Keep your STP submissions running without interruption to the ATO by registering your SSID in the ATO Access Manager
If you haven't yet lodged your SSID with the ATO, your STP submissions are currently failing, and you'll need to complete this declaration to get them flowing again.
The SSID is a shared identifier between your ABN, foundU (as your payroll platform and STP gateway), and the ATO. It acts as a verified link, ensuring your payroll data is sent by an authorised party.
The good news? We’ve already done the heavy lifting for you. foundU has automatically generated an SSID for every ABN in your account, so that part is taken care of. All that’s left to do is lodge it through the ATO Access Manager portal; a quick and straightforward process!
In this article, we will cover:
- What an SSID is and how it works
- How to locate your SSID and lodge it with the ATO
- FAQs about SSID declarations
Please note: The 'Access Office codes' permission is required to view SSID numbers on the Office code page.
A Software Subscription ID (SSID) is a unique identifier linked to your ABN that authorises your payroll data to be sent to the ATO. It forms part of updated ATO requirements for Single Touch Payroll (STP), ensuring that all submissions come from a verified and authorised source. You can think of it like a secure 'address label' on your payroll data, confirming exactly who it’s coming from.
The SSID creates a trusted connection between your business, your payroll software (foundU), the sending service provider (SSP), and the ATO. This added layer of security helps protect your data and ensures compliance with the latest ATO standards.
Key facts to be aware of:
- foundU acts as both your payroll platform (DSP) and the STP gateway (SSP)
- If you manage multiple ABNs, each must be registered separately
- Registered agents have their own ABN and therefore their own SSID
- The person in your business with access to the ATO Access Manager will need to lodge the SSID in the declaration section
Once your SSID is registered with the ATO, you will not need to perform this process again unless you take on new businesses with new ABNs.
The process below takes place within foundU and the ATO's Access Manager portal. It's best to have a designated person in your business with access to both. If you haven't already registered your SSID, your STP submissions will continue to fail until this is completed, so you'll need to do this as soon as possible.
This process will involve 2 steps, which we will cover below:
- Locating your SSIDs in foundU
- Inputting those SSIDs for each ABN in foundU
Let's look at detailed instructions for both below.
Hot tip: You'll need to copy your SSID for each ABN that you pay through. If you have multiple ABNs, you'll want to have one screen open with foundU and one with the ATO Access Manager.
To locate your SSIDs in foundU:
-
Navigate to the main menu > Payroll Settings > Office Codes, then select the relevant office code (paying entity) for the ABN you want to register. In the Tax Declaration details, locate the SSID field. This lists the SSID generated for that ABN.
- Copy your SSID for the relevant ABN - Copy the SSID exactly; you'll need it for the next step in the ATO Access Manager.
Please note: Old ABNs linked to inactive Office codes don't need ATO registration or action.
Follow the steps below to lodge your SSID with the ATO through the Access Manager portal. You only need to do this once per ABN.
To authorise foundU within the ATO Access Manager:
-
Log in to Access Manager and locate your hosted software services - Log in to Access Manager at ato.gov.au, then select My hosted software services > Notify the ATO of your hosted service.
-
Search for foundU - Search for the software provider's ABN or name. Type foundU (this is case-sensitive; use a lowercase 'f'). Next, select the ABN link that appears.
-
Enter your SSID - Paste the software ID (SSID) you copied from your foundU Office Codes page into the software ID field, then select Next.
-
Review and save - Review the details shown, then select Save. A success message will appear confirming the hosted software service provider has been saved successfully.
Once your SSID has been successfully lodged and saved in the ATO Access Manager portal, your STP submissions for that ABN will begin processing again. There's no further action needed in foundU.

I have just moved to foundU. Can I use the SSID from my previous platform?
No. SSIDs are unique to each payroll platform. foundU has generated a new SSID for your ABN automatically, and you will need to register this SSID to the ATO.
What if we use a registered agent to perform STP-related tasks?
A registered agent will have their own ABN and, therefore, their own SSID to lodge within the ATO Access Manager portal. They can find their SSID by logging in to their admin account and navigating to the person icon in the top-right corner of the platform. From there, they will need to select Admin Profile and find their SSID.
After lodging this in the Access Manager portal, any STP-related tasks they perform in your platform will be sent to the ATO with their registered agent SSID.
What happens if I haven't registered my SSID yet?
STP submissions for that ABN will continue to fail until the SSID is registered. Complete the declaration as soon as possible to restore your submissions.
Where can I find my SSID after setup?
Your SSID is always accessible on the Office Codes page in foundU (Payroll Settings > Office Codes), listed under the relevant office code/ABN.
What will happen if we process STP before we have lodged our SSID?
The STP submission will fail, and an error will be returned until the SSID has been registered with the ATO.
Will I need to complete this process again after declaring my SSIDs prior to 30 June 2026, or is this the only time I will need to do this?
Yes and no.
Once you've registered your existing SSIDs, you won't need to repeat the process for those ABNs. However, if you create any new paying entities in the future, a new SSID will be generated for that ABN. When that happens, you'll simply need to lodge the new SSID with the ATO.
When that happens, you’ll simply need to lodge the new SSID with the ATO at that time. You can find the SSID for you new pay entity on the Office codes page.
