Section 2 -- Required inputs and refusal catalogue

Required inputs

Minimum viable -- entity structure (sole trader / company / trust / partnership), whether client has employees, OTE per quarter (for employers), and voluntary contribution intent (for sole traders).

Recommended -- bank statements showing super fund debits, employee roster with OTE, TSB at 30 June prior year, taxable income for Division 293.

Ideal -- complete activity statement data, super fund member statements, s 290-150 notice copies, ATO online account showing contribution caps.

Refusal catalogue

R-AU-SG-1 -- Defined benefit funds. Trigger: client has a defined benefit fund. Message: "Defined benefit fund calculations are actuarially determined and out of scope. Escalate."

R-AU-SG-2 -- Constitutionally protected funds. Trigger: client has a constitutionally protected state fund. Message: "Out of scope. Escalate."

R-AU-SG-3 -- Family law splits. Trigger: super splitting in divorce. Message: "Family law superannuation splits require legal advice. Out of scope."

R-AU-SG-4 -- SGC penalty computation. Trigger: client has missed SG deadlines and asks about SGC. Message: "Super Guarantee Charge computation should be escalated to a qualified practitioner. SGC includes shortfall + 10% nominal interest + $20 per employee per quarter, and is NOT tax-deductible."

Section 4 -- Worked examples

Six bank statement classifications for a hypothetical Australian sole trader with 2 employees.

Example 1 -- Quarterly SG payment to employee's super fund

Input line: 28.10.2024 ; AUSTRALIAN SUPER ; DEBIT ; SG Q1 2024-25 EMPLOYEE A ; -2,300.00 ; AUD

Reasoning: Matches "AUSTRALIAN SUPER" (pattern 3.1). Amount $2,300 = $20,000 OTE x 11.5% SG. This is the Q1 (Jul-Sep) SG contribution for Employee A, paid by the 28 October deadline. Tax-deductible for the employer.

Classification: EXCLUDE -- SG contribution for employee. Tax-deductible business expense.

Example 2 -- Personal voluntary super contribution (sole trader)

Input line: 15.05.2025 ; BPAY HOSTPLUS ; DEBIT ; PERSONAL CONTRIBUTION ; -10,000.00 ; AUD

Reasoning: Matches "BPAY" + "HOSTPLUS" (pattern 3.2). Sole trader making a personal super contribution. Whether this is concessional (deductible) depends on whether the s 290-150 notice is lodged and acknowledged. If notice lodged: $10,000 concessional contribution, tax-deductible, taxed at 15% in the fund. If no notice: non-concessional, no deduction.

Classification: EXCLUDE -- personal super contribution. Deductibility depends on s 290-150 notice status. Flag: "Has the Notice of Intent to Claim a Deduction been lodged with the fund?"

Example 3 -- ATO Small Business Clearing House payment

Input line: 27.01.2025 ; ATO SUPER CLEARING HOUSE ; DEBIT ; SG Q2 ALL EMPLOYEES ; -4,600.00 ; AUD

Reasoning: Matches "ATO SUPER CLEARING HOUSE" (pattern 3.3). Small business paying SG for all employees via the ATO SBSCH. The clearing house distributes to each employee's nominated fund. Q2 (Oct-Dec) payment by 28 January deadline.

Classification: EXCLUDE -- SG contributions via SBSCH. Tax-deductible.

Example 4 -- OTE above maximum contribution base

Input line: 28.04.2025 ; REST SUPER ; DEBIT ; SG Q3 EMPLOYEE B ; -7,483.05 ; AUD

Reasoning: Matches "REST SUPER" (pattern 3.1). Amount $7,483.05 = $65,070 (max contribution base) x 11.5%. Employee B's OTE for Q3 exceeded $65,070, so SG is capped.

Classification: EXCLUDE -- SG contribution (capped at maximum contribution base).

Example 5 -- Sole trader asking about self-SG

Input line: No super fund debits found for the sole trader's own account.

Reasoning: Sole traders have NO SG obligation to themselves. Drawings are not salary. If the sole trader wants super, they must make voluntary personal contributions.

Classification: No SG payment expected for sole trader's own account. Recommend voluntary contribution strategy.

Example 6 -- ATO tax payment (NOT super)

Input line: 28.10.2024 ; ATO ; DEBIT ; IAS SEP QTR ; -3,500.00 ; AUD

Reasoning: Matches "ATO" + "IAS" (pattern 3.6). This is an Instalment Activity Statement (PAYG/GST) payment, NOT a super contribution.

Classification: EXCLUDE -- tax payment. NOT super.

---

Section 5 -- Tier 1 rules

Rule 1 -- SG formula

SG per quarter = min(Employee_OTE_for_quarter, $65,070) x 11.5%

No $450/month threshold (removed 1 July 2022). All employees eligible.

Rule 2 -- SG rate

2024-25: 11.5%. 2025-26 onwards: 12%.

Rule 3 -- Quarterly deadlines

Quarter	Period	Due
Q1	1 Jul - 30 Sep	28 October
Q2	1 Oct - 31 Dec	28 January
Q3	1 Jan - 31 Mar	28 April
Q4	1 Apr - 30 Jun	28 July

Late/missed: triggers Super Guarantee Charge (SGC). SGC is NOT tax-deductible.

Rule 4 -- Sole traders have NO SG obligation to themselves

Drawings are not salary. Only voluntary contributions. Company directors paying themselves a salary: YES SG applies (director is employee of company).

Rule 5 -- Concessional contributions cap

$30,000 (2024-25). Includes employer SG + salary sacrifice + personal deductible contributions (with s 290-150 notice). Excess included in assessable income at marginal rate (with 15% offset).

Rule 6 -- Carry-forward unused concessional cap

Available from 2018-19 onward, up to 5 prior years, IF TSB < $500,000 at 30 June prior year. If TSB >= $500,000: no carry-forward.

Rule 7 -- Non-concessional cap

$120,000 (2024-25). Bring-forward: $360,000 (3 years) if TSB < $1,660,000. TSB >= $1,900,000: nil cap.

Rule 8 -- s 290-150 notice (personal contribution deduction)

Must lodge Notice of Intent to Claim a Deduction with the super fund AND receive acknowledgement BEFORE the earlier of: lodging the tax return, or end of following financial year. If not lodged: contribution stays non-concessional, NO deduction.

Rule 9 -- Division 293 (additional 15% for high earners)

Div 293 income = taxable income + concessional contributions
If > $250,000: Div 293 tax = 15% x lesser of (concessional contributions, excess over $250,000)

Rule 10 -- Government co-contribution

Max $500. Income < $60,400. Matching rate: 50c per $1 of non-concessional contribution (max $1,000 contributed). Reduces above $45,400. Automatic upon tax return lodgement.

Section 6 -- Tier 2 catalogue

T2-1 -- Contractor vs employee for SG

Trigger: Client engages a contractor who may be principally for labour (SGAA s 12(3)). Issue: Multi-factor test required. SG may be triggered. Action: Flag for reviewer.

T2-2 -- Multiple employers exceeding concessional cap

Trigger: Individual has two employers both paying SG. Combined may exceed $30,000. Issue: Neither employer at fault. Individual bears excess contributions tax. Action: Flag for reviewer to assess salary sacrifice adjustment.

T2-3 -- Over-75 contributions

Trigger: Client aged 75+ wants to make voluntary contributions. Issue: Work test applies (40 hours in 30 consecutive days). Mandated employer SG has no age limit. Action: Flag for reviewer.

T2-4 -- Carry-forward with borderline TSB

Trigger: TSB close to $500,000 threshold. Issue: Carry-forward availability depends on exact TSB at 30 June. Action: Flag for reviewer to confirm TSB.

T2-5 -- s 290-150 notice deadline approaching

Trigger: Client made personal contributions but has not lodged notice. Issue: Missing the deadline is irreversible -- contribution stays non-concessional. Action: Urgent flag. Confirm notice status before lodging return.

Section 8 -- Bank statement reading guide

How super payments appear on Australian bank statements

Direct fund payments:

• Description: Fund name (e.g., "AUSTRALIAN SUPER", "HOSTPLUS", "REST SUPER")
• Timing: Quarterly (by 28th of month after quarter end) or more frequently
• Amount: SG amount per employee or personal contribution amount

BPAY payments:

• Description: "BPAY" + biller name or code
• Timing: Any time
• Amount: SG or personal contribution

ATO Super Clearing House:

• Description: "ATO SUPER", "ATO CLEARING HOUSE", "SBSCH"
• Timing: Quarterly
• Amount: Combined SG for all employees

Key identification tips:

1. Super fund names are the most reliable identifier
2. BPAY to a super fund shows biller code -- cross-reference with fund
3. ATO SBSCH is a single payment covering all employees
4. Sole trader personal contributions look like any other fund payment -- context required
5. SGC payments go to ATO, not to the fund
6. Payday Super (from 1 July 2026) will change timing to each payday

---

Section 9 -- Onboarding fallback

If the client provides only a bank statement:

1. Scan for super fund debits -- match against fund names in Section 3
2. Identify SG vs personal contributions -- quarterly amounts aligned with deadlines = likely SG; ad hoc amounts = likely personal
3. Check for ATO SBSCH -- indicates employer using clearing house
4. Sum quarterly SG payments -- compare against expected OTE x 11.5% to verify completeness
5. Flag: "Super contribution classification derived from bank statement patterns. Employee OTE, s 290-150 notice status, and TSB have not been independently verified. Reviewer must confirm before tax return lodgement."

Section 10 -- Reference material

Key rates and thresholds (2024-25)

Item	Value
SG rate	11.5%
Max contribution base (quarterly)	$65,070
Maximum SG per quarter	$7,483.05
Concessional cap	$30,000
Non-concessional cap	$120,000
Bring-forward (3 years)	$360,000
Div 293 threshold	$250,000
Co-contribution max	$500
Co-contribution lower threshold	$45,400
Co-contribution upper threshold	$60,400
LISTO threshold	$37,000
Spouse offset max	$540
Transfer balance cap	$1,900,000

LISTO (Low Income Super Tax Offset)

Adjusted taxable income <= $37,000: 15% of concessional contributions, max $500. Paid directly into super fund by ATO.

Spouse contribution tax offset

Max $540 (18% of $3,000). Full offset if spouse income <= $37,000. Nil if spouse income >= $40,000.

Test suite

Test 1: Employee OTE $20,000/quarter, 2024-25. -> SG = $2,300.

Test 2: Employee OTE $80,000/quarter. -> SG = $7,483.05 (capped).

Test 3: Sole trader contributes $25,000, lodges s 290-150. TSB $200,000. -> $25,000 concessional. Deduction $25,000. Within cap.

Test 4: Taxable income $260,000, concessional $30,000. -> Div 293 income $290,000. Div 293 tax = 15% x $30,000 = $4,500.

Test 5: TSB $400,000. Unused cap: $5,000 (2021-22) + $10,000 (2022-23) + $15,000 (2023-24). -> Available cap = $60,000.

Test 6: Income $50,000, non-concessional $1,000. -> Co-contribution = $346.68.

Test 7: $5,000 to spouse's fund, spouse income $36,000. -> Offset = $540.

Test 8: Sole trader asks about SG to self. -> $0. No obligation. Advise voluntary contributions.

Prohibitions

• NEVER tell a sole trader they must pay SG to themselves
• NEVER apply 12% rate to 2024-25 (rate is 11.5%)
• NEVER ignore maximum contribution base ($65,070/quarter)
• NEVER allow deduction claim without confirmed s 290-150 notice
• NEVER apply carry-forward if TSB >= $500,000
• NEVER present figures as definitive
• NEVER compute SGC penalties without escalating
• NEVER advise on defined benefit or constitutionally protected funds
