Independent Software Vendors (ISV)

What is it?

The ISV’s software interfaces with SARS for the submission of various returns required by SARS.
The ISV service was initiated as an extension of the eFiling service. The software vendors approached SARS to integrate with the eFiling service that would reduce user effort and manage the process of completing tax returns.
The tax types serviced through the ISV service include:
  • Annual Returns :
    • ITR12
    • ITR14
    • IRP6
    • ITR12T
  • PAYE returns
  • Transfer Duty
  • Tax Directives (Tax Directive submissions have been allowed for a number of years via an interface that allows for the bulk request of directives)

See the letter on the ISV Tax Directives file submission migration to the new SFTP solution.

How does it work?

Secure access is enabled by a unique access key for the specific product and application. After user authentication is done, the interface interaction is allowed. The user is required to be an active user on eFiling with the appropriate rights.
Currently we have three categories of ISV’s:
  • Tax Returns Submissions
  • Transfer Duty
  • Directive Requests

Need Help?

You may forward the signed Terms and Conditions on email to It applies only to ISV’s requested authorisation for their systems to interface with SARS Systems.

For Tax Directives applications the existing process will continue whereby the interface specification and External Application for Access to SARS – Electronic Interface under “Form INF001” to register for access to SARS Interface are available in the Interface Specification IBIR-006 Tax Directives. Please note that the Terms and Conditions are also applicable to Tax Directive applications.
