Negative Gearing vs Super: Where Should Your Tax Strategy Live?
Negative gearing is the most-pitched, least-questioned tax strategy in Australia. The story is simple: borrow to buy a property, lose money on it each year, claim the loss against your salary, and ride the capital growth. But when you stack the same dollars side-by-side against extra super contributions over 25 years, the gap is much smaller than the spruikers suggest — and the risks look very different.

What Negative Gearing Actually Is
Negative gearing isn't a strategy — it's a tax outcome. If your investment property's deductible expenses (interest, council rates, repairs, depreciation, agent fees) are greater than the rent it brings in, you've made a tax loss. Australian tax law lets you offset that loss against your other income, including your salary. So a $15,000 paper loss on your property reduces your taxable income by $15,000, and at the top marginal rate that's worth around $7,000 back in your pocket each year.
The pitch usually stops there: "the tax man pays for half your investment." What it skips over is that you still have to fund the cash shortfall every month, the property has to actually grow, and at the end of the road there's a capital gains bill waiting. The whole approach only really works if the property appreciates strongly enough to swamp years of cash losses.
Worth knowing: Negative gearing has nothing to do with whether the investment is good. It just describes the tax position. A profitable investment property is positively geared. A loss-making one becomes a tax shelter only because Australia allows the offset — most countries don't.
A 25-Year Comparison
Let's run Mia, a 40-year-old IT manager in Sydney earning $130,000. She's choosing between two paths for the same pool of money over the next 25 years, until she's 65.
Path A — Negative gearing: Buy a $650,000 investment property in Brisbane. Use a $130,000 deposit and put $30,000 into stamp duty and other costs ($160,000 upfront). Take an interest-only loan of $520,000 at 6.2%. Rent comes in at around $30,000 per year, gross expenses run about $48,000, leaving an $18,000 paper loss each year (after depreciation). The tax saving at her marginal rate is roughly $7,000, so her real out-of-pocket is about $11,000 a year.
Path B — Super: Take the same dollars — $160,000 upfront and $11,000 a year — and direct them into super as concessional contributions instead. The upfront chunk is spread over the available cap (and any catch-up room), the annual top-up is a salary sacrifice or personal deductible contribution within the $30,000 cap.
| Detail | Negative gearing | Extra super |
|---|---|---|
| Upfront outlay | $160,000 | $160,000 |
| Annual cost (after tax) | ~$11,000 | ~$11,000 |
| Asset value at age 65 | ~$2.20M (5% growth) | ~$1.55M super balance |
| Less remaining loan | $520,000 | — |
| Less tax on exit | ~$300,000 CGT | $0 (pension phase, under TBC) |
| Net wealth at 65 | ~$1.38M | ~$1.55M |
The result is roughly a wash — and in this run, super edges ahead. The leverage advantage that property gets early is largely cancelled by the loan principal still owing, the CGT bill on exit, and the cash drag along the way. Super doesn't borrow, but it pays only 15% tax on contributions and 15% on earnings (often less after franking credits), and zero in pension phase up to the Transfer Balance Cap.
Example: Year-by-year cash flow
Year 1: Mia pays $11,000 out of pocket on the property. The same $11,000 in super becomes about $9,350 inside the fund (after 15% contributions tax). Property is "free leverage" on $650K; super is steady compounding on a smaller base.
Year 10: Property has grown to ~$1.06M. Super contributions have built up to roughly $250K. Property looks ahead — but Mia has paid $110,000 of after-tax cash to keep the lights on.
Year 25 (age 65): Property worth $2.2M, less $520K loan, less ~$300K CGT = $1.38M net. Super has compounded to ~$1.55M, fully tax-free if drawn as a pension under the cap.
Why the Property Pitch Tells Half the Story
Three things the typical negative gearing sales deck quietly skips over:
- The capital gains tax bill at the end. The 50% CGT discount helps, but on a sale where the gain is $1M+, the remaining tax bite at top marginal rates is enormous. Many investors are shocked when they finally sell.
- You still owe the loan. Interest-only loans don't pay themselves off. P&I loans cost more each month and reduce the negative-gearing benefit. Either way, the loan balance comes off your equity at sale.
- Single-asset concentration risk. One property in one suburb is one bet. If the local market stalls (Perth in the 2010s, parts of regional Australia, or any postcode with a planning shock), the leverage works against you.
Negative gearing also assumes you stay employed at a high marginal tax rate. Drop down a bracket — career change, parental leave, business downturn — and the tax shield shrinks. Super's tax benefits don't depend on your income holding up.
Where Property Genuinely Wins
This isn't a one-sided story. Property has real advantages super can't match:
- Leverage. A $130K deposit controls a $650K asset. No super contribution gives you that.
- Access before 60. You can sell or borrow against a property at any age. Super is locked away until preservation age.
- Forced saving. The mortgage payment turns up every month whether you feel like it or not. Many investors find this discipline easier than voluntary super contributions.
- Diversification. If your super is already huge, an investment property genuinely diversifies your wealth into another asset class.
The honest version: Property and super aren't either/or. Plenty of well-off Australians retire with both. The question isn't which is "better" — it's which suits your stage, cash flow, risk tolerance, and how locked-in you can afford your money to be.
What Often Gets Missed in the Numbers
Vacancy, repairs, and rent stagnation
The model above assumes 100% occupancy and steady rent. In reality, vacancy averages around 2–3% per year nationally and can spike higher. Repairs eat into the cash flow at unpredictable times. A new hot water system, roof repair, or special body corporate levy can wipe out a year of "savings."
Interest rate movements
The whole negative-gearing maths is sensitive to interest rates. The same property can be lightly negatively geared at 4% interest and brutally cash-negative at 7%. Many investors who bought in the low-rate era of 2019–2021 were caught flat-footed when the cash rate climbed.
Depreciation drying up
Depreciation deductions are biggest in the first few years and taper down. By year 10, the paper loss may be much smaller than year 1, even if cash flow hasn't improved. The tax shield isn't constant.
What Talk Through Wealth Shows You
Pitches and spreadsheets show you one path. Talk Through Wealth lets you compare them side-by-side over your actual lifetime:
- Model a negatively geared property with realistic vacancy, interest rate scenarios, and exit CGT
- Compare the same dollars going into super under your concessional cap and bring-forward room
- See how preservation age affects your access — what's available at 60, what's stuck
- Layer in Age Pension means testing, since both paths affect it differently
- Stress-test against rate hikes, vacancy spikes, and slower property growth
Have a play with the property growth assumption. Drop it from 5% to 3.5% and see how quickly the gearing case unravels. That's the conversation the brochures don't have.
