General reference only. This skill is general tax/accounting reference material for AI-assisted workflows. It has not been reviewed for any specific person's facts, documents, elections, deadlines, residency, filing status, or local procedures. Do not rely on it to file, pay, amend, or take a tax position without review by a qualified professional in the relevant jurisdiction.

Regime change at 1 July 2026 (Payday Super). SG timing is determined by WHEN earnings are PAID, not when the work was done. Earnings paid from 1 July 2026: payday super rules (SG received by the fund within 7 business days of each payday). Earnings paid up to 30 June 2026: old quarterly rules (final quarterly deadline was 28 July 2026 for the June 2026 quarter). Both regimes appear in 2026 bank statements -- classify by payment date.

Select the income year before calculating

This guide covers 2025–26 contribution reconciliation and 2026–27 payday SG. Ask for the requested year and fund receipt records; return that year in the output.

For the 2025–26 return-assembly branch, reconcile employer, salary-sacrifice and personal contributions received by the fund during 1 July 2025 to 30 June 2026. Use the $30,000 standard concessional cap, plus eligible carry-forward amounts where the prior 30 June total super balance was less than $500,000. Establish a valid acknowledged personal deduction notice before including a deduction, and test Division 293 using its full income definition. Employer SG is 12% on eligible ordinary time earnings, subject to the 2025–26 maximum contribution base and employment rules; quarterly due dates apply. Do not apply the later payday deadlines or $32,500 cap to this branch. Return the reconciled deduction and cap position to the ITR, then stop this branch.

The remaining payday calculations and indexed figures below concern 2026–27. ATO super guarantee rates; ITAA 1997 s 290-170.

Required inputs

Minimum viable -- entity structure (sole trader / company / trust / partnership), whether client has employees, pay frequency and payday dates, qualifying earnings per payday (for employers), and voluntary contribution intent (for sole traders).

Recommended -- bank statements showing super fund debits, payroll register with per-payday qualifying earnings and YTD totals, TSB at 30 June prior year, taxable income for Division 293.

Ideal -- complete STP reporting data, super fund member statements showing receipt dates, s 290-170 notice copies, ATO online account showing contribution caps.

Section 4 -- Worked examples

Six classifications for a hypothetical Australian employer with 2 employees, fortnightly payroll, during 2026-27.

Example 1 -- Payday super contribution following a fortnightly pay run

Input line: 24.07.2026 ; AUSTRALIAN SUPER ; DEBIT ; SUPER PPE 17/07 EMPLOYEE A ; -480.00 ; AUD

Reasoning: Matches "AUSTRALIAN SUPER" (pattern 3.1). Payday was Friday 17 July 2026; $480.00 = $4,000 qualifying earnings x 12%. Fund receipt on 24 July is 5 business days after payday -- inside the 7-business-day window. Tax-deductible for the employer.

Classification: EXCLUDE -- SG contribution for employee, on time under payday super. Tax-deductible business expense.

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

Input line: 15.05.2027 ; 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 290-170 notice is lodged and acknowledged. If notice lodged: $10,000 concessional contribution, tax-deductible, taxed at 15% in the fund, counts toward the $32,500 cap. If no notice: non-concessional, no deduction.

Classification: EXCLUDE -- personal super contribution. Deductibility depends on s 290-170 notice status. Flag: "Has the Notice of Intent to Claim a Deduction been lodged with the fund?"

Example 3 -- Commercial clearing house payment (SBSCH is gone)

Input line: 21.08.2026 ; SUPERCHOICE CLEARING ; DEBIT ; SUPER PPE 14/08 ALL EMPLOYEES ; -960.00 ; AUD

Reasoning: Commercial clearing house debit covering both employees for the 14 August payday (pattern 3.3). The ATO Small Business Super Clearing House closed permanently on 1 July 2026, so any post-June-2026 clearing house payment is a commercial provider or payroll-software-integrated service. On-time test = fund receipt within 7 business days of the 14 August payday, NOT the clearing house debit date -- flag if fund receipt confirmation is unavailable.

Classification: EXCLUDE -- SG contributions via commercial clearing house. Tax-deductible. Flag fund-receipt timing for confirmation.

Example 4 -- Annual maximum contribution base reached

Input line: (no super debit present for Employee B for the 9 April 2027 payday)

Reasoning: Employee B's year-to-date qualifying earnings passed $270,830 in March 2027 (large bonus in Q3). Under the ANNUAL maximum contribution base, once YTD qualifying earnings for 2026-27 reach $270,830, no further SG is required for the rest of the financial year. Maximum SG for the year = $32,499.60. Note front-loaded income exhausts the cap early -- this replaces the old per-quarter cap logic entirely.

Classification: No SG expected for Employee B for remaining 2026-27 paydays. Verify YTD qualifying earnings ledger supports the cutoff.

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: 28.10.2026 ; 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. (Quarterly IAS/BAS cycles continue -- only SG moved to payday timing.)

Classification: EXCLUDE -- tax payment. NOT super.

Section 5 -- Tier 1 rules

Rule 1 -- SG formula (payday super)

• SG formula (payday super) — remaining_base = max(0, $270,830 - YTD_qualifying_earnings_before_this_payday) SG per payday = 12% x min(Qualifying_earnings_paid_this_payday, remaining_base). SG applies only to the first $270,830 of qualifying earnings paid in the financial year -- the payday that crosses the base attracts SG only on the portion beneath it, and later paydays attract none. Annual maximum SG per employee: exactly $32,499.60. No $450/month threshold (removed 1 July 2022). Test employment eligibility separately. The removal of the $450 monthly threshold did not remove exclusions, including employees under 18 who do not work more than 30 hours in a week and the separate private/domestic work exclusion where hours do not exceed 30 in a week. (SGAA 1992 ss 27–29 (https://www.ato.gov.au/law/view/document?docid=PAC/19920111/27))

Rule 2 -- SG rate

• SG rate — 2024-25: 11.5%. 2025-26 onwards: 12% (terminal rate). %

Rule 3 -- Payment deadline (earnings paid from 1 July 2026)

• Payment deadline (earnings paid from 1 July 2026) — A contribution is on time only if it is received by the employee's super fund, with the information needed to allocate it to the member account, within 7 business days after payday (the "QE day"). - Business day = any day except Saturday, Sunday, or a public holiday applying to the WHOLE of any Australian state or territory. A territory-wide holiday anywhere in Australia extends the deadline for ALL employers; part-of-state holidays do not. - New employee (or new fund): first contribution due within 20 business days of the relevant QE day; later paydays revert to 7. If the extended date overlaps the next payday's deadline, the later contribution inherits the extended date. - Out-of-cycle payments (e.g. bonuses, per LI 2026/20): SG rides with the next regular payday's 7-business-day deadline. - Exceptional circumstances (ATO class determination, e.g. natural disasters): later of 20 business days after the QE day or 20 business days after the determination. - Funds must allocate or return contributions within 3 business days (down from 20). Legacy: earnings paid up to 30 June 2026 keep the quarterly deadlines (28 Oct / 28 Jan / 28 Apr / 28 Jul); the final quarterly deadline was 28 July 2026.

Rule 4 -- Maximum contribution base is ANNUAL from 2026-27

• Maximum contribution base is ANNUAL from 2026-27 — $270,830 of qualifying earnings for 2026-27 (formula: concessional cap x 100 / 12, rounded down to nearest $10 = $32,500 x 100 / 12). Applied on a year-to-date basis per the Rule 1 formula: SG is payable on qualifying earnings up to the base, the crossing payday is prorated, and nothing is payable on earnings beyond it. Maximum SG per employee per year: $32,499.60. (Last quarterly MCB: $62,500/quarter in 2025-26.)

Rule 5 -- Sole traders have NO SG obligation to themselves

• Sole traders have NO SG obligation to themselves — - Sole trader / director SG obligation — Drawings are not salary. Only voluntary contributions. Company directors paying themselves a salary: YES SG applies (director is employee of company). (Rule 4)

Rule 6 -- Concessional contributions cap

• Concessional contributions cap — $32,500 (2026-27; indexed up from $30,000 on 1 July 2026). Includes employer SG + salary sacrifice + personal deductible contributions (with s 290-170 notice). Excess included in assessable income at marginal rate (with 15% offset). AUD

Rule 7 -- Carry-forward unused concessional cap

• Carry-forward unused concessional cap — Up to 5 prior years' unused cap, IF TSB < $500,000 at 30 June prior year (threshold fixed in legislation, not indexed). If TSB >= $500,000: no carry-forward.

Rule 8 -- Non-concessional cap

• Non-concessional cap — $130,000 (2026-27; 4 x concessional cap). Bring-forward tiers by TSB at 30 June 2026: < $1.84m -> $390,000 over 3 years; $1.84m to < $1.97m -> $260,000 over 2 years; $1.97m to < $2.1m -> $130,000 (no bring-forward); >= $2.1m -> nil. AUD

Rule 9 -- s 290-170 notice (personal contribution deduction)

• s 290-170 notice requirement — 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 8)

Rule 10 -- Division 293 (additional 15% for high earners)

• Division 293 — Division 293 income is income for surcharge purposes excluding reportable super contributions, plus applicable low-tax contributions. Include the relevant reportable fringe benefits and net investment losses; apply statutory exclusions, including assessable FHSS released amounts. Tax is 15% of the lesser of low-tax contributions and the positive excess over $250,000. Exclude excess concessional contributions from low-tax contributions. Example: taxable income $230,000, reportable fringe benefits $20,000 and applicable low-tax contributions $25,000, with no other adjustments, give $275,000 for the threshold test. Division 293 tax is 15% of $25,000 = $3,750. (ITAA 1997 ss 293-20 and 293-25 (https://www.ato.gov.au/law/view/document?docid=PAC/19970038/293-20))

Rule 11 -- Redesigned SGC (QE days from 1 July 2026)

• Redesigned SGC (QE days from 1 July 2026) — ATO-assessed per payday (no SG statement is lodged; ATO matches STP against fund reporting). Components: 1. Final SG shortfall -- unpaid SG on qualifying earnings at 12% 2. Notional earnings -- GIC-rate interest on the shortfall, compounding daily from the day after the deadline 3. Administrative uplift -- starts at 60% of (shortfall + notional earnings); reduced 20 points for a clean 2-year history and up to 40 points for voluntary disclosure (0% if disclosed within 30 days with clean history) 4. Choice loading -- 25% of contributions where choice-of-fund rules breached, capped at $1,200 per notice period Payment due the day the assessment is made. Unpaid 28 days after assessment -> Notice to Pay -> late payment penalty of 25% or 50% of unpaid SGC. The new SGC is tax-deductible (all four components); GIC on late SGC and the late payment penalty are not, and old-regime SGC (quarters before 1 July 2026) remains non-deductible. First-year approach: PCG 2026/1. (PCG 2026/1)

Personal deduction notice validity

• Personal deduction notice validity — Before claiming a personal contribution deduction, verify the notice was valid when given and acknowledged by the fund. Check membership, whether the fund still held the contribution, any rollover/withdrawal, commencement of an income stream and contribution-splitting application. Check the deduction eligibility and age/work-test rules separately. The deadline alone does not establish validity. (ITAA 1997 s 290-170 (https://www.ato.gov.au/law/view/document?docid=PAC/19970038/290-170))

Section 8 -- Bank statement reading guide

How super payments appear on Australian bank statements (2026-27)

Direct fund payments:

• Description: Fund name (e.g., "AUSTRALIAN SUPER", "HOSTPLUS", "REST SUPER")
• Timing: Tracks the pay cycle -- weekly/fortnightly/monthly debits within days of each payday
• Amount: 12% of that payday's qualifying earnings per employee, or personal contribution amount

BPAY payments:

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

Clearing house payments:

• Description: Commercial clearing house or payroll software name (SBSCH references only on pre-July-2026 statements)
• Timing: Within days of each payday
• 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. Frequent small super debits aligned to paydays = payday super normal, not an anomaly
4. Quarterly-sized lumps after June 2026 (other than the final 28 July 2026 payment) = possible late-regime confusion; flag
5. Sole trader personal contributions look like any other fund payment -- context required
6. SGC payments go to ATO, not to the fund
7. "ATO SBSCH" on a statement dated after June 2026 = returned payment or misclassification; investigate

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 -- payday-aligned amounts = likely SG; ad hoc amounts = likely personal
3. Check debit cadence against pay cycle -- SG debits should follow every payday from July 2026
4. Sum SG debits per employee -- compare against expected qualifying earnings x 12% YTD to verify completeness
5. Flag: "Super contribution classification derived from bank statement patterns. Fund receipt dates, qualifying earnings, s 290-170 notice status, and TSB have not been independently verified. Reviewer must confirm before tax return lodgement."

Test suite

Test 1: Employee qualifying earnings $4,000, fortnightly payday, 2026-27. -> SG = $480.00 per payday, fund receipt within 7 business days.

Test 2: Employee YTD qualifying earnings $268,000 before a $10,000 payday in March 2027. -> Crossing payday SG = 12% x min($10,000, $270,830 - $268,000) = 12% x $2,830 = $339.60. All later 2026-27 paydays: $0. Year SG total = exactly $32,499.60.

Test 3: Sole trader contributes $25,000, lodges s 290-150. TSB $200,000. -> $25,000 concessional. Deduction $25,000. Within $32,500 cap.

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 (2023-24) + $10,000 (2024-25) + $15,000 (2025-26). -> Available 2026-27 cap = $32,500 + $30,000 = $62,500.

Test 6: Income $45,000, non-concessional contribution $1,000. -> Co-contribution = $500 (income below $49,293 lower threshold).

Test 7: $5,000 to spouse's fund, spouse income $36,000, spouse TSB $300,000. -> Offset = $540.

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

Test 9: Payday Friday 4 Sep 2026; contribution received by fund Wednesday 16 Sep 2026 (8 business days). -> LATE. ATO-assessed SGC per Rule 11; new-regime SGC deductible.

Test 10: New employee starts, first payday 10 Jul 2026, no fund details yet. -> First contribution due within 20 business days of the QE day; subsequent paydays revert to 7.

Prohibitions
