Concessional super contributions are one of the most reliable tax planning levers in the Australian system — but they reduce business tax only when company structure, director income, Division 293, Division 296 and timing all line up. For company- and trust-structured business owners, the question every year is not can I contribute, but should I, through which entity, and by when.
This guide from Trinity Accounting Practice walks through the six variables that change the answer for business owners before 30 June 2026, the three timing traps that quietly cause directors to lose the deduction, and how Division 296 reshapes the decision from 1 July 2026.
What concessional contributions actually reduce — and for whom
A concessional contribution is a before-tax contribution taxed at 15% inside the super fund. It can reduce taxable income for the entity that contributes — and the choice of entity is where the after-tax outcome is really decided.
Three contribution pathways are concessional:
- Employer Superannuation Guarantee (SG) — currently 12% from 1 July 2025, paid by the company.
- Salary sacrifice — directed from pre-tax wages to super.
- Personal deductible contributions under s290-150 ITAA 1997 — made from after-tax money and claimed back via a Notice of Intent.
The concessional cap for 2025–26 is $30,000, across all three pathways combined. The deduction attaches to the entity that contributed — a company-paid contribution reduces company tax; a personal deductible contribution reduces the individual’s tax. The choice changes the after-tax outcome by a meaningful margin, and it is where most business owners stop short of the optimum.
The six variables that change the answer for business owners
1. Company tax rate (25% or 30%)
A $30,000 company-paid contribution saves $7,500 at the 25% base rate or $9,000 at the 30% rate. A personal deductible contribution from a director on the 45% marginal rate saves roughly $9,000 after the 15% contributions tax inside super. The “best entity” depends on the relative rates — and at the very top marginal rate, the personal pathway often wins.
2. Director’s personal marginal rate
The bigger the gap between the director’s marginal rate and the 15% contributions tax, the more useful super is as a tax shelter. At 45%, the spread is 30 cents on the dollar. At 32%, only 17. At 19% (a low-income year), the spread is just 4 cents — and the lock-up of capital until preservation age often is not worth it.
3. Total Super Balance (TSB) and Division 296 proximity
The director’s TSB on 30 June of the previous year sets the decision frame:
- Under $500,000: eligible for carry-forward unused concessional cap from up to five prior years — often a much larger window than the current-year cap alone.
- $500,000 – $3 million: standard rules apply.
- Approaching $3 million: Division 296 territory from 1 July 2026 — see Section 4 below.
4. Division 293 ($250,000 combined income)
Where the sum of taxable income and concessional contributions exceeds $250,000, Division 293 adds another 15% tax on the excess concessional contributions — effectively a 30% rate inside super, not 15%. For high-income directors, the arbitrage against personal marginal rate narrows but rarely disappears entirely. It just needs to be in the model.
5. Borrowing capacity
A concessional contribution reduces this year’s taxable income, which reduces the assessable income lenders use for serviceability. If you are about to apply for a commercial property loan, business finance refinance, or home loan, the tax saving may be offset by a smaller approved borrowing — sometimes by a much larger margin. Time the contribution around the application, not against it.
6. Cash flow and franking position
A concessional contribution permanently removes capital from the business and locks it inside super until preservation age. For a company sitting on retained profits that could otherwise be paid as fully franked dividends, the comparison is not always “deduction vs no deduction” — sometimes it is “deduction at 25% vs franked dividend with franking credit refund.” The franked dividend route often wins for shareholders on lower marginal rates.
Who claims it — company, trust or individual?
Company-claimed deduction
The company pays super to the director’s complying fund as an employer contribution under s290-60. The deduction applies at the company tax rate (25% or 30%). No Notice of Intent is required. The contribution must satisfy SG rules and the “reasonable remuneration” test — broadly, the contribution must be commercially reasonable for the role.
Personal deductible contribution (s290-150)
The director contributes from already-received salary, dividends or distributions. The deduction applies at the director’s personal marginal rate — typically higher than the company rate. A valid Notice of Intent must be lodged with the fund and acknowledged in writing before the director lodges their tax return. This path suits directors whose personal marginal rate clearly exceeds the company rate, or where retained profits are not available.
Trust-distributed then personally contributed
Trust-structured owners often run a three-step sequence: the trust distributes income to a beneficiary, the beneficiary makes a personal deductible contribution, and the beneficiary lodges a Notice of Intent. Three things must align: the trust distribution resolution before 30 June, the contribution receipt by the fund before 30 June, and the Notice of Intent before the beneficiary’s tax return. This pathway has multiple failure modes and is the one we most often see go wrong without specialist coordination.
How Division 296 changes the calculation from 1 July 2026
Division 296 imposes an extra 15% tax on the earnings attributable to the portion of an individual’s TSB above $3 million (with an additional 10%, for a total of 30%, on the portion above $10 million). The $3 million threshold indexes in $150,000 increments to CPI.
For directors well below $3 million, the analysis runs as it always has. Around $2.5 million is where the conversation shifts: a $30,000 contribution made in 2025–26 will sit in the year-end TSB measured for the 2026–27 Division 296 calculation. For directors close to the threshold, contributions can push exposure across the line that was not previously there.
Above $3 million, each new dollar of concessional contribution generates future earnings that fall within the Division 296 regime, not the 15% concessional environment. The strategic question genuinely inverts — and the CGT cap contribution under s292-100 (for business sale proceeds) becomes a more relevant lever than the standard concessional cap, because it sits outside it.
The three timing traps that cost business owners the deduction
Trap 1: Fund cut-off dates are not 30 June
Most large super funds require contributions by 20–23 June to guarantee allocation before 30 June. A contribution received after the fund’s internal cut-off may be allocated to the following financial year — and any carry-forward cap you were intending to use evaporates unused. Confirm receipt dates with the fund, not payment dates from your bank.
Trap 2: The quarterly SG payment lag (for FY26 only)
SG for the April–June 2026 quarter is legally payable by 28 July 2026. A company paying Q4 SG in late June 2026 may find the contribution does not arrive at the fund until July — counting toward the FY27 cap, not FY26. This is the last year this trap operates: payday super from 1 July 2026 will require SG to be paid on the same cadence as wages, eliminating the lag entirely from FY27 onwards.
Trap 3: BPAY and electronic transfer float
BPAY typically takes 2–3 business days to clear to the fund. EFTs vary by bank. The practical rule is to initiate any 30 June contribution by mid-June at the latest, and to use direct EFT into the fund’s nominated bank account where possible. Allocate, do not assume — and ask the fund to confirm receipt in writing.
Notice of Intent — where personal deductible contributions quietly fail
A personal deductible contribution becomes deductible only when a valid Notice of Intent under s290-170 is lodged with the fund and acknowledged in writing before the tax return is lodged. The Notice fails when:
- The director has already rolled the contribution to another fund.
- The director has already withdrawn any part of the contribution — including by commencing a pension.
- The director has ceased to be a member of the fund.
- The Notice is lodged after the tax return.
None of these are recoverable retrospectively. The contribution reclassifies as non-concessional, counts against the $120,000 non-concessional cap, and the deduction is lost. The practical action is to lodge the Notice as early as possible — many of our directors lodge in July, not after lodgement season, to avoid acknowledgement delays.
When a concessional contribution is the wrong move
The contribution reduces tax in the abstract, but five scenarios produce a worse outcome than paying the tax and retaining capital in the business:
- You have an active borrowing application. Reduced assessable income lowers serviceability — sometimes by more than the tax saving.
- Your TSB is approaching or above $3 million. Division 296 from 1 July 2026 extends the decision horizon beyond the current year.
- Your marginal rate is below 30%. The arbitrage against the 15% contributions tax is too thin to justify locking capital until preservation age.
- Your business is carrying tax losses. A deduction offsets carry-forward losses you would otherwise use later.
- You are about to exceed the cap. Amounts over the cap are taxed at your marginal rate with limited offset — a planned tax saving becomes a tax penalty.
A Trinity insight from 22 years in practice
The single most common mistake we see is the late-June scramble: director rings on 26 June, fund receives the money on 2 July, and the contribution counts in the wrong year. We avoid it by running the concessional contribution conversation at the May year-end planning meeting, not the last week of June. The cap is not an emergency — but the timing is. Plan it once, in May; execute it cleanly by mid-June.
Payday super from 1 July 2026 — what changes next year
From 1 July 2026, employer SG must be paid contemporaneously with wages, not quarterly. The Q4 timing trap disappears, the SG cash flow profile becomes smoother across the year, and the strategic focus for year-end contributions shifts almost entirely to voluntary top-ups — salary sacrifice and personal deductible contributions — rather than gaming the SG payment date. SME clients will hear from us individually about payroll configuration well before 1 July 2026.
What this means for you
- If you are a company director under $500,000 TSB: the carry-forward cap may give you a much larger usable contribution than $30,000 this year. Model it.
- If your personal marginal rate is 37–45%: the personal deductible contribution pathway is often more efficient than the company-paid route. Coordinate the Notice of Intent.
- If your TSB is between $2.5 million and $3 million: Division 296 modelling should drive the decision. The right move may be smaller contributions, not larger.
- If you are about to borrow: defer the contribution decision until the loan is approved. The tax saving rarely outweighs the borrowing-capacity hit.
- If you operate through a trust: the trust-distribute-then-personally-contribute pathway needs three resolutions to line up. Do not run it last minute.
How Trinity can help
Trinity Accounting Practice runs the concessional contribution decision against each client’s full tax position — company tax rate, personal marginal rate, TSB, Division 293, Division 296 proximity, borrowing pipeline, and cash flow — at the May year-end planning meeting. We coordinate the Notice of Intent, confirm fund receipt timing, and document the position for the client file. Where the answer is “this year, no,” we record that and re-test next year. The contribution decision is one of the simplest annual planning moves in the Australian system — but only when it is made with the full context in front of you.
