How to qualify as an AIS Payroll Software Vendor

AIS payroll software vendors’ software must be able to support AIS submissions via API with effect from YA 2023 submissions.

Interested payroll vendors must complete the annual validation test conducted during Oct to Nov each year.

First time applicants email [email protected] by 31 Oct.

Do note that IRAS does not endorse your payroll software. Qualifying as an AIS payroll software vendor just means that the AIS submissions made through your software can be accepted by IRAS’ system.

We publish the list of AIS payroll software vendors and recommended controls for payroll software in the submit employment income records webpage.

Annual Validation Test

The validation test ensures that AIS submissions made through your software meets IRAS’ technical file format/ specifications requirements.

IRAS will notify you of the details for the validation test in Sep each year. You must perform a self-verification exercise to ensure that your payroll software can generate and output values according to the sample scenarios provided.

The following items must be submitted to IRAS by 30 Nov:

  1. A completed self-verification checklist

  2. Test files or Submission Reference No. submitted to API Sandbox

IRAS may conduct random checks on the submitted test file(s) to verify your validation test results. If the submitted test file(s) fail the validation test, you will not qualify as an AIS payroll software vendor.

Year of Assessment (YA) 2022 Validation Test

You only need to complete the validation test for the scenario that corresponds with the forms supported by your payroll software.
