SMSF contribution reserving explained

SMSF contribution reserving Explained Contribution reserving is also known as deferred allocation of contributions. SMSFs are in a unique position. The trustee can allocate contributions to a member account within 28 days after the end of the month in which the contribution is received, rather than within 3 days, as is the rule for other types of super funds. The trustee can hold a contribution received in June in Year 1 and allocate it to a member by 28 July in the next year, Year 2. The tax deduction can be claimed in Year 1, while the contribution isn’t counted towards the member’s contribution cap until Year 2.

Why undertake contribution reserving?

A contribution-reserving strategy is highly effective for individuals expecting a high tax bill, such as from bonus income or a capital gains windfall, who can maximise their personal super deduction by obtaining a ‘double tax deduction’ (twice the contribution cap) but don’t need a tax deduction in the next year.

Example – Betty is 69, and her employer pays the maximum SG without exceeding her contribution cap. She retires at the end of Year 1 and doesn’t have sufficient income to claim a personal tax deduction in Year 2, so she can make an additional personal contribution and claim it in Year 1 by using the contribution reserving strategy via her SMSF, as she is eligible to claim a tax deduction without exceeding her contribution cap in Year 1.

How does the strategy work?

Example – Fred’s family company contributed $65,000 to his SMSF in 2026/27 (Year 1), with $32,500 on 5 May 2027 and $32,500 on 20 June 2027. The SMSF trustee defers allocation of the June contribution to Fred’s member account until 1 July 2027. The fund holds the deferred contribution as an unallocated contribution in Year 1, and allocates it to Fred’s member account in 2027/28, Year 2.

The maximum concessional contribution in Year 1 is capped at $32,500.
The deferred contribution of $32,500 is not counted towards the member’s contribution cap in Year 1.
It does count towards the member’s contribution cap in Year 2.
The fund is taxed on the deferred contribution in the year it is received, Year 1. Based on the above example, the fund would be taxed $9,750 ($65,000 x 15%) on taxable contributions received in Year 1.
Fred’s family company would receive a tax deduction of $65,000 in Year 1, which would effectively be a tax saving of $19,500 or $16,250 depending on whether the company was taxed at 30% or 25%, respectively. Alternatively, if Fred made the contribution personally and was eligible to claim a tax deduction at his top marginal tax rate of 45% (excluding Medicare), the tax savings would be $29,250.
Ensure concessional contributions are counted from all sources, not just from your SMSF.
Ensure there is no existing contribution reserving strategy in place from the prior year.

Application of the contribution-reserving strategy

Consider a couple of scenarios when applying the contribution-reserving strategy.

Scenario 1 – Paul expects a large tax bill in 2026/27 because he received extra bonuses at work. His employer regularly pays super to his SMSF and makes the maximum super guarantee contributions (SG contributions) allowed. Paul wants to bring forward a tax deduction to reduce his 2026/27 tax. He plans to contribute $32,500 on 25 June 2027 and claim a personal tax deduction, bringing his total concessional contributions to $65,000. However, Paul’s financial advisor tells him he will exceed his concessional contribution cap in 2027/28 because his employer must make SG contributions during the year. The $32,500 he plans to contribute on 25 June 2027 will max out his 2027/28 contribution cap, so his employer’s monthly SG payments in 2027/28 will automatically exceed the cap.

Scenario 2 – James is self-employed and, due to a very profitable year, expects a large tax bill in 2026/27. Therefore, he wants to bring forward a large tax deduction. He made super contributions of $32,500 on 30 May 2027 and another $32,500 on 28 June 2027 to his SMSF, for a total of $65,000. He is eligible to claim $65,000 as a personal tax deduction in 2026/27. His SMSF has allocated the $32,500 contribution made in June to an unallocated contribution account in 2026/27 and will allocate it to James’s super account on 1 July 2027 (2027/28). He has now maxed out his contribution cap for 2027/28. He can make another eligible personal contribution of $32,500 in June 2028 and claim it as a tax deduction in 2027/28, because his SMSF will use the same strategy to allocate the June 2028 contribution to an unallocated contribution account and allocating it to his super account on 1 July 2028 (2028/29).

However, no double taxation deduction is available, as it applies only in the first year of the strategy’s initial use.

Assumption – the concessional contribution caps do not change in 2027/28 or 2028/29.

Warning – Applying the reserving strategy may set up an ongoing rolling strategy which must continue to ensure the concessional contribution cap is not exceeded in future years.

What is the process to get an SMSF contribution reserving strategy right?

First, check the fund’s trust deed to ensure there is no limit on allocating contributions beyond the legal requirement to allocate them within 28 after the end of the month; i.e., ensure the deed does not require the contributions to be allocated as soon as they are received by the trustee.

The following documentation should be obtained to make the process transparent:

Evidence of the type, amount, and date the contribution was made.
The trustee should prepare a resolution in Year 1 to evidence the decision to use the contribution reserving strategy; it should include the amount of contribution received, the date, the type of contribution and that it is being allocated to an unallocated contribution account, as it is technically not a reserve.
The trustee should prepare a resolution in Year 2 showing the amount and type of contribution to be allocated to a specific member and the date of the allocation, which should be no later than 28 July of Year 2.
The ATO has made it clear that a deferred contribution should be made as a separate transaction and cannot be part of a larger cash or in-specie contribution; i.e., a $45,000 contribution made on 10 June cannot be split, such as allocating $32,500 as a Year 1 concessional contribution and $12,500 deferred to Year 2 and allocated as an ‘unallocated contribution’ in Year 1.
Notify the ATO that the SMSF is using the strategy via a “Request to Adjust Concessional Contributions”. The member, not the SMSF, must lodge the form. The member’s tax agent can lodge this via the portal, which makes the process much more efficient.

We can assist our SMSF clients with this process, but as we are not the member’s personal tax agent, we cannot lodge it via the tax portal. We are happy to liaise with your personal tax agent.

This form cannot be used to advise the ATO for deferral of non-concessional contributions.

Get your timing right

Timing is absolutely crucial to getting this strategy right.

Trustee Resolutions

The initial resolution acknowledging the receipt of the contribution and allocation to an “unallocated contribution account” must be made before the deferred contribution is received.

The second resolution allocating the contributions to a specific member must be made by 28 July in Year 2.

ATO “Request to Adjust Concessional Contributions”

All concessional contributions, including deferred contributions, made in Year 1 are included in the tax return section of the fund’s annual return and taxed in the same year. In the member section of the annual return, the contributions are also reported as if allocated to the member. The member must complete and lodge the “Request to Adjust Concessional Contributions” to have the ATO adjust them to Year 2 for the purposes of correctly tracking the member’s concessional cap for the relevant year.

Because of the ATO’s administrative processing, it often issues incorrect excess concessional contribution notices, causing unnecessary follow-up. To avoid this pitfall, it is best to lodge the request, via paper or have the member’s personal tax agent do this via their tax agent portal, at least 6 weeks prior to the lodgement of the fund’s SMSF Annual Return and the member’s personal tax return.

Claiming a member concessional contribution

The critical paperwork in claiming a personal tax deduction for superannuation contributions includes:

a written notice of intent to claim a tax deduction, setting out the amount the member is claiming in their tax return, must be given to the SMSF trustee, and
the trustee acknowledges and accepts the member’s intent

The intent to claim a tax deduction can be provided to the SMSF trustee in Year 1, when the contribution is received. The trustee acknowledges this intent when the contribution is allocated in Year 2. Typically, the trustee acknowledges this on 1 July in Year 2 to ensure the contribution is eligible to be included in a new pension being started or when a spouse is splitting their contribution. A late trustee acknowledgement could put the tax deduction at risk.

What happens if the strategy fails?

If the strategy fails, the ATO will most likely allocate the contributions to a member in the year they were received. The effect of the failed deferred contribution will depend on whether it is a concessional or non-concessional contribution.

Example – Failed deferred contribution of $32,500 received on 10 June 2027

Pauline is 42 and self-employed. She did not provide her SMSF trustee with a valid ‘Notice of intent to claim a deduction for personal super contributions’ made on10 June 2027. Pauline’s TSB at 30 June 2026 was $1,100,000. She had not previously triggered the bring-forward rule. Pauline made an eligible personal member contribution of $32,500 on 1 May 2027, and non-concessional contributions of $390,000 on 10 January 2027 after receiving a payment from her mother’s estate.

The contribution reserving strategy failed. She was eligible to make a member contribution on 1 May because she provided the trustee with the correct paperwork, and the trustee acknowledged it the next day. She was also eligible to use the bring-forward rule and contribute a $390,000 non-concessional contribution. However, the contribution made on 10 June 2026 is invalid and is now allocated as a non-concessional contribution, exceeding her non-concessional contribution cap.

The ATO will send her an excess non-concessional contribution determination, and she can elect to:

release the excess non-concessional contributions (ENCC) plus 85% of the associated earnings (calculated by the ATO), or
don’t release the ENCC and pay excess non-concessional contributions tax
Pauline can ignore the determination and the ATO automatically sends her SMSF a ‘Release Authority’

Under options 1 & 3, Pauline’s SMSF, on receipt of a ‘release authority’, must release the ENCC of $32,500 plus 85% of the associated earnings to the ATO. The ATO will refund this to Pauline after any outstanding tax or Australian Government debt is paid. The ATO will send Pauline an amended tax return to include the associated earnings. She will also receive a 15% tax offset of the associated earnings.

Under option 2, the ATO will send the fund an ENCC tax assessment, and the fund must pay 47% of $32,500 ($15,275) in tax, but Pauline can elect to have the tax released from her SMSF. This option is draconian and rarely applied.

Example – Failing to send the ATO “Request to Adjust Concessional Contributions”

Similar facts to the example above, except the notice of intent and the trustee acknowledgement are valid for the 10 June contribution. The contribution reserving strategy fails, and the $32,500 is now classified as excess concessional contributions (ECC).

The ATO will include ECCs in Pauline’s assessable income and tax them at her marginal tax rate (MTR), less a 15% tax offset, and will send her an amended tax assessment. If her MTR is 47% (incl. Medicare), tax of $10,400 would apply after allowing for the offset.

Pauline can elect to withdraw $27,625 from her SMSF, being 85% of $32,500. The fund must release it to the ATO, then the ATO will refund it to her after paying any outstanding tax or other Australian Government debt.

If Pauline does nothing and the ECCs are not released from the fund, the ATO will still include the ECCs in her tax return; she will pay $10,400 in tax, and the ECCs will also count towards her ENCC, as she has already maxed out her non-concessional contribution cap. As in the first example, she can then elect to withdraw the ENCC plus 85% of the associated earnings, with the associated earnings added to her assessable income.

Can you use contribution reserving with non-concessional contributions?

The contribution reserving strategy can be used with non-concessional contributions. However, the process is quite different. The SMSF trustee must write to the ATO to request the reallocation, which may lead to greater scrutiny and a higher risk of rejection. Because there is no standard form to advise the ATO, the fund will likely receive an excess non-concessional determination before the reallocation is successfully processed. This can upset the trustee and incur additional accounting fees before it is rectified.
