CP500: Apply to amend instalment amount by 31 Oct 2025
Taxpayers who have received CP500 notices for YA 2025 are reminded to review instalment amounts and, if needed, submit an amendment (Form CP502) by Oct 31.
The CP502 form can be obtained from its official portal and submitted by hand, email, post, or online.
The amendment allows taxpayers to adjust instalments based on their estimated income and tax payable, either to increase or reduce the amount. Payments under the new approved schedule should be made using the designated bill number.
