If you receive a CP500 notice, don’t panic. This notice is an advance tax instalment system from the Inland Revenue Board (LHDN/IRBM). It asks individuals with non-employment income to spread payments across the year. That helps avoid a large lump sum when you file your tax return.
In 2026, LHDN introduced a penalty waiver for missed instalments to ease the transition. Still, understanding the system, the correct form to revise your estimated amount, and the payment schedule is key to staying in compliance.
Compare this to PCB deductions: PCB applies to employment income, while the CP500 system covers other income types. Keep track of amounts and payment time to avoid surprises when you prepare your income tax return.
Key Takeaways
- The CP500 is a bimonthly advance payment system for individuals with non-employment income.
- The 2026 penalty waiver offers temporary relief for missed instalments.
- Use the official form to revise estimated amounts and avoid future shortfalls.
- CP500 differs from PCB; both affect your income tax and filing strategy.
- Stay updated on e-invoice rules and keep records to ensure compliance.
Understanding the CP500 Malaysia Tax System
The CP500 notice is an official bimonthly advance instalment system issued by the Inland Revenue Board to help taxpayers manage non-employment income tax.
The scheme asks each taxpayer who receives the notice to make six payments in a calendar year. These instalments spread your estimated income tax liability so you avoid a single large bill when you file.
Keep in mind: the notice is an estimate based on prior-year earnings, not a final assessment. That means amounts may change when you submit your return.
- Structured collection: six bimonthly payments to smooth cash flow.
- Estimate-based: calculations often use last year’s income as a guide.
- Different from payroll deductions: it covers non-employment income only.
If you’re unsure about dates or amounts, verify your instalment schedule through the official LHDN portal at hasil.gov.my and keep clear records to stay compliant.
Who Receives an Advance Tax Notice
If you earn money outside a regular payroll, the Inland Revenue Board may send an advance instalment notice. This notice targets non-employment income and asks for periodic payments to spread your tax burden across the year.

Rental Income Earners
Owners of residential or commercial property who collect rent commonly receive the notice. Rental income is treated as non-employment income and is used to calculate expected tax for the year.
Keep clear accounting of rent received and expenses. Accurate reporting helps align instalments with your final income tax bill.
Freelancers and Business Owners
Freelancers, sole proprietors, and other small businesses that earn business income also get these notices. Royalties, commission, and side gigs count as non-employment income.
- Notices are based on prior-year records and reported earnings.
- Salaried workers only get a notice if they have secondary income streams.
- Use the correct form to update estimated amounts if your earnings change.
Tip: Maintain a tidy account and up-to-date accounting records. That reduces surprises when instalment payments are due.
Distinguishing Between PCB and CP500
If you earn salary and side income, two distinct collection systems may apply to you.
PCB (Potongan Cukai Bulanan) is an automatic monthly tax deduction your employer handles. It applies to regular employment income and deducts tax from each paycheck.
CP500 notice covers non-employment income. This system asks individuals to estimate tax and make six bimonthly instalments to the tax authority.
Key Operational Differences
Who pays and how often differ sharply. PCB is monthly and employer-driven. The advance instalment system is self-managed and bimonthly.
Mixed-income taxpayers must track both the monthly payroll deduction and the instalment amount for other income like rental income, commission, or royalties.
“Know which ledger covers your salary and which covers side earnings to avoid underpayment and penalties.”
| Feature | PCB (Payroll) | Advance Instalment Notice |
|---|---|---|
| Payer | Employer | Individual taxpayer |
| Frequency | Monthly | Six bimonthly payments |
| Applies to | Employment income / salary | Non-employment income (rental income, royalties, commission) |
| Calculation basis | Monthly tax tables | Prior year’s assessment and estimated amount |
- Check the form and payment schedule if you receive cp500 malaysia or similar notices.
- Track both systems to ensure your total income tax liability is met by year-end.
Navigating the Penalty Waiver for Year of Assessment
LHDN announced a temporary relief measure in January 2026 that affects advance instalment penalties for individuals who received the notice.
The waiver removes late penalty charges for all six bimonthly instalments in the Year of Assessment 2026. That gives new recipients extra breathing room while they learn the system.

Remember: the waiver covers only late penalties, not the original tax on your income. Your total tax liability for the year still builds up and will be reflected on your final return.
“The waiver eases short-term cash flow but does not cancel the underlying tax due.”
- Good for individuals receiving their first notice in 2026 who need more time to plan.
- Consider voluntary payments to reduce the chance of a large balance when you file your tax return.
- Maintain records and aim for ongoing compliance despite the temporary relief.
| Feature | What the Waiver Does | What Still Applies |
|---|---|---|
| Scope | All six bimonthly instalments for YA2026 | Underlying income tax amount remains payable |
| Penalty | Late penalties waived for 2026 | Penalties for other years or breaches still enforceable |
| Practical advice | Make voluntary payments if possible | File accurate return and pay outstanding tax by due date |
| Beneficiaries | Individuals newly included in the instalment system | All taxpayers remain responsible for the final tax assessment |
Managing Your Instalment Schedule
Plan your instalments early to avoid a last-minute scramble when your final tax return is due. A simple calendar and clear records make it easier to meet each due date and keep cash flow steady.
Payment Methods
You can settle your cp500 payment through the MyTax portal, online banking, or Interbank GIRO (IBG). Each channel posts a record to your account, so keep the receipts for accounting and future filing.
Due Dates and Deadlines
Instalments fall in March, May, July, September, November, and January. Each instalment must be paid within 30 days of the due date shown on the notice.
- The LHDN requires six bimonthly payments per year to spread your tax burden.
- Missing a due date normally triggers a 10% penalty on the outstanding amount; you must self-assess and pay it.
- Keep a tidy record of each payment receipt to support your annual return and compliance.
“Staying organized lets the system work as intended and prevents small lapses from growing into costly penalties.”

Revising Your Estimated Tax Liability
Significant changes in income let you correct advance tax instalments using an official revision form. If your business income or rental receipts differ sharply from last year, a timely update keeps payments aligned with reality.
Using Form CP502
Use Form CP502 to request a revision of your instalment amount. Submit the form when your forecasted tax deviates from prior assessments.
Deadlines for YA2026 are 30 June 2026 and 31 October 2026. File through the MyTax portal to ensure prompt processing.
- If actual income is much lower or higher, revise cp500 to avoid overpayment or a large balance at year-end.
- Note: if your revised estimate is 30% lower than the final tax payable, a 10% penalty may apply to the shortfall.
- Keep clear records of business and rental receipts when you submit form cp502.
“Proactive revision reduces surprises and keeps your tax position manageable.”
Integrating Tax Compliance with E-Invoicing
Automated e-invoicing helps businesses keep tight, auditable records for both reporting and tax planning. Digital records make it easier to prove revenue, reconcile receipts, and prepare instalment forecasts tied to your tax obligations.
The Role of Digital Records
Accurate digital records reduce disputes and speed reviews. When your sales, rental, commission, or royalties are recorded as e-invoices, your accounting ledger matches tax declarations more closely.
Phase 4 requires firms with annual revenue between RM1 million and RM5 million to issue LHDN-compliant e-invoice documents. That rule raises the bar for recordkeeping and audit trails.
Benefits of Automated Systems
Using middleware like JomeInvoice lets your existing accounting software send compliant e-invoices automatically. Integration with platforms such as AutoCount or Xero keeps bookkeeping current.
- Faster reconciliation: electronic records align income reporting with tax instalments.
- Less manual error: automation reduces missed entries for sales, rental, or commission.
- Security & trust: ISO 27001-certified middleware protects financial data during transmission.
- Self-billed support: useful for freelancers and businesses issuing invoices on behalf of partners.
“Integrate e-invoice flows with your accounting system to simplify compliance and improve forecasting.”
Tip: Link e-invoice reporting to your tax calendar so PCB, advance instalments like cp500, and final returns reflect the same income figures.
Conclusion
Stay proactive, and treat the advance instalment notice as part of routine tax planning. If you receive cp500, check due dates and track each cp500 payment to avoid surprises when you file your annual return.
Remember the 2026 penalty waiver is temporary. The underlying income tax amount still applies, so make voluntary payments if you can. Use the MyTax portal and Form CP502 to revise any incorrect amount.
For peace of mind, integrate e-invoice records with your bookkeeping and consult a qualified advisor if your salary, commission, or business receipts are complex. Good habits now save trouble later for individuals, salaried employees, and business owners.
