One-Stop Payroll
The One-Stop Payroll initiative is a joint effort by IRAS, CPFB, MOM, and GovTech to simplify payroll and employment-related regulatory requirements. It allows businesses and employers to submit payroll and employment-related information to multiple Government agencies directly from their payroll software. In addition to annual salary data submission under AIS to IRAS, One-Stop Payroll vendors can also support the seamless submission of monthly CPF contributions and other data to CPFB, and responses to MOM surveys. Find out how you can stand out as a payroll solution by integrating One-Stop Payroll.

Payroll software for AIS submissions
Payroll software that supports AIS submissions must be able to integrate directly with IRAS' server to submit employment income information through Application Programming Interface (API).
How to qualify as an AIS payroll software vendor
To qualify and be listed as an AIS payroll software vendor at the #SFFS Solution Partners listing for a particular Year of Assessment (YA), you must fulfil all of the following criteria:
- The payroll software vendor should be the developer of the software. Software distributors, resellers or payroll service providers will not be listed.
- The payroll software vendor must complete an annual validation test conducted by IRAS, typically between Sep-Nov of the preceding YA.
- The payroll software must be able to support AIS submissions via API, in accordance with the technical format/ specifications requirements. Refer to the technical format/specifications to confirm whether your payroll software meets the API integration requirements. If it does, proceed to register your interest with IRAS via the form by 30 Sep each year.
Do note that IRAS does not endorse your payroll software. Qualifying as an AIS payroll software vendor means that the AIS submissions made through your software can be accepted by IRAS’ system.
