The rent-versus-buy debate in Australia often focuses on lifestyle and property prices, but tax treatment is one of the biggest variables that people overlook. Buying an investment property unlocks deductions and CGT concessions, but it also brings stamp duty and holding costs. Renting frees up capital that could be invested in assets with their own tax advantages. Here is how the numbers actually compare in 2025-26.
Tax advantages of buying
Owner-occupied property
If you buy a home to live in, the direct tax advantages are limited:
- No capital gains tax — your principal place of residence (PPOR) is fully CGT-exempt when you sell
- No deductions — mortgage interest, council rates, and maintenance on your own home are not tax deductible
- First Home Buyer concessions — stamp duty discounts or exemptions in most states for eligible buyers
The CGT exemption is powerful if property values rise significantly, but you cannot deduct any holding costs along the way.
Investment property
Buying an investment property opens up a wider range of tax concessions:
- Negative gearing — if your rental income is less than your deductible expenses (interest, rates, insurance, repairs, depreciation), the loss reduces your taxable income from other sources like salary
- Depreciation deductions — capital works (Division 43) at 2.5% per year and plant and equipment (Division 40) items can generate significant non-cash deductions
- 50% CGT discount — if you hold for at least 12 months, only half the capital gain is taxable when you sell
- Interest deductions — the full mortgage interest on an investment loan is deductible against rental income
Tax advantages of renting (and investing the difference)
Renters do not receive any direct tax deductions on rent payments. However, the capital that would have gone into a deposit, stamp duty, and higher mortgage repayments can be deployed into other investments:
- Superannuation — concessional contributions are taxed at just 15% (or 30% for income above $250,000), far below most marginal tax rates
- Shares and ETFs — franking credits on Australian dividends reduce or eliminate double taxation; the 50% CGT discount applies after 12 months
- Salary sacrifice — additional super contributions via salary sacrifice reduce taxable income
The key question is whether the tax-advantaged returns from these alternatives outperform the tax-advantaged returns from property ownership, after all costs.
Stamp duty: the hidden tax cost of buying
Stamp duty (transfer duty) is a significant upfront tax cost that buyers face. It varies widely by state and is not deductible for owner-occupiers. Here is what you would pay on a $700,000 property in each state and territory in 2025-26:
| State/Territory | Stamp Duty on $700,000 | First Home Buyer Concession |
|---|---|---|
| NSW | $26,390 | Nil for properties under $800,000 (first home) |
| VIC | $37,070 | Nil for properties under $600,000; sliding scale to $750,000 |
| QLD | $18,025 | Concession for homes under $700,000 (first home) |
| WA | $26,015 | Nil for homes under $430,000 |
| SA | $27,830 | Nil for new homes under $650,000 (first home) |
| TAS | $24,085 | 50% discount for first home buyers |
| ACT | $23,600 | Nil for income-eligible first home buyers |
| NT | $25,317 | Stamp duty abolished for established homes (various concessions) |
For an investor who cannot access first home buyer concessions, stamp duty on a $700,000 property ranges from roughly $18,000 to $37,000 depending on the state. This is money that a renter could invest on day one.
Worked example: $700,000 property over 10 years
Let’s compare two people, both earning $120,000, both with $140,000 in savings.
Assumptions
| Item | Value |
|---|---|
| Property value | $700,000 |
| Deposit (20%) | $140,000 |
| Loan amount | $560,000 |
| Mortgage rate | 6.25% |
| Annual property growth | 4% p.a. |
| Annual rent (comparable property) | $32,000 ($615/week) |
| Annual rent growth | 3.5% p.a. |
| Share market return (after fees) | 8% p.a. |
| Marginal tax rate | 32.5% + 2% Medicare |
| Stamp duty (NSW, non-first-home-buyer) | $26,390 |
Buyer: owner-occupied
| Item | Year 1 | Over 10 Years |
|---|---|---|
| Mortgage repayments (P&I) | $41,340 | $413,400 |
| Stamp duty + legal costs | $28,390 | $28,390 (upfront) |
| Council rates, insurance, maintenance | $6,500 | $72,000 |
| Total cost of ownership | $76,230 | $513,790 |
| Property value at year 10 (4% growth) | — | $1,036,000 |
| Remaining loan balance at year 10 | — | $448,000 |
| Net equity | — | $588,000 |
Tax position: No deductions claimed (owner-occupied). No CGT on sale (PPOR exemption). The buyer’s net wealth from the property is $588,000.
Renter: investing the difference
The renter starts by investing the full $140,000 deposit plus the $28,390 they did not spend on stamp duty and legal costs — a total of $168,390 on day one. Each year they invest the difference between what the buyer pays in ownership costs and what they pay in rent.
| Item | Year 1 | Over 10 Years |
|---|---|---|
| Rent paid | $32,000 | $377,000 |
| Ownership cost the buyer paid | $76,230 | $513,790 |
| Annual saving invested (year 1) | $44,230 | varies |
| Starting investment | $168,390 | — |
| Portfolio value at year 10 (8% gross) | — | $730,000 |
| Less: Estimated CGT on unrealised gains (32.5% x 50% discount) | — | -$52,000 |
| Net portfolio after CGT | — | $678,000 |
Tax position: Dividends taxed each year at the marginal rate (partially offset by franking credits). CGT discount of 50% applies on sale. The renter’s estimated net wealth from investments is $678,000.
Summary comparison
| Metric | Buyer | Renter + Investor |
|---|---|---|
| Gross asset value at year 10 | $1,036,000 | $730,000 |
| Less: Debt / CGT liability | -$448,000 | -$52,000 |
| Net wealth from strategy | $588,000 | $678,000 |
In this scenario, the renter who invests the difference comes out ahead by roughly $90,000 over 10 years, primarily because of the large upfront stamp duty cost and high mortgage interest in the early years. However, the buyer has no CGT to pay on their PPOR and benefits more from leverage if property growth exceeds 4%.
When buying wins
- Property growth exceeds 5-6% per year (leverage amplifies gains)
- You plan to live in the home for 15+ years (stamp duty cost is amortised, full CGT exemption)
- You are buying an investment property and can claim negative gearing, depreciation, and interest deductions
- Mortgage rates fall significantly during the holding period
- You lack the discipline to consistently invest the difference
When renting + investing wins
- You are in a high-stamp-duty state and plan to move within 5-7 years
- Share market returns are strong (historically 8-10% long-term in Australia)
- You maximise super contributions at 15% tax (far below most marginal rates)
- Property growth is modest (2-3% in your target area)
- You value flexibility — job changes, lifestyle changes, location changes
Key takeaways
- Owner-occupied buyers get CGT exemption but cannot deduct mortgage interest — the main tax benefit is on sale, not while holding
- Investment property buyers get negative gearing and the CGT discount, making the tax position materially different from owner-occupiers
- Stamp duty is a substantial upfront tax cost — $18,000 to $37,000 on a $700,000 property depending on the state
- Renters can redirect savings into super (15% tax) and shares (CGT discount + franking credits) for competitive after-tax returns
- The breakeven point depends heavily on property growth rate, holding period, and stamp duty costs
