A Self-Managed Superannuation Fund (SMSF) gives members direct control over their retirement savings and investment decisions. Unlike retail or industry super funds, SMSF members act as trustees and are personally responsible for compliance with superannuation law. Understanding contribution rules is critical for SMSF trustees. Concessional (before-tax) contributions include employer Super Guarantee payments, salary sacrifice, and personal deductible contributions — all subject to a combined cap of $27,500 per year (2023-24). Non-concessional (after-tax) contributions are capped at $110,000 per year, but eligible individuals with a total super balance below $330,000 can bring forward up to three years of non-concessional contributions, contributing up to $330,000 in a single year. Contribution eligibility depends on age and work test requirements. Your Total Super Balance (TSB) at 30 June of the previous year determines your access to the bring-forward arrangement and non-concessional contributions. Excess contributions face punitive tax treatment: excess concessional contributions are included in assessable income (taxed at marginal rate) with only a 15% offset, while excess non-concessional contributions are taxed at 47% unless you choose to withdraw them (plus notional earnings). SMSF trustees must ensure contributions are received before 30 June to count for the relevant financial year.
Concessional Contribution Room = $27,500 - (SG + Salary Sacrifice + Personal Deductible); Non-Concessional Cap = $110,000 (or $330,000 over 3 years if TSB < $330,000); Excess Concessional Tax = (Excess Amount × Marginal Rate) - 15% Offset
- 1Calculate your total concessional contributions for the year: employer SG (11.5% in 2024-25) plus any salary sacrifice plus personal deductible contributions (where a Notice of Intent to Claim Deduction is lodged with the fund).
- 2Compare total concessional contributions to the $27,500 cap. If below the cap, you may have unused concessional cap space that can be carried forward under the catch-up contribution rules (if TSB < $500,000).
- 3For non-concessional contributions, check your Total Super Balance (TSB) as at 30 June of the prior year. If TSB is $1.9M or more, no non-concessional contributions are permitted.
- 4If TSB is below $330,000, you can trigger the bring-forward rule to contribute up to $330,000 in one year (or $220,000 if TSB $220,000–$330,000, or $110,000 if TSB is $330,000–$1.68M).
- 5Ensure contributions are received (cleared into the SMSF bank account) before 30 June for them to count in the current financial year.
- 6Monitor the SMSF's annual return requirements: contributions must be reported to the ATO in the fund's SMSF annual return, and member accounts must show contributions correctly allocated.
- 7If excess contributions are identified, act promptly — the ATO issues an excess concessional contributions determination or excess non-concessional contributions tax assessment within 12 months of the annual return being processed.
Close to the cap — any additional deductible personal contribution must not exceed $700.
SG $13,800 + salary sacrifice $13,000 = $26,800. Under the $27,500 cap by $700. No excess concessional contributions tax applies. The $700 remaining room could be used for a personal deductible contribution before year-end.
TSB below $330,000 allows the full 3-year bring-forward.
With TSB under $330,000, the member can contribute the full 3-year bring-forward amount of $330,000 in a single year. No further NCC can be made in the following two financial years without triggering excess NCC tax.
Excess concessional contributions are taxed at marginal rate minus the 15% contributions tax offset.
The $3,500 excess above the $27,500 cap is included in assessable income. At 37% marginal rate, tax is $1,295. A 15% offset ($525) applies. Net extra tax: $770. This is in addition to the 15% contributions tax already paid by the fund.
Once TSB reaches $1.9M, no NCC can be made.
Individuals with a TSB of $1.9M or more (the general transfer balance cap) cannot make non-concessional contributions. Any NCC made in this circumstance would be excess NCC, taxed at 47% unless elected to be released.

Contributions for Members Over 75
In the Smsf Contributions, this scenario requires additional caution when interpreting smsf contributions results. The standard formula may not fully account for all factors present in this edge case, and supplementary analysis or expert consultation may be warranted. Professional best practice involves documenting assumptions, running sensitivity analyses, and cross-referencing results with alternative methods when smsf contributions calculations fall into non-standard territory.
Spouse Contributions
A tax offset of up to $540 is available for contributions up to $3,000 made to a low-income spouse's account (income below $37,000). The contributing spouse must have sufficient income or meet eligibility conditions."}.

What is the difference between concessional and non-concessional contributions?
Concessional contributions are made from before-tax income and include employer SG, salary sacrifice, and personal deductible contributions. They are taxed at 15% inside the fund. Non-concessional contributions are made from after-tax income and receive no further tax deduction. They are not taxed on entry into the fund. This is particularly important in the context of smsf contributions calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise smsf contributions computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the catch-up concessional contribution rule?
If your Total Super Balance is below $500,000 at 30 June of the prior year, you can carry forward unused concessional cap space from the previous 5 years and contribute the accumulated unused amounts in a single year. This is particularly useful for those who had low incomes or career breaks in prior years.
How does the bring-forward rule work for NCC?
If you are under 75 and your TSB is below $1.68M, you may be able to use the bring-forward arrangement to contribute more than the annual NCC cap of $110,000. The maximum bring-forward amount (up to $330,000 over 3 years) depends on your TSB, with higher balances receiving reduced or no bring-forward access.
Does the work test still apply?
From 1 July 2022, the work test was relaxed. Individuals aged 67–74 can make voluntary contributions (concessional and non-concessional) without meeting the work test if their TSB is below $300,000 and they met the work test in the prior year — this was the work test exemption. From 2023, the work test for concessional contributions was further relaxed.
What happens if I accidentally exceed the concessional cap?
The ATO will issue an Excess Concessional Contributions determination. You have the option to leave the excess in the fund (it will be taxed at your marginal rate minus the 15% offset) or withdraw the excess. Withdrawing does not attract the Division 293 penalty but the excess amount is still included in your income.
What is the Total Super Balance and why does it matter?
Your Total Super Balance (TSB) is the sum of all your superannuation interests across all funds at 30 June each year. It determines access to the NCC bring-forward, catch-up concessional contributions, and the government co-contribution. Once your TSB reaches the general transfer balance cap ($1.9M in 2023-24), many contribution strategies are restricted.
Are there contribution rules for SMSF members over 75?
From 1 July 2022, individuals aged 75 and over can receive mandatory employer SG contributions and downsizer contributions, but can no longer make voluntary concessional or non-concessional contributions. The downsizer contribution scheme allows those over 55 to contribute up to $300,000 from the sale of a primary residence. This is particularly important in the context of smsf contributions calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise smsf contributions computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is a downsizer contribution?
A downsizer contribution allows individuals 55 and over to contribute up to $300,000 (or $600,000 per couple) from the sale of their principal residence into super. Downsizer contributions are non-concessional but do not count against the NCC cap or the bring-forward limit. They can be made regardless of TSB. This is particularly important in the context of smsf contributions calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise smsf contributions computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Pro Tip
If you have unused concessional contributions cap space from prior years (and TSB under $500,000), consider catch-up contributions in a high-income year. A single large deductible contribution can substantially reduce tax while building super.
