Superannuation Strategy — Dean & Kara (2025-26)

Strategy to optimise super contributions using salary sacrifice, contribution splitting, and the spouse contribution tax offset.

Incomes & Tax Brackets

Person Salary Marginal Rate
Dean $85,000 30%
Kara $31,000 16%

Dean's employer SG (12%): ~$10,200/yr (auto)

Concessional Contributions Cap

Item Amount
Annual concessional cap (2025-26) $30,000
Dean's employer SG used $10,200
Dean's remaining headroom $19,800

Going over $30,000 triggers extra tax.

Scenario: $10,000 Salary Sacrifice

Instead of receiving $10,000 as income (taxed at 30%), it goes into super (taxed at 15%).

Without With
Tax on $10k $3,000 (30%) $1,500 (15%)
Tax saving $1,500
Take-home reduction ~$7,000
Amount landing in super $8,500

Contribution Splitting

After financial year end, Dean can split up to 85% of concessional contributions into Kara's super.

  • 85% of $10,000 = $8,500 moves to Kara's account
  • Tax saving already happened on Dean's end
  • Counts against Dean's caps, not Kara's

Why split: evens up retirement balances, grows Kara's super faster, can help with Age Pension asset testing.

Spouse Contribution Tax Offset

Dean contributes $3,000 from after-tax pay into Kara's super via BPAY → gets 18% tax offset (up to $540/yr).

  • Kara earns $31,000 → under $37,000 threshold → qualifies for full offset
  • Separate to salary sacrifice — just a bank transfer into her super
  • Essentially an 18% instant return on $3,000

Full Year Summary ($10k sacrifice + $3k spouse)

Action Benefit
$10k salary sacrifice (30% → 15%) $1,500 tax saved
$3k spouse contribution offset $540 back at tax time
Total annual benefit $2,040
Extra flowing into super ~$11,500

If Dean Maxes Headroom ($19,800 sacrifice)

Item Amount
Tax saving (30% → 15%) ~$2,970
+ Spouse offset $540
Total benefit ~$3,510

Key Rules

  • Salary sacrifice goes into your own super only
  • Contribution splitting is the workaround (done after year end through your fund)
  • Total concessional must stay under $30,000/yr
  • Kara must be under 60 (or 60–65 not retired) to receive split
  • Kara's total super balance must be under $2 million
  • Unused concessional cap can be carried forward if balance < $500,000
