Highlights

  • The ATO is urging SMSF trustees to carefully reconcile figures before lodging their annual return.
  • Limited recourse borrowing arrangement figures should be consistent across all relevant sections of the SAR.
  • Duplicate or premature amendments can complicate processing and should be avoided.
  • A final pre-lodgment review can reduce delays caused by mismatched or inconsistent information.

The Australian Taxation Office is encouraging self-managed super fund (SMSF) trustees to slow down and check their numbers before lodging the SMSF annual return (SAR).

In guidance published in August 2026, the ATO highlighted common reporting issues that can delay processing and may be avoided through a careful pre-lodgment review. Getting the details right the first time can help the return move through processing more smoothly and reduce the need for follow-up corrections.

Check calculations and reconcile totals

The ATO's first message is to check calculations and reconcile totals across the different sections of the return.

Figures should be internally consistent, meaning an amount reported in one part of the SAR should align with related information elsewhere.

Simple arithmetic, transposition and reconciliation errors can lead to inconsistencies that require further checking.

Trustees and their advisers should therefore review totals against the fund's financial statements and supporting records before lodging.

Align your LRBA figures

Limited recourse borrowing arrangement figures deserve particular attention.

The ATO notes that LRBA amounts should align across all relevant sections of the return and that inconsistencies can contribute to processing problems.

Trustees with an LRBA should reconcile the borrowing, associated asset and related reporting before lodging.

Where property has been acquired, refinanced or revalued during the year, extra care may be needed to ensure the figures reported in the SAR remain consistent with the fund's accounts and supporting documentation.

Do not lodge premature amendments

The ATO also cautions against lodging duplicate or premature amendments.

If a return is still being processed or has been suspended, submitting amendments before the original lodgment has been finalised can complicate processing.

Where an error is identified after lodgment, trustees should generally avoid creating overlapping submissions and follow the appropriate amendment process once the original return has progressed, unless the ATO provides different instructions.

The aim is to maintain a clear processing trail rather than adding unnecessary duplication.

Who may be affected

Every SMSF Trustee required to lodge a SAR may be affected, along with tax agents and administrators preparing returns on behalf of funds.

More complex SMSFs may face a higher risk of inconsistencies simply because there are more figures to reconcile.

Funds with limited recourse borrowing arrangements, multiple asset classes or more complicated member transactions may therefore benefit from an additional review before submission.

What to consider next

Before lodging, trustees should reconcile totals across sections, confirm that LRBA figures are consistent and review member information and allocations for accuracy.

The final return should also be checked against the SMSF's financial statements and relevant records.

If a return is already being processed by the ATO, trustees should avoid rushing to lodge another version without first considering the correct amendment process.

A short review at the end of preparation can be considerably easier than resolving inconsistencies after lodgment.

Why small errors cause big delays

The ATO processes a large Volume of SMSF annual returns, and inconsistent information can require further review before processing is completed.

Where related figures do not reconcile, the ATO may need to clarify or review the information before the return can progress.

LRBA reporting is a particular area where consistency matters because the borrowing and associated asset information can appear across different parts of the return.

Trustees should therefore make sure that the figures tell a consistent story and align with the fund's underlying records.

This is particularly relevant where an LRBA has changed materially during the financial year.

Lodge once, lodge right

The ATO's caution against premature amendments reinforces the broader message: it is better to spend additional time checking the first lodgment than to create unnecessary corrections afterwards.

A careful pre-lodgment review should cover calculations, related balances, LRBA information and member details.

Where an error is identified after the SAR has already been submitted, trustees should follow the appropriate ATO amendment process rather than automatically lodging another return while the first remains unresolved.

The overall message is simple: accurate, internally consistent reporting at the outset can make the SMSF annual return process more efficient for both trustees and the ATO.
