From 1 July 2026, when Payday Super commences, there will be less time to fix errors, so data accuracy matters more than ever. The good news? The introduction of new SuperStream standards aims to improve superannuation contribution efficiency, accuracy and timeliness. Plus, understanding new error messages, what causes them, and how to fix them now will help save you time, reduce refunds, and keep contributions flowing smoothly on payday.
Common super error messages and how to fix them
Here are four super error messages employers see most often and how to avoid them or fix them.
-
Member not found / No account exists
This is the most common error message and usually the simplest to fix. It generally means the employee details you’ve sent don’t exactly match what the fund has on file, or the employee doesn’t have an active account with that fund. Even small differences, like a different surname or incorrect date of birth can cause a mismatch.
How to avoid it
- Double check the basics before you submit: USI, account number, TFN, date of birth, and the employee’s first and last name.
- Check details required format (e.g. date of birth).
How to fix it
- Ask the employee to confirm their super fund details.
- Ensure updates are made in your payroll system, not just in the contribution file.
- Resubmit the contribution once the details are correct.
-
No longer a member of the nominated fund
This usually happens when an employee has changed super funds, but payroll records haven’t been updated yet.
How to avoid it
- For new starters, confirm they have an open account with the fund they’ve nominated.
- For existing employees, make sure any fund change requests are updated in payroll before the next pay run.
How to fix it
- Check whether the employee has changed funds, and if not, ask them to confirm their details directly with the super fund.
- Review their member details, update anything that’s incorrect, resubmit the contribution and update your payroll system.
-
Contribution can’t be accepted (age or eligibility)
This message usually relates to voluntary contributions, such as salary sacrifice, where additional eligibility or identity requirements apply.
How to avoid it
- Before processing voluntary contributions, confirm the employee meets the ATO’s eligibility rules.
- Make sure the employee’s TFN is recorded correctly.
What happens next
- If a contribution can’t be accepted, it will be returned to you.
- As it’s not a mandatory SG payment, you should pass the amount back to the employee.
If the employee believes they should be eligible, they can review the rules on the ATO website and contact their fund to check whether their account details need updating.
-
Payment doesn’t match the contribution file
With Payday Super, this one becomes critical. The payment amount must exactly match the contribution file. Even a one cent difference can result in the contribution being refunded.
How to avoid it
- Always check that the payment amount and contribution file align perfectly before submitting.
If there’s a mismatch
- If you've overpaid, generally the clearing house or super fund will allocate what's in the file and refund the difference.
Clearer super error messages, faster fixes
To make errors easier to fix, the ATO is improving SuperStream error messaging under Payday Super. Instead of generic messages, employers will see clearer, standardised responses that explain exactly what’s wrong and what needs correcting. This makes it quicker to resolve issues and resubmit contributions when super is paid alongside salaries and wages under Payday Super.
| ERROR SCENARIO | MESSAGE BEFORE PAYDAY SUPER | MESSAGE AFTER PAYDAY SUPER |
|---|---|---|
| Missing surname | Mandatory data element not supplied. | Mandatory data element not supplied – SURNAME is mandatory and MUST be provided. |
| Incorrect date format | Data element contained an unexpected value. | Data element contained an invalid value – Member DOB MUST be set to DD/MM/YYYY. |
Preventing super errors before they happen
Another improvement introduced as part of Payday Super is the new Member Verification Request (MVR). They’re typically used when paying a fund for the first time, after a rejected contribution, or when employee details change. This means MVRs should form part of your employee onboarding process when a new starter chooses a fund, or when an existing employee changes funds. MVRs ensure contributions are accepted by the fund and applied correctly to a member account, reducing errors, rejected payments and refunds. In certain situations, MVRs allow you to check whether an employee’s details match an active super account before you make a contribution through your clearing house or payroll provider. Super Funds have until March 2027 to fully implement MVRs.
