CP204 Tax Estimate Malaysia — How to Calculate

Updated April 2026 · Malaysian Tax Guide

CP204 is the estimated tax payable form that every Malaysian company must submit to LHDN (Inland Revenue Board). It determines your monthly tax instalment payments for the year. Getting it right avoids penalties.

What is CP204?

Form CP204 is a declaration of estimated tax payable for a year of assessment. Companies must submit it before the start of their basis period. The estimated tax is then paid in 12 equal monthly instalments.

How to Calculate Monthly Instalment

StepDescriptionExample
1Estimate chargeable income for the yearRM800,000
2Compute tax using applicable ratesRM147,000 (SME rates)
3Divide by 12RM12,250/month

Monthly instalment = Estimated annual tax ÷ 12. Due on the 15th of each month, starting from the 2nd month of the basis period.

CP204 Revision Rules

You can revise your CP204 estimate twice during the year:

Penalty for Underestimate

Under s.107C(9) ITA 1967, if your actual tax payable exceeds the CP204 estimate by more than 30%, a penalty of 10% is imposed on the difference.

Example: CP204 estimate = RM100,000. Actual tax = RM150,000. Difference = RM50,000 (50% over estimate). Since 50% > 30%, penalty = 10% × RM50,000 = RM5,000.
