM7,000 - RM4,500 = RM2,500) is >30% of actual (30% × RM7,000 = RM2,100). Since RM2,500 > RM2,100, a 10% penalty on RM2,500 = RM250 may apply.
Section 7 -- Interaction with Other Systems
| System |
Interaction |
| Form B filing |
CP500 paid is credited against final tax liability on Form B |
| EPF/SOCSO/EIS |
See my-epf-socso skill; these are separate from income tax instalments |

Tax withheld by payer on certain payments is also credited against final tax |

Prohibitions

- NEVER advise skipping CP500 payments -- 10% penalty applies immediately
- NEVER revise CP500 below 70% of expected actual tax without warning about underestimation penalty
- NEVER submit Form CP502 after 30 June of the assessment year
- NEVER assume first-year businesses will automatically receive CP500 -- they may need to register
- NEVER present calculations as definitive -- always label as estimated
