SMSF annual return due date: every lodgement date and deadline that matters

The SMSF annual return is one form that does four jobs: it's the fund's income tax return, its regulatory return to the ATO, the report of every member's contributions, and the way the fund pays the ATO's supervisory levy. It can only be lodged once the independent audit is finished, and its due date depends on whether you use a tax agent and on the fund's lodgement history.

This guide sets out the due dates for 2025–26 returns, how to work out your fund's date, the auditor appointment deadline that sits behind it, a month-by-month calendar of the other SMSF deadlines, and what happens if you're late. All dates here are from the ATO's lodgement program as at October 2026.

When is the SMSF annual return due?

If you lodge through a tax agent (2025–26 returns)

If prior-year returns that were outstanding are all lodged by 31 October 2026, the fund's 2025–26 return goes back to its normal due date.

If the trustees lodge the return themselves

If a due date falls on a weekend or public holiday, you can lodge and pay on the next business day.

Key point: A tax agent's later dates only help if the agent has the fund on their lodgement program before the self-lodger date passes. If your fund doesn't have an agent and you appoint one in March, ask straight away what your fund's date is.

When must the SMSF auditor be appointed?

The trustees must appoint an approved SMSF auditor at least 45 days before the return is due. Working back from each due date:

Appointing the auditor isn't the same as finishing the audit. The audit has to be completed, and the audit report received, before the return is lodged, because the return reports the auditor's details and the outcome. In practice, the accounts need to be ready well before the due date. Our SMSF audit guide explains what the auditor needs from you.

What's in the SMSF annual return?

The return covers the fund's whole year in one place:

• Fund details: the fund's name, ABN, auditor details and audit outcome, and whether the fund was wound up during the year.
• Income: interest, dividends and franking credits, rent, trust distributions, capital gains, assessable contributions, and any non-arm's length income.
• Deductions: expenses the fund can claim, reduced where part of the income is exempt.
• Tax calculation: tax on taxable income (generally 15% for a complying fund, with non-arm's length income at 45%), exempt current pension income, credits and offsets, PAYG instalments paid, and the supervisory levy.
• Losses carried forward.
• Member information: each member's opening and closing balance, contributions by type, rollovers, and benefit payments. This feeds the ATO's records of each member's total super balance and contribution caps.
• Assets and liabilities: what the fund holds, by type, including any limited recourse borrowings and related-party investments.

The supervisory levy has been $259 a year for an established fund since 2014–15 (paid in advance for the next year), and $518 on a newly registered fund's first return, covering two years. Check the ATO's current figure before you pay.

Because the member information drives each member's caps and total super balance, mistakes in the return show up later as wrong figures in members' own ATO records. That's another reason to get it right first time.

What is the full SMSF calendar for 2026–27?

The annual return is one deadline among many. Here's a typical year for a fund lodging through a tax agent with a 15 May due date and at least one member in pension phase.

Transfer balance account reports are needed only when a reportable event happens, such as a pension starting or a commutation. Regular pension payments aren't reported. Our SMSF pensions guide explains what counts.

The 30 June traps

Most SMSF breaches happen around 30 June, because two rules depend on money actually moving by then.

• Contributions count when the fund receives them, not when you send them. A transfer made on 30 June that lands on 1 July counts in the next year, which can push you over a cap. Employer contributions now arrive with each pay run under Payday Super, but still allow time at year end. See contributions and caps.
• Pension minimums must leave the fund by 30 June. If the minimum isn't paid, the pension may be treated as having stopped from the start of the year, and the fund can lose the tax exemption on that pension's income. Pay in early June, not on the last day.

What happens if you lodge the SMSF annual return late?

Late lodgement has three kinds of consequence.

Penalties. The ATO can apply a failure to lodge on time penalty of one penalty unit for every 28 days (or part) the return is overdue, up to five units for a small entity. With the penalty unit at $364 for returns due from 1 July 2026, that's up to $1,820 for most funds, and more for larger entities. The ATO can remit penalties, but don't count on it. Interest also runs on tax paid late.

Fund status. If a return is overdue, the ATO may change the fund's status on Super Fund Lookup to "regulation details removed". Employers and other funds check that status, so it can stop rollovers and employer contributions reaching your fund. Paper returns can take up to 50 days to process, so lodging on paper close to the date risks the same thing.

Compliance attention. Overdue funds move onto the earliest lodgement date the next year, can lose access to tax concessions, and attract ATO compliance action. A fund with several years outstanding needs each year's accounts and audit done in order, which takes time. If that's you, start now; our SMSF accountant service regularly rebuilds overdue funds.

Lodgement mistakes we see most

• Assuming every fund gets 15 May. A fund that was late last year, or is new, has an earlier date. Check each year.
• Appointing the auditor after the 45-day cut-off. The audit can still happen, but the trustees have missed a legal time limit, and the audit is squeezed into less time than it needs.
• Lodging without the audit report. The return asks for the auditor's details and the audit outcome. Lodging first and auditing later is a breach in itself.
• Wrong member contribution figures. These flow into members' caps and total super balance. An error can trigger an excess contributions determination for a member that wasn't actually over.
• Forgetting the levy on a first return. A new fund pays $518, not $259.
• Old contact details at the ATO. Lodgement reminders and penalty notices go to the address on file. Changes must be notified within 28 days.

When is a new SMSF's first annual return due?

A new fund's first return covers the period from establishment to the first 30 June. When lodged through a tax agent, it's due on 28 February after that 30 June, unless the ATO told you at the end of its registration review to lodge by 31 October. A new fund lodging its own return is due by 31 October.

The first return includes the supervisory levy for two years. If the fund didn't start operating until after 30 June, or never held assets, ask whether a return is actually needed for that period. Our guide on how to set up an SMSF covers the first year in more detail.

When is the final return due for a fund that's winding up?

A fund that winds up during the year still lodges a final annual return for that year, after a final audit. The return records that the fund was wound up, the wind-up date, and an adjustment to the levy. Lodging it is what tells the ATO to close the fund and cancel its ABN. Our winding up guide covers the order of steps.

How do we keep your SMSF ahead of the deadlines?

We confirm your fund's due date at the start of each year and work back from it. In practice:

1. In July and August, our year-end records request agent builds your document list from last year's figures and sends it by SMS or email. You upload statements from your phone.
2. We prepare the accounts, member statements and minutes, and check caps, pension minimums and related-party issues before the file goes to the auditor.
3. We appoint and brief the independent auditor well ahead of the 45-day deadline, and handle their queries.
4. We lodge the return as your tax agent once the audit is signed, and tell you the tax and levy to pay and the date.
5. During the year, we lodge transfer balance account reports as events happen and remind you before the 30 June cut-offs.

Our super and SMSF agent drafts the compliance calendar and the technical checks for your fund, and a qualified accountant reviews every figure and signs off before anything is lodged.

What should you send us, and when?

Getting records to us early gives the audit time to run without pressure. Leave it to April for a 15 May due date and something will be rushed.
