SOPHIE EXPLAINS: Salary Sacrifice 2026 – Why You're Still $1,500 Ahead

▶

If you earn $80,000, sacrificing just $10,000 of salary into super in 2026–27 can leave you roughly $1,500 richer after tax every single year, because that $10,000 is taxed at 15% inside super instead of around 30% at your marginal rate.

The number that matters

32.5K — the 2026–27 concessional contributions cap in AUD, including employer SG and salary sacrifice, which defines the maximum “low‑tax zone” for super contributions each year. — First Super/ATO, 2026–27

How it quietly costs you

Mechanism: tax cut narrows (but doesn’t erase) the salary sacrifice advantage

• ATO confirms that salary sacrifice contributions to a complying super fund are taxed at 15% as concessional contributions, which is generally lower than your marginal tax rate.
• From 1 July 2026, the lowest personal income tax rate falls from 16% to 15% for incomes between $18,201 and $45,000, slightly reducing the gap between marginal tax and the 15% super tax for lower‑income workers.
• Yet industry guidance notes that salary sacrifice is particularly attractive once your annual income is above $45,000 and your marginal tax rate is 30% or more, because you are swapping ~30% marginal tax for 15% contributions tax.

Quantified impact in 2026–27

Using typical 2026–27 settings:

• Concessional cap: $32,500 including employer SG and salary sacrifice.
• Employer SG: 12% of ordinary time earnings (e.g., $9,600 on an $80,000 salary).

Example — worker on $80,000:

• Employer SG: $9,600 (12% of $80,000), taxed at 15% in super.
• Available concessional space for salary sacrifice: $32,500 – $9,600 = $22,900.
• If they sacrifice $10,000:
• As salary: taxed at around 30%+ marginal rate (including Medicare) for incomes above $45,000, so approximately $3,000 tax.
• As salary sacrifice: taxed at 15% inside super = $1,500 tax.
• Annual tax saving ≈ $1,500, plus $10,000 grows in super rather than after‑tax cash.

Example — worker on $120,000 (using 2025–26 marginal rates as a close proxy):

• A worked example shows that sacrificing $15,600 (maximum available after $14,400 SG) saves approximately $3,744 in income tax in a single year.
• This implies a tax saving of about $240 per $1,000 sacrificed, or $2,400 per $10,000, compared with taking it as salary.

Old vs better comparison

• “Old” (no salary sacrifice):
• On $80,000, extra $10,000 taken as salary is taxed at ~30%+ → net ≈$7,000 in hand, $3,000 lost to tax.
• “Better” (salary sacrifice):
• Same $10,000 taxed at 15% → $8,500 remains in super, only $1,500 lost to tax.

Despite the 2026 tax cut at the bottom bracket, middle‑income and higher‑income workers still save roughly 15–20 cents per dollar sacrificed, because their marginal rates remain much higher than the flat 15% contributions tax.

The second, compounding trap

Mechanism: caps, high‑income extra tax and “doing nothing” with unused cap space

• The before‑tax (concessional) contributions cap is $32,500 in 2026–27, covering employer SG, salary sacrifice, and any personal deductible contributions.
• If your income plus before‑tax contributions exceeds $250,000, an additional 15% tax (Division 293) can apply to some or all of your concessional contributions, lifting the effective tax on those contributions to 30%.
• If you do not use your concessional cap (either via salary sacrifice or deductible contributions), extra savings stay in ordinary investments or bank accounts where returns and interest are taxed at your marginal rate, often 30–45% rather than 15% in super.

Quantified long‑run cost of inaction

Take a mid‑career earner who never salary sacrifices:

• On $80,000, employer SG of $9,600 uses only 29.5% of the $32,500 concessional cap, leaving $22,900 per year unused.
• If they do not fill that cap with salary sacrifice, they miss:
• Immediate tax savings of ~$1,500 per $10,000 sacrificed (as above).
• Lower ongoing tax on investment earnings (15% in super vs 30%+ outside) for decades.

Over 20 years:

• If they could have sacrificed an extra $10,000 per year:
• Foregone annual tax saving: $1,500 × 20 = $30,000 in tax they didn’t need to pay.
• If that $8,500 after‑tax inside super earned, say, 5–6% p.a., the missed investment growth compounds significantly; even simple arithmetic shows:
• $8,500 × 20 = $170,000 of contributions not made, plus investment returns taxed at 15% instead of 30%+.

High‑income extra tax:

• For those above $250,000, concessional contributions can be effectively taxed at 30% (15% + 15% Division 293), which removes much of the advantage of salary sacrificing vs a ~30% marginal rate, but may still beat very high marginal rates closer to 45%.

In practice, failing to use concessional cap space on middle incomes can easily cost tens of thousands of dollars in avoidable tax and missed compounding over a working life.

What this looks like in practice

Persona

• Name: Sarah
• Age: 42
• Job: Marketing manager
• Income: $90,000 per year
• Super fund: large industry fund
• Current super balance: $180,000 (mid‑career estimate; not from a specific source)
• Employer SG: 12% × $90,000 = $10,800 per year.
• Years to retirement: 23 (planning to retire at 65)
• Financial year: 2026–27 concessional cap $32,500.

Discovery 1 — unused concessional cap and annual tax saving

• Sarah learns from her fund/ATO guidance that her concessional cap is $32,500, and with $10,800 SG she has $21,700 available for salary sacrifice.
• She decides to sacrifice $12,000:
• As salary, at a marginal rate around 30%+, that $12,000 would incur about $3,600+ in tax.
• As salary sacrifice, it is taxed at 15% = $1,800.
• Tax saved ≈ $1,800 per year, and $12,000 goes into super instead of after‑tax cash.
• Compared with doing nothing, she keeps an extra $1,800 per year in her own retirement pot rather than the ATO’s.

Discovery 2 — Division 293 threshold and why it doesn’t hit her

• Sarah checks the rule that if total income + before‑tax contributions exceeds $250,000, contributions can be hit with an extra 15% tax.
• Her situation:
• Income: $90,000
• Employer SG: $10,800
• Salary sacrifice: $12,000
• Total = $112,800, well below $250,000, so her concessional contributions stay taxed at 15%.
• She confirms that for her income band, salary sacrifice still enjoys the full tax discount vs 30%+ marginal rates.

Discovery 3 — long‑run effect to retirement

Assuming she keeps sacrificing $12,000 per year for 23 years:

• Annual tax saving: ≈$1,800, per Discovery 1.
• Over 23 years, simple total tax saved: $1,800 × 23 = $41,400.
• She also adds $12,000 × 23 = $276,000 in extra before‑tax contributions to super.
• Compared with “doing nothing” (no salary sacrifice), Sarah retires with roughly:
• $41,400 less tax paid overall, plus hundreds of thousands more inside a low‑tax super environment where earnings are taxed at 15% instead of her 30%+ marginal rate outside super.

These are based on straight‑line calculations using current contribution and tax rules; actual investment returns would further increase the gap.

The full cost of doing nothing

For Sarah, combining Problem 1 (not salary sacrificing) and Problem 2 (leaving concessional cap unused) over a 23‑year period:

• Extra tax she pays if she does nothing:
• Roughly $1,800 per year she could have saved via salary sacrifice on $12,000.
• $1,800 × 23 = $41,400 in avoidable tax over her working life.
• Extra money not compounding in super:
• $12,000 × 23 = $276,000 of contributions forgone.
• Headline combined impact: over $317,000 worse off on simple sums (extra tax plus missed contributions), before even counting the benefit of lower ongoing tax on super earnings.

Modelling basis:

• Income held at $90,000 for simplicity.
• SG 12% of salary; concessional cap $32,500 for 2026–27 as per current guidance.
• Salary sacrifice fixed at $12,000 p.a.; tax saving approximated using 15% contributions tax vs ~30%+ marginal rate.
• No investment return assumptions; figures show tax and contribution differences only.

What to do about it

Move 1 — Check and fill your concessional cap

1. Action: Calculate how much salary you can safely sacrifice this year.
2. Tool/portal: Use the ATO’s online services via myGov and your super fund’s online account to find:

• Your year‑to‑date employer SG contributions.
• Any personal deductible contributions already made.

3. Steps:

• Log in to myGov, go to ATO services, then to your super accounts to confirm your fund and contributions history.
• Log in to your super fund’s portal and note total employer contributions for the financial year to date.
• Subtract that figure from the $32,500 concessional cap for 2026–27 to find your remaining space, then email payroll to set a fixed salary sacrifice amount per pay that stays within this cap.

4. What “good” looks like:

• Your total before‑tax contributions (SG + salary sacrifice + deductions) are close to but under $32,500 for 2026–27, with no cap breaches.

Move 2 — Confirm your tax rate advantage

1. Action: Compare your marginal tax rate to the 15% contributions tax.
2. Tool/portal: ATO tax tables and the ATO’s salary sacrificing guidance.
3. Steps:

• Use recent ATO income tax tables to identify your marginal tax rate (including Medicare) for your income band.
• Read the ATO’s “Salary sacrificing super” page to confirm concessional contributions are taxed at 15% inside super (or 30% if you are subject to Division 293 over $250,000).
• Calculate the difference between your marginal rate and 15%; multiply that gap by the amount you plan to sacrifice to estimate your annual tax saving.

4. What “good” looks like:

• If your marginal rate is 30% or higher and you are below the $250,000 Division 293 threshold, salary sacrifice delivers a tax saving of at least 15 cents per dollar contributed.

Move 3 — Set up and monitor a written salary sacrifice agreement

1. Action: Formalise your salary sacrifice and track it over the year.
2. Tool/portal: Your employer’s payroll system, HR forms, and your super fund’s online app/portal.
3. Steps:

• Request your employer’s salary sacrifice/salary packaging form, and specify a fixed dollar amount per pay or percentage of salary, making sure the agreement is in writing before the relevant salary is earned.
• Check your first few payslips to confirm the salary sacrifice amounts are being sent to your super fund, and that reportable super contributions show correctly for tax purposes.
• Log in monthly to your super fund to ensure your total concessional contributions are tracking towards, but not beyond, the $32,500 cap.

4. What “good” looks like:

• A documented salary sacrifice arrangement, consistent contributions every pay cycle, and total concessional contributions comfortably under the cap with 15% tax applied rather than your higher marginal rate.

A myth worth clearing up

Myth: “After the 2026 tax cuts, salary sacrifice into super isn’t worth it anymore.”

Fact: Even with the 2026 cut reducing the lowest rate from 16% to 15% for incomes between $18,201 and $45,000, workers earning above $45,000 still face marginal tax rates of around 30% or more, while concessional super contributions are taxed at 15% (or 30% only for very high incomes over $250,000). For most full‑time workers, salary sacrifice still saves roughly 15–20 cents of tax per dollar contributed.
