If your SMSF doesn't use an SMSF intermediary such as an SMSF administrator, tax agent, accountant, or some banks, you'll need to register directly with an SMSF messaging provider.
Your SMSF messaging provider will give you the alias it uses as its active ESA.
To receive SuperStream data, your self-managed super fund (SMSF) needs an electronic service address (ESA).
An ESA is an alias that represents the uniform resource locator (URL) or internet protocol (IP) address of a messaging provider. It ensures you meet all technical requirements for interacting electronically across the super network. An email address is not an ESA.
You can get an ESA from an SMSF messaging provider or through your SMSF intermediary such as SMSF administrator, tax agent, accountant, or some banks. Many of these options are no cost or low cost.
Once you have obtained or updated your ESA, notify the ATO. See the Electronic service address on the ATO website.
