AIS Quick Guide: Choosing Revision or Difference-Only Amendment

AIS revision replaces the prior record with full correct amounts; amendment adds only differences and leaves unaffected fields blank.

Source checked · 11 October 2026 · Document date: 15 Sep 2025

Choose the method before entering amounts

In myTax Portal open Employers > Submit Employment Income Records, select Create, choose the correct year and Modify previously submitted data, then select the method and Proceed. The 15 September 2025 guide warns that the choice changes processing and the amounts required. Do not enter the same values under both methods.

Revision versus amendment

Revision requires full correct values for every relevant field and overwrites the previous records. Amendment reports only the change: positive additional amounts or negative amounts for over-reporting, with unaffected fields blank. Prepare Appendix 8A/8B when necessary and select Update to save. Saving does not itself submit the change.

Records, contact and final submission

Use New Record, Retrieve from Past Submission for personal particulars or the prescribed Excel template. The source schedules retrieval/Excel import for mid-October 2025, a historical rollout note. Fill submission contact details, tick the declaration and Submit. A successful submission gives an acknowledgement page and number.
