Two stories, one principle: structure determines how much wealth you keep over a lifetime.
Why Stories Work
Tax concepts are abstract until you see them play out in real dollars over real time. We follow Sarah and Michael (two investors) and Dave (a business owner) to show how the same money, handled differently, produces dramatically different outcomes.
Two investors. One business owner. Same money. Very different outcomes.
Stuck on a term? CGT discount, SMSF pension phase, discretionary trust β find plain-English definitions in our Tax & Investing Glossary.
See the glossary βSame Money, Different Outcomes
Two investors. Same $100,000 starting capital. Same 8% annual returns. Different structures. Dramatically different outcomes.
Sarah, 35
Personal Post-Tax Investing
β’ Invests $100,000 of after-tax money in her own name
β’ Pays 40% tax on investment income each year
β’ Pays 20% CGT when rebalancing (50% discount applied)
β’ Simple setup β but high ongoing tax drag
Michael, 35
SMSF Structure
β’ Invests $100,000 via a Self-Managed Super Fund
β’ Pays only 15% tax on investment income
β’ Pays only 10% CGT when rebalancing
β’ More setup β but dramatically lower tax drag
Let's follow their 25-year journey...
The 25-Year Journey
Years 1β5: The Tax Bite Begins
Sarah's Experience
Michael's Experience
Just a $13,000 gap after 5 years. This is about to compound dramatically.
Year 10: The Crossover Point
Sarah's Portfolio
$216,000
Michael's Portfolio
$293,000
Wealth Gap at Year 10
$77,000
Michael has 35% more wealth from structure alone
The Rebalancing Test
Both decide to rebalance β selling some shares to buy bonds. This triggers a CGT event.
Sarah's CGT Bill
Michael's CGT Bill
$9,000 Saved Every Time They Rebalance
Year 25: The Final Tally
Same starting capital. Same returns. Different structures.
Sarah (Personal)
$265,000
Michael (SMSF)
$480,000
Michael's Advantage
$215,000 more
That's 81% more wealth from structure choice alone.
Where Did Sarah's Money Go?
Michael's Advantage
But Wait... The Pension Phase Game Changer
At Age 60, Michael Switches to Pension Phase
This is a legal structure change inside his SMSF that completely transforms his tax situation:
0%
Tax on income
0%
Tax on capital gains
0%
Tax on withdrawals (60+)
His $480,000 at age 60 now grows completely tax-free. He can still trade, rebalance, and adjust his portfolio as much as he likes β every dollar of income and every capital gain compounds without any tax drag at all.
Sarah at 80 (Personal)
$580k
Michael at 80 (SMSF Pension)
$2.2M
Lifetime Structure Difference
$1.6 MILLION
Same starting capital. Same returns. Same risk. Just different structure decisions.

Key Insights From Both Stories

One Size Never Fits All
Your Options: All 7 Structures Compared
Now you understand why Michael chose an SMSF. Here are all seven Australian investment structures compared side-by-side.
| Structure | Control | Tax on Contributions | Tax on Income | Effective CGT | Liability Protection | After-Tax Return |
|---|---|---|---|---|---|---|
| Personal (Post-Tax) | High | 35β40% (already paid) | 35β40% | 17.5β20% | Low | ~4.8% |
| Industry / Retail Super | Medium | 15% | 15% | 10% | High | ~6.8% |
| SMSF (Accumulation) | Very High | 15% | 15% | 10% | Very High | ~6.8% |
SMSF (Pension Phase) | Very High | N/A | 0% | 0% | Very High | ~8.0% |
| Family / Discretionary Trust | High | Post-tax | Distributed to beneficiaries | 17.5β20% | Moderate | ~5.5β6.5% |
| Company (Pty Ltd) | Very High | Post-tax | 25β30% flat | No discount | Very High | ~5.6β6.0% |
| Unit Trust | Medium | Post-tax | Distributed to unit holders | 17.5β20% | Moderate | ~5.5β6.5% |

SMSF Pension Phase offers the highest after-tax returns (available from age 60).
- Sarah ends up with $265k. Michael ends up with $480k at year 25 β and $2.2M at 80. Same money, different structures.
- SMSF pension phase is 0% tax on income, gains, and withdrawals. It's the most tax-efficient structure in Australia.
- The gap between structures accelerates: $13k at year 5, $77k at year 10, $215k at year 25, then $1.6M over a lifetime.
Homework
Which investor's situation most resembles yours: Sarah (personal), Michael (SMSF), or Dave (business owner)? What structure change could benefit you most?
Identify your current investment structure. For each investment you own, write down: what structure is it held in, what tax rate applies, and what would change if you moved to an SMSF or trust.
