[YA 2026] Making Changes Post Submission

Overview:

Under S68(2) of the Singapore Income Tax Act of 1947, Employers in Singapore are required to prepare and submit employment income details. Each March 1st the Inland Revenue Authority of Singapore (IRAS) receives IR8A reports that include complete income details for the prior year of every employee. The guide delivers a detailed explanation which shows employers step-by-step procedures for IR8A filing through payroll software to meet all IRAS regulations.

Is it possible to make changes after submission?

While it’s best practice to thoroughly review all details before submitting the Singapore IR8A form and its supporting documents, errors can still occur. If you identify mistakes in employee details, income amounts, or deductions, promptly submit an amendment file.

You can easily update the amount in the MyTax portal by revising the difference and entering the correct figures if you need to adjust your employee’s income information after submitting the forms electronically.

You can amend the submission depending on whether IRAS has processed it:

• Before Processing:
  Simply re-submit the corrected IR8A form via myTax Portal.
  
  
• After Processing:
  1. Submit an amendment file via myTax Portal
  2. Update only the affected employee records
  3. Specify any changes in amounts
  4. If the amendment affects IR8A figures, also amend IR8S, Appendix 8A, or Appendix 8B, if applicable
  
  
• For Major Errors:
  Employers must email IRAS (iras@iras.gov.sg) and request withdrawal of the incorrect submission.
  
  

Be sure to complete any amendments before the deadline of March 31st to avoid penalties.
