API Roadmap 2.0



Introducing IRAS API Roadmap 2.0



In line with the Smart Nation initiative to help SMEs stay relevant and competitive, the API Roadmap offers solution providers the opportunity to create new innovative products that digitalise operations and improve productivity. IRAS APIs can help build a rich eco-system of possibilities that can deliver a Seamless Tax Experience for taxpayers and tax agents. Building on the previous roadmap, new capabilities, enhancements and offerings are now available for software developers to build on and integrate with IRAS seamlessly through the use of APIs.






A refreshed API Roadmap that outlines what's new1 and upcoming, and key initiatives for Accounting & Taxation, Payroll & Income, Property and Service Enablers. More details on each API can be found on the API Products page




A new space for possibilities and collaboration of APIs that would significantly enhance the future state of integrated software.




To truly make accounting, tax and payroll software more competitive and relevant to meet expectations of taxpayers of tomorrow.




Put together the APIs that you need to help shape the desired solution fit for your business.
