If you have made an error in your submission regarding your employees' ID, income and deduction amounts or fields that affect the amounts that were submitted, you must submit the amendment file immediately. You may also use the Amendment Checker (XLSM, 85KB) to find out if an amendment submission is required.

If amendment is required to correct the error, there are 2 ways to prepare your amendment file:

1. Revision submission (Recommended) – Overwrites your previous submission(s) with the latest values.
2. Amendment submission – Updates only certain fields by adding or subtracting values.

You must choose your submission method before creating the amendment file, as it affects how your records will be processed and the amounts that you need to submit. 

Refer to Amend Submitted Records for the detailed amendment submission steps.
