Avoid common SMSF annual return errors before you submit

Learn how to avoid common issues when lodging your self-managed super fund annual return that can lead to delays.

Published 15 July 2026

Each year, a number of common issues arise in Self-Managed Super Fund (SMSF) annual returns (SARs) that can delay processing and create unnecessary rework. The good news is most of these errors are avoidable with a little extra care before lodgment.

When preparing the SAR, small oversights can quickly lead to delays. One of the most common issues is missing information.

Ensure all mandatory fields are completed, even if nothing has changed from last year. Pay particular attention to auditor details. Incomplete auditor details are another common issue.

Invalid or missing information

Returns are sometimes submitted without a valid auditor registration number (SAN) or before the audit has been fully finalised. To prevent this, make sure the audit process is complete and the trustees have received a copy of the signed and dated audit report prior to lodgment. Also make sure the correct SAN, auditor’s name and date the audit was completed is entered on the return.

Member information is another frequent area where errors are made. Missing or invalid TFNs can lead to processing delays. Always verify TFNs directly against your client records rather than relying on pre-filled or previously lodged data.

Errors in dates is another recurring issue. Dates may be entered incorrectly or in the wrong format. Reviewing key dates, such as the financial year end and audit completion date, can help catch these errors early.

We also see instances where values entered don't align with approved options. Where dropdown menus are available, use them instead of manually entering values to avoid mismatches with approved lists.

In addition, yes or no boxes are sometimes missing or invalid. A quick scan of all such questions before submission can confirm each one has been answered appropriately, streamline the lodgment process, and reduce the likelihood of delays or rejections.

Final checks make a difference

Make sure you use the relevant SAR and instructions for the lodgment year. For your 2026 return you can use the Self-managed superannuation fund annual return 2026 instructions to complete your 2026 SAR.

Spending a little extra time reviewing your SAR before you lodge can help reduce the likelihood of errors, ensure smoother processing and avoid unnecessary delays.
